Practice HESI Fundamentals Exam

Correct Answer: C

Rationale: The correct first action for the school nurse to take when a child is injured and appears to have a fractured leg is to assess the child and the extent of the injury. This initial assessment is crucial to determine the severity of the injury before proceeding with further interventions. Option A, calling for emergency transport, should only be done after assessing the extent of the injury. Option B, immobilizing the limb and joints, is important but should come after the initial assessment. Option D, applying cold compresses, is not recommended for suspected fractures as it can exacerbate swelling and pain.

Correct Answer: B

Rationale: The correct instruction to include in the teaching plan for a client who had a hemiarthroplasty of the left hip is to 'Place a pillow between your knees while lying in bed to prevent hip dislocation.' This technique helps maintain proper hip alignment and prevents dislocation during the postoperative recovery period. Choice A is incorrect because bending at the waist to reach items on the floor can strain the hip joint and is not recommended following hip surgery. Choice C is incorrect because using a walker alone without assistance can increase the risk of falls and injury, especially in the immediate postoperative period. Choice D is incorrect because pain medication should be taken as prescribed by the healthcare provider, not specifically timed after physical therapy sessions.

Correct Answer: A

Rationale: The priority action for the nurse after completing the assessment and review of systems for an older adult client is to orient them to their room. This is crucial for ensuring the client's comfort and safety in the new environment. While reviewing medical prescriptions and developing a plan of care are important aspects of the admission process, they can be done after the client has been oriented to their room.

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.

Correct Answer: D

Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.
