The client on nitroglycerin complains of a headache. What is the most appropriate response by the nurse?
- A. Administer acetaminophen as prescribed for the headache.
- B. Hold the next dose of nitroglycerin.
- C. Discontinue the nitroglycerin immediately.
- D. Notify the healthcare provider immediately.
Correct Answer: A
Rationale: The correct response is to administer acetaminophen as prescribed for the headache. This is because headaches are a common side effect of nitroglycerin due to vasodilation. Acetaminophen can help relieve the headache without interfering with the therapeutic effects of nitroglycerin. Holding the next dose (B) is not appropriate as it can lead to inadequate treatment of the client's condition. Discontinuing nitroglycerin (C) abruptly can be dangerous as it may cause rebound hypertension. Notifying the healthcare provider (D) is not necessary unless the headache persists or worsens.

What is the patient with primary hypertension likely to report?
- A. No symptoms
- B. Cardiac palpitations
- C. Dyspnea on exertion
- D. Dizziness and vertigo
Correct Answer: A
Rationale: Primary hypertension often lacks overt symptoms.
Which heart chamber receives oxygenated blood from the lungs and pumps it to the rest of the body?
- A. Left atrium
- B. Right atrium
- C. Left ventricle
- D. Right ventricle
Correct Answer: C
Rationale: The correct answer is C, the left ventricle. The left ventricle receives oxygenated blood from the lungs through the left atrium and pumps it to the rest of the body via the aorta. This chamber has thicker muscular walls compared to the right ventricle to generate enough force to propel blood throughout the body. The left atrium receives oxygenated blood from the lungs but does not pump blood out to the body. The right atrium receives deoxygenated blood from the body and sends it to the right ventricle, which then pumps it to the lungs for oxygenation. Therefore, choices A, B, and D are incorrect as they do not accurately describe the function of the heart chamber that receives oxygenated blood from the lungs and pumps it to the rest of the body.
Which of the following adverse effects should a nurse check for when administering lidocaine?
- A. Convulsions
- B. Amnesia
- C. Dyspnea
- D. Urinary retention
Correct Answer: A
Rationale: Convulsions are a serious adverse effect of lidocaine toxicity, requiring vigilant monitoring.
What type of heart disease is characterized by the heart muscle becoming enlarged and weakened, reducing its ability to pump blood effectively?
- A. Dilated cardiomyopathy
- B. Hypertrophic cardiomyopathy
- C. Restrictive cardiomyopathy
- D. Myocarditis
Correct Answer: A
Rationale: The correct answer is A: Dilated cardiomyopathy. This condition is characterized by the heart muscle becoming enlarged and weakened, leading to reduced pumping efficiency. This results in symptoms like fatigue, shortness of breath, and swelling. In contrast, hypertrophic cardiomyopathy (B) is characterized by thickening of the heart muscle, restrictive cardiomyopathy (C) involves stiffness of the heart muscle, and myocarditis (D) is inflammation of the heart muscle. These conditions do not specifically involve the enlargement and weakening seen in dilated cardiomyopathy.
What is a condition where the heart's electrical impulses are blocked or delayed, leading to a slower or irregular heartbeat?
- A. Heart block
- B. Atrial fibrillation
- C. Tachycardia
- D. Bradycardia
Correct Answer: A
Rationale: The correct answer is A: Heart block. Heart block refers to a condition where the heart's electrical impulses are blocked or delayed, leading to a slower or irregular heartbeat. This occurs when there is interference with the electrical signals that control the heart's rhythm as they travel through the heart's conduction system. Atrial fibrillation (B) is an irregular and often rapid heart rate that can occur due to chaotic electrical signals in the heart's upper chambers. Tachycardia (C) is a condition where the heart rate is too fast, not slower or irregular. Bradycardia (D) refers to a slow heart rate but not necessarily due to electrical impulse blockage.
