HESI Fundamentals Practice Questions

Correct Answer: D

Rationale: The correct answer is 'Upper arm circumference.' Upper arm circumference is a better indicator of total muscle mass in adolescents compared to height, weight, or triceps skinfold thickness. Triceps skinfold thickness primarily reflects subcutaneous fat, while weight and height are not specific to muscle mass. Upper arm circumference directly measures the muscle mass in the upper arm and can provide a more accurate assessment in this context. Therefore, choices A, B, and C are incorrect because they do not directly reflect total muscle mass in adolescents.

Correct Answer: A

Rationale: Identifying the client using two identifiers is the crucial first step to ensure correct patient identification before any procedure. This process helps prevent errors and ensures that the right procedure is performed on the right patient. Confirming the client's identity is the top priority before addressing other aspects such as fasting status, allergies, or explaining the procedure. While confirming fasting status and checking for allergies are important, they are secondary to confirming the client's identity. Explaining the procedure to the client is also essential but should occur after ensuring proper identification.

Correct Answer: D

Rationale: The correct answer is D because there is no need to wait 72 hours before allowing the child to stand. The synthetic cast does not affect weight-bearing capacity, and standing can be done as tolerated. Choice A is incorrect because keeping the cast covered can lead to damage or accidents. Choice B is acceptable as applying an ice pack can help relieve itching. Choice C is also correct as elevating the cast on pillows can help reduce swelling and promote comfort during rest.

Correct Answer: B

Rationale: The correct answer is B because as a witness, the nurse's primary responsibility is to confirm that the signature on the preoperative consent form belongs to the client. The nurse is not confirming the client's understanding of the procedure (Choice A), but rather the authenticity of the signature. Choice C is incorrect because the nurse is not responsible for verifying that the procedure has been explained, but rather confirming the client's signature. Similarly, Choice D is incorrect because the nurse's role as a witness is not to ensure the client is aware of potential complications, but to verify the signature.
