Nursing Elites

1. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which laboratory value requires immediate intervention?

• A. Serum potassium of 6.5 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 2.0 mg/dL
• D. Blood glucose of 150 mg/dL

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is most concerning in a client with CKD as it indicates severe hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias. Serum sodium levels within the normal range (135 mEq/L) are not immediately concerning. Serum creatinine of 2.0 mg/dL may indicate impaired kidney function but does not require immediate intervention for hyperkalemia. Blood glucose of 150 mg/dL is within normal limits and does not directly correlate with hyperkalemia in this scenario.

2. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum sodium level of 135 mEq/L

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.

3. A client with severe COPD is receiving oxygen therapy at 2 liters per minute via nasal cannula. The client's oxygen saturation level drops to 88% during ambulation. What action should the nurse take first?

• A. Increase the oxygen flow rate to 4 liters per minute.
• B. Instruct the client to rest until the oxygen saturation improves.
• C. Discontinue ambulation and return the client to bed.
• D. Encourage the client to breathe more deeply.

Correct answer: C

Rationale: In this scenario, the client's oxygen saturation level dropping during ambulation indicates an inadequate oxygen supply. The first action the nurse should take is to discontinue ambulation and return the client to bed. This helps stabilize the oxygen level by reducing the oxygen demand placed on the client during physical activity. Increasing the oxygen flow rate without addressing the underlying issue of oxygen saturation dropping may not be effective. Instructing the client to rest is not enough to address the immediate need for stabilization of oxygen levels. Encouraging the client to breathe more deeply may not be sufficient to overcome the oxygen saturation drop caused by inadequate oxygen supply during ambulation.

4. A nurse is preparing to administer a dose of digoxin (Lanoxin) to a client with heart failure. Which assessment finding requires immediate intervention?

• A. Apical pulse of 58 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Presence of a new murmur
• D. Respiratory rate of 18 breaths per minute

Correct answer: A

Rationale: An apical pulse of 58 beats per minute is concerning when administering digoxin because digoxin can further lower the heart rate, leading to bradycardia or heart block. Immediate intervention is required to prevent potential complications. A blood pressure of 110/70 mmHg is within normal range and does not require immediate intervention in this context. The presence of a new murmur may indicate valvular issues but does not directly relate to the administration of digoxin. A respiratory rate of 18 breaths per minute is also within normal limits and is not a priority concern when administering digoxin.

5. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse monitor closely?

• A. Serum potassium
• B. Serum creatinine
• C. Serum sodium
• D. Serum chloride

Correct answer: C

Rationale: The correct answer is C: Serum sodium. In a client with chronic kidney disease (CKD) scheduled for hemodialysis, monitoring serum sodium levels closely is essential. Hemodialysis can cause rapid shifts in sodium levels, leading to electrolyte imbalances. While serum potassium (choice A) is important to monitor in CKD, it is not the most crucial before hemodialysis. Serum creatinine (choice B) is an indicator of kidney function but is not the most immediate concern before hemodialysis. Serum chloride (choice D) is not typically the primary electrolyte of concern in CKD patients before hemodialysis.
