A nurse in a provider's office is reinforcing teaching about disease prevention with an older adult client. Which of the following immunizations should the nurse recommend to the client?

knee-chest. During sigmoidoscopy, the client should lie on their left side with their right knee flexed slightly. The nurse should then position the client in the knee-chest (Sims) position, where the client leans forward with bent knees and support the chest and forearms on the table or a pillow. This allows better visualization and access to the rectal area for the sigmoidoscopy procedure.

An explanation for incorrect choices:

A. Orthopneic position is upright sitting with arms and elbows resting on a table or on a pillow, which helps clients who have difficulty breathing; it is not suitable for sigmoidoscopy.

B. Trendelenburg position

is supine with the head lower than the feet, which can cause blood flow to the head and increased intracranial pressure; it is not suitable for sigmoidoscopy.

C. Prone position is lying face down, which is not suitable for sigmoidoscopy.

The correct answer is choice B. Aprepitant is an antiemetic medication used to prevent nausea and vomiting associated with chemotherapy. Choice A is incorrect because decreased dysrhythmias is not a therapeutic effect of aprepitant. Choice C is incorrect because decreased incisional pain is not a therapeutic effect of aprepitant. Choice D is incorrect because absence of dizziness is not a therapeutic effect of aprepitant. Choice A is not correct because decreased dysrhythmias is not a therapeutic effect of aprepitant. Choice C is not correct because decreased incisional pain is not a therapeutic effect of aprepitant. Choice D is not correct because absence of dizziness is not a therapeutic effect of aprepitant.
