Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Administering oxygen is the priority intervention for a patient with a suspected pulmonary embolism to improve oxygenation levels. In pulmonary embolism, there is a blockage in one of the pulmonary arteries, leading to decreased oxygen exchange. Administering oxygen helps increase oxygen saturation levels. Anticoagulants (Choice B) are essential in the treatment of pulmonary embolism but are not the initial priority intervention. Surgery (Choice C) is not typically the first-line treatment for pulmonary embolism. Monitoring oxygen saturation (Choice D) is important but administering oxygen takes precedence as the immediate action to address hypoxemia.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance necessitates close monitoring to prevent complications such as cardiac arrhythmias. Choices B, C, and D are incorrect. Hypercalcemia is not a common side effect of furosemide. Hyponatremia is more commonly associated with other medications like thiazide diuretics. Hyperkalemia is the opposite electrolyte imbalance and is not typically seen with furosemide use.

Correct Answer: A

Rationale: The correct answer is to monitor serum creatinine. In patients with chronic kidney disease, monitoring serum creatinine is crucial as it reflects kidney function. This assessment helps healthcare providers in evaluating the progression of the disease and adjusting treatment plans accordingly. Monitoring blood pressure (choice B) is essential in managing chronic kidney disease, but monitoring serum creatinine takes precedence. Monitoring urine output (choice C) and potassium levels (choice D) are also important aspects of managing chronic kidney disease, but they are not the priority assessment compared to monitoring serum creatinine.

Correct Answer: A

Rationale: When educating a client about nutritional intake, it is important to mention that carbohydrates should constitute at least 45% of their daily caloric intake for a balanced diet. This macronutrient provides energy and is essential for proper bodily functions. Choice B is incorrect because protein should typically account for around 10-35% of total caloric intake, not 55%. Choice C is too low for the recommended carbohydrate intake, as it should be higher at 45%. Choice D is incorrect as protein intake should generally be around 10-35% of total caloric intake, not 60%.

Correct Answer: D

Rationale: Stridor is a high-pitched sound that indicates airway obstruction and is the priority finding to report following a thyroidectomy. In this situation, airway compromise is a critical concern that requires immediate intervention to ensure adequate oxygenation. While calcium level (Choice A) and serum sodium level (Choice B) are important assessments post-thyroidectomy, they do not represent an immediate threat to the client's airway. A respiratory rate of 18/min (Choice C) falls within the normal range and does not indicate an immediate risk to the client's airway compared to the presence of stridor.
