Correct Answer: B

Rationale: The correct answer is B because prednisone is usually prescribed for long-term use. Stopping it abruptly can lead to adrenal insufficiency. Choice A is incorrect because prednisone should be taken with food to prevent stomach upset. Choice C is incorrect as prednisone is typically tapered off gradually to avoid adverse effects. Choice D is incorrect as there is no specific requirement to take prednisone with a high-protein snack.

Correct Answer: B

Rationale: The correct answer is B. A glucose level of 250 mg/dL indicates hyperglycemia, which is expected in DKA. However, in the context of DKA management, persistent or worsening hyperglycemia can indicate inadequate treatment response or complications, necessitating further monitoring and intervention. Potassium levels are crucial in DKA due to the risk of hypokalemia, but a level of 4.2 mEq/L is within the normal range. Bicarbonate levels are typically low in DKA, making a value of 20 mEq/L consistent with the condition. Sodium levels of 135 mEq/L are also within normal limits and not a priority for immediate reporting in the context of DKA.

Correct Answer: D

Rationale: The correct answer is D because clients taking spironolactone should have their potassium levels checked regularly. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and can lead to hyperkalemia if levels become too high. Choices A, B, and C are incorrect because avoiding foods high in potassium, sodium, or monitoring blood pressure are not specific to the teaching related to spironolactone.

Correct Answer: B

Rationale: The correct answer is B. Assisting a client with ambulation post-surgery is a task that can be appropriately delegated to assistive personnel (AP) as it falls within their scope of duties. Teaching a new mother how to breastfeed and helping with medication administration involve assessments and critical thinking that are typically within the scope of licensed nursing staff, not AP. Delegating IV medication administration involves a higher level of skill and knowledge that should be performed by licensed nursing staff.

Correct Answer: D

Rationale: Verifying the pH of the gastric aspirate is the correct action to take before administering an intermittent enteral feeding through an NG tube. This step ensures proper tube placement in the stomach, as the gastric aspirate should have an acidic pH (usually below 5). Heating the feeding solution, elevating the head of the bed, or flushing the tube with saline are not directly related to verifying tube placement and are not the immediate actions needed before administering the feeding.
