Chap 33 - PQ2

c (The patient's symptoms are consistent with the development of pericarditis, a possible complication of MI. The other assessments listed are not consistent with the description of the patient's symptoms.)

A patient recovering from a myocardial infarction (MI) develops chest pain on day 3 that increases when taking a deep breath and is relieved by leaning forward. Which action should the nurse take as focused follow-up on this symptom? a. Assess both feet for pedal edema. b. Palpate the radial pulses bilaterally. c. Auscultate for a pericardial friction rub. d. Check the heart monitor for dysrhythmias.

b (A change in heart rate of more than 20 beats over the resting heart rate indicates that the patient should stop and rest. The increases in BP and respiratory rate, and the slight decrease in O2 saturation, are normal responses to exercise.)

A patient who has recently had an acute myocardial infarction (AMI) ambulates in the hospital hallway. Which data would indicate to the nurse that the patient should stop and rest? a. O2 saturation drops from 99% to 95%. b. Heart rate increases from 66 to 98 beats/min. c. Respiratory rate goes from 14 to 20 breaths/min. d. Blood pressure (BP) changes from 118/60 to 126/68 mm Hg.

b (Sexual activity places about as much physical stress on the cardiovascular system as moderate-energy activities, such as climbing two flights of stairs. The other responses are general statements that may be accurate, but do not provide useful guidelines for judging the physical safety of the activity.)

A patient who is recovering from an acute myocardial infarction (AMI) asks the nurse about safely resuming sexual intercourse. Which response by the nurse is best? a. "Most patients are able to enjoy intercourse without any complications." a. "Sexual activity uses about as much energy as climbing two flights of stairs." c. "The doctor will provide sexual guidelines when your heart is strong enough." d. "Holding and cuddling are good ways to maintain intimacy after a heart attack."

c (Thrombolytic therapy should be started within 6 hours of the onset of the myocardial infarction, so the time at which the chest pain started is a major determinant of the appropriateness of this treatment. The other information is not a factor in the decision about thrombolytic therapy.)

A patient with ST-segment elevation in three contiguous electrocardiographic leads is admitted to the emergency department and diagnosed as having an ST-segment-elevation myocardial infarction (STEMI). Which question should the nurse ask to determine whether the patient is a candidate for thrombolytic therapy? a. "Do you have any allergies?" b. "Do you take aspirin daily?" c. "What time did your pain begin?" d. "Can you rate the pain on a 0 to 10 scale?"

c (The purpose for angiotensin-converting enzyme (ACE) inhibitors in patients with chronic stable angina who are at high risk for a cardiac event is to decrease ventricular remodeling. ACE inhibitors do not directly impact angina frequency, blood glucose, or heart rate.)

A patient with diabetes mellitus and chronic stable angina has a new order for captopril. What should the nurse teach this patient about the primary purpose of captopril? a. Decreases the heart rate. b. Controls blood glucose levels. c. Prevents changes in heart muscle. d. Reduces the frequency of chest pain.

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

Heparin is ordered for a patient with a non-ST-segment-elevation myocardial infarction (NSTEMI). How should the nurse explain the purpose of the heparin to the patient? a. "Heparin enhances platelet aggregation at the plaque site." b. "Heparin decreases the size of the coronary artery plaque." c. "Heparin prevents the development of new clots in the coronary arteries." d. "Heparin dissolves clots that are blocking blood flow in the coronary arteries."

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

In preparation for discharge, the nurse teaches a patient with chronic stable angina how to use the prescribed short-acting and long-acting nitrates. Which patient statement indicates that the teaching has been effective? a. "I will sit down before I put the nitroglycerin under my tongue." b. "I will check my pulse rate before I take any nitroglycerin tablets." c. "I will put the nitroglycerin patch on as soon as I get any chest pain." d. "I will remove the nitroglycerin patch before taking sublingual nitroglycerin."

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

The nurse is administering a thrombolytic agent to a patient with an acute myocardial infarction. What patient data indicates that the nurse should stop the drug infusion? a. Bleeding from the gums b. An increase in blood pressure c. Decreased level of consciousness d. A nonsustained episode of ventricular tachycardia

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

The nurse is caring for a patient who is recovering from a sudden cardiac death (SCD) event and has no evidence of an acute myocardial infarction (AMI). What should the nurse anticipate teaching the patient? a. Sudden cardiac death events rarely reoccur. b. Additional diagnostic testing will be required. c. Long-term anticoagulation therapy will be needed. d. Limiting physical activity will prevent future SCD events.

b (When the internal mammary artery is used, there is no need to have a saphenous vein removed from the leg. The other statements by the patient are accurate and indicate that the teaching has been effective.)

The nurse is evaluating the effectiveness of preoperative teaching with a patient scheduled for coronary artery bypass graft (CABG) surgery using the internal mammary artery. Which patient statement indicates that additional teaching is needed? a. "They will circulate my blood with a machine during surgery." b. "I will have incisions in my leg where they will remove the vein." c. "They will use an artery near my heart to go around the area that is blocked." d. "I will need to take aspirin every day after the surgery to keep the graft open."

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

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