Nursing Elites

1. A client with chronic kidney disease is experiencing hyperkalemia. Which medication should the LPN/LVN anticipate being prescribed to lower the client's potassium level?

• A. Furosemide (Lasix)
• B. Sodium polystyrene sulfonate (Kayexalate)
• C. Calcium gluconate
• D. Albuterol (Proventil)

Correct answer: B

Rationale: The correct answer is B: Sodium polystyrene sulfonate (Kayexalate). Kayexalate is commonly used to lower potassium levels in clients with hyperkalemia by exchanging sodium ions for potassium ions in the large intestine, leading to the elimination of excess potassium from the body. Choice A, Furosemide (Lasix), is a loop diuretic that helps with fluid retention but does not directly lower potassium levels. Choice C, Calcium gluconate, is used to treat calcium deficiencies and does not impact potassium levels. Choice D, Albuterol (Proventil), is a bronchodilator used to treat respiratory conditions and does not affect potassium levels. Therefore, the LPN/LVN should anticipate the prescription of Kayexalate to address the client's hyperkalemia.

2. When replacing a client's surgical dressing, what should the nurse do?

• A. Don sterile gloves to remove the old dressing
• B. Wash hands thoroughly before removing the old dressing
• C. Use sterile gloves to remove the old dressing
• D. Apply a new dressing before removing the old one

Correct answer: C

Rationale: When replacing a client's surgical dressing, the nurse should use sterile gloves to remove the old dressing. Sterile technique is essential to prevent introducing infection to the wound. Choice A is incorrect because clean gloves are not sufficient; sterile gloves are necessary to maintain asepsis. Choice B, washing hands, is an important step before and after the procedure to maintain hand hygiene, but sterile gloves are required during the dressing change. Choice D is incorrect because a new dressing should only be applied after the old one has been removed to prevent contamination and ensure proper wound care.

3. A healthcare professional is caring for a group of clients. Which of the following measures should the professional take to prevent the spread of infection?

• A. Place a client with TB in a room with negative pressure airflow
• B. Use a disposable gown for contact precautions
• C. Place a client with MRSA in a private room
• D. Use a mask for clients with influenza

Correct answer: A

Rationale: Tuberculosis is an airborne infection, and placing a client with TB in a room with negative pressure airflow helps prevent the spread of the infection by containing the pathogens. This measure is crucial as it prevents the dissemination of TB droplet nuclei to other areas. Choice B, using a disposable gown for contact precautions, is important for preventing the transmission of infections spread by direct or indirect contact. Choice C, placing a client with MRSA in a private room, is essential to prevent the spread of MRSA through contact with others. Choice D, using a mask for clients with influenza, helps prevent the spread of influenza through respiratory droplets. However, negative pressure airflow is specifically required for airborne infections like TB, making it the most appropriate choice in this scenario.

4. At the surgical scrub sink, a surgical nurse demonstrated the proper surgical handwashing technique by scrubbing:

• A. With her hands held lower than her elbows
• B. With her hands held higher than her elbows
• C. With her hands in a fist position
• D. With hands placed on her chest

Correct answer: B

Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.

5. A nurse is assessing the heart sounds of a client who has developed chest pain that becomes worse with inspiration. The nurse auscultates a high-pitched scratching sound during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border. Which of the following heart sounds should the nurse document?

• A. Pericardial friction rub
• B. Mitral stenosis
• C. Aortic regurgitation
• D. Tricuspid stenosis

Correct answer: B

Rationale: The correct answer is B: Mitral stenosis. A high-pitched scratching sound heard during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border indicates mitral stenosis, not a pericardial friction rub. Pericardial friction rub is a to-and-fro, grating, or scratching sound due to inflamed pericardial surfaces rubbing together, typically heard in early diastole and late systole. Aortic regurgitation and tricuspid stenosis would present with different auscultatory findings compared to the described scenario, making them incorrect choices in this context.
