1. The client on spironolactone (Aldactone) has a potassium level of 5.6 mEq/L. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is A: Hold the spironolactone and notify the healthcare provider. A potassium level of 5.6 mEq/L is high, indicating hyperkalemia. Spironolactone is a potassium-sparing diuretic that can further elevate potassium levels. Therefore, the priority action is to withhold the medication to prevent exacerbating hyperkalemia and notify the healthcare provider for further management. Option B is incorrect because administering potassium supplements would worsen the hyperkalemia. Option C is incorrect as continuing spironolactone can lead to a further increase in potassium levels. Option D is incorrect as increasing the dose of spironolactone would be inappropriate in the presence of elevated potassium levels.

2. What is a condition where a blood clot forms in a deep vein, usually in the legs, and can lead to serious complications if it travels to the lungs?

Correct answer: A

Rationale: The correct answer is A, Deep vein thrombosis (DVT). Deep vein thrombosis occurs when a blood clot forms in a deep vein, usually in the legs. If the clot dislodges and travels to the lungs, it can lead to a serious condition called a pulmonary embolism. Choice B, pulmonary embolism, is incorrect as it is the consequence of a DVT clot traveling to the lungs, not the initial condition. Choices C and D, varicose veins, and Raynaud's disease, respectively, are unrelated conditions to the formation of blood clots in deep veins.

3. What is the term for the ability of cardiac cells to respond to a stimulus by initiating a cardiac impulse?

Correct answer: A

Rationale: The correct answer is A, Excitability. Excitability is the ability of cardiac cells to respond to a stimulus by initiating a cardiac impulse. Choice B, Contractility, refers to the ability of cardiac muscle to shorten forcibly. Choice C, Rhythmicity, refers to the cardiac muscle's ability to contract rhythmically. Choice D, Conductivity, refers to the ability of the heart's cells to conduct electrical impulses.

4. The client on furosemide (Lasix) is complaining of muscle cramps. What electrolyte imbalance should the nurse suspect?

Correct answer: D

Rationale: The correct answer is D, Hypokalemia. Muscle cramps are a common symptom of hypokalemia, an electrolyte imbalance characterized by low potassium levels. Furosemide, a loop diuretic like Lasix, can lead to potassium loss in the body, contributing to hypokalemia. Choice A, Hyperkalemia, is incorrect as it refers to high potassium levels. Choice B, Hyponatremia, is incorrect as it pertains to low sodium levels. Choice C, Hypocalcemia, is incorrect as it relates to low calcium levels, not typically associated with muscle cramps in the context of furosemide use.

5. What is a condition where the heart's mitral valve does not close properly, causing blood to leak backward into the left atrium?

Correct answer: A

Rationale: Mitral valve prolapse is the correct answer. It occurs when the mitral valve does not close properly, leading to blood leaking backward into the left atrium. This condition can manifest with symptoms such as palpitations and chest pain. Choices B, C, and D are incorrect because aortic stenosis involves narrowing of the aortic valve, mitral stenosis is the narrowing of the mitral valve, and tricuspid regurgitation is when blood leaks backward through the tricuspid valve.
