Correct Answer: B

Rationale: Oliguria is a sign of decreased cardiac output. Decreased cardiac output can lead to poor renal perfusion, resulting in decreased urine output (oliguria). This requires immediate intervention to improve cardiac function and perfusion. Shivering (Choice A) is a response to cold stress and does not directly indicate decreased cardiac output. Bradypnea (Choice C) refers to abnormally slow breathing rate and is more indicative of respiratory issues rather than decreased cardiac output. Constricted pupils (Choice D) are associated with the parasympathetic nervous system response and not directly related to cardiac output.

Correct Answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

Correct Answer: B

Rationale: To prevent aspiration in clients with a nasogastric tube receiving intermittent enteral feedings, the nurse should elevate the head of the bed to 45 degrees during feedings. This position helps reduce the risk of regurgitation and aspiration of the feeding contents. Administering a bolus feeding over 10 minutes (choice A) may not prevent aspiration as effectively as elevating the head of the bed. Flushing the tube with sterile water before feedings (choice C) is important for tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (choice D) is not the recommended action to prevent aspiration; elevating the head of the bed is more effective.

Correct Answer: B

Rationale: The correct answer is Hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion by increasing its excretion in the urine. Hypokalemia is a common and concerning side effect of furosemide therapy. Hyperkalemia (Choice A) is less likely as furosemide tends to lower potassium levels. Hyponatremia (Choice C) is more commonly seen with thiazide diuretics. Hypercalcemia (Choice D) is not directly associated with furosemide use.

Correct Answer: D

Rationale: The correct answer is D: 'I have the right to refuse treatment.' This statement shows an understanding of advance directives because they allow individuals to specify their treatment preferences in advance, including the right to refuse treatment. Choices A, B, and C are incorrect. Choice A is inaccurate as individuals can update or change their advance directives at any time. Choice B is incorrect because while a doctor may discuss advance directives with the client, approval is not required for the directives to be valid. Choice C is also incorrect as a witness is typically required to verify the client's signature, not the other way around.
