Correct Answer: A

Rationale: The correct answer is A. Roast beef is high in heme iron, which is best absorbed and helps treat iron deficiency anemia. Choices B, C, and D do not contain significant sources of iron, especially heme iron, making them less effective in treating iron deficiency anemia.

Correct Answer: B

Rationale: An apical rate of 140 bpm is within the normal range for a newborn. Digoxin is commonly used to treat heart failure by increasing the strength and efficiency of the heart's contractions. Since the heart rate is within the normal range, there is no need to hold the medication or notify the healthcare provider. Rechecking the apical rate in an hour is unnecessary as the heart rate is not alarming. Therefore, the appropriate nursing action is to administer the digoxin.

Correct Answer: C

Rationale: The correct intervention for a client with an ileal conduit is to report to the healthcare provider any decrease in urinary output. A decrease in urinary output can be indicative of a blockage or other complication, necessitating immediate attention. Choice A is incorrect because pouching the stoma with a margin around it is not directly related to managing complications. Choice B is incorrect as referring the client to an ostomy association may be beneficial for education but is not the immediate action needed for decreased urinary output. Choice D is incorrect because monitoring for infection, although important, is not the priority when dealing with a potential complication like decreased urinary output.

Correct Answer: A

Rationale: Choice A is the best method of applying adult teaching principles because repeating information and addressing the client's questions as they arise is effective for reinforcing learning in adults. This approach allows for clarification of doubts and ensures that the client understands the information provided. Choice B is incorrect as teaching all the information in one session may overwhelm the client and hinder retention. Choice C is incorrect as using medical terms without ensuring the client's understanding may lead to confusion. Choice D is incorrect because waiting for the client to ask questions may result in missed opportunities to address important information proactively.

Correct Answer: A

Rationale: Mild tenderness, a light diet initially, and gas or bloating are expected after a colonoscopy.
