A client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the LPN monitor closely while the client is taking this medication?
- A. Sodium
- B. Potassium
- C. Calcium
- D. Magnesium
Correct Answer: B
Rationale: The LPN should monitor potassium levels closely while the client is taking furosemide (Lasix) due to the medication's potential to cause hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Hypokalemia can result in serious complications such as cardiac dysrhythmias. Monitoring sodium levels (choice A) is important but not as critical as monitoring potassium in this context. Calcium (choice C) and magnesium (choice D) levels are not typically affected by furosemide and are not the priority for monitoring in this scenario.

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.
An adult client is found to be unresponsive on morning rounds. After checking for responsiveness and calling for help, the next action that should be taken by the nurse is to:
- A. Check the carotid pulse
- B. Deliver 5 abdominal thrusts
- C. Give 2 rescue breaths
- D. Open the client's airway
Correct Answer: D
Rationale: In this scenario, the priority is to ensure the client has a clear airway to facilitate breathing. After verifying unresponsiveness and calling for help, the nurse should open the client's airway to aid in maintaining ventilation. Checking the carotid pulse (Choice A) may be important but comes after ensuring a clear airway. Delivering abdominal thrusts (Choice B) is indicated for choking, not for an unresponsive client. Giving rescue breaths (Choice C) is also important but only after the airway has been established.
A nurse is reviewing the correct use of a fire extinguisher with a client. Which of the following actions should the nurse direct the client to take first?
- A. Remove the safety pin from the extinguisher.
- B. Aim the extinguisher at the base of the fire.
- C. Squeeze the handle to release the extinguishing agent.
- D. Sweep the extinguisher from side to side.
Correct Answer: A
Rationale: The correct first step in using a fire extinguisher is to remove the safety pin. This action enables the extinguisher to be activated and used effectively. Choice B, aiming the extinguisher at the base of the fire, comes after removing the safety pin. Choice C, squeezing the handle to release the extinguishing agent, and choice D, sweeping the extinguisher from side to side, are subsequent steps in using a fire extinguisher and should follow removing the safety pin.
A healthcare professional is preparing to admit a client suspected of having pulmonary tuberculosis. Which of the following actions should the healthcare professional plan to perform first?
- A. Implement airborne precautions.
- B. Obtain a sputum culture.
- C. Administer antituberculosis medications.
- D. Recommend a screening test for close contacts.
Correct Answer: A
Rationale: The initial priority when admitting a client suspected of having pulmonary tuberculosis is to implement airborne precautions to prevent the spread of the disease. Airborne precautions include wearing a mask and placing the client in a negative pressure room. Obtaining a sputum culture is essential for confirming the diagnosis, but ensuring infection control measures come first to protect others. Administering antituberculosis medications is important but should be initiated after implementing necessary precautions. Recommending a screening test for close contacts is relevant but is a secondary concern compared to immediate infection control measures.
While assisting a client with a meal, the client suddenly grabs at their neck with both hands and appears frightened. The appropriate nursing action is to:
- A. Ask the client if they are choking
- B. Perform abdominal thrusts
- C. Call for emergency help
- D. Check the client's airway
Correct Answer: A
Rationale: The correct action when a client suddenly grabs at their neck and appears frightened is to ask if they are choking. This allows the nurse to gather more information from the client directly. Performing abdominal thrusts (choice B) should only be done if the client is unable to speak, cough, or breathe. Calling for emergency help (choice C) should be done after assessing the situation and confirming choking. Checking the client's airway (choice D) is important but should come after confirming that the client is choking.
