Mannitol

Answer and Explanation

The Correct Answer is B

Choice A reason: Hydrochlorothiazide is a thiazide diuretic that typically causes potassium loss, not hyperkalemia.

Choice B reason: Spironolactone is a potassium-sparing diuretic, which can lead to an increase in potassium levels, potentially causing hyperkalemia.

Correct Answer is A

Explanation

Choice A reason: Elevating the patient in a high Fowler's position can help improve lung expansion and oxygenation, and using an incentive spirometer along with coughing can help prevent atelectasis and pneumonia, which are common postoperative complications.

Choice B reason: Increasing oxygen to 70% without a specific indication could lead to oxygen toxicity, especially without assessing the patient's current oxygenation status.

Choice C reason: Switching to a rebreather mask is not indicated based on the given ABG results and could lead to CO2 retention.

Choice D reason: Positioning the patient prone and performing postural drainage are not typically first-line interventions for a patient one day post-thoracotomy and could be contraindicated due to the recent surgery.

A. Hyperactive bowel sounds B. Decreased deep tendon reﬂexes C. Cerebral edema D. Weakening

Correct Answer is B

Explanation

Choice A reason: Hyperactive bowel sounds are not typically associated with hyperkalemia, which is a high level of potassium in the blood.

Choice B reason: Decreased deep tendon reﬂexes can be a sign of hyperkalemia, as high potassium levels can aﬀect neuromuscular function.

Choice C reason: Cerebral edema is not a direct manifestation of hyperkalemia; it is more commonly associated with other conditions such as traumatic brain injury or stroke.

Choice D reason: Weakening, or muscle weakness, can be a symptom of hyperkalemia, but it is less specific than decreased deep tendon reﬂexes.
