Correct Answer is D

Explanation

Choice A reason:

Face is incorrect: Facial skin colour can vary for many reasons, but it may not be the best indicator of jaundice in individuals with dark skin.

Choice B reason

Shoulders is incorrect: The shoulders are not typically indicative of jaundice.

Choice C reason:

Palm of the hands is incorrect: While the palm of the hands can sometimes show yellowing in cases of jaundice, it is less reliable than observing the sclera.

Choice D reason:

Sclera is the best location. In individuals with darker skin tones, yellowish discoloration of the skin due to jaundice can be more challenging to detect. However, the sclera of the eyes can still show noticeable yellowing, making it a reliable location for assessing jaundice in individuals with both light and dark skin.

A. Evaluate dietary intake for a client who has anorexia. B. Measure the vital signs of a client who just returned from the PACU C. Arrange the lunch tray for a client who has a hip fracture. D. Assess I&O for a client who is receiving dialysis.

Correct Answer is C

Explanation

A. Incorrect. Evaluating dietary intake requires nursing judgment and knowledge of nutrition and eating disorders. This task should not be delegated to an AP.

B. Incorrect. Measuring vital signs of a postoperative client requires nursing assessment and monitoring for complications. This task should not be delegated to an AP.

C. Correct. Arranging the lunch tray for a client who has a hip fracture is a routine task that does not require nursing skills or judgment. This task can be delegated to an AP.

D. Incorrect. Assessing I&O for a client who is receiving dialysis requires nursing knowledge of fluid and electrolyte balance and renal function. This task should not be delegated to an AP.
