Practice HESI Fundamentals Exam

Correct Answer: D

Rationale: The first action the nurse should implement is to determine the size and depth of the skin breakdown over the sacral area. This initial assessment will provide crucial information on the extent of the damage and guide appropriate care interventions. Option A is not the priority in this scenario as the immediate concern is addressing the existing skin breakdown. Option B, completing a functional assessment, is important but should come after addressing the acute issue of skin breakdown. Option C, applying a barrier ointment, may be beneficial later but does not address the primary need of assessing the extent of the current skin damage.

Correct Answer: A

Rationale: The Romberg test is used to assess a client's balance by evaluating their ability to maintain a steady posture with eyes closed. The heel-to-toe walk is another assessment that tests balance by assessing gait and coordination. The Snellen test is used to assess visual acuity and is unrelated to balance. Testing spinal accessory function involves assessing the movement of the head and shoulders and is not directly related to balance assessment.

Correct Answer: A

Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg � 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.

Correct Answer: A

Rationale: The correct answer is A: Vitamin C and Zinc. Vitamin C is essential for collagen synthesis, which is important for wound healing. Zinc plays a crucial role in immune function and also aids in wound healing. Vitamin B12 and Calcium (Choice B) are not directly associated with wound healing properties. Vitamin D and Iron (Choice C) are important for overall health but are not specifically targeted for wound healing. Vitamin A and Potassium (Choice D) do not have direct wound healing properties and are not the best choices to promote wound healing and fight infection.

Correct Answer: B

Rationale: In a client with moderate persistent asthma experiencing a drop in peak flow and chest tightness post-operatively, the first action the nurse should take is to administer the PRN dose of Albuterol. Albuterol is a short-acting bronchodilator that helps relieve bronchospasm and improve breathing. Notifying the healthcare provider (choice A) can be done after initiating immediate treatment with Albuterol. Applying oxygen (choice C) may be necessary but addressing the bronchospasm with Albuterol is the priority. Repeating the peak flow reading (choice D) can be considered after administering Albuterol to assess the response to treatment.
