Nursing Elites

1. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?

• A. Serum potassium of 5.5 mEq/L
• B. Blood urea nitrogen (BUN) of 40 mg/dl
• C. Serum potassium of 6.0 mEq/L
• D. Serum creatinine of 2.5 mg/dl

Correct answer: C

Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.

2. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

3. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Hemoglobin of 10 g/dL
• D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.

4. A client with chronic kidney disease (CKD) is receiving epoetin alfa (Epogen). Which laboratory value should the nurse monitor closely?

• A. Hemoglobin
• B. White blood cell count
• C. Serum potassium
• D. Serum creatinine

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client with chronic kidney disease (CKD) is receiving epoetin alfa (Epogen), monitoring serum potassium levels closely is crucial. Epoetin alfa stimulates red blood cell production, which can lead to an increase in potassium levels. Hyperkalemia is a potential risk in these clients. Monitoring hemoglobin levels (choice A) is important in assessing the effectiveness of epoetin alfa therapy, but it is not the laboratory value that poses an immediate risk related to the medication. White blood cell count (choice B) and serum creatinine (choice D) are not directly affected by epoetin alfa therapy and are not the priority laboratory values to monitor in this case.

5. A client presents at the clinic with blepharitis. What instructions should the nurse provide for home care?

• A. Use bilateral eye patches while sleeping to prevent injury to the eyes.
• B. Wear sunglasses when outdoors to prevent photophobia.
• C. Apply cold compresses to reduce inflammation.
• D. Apply warm moist compresses then gently scrub eyelids with diluted baby shampoo.

Correct answer: D

Rationale: The correct answer is D. Blepharitis is managed with warm moist compresses to help loosen debris and oils on the eyelids, followed by gentle scrubbing with a mild solution like diluted baby shampoo. This helps in controlling the condition. Choice A is incorrect as using eye patches while sleeping is not a standard recommendation for blepharitis. Choice B is incorrect as wearing sunglasses does not directly treat blepharitis but may help with light sensitivity. Choice C is incorrect as cold compresses are not typically used for blepharitis, as warm compresses are more effective in managing the condition.
