Explanation

The other options are not correct because:
B. A positive Babinski's reflex is a normal finding in newborns that indicates intact neurological function. It is elicited by stroking the sole of the foot and observing the fanning of the toes.
C. A negative Ortolani's sign is a normal finding in newborns that indicates no hip dislocation or dysplasia. It is elicited by abducting the hips and feeling for any clicking or clunking sensation.
D. A large sacral "stork bite" is a common benign birthmark that appears as a reddish patch on the lower back or nape of the neck. It usually fades within the first year of life and does not require any treatment.
Correct Answer is B
Explanation
Tell the client that the PN will verify that the dispensed medication is the valid prescription. Choice A rationale:
Explaining that the healthcare provider probably prescribed a different medication while the client is hospitalized (Choice A) may create confusion or concern for the client. It is essential to reassure the client and take appropriate action to address the discrepancy in the appearance of the medication.
Choice C rationale:
Explaining that the pharmacy often substitutes generic equivalents for more expensive brands (Choice C) is not applicable in this situation since the client is expressing concern about the appearance of the medication prescribed by the healthcare provider, not a substitution by the pharmacy.
Choice D rationale:
Telling the client that he is probably confused since being hospitalized tends to disorient clients (Choice D) is dismissive of the client's concerns. It is crucial to acknowledge the client's observation and address the issue professionally.
