Nursing Elites

1. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?

• A. Serum potassium
• B. Serum calcium
• C. Serum albumin
• D. Serum sodium

Correct answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

2. The client is being taught how to use a peak flow meter. The nurse explains that this device should be used to:

• A. Determine oxygen saturation
• B. Measure forced expiratory volume
• C. Monitor the atmosphere for the presence of allergens
• D. Provide metered doses for inhaled bronchodilator

Correct answer: B

Rationale: A peak flow meter is used to measure forced expiratory volume, which helps in monitoring asthma. This measurement provides valuable information about how well the client's lungs are functioning and how narrow their airways are. Choice A is incorrect because determining oxygen saturation is typically done using a pulse oximeter. Choice C is incorrect as a peak flow meter is not used to monitor the atmosphere for allergens but rather to assess lung function. Choice D is incorrect as providing metered doses for inhaled bronchodilators is the function of a metered-dose inhaler, not a peak flow meter.

3. A healthcare professional is caring for a client who has pharyngeal diphtheria. Which of the following types of transmission precautions should the healthcare professional initiate?

• A. Contact
• B. Droplet
• C. Airborne
• D. Protective

Correct answer: B

Rationale: The correct answer is B: Droplet. Droplet precautions are required for infections that spread via droplets larger than 5 microns in diameter, such as pharyngeal diphtheria. Contact precautions are used for diseases that spread by direct or indirect contact. Airborne precautions are for diseases that spread through small particles in the air. Protective precautions are not a standard precautionary measure for specific infections like pharyngeal diphtheria.

4. A healthcare professional is admitting a client who has tuberculosis. Which of the following types of transmission precautions should the healthcare professional plan to initiate?

• A. Contact
• B. Droplet
• C. Airborne
• D. Protective environment

Correct answer: C

Rationale: Tuberculosis is transmitted through airborne particles, so airborne precautions are necessary to prevent the spread of the disease. Airborne precautions (Choice C) involve measures such as negative pressure rooms and N95 respirators to prevent the transmission of infectious agents that remain infectious over long distances when suspended in the air. Contact precautions (Choice A) are used for diseases that spread through direct contact with the patient or their environment. Droplet precautions (Choice B) are for diseases transmitted through respiratory droplets, typically over short distances. Protective environment (Choice D) is used for clients who are immunocompromised to protect them from environmental pathogens, not for diseases like tuberculosis that spread through the air.

5. A healthcare professional is preparing to perform a sterile dressing change for a client. Which of the following actions should the healthcare professional plan to take?

• A. Don sterile gloves after opening sterile dressing supplies
• B. Set up the sterile field at waist level
• C. Consider the entire border of the sterile field as contaminated
• D. Place the cap of a sterile solution inside the sterile field

Correct answer: B

Rationale: Setting up the sterile field at waist level is crucial to maintaining its sterility during a dressing change. Choice A is incorrect because sterile gloves should be worn after opening sterile dressing supplies to prevent contamination. Choice C is incorrect as the entire border of the sterile field should be considered contaminated to maintain sterility. Choice D is incorrect because the cap of a sterile solution should never be placed inside the sterile field to prevent contamination.
