Practice HESI Fundamentals Exam

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 nurse should focus on decreased pain sensation and increased risk of skin impairment due to the patient's conditions. Peripheral neuropathy can lead to decreased pain sensation, making the patient more prone to injuries without realizing it. Additionally, the combination of circulatory insufficiency, peripheral neuropathy, and urinary incontinence can increase the risk of skin breakdown and impaired healing. Choices B, C, and D are incorrect because they do not address the specific issues related to the patient's diagnoses and symptoms.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to carefully remove the gloves and follow with hand hygiene. This is important to prevent potential contamination and maintain infection control practices. Option B is incorrect because cleaning hands later may lead to the spread of potential contaminants. Option C is unnecessary as starting over is not required if proper hand hygiene is performed. Option D is not sufficient in ensuring proper hygiene after a blood spill, as hand sanitizer may not effectively remove all contaminants.

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: B

Rationale: Assessing for impaction is crucial as it is a common cause of constipation and abdominal discomfort. In this scenario, the patient's symptoms of chronic constipation and no bowel movement for five days despite trying home remedies indicate a potential impaction that needs to be assessed. Evaluating stool samples for blood, determining the home remedies used, or obtaining a list of prescribed medications, while potentially relevant, are not as urgent as assessing for impaction in this situation.
