Chapter 27: Management of Patients With Coronary Vascular Disorder - ML8

A client, who has undergone a percutaneous transluminal coronary angioplasty (PTCA), has received discharge instructions. Which statement by the client would indicate the need for further teaching by the nurse? "I should avoid taking a tub bath until my catheter site heals." "I should expect a low-grade fever and swelling at the site for the next week." "I should avoid prolonged sitting." "I should expect bruising at the catheter site for up to 3 weeks."

"I should expect a low-grade fever and swelling at the site for the next week." Fever and swelling at the site are signs of infection and should be reported to the physician. Showers should be taken until the insertion site is healed. Prolonged sitting can result in thrombosis formation. Bruising at the insertion site is common and may take from 1 to 3 weeks to resolve

A client presents to the emergency department reporting chest pain. Which order should the nurse complete first? 12-lead ECG 2 L oxygen via nasal cannula Troponin level Aspirin 325 mg orally

12-lead ECG The nurse should complete the 12-lead ECG first. The priority is to determine whether the client is suffering an acute MI and implement appropriate interventions as quickly as possible. The other orders should be completed after the ECG.

Heparin therapy is usually considered therapeutic when the client's activated partial thromboplastin time (aPTT) is how many times normal? .25 to .75 .75 to 1.5 2.0 to 2.5 2.5 to 3.0

2.0 to 2.5 The amount of heparin administered is based on aPTT results, which should be obtained during the follow-up to any alteration of dosage. The client's aPTT value would have to be greater than .25 to .75 or .75 to 1.5 times normal to be considered therapeutic. An aPTT value that is 2.5 to 3 times normal would be too high to be considered therapeutic.

The client with valvular disorder is ordered a preoperative dose of penicillin G 600,000 units to be given IV q4h. Penicillin G is supplied in a vial labeled as, "Add 4 mL diluent to yield 250,000 units per mL." How many milliliters will the nurse need to withdraw from the vial to provide the ordered dose?

2.4 600,000 units/250,000 units= 2.4 mL

A client is receiving intravenous heparin to prevent blood clots. The order is for heparin 1,200 units per hour. The pharmacy sends 25,000 units of heparin in 500 mL of D5W. At how many milliliters per hour will the nurse infuse this solution? Record your answer using a whole number.

24 (1200 units/25,000 units) X 500 mL = 24 mL.

A client asks the nurse how long to wait after taking nitroglycerin before experiencing pain relief. What is the best answer by the nurse? 3 minutes 15 minutes 30 minutes 60 minutes

3 minutes Nitroglycerin may be given by several routes: sublingual tablet or spray, oral capsule, topical agent, and intravenous (IV) administration. Sublingual nitroglycerin is generally placed under the tongue or in the cheek (buccal pouch) and ideally alleviates the pain of ischemia within 3 minutes.

A client asks the nurse how long to wait after taking nitroglycerin before experiencing pain relief. What is the best answer by the nurse? 3 minutes 15 minutes 30 minutes 60 minutes

3 minutes Nitroglycerin may be given by several routes: sublingual tablet or spray, oral capsule, topical agent, and intravenous (IV) administration. Sublingual nitroglycerin is generally placed under the tongue or in the cheek (buccal pouch) and ideally alleviates the pain of ischemia within 3 minutes.

The nurse has just admitted a 66-year-old patient for cardiac surgery. The patient tells the nurse that she is afraid of dying while undergoing the surgery. The nurse should be aware that: A further assessment of anxiety is required. A more complete physical examination is required. Preoperative fears are normal and will be alleviated with time. Teaching should be initiated immediately to alleviate the fears.

A further assessment of anxiety is required. An assessment of anxiety levels is required in the patient to assist in identifying fears and developing coping mechanisms for those fears. If anxiety is high, it may interfere with teaching, and surgical outcome is poor. Nothing in the scenario suggests that a more complete physical examination is required. Further assessment should precede teaching. Preoperative fears are normal, but they should not be ignored and will not necessarily abate on their own.

Which assessment finding by the nurse is the most significant finding suggestive of aortic aneurysm? High blood pressure Severe back pain Abdomen bruit Nausea and vomiting

Abdomen bruit A pulsating mass or a bruit in the abdomen over the mass is most suggestive of aortic aneurysm. Severe back pain, nausea, and high blood pressure are all symptoms associated with aortic aneurysm but not as independently suggestive.

A nurse is reevaluating a client receiving IV fibrinolytic therapy. Which finding requires immediate intervention by the nurse? Altered level of consciousness Minimal oozing of blood from the IV site Presence of reperfusion dysrhythmias Chest pain 2 of 10 (on a 1-to-10 pain scale)

Altered level of consciousness A client receiving fibrinolytic therapy is at risk for complications associated with bleeding. Altered level of consciousness may indicate hypoxia and intracranial bleeding, and the infusion should be discontinued immediately. Minimal bleeding requires manual pressure. Reperfusion dysrhythmias are an expected finding. A chest pain score of 2 is low and indicates the client's chest pain is subsiding, an expected outcome of this therapy.

A client has recently undergone a coronary artery bypass graft (CABG). The nurse should be alert to which respiratory complication? Atelectasis Elevated blood glucose level Hyperkalemia Urinary tract infection (UTI)

Atelectasis Respiratory complications that may occur include atelectasis. An incentive spirometer and the use of deep breathing exercises are necessary to prevent atelectasis and pneumonia. Elevated blood sugar levels, hyperkalemia, UTI, and are complications that can occur but are unrelated to the respiratory system.

The nurse administers propranolol hydrochloride to a patient with a heart rate of 64 beats per minute (bpm). One hour later, the nurse observes the heart rate on the monitor to be 36 bpm. What medication should the nurse prepare to administer that is an antidote for the propranolol? Digoxin Atropine Protamine sulfate Sodium nitroprusside

Atropine Sheath removal and the application of pressure on the vessel insertion site may cause the heart rate to slow and the blood pressure to decrease (vasovagal response). A dose of IV atropine is usually given to treat this response.

The nursing instructor is teaching the junior nursing students about aortic regurgitation. What classification of drugs are used to treat aortic regurgitation? Antihypertensives Anticoagulants Cardiac glycosides Anti-arrhythmics

Cardiac glycosides Because aortic regurgitation is mild and only slowly progressive in most people, clients are sustained with cardiac glycosides or beta blockers and diuretics. Antihypertensives, anticoagulants, and anti-arrhythmics are not the type of drugs used to treat aortic regurgitation.

Which complication of cardiac surgery occurs when fluid and clots accumulate in the pericardial sac, which compresses the heart, preventing blood from filling the ventricles? Cardiac tamponade Fluid overload Hypertension Hypothermia

Cardiac tamponade Cardiac tamponade is fluid and clot accumulation in the pericardial sac, which compresses the heart, preventing the blood from filling the ventricles. Fluid overload is exhibited by high pulmonary artery wedge pressure, central venous pressure, and pulmonary artery diastolic pressure, as well as crackles in the lungs. Hypertension results from postoperative vasoconstriction. Hypothermia is a low body temperature that leads to vasoconstriction.

A patient has had cardiac surgery and is being monitored in the intensive care unit (ICU). What complication should the nurse monitor for that is associated with an alteration in preload? Cardiac tamponade Elevated central venous pressure Hypertension Hypothermia

Cardiac tamponade Preload alterations occur when too little blood volume returns to the heart as a result of persistent bleeding and hypovolemia. Excessive postoperative bleeding can lead to decreased intravascular volume, hypotension, and low cardiac output. Bleeding problems are common after cardiac surgery because of the effects of cardiopulmonary bypass, trauma from the surgery, and anticoagulation. Preload can also decrease if there is a collection of fluid and blood in the pericardium (cardiac tamponade), which impedes cardiac filling. Cardiac output is also altered if too much volume returns to the heart, causing fluid overload.

The nurse is assisting with a bronchoscopy at the bedside in a critical care unit. The client experiences a vasovagal response. What should the nurse do next? Prepare to administer intravenous fluids. Suction the airway. Check blood pressure. Assess pupils for reactiveness.

Check blood pressure. During a bronchoscopy, a vasovagal response may be caused by stimulating the pharynx, and it in turn may cause stimulation of the vagus nerve. The client may, therefore, experience a sudden drop in heart rate, leading to syncope. The nurse will need to assess blood pressure to assure circulation. Stimulation of the vagus nerve doesn't lead to pupillary dilation or bronchodilation. Stimulation of the vagus nerve increases gastric secretions.

A client had a percutaneous transluminal coronary angioplasty (PTCA). What medication will the nurse administer to prevent thrombus formation in the stent? Clopidogrel Isosorbide mononitrate Metoprolol Diltiazem

Clopidogrel Because of the risk of thrombus formation following a coronary stent placement, the patient receives antiplatelet medications, such as clopidogrel or aspirin. Isosorbide mononitrate is a nitrate used for vasodilation. Metoprolol is a beta blocker used for relaxing blood vessels and slowing heart rate. Diltiazem is a calcium channel blocker used to relax heart muscles and blood vessels.

Which medication is given to clients who are diagnosed with angina but are allergic to aspirin? Clopidogrel Amlodipine Diltiazem Felodipine

Clopidogrel Clopidogrel or ticlopidine is given to clients who are allergic to aspirin or are given in addition to aspirin to clients who are at high risk for MI. Amlodipine, diltiazem, and felodipine are calcium channel blockers.

A client is admitted for treatment of Prinzmetal's angina. When developing this client's care plan, the nurse should keep in mind that this type of angina is a result of what trigger? Activities that increase myocardial oxygen demand. An unpredictable amount of activity. Coronary artery spasm. The same type of activity that caused previous angina episodes.

Coronary artery spasm. Prinzmetal's angina results from coronary artery spasm. Activities that increase myocardial oxygen demand may trigger angina of effort. An unpredictable amount of activity may precipitate unstable angina. Worsening angina is brought on by the same type or level of activity that caused previous angina episodes; anginal pain becomes increasingly severe.

The nurse is reviewing the laboratory results for a patient having a suspected myocardial infarction (MI). What cardiac-specific isoenzyme does the nurse observe for myocardial cell damage? Alkaline phosphatase Creatine kinase MB Myoglobin Troponin

Creatine kinase MB There are three creatine kinase (CK) isoenzymes: CK-MM (skeletal muscle), CK-MB (heart muscle), and CK-BB (brain tissue). CK-MB is the cardiac-specific isoenzyme; it is found mainly in cardiac cells and therefore increases when there has been damage to these cells. Elevated CK-MB is an indicator of acute MI; the level begins to increase within a few hours and peaks within 24 hours of an infarct.

The nurse is caring for a client who was admitted to the telemetry unit with a diagnosis of "rule/out acute MI." The client's chest pain began 3 hours earlier. Which laboratory test would be most helpful in confirming the diagnosis of a current MI? Creatinine kinase-myoglobin (CK-MB) level Troponin C level Myoglobin level CK-MM

Creatinine kinase-myoglobin (CK-MB) level Elevated CK-MB assessment by mass assay is an indicator of acute MI; the levels begin to increase within a few hours and peak within 24 hours of an MI. If the area is reperfused (as a result of thrombotic therapy or PCI), it peaks earlier. CK-MM (skeletal muscle) is not an indicator of cardiac muscle damage. Three isomers of troponin exist: C, I, and T. Troponins I and T are specific for cardiac muscle, and these biomarkers are currently recognized as reliable and critical markers of myocardial injury. An increase in myoglobin is not very specific in indicating an acute cardiac event; however, negative results are an excellent parameter for ruling out an acute MI.

A nurse records a client's history and discovers several risk factors for coronary artery disease (CAD). Which cardiac risk factors can the client control? Diabetes, hypercholesterolemia, and heredity Diabetes, age, and gender Age, gender, and heredity Diabetes, hypercholesterolemia, and hypertension

Diabetes, hypercholesterolemia, and hypertension Controllable risk factors for CAD include hypertension, hypercholesterolemia, obesity, lack of exercise, smoking, diabetes mellitus, stress, alcohol abuse, and use of hormonal contraceptives. Uncontrollable risk factors for CAD include gender, age, and heredity.

In providing nursing management to a client post-varicose vein surgery, the nurse would include which of the following teaching measures? Select all that apply. Exercise Cool compresses Elastic stockings Lower the extremities. Stand rather than sit. Take warm showers in the morning.

Exercise Elastic stockings Movement/exercise and use of elastic stocking aid in venous return. Cool compresses can cause vasoconstriction, which can diminish arterial blood flow. Elevation of legs can be helpful in aiding venous return. Standing or sitting for prolonged periods of time should be avoided. Showers in the morning can dilate blood vessels and contribute to venous congestion and edema.

The nurse is administering oral metoprolol. Where are the receptor sites mainly located? Uterus Blood vessels Bronchi Heart

Heart Metoprolol works at beta 1 -receptor sites. Most beta1-receptor sites are located in the heart. Beta2-receptor sites are located in the uterus, blood vessels, and bronchi.

Which is a modifiable risk factor for coronary artery disease (CAD)? Increasing age Hyperlipidemia Male gender Family history

Hyperlipidemia Other modifiable risk factors for CAD include tobacco use, hypertension, diabetes, metabolic syndrome, obesity, and physical inactivity. Increasing age, male gender, and family history are nonmodifiable risk factors for CAD.

Understanding atherosclerosis, the nurse identifies which of the following to be both a risk factor for the development of the disorder and an outcome? Hyperlipidemia Hypertension Glucose intolerance Obesity

Hypertension Increases in diastolic and systolic blood pressure are associated with an increased incidence of atherosclerosis, often an inherited factor. Elevation of blood pressure results when the vessels cannot relax and impairs the ability of the artery to dilate. Hyperlipidemia, diabetes, and obesity are all risk factors for atherosclerosis but do not result from the disorder.

A client with venous insufficiency is instructed to exercise, apply elastic stockings, and elevate the extremities. Which is the primary benefit for this nursing management regime? Improve arterial flow Strengthen venous valves Increase venous congestion Improve venous return

Improve venous return The major goal in management of venous insufficiency is to promote venous circulation. Arterial flow improvement is not the goal of treatment for this disorder. Venous valves that are incompetent cannot be strengthened. Venous congestion is a complication of venous insufficiency.

A client diagnosed with a myocardial infarction (MI) has begun an active rehabilitation program. The nurse recognizes which overall goal as a focus of rehabilitation for a client who has had an MI? Improved quality of life Limit to the effects and progression of atherosclerosis Return to work and the lifestyle experienced before the illness Prevention of another cardiac event

Improved quality of life Overall, cardiac rehabilitation is a complete program dedicated to extending and improving quality of life. Immediate objectives of rehabilitation of the client with an MI is to limit the effects and progression of atherosclerosis, to return the client to work and their preillness lifestyle, and to prevent another cardiac event.

A client has been recently placed on nitroglycerin. Which instruction by the nurse should be included in the client's teaching plan? Instruct the client on side effects of flushing, throbbing headache, and tachycardia. Instruct the client to renew the nitroglycerin supply every 3 months. Instruct the client not to crush the tablet. Instruct the client to place nitroglycerin tablets in a plastic pill box.

Instruct the client on side effects of flushing, throbbing headache, and tachycardia. The client should be instructed about side effects of the medication, which include flushing, throbbing headache, and tachycardia. The client should renew the nitroglycerin supply every 6 months. If the pain is severe, the client can crush the tablet between the teeth to hasten sublingual absorption. Tablets should never be removed and stored in metal or plastic pillboxes. Nitroglycerin is very unstable and should be carried in its original container.

After 2-hour onset of acute chest pain, the client is brought to the emergency department for evaluation. Elevation of which diagnostic findings would the nurse identify as suggestive of an acute myocardial infarction at this time? Troponin I Myoglobin WBC (white blood cell) count C-reactive protein

Myoglobin Myoglobin is a biomarker that rises in 2 to 3 hours after heart damage. Troponin is the gold standard for determining heart damage, but troponin I levels due not rise until 4 to 6 hours after MI. WBCs and C-reactive protein levels will rise but not until about day 3.

The nurse is caring for a client who is being evaluated for lipid-lowering medication. The client's laboratory results reveal the following: total cholesterol 230 mg/dL, LDL 120 mg/dL, triglyceride level 310 mg/dL. Which class of medications would be mostappropriate for the client based on these laboratory findings? Nicotinic acid Fibric acid Bile acid sequestrant HMG-CoA reductase inhibitor

Nicotinic acid The most appropriate class of medications based on the client's laboratory findings would be nicotinic acid. This class of medications is prescribed for clients with minimally elevated cholesterol and LDL levels or as an adjunct to a statin when the lipid goal has not been has not been achieved and triglyceride levels are elevated.

A client with Raynaud's disease complains of cold and numbness in the fingers. Which of the following would the nurse identify as an early sign of vasoconstriction? Cyanosis Gangrene Pallor Clubbing of the fingers

Pallor Pallor is the initial symptom in Raynaud's followed by cyanosis and aching pain. Gangrene can occur with persistent attacks and interference of blood flow. Clubbing of the fingers is a symptom associated with chronic oxygen deprivation to the distal phalanges.

A client with CAD has been prescribed a transdermal nitroglycerin patch. What instructions should the nurse provide to to the client? Select all that apply. Remove the transdermal patch at night and reapply in the morning. Store the patch in its original container when not in use. Cover the patch in plastic wrap after applying. Seek emergency treatment if flushing or nausea occurs.

Remove the transdermal patch at night and reapply in the morning. Store the patch in its original container when not in use. Transdermal nitroglycerin systems are applied to the skin and slowly release nitroglycerin. Clients should be instructed to store the patch in its original container when not in use and keep tightly closed, remove the patch each night and reapply in the morning to prevent diminishing vasodilating effects, and expect possible side effects, such as headache, flushing, or nausea.

The client is prescribed nadolol for hypertension. What is the reason the nurse will teach the client not to stop taking the medication abruptly? The abrupt stop can cause a myocardial infarction. The abrupt stop can lead to formation of blood clots. The abrupt stop will precipitate internal bleeding. The abrupt stop can trigger a migraine headache.

The abrupt stop can cause a myocardial infarction. Patients taking beta blockers are cautioned not to stop taking them abruptly because angina may worsen and myocardial infarction may develop. Beta blockers do not cause the formation of blood clots, internal bleeding, or the onset of a migraine headache.

A nurse is evaluating a client who had a myocardial infarction (MI) 7 days earlier. Which outcome indicates that the client is responding favorably to therapy? The client demonstrates ability to tolerate more activity without chest pain. The client exhibits a heart rate above 100 beats/minute. The client verbalizes the intention of making all necessary lifestyle changes except for stopping smoking. The client states that sublingual nitroglycerin usually relieves his chest pain.

The client demonstrates ability to tolerate more activity without chest pain. The ability to tolerate more activity without chest pain indicates a favorable response to therapy in a client who is recovering from an MI or who has a history of coronary artery disease. The client should have a normal electrocardiogram with no arrhythmias and a regular heart rate of 60 to 100 beats/minute. Smoking is a cardiovascular risk factor that the client must be willing to eliminate. A client who responds favorably to therapy shouldn't have chest pain.

Two female nursing assistants approach a nurse on a cardiac step-down unit to report that a client who experienced an acute myocardial infarction made sexual comments to them. How should the nurse intervene? The nurse should explain that the client might have concerns about resuming sexual activity but is afraid to ask. The nurse should report the incident to her supervisor immediately. The nurse should instruct the nursing assistants to avoid answering his call light. The nurse should explain that the client most likely wants extra attention.

The nurse should explain that the client might have concerns about resuming sexual activity but is afraid to ask. Sometimes clients are concerned about resuming sexual activity but are afraid to ask. Making inappropriate sexual comments provides a forum for asking questions. It isn't necessary to report the incident to the nursing supervisor immediately without investigating the situation further. The client's call light must be answered in a timely fashion. More information is needed before assuming that the client is asking for extra attention.

A patient with coronary artery disease (CAD) is having a cardiac catheterization. What indicator is present for the patient to have a coronary artery bypass graft (CABG)? The patient has compromised left ventricular function. The patient has had angina longer than 3 years. The patient has at least a 70% occlusion of a major coronary artery. The patient has an ejection fraction of 65%.

The patient has at least a 70% occlusion of a major coronary artery. For a patient to be considered for CABG, the coronary arteries to be bypassed must have approximately a 70% occlusion (60% if in the left main coronary artery).

Which nursing actions would be of greatest importance in the management of a client preparing for angioplasty? Inform client of diagnostic tests. Remove hair from skin insertion sites. Assess distal pulses. Withhold anticoagulant therapy.

Withhold anticoagulant therapy. The nurse knows to withhold the anticoagulant therapy to decrease chance of hemorrhage during the procedure. The nurse does inform the client of diagnostic test, will assess pulses, and prep the skin prior to the angioplasty, but this is not the most important action to be taken.

A client has had a 12-lead ECG completed as part of an annual physical examination. The nurse notes an abnormal Q wave on an otherwise unremarkable ECG. The nurse recognizes that this finding indicates an old MI. an evolving MI. variant angina. a cardiac dysrhythmia.

an old MI. An abnormal Q wave may be present without ST-segment and T-wave changes, which indicates an old, not acute, MI.

A client reports pain and cramping in the thigh when climbing stairs and numbness in the legs after exertion. Which diagnostic test with the physician likely perform right in the office to determine PAD? ankle-brachial index exercise electrocardiography electron beam computed tomography photoplethysmography

ankle-brachial index The client's symptoms indicate possible peripheral artery disease (PAD). The ankle-brachial index is a simple, noninvasive test used for this diagnosis. An exercise electrocardiography may be ordered for a client with possible CAD. An EBCT is a radiologic test that produces x-rays of the coronary arteries using an electron beam. It is used to diagnose for CAD. Clients with suspected venous insufficiency will undergo photoplethysmography, a diagnostic test that measures light that is not absorbed by hemoglobin and consequently is reflected back to the machine.

A client with a myocardial infarction (MI) develops pulmonary crackles and dyspnea. A chest X-ray shows evidence of pulmonary edema. What type of MI did this client have? anterior. posterior. lateral. inferior.

anterior. An anterior MI causes left ventricular dysfunction and can lead to manifestations of heart failure, which include pulmonary crackles and dyspnea. Posterior, lateral, and inferior MI aren't usually associated with heart failure.

A client with CAD thinks diltiazem (Cardizem) has been causing nausea. Diltiazem (Cardizem) is categorized as which type of drug? calcium-channel blocker beta-adrenergic blocker nitrate diuretic

calcium-channel blocker Calcium-channel blocking agents may be used to treat CAD as well, although research has shown that they may be less beneficial than beta-adrenergic blocking agents. Diltiazem (Cardizem) is an example of a calcium-channel blocker.

A client who has been diagnosed with Prinzmetal's angina will present with which symptom? chest pain that occurs at rest and usually in the middle of the night radiating chest pain that lasts 15 minutes or less prolonged chest pain that accompanies exercise chest pain of increased frequency, severity, and duration

chest pain that occurs at rest and usually in the middle of the night A client with Prinzmetal's angina will complain of chest pain that occurs at rest, usually between 12 and 8:00 AM, is sporadic over 3-6 months, and diminishes over time. Clients with stable angina generally experience chest pain that lasts 15 minutes or less and may radiate. Clients with Cardiac Syndrome X experience prolonged chest pain that accompanies exercise and is not always relieved by medication. Clients with unstable angina experience chest pain of increased frequency, severity, and duration that is poorly relieved by rest or oral nitrates.

What is a modifiable risk factor for the development of atherosclerosis? consumption of a high-fat diet prior infection with Chlamydia pneumoniae gender history of rheumatic fever

consumption of a high-fat diet There are many known risk factors for development of atherosclerosis. Factors that are modifiable, or that a client can change, include diet, activity level, and smoking cessation. Some that are nonmodifiable include gender, heredity, certain diseases, and history of infection with Chlamydia pneumoniae. These factors individually or collectively contribute to hyperlipidemia, which then triggers atherosclerotic changes.

The nurse is caring for a client with coronary artery disease. What is the nurse's priority goal for the client? decrease anxiety enhance myocardial oxygenation administer sublingual nitroglycerin educate the client about his symptoms

enhance myocardial oxygenation Enhancing myocardial oxygenation is always the first priority when a client exhibits signs or symptoms of cardiac compromise. Without adequate oxygen, the myocardium suffers damage. A nurse administers sublingual nitroglycerin to treat acute angina pectoris, but its administration isn't the first priority. Although educating the client and decreasing anxiety are important in care, neither is a priority when a client is compromised.

Immediately following administering a medication by enteral tube, the nurse will: flush the tube with water. position the child on his left side. elevate the head of the bed. check for signs of nausea or vomiting.

flush the tube with water. It is important to flush the tube to ensure all of the medication reaches the child's digestive tract and to prevent occlusion of the tube. Right (not left) side-lying position will aid in stomach emptying, although it was not specified that the enteral tube was located in the stomach. Elevating the head of the bed is done prior to placing material in the gastrointestinal tract. Checking for signs of nausea and vomiting is always important but not the immediately following nursing action in this situation.

A client's lipid profile reveals an LDL level of 122 mg/dL. This is considered a: high LDL level. low LDL level. normal LDL level. fasting LDL level.

high LDL level. LDL levels above 100 mg/dL are considered high. The goal is to decrease the LDL level below 100 mg/dL.

The laboratory values for a client diagnosed with coronary artery disease (CAD) have just come back from the lab. The client's low-density lipoprotein (LDL) level is 112 mg/dL. This nurses recognizes that this value is low. high. normal. extremely high.

high. If the LDL level ranges from 100 mg/dL to 130 mg/dL, it is considered to be high. The goal is to decrease the LDL level below 100 mg/dL.

The nurse is reviewing the laboratory results for a client diagnosed with coronary artery disease (CAD). The client's low-density lipoprotein (LDL) level is 115 mg/dL. The nurse interprets this value as high. low. within normal limits. critically high.

high. The normal LDL range is 100 to 130 mg/dL. A level of 115 mg/dL is considered to be high. The goal of treatment is to decrease the LDL level below 100 mg/dL (less than 70 mg/dL for very high-risk clients).

A client's elevated cholesterol levels are being managed with atorvastatin daily. What is a common side effect the nurse will teach the client that will require monitoring? hyperuricemia increased liver enzymes hyperglycemia severe muscle pain

increased liver enzymes Myopathy and increased liver enzymes are significant side effects of the statin Lipitor. Hyperuricemia occurs when too much uric acid is present in the blood; it is not a side effect of the statins. Hyperglycemia is increased blood glucose, which is not a side effect of the statins. Severe muscle pain is an adverse effect of statins, but it does not require monitoring.

A nurse completed a client physical examination for an insurance company. The nurse determined the client has increased blood pressure, increased blood glucose, levels and obesity. What condition for coronary artery disease does the nurse consider next? congestive heart failure hypolipidemia metabolic syndrome diabetes mellitus

metabolic syndrome Metabolic syndrome includes three of six conditions that are recognized as major risk factors for CAD. Insulin resistance is part of the syndrome, but the patient may not yet have diabetes.

The nurse recognizes that the treatment for a non-ST-elevation myocardial infarction (NSTEMI) differs from that for a STEMI, in that a STEMI is more frequently treated with percutaneous coronary intervention (PCI). IV heparin. IV nitroglycerin. thrombolytics.

percutaneous coronary intervention (PCI). The client with a STEMI is often taken directly to the cardiac catheterization laboratory for an immediate PCI. Superior outcomes have been reported with the use of PCI compared to thrombolytics. IV heparin and IV nitroglycerin are used to treat NSTEMI.

The nurse is caring for a client after cardiac surgery. What is the most immediate concern for the nurse? weight gain of 6 ounces serum glucose of 124 mg/dL potassium level of 6 mEq/L bilateral rales and rhonchi

potassium level of 6 mEq/L Changes in serum electrolytes should be immediately reported, especially a potassium level of 6 mEq/L. An elevated blood sugar is common postoperatively, and the weight gain is not significant. The abnormal breath sounds are of concern, but the electrolyte imbalance is the most immediate condition that needs to be addressed.

A client was transferring a load of firewood in the morning and experienced a heaviness in the chest and dyspnea. The client arrives in the emergency department four hours after the heaviness and the health care provider diagnoses an anterior myocardial infarction (MI). What orders will the nurse anticipate? streptokinase, aspirin, and morphine administration morphine administration, stress testing, and admission to the cardiac care unit serial liver enzyme testing, telemetry, and a lidocaine infusion sublingual nitroglycerin, tissue plasminogen activator (tPA), and telemetry

sublingual nitroglycerin, tissue plasminogen activator (tPA), and telemetry The nurse should anticipate an order for sublingual nitroglycerin, tPA, and telemetry, as the client's chest pain began 4 hours before diagnosis. The preferred choice is tPA, which is more specific for cardiac tissue than streptokinase. Stress testing shouldn't be performed during an MI. The client doesn't exhibit symptoms that indicate the use of lidocaine.

A client is receiving morphine to relieve chest pain. The order is for 4 mg IV now. The pharmacy supplies morphine sulfate at 5 mg per mL. How many mL will the nurse give the client? Enter the correct number ONLY.

0.8 (4 mg/5 mg) X 1 mL = 0.8 mL.

A client with a family history of coronary artery disease reports experiencing chest pain and palpitations during and after morning jogs. What would reduce the client's cardiac risk? smoking cessation a protein-rich diet exercise avoidance antioxidant supplements

smoking cessation The first line of defense for clients with CAD is lifestyle changes including smoking cessation, weight loss, stress management, and exercise. Clients with CAD should eat a balanced diet. Clients with CAD should exercise, as tolerated, to maintain a healthy weight. Antioxidant supplements, such as those containing vitamin E, beta carotene, and selenium, are not recommended because clinical trials have failed to confirm beneficial effects from their use.

A client with known coronary artery disease reports intermittent chest pain, usually on exertion. When teaching the client about nitroglycerin administration, which instruction should the nurse provide? "Be sure to take safety precautions because nitroglycerin may cause dizziness when you stand up." "Replace leftover sublingual nitroglycerin tablets every 9 months to make sure your pills are fresh." "A burning sensation after administration indicates that the nitroglycerin tablets are potent." "You may take a sublingual nitroglycerin tablet every 30 minutes, if needed. You may take as many as four doses."

"Be sure to take safety precautions because nitroglycerin may cause dizziness when you stand up." Nitroglycerin commonly causes orthostatic hypotension and dizziness. To minimize these problems, the nurse should teach the client to take safety precautions, such as changing to an upright position slowly, climbing up and down stairs carefully, and lying down at the first sign of dizziness. To ensure the freshness of sublingual nitroglycerin, the client should replace tablets every 6 months, not every 9 months, and store them in a tightly closed container in a cool, dark place. Many brands of sublingual nitroglycerin no longer produce a burning sensation. The client should take a sublingual nitroglycerin tablet at the first sign of angina. He may repeat the dose every 5 minutes for up to three doses; if this intervention doesn't bring relief, the client should seek immediate medical attention.

A client comes to the health care provider's office for a follow-up visit 4 weeks after suffering a myocardial infarction (MI). Which evaluation statement suggests that the client needs more instruction? "Client performs relaxation exercises three times per day to reduce stress." "Client's 24-hour dietary recall reveals low intake of fat and cholesterol." "Client verbalizes an understanding of the need to seek emergency help if heart rate increases markedly while at rest." "Client walks 4 miles in 1 hour every day."

"Client walks 4 miles in 1 hour every day." Four weeks after an MI, a client's walking program should aim for a goal of 2 miles in less than 1 hour. Walking 4 miles in 1 hour is excessive and may induce another MI by increasing the heart's oxygen demands. Therefore, this client requires appropriate exercise guidelines and precautions. Performing relaxation exercises, following a low-fat, low-cholesterol diet, and seeking emergency help if the heart rate increases markedly at rest indicate understanding of the cardiac rehabilitation program. For example, the client should reduce stress, which speeds the heart rate and thus increases myocardial oxygen demands. Reducing dietary fat and cholesterol intake helps lower risk of atherosclerosis. A sudden rise in the heart rate while at rest warrants emergency medical attention because it may signal a life-threatening arrhythmia and increase myocardial oxygen demands.

A client with angina pectoris must learn how to reduce risk factors that exacerbate this condition. When developing the client's care plan, which expected outcome should a nurse include? "Client will verbalize an understanding of the need to call the physician if acute pain lasts more than 2 hours." "Client will verbalize the intention to avoid exercise." "Client will verbalize the intention to stop smoking." "Client will verbalize an understanding of the need to restrict dietary fat, fiber, and cholesterol."

"Client will verbalize the intention to stop smoking." A client with angina pectoris should stop smoking at once because smoking increases the blood carboxyhemoglobin level; this increase, in turn, reduces the heart's oxygen supply and may induce angina. The client must seek immediate medical attention if chest pain doesn't subside after three nitroglycerin doses taken 5 minutes apart; serious myocardial damage or even sudden death may occur if chest pain persists for 2 hours. To improve coronary circulation and promote weight management, the client should get regular daily exercise. The client should eat plenty of fiber, which may decrease serum cholesterol and triglyceride levels and minimize hypertension, in turn reducing the risk for atherosclerosis (which plays a role in angina).

A nurse who works in a busy emergency department provides care for numerous patients who present with complaints of chest pain. Which of the following questions is most likely to help the nurse differentiate between chest pain that is attributable to angina and chest pain due to myocardial infarction (MI)? "Does resting and remaining still help your chest pain to decrease?" "Have you ever been diagnosed with high blood pressure or diabetes?" "When was the first time that you recall having chest pain?" "Does your chest pain make it difficult to move around like you normally would?"

"Does resting and remaining still help your chest pain to decrease?" In most cases, chest pain due to MI is not relieved by rest. Chest pain from angina usually abates with rest. Questions about risk factors or the original onset of the patient's pain do not help differentiate the etiology of a patient's chest pain.

A child is undergoing a painful procedure and is upset. Which statement by the nurse would be the best approach in dealing with the child? "If you hold still and be quiet, I will give you a Popsicle." "You were brave and good, so you get a sucker." "I know that this hurts some but you are being so strong. It is OK to cry." "Please don't bite or kick me; that would be very naughty."

"I know that this hurts some but you are being so strong. It is OK to cry." Children should be given the right to cry and be verbally praised for cooperating. Pediatric patients should not routinely be rewarded for acting appropriately during a procedure or for being brave or good, but if they are given a small reward such as a sticker or small toy afterward, the child's memory of the experience is more positive. A nurse never tells a child to be quiet during a painful procedure nor tells them that they are naughty for acting out in pain.

A client, who has undergone a percutaneous transluminal coronary angioplasty (PTCA), has received discharge instructions. Which statement by the client would indicate the need for further teaching by the nurse? "I should avoid taking a tub bath until my catheter site heals." "I should expect a low-grade fever and swelling at the site for the next week." "I should avoid prolonged sitting." "I should expect bruising at the catheter site for up to 3 weeks."

"I should expect a low-grade fever and swelling at the site for the next week." Fever and swelling at the site are signs of infection and should be reported to the physician. Showers should be taken until the insertion site is healed. Prolonged sitting can result in thrombosis formation. Bruising at the insertion site is common and may take from 1 to 3 weeks to resolve.

A client is ordered a nitroglycerine transdermal patch for treatment of CAD and asks the nurse why the patch is removed at bedtime. Which is the best response by the nurse? "Nitroglycerine causes headaches, but removing the patch decreases the incidence." "You do not need the effects of nitroglycerine while you sleep." "Removing the patch at night prevents drug tolerance while keeping the benefits." "Contact dermatitis and skin irritations are common when the patch remains on all day."

"Removing the patch at night prevents drug tolerance while keeping the benefits." Tolerance to antiangina effects of nitrates can occur when taking these drugs for long periods of time. Therefore, to prevent tolerance and maintain benefits, it is a common regime to remove transdermal patches at night. Common adverse effects of nitroglycerin are headaches and contact dermatitis but not the reason for removing the patch at night. It is true that while the client rests, there is less demand on the heart but not the primary reason for removing the patch.

When providing discharge instructions for a client who has been prescribed sublingual nitroglycerin for angina, the nurse should plan to include which instructions? "See if rest relieves the chest pain before using the nitroglycerin." "Call 911 if you develop a headache following nitroglycerin use." "Place the nitroglycerin tablet between cheek and gum." "Only take one nitroglycerin tablet for each episode of angina."

"See if rest relieves the chest pain before using the nitroglycerin." Decreased activity may relieve chest pain; sitting will prevent injury should the nitroglycerin lower BP and cause fainting. The client should expect to feel dizzy or flushed or to develop a headache following sublingual nitroglycerin use. The client should place one nitroglycerin tablet under the tongue if 2-3 minutes of rest fails to relieve pain. Clients may take up to three nitroglycerin tablets within 5 minutes of each other to relieve angina. However, they should call 911 if the three tablets fail to resolve the chest pain.

When assessing a client who reports recent chest pain, the nurse obtains a thorough history. Which client statement most strongly suggests angina pectoris? "The pain lasted about 45 minutes." "The pain resolved after I ate a sandwich." "The pain got worse when I took a deep breath." "The pain occurred while I was mowing the lawn."

"The pain occurred while I was mowing the lawn." Decreased oxygen supply to the myocardium causes angina pectoris. Lawn mowing increases the cardiac workload, which increases the heart's need for oxygen and may precipitate this chest pain. Anginal pain typically is self-limiting, lasting 5 to 15 minutes. Food consumption doesn't reduce angina pain, although it may ease pain caused by a GI ulcer. Deep breathing has no effect on anginal pain.

The nurse is caring for a client experiencing an acute MI (STEMI). The nurse anticipates the physician will prescribe alteplase. Before administering this medication, which question is most important for the nurse to ask the client? "What time did your chest pain start today?" "Do your parents have heart disease?" "How many sublingual nitroglycerin tablets did you take?" "What is your pain level on a scale of 1 to 10?"

"What time did your chest pain start today?" The client may be a candidate for thrombolytic (fibrolytic) therapy. These medications are administered if the client's chest pain lasts longer than 20 minutes and is unrelieved by nitroglycerin, if ST-segment elevation is found in at least two leads that face the same area of the heart, and if it has been less than 6 hours since the onset of pain. The most appropriate question for the nurse to ask is in relations to when the chest pain began. The other questions would not aid in determining whether the client is a candidate for thrombolytic therapy.

A client has just arrived in the ER with a possible myocardial infarction (MI). The electrocardiogram (ECG) should be obtained within which time frame of arrival to the ER? 10 minutes 5 minutes 15 minutes 20 minutes

10 minutes The ECG provides information that assists in diagnosing acute MI. It should be obtained within 10 minutes from the time a client reports pain or arrives in the emergency department. By monitoring serial ECG changes over time, the location, evolution, and resolution of an MI can be identified and monitored.

Following a percutaneous transluminal coronary angioplasty, a client is monitored in the postprocedure unit. The client's heparin infusion was stopped 2 hours earlier. There is no evidence of bleeding or hematoma at the insertion site, and the pressure device is removed. With regards to partial thromboplastin time (PTT), when should the nurse plan to remove the femoral sheath? 50 seconds or less. 75 seconds or less. 100 seconds or less. 125 seconds or less.

50 seconds or less. Heparin causes an elevation of the PTT and, thereby, increases the risk for bleeding. With a large cannulation such as a sheath used for angioplasty, the PTT should be 50 seconds or less before the sheath is removed. Removing the sheath before the PTT drops below 50 seconds can cause bleeding at the insertion site. The other PTT results are incorrect for determining when to remove the sheath.

To be effective, percutaneous transluminal coronary angioplasty (PTCA) must be performed within what time frame, beginning with arrival at the emergency department after diagnosis of myocardial infarction (MI)? 30 minutes 60 minutes 9 days 6 to 12 months

60 minutes The 60-minute interval is known as "door-to-balloon time" in which a PTCA can be performed on a client with a diagnosed MI. The 30-minute interval is known as "door-to-needle time" for the administration of thrombolytics after MI. The time frame of 9 days refers to the time until the onset of vasculitis after administration of streptokinase for thrombolysis in a client with an acute MI. The 6- to 12-month time frame refers to the time period during which streptokinase will not be used again in the same client for acute MI.

60 minutes The 60-minute interval is known as "door-to-balloon time" in which to perform PTCA on a client diagnosed with MI. The 30-minute interval is known as "door-to-needle time" for administration of thrombolytics after MI. The time frame of 9 days refers to the time until the onset of vasculitis after administration of streptokinase for thrombolysis in a client with an acute MI. The 6- to 12-month time frame refers to the time period during which streptokinase will not be used again in the same client for acute MI.

Which medication is an antidote to heparin? Protamine sulfate Alteplase Clopidogrel Aspirin

Protamine sulfate Protamine sulfate is known as the antagonist to heparin. Alteplase is a thrombolytic agent. Clopidogrel is an antiplatelet medication that is given to reduce the risk of thrombus formation post coronary stent placement. The antiplatelet effect of aspirin does not reverse the effects of heparin.

The mother of a 9-year-old girl calls the physician's office complaining that her daughter continues to vomit soon after being given an oral amoxicillin capsule for her strep throat. The nurse recognizes that the child's vomiting will interfere with which pharmacokinetic process? Absorption Distribution Metabolism Excretion

Absorption Drug absorption (transfer of the drug from its point of entry in the body into the bloodstream) is influenced by the route of administration as well as by the concentration and acidity of the drug. Vomiting and diarrhea, frequent symptoms of childhood illnesses, interfere with absorption because a drug does not remain in the gastrointestinal tract long enough to be absorbed. Distribution refers to the movement of the drug through the bloodstream to a specific site of action. Metabolism involves conversion of the drug into an active form (biotransformation) or an inactive form (inactivation). Excretion is the elimination of raw drug or drug metabolites, a process that largely prevents properly administered drugs from becoming toxic.

The charge nurse was discussing with the nursing student that studies have been published that suggest inflammation increases the risk of heart disease. Which modifiable factor would the nursing student target in teaching clients about prevention of inflammation that can lead to atherosclerosis? Avoid use of caffeine Encourage use of a multivitamin Addressing obesity Drink at least 2 liters of water a day

Addressing obesity Published information by Balistreri et al. (2010) indicated a relationship between body fat and the production of inflammatory and thrombotic (clot-facilitating) proteins. This information suggests decreasing obesity and body fat stores may help to reduce the risk. Avoiding the use of caffeine, encouraging the use of a multivitamin, and drinking at least 2 liters of water a day are not actions that will address the prevention of inflammation that can lead to artherosclerosis.

A client in the emergency department reports squeezing substernal pain that radiates to the left shoulder and jaw. The client also complains of nausea, diaphoresis, and shortness of breath. What is the nurse's priority action? Complete the client's registration information, perform an electrocardiogram, gain I.V. access, and take vital signs. Alert the cardiac catheterization team, administer oxygen, attach a cardiac monitor, and notify the health care provider. Gain I.V. access, give sublingual nitroglycerin, and alert the cardiac catheterization team. Administer oxygen, attach a cardiac monitor, take vital signs, and administer sublingual nitroglycerin.

Administer oxygen, attach a cardiac monitor, take vital signs, and administer sublingual nitroglycerin. Cardiac chest pain is caused by myocardial ischemia. Therefore the nurse should administer supplemental oxygen to increase the myocardial oxygen supply, attach a cardiac monitor to help detect life-threatening arrhythmias, and take vital signs to ensure that the client isn't hypotensive before giving sublingual nitroglycerin for chest pain. Registration information may be delayed until the client is stabilized. Alerting the cardiac catheterization team or the health care provider before completing the initial assessment is premature.

Following a percutaneous coronary intervention (PCI), a client is returned to the nursing unit with large peripheral vascular access sheaths in place. The nurse understands that which method to induce hemostasis after sheath is contraindicated? Application of a sandbag to the area Application of a vascular closure device Direct manual pressure Application of a mechanical compression device

Application of a sandbag to the area Applying a sandbag to the sheath insertion site is ineffective in reducing the incidence of bleeding and is not an acceptable standard of care. Application of a vascular closure device (Angio-Seal, VasoSeal), direct manual pressure to the sheath introduction site, and application of a mechanical compression device (a C-shaped clamp) are all appropriate methods used to induce hemostasis after removal of a peripheral sheath.

Which method to induce hemostasis after sheath removal after percutaneous transluminal coronary angioplasty (PTCA) is mosteffective? Application of a vascular closure device such as Angio-Seal or VasoSeal Direct manual pressure Application of a pneumatic compression device (e.g., FemoStop) Application of a sandbag to the area

Application of a vascular closure device such as Angio-Seal or VasoSeal Application of a vascular closure device has been demonstrated to be very effective. Direct manual pressure to the sheath introduction site and application of a pneumatic compression device after PTCA have been demonstrated to be effective; the former was the first method used to induce hemostasis after PTCA. Several nursing interventions frequently used as part of the standard of care, such as applying a sandbag to the sheath insertion site, have not been shown to be effective in reducing the incidence of bleeding.

A client asks the clinic nurse what the difference is between arteriosclerosis and atherosclerosis. What is the nurse's best response? Arteriosclerosis is a loss of elasticity, or hardening of the arteries, that happens as we age. Atherosclerosis is a loss of elasticity, or hardening of the arteries, that happens as we age. Arteriosclerosis is a formation of clots in the inner lining of the arteries. Atherosclerosis is a formation of clots in the inner lining of the arteries.

Arteriosclerosis is a loss of elasticity, or hardening of the arteries, that happens as we age. Arteriosclerosis refers to the loss of elasticity or hardening of the arteries, that accompanies the aging process. Therefore, options B, C, and D are incorrect.

A client reports chest pain and heavy breathing when exercising or when stressed. Which is a priority nursing intervention for the client diagnosed with coronary artery disease? Assess chest pain and administer prescribed drugs and oxygen Assess blood pressure and administer aspirin It is not important to assess the client or to notify the physician Assess the client's physical history

Assess chest pain and administer prescribed drugs and oxygen The nurse assesses the client for chest pain and administers the prescribed drugs that dilate the coronary arteries. The nurse administers oxygen to improve the oxygen supply to the heart. Assessing blood pressure or the client's physical history does not clearly indicate that the client has CAD. The nurse does not administer aspirin without a prescription from the physician.

An older adult is postoperative day one, following a coronary artery bypass graft (CABG). The client's family members express concern to the nurse that the client is uncharacteristically confused. After reporting this change in status to the health care provider, what additional action should the nurse take? Educate the family about how confusion is expected in older adults postoperatively. Assess for factors that may be causing the client's delirium. Document the early signs of dementia and ensure the client's safety. Reorient the client to place and time.

Assess for factors that may be causing the client's delirium. Uncharacteristic changes in cognition following cardiac surgery are suggestive of delirium. Dementia has a gradual onset with organic brain changes and is not an acute response to surgery. Assessment is a higher priority than reorientation, which may or may not be beneficial. Even though delirium is not rare, it is not considered to be an expected part of recovery.

You are caring for a client with CAD. What is an appropriate nursing action when evaluating a client with coronary artery disease (CAD)? Assess the client's mental and emotional status. Assess the skin of the client. Assess the characteristics of chest pain. Assess for any kind of drug abuse.

Assess the characteristics of chest pain. The nurse should assess the characteristics of chest pain for a client with CAD. Assessing the client's mental, emotional status, the skin of the client, or for drug abuse will not assist the nurse in evaluating the client for CAD.

A nurse is caring for a client who is exhibiting signs and symptoms characteristic of a myocardial infarction (MI). Which statement describes priorities the nurse should establish while performing the physical assessment? Assess the client's level of pain and administer prescribed analgesics. Assess the client's level of anxiety and provide emotional support. Prepare the client for pulmonary artery catheterization. Ensure that the client's family is kept informed of the client's status.

Assess the client's level of pain and administer prescribed analgesics. The cardinal symptom of MI is persistent, crushing substernal pain or pressure. The nurse should first assess the client's pain and prepare to administer nitroglycerin or morphine for pain control. The client must be medically stabilized before pulmonary artery catheterization can be used as a diagnostic procedure. Anxiety and a feeling of impending doom are characteristic of MI, but the priority is to stabilize the client medically. Although the client and family members should be kept informed at every step of the recovery process, this action isn't the priority when treating a client with a suspected MI.

A patient has returned to the nursing unit after having a percutaneous coronary intervention (PCI) in the hospital's cardiac catheterization laboratory. The nurse who is providing care for this patient should prioritize what assessment? Assessing the patient's capillary refill time and peripheral pulses Assessing the patient for signs and symptoms of hemorrhage Assessing the patient for signs and symptoms of acute renal failure Assessing the patient for signs and symptoms of infection

Assessing the patient for signs and symptoms of hemorrhage Monitoring the patient for bleeding post-PCI is a priority. Kidney function, peripheral circulation, and infection are also valid assessment parameters but the significant risk of bleeding associated with PCI necessitates that assessments related to this problem be prioritized.

The nurse is presenting a workshop at the senior citizens center about how the changes of aging predispose clients to vascular occlusive disorders. What would the nurse name as the most common cause of peripheral arterial problems in the older adult? Arteriosclerosis Coronary thrombosis Atherosclerosis Raynaud's disease

Atherosclerosis Atherosclerosis is the most common cause of peripheral arterial problems in the older adult. The disease correlates with the aging process. The other choices may occur at any age.

The nurse is caring for a client with Raynaud's disease. What is an important instruction for a client who is diagnosed with this disease to prevent an attack? Report changes in the usual pattern of chest pain. Avoid situations that contribute to ischemic episodes. Avoid fatty foods and exercise. Take over-the-counter decongestants.

Avoid situations that contribute to ischemic episodes. Teaching for clients with Raynaud's disease and their family members is important. They need to understand what contributes to an attack. The nurse should instruct the clients to avoid situations that contribute to ischemic episodes. Reporting changes in the usual pattern of chest pain or avoiding fatty foods and exercise does not help the client to avoid an attack; it is more contributory for clients with CAD. In addition, the nurse advises clients to avoid over-the-counter decongestants.

A client is receiving nitroglycerin ointment to treat angina pectoris. The nurse evaluates the therapeutic effectiveness of this drug by assessing the client's response and checking for adverse effects. Which vital sign is most likely to reflect an adverse effect of nitroglycerin? Pulse rate of 84 beats/minute Respiration 26 breaths/minute Blood pressure 84/52 mm Hg Temperature of 100.2° F (37.9° C)

Blood pressure 84/52 mm Hg Hypotension and headache are the most common adverse effects of nitroglycerin. Therefore, blood pressure is the vital sign most likely to reflect an adverse effect of this drug. The nurse should check the client's blood pressure 1 hour after administering nitroglycerin ointment. A blood pressure decrease of 10 mm Hg is within the therapeutic range. If blood pressure falls more than 20 mm Hg below baseline, the nurse should remove the ointment and report the finding to the physician immediately. An above-normal heart rate (tachycardia) is a less common adverse effect of nitroglycerin. Respiratory rate and temperature don't change significantly after nitroglycerin administration.

Which is a diagnostic marker for inflammation of vascular endothelium? C-reactive protein (CRP) Low-density lipoprotein (LDL) High-density lipoprotein (HDL) Triglyceride

C-reactive protein (CRP) CRP is a marker for inflammation of the vascular endothelium. LDL, HDL, and triglycerides are not markers of vascular endothelial inflammation. They are elements of fat metabolism.

A client with chest pain arrives in the emergency department and receives nitroglycerin, morphine, oxygen, and aspirin. The health care provider diagnoses acute coronary syndrome. When the client arrives on the unit, vital signs are stable and the client does not report any pain. In addition to the medications already given, which medication does the nurse expect the health care provider to order? Carvedilol Digoxin Furosemide Nitroprusside

Carvedilol A client with suspected myocardial infarction should receive aspirin, nitroglycerin, morphine, and a beta-adrenergic blocker such as carvedilol. Digoxin treats arrhythmias; there is no indication that the client is having arrhythmias. Furosemide is used to treat signs of heart failure, which isn't indicated at this point. Nitroprusside increases blood pressure. This client has stable vital signs and isn't hypotensive.

A nurse is caring for a client in the cardiovascular intensive care unit following a coronary artery bypass graft. Which clinical finding requires immediate intervention by the nurse? Central venous pressure reading of 1 Pain score 5/10 Blood pressure 110/68 mm Hg Heart rate 66 bpm

Central venous pressure reading of 1 The central venous pressure (CVP) reading of 1 is low (2-6 mm Hg) and indicates reduced right ventricular preload, commonly caused by hypovolemia. Hypovolemia is the most common cause of decreased cardiac output after cardiac surgery. Replacement fluids such as colloids, packed red blood cells, or crystalloid solutions may be prescribed. The other findings require follow-up by the nurse; however, addressing the CVP reading is the nurse's priority.

A middle-aged client presents to the ED reporting severe chest discomfort. Which finding is most indicative of a possible myocardial infarction (MI)? Chest discomfort not relieved by rest or nitroglycerin Intermittent nausea and emesis for 3 days Cool, clammy skin and a diaphoretic, pale appearance Anxiousness, restlessness, and lightheadedness

Chest discomfort not relieved by rest or nitroglycerin Chest pain or discomfort not relieved by rest or nitroglycerin is associated with an acute MI. The other findings, although associated with acute coronary syndrome or MI, may also occur with angina and, alone, are not indicative of an MI.

A client comes to the Emergency Department (ED) complaining of precordial chest pain. In describing the pain, the client describes it as pressure with a sudden onset. What disease process would you suspect in this client? Coronary artery disease Raynaud's disease Cardiogenic shock Venous occlusive disease

Coronary artery disease The classic symptom of CAD is chest pain (angina) or discomfort during activity or stress. Such pain or discomfort typically is manifested as sudden pain or pressure that may be centered over the heart (precordial) or under the sternum (substernal). Raynaud's disease in the hands presents with symptoms of hands that are cold, blanched, and wet with perspiration. Cardiogenic shock is a complication of an MI. Venous occlusive disease occurs in the veins, not the arteries.

Coronary artery disease The classic symptom of CAD is chest pain (angina) or discomfort during activity or stress. Such pain or discomfort typically is manifested as sudden pain or pressure that may be centered over the heart (precordial) or under the sternum (substernal). Raynaud's disease in the hands presents with symptoms of hands that are cold, blanched, and wet with perspiration. Cardiogenic shock is a complication of an MI. Venous occlusive disease occurs in the veins, not the arteries.

A nurse is caring for a client who experienced an MI. The client is ordered to received metoprolol. The nurse understands that this medication has which therapeutic effect? Decreases resting heart rate Decreases cholesterol level Increases cardiac output Decreases platelet aggregation

Decreases resting heart rate The therapeutic effects of beta-adrenergic blocking agents such as metoprolol are to reduce myocardial oxygen consumption by blocking beta-adrenergic sympathetic stimulation to the heart. The result is reduced heart rate, slowed conduction of impulses through the conduction system, decreased blood pressure, and reduced myocardial contractility to balance the myocardial oxygen needs and amount of oxygen available. This helps to control chest pain and delays the onset of ischemia during work or exercise. This classification of medication also reduces the incidence of recurrent angina, infarction, and cardiac mortality. In general, the dosage of medication is titrated to achieve a resting heart rate of 50-60 bpm. Metoprolol is not administered to decrease cholesterol levels, increase cardiac output, or decrease platelet aggregation.

The public health nurse is participating in a health fair, and she interviews a woman with a history of hypertension who is currently smoking one pack of cigarettes per day. She has had no manifestations of coronary artery disease (CAD) but a recent low-density lipoprotein (LDL) level of 154 mg/dL was found. Based on her assessment, the nurse would expect that this patient would be treated in what way? Drug therapy and smoking cessation Diet and drug therapy Diet therapy only Diet therapy and smoking cessation

Diet therapy and smoking cessation Diet therapy is indicated for a patient without CAD who has two or more risk factors (hypertension and cigarette smoking) and an LDL level equal to or greater than 130 mg/dL. When the patient's LDL levels are equal to or greater than 160 mg/dL, drug therapy would be added to diet therapy. Cigarette smoking contributes to the development and severity of CAD and is listed as a major risk factor.

You are caring for a client who is suspected of having coronary artery disease. The client is scheduled to have a nuclear stress test using thallium. When would the thallium be injected to determine narrowing of the coronary arteries? During and a few hours after exercise electrocardiography. Before and during exercise electrocardiography. Before and a few hours after exercise electrocardiography. Before, during, and a few hours after exercise electrocardiography.

During and a few hours after exercise electrocardiography. A nuclear stress test using a radionuclide, such as thallium, may be injected intravenously (IV) during and a few hours after exercise electrocardiography, followed by a heart scan. Narrowing of one or more coronary arteries is documented during coronary arteriography. Therefore, options B, C, and D are incorrect.

A client comes to the emergency department reporting chest pain. An electrocardiogram (ECG) reveals myocardial ischemia and an anterior-wall myocardial infarction (MI). Which ECG characteristic does the nurse expect to see? Prolonged PR interval Absent Q wave Elevated ST segment Widened QRS complex

Elevated ST segment Ischemic myocardial tissue changes cause elevation of the ST segment, an inverted T wave, and a pathological Q wave. A prolonged PR interval occurs with first-degree heart block, the least dangerous atrioventricular heart block; this disorder may arise in healthy people but sometimes results from drug toxicity, electrolyte or metabolic disturbances, rheumatic fever, or chronic degenerative disease of the conduction system. An absent Q wave is normal; an MI may cause a significant Q wave. A widened QRS complex indicates a conduction delay in the His-Purkinje system.

The nurse is discussing risk factors for developing CAD with a patient in the clinic. Which results would indicate that the patient is not at significant risk for the development of CAD? Cholesterol, 280 mg/dL Low density lipoprotein (LDL), 160 mg/dL High-density lipoprotein (HDL), 80 mg/dL A ratio of LDL to HDL, 4.5 to 1.0

High-density lipoprotein (HDL), 80 mg/dL A fasting lipid profile should demonstrate the following values (Alberti et al., 2009): LDL cholesterol less than 100 mg/dL (less than 70 mg/dL for very high-risk patients); total cholesterol less than 200 mg/dL; HDL cholesterol greater than 40 mg/dL for males and greater than 50 mg/dL for females; and triglycerides less than 150 mg/dL.

A nurse is caring for a client after cardiac surgery. Upon assessment, the client appears restless and reports nausea and weakness. The client's ECG reveals peaked T waves. The nurse reviews the client's serum electrolytes, anticipating which abnormality? Hyperkalemia Hypercalcemia Hypomagnesemia Hyponatremia

Hyperkalemia Hyperkalemia is indicated by mental confusion, restlessness, nausea, weakness, and dysrhythmias (tall, peaked T waves). Hypercalcemia would likely be demonstrated by asystole. Hypomagnesemia would likely be demonstrated by hypotension, lethargy, and vasodilation. Hyponatremia would likely be indicated by weakness, fatigue, and confusion, without changes in T-wave formation.

Which of the following is inconsistent as a condition related to metabolic syndrome? Hypotension Insulin resistance Abdominal obesity Dyslipidemia

Hypotension A diagnosis of metabolic syndrome includes three of the following conditions: insulin resistance, abdominal obesity, dyslipidemia, hypertension, proinflammatory state, and prothrombotic state.

A new surgical patient who has undergone a coronary artery bypass graft (CABG) is receiving opioids for pain control. The nurse must be alert to adverse effects of opioids. Which of the following effects would be important for the nurse to document? Hypotension Urinary incontinence Hyperactive bowel sounds Hypertension

Hypotension The patient is observed for any adverse effects of opioids, which may include respiratory depression, hypotension, ileus, or urinary retention. If serious side effects occur, an opioid antagonist, such as Narcan, may be used.

A client admitted to the coronary care unit (CCU) diagnosed with a STEMI is anxious and fearful. Which medication will the nurse administer to relieve the client's anxiety and decrease cardiac workload? IV morphine IV nitroglycerin Atenolol Amlodipine

IV morphine IV morphine is the analgesic of choice for the treatment of an acute MI. It is given to reduce pain and treat anxiety. It also reduces preload and afterload, which decreases the workload of the heart. IV nitroglycerin is given to alleviate chest pain. Administration of atenolol and amlodipine are not indicated in this situation.

When the nurse notes that, after cardiac surgery, the client demonstrates low urine output (less than 25 mL/h) with high specific gravity (greater than 1.025), the nurse suspects which condition? Inadequate fluid volume Normal glomerular filtration Overhydration Anuria

Inadequate fluid volume Urine output less than 0.5 mL/kg/h may indicate a decrease in cardiac output. A high specific gravity indicates increased concentration of solutes in the urine, which occurs with inadequate fluid volume. Indices of normal glomerular filtration are output of 0.5 mL/kg/h or more and specific gravity between 1.010 and 1.025. Overhydration is manifested by high urine output with low specific gravity. The anuric client does not produce urine.

The nurse is educating a patient diagnosed with angina pectoris about the difference between the pain of angina and a myocardial infarction (MI). How should the nurse describe the pain experienced during an MI? (Select all that apply.) It is relieved by rest and inactivity. It is substernal in location. It is sudden in onset and prolonged in duration. It is viselike and radiates to the shoulders and arms. It subsides after taking nitroglycerin.

It is substernal in location. It is sudden in onset and prolonged in duration. It is viselike and radiates to the shoulders and arms. Chest pain that occurs suddenly, continues despite rest and medication, is substernal, and is sometimes viselike and radiating to the shoulders and arms is associated with an MI. Angina pectoris pain is generally relieved by rest and nitroglycerin.

An electrocardiogram (ECG) taken during a routine checkup reveals that a client has had a silent myocardial infarction. Changes in which leads of a 12-lead ECG indicate damage to the left ventricular septal region? Leads I, aVL, V5, and V6 Leads II, III, and aVF Leads V1 and V2 Leads V3 and V4

Leads V3 and V4 Leads V3 and V4 record electrical events in the septal region of the left ventricle. Leads I, aVL, V5, and V6 record electrical events on the lateral surface of the left ventricle. Leads II, III, and aVF record electrical events on the inferior surface of the left ventricle. Leads V1 and V2 record electrical events on the anterior surface of the right ventricle and the anterior surface of the left ventricle.

A nurse is teaching a client who receives nitrates for the relief of chest pain. Which instruction should the nurse emphasize? Repeat the dose of sublingual nitroglycerin every 15 minutes for three doses. Store the drug in a cool, well-lit place. Lie down or sit in a chair for 5 to 10 minutes after taking the drug. Restrict alcohol intake to two drinks per day.

Lie down or sit in a chair for 5 to 10 minutes after taking the drug. Nitrates act primarily to relax coronary smooth muscle and produce vasodilation. They can cause hypotension, which makes the client dizzy and weak. The nurse should instruct the client to lie down or sit in a chair for 5 to 10 minutes after taking the drug. Nitrates are taken at the first sign of chest pain and before activities that might induce chest pain. Sublingual nitroglycerin is taken every 5 minutes for three doses. If the pain persists, the client should seek medical assistance immediately. Nitrates must be stored in a dark place in a closed container because sunlight causes the medication to lose its effectiveness. Alcohol is prohibited because nitrates may enhance the effects of the alcohol.

A child is reporting pain where an IV infiltrated his hand earlier in the shift. The doctor orders warm compresses to the right hand every 4 hours. What precautions would the nurse implement for this client? Heat the moistened towels in the microwave to heat them up each time. Use hot water on gauze for the warm compress. Limit treatments to 20 minutes at a time. Have the parents apply the warm compresses if the nurse is tied up elsewhere.

Limit treatments to 20 minutes at a time. Warm compresses are used to increase circulation to an area of the body and to promote pain relief. For a child having warm compresses, the length of each session is a maximum of 20 minutes to prevent skin damage. Towels used in warm compresses are never heated in a microwave because of uneven heating. Parents are not to apply compresses because the nurse needs to assess the skin before and after the treatment. Gauze is not a good material for compresses; it does not hold heat well.

The triage nurse in the emergency department assesses a 66-year-old male patient who has presented to the emergency department with complaints of midsternal chest pain that has lasted for the last 5 hours. The care team suspects a myocardial infarction (MI). The nurse is aware that, because of the length of time the patient has been experiencing symptoms, the following may have happened to the myocardium: May have developed an increased area of infarction Will probably not have more damage than if he came in immediately Can have restoration of the area of dead cells with proper treatment Has been damaged already, so immediate treatment is no longer necessary

May have developed an increased area of infarction When the patient experiences lack of oxygen to myocardium cells during an MI, the sooner treatment is initiated the more likely the treatment will prevent or minimize myocardial tissue necrosis. Despite the length of time the symptoms have been present, treatment needs to be initiated immediately to minimize further damage.

Which technique is used to surgically revascularize the myocardium? Balloon bypass Peripheral bypass Minimally invasive direct coronary bypass Gastric bypass

Minimally invasive direct coronary bypass Several techniques are used to surgically revascularize the myocardium; one of them is minimally invasive direct coronary bypass. Balloon bypass is not used to revascularize the myocardium. If the client is experiencing acute pain in the leg, peripheral bypass is performed. Gastric bypass is a surgical procedure that alters the process of digestion.

Which is the analgesic of choice for acute myocardial infarction (MI)? Morphine Aspirin Meperidine Ibuprofen

Morphine The analgesic of choice for acute MI is morphine administered in IV boluses to reduce pain and anxiety. Aspirin is an antiplatelet medication. Meperidine and Ibuprofen are not the analgesics of choice.

Severe chest pain is reported by a client during an acute myocardial infarction. Which of the following is the most appropriate drug for the nurse to administer? Isosorbide mononitrate (Isordil) Meperidine hydrochloride (Demerol) Morphine sulfate (Morphine) Nitroglycerin transdermal patch

Morphine sulfate (Morphine) Morphine sulfate not only decreases pain perception and anxiety but also helps to decrease heart rate, blood pressure, and demand for oxygen. Nitrates are administered for vasodilation and pain control in clients with angina-type pain, but oral forms (such as isosorbide dinitrate) have a large first-pass effect, and transdermal patch is used for long-term management. Meperidine hydrochloride is a synthetic opioid usually reserved for treatment of postoperative or migraine pain.

A 45-year-old adult male patient is admitted to emergency after he developed unrelieved chest pain that was present for approximately 20 minutes before he presented to the emergency department. The patient has been subsequently diagnosed with a myocardial infarction (MI). To minimize cardiac damage, what health care provider's order will the nurse expect to see for this patient? Thrombolytics, oxygen administration, and bed rest Morphine sulfate, oxygen administration, and bed rest Oxygen administration, anticoagulants, and bed rest Bed rest, albuterol nebulizer treatments, and oxygen administration

Morphine sulfate, oxygen administration, and bed rest Morphine sulfate reduces preload and decreases workload of the heart, along with increased oxygen from oxygen therapy and bed rest. With decreased cardiac demand, this provides the best chance of decreasing cardiac damage. Thrombolytics and anticoagulants are contraindicated in patients who are bleeding or have a bleeding disorder. Albuterol is a medication used to manage asthma and respiratory conditions and will increase the heart rate.

A nurse reviews a client's medication history before administering a cholinergic blocking agent. Adverse effects of a cholinergic blocking agent may delay absorption of what medication? Amantadine Nitroglycerin Digoxin Diphenhydramine

Nitroglycerin A cholinergic blocking agent may cause dry mouth and delay the sublingual absorption of nitroglycerin. The nurse should offer the client sips of water before administering nitroglycerin. Amantadine, digoxin, and diphenhydramine can interact with a cholinergic blocking agent but not through delayed absorption. Amantadine and diphenhydramine enhance the effects of anticholinergic agents.

A client presents to the ED reporting anxiety and chest pain after shoveling heavy snow that morning. The client says that nitroglycerin has not been taken for months but upon experieincing this chest pain did take three nitroglycerin tablets. Although the pain has lessened, the client states, "They did not work all that well." The client shows the nurse the nitroglycerin bottle; the prescription was filled 12 months ago. The nurse anticipates which order by the physician? Nitroglycerin SL Chest x-ray Serum electrolytes Ativan 1 mg orally

Nitroglycerin SL Nitroglycerin is volatile and is inactivated by heat, moisture, air, light, and time. Nitroglycerin should be renewed every 6 months to ensure full potency. The client's tablets were expired, and the nurse should anticipate administering nitroglycerin to assess whether the chest pain subsides. The other choices may be ordered at a later time, but the priority is to relieve the client's chest pain.

While receiving a heparin infusion to treat deep vein thrombosis, a client reports bleeding in the gums when brushing teeth. What should the nurse do first? Stop the heparin infusion immediately. Notify the health care provider. Administer a coumarin derivative, as ordered, to counteract heparin. Reassure the client that bleeding gums are a normal effect of heparin.

Notify the health care provider. Because heparin can cause bleeding gums that may indicate excessive anticoagulation, the nurse should notify the health care provider, who will evaluate the client's condition. The health care provider should order laboratory tests such as partial thromboplastin time before concluding that the client's bleeding is significant. The ordered heparin dose may be therapeutic rather than excessive, so the nurse shouldn't discontinue the heparin infusion unless the health care provider orders this after evaluating the client. Protamine sulfate, not a coumarin derivative, is given to counteract heparin. Heparin doesn't normally cause bleeding gums.

The nurse is caring for a client following a coronary artery bypass graft (CABG). The nurse notes persistent oozing of bloody drainage from various puncture sites. The nurse anticipates that the physician will order which medication to neutralize the unfractionated heparin the client received? Protamine sulfate Alteplase Clopidogrel Aspirin

Protamine sulfate Protamine sulfate is known as the antagonist for unfractionated heparin (it neutralizes heparin). Alteplase is a thrombolytic agent. Clopidogrel is an antiplatelet medication that is given to reduce the risk of thrombus formation after coronary stent placement. The antiplatelet effect of aspirin does not reverse the effects of heparin.

Following cardiac surgery, the nurse assesses the client for any common complication of hypovolemia. What significant indication of a complication should the nurse monitor? Heart rate of 60 bpm Central venous pressure (CVP) reading of 8 mm Hg Pulmonary artery wedge pressure (PAWP) of 6 mm Hg Blood pressure reading of 130/95 mm Hg

Pulmonary artery wedge pressure (PAWP) of 6 mm Hg In the presence of hypovolemia, the circulating blood volume would be significantly decreased. Therefore, the PAWP would be lower than 8 to 10 mm Hg. The normal CVP reading (2 to 8 mm Hg) would be decreased. The heart rate would be increased and the blood pressure decreased.

After undergoing cardiac surgery, a client discovers a painless lump and reports this to the nurse. What is the most important nursing intervention for this client? Reassure the client by informing him or her that the lump will disappear with time. Inform the client that the lump will be removed by the surgeon. Reassure the client by informing him or her that the lump will disappear after a course of drug therapy. Reassure the client and direct the client to the health care provider.

Reassure the client by informing him or her that the lump will disappear with time. The nurse will reassure the client by informing him or her that the lump will disappear with time and will not require surgery, drug therapy, or a visit to the health care provider.

A triage team is assessing a client to determine if reported chest pain is a manifestation of angina pectoris or an MI. The nurse knows that a primary distinction of angina pain is? Described as crushing and substernal Associated with nausea and vomiting Relieved by rest and nitroglycerin Accompanied by diaphoresis and dyspnea

Relieved by rest and nitroglycerin One characteristic that can differentiate the pain of angina from a myocardial infarction is pain that is relieved by rest and nitroglycerine. There may be some exceptions (unstable angina), but the distinction is helpful especially when combined with other assessment data.

The nurse is caring for a client presenting to the emergency department (ED) reporting chest pain. Which electrocardiographic (ECG) finding would be most concerning to the nurse? ST elevation Isolated premature ventricular contractions (PVCs) Sinus tachycardia Frequent premature atrial contractions (PACs)

ST elevation The first signs of an acute MI are usually seen in the T wave and the ST segment. The T wave becomes inverted; the ST segment elevates (it is usually flat). An elevated ST segment in two contiguous leads is a key diagnostic indicator for MI (i.e., ST-elevation MI). This client requires immediate invasive therapy or fibrinolytic medications. Although the other ECG findings require intervention, elevated ST elevations require immediate and definitive interventions.

In arteriosclerosis, commonly referred to as hardening of the arteries, the rigid arterial vessels fail to stretch. This has the potential for what? Decreasing the flow of unoxygenated blood through the body Slowing the flow of blood throughout the body Increasing the flow of blood throughout the body Sending a reduced volume of oxygenated blood to the major organs of the body

Sending a reduced volume of oxygenated blood to the major organs of the body As the left ventricle contracts, sending oxygenated blood from the heart, the rigid arterial vessels fail to stretch. The potential result is a reduced volume of oxygenated blood delivered to organs such as the myocardium, brain, kidneys, and extremities. Arteriosclerosis does not decrease the flow of unoxygenated blood throughout the body; it does not slow or increase the flow of blood throughout the body.

The nurse is caring for a client with abdominal aortic aneurysm (AAA). Which assessment finding is most likely to indicate a dissection of the aneurysm? Severe back pain Hematemesis Rectal bleeding Hypertensive crisis

Severe back pain Pressure from an enlarging or dissecting abdominal aortic aneurysm is likely to be exhibited as severe back pain. A decrease in blood pressure will result as the client goes into shock from hemorrhaging. Blood in emesis or rectal bleeding is not associated with rupture of AAA.

A preschooler who is receiving gastrostomy feedings occasionally vomits following a feeding. When the parent describes the feeding process, what does the nurse note as the likely cause of the vomiting? The mother does not check gastric residual prior to feedings. Caretakers omit flushing the tube at the conclusion of bolus feedings. Bolus feedings are administered over a period of about 25 minutes. A feeding pump is used to administer the feedings.

The mother does not check gastric residual prior to feedings. Because gastric residual (amount left in the stomach from prior feeding) is not checked before feeding, there may be times the child's stomach is overfilled when the current nutritional material is added. Aspirating to measure residual would confirm this as well as provide data about how fast the child's stomach is emptying. The feeding plan may need to be modified. Not flushing the tube would not be related to vomiting. Using 25 minutes to administer a bolus feeding is an appropriate amount of time in most instances. A feeding pump would precisely control feeding rate and should not be the source of vomiting.

The nurse has brought a 3-year-old's oral medications into the room for administration. Upon approaching the child, the nurse said, "I have your medication. Would you rather have me hand it to you or Mommy?" In critiquing the nurse's actions, which is most accurate? The nurse's behavior is correct. Children are afraid of the nurse. The nurse's behavior is correct. The nurse provided the child a choice between two acceptable options with the outcome of taking the medication. The nurse's behavior is incorrect. The nurse should have been firm in expecting the child to take the medication. The nurse's behavior is incorrect. The mother did not prepare the medication and should not have administered the medication.

The nurse's behavior is correct. The nurse provided the child a choice between two acceptable options with the outcome of taking the medication. The nurse is correct to offer a choice to the preschooler and then for the mother to administer the medication, if chosen. This meets the developmental level of autonomy. The nurse prepared the medication and the medication remained with the nurse until handing it to the mother, who handed it to the child. The nurse witnessed the medication administration and documents it. The nurse firmly requires the medication to be taken but found a way for the child to take it that was acceptable to the child and accomplished the goal.

A patient with angina is beginning nitroglycerin. Before administering the drug, the nurse informs the patient that, immediately after administration, the patient may experience what? Nervousness or paresthesia Throbbing headache or dizziness Drowsiness or blurred vision Tinnitus or diplopia

Throbbing headache or dizziness Headache and dizziness commonly occur when nitroglycerin is taken at the beginning of therapy. However, the patient usually develops a tolerance. Nervousness, paresthesia, drowsiness, blurred vision, tinnitus, and diplopia don't occur as a result of nitroglycerin therapy.

In the treatment of coronary artery disease (CAD), medications are often ordered to control blood pressure in the client. Which of the following is a primary purpose of using beta-adrenergic blockers in the nursing management of CAD? To dilate coronary arteries To decrease workload of the heart To decrease homocysteine levels To prevent angiotensin II conversion

To decrease workload of the heart Beta-adrenergic blockers are used in the treatment of CAD to decrease the myocardial oxygen by reducing heart rate and workload of the heart. Nitrates are used for vasodilation. Anti-lipid drugs (such as statins and Bvitamins) are used to decrease homocysteine levels. ACE inhibitors inhibit the conversion of angiotensin.

The client has had biomarkers tested after reporting chest pain. Which diagnostic marker of myocardial infarction remains elevated for as long as 2 weeks? Myoglobin Troponin Total creatine kinase CK-MB

Troponin Troponin remains elevated for a long period, often as long as 2 weeks, and it therefore can be used to detect recent myocardial damage. Myoglobin peaks within 12 hours after the onset of symptoms. Total creatine kinase (CK) returns to normal in 3 days. CK-MB returns to normal in 3 to 4 days.

When a client who has been diagnosed with angina pectoris reports experiencing chest pain more frequently, even at rest, that the period of pain is longer, and that it takes less stress for the pain to occur, the nurse recognizes that the client is describing which type of angina? Intractable Variant Unstable Refractory

Unstable Unstable angina is also called crescendo or preinfarction angina and indicates the need for a change in treatment. Intractable or refractory angina produces severe, incapacitating chest pain that does not respond to conventional treatment. Variant angina is described as pain at rest with reversible ST-segment elevation and is thought to be caused by coronary artery vasospasm. Intractable or refractory angina produces severe, incapacitating chest pain that does not respond to conventional treatment.

Which term refers to preinfarction angina? Stable angina Unstable angina Variant angina Silent ischemia

Unstable angina Preinfarction angina is also known as unstable angina. Stable angina has predictable and consistent pain that occurs upon exertion and is relieved by rest. Variant angina is exhibited by pain at rest and reversible ST-segment elevation. Silent angina manifests through evidence of ischemia, but the client reports no symptoms.

The nurse is reevaluating a client 2 hours after a percutaneous transluminal coronary angioplasty (PTCA) procedure. Which assessment finding may indicate the client is experiencing a complication of the procedure? Urine output of 40 mL Potassium level of 4.0 mE/qL Heart rate of 100 bpm Dried blood at the puncture site

Urine output of 40 mL Complications that may occur following a PTCA include myocardial ischemia, bleeding and hematoma formation, retroperitoneal hematoma, arterial occlusion, pseudoaneurysm formation, arteriovenous fistula formation, and acute renal failure. The urine output of 40 mL over a 2-hour period may indicate acute renal failure. The client is expected to have a minimum urine output of 30 mL/h. Dried blood at the insertion site is a finding that warrants no acute intervention. A serum potassium level of 4.0 mEq/L is within the normal range. The heart rate of 100 bpm is within the normal range and indicates no acute distress.

The nurse knows that women and the elderly are at greater risk for a fatal myocardial event. Which factor is the primary contributor of this cause? Chest pain is typical Vague symptoms Decreased sensation to pain Gender bias

Vague symptoms Often, women and elderly do not have the typical chest pain associated with a myocardial infarction. Some report vague symptoms (fatigue, abdominal pain), which can lead to misdiagnosis. Some older adults may experience little or no chest pain. Gender is not a contributing factor for fatal occurrence but rather a result of symptoms association.

The nurse is preparing to administer an IV antibiotic to a child. After calculating the recommended dose with the child's weight, the nurse discovers the prescribed dose exceeds the safe dose range in a pediatric drug book. The medication has been given to the child at this dose for 3 days. What action should the nurse take next? Verify the dose with the prescribing health care provider. Give the prescribed dose since the child has been receiving that dose for 3 days. Ask the child's parents if this dose has been given all week. Call the pharmacy.

Verify the dose with the prescribing health care provider. Medication calculations should always be checked before giving the dose. When a medication dose is found to be outside of the safe dose range, the dose should be verified with the prescribing health care provider. Doses that exceed the recommended range should always be verified, even if they have been given before. The parents did not prescribe this medication. Even if the medication has been given for 3 days, it does not make the dose correct. Calling the pharmacy can only verify if the dose is out of the safe range. The pharmacy did not prescribe the medication nor does it know the child's medical background.

The nurse is preparing to administer a medication via a syringe pump as ordered for a 2-month-old girl. Which is the prioritynursing action? Gather the medication Verify the medication order Gather the necessary equipment and supplies Wash hands and put on gloves

Verify the medication order The priority nursing action is to verify the medication ordered. The first step in the eight rights of pediatric medication administration is to ensure that the child is receiving the right medication. After verifying the order, the nurse would then gather the medication, the necessary equipment and supplies, wash hands and put on gloves.

At what point does a child convert to the adult dosing for medication administration? When the child reaches a weight of 110 lb (50 kg) When the child reaches a weight of 100 lb (45 kg) When the child reaches the age of 12 years When the child reaches the age of 16 years

When the child reaches a weight of 110 lb (50 kg) Adult dose reference ranges, rather than kilogram dosing, may be used in children who weigh more than 110 lb (50 kg). Weight in kilograms is the standard used for medication administration in pediatrics.The pediatric dose should not exceed the recommended adult dose. Age is not the factor for recommending adult dosing; it is weight measured in killograms rather than pounds.

A client is admitted to the emergency department with chest pain and doesn't respond to nitroglycerin. The health care team obtains an electrocardiogram and administers I.V. morphine. The health care provider also considers administering alteplase. This thrombolytic agent must be administered how soon after onset of myocardial infarction (MI) symptoms? Within 6 hours Within 12 hours Within 24 to 48 hours Within 5 to 7 days

Within 6 hours For the best chance of salvaging the client's myocardium, a thrombolytic agent must be administered within 6 hours after onset of chest pain or other signs or symptoms of MI. Sudden death is most likely to occur within the first 24 hours after an MI. Health care providers initiate I.V. heparin therapy after administration of a thrombolytic agent; it usually continues for 5 to 7 days.

Which client with a venous stasis ulcer is a candidate for topical hyperbaric oxygen therapy? a client with a chronic, nonhealing skin lesion a client whose ulcer includes necrotic tissue a client with an infected stasis ulcer a nonambulatory client

a client with a chronic, nonhealing skin lesion Chronic, nonhealing skin lesions are treated with topical hyperbaric oxygen therapy. This approach delivers oxygen above atmospheric pressure directly to the wound rather than to the full body as with other disorders such as carbon monoxide poisoning. Necrotic tissue is debrided from a stasis ulcer. A client's infection is treated with an application of Silvadene, an antibacterial cream, or an antibiotic ointment and an occlusive transparent dressing such as Tegaderm that traps moisture and speeds healing.

A client presents to the ED with a myocardial infarction. Prior to administering a prescribed thrombolytic agent, the nurse must determine whether the client has which absolute contraindication to thrombolytic therapy? prior intracranial hemorrhage recent consumption of a meal shellfish allergy use of heparin

prior intracranial hemorrhage History of a prior intracranial hemorrhage is an absolute contraindication for thrombolytic therapy. An allergy to iodine, shellfish, radiographic dye, and latex are of primary concern before a cardiac catheterization but not a known contraindication for thrombolytic therapy. Administration of a thrombolytic agent with heparin increases risk of bleeding; the primary healthcare provider usually discontinues the heparin until thrombolytic treatment is completed.
