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.

Correct Answer: C

Rationale: Dependent edema is a common finding in clients with pneumonia due to fluid retention and decreased mobility. Bradycardia (Choice A) is not typically associated with pneumonia. Crackles in the lung bases (Choice B) are more commonly heard in conditions like heart failure or pulmonary edema. A productive cough (Choice D) can be seen in pneumonia but is not as specific as dependent edema.

Correct Answer: C

Rationale: The correct answer is C. Sleeping on the affected side could increase the risk of dislocation following a hip arthroplasty. It is essential for the client to avoid sleeping on the surgical side to prevent complications. Choices A, B, and D are correct statements that promote proper postoperative care and reduce the risk of complications. Avoiding crossing legs when sitting, using a raised toilet seat for proper positioning, and performing leg exercises regularly help in the recovery process and prevent complications.

Correct Answer: A

Rationale: The most important nursing assessment for a patient with suspected deep vein thrombosis (DVT) is to check for leg pain. Leg pain is a cardinal symptom of DVT and is often the initial indicator of a blood clot. While assessing for warmth, swelling, and redness are also important in DVT evaluation, leg pain is the most crucial as it can prompt further diagnostic testing and interventions. Performing Homan's sign test is no longer recommended due to its low specificity and potential to dislodge a clot, causing complications. Monitoring for redness is important but may not always be present in DVT cases. Assessing for warmth and swelling is relevant but still secondary to the assessment of leg pain in suspected DVT cases.

Correct Answer: A

Rationale: The correct answer is A, Bradycardia. Bradycardia, or a slower than normal heart rate, is a classic sign of digoxin toxicity. Digoxin is a medication commonly used to treat heart conditions, but an excess of digoxin in the body can lead to toxicity. This toxicity can manifest as various symptoms, with bradycardia being one of the most common ones. Hypertension (high blood pressure) and tachycardia (fast heart rate) are not typical signs of digoxin toxicity. Tachypnea, which refers to rapid breathing, is also not a common sign of digoxin toxicity.
