1. What is a genetic disorder that affects the lungs and digestive system, leading to thick, sticky mucus that can clog the airways?

Correct answer: A

Rationale: The correct answer is A, cystic fibrosis. Cystic fibrosis is a genetic disorder that primarily affects the lungs and digestive system. It leads to the production of thick, sticky mucus that can clog the airways, causing respiratory issues. Choice B, COPD (Chronic Obstructive Pulmonary Disease), is a different condition usually caused by smoking or exposure to irritants. Choice C, bronchiectasis, involves the widening and scarring of the airways, not the production of thick mucus. Choice D, pulmonary fibrosis, is a lung disease characterized by scarring of the lung tissue, not excessive mucus production.

2. The client on furosemide (Lasix) has a potassium level of 3.1 mEq/L. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is to administer a potassium supplement. A potassium level of 3.1 mEq/L indicates hypokalemia, which can lead to serious complications like cardiac dysrhythmias. Therefore, the priority action is to address the low potassium level by administering a potassium supplement. Holding the furosemide (Choice B) may be necessary in the long term to prevent further potassium loss, but the immediate need is to correct the low potassium level. Continuing the current dose of furosemide (Choice C) without addressing the low potassium level can worsen hypokalemia. Administering Digibind (Choice D) is not indicated for low potassium levels; Digibind is used to treat digoxin toxicity.

3. A client on spironolactone (Aldactone) has a potassium level of 6.0 mEq/L. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct action for a client on spironolactone with a potassium level of 6.0 mEq/L is to hold the medication and notify the healthcare provider. Spironolactone is a potassium-sparing diuretic that can further elevate potassium levels, which are already high. Administering a potassium supplement (Choice B) would exacerbate the hyperkalemia. Continuing the spironolactone as ordered (Choice C) could lead to worsening hyperkalemia. Increasing the dose of spironolactone (Choice D) would be contraindicated in the presence of elevated potassium levels.

4. 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.

5. The client is receiving digoxin and complains of nausea. What is the nurse’s priority action?

Correct answer: A

Rationale: The correct answer is to check the client’s digoxin level (Choice A). Nausea can be a sign of digoxin toxicity, so assessing the digoxin level is crucial to determine if the medication dosage needs adjustment. Continuing the current dose of digoxin (Choice B) may worsen the symptoms if toxicity is present. Administering an antiemetic (Choice C) may provide temporary relief but does not address the underlying issue of digoxin toxicity. Discontinuing digoxin immediately (Choice D) without assessing the digoxin level can be harmful if the medication is within the therapeutic range.
