Correct Answer: B

Rationale: Hyperpigmentation and hypotension are classic clinical manifestations of Addison's disease due to decreased cortisol production. Hyperpigmentation occurs due to elevated levels of ACTH, leading to increased melanin synthesis. Hypotension results from aldosterone deficiency, causing sodium loss and volume depletion.

Correct Answer: A

Rationale: In a client with dysphagia, hypoactive bowel sounds, and a firm, distended abdomen post-CVA, continuous tube feeding at 65 ml/hr via gastrostomy may exacerbate abdominal distension and hypoactive bowel sounds. This situation requires immediate assessment and reevaluation before continuing with the prescription.

Correct Answer: B

Rationale: An elevated serum potassium level of 6.2 mEq/L in a client with AKI can lead to life-threatening cardiac arrhythmias, necessitating immediate intervention. Hyperkalemia is a serious complication in AKI as impaired kidney function can result in the accumulation of potassium in the blood, posing a risk of cardiac arrest. Prompt treatment to lower potassium levels is crucial to prevent cardiac complications in this situation.

Correct Answer: B

Rationale: A low Braden score indicates a high risk for pressure ulcers, making regular turning crucial to prevent skin breakdown.

Correct Answer: B

Rationale: In the scenario described, with the client's apical pulse being 58 beats/minute, holding the medication and notifying the healthcare provider is the correct action. A low pulse rate may indicate bradycardia and may necessitate dose adjustment or further evaluation by the healthcare provider to prevent potential complications.
