HESI LPN
Adult Health 2 Final Exam
1. The nurse is caring for a client who has just returned from surgery with a urinary catheter in place. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs)?
- A. Irrigate the catheter daily
- B. Ensure the catheter bag is always below bladder level
- C. Change the catheter every 48 hours
- D. Administer prophylactic antibiotics
Correct answer: B
Rationale: The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.
2. During a tonic-clonic seizure, what is the nurse's priority intervention?
- A. Insert an oral airway
- B. Administer oxygen via nasal cannula
- C. Restrain the client's arms and legs
- D. Protect the client's head from injury
Correct answer: D
Rationale: During a tonic-clonic seizure, the nurse's priority intervention is to protect the client's head from injury. This is crucial to prevent trauma, as head injuries can be severe during a seizure. Inserting an oral airway may cause injury or obstruction during the seizure and is not recommended. Administering oxygen via nasal cannula can be done after ensuring the client's safety. Restraining the client's arms and legs is also not recommended as it can lead to further injury or harm.
3. When taking blood pressure at the brachial artery, the nurse should place the client's arm in which position?
- A. Slightly above the level of the heart
- B. At the level of the heart
- C. At a level of comfort for the client
- D. Below the level of the heart
Correct answer: B
Rationale: When taking blood pressure at the brachial artery, it is crucial to place the client's arm at the level of the heart to ensure accurate measurement. Placing the arm above or below the heart level can lead to incorrect readings. Option A, placing the arm slightly above the heart level, would result in falsely lower blood pressure readings as gravity would assist in a lower value. Option C, placing the arm at a level of comfort for the client, may not align with the standardized technique required for accurate blood pressure assessment. Option D, placing the arm below the level of the heart, would likely yield falsely higher blood pressure readings due to increased hydrostatic pressure pushing the blood against gravity.
4. The nurse is teaching a client with diabetes about foot care. Which instruction is most important to prevent complications?
- A. Soak feet in warm water daily
- B. Apply moisturizer between the toes
- C. Wear cotton socks
- D. Inspect feet daily for cuts or sores
Correct answer: D
Rationale: The correct answer is D: Inspect feet daily for cuts or sores. Daily foot inspection is crucial for clients with diabetes to detect early signs of injury or infection. Soaking feet in warm water daily (choice A) can lead to skin maceration, making the skin more susceptible to breakdown. Applying moisturizer between the toes (choice B) can increase moisture and the risk of fungal infections. While wearing cotton socks (choice C) is beneficial for diabetic foot care, it is not as crucial as daily foot inspections to prevent complications.
5. What is the primary function of neutrophils?
- A. Heparin secretion
- B. Transport oxygen
- C. Phagocytotic action
- D. Antibody formation
Correct answer: C
Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
