A patient with angina is prescribed nitroglycerin sublingual tablets. The nurse should instruct the patient to take another dose if chest pain is not relieved in: A) 5 minutes B) 10 minutes C) 15 minutes D) 30 minutes

Answer:A) 5 minutes Rationale:Nitroglycerin can be taken every 5 minutes, up to three doses. If the pain persists after the third dose, the patient should seek emergency medical care as this could indicate a heart attack.

A patient is started on lisinopril. What side effect should the nurse monitor for? A) Dry cough B) Bradycardia C) Hyperglycemia D) Constipation

Answer:A) Dry cough Rationale:Lisinopril, an ACE inhibitor, commonly causes a persistent dry cough due to increased bradykinin levels. If the cough becomes bothersome, another antihypertensive class may be prescribed.

The nurse is teaching a patient about metoprolol. Which statement by the patient indicates a need for further teaching? A) "I will monitor my heart rate regularly." B) "I can stop taking the drug if my blood pressure is normal." C) "I will take the medication at the same time every day." D) "I may feel tired at first, but this will improve."

Answer:B) "I can stop taking the drug if my blood pressure is normal." Rationale:Beta-blockers like metoprolol should not be stopped abruptly, as this can cause rebound hypertension or angina. The patient should continue taking the medication as prescribed, even if blood pressure normalizes.

A patient with chest pain is prescribed nitroglycerin. Which instruction should the nurse provide? A) "Take the medication with food." B) "Lie down before taking the medication." C) "Chew the tablet for faster absorption." D) "Avoid drinking water with the medication."

Answer:B) "Lie down before taking the medication." Rationale:Nitroglycerin causes vasodilation, which can result in dizziness or hypotension. The patient should lie down to prevent fainting or falls due to sudden blood pressure drops.

A patient on furosemide for heart failure asks why they are losing weight. What is the nurse's best response? A) "You're losing fat from the medication." B) "The medication helps your body get rid of excess fluid." C) "Your muscle mass decreases with this medication." D) "Your appetite is reduced due to the drug."

Answer:B) "The medication helps your body get rid of excess fluid." Rationale:Furosemide is a diuretic used in heart failure to remove excess fluid. Weight loss in this context is due to a reduction in fluid volume, not fat or muscle loss.

A patient taking atorvastatin reports muscle pain and weakness. What should the nurse do next? A) Suggest stretching exercises B) Assess for signs of rhabdomyolysis C) Encourage more fluid intake D) Reassure the patient this is a common side effect

Answer:B) Assess for signs of rhabdomyolysis Rationale:Statins like atorvastatin can cause rhabdomyolysis, a serious condition characterized by muscle pain, weakness, and potential kidney damage. The nurse should assess further and contact the healthcare provider.

The nurse is caring for a patient receiving digoxin for heart failure. Which of the following findings indicates digoxin toxicity? A) Increased appetite B) Blurred or yellow vision C) Increased heart rate D) Weight gain

Answer:B) Blurred or yellow vision Rationale:Digoxin toxicity often presents with visual disturbances such as blurred vision, yellow or green halos, nausea, vomiting, and bradycardia. Monitoring digoxin levels and electrolytes, especially potassium, is crucial.

A patient is prescribed an adrenergic agonist. Which of the following effects would the nurse expect to see? A) Decreased heart rate B) Increased bronchodilation C) Increased digestive activity D) Constricted pupils

Answer:B) Increased bronchodilation Rationale:Adrenergic agonists stimulate the sympathetic nervous system (fight or flight response), leading to increased bronchodilation to improve oxygenation. They also increase heart rate and decrease digestive activity.

A patient is receiving dopamine to treat shock. What is the primary action of dopamine in this situation? A) Decrease heart rate B) Increase urine output C) Increase blood pressure D) Decrease respiratory rate

Answer:C) Increase blood pressure Rationale:Dopamine is an adrenergic agonist that increases cardiac output by enhancing contractility and vasoconstriction, which raises blood pressure, especially in shock situations.

The nurse is administering amiodarone to a patient with an arrhythmia. Which assessment finding would require immediate intervention? A) Blood pressure of 110/70 mmHg B) Respiratory rate of 14 breaths/min C) Patient reports difficulty breathing D) Heart rate of 82 beats per minute
