HESI Fundamentals Exam

Correct Answer: A

Rationale: When a nurse suspects pediculosis capitis (head lice) upon noticing movement in the patient's hair, the correct action is to use gloves to inspect the hair. This protects the nurse from potential self-infestations. Applying a lindane-based shampoo immediately (Choice B) is not the first action, as diagnosis and confirmation are necessary before treatment. Shaving the patient's hair off (Choice C) is an extreme measure and is unnecessary at this stage. Ignoring the movement and continuing (Choice D) is negligent and can lead to the spread of infestation.

Correct Answer: D

Rationale: No special preparation is required for a Venous Doppler evaluation. Option A is incorrect because there is no need for the client to be NPO (nothing by mouth) before this test. Option B is incorrect as sedative medication is not typically administered for a Venous Doppler evaluation. Option C is incorrect as discontinuing anticoagulant therapy before the test may not be safe for a client with DVT, as it could increase the risk of developing a blood clot. Therefore, the correct answer is D.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to notify the provider about the client's decision. By informing the provider, they can discuss the client's change in decision, explore the reasons behind it, and determine the appropriate course of action. Proceeding with the transport (Choice B) without addressing the client's concerns would not respect the client's autonomy and right to make decisions about their own healthcare. Preparing the surgical site (Choice C) would be premature and inappropriate if the client no longer wishes to proceed with the surgery. While documenting the client's statement (Choice D) is important for documentation purposes, the immediate priority is to involve the provider in the decision-making process.

Correct Answer: D

Rationale: Vesicles are small fluid-filled blisters. Herpes simplex is an example of a vesicular lesion, characterized by small, fluid-filled blisters. Acne presents as comedones, papules, pustules, or nodules, not vesicles. Warts are caused by the human papillomavirus and appear as rough, raised growths. Psoriasis is a chronic autoimmune condition that results in red, scaly patches on the skin, not vesicles.

Correct Answer: B

Rationale: Drawing up insulin after warming the vial to room temperature indicates a need for further teaching, as insulin should be at room temperature for administration. Choice A is correct as rotating injection sites helps prevent lipodystrophy. Choice C is correct as pinching the skin helps ensure proper subcutaneous injection. Choice D is correct as injecting insulin at a 90-degree angle is the recommended technique for subcutaneous injections.
