Cardiovascular System Exam

1. The client on spironolactone should avoid which of the following?

Correct answer: A

Rationale: The correct answer is A: Foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and excrete sodium. Consuming foods high in potassium while on spironolactone can lead to an excess of potassium in the body, potentially causing hyperkalemia. Choices B, C, and D are incorrect because spironolactone does not directly interact with sodium, calcium, or chloride in a way that would require specific dietary restrictions related to these minerals.

2. What is the condition where the lung collapses due to air leaking into the space between the lung and chest wall?

Correct answer: A

Rationale: Pneumothorax is the correct answer. It is the collapse of a lung due to air leaking into the space between the lung and chest wall. This condition often requires emergency treatment. Choice B, Pleural effusion, is the buildup of excess fluid between the layers of the pleura outside the lung, not air. Choice C, Pulmonary fibrosis, is a lung disease characterized by scarring and thickening of lung tissue, not related to lung collapse. Choice D, Lung cancer, is the uncontrolled growth of abnormal cells in the lung, not directly causing lung collapse.

3. What is a condition where the blood pressure in the arteries is consistently too high, increasing the risk of heart disease and stroke?

Correct answer: A

Rationale: Hypertension, also known as high blood pressure, is a condition where the force of the blood against the artery walls is consistently too high. This increased pressure can lead to serious health issues such as heart disease and stroke. Hypotension (choice B) refers to low blood pressure, which is not the correct term in this context. Diabetes (choice C) and hyperlipidemia (choice D) are also serious conditions but are not specifically characterized by consistently high blood pressure.

4. Which of the following is a central vasodilator and peripheral vasoconstrictor?

Correct answer: A

Rationale: The correct answer is the Sympathetic nervous system. The sympathetic nervous system is a branch of the autonomic nervous system that is responsible for the fight-or-flight response. It causes vasodilation in central vessels to increase blood flow to vital organs during stress or exercise, while inducing vasoconstriction in peripheral vessels to redirect blood to essential areas. Norepinephrine and acetylcholine are neurotransmitters associated with the sympathetic and parasympathetic nervous systems, respectively, but they are not themselves central vasodilators and peripheral vasoconstrictors.

5. The nurse is administering digoxin to a client with a heart rate of 45 bpm. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A heart rate of 45 bpm is already low, and digoxin can further decrease the heart rate, leading to serious complications like bradycardia or heart block. Administering the medication can exacerbate the bradycardia, hence it should be withheld. Increasing the dose of digoxin is contraindicated due to the client's low heart rate. Monitoring the heart rate alone without taking immediate action to withhold the medication is not the priority when faced with the risk of further lowering the heart rate.
