Correct Answer: C

Rationale: The correct answer is C: Tingling of the extremities. Tingling is a common symptom of hypocalcemia, which is expected with low calcium levels after a thyroidectomy. Option A, shortened QT intervals, is associated with hypercalcemia rather than hypocalcemia. Option B, hypoactive deep tendon reflexes, is not typically related to hypocalcemia. Option D, constipation, is not a common finding associated with low calcium levels.

Correct Answer: C

Rationale: The correct answer is to instruct the client to 'Move slowly when standing up.' Codeine can cause orthostatic hypotension, a drop in blood pressure when changing positions, leading to dizziness or fainting. By advising the client to move slowly when standing up, the nurse helps prevent falls or injuries due to sudden drops in blood pressure. Choices A, B, and D are important instructions as well but not the priority when considering the risk of orthostatic hypotension associated with codeine.

Correct Answer: A

Rationale: The correct way to evaluate the effectiveness of a diuretic in a patient with heart failure is by checking daily weights and lung sounds for improvement. Daily weights help to assess fluid retention changes, while improvement in lung sounds indicates reduced pulmonary congestion. Assessing blood pressure and urine output (Choice B) is important but does not directly evaluate the effectiveness of the diuretic. Monitoring for weight loss and reduction in edema (Choice C) are valid indicators of diuretic effectiveness, but direct observation of daily weights and lung sounds is more specific. Measuring heart rate and lung sounds (Choice D) is relevant but does not directly assess the impact of the diuretic on fluid balance and pulmonary status.

Correct Answer: D

Rationale: Performing a bladder scan is the first step to assess bladder retention before any further interventions.

Correct Answer: B

Rationale: The correct answer is B: Decreased anginal pain. Verapamil is a calcium channel blocker used to relieve angina by reducing myocardial oxygen demand. Monitoring for decreased anginal pain is essential as it indicates a therapeutic response to the medication. Choices A, C, and D are incorrect as verapamil's primary goal in this context is not to decrease blood pressure, heart rate, or anxiety.
