How is secondary hypertension differentiated from primary hypertension?
- A. Has a more gradual onset than primary hypertension
- B. Does not cause the target organ damage that occurs with primary hypertension
- C. Has a specific cause, such as renal disease, that often can be treated by medicine or surgery
- D. Is caused by age-related changes in BP regulatory mechanisms in people over 65 years of age
Correct Answer: C
Rationale: Secondary hypertension arises from identifiable causes.

Which condition refers to the heart being unable to pump sufficient blood to meet the body's needs?
- A. Heart failure
- B. Myocardial infarction
- C. Cardiomyopathy
- D. Pericarditis
Correct Answer: A
Rationale: The correct answer is A: Heart failure. This condition occurs when the heart is unable to pump enough blood to meet the body's needs. It can result from various factors such as high blood pressure, heart muscle damage, or heart valve disorders. In contrast, B (Myocardial infarction) refers to a heart attack caused by a blockage in the coronary arteries, C (Cardiomyopathy) is a disease of the heart muscle, and D (Pericarditis) is inflammation of the pericardium surrounding the heart. These conditions may affect the heart's function but do not specifically indicate the inability to pump sufficient blood like heart failure does.
What condition involves a weakened and bulging aorta, the main artery in the body, potentially leading to rupture?
- A. Aortic aneurysm
- B. Arterial stenosis
- C. Pulmonary embolism
- D. Deep vein thrombosis
Correct Answer: A
Rationale: The correct answer is A: Aortic aneurysm. A weakened and bulging aorta is a characteristic of an aortic aneurysm, which can lead to a rupture if left untreated. Aneurysms can develop due to various factors such as high blood pressure, atherosclerosis, and genetic predisposition. The other choices, B (Arterial stenosis), C (Pulmonary embolism), and D (Deep vein thrombosis) are not correct because they do not specifically involve a weakened and bulging aorta. Arterial stenosis refers to narrowing of an artery, pulmonary embolism is a blockage in a lung artery, and deep vein thrombosis is a blood clot in a deep vein. Only aortic aneurysm fits the description provided in the question.
What is the abnormal accumulation of fluid in the pleural space, often associated with infections or malignancies?
- A. Pleural effusion
- B. Pneumothorax
- C. Pulmonary edema
- D. Atelectasis
Correct Answer: A
Rationale: The correct answer is A: Pleural effusion. Pleural effusion is the abnormal accumulation of fluid in the pleural space, commonly caused by infections or malignancies. This condition leads to symptoms like chest pain and difficulty breathing. Pneumothorax (B) is the presence of air in the pleural space, not fluid. Pulmonary edema (C) is the accumulation of fluid in the lungs' air sacs, not the pleural space. Atelectasis (D) is the collapse of a lung or part of a lung, not fluid accumulation in the pleural space.
Which of the following is a chronic condition where the heart muscle is weakened and unable to pump blood effectively, often leading to heart failure?
- A. Dilated cardiomyopathy
- B. Hypertrophic cardiomyopathy
- C. Restrictive cardiomyopathy
- D. Myocarditis
Correct Answer: A
Rationale: Rationale:
1. Dilated cardiomyopathy (A) is characterized by the heart muscle becoming weak and enlarged, leading to ineffective pumping.
2. Hypertrophic cardiomyopathy (B) involves thickened heart muscle but not necessarily weakened.
3. Restrictive cardiomyopathy (C) involves stiffening of the heart muscle, not necessarily weakening.
4. Myocarditis (D) is inflammation of the heart muscle, not specifically related to chronic weakening and heart failure.
Therefore, A is the correct answer as it directly relates to the weakened heart muscle leading to ineffective pumping and heart failure.
Which order should the nurse question?
- A. The addition of a loop diuretic with digoxin.
- B. The addition of a beta blocker with digoxin.
- C. A digoxin dose of 0.125 mg per day.
- D. The addition of an ACE inhibitor with digoxin.
Correct Answer: B
Rationale: The correct answer is B: The addition of a beta blocker with digoxin. When combined, beta blockers can enhance the effects of digoxin, leading to an increased risk of bradycardia and heart block. This combination can also exacerbate digoxin toxicity. Therefore, the nurse should question the addition of a beta blocker with digoxin to prevent potential adverse effects.
Incorrect choices:
A: The addition of a loop diuretic with digoxin - Loop diuretics may lead to hypokalemia, which can increase the risk of digoxin toxicity.
C: A digoxin dose of 0.125 mg per day - This is within the recommended dose range for digoxin and does not pose a significant concern.
D: The addition of an ACE inhibitor with digoxin - ACE inhibitors are commonly used in combination with digoxin and do not typically interact negatively.
