Nursing Elites

1. The client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value is most concerning?

• A. Serum potassium of 6.0 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Serum calcium of 8.0 mg/dL
• D. Hemoglobin of 10 g/dL

Correct answer: A

Rationale: A serum potassium level of 6.0 mEq/L is most concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications such as arrhythmias and cardiac arrest. Immediate intervention is required to lower potassium levels. Choice B, serum creatinine of 2.5 mg/dL, is elevated but expected in ESRD due to impaired kidney function. Choice C, serum calcium of 8.0 mg/dL, is within the normal range and not typically a priority in this situation. Choice D, hemoglobin of 10 g/dL, is slightly low but not an immediate concern for a client scheduled for hemodialysis unless significantly lower and causing severe symptoms.

2. When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?

• A. Avoid administration of oxygen at high levels for extended periods.
• B. Increase oxygen flow rate if the child is still tachypneic.
• C. Reduce oxygen levels gradually after symptoms improve.
• D. Humidify the oxygen to prevent drying of mucous membranes.

Correct answer: A

Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.

3. A client who is at 10-weeks gestation calls the clinic because she has been vomiting for the past 24 hours. The nurse determines that the client has no fever. Which instructions should the nurse give to this client?

• A. Come to the clinic to be seen by a healthcare provider
• B. Increase your fluid intake and rest at home
• C. Take over-the-counter antiemetics as needed
• D. Monitor your symptoms and call if they worsen

Correct answer: A

Rationale: The correct answer is to advise the client to come to the clinic to be seen by a healthcare provider. Persistent vomiting during pregnancy can lead to dehydration, which requires medical evaluation. Choice B is incorrect because solely increasing fluid intake and resting at home may not be sufficient to address the potential dehydration and underlying causes of vomiting. Choice C is not recommended without medical evaluation, as over-the-counter antiemetics should be used under healthcare provider guidance during pregnancy. Choice D is not the best option here because with persistent vomiting and risk of dehydration, immediate medical assessment is crucial to ensure the well-being of both the client and the fetus.

4. A client with a history of heart failure presents to the clinic with nausea, vomiting, yellow vision, and palpitations. Which finding is most important for the nurse to assess for this client?

• A. Assess distal pulses and signs of peripheral edema
• B. Determine the client's level of orientation and cognition
• C. Obtain a list of medications taken for cardiac history
• D. Ask the client about exposure to environmental heat

Correct answer: C

Rationale: The correct answer is to obtain a list of medications taken for cardiac history. The client's presentation is indicative of digitalis toxicity, commonly associated with medications like digoxin (Lanoxin) used in heart failure treatment. Understanding the client's medication history, particularly the use of digoxin, is crucial in confirming and managing digitalis toxicity. Assessing distal pulses and signs of peripheral edema (Choice A) may be relevant in heart failure but are not the priority in this case. Determining the client's level of orientation and cognition (Choice B) and asking about exposure to environmental heat (Choice D) are not directly related to the client's current symptoms and are less pertinent in this scenario.

5. A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which laboratory value should be closely monitored?

• A. Serum creatinine of 2.0 mg/dL
• B. Serum sodium of 135 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Blood glucose of 150 mg/dL

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L should be closely monitored in a client with chronic heart failure as it may indicate hyperkalemia, requiring intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias in patients with heart failure. Serum creatinine (Choice A) is important to monitor for kidney function but is not the priority in this case. Serum sodium (Choice B) and blood glucose (Choice D) levels are not typically the primary focus when assessing a client with heart failure presenting with respiratory symptoms and crackles in the lungs.
