Correct Answer: B

Rationale: Redness and warmth in the calf can indicate a blood clot, specifically deep vein thrombosis (DVT), which is a serious complication post hip arthroplasty. The warmth and redness are signs of inflammation due to the clot formation. DVT can lead to a pulmonary embolism if not addressed promptly. Monitoring for this complication is crucial in postoperative care. Elevated heart rate, oxygen saturation within normal limits, and a slightly elevated temperature are common findings postoperatively and may not be alarming in the absence of other concerning symptoms.

Correct Answer: A

Rationale: Providing education on medication is crucial when managing a patient with non-compliance to hypertension medication. By educating the patient on the importance of adherence, potential side effects, and the impact of uncontrolled hypertension, healthcare professionals can help improve the patient's understanding and compliance.

Choice
B) may be necessary in some cases but should not be the first step. Discontinuing the medication (

Choice D, '
To treat allergic reactions,' is incorrect as antiemetics are not primarily used for treating allergic reactions.

Correct Answer: C

Rationale: The correct answer is C: 'Notify your provider if you experience visual disturbances.' Visual disturbances can indicate digoxin toxicity, so it is essential for clients taking digoxin to report any changes in vision to their healthcare provider. Option A is incorrect because the timing of digoxin administration is crucial, usually in the morning. Option B is inaccurate because digoxin should not be taken with milk as it can affect its absorption. Option D is not directly associated with digoxin use and should not be the priority instruction for a client on this medication.

Correct Answer: A

Rationale: The correct answer is A: 'The client's urine output decreases.' Desmopressin is used to treat diabetes insipidus by reducing excessive urine output.
