AH1 MOD 6 CARDIO Shock Iggy NCLEX, Iggy Chp 35 - Care of Patients with Cardiac Problems, CH 33, 35 Cardiac, Nursing Management: Coronary Artery Disease and Acute Coronary Syndrome, Nursing Assessment: Cardiovascular System

The client in shock has the following vital signs: T 99.8° F, P 132 beats/min, R 32 breaths/min, and BP 80/58 mm Hg. Calculate the pulse pressure.

22 mm Hg Pulse pressure is the difference between the systolic and diastolic pressures: 80 (systolic) - 58 (diastolic) = 22 (pulse pressure)

Physiological Integrity 29. When caring for a patient who has just arrived on the medical-surgical unit after having cardiac catheterization, which nursing intervention should the nurse delegate to a licensed practical/vocational nurse (LPN/LVN)? a. Give the scheduled aspirin and lipid-lowering medication. b. Perform the initial assessment of the catheter insertion site. c. Teach the patient about the usual postprocedure plan of care. d. Titrate the heparin infusion according to the agency protocol.

A Administration of oral medications is within the scope of practice for LPNs/LVNs. The initial assessment of the patient, patient teaching, and titration of IV anticoagulant medications should be done by the registered nurse (RN).

Physiological Integrity 34. Which information about a patient who has been receiving thrombolytic therapy for an acute myocardial infarction (AMI) is most important for the nurse to communicate to the health care provider? a. No change in the patient's chest pain b. An increase in troponin levels from baseline c. A large bruise at the patient's IV insertion site d. A decrease in ST-segment elevation on the electrocardiogram

A Continued chest pain suggests that the thrombolytic therapy is not effective and that other interventions such as percutaneous coronary intervention (PCI) may be needed. Bruising is a possible side effect of thrombolytic therapy, but it is not an indication that therapy should be discontinued. The decrease of the ST-segment elevation indicates that thrombolysis is occurring and perfusion is returning to the injured myocardium. An increase in troponin levels is expected with reperfusion and is related to the washout of cardiac markers into the circulation as the blocked vessel is opened.

Physiological Integrity 25. The nurse is caring for a patient who was admitted to the coronary care unit following an acute myocardial infarction (AMI) and percutaneous coronary intervention the previous day. Teaching for this patient would include a. when cardiac rehabilitation will begin. b. the typical emotional responses to AMI. c. information regarding discharge medications. d. the pathophysiology of coronary artery disease.

A Early after an AMI, the patient will want to know when resumption of usual activities can be expected. At this time, the patient's anxiety level or denial will interfere with good understanding of complex information such as the pathophysiology of coronary artery disease (CAD). Teaching about discharge medications should be done closer to discharge. The nurse should support the patient by decreasing anxiety rather than discussing the typical emotional responses to myocardial infarction (MI).

Physiological Integrity 4. To auscultate for S3 or S4 gallops in the mitral area, the nurse listens with the a. bell of the stethoscope with the patient in the left lateral position. b. diaphragm of the stethoscope with the patient in a supine position. c. bell of the stethoscope with the patient sitting and leaning forward. d. diaphragm of the stethoscope with the patient lying flat on the left side.

A Gallop rhythms generate low-pitched sounds and are most easily heard with the bell of the stethoscope. Sounds associated with the mitral valve are accentuated by turning the patient to the left side, which brings the heart closer to the chest wall. The diaphragm of the stethoscope is best to use for the higher-pitched sounds such as S1 and S2. DIF: Cognitive Level: Apply (application) REF: 697 TOP: Nursing Process: Assessment MSC:

Psychosocial Integrity 26. A patient who has recently started taking pravastatin (Pravachol) and niacin (Nicobid) reports the following symptoms to the nurse. Which is most important to communicate to the health care provider? a. Generalized muscle aches and pains b. Dizziness when changing positions quickly c. Nausea when taking the drugs before eating d. Flushing and pruritus after taking the medications

A Muscle aches and pains may indicate myopathy and rhabdomyolysis, which have caused acute kidney injury and death in some patients who have taken the statin medications. These symptoms indicate that the pravastatin may need to be discontinued. The other symptoms are common side effects when taking niacin, and although the nurse should follow-up with the health care provider, they do not indicate that a change in medication is needed.

21. A patient with ADHF who is receiving nesiritide (Natrecor) asks the nurse how the medication will work to help improve the symptoms of dyspnea and orthopnea. The nurse's reply will be based on the information that nesiritide will a. dilate arterial and venous blood vessels, decreasing ventricular preload and afterload. b. improve the ability of the ventricular myocardium to contract, strengthening contractility. c. enhance the speed of impulse conduction through the heart, increasing the heart rate. d. increase calcium sensitivity in vascular smooth muscle, boosting systemic vascular resistance.

A Rationale: Nesiritide, a recombinant form of BNP, causes both arterial and venous vasodilation, leading to reductions in preload and afterload. Inotropic medications, such as dopamine and dobutamine, may be used in ADHF to improve ventricular contractility. Nesiritide does not increase impulse conduction or calcium sensitivity in the heart.

19. An outpatient who has developed heart failure after having an acute myocardial infarction has a new prescription for carvedilol (Coreg). After 2 weeks, the patient returns to the clinic. The assessment finding that will be of most concern to the nurse is that the patient a. has BP of 88/42. b. has an apical pulse rate of 56. c. complains of feeling tired. d. has 2+ pedal edema.

A Rationale: The patient's BP indicates that the dose of carvedilol may need to be decreased because the mean arterial pressure is only 57. Bradycardia is a frequent adverse effect of -Adrenergic blockade, but the rate of 56 is not as great a concern as the hypotension. -adrenergic blockade will initially worsen symptoms of heart failure in many patients, and patients should be taught that some increase in symptoms, such as fatigue and edema, is expected during the initiation of therapy with this class of drugs.

Physiological Integrity 13. The nurse hears a murmur between the S1 and S2 heart sounds at the patient's left fifth intercostal space and midclavicular line. How will the nurse record this information? a. Systolic murmur heard at mitral area b. Systolic murmur heard at Erb's point c. Diastolic murmur heard at aortic area d. Diastolic murmur heard at the point of maximal impulse

A The S1 signifies the onset of ventricular systole. S2 signifies the onset of diastole. A murmur occurring between these two sounds is a systolic murmur. The mitral area is the intersection of the left fifth intercostal space and the midclavicular line. The other responses describe murmurs heard at different landmarks on the chest and/or during the diastolic phase of the cardiac cycle.

Physiological Integrity 18. The standard policy on the cardiac unit states, "Notify the health care provider for mean arterial pressure (MAP) less than 70 mm Hg." The nurse will need to call the health care provider about the a. postoperative patient with a BP of 116/42. b. newly admitted patient with a BP of 150/87. c. patient with left ventricular failure who has a BP of 110/70. d. patient with a myocardial infarction who has a BP of 140/86.

A The mean arterial pressure (MAP) is calculated using the formula MAP = (systolic BP + 2 diastolic BP)/3. The MAP for the postoperative patient in answer 3 is 67. The MAP in the other three patients is higher than 70 mm Hg. DIF: Cognitive Level: Apply (application) REF: 690-691 TOP: Nursing Process: Assessment MSC:

Physiological Integrity 27. A patient who is being admitted to the emergency department with intermittent chest pain gives the following list of medications to the nurse. Which medication has the most immediate implications for the patient's care? a. Sildenafil (Viagra) b. Furosemide (Lasix) c. Captopril (Capoten) d. Warfarin (Coumadin)

A The nurse will need to avoid giving nitrates to the patient because nitrate administration is contraindicated in patients who are using sildenafil because of the risk of severe hypotension caused by vasodilation. The other home medications also should be documented and reported to the health care provider but do not have as immediate an impact on decisions about the patient's treatment.

Physiological Integrity 19. Three days after experiencing a myocardial infarction (MI), a patient who is scheduled for discharge asks for assistance with hygiene activities, saying, "I am too nervous to take care of myself." Based on this information, which nursing diagnosis is appropriate? a. Ineffective coping related to anxiety b. Activity intolerance related to weakness c. Denial related to lack of acceptance of the MI d. Disturbed personal identity related to understanding of illness

A The patient data indicate that ineffective coping after the MI caused by anxiety about the impact of the MI is a concern. The other nursing diagnoses may be appropriate for some patients after an MI, but the data for this patient do not support denial, activity intolerance, or disturbed personal identity. DIF: Cognitive Level: Apply (application) REF: 757 TOP: Nursing Process: Diagnosis MSC:

Physiological Integrity 21. A few days after experiencing a myocardial infarction (MI) and successful percutaneous coronary intervention, the patient states, "I just had a little chest pain. As soon as I get out of here, I'm going for my vacation as planned." Which reply would be most appropriate for the nurse to make? a. "What do you think caused your chest pain?" b. "Where are you planning to go for your vacation?" c. "Sometimes plans need to change after a heart attack." d. "Recovery from a heart attack takes at least a few weeks."

A When the patient is experiencing denial, the nurse should assist the patient in testing reality until the patient has progressed beyond this step of the emotional adjustment to MI. Asking the patient about vacation plans reinforces the patient's plan, which is not appropriate in the immediate post-MI period. Reminding the patient in denial about the MI is likely to make the patient angry and lead to distrust of the nursing staff.

The nurse discusses the importance of restricting sodium in the diet for a client with heart failure. Which statement made by the client indicates that the client needs further teaching? A) "I should avoid eating hamburgers." B) "I must cut out bacon and canned foods." C) "I shouldn't put the salt shaker on the table anymore." D) "I should avoid lunchmeats but may cook my own turkey." (Chp. 35; elsevier)

A) "I should avoid eating hamburgers." (Chp. 35; elsevier)

Physiological Integrity 10. When auscultating over the patient's abdominal aorta, the nurse hears a humming sound. The nurse documents this finding as a a. thrill. b. bruit. c. murmur. d. normal finding.

B A bruit is the sound created by turbulent blood flow in an artery. Thrills are palpable vibrations felt when there is turbulent blood flow through the heart or in a blood vessel. A murmur is the sound caused by turbulent blood flow through the heart. Auscultating a bruit in an artery is not normal and indicates pathology.

Physiological Integrity 7. A patient is scheduled for a cardiac catheterization with coronary angiography. Before the test, the nurse informs the patient that a. it will be important to lie completely still during the procedure. b. a flushed feeling may be noted when the contrast dye is injected. c. monitored anesthesia care will be provided during the procedure. d. arterial pressure monitoring will be required for 24 hours after the test.

B A sensation of warmth or flushing is common when the contrast material is injected, which can be anxiety-producing unless it has been discussed with the patient. The patient may receive a sedative drug before the procedure, but monitored anesthesia care is not used. Arterial pressure monitoring is not routinely used after the procedure to monitor blood pressure. The patient is not immobile during cardiac catheterization and may be asked to cough or take deep breaths.

Physiological Integrity 33. When admitting a patient with a non-ST-segment-elevation myocardial infarction (NSTEMI) to the intensive care unit, which action should the nurse perform first? a. Obtain the blood pressure. b. Attach the cardiac monitor. c. Assess the peripheral pulses. d. Auscultate the breath sounds.

B Because dysrhythmias are the most common complication of myocardial infarction (MI), the first action should be to place the patient on a cardiac monitor. The other actions also are important and should be accomplished as quickly as possible.

Physiological Integrity 39. To improve the physical activity level for a mildly obese 71-year-old patient, which action should the nurse plan to take? a. Stress that weight loss is a major benefit of increased exercise. b. Determine what kind of physical activities the patient usually enjoys. c. Tell the patient that older adults should exercise for no more than 20 minutes at a time. d. Teach the patient to include a short warm-up period at the beginning of physical activity.

B Because patients are more likely to continue physical activities that they already enjoy, the nurse will plan to ask the patient about preferred activities. The goal for older adults is 30 minutes of moderate activity on most days. Older adults should plan for a longer warm-up period. Benefits of exercises, such as improved activity tolerance, should be emphasized rather than aiming for significant weight loss in older mildly obese adults.

Physiological Integrity 3. Which assessment data collected by the nurse who is admitting a patient with chest pain suggest that the pain is caused by an acute myocardial infarction (AMI)? a. The pain increases with deep breathing. b. The pain has lasted longer than 30 minutes. c. The pain is relieved after the patient takes nitroglycerin. d. The pain is reproducible when the patient raises the arms.

B Chest pain that lasts for 20 minutes or more is characteristic of AMI. Changes in pain that occur with raising the arms or with deep breathing are more typical of musculoskeletal pain or pericarditis. Stable angina is usually relieved when the patient takes nitroglycerin. DIF: Cognitive Level: Apply (application) REF: 748 TOP: Nursing Process: Assessment MSC:

Psychosocial Integrity 20. When caring for a patient who is recovering from a sudden cardiac death (SCD) event and has no evidence of an acute myocardial infarction (AMI), the nurse will anticipate teaching the patient that a. sudden cardiac death events rarely reoccur. b. additional diagnostic testing will be required. c. long-term anticoagulation therapy will be needed. d. limited physical activity after discharge will be needed to prevent future events.

B Diagnostic testing (e.g., stress test, Holter monitor, electrophysiologic studies, cardiac catheterization) is used to determine the possible cause of the SCD and treatment options. SCD is likely to recur. Anticoagulation therapy will not have any effect on the incidence of SCD, and SCD can occur even when the patient is resting.

Physiological Integrity 12. When assessing a newly admitted patient, the nurse notes a murmur along the left sternal border. To document more information about the murmur, which action will the nurse take next? a. Find the point of maximal impulse. b. Determine the timing of the murmur. c. Compare the apical and radial pulse rates. d. Palpate the quality of the peripheral pulses.

B Murmurs are caused by turbulent blood flow, such as occurs when blood flows through a damaged valve. Relevant information includes the position in which the murmur is heard best (e.g., sitting and leaning forward), the timing of the murmur in relation to the cardiac cycle (e.g., systole, diastole), and where on the thorax the murmur is heard best. The other information is also important in the cardiac assessment but will not provide information that is relevant to the murmur.

Physiological Integrity 10. The nurse will suspect that the patient with stable angina is experiencing a side effect of the prescribed metoprolol (Lopressor) if the a. patient is restless and agitated. b. blood pressure is 90/54 mm Hg. c. patient complains about feeling anxious. d. cardiac monitor shows a heart rate of 61 beats/minute.

B Patients taking -adrenergic blockers should be monitored for hypotension and bradycardia. Because this class of medication inhibits the sympathetic nervous system, restlessness, agitation, hypertension, and anxiety will not be side effects.

Physiological Integrity 7. After the nurse teaches the patient about the use of carvedilol (Coreg) in preventing anginal episodes, which statement by a patient indicates that the teaching has been effective? a. "Carvedilol will help my heart muscle work harder." b. "It is important not to suddenly stop taking the carvedilol." c. "I can expect to feel short of breath when taking carvedilol." d. "Carvedilol will increase the blood flow to my heart muscle."

B Patients who have been taking -adrenergic blockers can develop intense and frequent angina if the medication is suddenly discontinued. Carvedilol (Coreg) decreases myocardial contractility. Shortness of breath that occurs when taking -adrenergic blockers for angina may be due to bronchospasm and should be reported to the health care provider. Carvedilol works by decreasing myocardial oxygen demand, not by increasing blood flow to the coronary arteries.

Physiological Integrity 9. Diltiazem (Cardizem) is ordered for a patient with newly diagnosed Prinzmetal's (variant) angina. When teaching the patient, the nurse will include the information that diltiazem will a. reduce heart palpitations. b. decrease spasm of the coronary arteries. c. increase the force of the heart contractions. d. help prevent plaque from forming in the coronary arteries.

B Prinzmetal's angina is caused by coronary artery spasm. Calcium channel blockers (e.g., diltiazem, amlodipine [Norvasc]) are a first-line therapy for this type of angina. Lipid-lowering drugs help reduce atherosclerosis (i.e., plaque formation), and -adrenergic blockers decrease sympathetic stimulation of the heart (i.e., palpitations). Medications or activities that increase myocardial contractility will increase the incidence of angina by increasing oxygen demand.

22. A patient who is receiving dobutamine (Dobutrex) for the treatment of ADHF has all of the following nursing actions included in the plan of care. Which action will be best for the RN to delegate to an experienced LPN/LVN? a. Teach the patient the reasons for remaining on bed rest. b. Monitor the patient's BP every hour. c. Adjust the drip rate to keep the systolic BP >90 mm Hg. d. Call the health care provider about a decrease in urine output.

B Rationale: An experienced LPN/LVN would be able to monitor BP and would know to report significant changes to the RN. Teaching patients and making adjustments to the drip rate for vasoactive medications are RN-level skills. Because the health care provider may order changes in therapy based on the decrease in urine output, the RN should call the health care provider about the decreased urine output.

The RN will need to intervene immediately if the student nurse a. presses on the skin over the tibia for 10 seconds to check for edema. b. palpates both carotid arteries simultaneously to compare pulse quality. c. documents a murmur heard along the right sternal border as a pulmonic murmur. d. places the patient in the left lateral position to check for the point of maximal impulse.

B The carotid pulses should never be palpated at the same time to avoid vagal stimulation, dysrhythmias, and decreased cerebral blood flow. The other assessment techniques also need to be corrected. However, they are not dangerous to the patient. DIF: Cognitive Level: Apply (application) REF: 694-695 TOP: Nursing Process: Assessment MSC:

Physiological Integrity 28. Which assessment finding by the nurse caring for a patient who has had coronary artery bypass grafting using a right radial artery graft is most important to communicate to the health care provider? a. Complaints of incisional chest pain b. Pallor and weakness of the right hand c. Fine crackles heard at both lung bases d. Redness on both sides of the sternal incision

B The changes in the right hand indicate compromised blood flow, which requires immediate evaluation and actions such as prescribed calcium channel blockers or surgery.

The patient's pedal pulses are +1. b. The patient is allergic to shellfish. c. The patient had a heart attack a year ago. d. The patient has not eaten anything today.

B The contrast dye used for the procedure is iodine based, so patients who have shellfish allergies will require treatment with medications such as corticosteroids and antihistamines before the angiogram. The other information is also communicated to the health care provider but will not require a change in the usual precardiac catheterization orders or medications.

When titrating IV nitroglycerin (Tridil) for a patient with a myocardial infarction (MI), which action will the nurse take to evaluate the effectiveness of the medication? a. Monitor heart rate. b. Ask about chest pain. c. Check blood pressure. d. Observe for dysrhythmias.

B The goal of IV nitroglycerin administration in MI is relief of chest pain by improving the balance between myocardial oxygen supply and demand. The nurse also will monitor heart rate and blood pressure (BP) and observe for dysrhythmias, but these parameters will not indicate whether the medication is effective.

Which signs and symptoms are seen with suspected pericarditis? (Select all that apply.) Squeezing, vise-like chest pain Chest pain relieved by sitting upright Chest and abdominal pain relieved by antacids Sudden-onset chest pain relieved by anti-inflammatory agents Pain in the chest described as sharp or stabbing

B.D.E. The pain of pericarditis is relieved when sitting upright or forward, may appear abruptly, and is relieved by anti-inflammatory agents. The inflammatory pain of pericarditis tends to be sharp, stabbing, and related to breathing; squeezing, vise-like chest pain is characteristic of myocardial infarction. Chest and abdominal pain relieved by antacids is characteristic of peptic ulcer.

Physiological Integrity 15. Following an acute myocardial infarction (AMI), a patient ambulates in the hospital hallway. When the nurse is evaluating the patient's response to the activity, which assessment data would indicate that the exercise level should be decreased? a. Blood pressure (BP) changes from 118/60 to 126/68 mm Hg. b. Oxygen saturation drops from 99% to 95%. c. Heart rate increases from 66 to 92 beats/minute. d. Respiratory rate goes from 14 to 20 breaths/minute.

C A change in heart rate of more than 20 beats over the resting heart rate indicates that the patient should stop and rest. The increases in BP and respiratory rate, and the slight decrease in oxygen saturation, are normal responses to exercise.

Physiological Integrity 11. The nurse has received the laboratory results for a patient who developed chest pain 4 hours ago and may be having a myocardial infarction. The most important laboratory result to review will be a. myoglobin. b. low-density lipoprotein (LDL) cholesterol. c. troponins T and I. d. creatine kinase-MB (CK-MB).

C Cardiac troponins start to elevate 4 to 6 hours after myocardial injury and are highly specific to myocardium. They are the preferred diagnostic marker for myocardial infarction. Myoglobin rises in response to myocardial injury within 30 to 60 minutes. It is rapidly cleared from the body, thus limiting its use in the diagnosis of myocardial infarction. LDL cholesterol is useful in assessing cardiovascular risk but is not helpful in determining whether a patient is having an acute myocardial infarction. Creatine kinase (CK-MB) is specific to myocardial injury and infarction and increases 4 to 6 hours after the infarction occurs. It is often trended with troponin levels.

Heparin enhances platelet aggregation. b. Heparin decreases coronary artery plaque size. c. Heparin prevents the development of new clots in the coronary arteries. d. Heparin dissolves clots that are blocking blood flow in the coronary arteries.

C Heparin helps prevent the conversion of fibrinogen to fibrin and decreases coronary artery thrombosis. It does not change coronary artery plaque, dissolve already formed clots, or enhance platelet aggregation.

Health Promotion and Maintenance 2. Which nursing intervention will be most effective when assisting the patient with coronary artery disease (CAD) to make appropriate dietary changes? a. Give the patient a list of low-sodium, low-cholesterol foods that should be included in the diet. b. Emphasize the increased risk for heart problems unless the patient makes the dietary changes. c. Help the patient modify favorite high-fat recipes by using monosaturated oils when possible. d. Inform the patient that a diet containing no saturated fat and minimal salt will be necessary.

C Lifestyle changes are more likely to be successful when consideration is given to the patient's values and preferences. The highest percentage of calories from fat should come from monosaturated fats. Although low-sodium and low-cholesterol foods are appropriate, providing the patient with a list alone is not likely to be successful in making dietary changes. Completely removing saturated fat from the diet is not a realistic expectation. Up to 7% of calories in the therapeutic lifestyle changes (TLC) diet can come from saturated fat. Telling the patient about the increased risk without assisting further with strategies for dietary change is unlikely to be successful.

20. An elderly patient with a 40-pack-year history of smoking and a recent myocardial infarction is admitted to the medical unit with acute shortness of breath; the nurse need to rule out pneumonia versus heart failure. The diagnostic test that the nurse will monitor to help in determining whether the patient has heart failure is a. 12-lead electrocardiogram (ECG). b. arterial blood gases (ABGs). c. B-type natriuretic peptide (BNP). d. serum creatine kinase (CK).

C Rationale: BNP is secreted when ventricular pressures increase, as with heart failure, and elevated BNP indicates a probable or very probable diagnosis of heart failure. 12-lead ECGs, ABGs, and CK may also be used in determining the causes or effects of heart failure but are not as clearly diagnostic of heart failure as BNP.

During the administration of the thrombolytic agent to a patient with an acute myocardial infarction (AMI), the nurse should stop the drug infusion if the patient experiences a. bleeding from the gums. b. increase in blood pressure. c. a decrease in level of consciousness. d. a nonsustained episode of ventricular tachycardia.

C The change in level of consciousness indicates that the patient may be experiencing intracranial bleeding, a possible complication of thrombolytic therapy. Some bleeding of the gums is an expected side effect of the therapy but not an indication to stop infusion of the thrombolytic medication. A decrease in blood pressure could indicate internal bleeding. A nonsustained episode of ventricular tachycardia is a common reperfusion dysrhythmia and may indicate that the therapy is effective.

Bilateral crackles are auscultated in the mid-lower lobes. d. The patient has occasional premature atrial contractions (PACs).

C The crackles indicate that the patient may be developing heart failure, a possible complication of myocardial infarction (MI). The health care provider may need to order medications such as diuretics or angiotensin-converting enzyme (ACE) inhibitors for the patient. Elevation in troponin level at this time is expected.

Physiological Integrity 5. After the nurse has finished teaching a patient about the use of sublingual nitroglycerin (Nitrostat), which patient statement indicates that the teaching has been effective? a.

"I will call an ambulance if I still have pain after taking 3 nitroglycerin 5 minutes apart." d. "Nitroglycerin helps prevent a clot from forming and blocking blood flow to my heart."

C The emergency medical services (EMS) system should be activated when chest pain or other symptoms are not completely relieved after 3 sublingual nitroglycerin tablets taken 5 minutes apart. Nitroglycerin can be taken to prevent chest pain or other symptoms from developing (e.g., before intercourse). Gastric upset (e.g., nausea) is not an expected side effect of nitroglycerin.

Importance of daily physical activity b. Effect of weight loss on blood pressure c. Dietary changes to improve lipid levels d. Ongoing cardiac risk associated with history of tobacco use

C The patient has an elevated low-density lipoprotein (LDL) cholesterol and low high-density lipoprotein (HDL) cholesterol, which will increase the risk of coronary artery disease. Although the blood pressure is in the prehypertensive range, the patient's waist circumference and body mass index (BMI) indicate an appropriate body weight.

"I will put the nitroglycerin patch on as soon as I get any chest pain." c. "I will stop what I am doing and sit down before I put the nitroglycerin under my tongue." d. "I will be sure to remove the nitroglycerin patch before taking any sublingual nitroglycerin."

C The patient should sit down before taking the nitroglycerin to decrease cardiac workload and prevent orthostatic hypotension. Transdermal nitrates are used prophylactically rather than to treat acute pain and can be used concurrently with sublingual nitroglycerin. Although the nurse should check blood pressure before giving nitroglycerin, patients do not need to check the pulse rate before taking nitrates.

Which one should the nurse arrange to be completed first? a. Chest x-ray b. Troponin level c. Electrocardiogram (ECG) d. Insertion of a peripheral IV

C The priority for the patient is to determine whether an acute myocardial infarction (AMI) is occurring so that reperfusion therapy can begin as quickly as possible. ECG changes occur very rapidly after coronary artery occlusion, and an ECG should be obtained as soon as possible. Troponin levels will increase after about 3 hours.

"What time did your chest pain begin?" d. "Can you rate your chest pain using a 0 to 10 scale?"

C Thrombolytic therapy should be started within 6 hours of the onset of the myocardial infarction (MI), so the time at which the chest pain started is a major determinant of the appropriateness of this treatment.

What typical sign/symptom indicates the early stage of septic shock? A. Pallor and cool skin B. Blood pressure 84/50 mm Hg C. Tachypnea and tachycardia D. Respiratory acidosis

C. Tachypnea and tachycardia Signs of systemic inflammatory response syndrome, which precedes sepsis, include rapid respiratory rate, leukocytosis, and tachycardia. In the early stage of septic shock, the client is usually warm and febrile. Hypotension does not develop until later in septic shock due to compensatory mechanisms. Respiratory alkalosis occurs early in shock because of an increased respiratory rate.

Physiological Integrity 32. A patient admitted to the coronary care unit (CCU) with an ST-segment-elevation myocardial infarction (STEMI) is restless and anxious.

Anxiety related to perceived threat of death c. Stress overload related to acute change in health d. Decreased cardiac output related to cardiogenic shock

D All the nursing diagnoses may be appropriate for this patient, but the hypotension and tachycardia indicate decreased cardiac output and shock from the damaged myocardium. This will result in decreased perfusion to all vital organs (e.g., brain, kidney, heart) and is a priority.

Physiological Integrity 11. Nadolol (Corgard) is prescribed for a patient with chronic stable angina and left ventricular dysfunction. To determine whether the drug is effective, the nurse will monitor for a. decreased blood pressure and heart rate. b. fewer complaints of having cold hands and feet. c. improvement in the strength of the distal pulses. d. the ability to do daily activities without chest pain.

D Because the medication is ordered to improve the patient's angina, effectiveness is indicated if the patient is able to accomplish daily activities without chest pain. Blood pressure and heart rate may decrease, but these data do not indicate that the goal of decreased angina has been met. The noncardioselective -adrenergic blockers can cause peripheral vasoconstriction, so the nurse would not expect an improvement in distal pulse quality or skin temperature.

The patient states that the pain has increased in frequency over the last week. d. The patient states that the pain "goes away" with one sublingual nitroglycerin tablet.

D Chronic stable angina is typically relieved by rest or nitroglycerin administration. The level of pain is not a consistent indicator of the type of angina.

D Pulse deficit is a difference between simultaneously obtained apical and radial pulses. It indicates that there may be a cardiac dysrhythmia that would best be detected with ECG monitoring. Frequent BP monitoring, cardiac catheterization, and emergent cardioversion are used for diagnosis and/or treatment of cardiovascular disorders but would not be as helpful in determining the immediate reason for the pulse deficit.

23. A hospitalized patient with heart failure has a new order for captopril (Capoten) 12.5 mg PO. After administering the first dose and teaching the patient about captopril, which statement by the patient indicates that teaching has been effective? a. "I will need to include more high-potassium foods in my diet." b. "I will expect to feel more short of breath for the next few days." c. "I will be sure to take the medication after eating something." d. "I will call for help when I need to get up to the bathroom."

D Rationale: Captopril can cause hypotension, especially after the initial dose, so it is important that the patient not get up out of bed without assistance until the nurse has had a chance to evaluate the effect of the first dose. The ACE inhibitors are potassium sparring, and the nurse should not teach the patient to increase sources of dietary potassium. Increased shortness of breath is expected with initiation of -blocker therapy for heart failure, not for ACE-inhibitor therapy. ACE inhibitors are best absorbed when taken an hour before eating.

Which laboratory test should the nurse monitor to help determine whether the patient has had an AMI? a. Myoglobin b. Homocysteine c. C-reactive protein d. Cardiac-specific troponin

D Troponin levels increase about 4 to 6 hours after the onset of myocardial infarction (MI) and are highly specific indicators for MI. Myoglobin is released within 2 hours of MI, but it lacks specificity and its use is limited. The other laboratory data are useful in determining the patient's risk for developing coronary artery disease (CAD) but are not helpful in determining whether an acute MI is in progress.

D Rationale: Indications for a heart transplant include inoperable coronary artery disease and refractory end-stage heart failure, but other factors such as coping skills, family support, and patient motivation to follow the rigorous post-transplant regimen are also considered. Heart transplants are not considered experimental; rather, transplantation has become the treatment of choice for patients who meet the criteria. The patient is not too old for a transplant.

Give the patient's other medications 2 hours after the colesevelam.

D The bile acid sequestrants interfere with the absorption of many other drugs, and giving other medications at the same time should be avoided. Taking an aspirin concurrently with the colesevelam may increase the incidence of gastrointestinal side effects such as heartburn. An increased fluid intake is encouraged for patients taking the bile acid sequestrants to reduce the risk for constipation. For maximum effect, colesevelam should be administered with meals.

Document the finding in the patient chart.

D Visible pulsation of the abdominal aorta is commonly observed in the epigastric area for thin individuals. The nurse should simply document the finding in the admission assessment.

Observe for JVD with the patient upright at 45 degrees.

D When the patient is lying flat, the jugular veins are at the level of the right atrium, so JVD is a common (but not a clinically significant) finding. Obtaining vital signs and oxygen saturation is not warranted at this point. JVD is an expected finding when a patient performs the Valsalva maneuver because right atrial pressure increases. JVD that persists when the patient is sitting at a 30- to 45-degree angle or greater is significant. The nurse will document the JVD in the medical record if it persists when the head is elevated.

An increased platelet count does not indicate sepsis; late in sepsis, platelets may decrease due to consumptive coagulopathy.

The nurse is caring for an 82-year-old client admitted for exacerbation of heart failure (HF). The nurse questions the client about the use of which medication because it raises an index of suspicion as to the worsening of the client's HF? A) Ibuprofen (Motrin) B) Hydrochlorothiazide (HydroDIURIL) C) NPH insulin D) Levothyroxine (Synthroid) (Chp. 35; elsevier)

A) Ibuprofen (Motrin) (Chp. 35; elsevier)

The nurse prepares to administer digoxin to a client with heart failure and notes the following information: Temperature: 99.8° F Pulse: 48 beats/min and irregular Respirations: 20 breaths/min Potassium level: 3.2 mEq/L What action does the nurse take? A) Give the digoxin; reassess the heart rate in 30 minutes. B) Give the digoxin; document assessment findings in the medical record. C) Hold the digoxin, and obtain a prescription for an additional dose of furosemide. D) Hold the digoxin, and obtain a prescription for a potassium supplement. (Chp. 35; elsevier)

D) Hold the digoxin, and obtain a prescription for a potassium supplement. (Chp. 35; elsevier)

6. A patient in the intensive care unit with ADHF complains of severe dyspnea and is anxious, tachypneic, and tachycardic. All these medications have been ordered for the patient. The first action by the nurse will be to a. administer IV morphine sulfate 2 mg. b. give IV diazepam (Valium) 2.5 mg. c. increase dopamine (Intropin) infusion by 2 mcg/kg/min. d. increase nitroglycerin (Tridil) infusion by 5 mcg/min.

A Rationale: Morphine improves alveolar gas exchange, improves cardiac output by reducing ventricular preload and afterload, decreases anxiety, and assists in reducing the subjective feeling of dyspnea. Diazepam may decrease patient anxiety, but it will not improve the cardiac output or gas exchange. Increasing the dopamine may improve cardiac output but will also increase the heart rate and myocardial oxygen consumption. Nitroglycerin will improve cardiac output and may be appropriate for this patient, but it will not directly reduce anxiety and will not act as quickly as morphine to decrease dyspnea.

1. A patient with a history of chronic heart failure is admitted to the emergency department with severe dyspnea and a dry, hacking cough. The patient has pitting edema in both ankles, blood pressure (BP) of 170/100, an apical pulse rate of 92, and respirations 28. The most important assessment for the nurse to accomplish next is to a. auscultate the lung sounds. b. assess the orientation. c. check the capillary refill. d. palpate the abdomen.

A Rationale: When caring for a patient with severe dyspnea, the nurse should use the ABCs to guide initial care. This patient's severe dyspnea and cough indicate that acute decompensated heart failure (ADHF) is occurring. ADHF usually manifests as pulmonary edema, which should be detected and treated immediately to prevent ongoing hypoxemia and cardiac/respiratory arrest. The other assessments will provide useful data about the patient's volume status and should also be accomplished rapidly, but detection (and treatment) of fluid-filled alveoli is the priority.

After receiving change-of-shift report about these four clients, which client should the nurse assess first? A) A 46-year-old with aortic stenosis who takes digoxin (Lanoxin) and has new-onset frequent premature ventricular contractions B) A 55-year-old admitted with pulmonary edema who received furosemide (Lasix) and whose current O2 saturation is 94% C) A 68-year-old with pericarditis who is reporting sharp, stabbing chest pain when taking deep breaths D A 79-year-old admitted for possible rejection of a heart transplant who has sinus tachycardia, heart rate 104 beats/min (Chp. 35; elsevier)

A) A 46-year-old with aortic stenosis who takes digoxin (Lanoxin) and has new-onset frequent premature ventricular contractions (Chp. 35; elsevier)

The nurse is caring for a client with heart failure. For which symptoms does the nurse assess? Select all that apply. A) Chest discomfort or pain B) Tachycardia C) Expectorating thick, yellow sputum D) Sleeping on back without a pillow E) Fatigue (Chp. 35; elsevier)

A) Chest discomfort or pain B) Tachycardia E) Fatigue (Chp. 35; elsevier)

A client who is suffering dyspnea on exertion and congestive heart failure will likely report which symptom during the health history? Fatigue Swelling of one leg Slow heart rate Brown discoloration of lower extremities

A. Although fatigue in itself is not diagnostic of heart disease, many people with heart failure are limited by leg fatigue during exercise. Fatigue that occurs after mild activity and exertion usually indicates inadequate cardiac output (due to low stroke volume) and anaerobic metabolism in skeletal muscle. Unilateral swelling is more typical with a local finding such as deep vein thrombosis, not a systemic problem such as heart failure. Tachycardia, rather than bradycardia, develops with heart failure and decreased cardiac output. Brown discoloration of the lower extremities is indicative of long-standing venous stasis, such as occurs with varicose veins.

Which client has the highest risk for cardiovascular disease? Man who smokes and whose father died at 49 of myocardial infarction (MI) Woman with abdominal obesity who exercises three times per week Woman with diabetes whose high-density lipoprotein (HDL) cholesterol is 75 mg/dL Man who is sedentary and reports four episodes of strep throat

A. Smoking is a major risk factor for MI, and family history is a stronger risk factor than hypertension, obesity, diabetes, or sudden cardiac death. Although abdominal obesity is a risk factor, exercising three times weekly is not. Diabetes is a major risk factor for MI; however, HDL cholesterol of 75 mg/dL is in the optimal range of greater than 55 mg/dL. Sedentary lifestyle is a risk factor but is not a major risk. Frequent strep infections may be associated with valvular disease rather than coronary artery disease.

Which statement reflects correct cardiac physical assessment technique? Auscultate the aortic valve in the second intercostal space at the right sternal border. Evaluate for orthostatic hypotension by moving the client from a standing to a reclining position. Palpate the apical pulse over the third intercostal space in the midclavicular line. Assess for carotid bruit by auscultating over the anterior neck.

A. The aortic valve is auscultated at the second intercostal space at the right sternal border. Orthostatic hypotension is measured when a person moves from a reclining to a standing position. The apical pulse is palpated over the fifth intercostal space in the midclavicular line. A bruit is assessed by auscultating the carotid artery in the neck.

A client is exhibiting signs and symptoms of early shock. What is important for the nurse to do to support the psychosocial integrity of the client? (Select all that apply.) A. Ask family members to stay with the client. B. Call the health care provider. C. Increase IV and oxygen rates. D. Remain with the client. E. Reassure the client that everything is being done for him or her.

A. Ask family members to stay with the client. D. Remain with the client. E. Reassure the client that everything is being done for him or her. Having a familiar person nearby may provide comfort to the client. The nurse should remain with the client who is demonstrating physiologic deterioration. Offering genuine reassurance supports the client who is anxious. The health care provider should be notified, and increasing IV and oxygen rates may be needed, but these actions do not support the client's psychosocial integrity.

A client is admitted to the hospital with two of the systemic inflammatory response syndrome variables: temperature of 95° F (35° C) and high white blood cell count. Which intervention from the sepsis resuscitation bundle does the nurse initiate? A. Broad-spectrum antibiotics B. Blood transfusion C. Cooling baths D. NPO status

A. Broad-spectrum antibiotics Broad-spectrum antibiotics must be initiated within 1 hour of establishing diagnosis. A blood transfusion is indicated for low red blood cell count or low hemoglobin and hematocrit; transfusion is not part of the sepsis resuscitation bundle. Cooling baths are not indicated because the client is hypothermic, nor is this part of the sepsis resuscitation bundle. NPO status is not indicated for this client, nor is it part of the sepsis resuscitation bundle.

The nursing assistant is concerned about a postoperative client with blood pressure (BP) of 90/60 mm Hg, heart rate of 80 beats/min, and respirations of 22 breaths/min. What does the supervising nurse do? A. Compare these vital signs with the last several readings. B. Request that the surgeon see the client. C. Increase the rate of intravenous fluids. D. Reassess vital signs using different equipment.

A. Compare these vital signs with the last several readings. Vital sign trends must be taken into consideration; a BP of 90/60 mm Hg may be normal for this client. Calling the surgeon is not necessary at this point, and increasing IV fluids is not indicated. The same equipment should be used when vital signs are taken postoperatively.

Which clinical manifestation in a client alerts the nurse to the probability of septic shock instead of hypovolemic shock? A. Hypotension B. Pale, clammy skin C. Decreased urine output D. Oozing of blood at the IV site

Answer: D Rationale: The manifestations of hypotension, pale and clammy skin, and decreased urine output are associated with any type of shock, including hypovolemic shock and septic shock. Sepsis and septic shock, however, are associated with disseminated intravascular coagulation, which consumes clotting factors and leaves the client at high risk for hemorrhage. One of the earliest manifestations of septic shock is bleeding from any area of nonintact skin, including IV insertion sites.

The client with which problem is at highest risk for hypovolemic shock? A. Esophageal varices B. Kidney failure C. Arthritis and daily acetaminophen use D. Kidney stone

A. Esophageal varices Esophageal varices are caused by portal hypertension; the portal vessels are under high pressure and are prone to rupture, causing massive upper gastrointestinal tract bleeding and hypovolemic shock. As the kidneys fail, fluid is typically retained, causing fluid volume excess, not hypovolemia. Nonsteroidal anti-inflammatory drugs such as naproxen and ibuprofen, not acetaminophen, predispose the client to gastrointestinal bleeding and hypovolemia. Although a kidney stone may cause hematuria, there is not generally massive blood loss or hypovolemia.

The client with which laboratory result is at risk for hemorrhagic shock? A. International normalized ratio (INR) 7.9 B. Partial thromboplastin time (PTT) 12.5 seconds C. Platelets 170,000/mm3 D. Hemoglobin 8.2 g/dL

A. International normalized ratio (INR) 7.9 Prolonged INR indicates that blood takes longer than normal to clot; this client is at risk for bleeding. PTT of 12.5 seconds and a platelet value of 170,000/mm3 are both normal and pose no risk for bleeding. Although a hemoglobin of 8.2 g/dL is low, the client could have severe iron deficiency or could have received medication affecting the bone marrow.

The nurse reviews the medical record of a client with hemorrhagic shock, which contains the following information: Pulse 140 beats/min and thready, ABG respiratory acidosis, Blood pressure 60/40 mm Hg, Lactate level 7 mOsm/L, Respirations 40/min and shallow. All of these provider prescriptions are given for the client. Which does the nurse carry out first? A. Notify anesthesia for endotracheal intubation. B. Give Plasmanate 1 unit now. C. Give normal saline solution 250 mL/hr. D. Type and crossmatch for 4 units of packed red blood cells (PRBCs).

A. Notify anesthesia for endotracheal intubation. Establishing an airway is the priority in all emergency situations. Although administering Plasmanate and normal saline, and typing and crossmatching for 4 units of PRBCs are important actions, airway always takes priority.

A client recovering from an open reduction of the femur suddenly feels light-headed, with increased anxiety and agitation. Which key vital sign differentiates a pulmonary embolism from early sepsis? A. Temperature B. Pulse C. Respiration D. Blood pressure

A. Temperature A sign of early sepsis is low-grade fever. Both early sepsis and thrombus may cause tachycardia, tachypnea, and hypotension.

Which clients are at immediate risk for hypovolemic shock? (Select all that apply.) A. Unrestrained client in motor vehicle accident B. Construction worker C. Athlete D. Surgical intensive care client E. 85-year-old with gastrointestinal virus

A. Unrestrained client in motor vehicle accident D. Surgical intensive care client E. 85-year-old with gastrointestinal virus The client who is unrestrained in a motor vehicle accident is prone to multiple trauma and bleeding. Surgical clients are at high risk for hypovolemic shock owing to fluid loss and hemorrhage. Older adult clients are prone to shock; a gastrointestinal virus results in fluid losses. Unless injured or working in excessive heat, the construction worker and the athlete are not at risk for hypovolemic shock; they may be at risk for dehydration.

Which laboratory findings are consistent with acute coronary syndrome (ACS)? (Select all that apply.) Troponin 3.2 ng/mL Myoglobin 234 mcg/L C-reactive protein 13 mg/dL Triglycerides 400 mg/dL Lipoprotein-a 18 mg/dL

A.B. Normal troponin should be less than 0.03 ng/mL. Normal myoglobin should be less than 90 mcg/L. Normal C-reactive protein should be less than 1 mg/dL; however, this tests for risk for coronary artery disease (CAD), not ACS. Normal triglycerides should be less than 150 mg/dL; however, this tests for risk for CAD, not ACS. Normal lipoprotein-a is 18 mg/dL; however, this tests for risk for CAD, not ACS.

The nurse is caring for a client with heart failure in the coronary care unit. The client is now exhibiting signs of air hunger and anxiety. Which nursing intervention does the nurse perform first for this client? A) Determines the client's physical limitations B) Encourages alternate rest and activity periods C) Monitors and documents heart rate, rhythm, and pulses D) Positions the client to alleviate dyspnea (Chp. 35; elsevier)

D) Positions the client to alleviate dyspnea (Chp. 35; elsevier)

Which change in laboratory value or clinical manifestations in a client with hypovolemic shock indicates to the nurse that current therapy may need to be changed? A. Urine output increases from 5 mL/hour to 6 mL/hour B. Pulse pressure decreases from 28 mm Hg to 22 mm Hg C. Serum potassium level increases from 3.6 mEq/L to 3.9 mEq/L D. Core body temperature increases from 98.2° F (36.8° C) to 98.8° F (37.1° C)

Answer: B Rationale: A compensatory response to shock is vasoconstriction. Initially, the diastolic pressure increases but systolic pressure remains the same. As a result, the difference between the systolic and diastolic pressures (pulse pressure), is smaller or "narrower." When interventions are inadequate and shock worsens, systolic pressure decreases as cardiac output decreases. This causes the pulse pressure to narrow even further, indicating that shock is progressing. Although an increase in urine output usually signals improvement, a change of 1 mL/hr is within the margin of measurement error and is meaningless in this situation.

Which manifestations of shock are a result of compensatory mechanisms to maintain circulating blood volume? A. Edema and weight gain B. Confusion and lethargy C. Decreased urine output and thirst D. Increased pulse and respiratory rates

Answer: C Rationale: Both reduced urine output and thirst are stimulated by a decreasing circulating blood volume. When people can respond to thirst by drinking, the action compensates temporarily by increasing circulating fluid volume. Decreased or absent urine output compensates by preventing a greater fluid loss. The fluid that would have been lost from the body as urine is retained. This is why hourly urine output measurements are such a sensitive indicator for whether shock is improving or progressing. Edema and weight gain are not compensations for circulating blood volume. Confusion and lethargy are responses to circulating blood volume, not compensation to improve it. Increasing pulse and respiratory rates compensate for hypoxia, not for reduced volume.

14. The nurse identifies the collaborative problem of potential complication: pulmonary edema for a patient in ADHF. When assessing the patient, the nurse will be most concerned about a. an apical pulse rate of 106 beats/min. b. an oxygen saturation of 88% on room air. c. weight gain of 1 kg (2.2 lb) over 24 hours. d. decreased hourly patient urinary output.

B Rationale: A decrease in oxygen saturation to less than 92% indicates hypoxemia. The nurse should administer supplemental oxygen immediately to the patient. An increase in apical pulse rate, 1-kg weight gain, and decreases in urine output also indicate worsening heart failure and require rapid nursing actions, but the low oxygen saturation rate requires the most immediate nursing action.

5. When the nurse is developing a teaching plan to prevent the development of heart failure in a patient with stage 1 hypertension, the information that is most likely to improve compliance with antihypertensive therapy is that a. hypertensive crisis may lead to development of acute heart failure in some patients. b. hypertension eventually will lead to heart failure by overworking the heart muscle. c. high BP increases risk for rheumatic heart disease. d. high systemic pressure precipitates papillary muscle rupture.

B Rationale: Hypertension is a primary cause of heart failure because the increase in ventricular afterload leads to ventricular hypertrophy and dilation. Hypertensive crisis may precipitate acute heart failure is some patients, but this patient with stage 1 hypertension may not be concerned about a crisis that happens only to some patients. Hypertension does not directly cause rheumatic heart disease (which is precipitated by infection with group A -hemolytic streptococcus) or papillary muscle rupture (which is caused by myocardial infarction/necrosis of the papillary muscle).

8. A patient admitted to the hospital with an exacerbation of chronic heart failure tells the nurse, "I felt fine when I went to bed, but I woke up in the middle of the night feeling like I was suffocating!" The nurse can best document this assessment information as a. pulsus alternans. b. paroxysmal nocturnal dyspnea. c. two-pillow orthopnea. d. acute bilateral pleural effusion.

B Rationale: Paroxysmal nocturnal dyspnea is caused by the reabsorption of fluid from dependent body areas when the patient is sleeping and is characterized by waking up suddenly with the feeling of suffocation. Pulsus alternans is the alternation of strong and weak peripheral pulses during palpation. Orthopnea indicates that the patient is unable to lie flat because of dyspnea. Pleural effusions develop over a longer time period. Cognitive Level: Comprehension Text Reference: p. 825 Nursing Process: Assessment NCLEX: Physiological Integrity

11. When developing a plan to decrease preload in the patient with heart failure, the nurse will include actions such as a. administering sedatives to promote rest and decrease myocardial oxygen demand. b. positioning the patient in a high-Fowler's position with the feet horizontal in the bed. c. administering oxygen per mask or nasal cannula. d. encouraging leg exercises to improve venous return.

B Rationale: Positioning the patient in a high-Fowler's position with the legs dependent will reduce preload by decreasing venous return to the right atrium. The other interventions may also be appropriate for patients with heart failure but will not help in decreasing preload. Cognitive Level: Application Text Reference: pp. 827-828 Nursing Process: Planning NCLEX: Physiological Integrity

7. Intravenous sodium nitroprusside (Nipride) is ordered for a patient with acute pulmonary edema. During the first hours of administration, the nurse will need to adjust the Nipride rate if the patient develops a. a drop in heart rate to 54 beats/min. b. a systolic BP <90 mm Hg. c. any symptoms indicating cyanide toxicity. d. an increased amount of ventricular ectopy.

B Rationale: Sodium nitroprusside is a potent vasodilator, and the major adverse effect is severe hypotension. After 48 hours of continuous use, cyanide toxicity is a possible (though rare) adverse effect. Reflex tachycardia (not bradycardia) is another adverse effect of this medication. Nitroprusside does not cause increased ventricular ectopy. Cognitive Level: Application Text Reference: p. 828 Nursing Process: Evaluation NCLEX: Physiological Integrity

10. The nurse working in the heart failure clinic will know that teaching for a 74-year-old patient with newly diagnosed heart failure has been effective when the patient a. says that the nitroglycerin patch will be used for any chest pain that develops. b. calls when the weight increases from 124 to 130 pounds in a week. c. tells the home care nurse that furosemide (Lasix) is taken daily at bedtime. d. makes an appointment to see the doctor at least once yearly.

B Rationale: Teaching for a patient with heart failure includes information about the need to weigh daily and notify the health care provider about an increase of 3 pounds in 2 days or 5 pounds in a week. Nitroglycerin patches are used primarily to reduce preload (not to prevent chest pain) in patients with heart failure and should be used daily, not on an "as necessary" basis. Diuretics should be taken earlier in the day to avoid nocturia and sleep disturbance. Heart failure is a chronic condition that will require frequent follow-up rather than an annual health care provider examination.

15. While admitting an 80-year-old patient with heart failure to the medical unit, the nurse obtains the information that the patient lives alone and sometimes confuses the "water pill" with the "heart pill." The nurse makes a note that discharge planning for the patient will need to include a. transfer to a dementia care service. b. referral to a home health care agency. c. placement in a long-term-care facility. d. arrangements for around-the-clock care.

B Rationale: The data about the patient suggest that assistance in developing a system for taking medications correctly at home is needed. A home health nurse will assess the patient's home situation and help the patient to develop a method for taking the two medications as directed. There is no evidence that the patient requires services such as dementia care, long-term-care, or around-the-clock home care.

A client who recently had a heart valve replacement is taking warfarin (Coumadin) as prescribed. What statement by the client indicates that the nurse will need to do additional health teaching? A) "I will take my pulse every day, and call my doctor if it is below 60." B) "I will eat foods that are high in vitamin K, such as kale and spinach." C) "I will weigh myself every day in the morning using the same scale." D) "I will take my blood pressure every day and call if it is too high or low." (Chp. 35; p. 697)

B) "I will eat foods that are high in vitamin K, such as kale and spinach." (Chp. 35; p. 697)

Which medication, when given in heart failure, may improve morbidity and mortality? A) Dobutamine (Dobutrex) B) Carvedilol (Coreg) C) Digoxin (Lanoxin) D) Bumetanide (Bumex) (Chp. 35; elsevier)

B) Carvedilol (Coreg) (Chp. 35; elsevier)

How does the nurse in the cardiac clinic recognize that the client with heart failure has demonstrated a positive outcome related to the addition of metoprolol (Lopressor) to the medication regimen? A) Ejection fraction is 25%. B) Client states that she is able to sleep on one pillow. C) Client was hospitalized five times last year with pulmonary edema. D) Client reports that she experiences palpitations. (Chp. 35; elsevier)

B) Client states that she is able to sleep on one pillow. (Chp. 35; elsevier)

Which client is best to assign to an LPN/LVN working on the telemetry unit? A) Client with heart failure who is receiving dobutamine (Dobutrex) B) Client with dilated cardiomyopathy who uses oxygen for exertional dyspnea C) Client with pericarditis who has a paradoxical pulse and distended jugular veins D) Client with rheumatic fever who has a new systolic murmur (Chp. 35; elsevier)

B) Client with dilated cardiomyopathy who uses oxygen for exertional dyspnea (Chp. 35; elsevier)

A client who has been admitted for the third time this year for heart failure says, "This isn't worth it anymore. I just want it all to end." What is the nurse's best response? A) Calls the family to lift the client's spirits B) Considers further assessment for depression C) Sedates the client to decrease myocardial oxygen demand D) Tells the client that things will get better (Chp. 35; elsevier)

B) Considers further assessment for depression (Chp. 35; elsevier)

A client is diagnosed with left-sided heart failure. Which assessment findings will the nurse expect the client to have? Select all that apply. A) Peripheral edema B) Crackles in both lungs C) Breathlessness D) Ascites E) Tachypnea (Chp. 35; p. 683)

B) Crackles in both lungs C) Breathlessness E) Tachypnea (Chp. 35; p. 683)

A client begins therapy with lisinopril (Prinivil, Zestril). What does the nurse consider at the start of therapy with this medication? A) The client's ability to understand medication teaching B) The risk for hypotension C) The potential for bradycardia D) Liver function tests (Chp. 35; elsevier)

B) The risk for hypotension (Chp. 35; elsevier)

The nurse plans to administer an antibiotic to a client newly admitted with septic shock. What action does the nurse take first? A. Administer the antibiotic immediately. B. Ensure that blood cultures were drawn. C. Obtain signature for informed consent. D. Take the client's vital signs.

B. Ensure that blood cultures were drawn. Cultures must be taken to identify the organism for more targeted antibiotic treatment before antibiotics are administered. Antibiotics are not administered until after all cultures are taken. A signed consent is not needed for medication administration. Monitoring the client's vital signs is important, but the antibiotic must be administered within 1 to 3 hours; timing is essential.

Which statement by the client with a recent cardiovascular diagnosis indicates maladaptive denial? "I don't know how I am going to change my lifestyle." "I don't need to change. It hasn't killed me yet." "I don't think it is as bad as the doctors say." "I will have to change my diet and exercise more."

B. A common and normal response is denial, which is a defense mechanism that enables the client to cope with threatening circumstances. He or she may deny the current cardiovascular condition, may state that it was present but is now absent, or may be excessively cheerful. Denial becomes maladaptive when the client is noncompliant or does not adhere to the interdisciplinary plan of care. The statement about not changing because "it hasn't killed me yet" indicates maladaptive denial. Not knowing how to change indicates that the client is overwhelmed, not in denial. Not thinking it is that bad indicates denial, but not maladaptive denial. Changing diet and exercising more indicates a willingness to change.

The nurse in a coronary care unit interprets information from hemodynamic monitoring. The client has a cardiac output of 2.4 L/min. Which action should be taken by the nurse? No intervention is needed; this is a normal reading. Collaborate with the health care provider to administer a positive inotropic agent. Administer a STAT dose of metoprolol (Lopressor). Ask the client to perform the Valsalva maneuver.

B. A positive inotropic agent will increase the force of contraction (stroke volume [SV]), thus increasing cardiac output (CO). Recall that SV × HR = CO (heart rate [HR]). Normal cardiac output is 4 to 7 L/min. The beta blocker metoprolol (Lopressor) has side effects of bradycardia and decreased contractility; cardiac output would be further reduced. The Valsalva maneuver, or bearing down, will decrease the heart rate and thus cardiac output.

Which statement about diagnostic cardiovascular testing is correct? Complications of coronary arteriography include stroke, nonlethal dysrhythmias, arterial bleeding, and thromboembolism. An alternative to injecting a medium into the coronary arteries is intravascular ultrasonography. Holter monitoring allows periodic recording of cardiac activity during an extended period of time. The left side of the heart is catheterized first and may be the only side examined.

B. Intravascular ultrasonography is an alternative to the medium injection method of diagnostic cardiovascular testing. Lethal, not nonlethal, dysrhythmias are a complication of diagnostic cardiovascular testing. Holter monitoring allows periodic recording of cardiac activity during short periods of time. Several parts of the heart are examined during diagnostic cardiovascular testing.

The nurse is reviewing the medical record of a client admitted with heart failure. Which laboratory result warrants a call to the health care provider by the nurse for further instructions? Calcium 8.5 mEq/L Potassium 3.0 mEq/L Magnesium 2.1 mEq/L International normalized ratio (INR) of 1.0

B. Normal potassium is 3.5 to 5.0 mEq/L; hypokalemia may predispose to dysrhythmia, especially if the client is taking digitalis preparations. A normal calcium level is 8.5 to 10.5 mEq/L. A normal magnesium level is 1.7 to 2.4 mEq/L. INR of 1.0 reflects a normal value.

Which client should the charge nurse assign to a graduate RN who has completed 2 months of orientation to the coronary care unit? Client with a new diagnosis of heart failure who needs a pulmonary artery catheter inserted Client who has just arrived after a coronary arteriogram and has vital signs requested every 15 minutes Client with acute electrocardiographic changes who is requesting nitroglycerin for left anterior chest pain Client who has many questions about the electrophysiology studies (EPS) scheduled for today

B. The client returning from angiography is stable, requiring vital signs and checks of the insertion site every 15 minutes; this is within the scope of practice of a newly licensed RN. An experienced critical care nurse is needed to assist with insertion of a pulmonary artery catheter for hemodynamic monitoring. A client with electrocardiographic changes is potentially unstable; the experienced nurse will need to monitor the electrocardiogram, administer nitroglycerin, and identify additional interventions as needed. The experienced critical care nurse needs to provide extensive teaching about the invasive procedure of EPS; the newly licensed nurse just off orientation may not have the depth of knowledge to perform this teaching independently.

A client who is to undergo cardiac catheterization should be taught which essential information by the nurse? "Monitor the pulses in your feet when you get home." "Keep your affected leg straight for 2 to 6 hours." "Do not take your blood pressure medications on the day of the procedure." "Take your oral hypoglycemic with a sip of water on the morning of the procedure."

B. The client will remain in bed and the affected leg must remain straight for 2 to 6 hours after the procedure, depending on the type of vascular closure device used, to allow the arterial puncture to heal well and prevent bleeding. The nurse monitors the pulses in the affected extremity until discharge, then teaches the client to contact the health care provider immediately if pallor, pain, paresthesia, or coolness of the extremity develops. The client may take regular medications except oral hypoglycemics. Blood pressure may be elevated due to anxiety before the procedure; therefore, antihypertensive medications are taken. Oral hypoglycemics are taken with or before meals based on an anticipated rise in glucose after eating; they are not taken when the client is NPO for procedures or surgery.

All of this information is obtained by the nurse who is admitting a client for a coronary arteriogram. Which information is most important to report to the health care provider before the procedure begins? The client has had intermittent substernal chest pain for 6 months. The client develops wheezes and dyspnea after eating crab or lobster. The client reports that a previous arteriogram was negative for coronary artery disease. The client has peripheral vascular disease, and the dorsalis pedis pulses are difficult to palpate.

B. The contrast agent injected into the coronary arteries during the arteriogram is iodine-based; the client with a shellfish allergy is likely to have an allergic reaction to the contrast and should be medicated with an antihistamine or a steroid before the procedure. The reason the client is having the procedure is to determine whether atherosclerotic plaque obstructing the coronary arteries is the underlying cause of the chest pain; the intermittent substernal chest pain does not need to be reported to the provider. The provider does not need information about the previous arteriogram at this time; it is nice to know, but does not change the current need for the procedure. The nurse will palpate the distal pulses after the procedure; they can be assessed with a Doppler device and marked in ink. Therefore, this information is not needed before the procedure is performed.

Which problem in the clients below best demonstrates the highest risk for hypovolemic shock? A. Client receiving a blood transfusion B. Client with severe ascites C. Client with myocardial infarction D. Client with syndrome of inappropriate antidiuretic hormone (SIADH) secretion

B. Client with severe ascites Fluid shifts from vascular to intra-abdominal may cause decreased circulating blood volume and poor tissue perfusion. Volume depletion is only one reason why a person may require a blood transfusion; anemia is another. The client receiving a blood transfusion does not have as high a risk as the client with severe ascites. Myocardial infarction results in tissue necrosis in the heart muscle; no blood or fluid losses occur. Owing to excess antidiuretic hormone secretion, the client with SIADH will retain fluid and therefore is not at risk for hypovolemic shock.

After a cardiac catheterization, the client should increase his or her fluid intake for which reason? NPO status will cause the client to be thirsty. The dye causes an osmotic diuresis. The dye contains a heavy sodium load. The pedal pulses will be more easily palpable.

B. The dye is osmotically heavy, causing increased urine output, possible decreased blood flow to the kidney, and renal impairment. Although the client may report thirst while NPO, the reason to increase fluids is related to osmotic diuresis from the contrast medium. The contrast medium is iodine-based. Although maintaining fluid volume may make pulses more obvious, this is not the reason to encourage fluids.

An RN and an LPN/LVN, both of whom have several years of experience in the intensive care unit, are caring for a group of clients. Which client is appropriate for the RN to assign to the LPN/LVN? A client with pulmonary edema who requires hourly monitoring of pulmonary artery wedge pressures A client who was admitted with peripheral vascular disease and needs assessment of the ankle-brachial index A client who has intermittent chest pain and requires teaching about myocardial nuclear perfusion imaging A client with acute coronary syndrome who has just been admitted and needs an admission assessment

B. The scope of practice of the LPN/LVN includes assessment of blood pressure in the arm and lower extremity. The scope of practice for the LPN/LVN does not include interpretation of hemodynamic monitoring results. The scope of practice of the RN includes providing client education; the LPN/LVN may reinforce that teaching. The role of the professional nurse is to perform assessment and develop the plan of care; the LPN/LVN may implement the plan.

Which client has pain most consistent with myocardial infarction (MI) requiring notification of the health care provider? Client with abdominal pain and belching Client with pressure in the mid-abdomen and profound diaphoresis Client with dyspnea on exertion (DOE) and inability to sleep flat who sleeps on four pillows Client with claudication and fatigue

B. Typical symptoms of MI include chest pain or pressure, ashen skin color, diaphoresis, and anxiety. Although atypical cardiac pain can be perceived in the abdomen, abdominal pain and belching are more typical of peptic ulcer. DOE and orthopnea are typical problems for clients with heart failure. Claudication (pain in the legs with exercise or at rest) is symptomatic of peripheral arterial occlusive disease.

A client with septic shock has been started on dopamine (Intropin) at 12 mcg/kg/min. Which response indicates a positive outcome? A. Hourly urine output 10 to 12 mL/hr B. Blood pressure 90/60 mm Hg and mean arterial pressure 70 mm Hg C. Blood glucose 245 mg/dL D. Serum creatinine 3.6 mg/dL

B. Blood pressure 90/60 mm Hg and mean arterial pressure 70 mm Hg Dopamine improves blood flow by increasing peripheral resistance, which increases blood pressure—a positive response in this case. Urine output less than 30 mL/hr or 0.5 mL/kg/hr and elevations in serum creatinine indicate poor tissue perfusion to the kidney and are a negative consequence of shock, not a positive response. Although a blood glucose of 245 mg/dL is an abnormal finding, dopamine increases blood pressure and myocardial contractility, not glucose levels.

How does the nurse caring for a client with septic shock recognize that severe tissue hypoxia is present? A. PaCO2 58 mm Hg B. Lactate 9.0 mmol/L C. Partial thromboplastin time 64 seconds D. Potassium 2.8 mEq/L

B. Lactate 9.0 mmol/L Poor tissue oxygenation at the cellular level causes anaerobic metabolism, with the by-product of lactic acid. Elevated partial pressure of carbon dioxide occurs with hypoventilation, which may be related to respiratory muscle fatigue, secretions, and causes other than hypoxia. Coagulation times reflect the ability of the blood to clot, not oxygenation at the cellular level. Elevation in potassium appears in septic shock due to acidosis; this value is decreased and is not consistent with septic shock.

Which clinical symptoms in a postoperative client indicate early sepsis with an excellent recovery rate if treated? A. Localized erythema and edema B. Low-grade fever and mild hypotension C. Low oxygen saturation rate and decreased cognition D. Reduced urinary output and increased respiratory rate

B. Low-grade fever and mild hypotension Low-grade fever and mild hypotension indicate very early sepsis, but with treatment, the probability of recovery is high. Localized erythema and edema indicate local infection. A low oxygen saturation rate and decreased cognition indicate active (not early) sepsis. Reduced urinary output and increased respiratory rate indicate severe sepsis.

How does the nurse recognize that a positive outcome has occurred when administering plasma protein fraction (Plasmanate)? A. Urine output 20 to 30 mL/hr for the last 4 hours B. Mean arterial pressure (MAP) 70 mm Hg C. Albumin 3.5 g/dL D. Hemoglobin 7.6 g/dL

B. Mean arterial pressure (MAP) 70 mm Hg Plasmanate expands the blood volume and helps maintain MAP greater than 65 mm Hg, which is a desired outcome in shock. Urine output should be 0.5 mL/kg/hr, or greater than 30 mL/hr. Albumin levels reflect nutritional status, which may be poor in shock states due to an increased need for calories. Plasmanate expands blood volume by exerting increasing colloid osmotic pressure in the bloodstream, pulling fluid into the vascular space; this does not improve an abnormal hemoglobin.

A postoperative client is admitted to the intensive care unit with hypovolemic shock. Which nursing action does the nurse delegate to an experienced nursing assistant? A. Obtain vital signs every 15 minutes. B. Measure hourly urine output. C. Check oxygen saturation. D. Assess level of alertness.

B. Measure hourly urine output. Monitoring hourly urine output is included in nursing assistant education and does not require special clinical judgment; the nurse evaluates the results. *Obtaining vital signs, monitoring oxygen saturation, and assessing mental status in critically ill clients requires the clinical judgment of the critical care nurse because immediate intervention may be needed*.

Which of these factors contribute to the risk for cardiovascular disease? (Select all that apply.) Consuming a diet rich in fiber Elevated C-reactive protein levels Low blood pressure Elevated high-density lipoprotein (HDL) cholesterol level Smoking

B.E. Elevation in C-reactive protein, suggestive of inflammation, is a risk factor for atherosclerosis and cardiac disease. Smoking cessation should be emphasized; smoking is a major modifiable risk factor for cardiovascular disease. A diet rich in fiber is not a risk factor for cardiovascular disease; rather, it is a desirable behavior. Hypertension, not low blood pressure, is a risk for cardiovascular disease. Elevated low-density lipoprotein cholesterol is a risk for atherosclerosis; elevated HDL cholesterol is desirable and may be cardioprotective.

The nurse is caring for a client with an arterial line. How does the nurse recognize that the client is at risk for insufficient perfusion of body organs? Right atrial pressure is 4 mm Hg. Mean arterial pressure (MAP) is 58 mm Hg. Pulmonary artery wedge pressure (PAWP) is 7 mm Hg. PO2 is reported as 78 mm Hg.

B.To maintain tissue perfusion to vital organs, the MAP must be at least 60 mm Hg. A MAP of between 60 and 70 mm Hg is necessary to maintain perfusion of major body organs such as the kidneys and brain. An arterial line will not measure atrial pressure, PAWP, or oxygenation. Normal right atrial pressure is 1 to 8 mm Hg. Normal PAWP is 4 to 12 mm Hg. A normal PO2 is greater than 75 mm Hg.

2. A patient with chronic heart failure who has been following a low-sodium diet tells the nurse at the clinic about a 5-pound weight gain in the last 3 days. The nurse's first action will be to a. ask the patient to recall the dietary intake for the last 3 days because there may be hidden sources of sodium in the patient's diet. b. instruct the patient in a low-calorie, low-fat diet because the weight gain has likely been caused by excessive intake of inappropriate foods. c. assess the patient for clinical manifestations of acute heart failure because an exacerbation of the chronic heart failure may be occurring. d. educate the patient about the use of diuretic therapy because it is likely that the patient will need medications to reduce the hypervolemia.

C Rationale: The 5-pound weight gain over 3 days indicates that the patient's chronic heart failure may be worsening; it is important that the patient be immediately assessed for other clinical manifestations of decompensation, such as lung crackles. A dietary recall to detect hidden sodium in the diet and teaching about diuretic therapy are appropriate interventions but are not the first nursing actions indicated. There is no evidence that the patient's weight gain is caused by excessive dietary intake of fat or calories, so the answer beginning "instruct the patient in a low-calorie, low-fat diet" describes an inappropriate action.

16. A home health care patient has recently started taking oral digoxin (Lanoxin) and furosemide (Lasix) for control of heart failure. The patient data that will require the most immediate action by the nurse is if the patient's a. weight increases from 120 pounds to 122 pounds over 3 days. b. liver is palpable 2 cm below the ribs on the right side. c. serum potassium level is 3.0 mEq/L after 1 week of therapy. d. has 1 to 2+ edema in the feet and ankles in the morning.

C Rationale: Hypokalemia potentiates the actions of digoxin and increases the risk for digoxin toxicity, which can cause life-threatening dysrhythmias. The other data indicate that the patient's heart failure requires more effective therapies, but they do not require nursing action as rapidly as the low serum potassium level. Cognitive Level: Application Text Reference: pp. 832-833 Nursing Process: Assessment NCLEX: Physiological Integrity

3. During assessment of a 72-year-old with ankle swelling, the nurse notes jugular venous distention (JVD) with the head of the patient's bed elevated 45 degrees. The nurse knows this finding indicates a. decreased fluid volume. b. incompetent jugular vein valves. c. elevated right atrial pressure. d. jugular vein atherosclerosis.

C Rationale: The jugular veins empty into the superior vena cava and then into the right atrium, so JVD with the patient sitting at a 45-degree angle reflects elevated right atrial pressure. JVD is an indicator of excessive fluid volume (increased preload), not decreased fluid volume; it is not caused by incompetent jugular vein valves or atherosclerosis. Cognitive Level: Comprehension Text Reference: p. 825 Nursing Process: Assessment NCLEX: Physiological Integrity

9. During a visit to an elderly patient with chronic heart failure, the home care nurse finds that the patient has severe dependent edema and that the legs appear to be weeping serous fluid. Based on these data, the best nursing diagnosis for the patient is a. activity intolerance related to venous congestion. b. disturbed body image related to massive leg swelling. c. impaired skin integrity related to peripheral edema. d. impaired gas exchange related to chronic heart failure.

C Rationale: The patient's findings of severe dependent edema and weeping serous fluid from the legs support the nursing diagnosis of impaired skin integrity. There is less evidence for the nursing diagnoses of activity intolerance, disturbed body image, and impaired gas exchange, although the nurse will further assess the patient to determine whether there are other clinical manifestations of heart failure to indicate that these diagnoses are appropriate.

The client, a college athlete who collapsed during soccer practice, has been diagnosed with hypertrophic cardiomyopathy. The client says, "This can't be. I am in great shape. I eat right and exercise." What is the nurse's best response? A) "How does this make you feel?" B) "This can be caused by taking performance-enhancing drugs." C) "This may be caused by a genetic trait." D) "Just imagine how bad it would be if you weren't in good shape." (Chp. 35; elsevier)

C) "This may be caused by a genetic trait." (Chp. 35; elsevier)

The nurse in the emergency department is caring for a client with acute heart failure who is experiencing severe dyspnea; pink, frothy sputum; and crackles throughout the lung fields. The nurse reviews the medical record, which contains the following information: Physical Assessment Findings: Crackles in all fields S3 present Oliguria Diagnostic Findings: Ejection fraction 30% BNP 560 Sodium 130 mEq/L Provider Prescriptions: Diagnosis: heart failure Enalapril 10 mg orally daily Heparin 5000 units subcutaneously every 12 hours Furosemide 40 mg IV daily Strict I & O Which prescription does the nurse implement first? A) Enalapril B) Heparin C) Furosemide D) Intake and output (I & O) (Chp. 35; elsevier)

C) Furosemide (Chp. 35; elsevier)

Which intervention best assists the client with acute pulmonary edema in reducing anxiety and dyspnea? A) Monitor pulse oximetry and cardiac rate and rhythm. B) Reassure the client that his distress can be relieved with proper intervention. C) Place the client in high-Fowler's position with the legs down. D) Ask a family member to remain with the client. (Chp. 35; elsevier)

C) Place the client in high-Fowler's position with the legs down. (Chp. 35; elsevier)

Which nursing intervention for a client admitted today with heart failure will assist the client to conserve energy? A) The client ambulates around the nursing unit with a walker. B) The nurse monitors the client's pulse and blood pressure frequently. C) The nurse obtains a bedside commode before administering furosemide. D) The nurse returns the client to bed when he becomes tachycardic. (Chp. 35; elsevier)

C) The nurse obtains a bedside commode before administering furosemide. (Chp. 35; elsevier)

When following up in the clinic with a client with heart failure, how does the nurse recognize that the client has been compliant with fluid restrictions? A) Auscultation of crackles B) Pedal edema C) Weight loss of 6 pounds since the last visit D) Reports sucking on ice chips all day for dry mouth (Chp. 35; elsevier)

C) Weight loss of 6 pounds since the last visit (Chp. 35; elsevier)

A client with heart failure reports a 7.6-pound weight gain in the past week. What intervention does the nurse anticipate from the health care provider? Dietary consult Sodium restriction Daily weight monitoring Restricted activity

C. A sudden weight increase of 2.2 pounds (1 kg) can result from excess fluid (1 L) in the interstitial spaces. The best indicator of fluid balance is weight. It is possible for weight gains of up to 10 to 15 pounds (4.5 to 6.8 kg, or 4 to 7 L of fluid) to occur before excess fluid accumulation (edema) is apparent. The weight change is most likely from excessive fluid, so a dietary consult, sodium restrictions, and restricted activity are not appropriate interventions.

Which statement best reflects correct client education for a client with a blood pressure of 136/86 mm Hg? This blood pressure is good because it is a normal reading. This blood pressure indicates that the client has hypertension or high blood pressure. This blood pressure increases the workload of the heart; the client should consider modifying his or her lifestyle. This blood pressure seems a little low; the client should be further assessed for orthostatic hypotension.

C. Although not considered hypertension because the blood pressure is not greater than 140/90 mm Hg, it is consistent with increased risk for heart disease; the client requires further education. Hypertension is defined as blood pressure greater than 140/90 mm Hg. A blood pressure that exceeds 135/85 mm Hg increases the workload of the left ventricle and oxygen consumption of the myocardium. Orthostatic hypotension is defined as blood pressure less than 90/60 mm Hg.

A client recovering from cardiac angiography develops slurred speech. What does the nurse do first? Maintains NPO (nothing by mouth) until this resolves Calls in another nurse for a second opinion Performs a complete neurologic assessment and notifies the health care provider Explains to the client and family that this is expected after sedation

C. Based on this assessment, the client probably is suffering a neurologic event, possibly a stroke. Neurologic changes such as visual disturbances, slurred speech, swallowing difficulties, and extremity weakness should be reported immediately for prompt intervention. Be confident in this decision; this assessment does not warrant a second opinion. Keeping the client NPO and waiting for symptoms to resolve is not appropriate. Slurred speech is not expected after sedation.

A 72-year-old client admitted with fatigue and dyspnea has elevated levels of all of these laboratory results. Which finding is consistent with acute coronary syndrome (ACS) and should be communicated immediately to the health care provider? White blood cell count Low-density lipoproteins Serum troponin I level C-reactive protein

C. Elevation in serum troponin levels is associated with acute myocardial injury and indicates a need for immediate interventions such as angioplasty, anticoagulant administration, or administration of fibrinolytic medications. The white blood cell count does not reflect ACS; a mild leukocytosis may occur secondary to inflammation, but this does not constitute an emergency. Although elevated lipoproteins may have contributed to development of atherosclerosis, which is the cause of ACS, the results are not emergent. C-reactive protein indicates inflammation and is increased in people at risk for atherosclerosis and ACS, but it does not indicate an acute problem.

The nurse is caring for a client in the refractory stage of cardiogenic shock. Which intervention does the nurse consider? A. Admission to rehabilitation hospital for ambulatory retraining B. Collaboration with home care agency for return to home C. Discussion with family and provider regarding palliative care D. Enrollment in a cardiac transplantation program

C. Discussion with family and provider regarding palliative care In this irreversible phase, therapy is not effective in saving the client's life, even if the cause of shock is corrected and mean arterial pressure temporarily returns to normal. A discussion on palliative care should be considered. Rehabilitation or returning home is unlikely. The client with sustained tissue hypoxia is not a candidate for organ transplantation.

Which problem places a client at highest risk for sepsis? A. Pernicious anemia B. Pericarditis C. Post kidney transplant D. Client owns an iguana

C. Post kidney transplant The post-kidney transplant client will need to take lifelong immune suppressant therapy and is at risk for infection from internal and external organisms. Pernicious anemia is related to lack of vitamin B12, not to bone marrow failure (aplastic anemia), which would place the client at risk for infection. Inflammation of the pericardial sac is an inflammatory condition that does not pose a risk for septic shock. Although owning pets, especially cats and reptiles, poses a risk for infection, the immune-suppressed kidney transplant client has a very high risk for infection, sepsis, and death.

17. Following an acute myocardial infarction, a previously healthy 67-year-old patient develops clinical manifestations of heart failure. The nurse anticipates discharge teaching will include information about a. digitalis preparations, such as digoxin (Lanoxin). b. calcium-channel blockers, such as diltiazem (Cardizem). c. -adrenergic agonists, such as dobutamine (Dobutrex). d. angiotensin-converting enzyme (ACE) inhibitors, such as captopril (Capoten).

D Rationale: ACE-inhibitor therapy is currently recommended to prevent the development of heart failure in patients who have had a myocardial infarction and as a first-line therapy for patients with chronic heart failure. Digoxin therapy for heart failure is no longer considered a first-line measure, and digoxin is added to the treatment protocol when therapy with other medications such as ACE-inhibitors, diuretics, and -adrenergic blockers is insufficient. Calcium-channel blockers are not generally used in the treatment of heart failure. The -adrenergic agonists such as dobutamine are administered through the IV route and are not used as initial therapy for heart failure.

4. The nurse is caring for a patient receiving IV furosemide (Lasix) 40 mg and enalapril (Vasotec) 5 mg PO bid for ADHF with severe orthopnea. When evaluating the patient response to the medications, the best indicator that the treatment has been effective is a. weight loss of 2 pounds overnight. b. improvement in hourly urinary output. c. reduction in systolic BP. d. decreased dyspnea with the head of the bed at 30 degrees.

D Rationale: Because the patient's major clinical manifestation of ADHF is orthopnea (caused by the presence of fluid in the alveoli), the best indicator that the medications are effective is a decrease in crackles. The other assessment data also may indicate that diuresis or improvement in cardiac output have occurred but are not as useful in evaluating this patient's response. Cognitive Level: Application Text Reference: p. 825 Nursing Process: Evaluation NCLEX: Physiological Integrity

13. The nurse plans discharge teaching for a patient with chronic heart failure who has prescriptions for digoxin (Lanoxin), hydrochlorothiazide (HydroDIURIL), and a potassium supplement. Appropriate instructions for the patient include a. avoid dietary sources of potassium because too much can cause digitalis toxicity. b. take the pulse rate daily and never take digoxin if the pulse is below 60 beats/min. c. take the hydrochlorothiazide before bedtime to maximize activity level during the day. d. notify the health care provider immediately if nausea or difficulty breathing occurs.

D Rationale: Difficulty breathing is an indication of acute decompensated heart failure and suggests that the medications are not achieving the desired effect. Nausea is an indication of digoxin toxicity and should be reported so that the provider can assess the patient for toxicity and adjust the digoxin dose, if necessary. Digoxin toxicity is potentiated by hypokalemia, rather than hyperkalemia. Patients should be taught to check their pulse daily before taking the digoxin and, if the pulse is less than 60, to call their provider before taking the digoxin. Diuretics should be taken early in the day to avoid sleep disruption. Cognitive Level: Application Text Reference: p. 835 Nursing Process: Implementation NCLEX: Health Promotion and Maintenance

12. When teaching the patient with heart failure about a 2000-mg sodium diet, the nurse explains that foods to be restricted include a. eggs and other high-cholesterol foods. b. canned and frozen fruits. c. fresh or frozen vegetables. d. milk, yogurt, and other milk products.

D Rationale: Milk and yogurt naturally contain a significant amount of sodium, and intake of these should be limited for patients on a diet that limits sodium to 2000 mg daily. Other milk products, such as processed cheeses, have very high levels of sodium and are not appropriate for a 2000-mg sodium diet. The other foods listed have minimal levels of sodium and can be eaten without restriction.

A client has been taking furosemide (Lasix) and valsartan (Diovan) for the past year. The hospital laboratory notifies the nurse that the client's serum potassium level is 6.2 mEp/L. What is the nurse's best action at this time? A) Assess the client's oxygen saturation level B) Ask the laboratory to retest the potassium level C) Give potassium as an IV infusion. D) Check the client's serum creatinine (Chp. 35; p.686)

D) Check the client's serum creatinine (Chp. 35; p. 686)

A client admitted for heart failure has a priority problem of hypervolemia related to compromised regulatory mechanisms. Which assessment result obtained the day after admission is the best indicator that the treatment has been effective? A) The client has diuresis of 400 mL in 24 hours. B) The client's blood pressure is 122/84 mm Hg. C) The client has an apical pulse of 82 beats/min. D) The client's weight decreases by 2.5 kg. (Chp. 35; elsevier)

D) The client's weight decreases by 2.5 kg. (Chp. 35; elsevier)

The nurse is teaching a client about the purpose of electrophysiology studies (EPS). Which statement by the nurse reflects the most correct teaching? "This is a noninvasive test performed to assess your heart rhythm." "You will receive an injection of dobutamine (Dobutrex) and will walk on a treadmill to reveal whether you have coronary artery disease." "This is a painless test that is done to assess the structure of your heart using sound waves." "This test evaluates you for potentially fatal cardiac rhythms."

D. EPS are invasive tests performed to determine whether the client has lethal dysrhythmias and conduction abnormalities. A noninvasive test to assess the heart rhythm best describes the electrocardiogram. Injection of dobutamine (Dobutrex) followed by walking on a treadmill best describes an exercise stress test. Using sound waves to assess the structure of the heart best describes echocardiography.

The nurse is caring for a client with hemodynamic monitoring. Right atrial pressure is 8 mm Hg. The nurse anticipates which request by the health care provider? Saline infusion Morphine sulfate No treatment, continue monitoring Intravenous furosemide

D. Normal right atrial pressure is 0 to 5 mm Hg; thus the health care provider may prescribe furosemide, a diuretic, to reduce the fluid volume and right atrial pressure. Administering saline will increase the right atrial fluid balance and pressure. Morphine is indicated to reduce preload, measured by left ventricular end-diastolic pressure or left atrial pressure. Because this is an abnormal finding, the nurse should collaborate with the provider to decrease the right atrial pressure.

The nurse is assessing a client with mitral stenosis who is to undergo a transesophageal echocardiogram (TEE) today. Which nursing action is essential? Auscultate the client's precordium for murmurs. Teach the client about the reason for the TEE. Reassure the client that the test is painless. Validate that the client has remained NPO.

D. Owing to the risk for aspiration, the client must be NPO before the procedure. It is anticipated that the client with mitral stenosis may have an audible murmur; auscultation is not essential at this time. Although teaching is important, the client could undergo the procedure without understanding the reason for the test. The client will have sedation during the test because it is uncomfortable.

A client has been admitted to the hospital with chest pain radiating down the left arm. The pain has been unrelieved by rest and antacids. Which test result best confirms that the client sustained a myocardial infarction? C-reactive protein of 1 mg/dL Homocysteine level of 13 mmol/L Creatine kinase (CK) of 125 mg/dL Troponin of 5.2 ng/mL

D. The presence of elevated troponin indicates myocardial damage; normal troponin should be less than 0.03 ng/mL. A C-reactive protein level lower than 1 mg/dL is optimal for identifying inflammation and risk for heart disease. A homocysteine level lower than 12 mmol/dL is optimal, but elevation indicates risk, not myocardial damage. CK totals must be broken down into isoenzyme MB to evaluate for heart damage. Elevations in the CK total may be caused by stroke or skeletal muscle damage.

Which action does the nurse delegate to experienced unlicensed assistive personnel (UAP) working in the cardiac catheterization laboratory? Assess preprocedure medications the client took that day. Have the client sign the consent form before the procedure is performed. Educate the client about the need to remain on bedrest after the procedure. Obtain client vital signs and a resting electrocardiogram (ECG).

D. Vital signs and 12-lead ECGs can be obtained by UAP. The health care provider will explain the catheterization procedure and have the client sign the consent form. Assessments and client teaching should be done by the RN.

The nurse is educating a group of women about the differences in symptoms of myocardial infarction (MI) in men versus those in women. Which information should be included? Men do not tend to report chest pain. Men are more likely than women to die after MI. Men more than women tend to deny the importance of symptoms. Women may experience extreme fatigue and dizziness as sole symptoms.

D. Women may have atypical symptoms, including absence of chest pain. Women often present with a "triad" of symptoms. In addition to indigestion or a feeling of abdominal fullness, chronic fatigue despite adequate rest and feeling an inability to "catch the breath" (dyspnea) are also common in heart disease. The client may also describe the sensation as aching, choking, strangling, tingling, squeezing, constricting, or vise-like. Men do report chest pain. Women have higher mortality from MI than men. Because of differences in symptoms, denial may occur more often in women.

Which problem places a person at highest risk for septic shock? A. Kidney failure B. Cirrhosis C. Lung cancer D. 40% burn injury

D. 40% burn injury The skin forms the first barrier to prevent entry of organisms into the body; this client is at very high risk for sepsis and death. Although the client with kidney failure has an increased risk for infection, his skin is intact, unlike the client with burn injury. Although the liver acts as a filter for pathogens, the client with cirrhosis has intact skin, unlike the burned client. The client with lung cancer may be at risk for increased secretions and infection, but risk is not as high as for a client with open skin.

A client with hypovolemic shock has these vital signs: temperature 97.9° F; pulse 122 beats/min; blood pressure 86/48 mm Hg; respirations 24 breaths/min; urine output 20 mL for last 2 hours; skin cool and clammy. Which medication order for this client does the nurse question? A. Dopamine (vasocontrictor) B. Dobutamine (inc cardiac contractility) C. Plasmanate (pulls water into vasc space) D. Bumetanide (diuretic)

D. Bumetanide (diuretic) A diuretic such as bumetanide will decrease blood volume in a client who is already hypovolemic; this order should be questioned because this is not an appropriate action to expand the client's blood volume. The other orders are appropriate for improving blood pressure in shock, and do not need to be questioned.

Which nurse should be assigned to care for an intubated client who has septic shock as the result of a methicillin-resistant Staphylococcus aureus (MRSA) infection? A. The LPN/LVN who has 20 years of experience B. The new RN who recently finished orienting and is working independently with moderately complex clients C. The RN who will also be caring for a client who had coronary artery bypass graft (CABG) surgery 12 hours ago D. The RN with 2 years of experience in intensive care

D. The RN with 2 years of experience in intensive care The RN with current intensive care experience who is not caring for a postoperative client would be an appropriate assignment. Care of the unstable client with intubation and mechanical ventilation is not within the scope of practice for the LPN/LVN. A client who is experiencing septic shock is too complex for the new RN. Although the RN who is also caring for the post-CABG client is experienced, this assignment will put the post-CABG client at risk for MRSA infection.

The nurse is caring for postoperative clients at risk for hypovolemic shock. Which condition represents an early symptom of shock? A. Hypotension B. Bradypnea C. Heart blocks D. Tachycardia

D. tachycardia Heart and respiratory rates increased from the client's baseline level or a slight increase in diastolic blood pressure may be the only objective manifestation of this early stage of shock. Catecholamine release occurs early in shock as a compensation for fluid loss; blood pressure will be normal. Early in shock, the client displays rapid, not slow, respirations. Dysrhythmias are a late sign of shock; they are related to lack of oxygen to the heart.
