Nursing Elites

1. A client with chronic kidney disease is being assessed. Which of the following laboratory values would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Serum potassium of 6.5 mEq/L
• C. Blood urea nitrogen (BUN) of 45 mg/dL
• D. Hemoglobin of 10 g/dL

Correct answer: B

Rationale: In a client with chronic kidney disease, elevated serum potassium levels (hyperkalemia) are the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias. Monitoring and managing serum potassium levels are crucial in patients with kidney disease to prevent severe complications. While elevated creatinine (Choice A) and BUN (Choice C) are indicative of impaired kidney function, hyperkalemia poses a more immediate threat to the client's health. Hemoglobin levels (Choice D) can be affected by chronic kidney disease but are not as acutely dangerous as severe hyperkalemia.

2. The patient is receiving chemotherapy for breast cancer. Which of the following laboratory values would be most important to monitor?

• A. White blood cell count
• B. Hemoglobin level
• C. Serum creatinine
• D. Blood glucose level

Correct answer: A

Rationale: Monitoring the white blood cell count is crucial when a patient is undergoing chemotherapy for breast cancer. Chemotherapy can lead to neutropenia, a condition of low white blood cell count, which significantly increases the risk of infections. Monitoring white blood cell count helps healthcare providers intervene promptly to prevent severe infections. Hemoglobin level, while important in assessing oxygen-carrying capacity, is not the priority in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer.

3. 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.

4. A home health nurse is teaching a new caregiver how to care for a client who has had a tracheostomy for 1 year. Which of the following instructions should the nurse include?

• A. Use tracheostomy covers when going outdoors.
• B. Maintain sterile technique when performing tracheostomy care.
• C. Do not remove the outer cannula for routine cleaning.
• D. Clean around the stoma with normal saline.

Correct answer: A

Rationale: The correct answer is to use tracheostomy covers when going outdoors. This instruction is important as it helps protect the airway from dust and other particles, reducing the risk of infection or irritation. Choice B is incorrect because maintaining sterile technique is crucial during tracheostomy care to prevent infections, but it is not the most pertinent instruction in this scenario. Choice C is incorrect as removing the outer cannula is not a routine cleaning procedure and should only be done by healthcare professionals when necessary. Choice D is incorrect because cleaning around the stoma with normal saline is not recommended as it can cause irritation to the skin and stoma site.

5. While a client is receiving total parenteral nutrition (TPN), which of the following actions should the nurse take?

• A. Monitor the client's blood glucose level every 4 hours.
• B. Change the TPN tubing every 72 hours.
• C. Weigh the client daily.
• D. Change the TPN bag every 24 hours.

Correct answer: D

Rationale: The correct action is to change the TPN bag every 24 hours to reduce the risk of infection. Changing the TPN tubing every 72 hours (Choice B) may increase the risk of contamination. Monitoring the client's blood glucose level every 4 hours (Choice A) is important but not specific to TPN administration. Weighing the client daily (Choice C) is essential for monitoring fluid status but is not directly related to TPN administration.
