Answer and Explanation

C: This is a standard bowel preparation instruction for colonoscopy to ensure a clear view of the colon during the procedure.

Correct Answer is D

Explanation

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.

A. Decreased dysrhythmias B. Absence of nausea C. Decreased incisional pain D. Absence of dizziness

Correct Answer is B

Explanation

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.
