Nursing Elites

1. A healthcare professional is reviewing the results of serum laboratory studies of a client with suspected hepatitis. Which increased parameter is interpreted as the most specific indicator of this disease?

• A. Hemoglobin
• B. Serum bilirubin
• C. Blood urea nitrogen (BUN)
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: B

Rationale: Serum bilirubin is the most specific indicator of hepatitis as it reflects liver dysfunction. Hemoglobin, blood urea nitrogen (BUN), and erythrocyte sedimentation rate (ESR) are not specific to hepatitis. Hemoglobin measures the oxygen-carrying capacity of red blood cells, BUN evaluates kidney function, and ESR is a nonspecific marker of inflammation or infection.

2. A client who has just undergone a skin biopsy is listening to discharge instructions from the nurse. The nurse determines that the client has misunderstood the directions if the client indicates that as part of aftercare he plans to:

• A. Use the antibiotic ointment as prescribed
• B. Return in 7 days to have the sutures removed
• C. Apply cool compresses to the site twice a day for 20 minutes
• D. Call the physician if excessive drainage from the wound occurs

Correct answer: C

Rationale: The correct answer is C. Applying cool compresses to the site twice a day for 20 minutes is not a recommended aftercare practice for a skin biopsy. After a skin biopsy, it is important to keep the dressing dry and in place for a minimum of 8 hours. Choice A is correct as using the antibiotic ointment as prescribed is a common post-biopsy instruction to prevent infection. Choice B is also correct as returning in 7 days to have the sutures removed is part of the typical follow-up care after a skin biopsy. Choice D is correct as it is important to call the physician if excessive drainage from the wound occurs to prevent complications.

3. A client who was in a motor vehicle collision was admitted to the hospital, and the right knee was placed in skeletal traction. The nurse has documented this nursing diagnosis in the client's medical record: 'Potential for impairment of skin integrity related to immobility from traction.' Which nursing intervention is indicated based on this diagnosis statement?

• A. Release the traction every 4 hours to provide skin care.
• B. Turn the client for back care while suspending traction.
• C. Provide back and skin care while maintaining the traction.
• D. Give back care after the client is released from traction.

Correct answer: C

Rationale: The correct nursing intervention indicated based on the nursing diagnosis 'Potential for impairment of skin integrity related to immobility from traction' is to provide back and skin care while maintaining the traction. This intervention is crucial for maintaining the client's skin integrity and preventing potential complications. Releasing the traction every 4 hours (Choice A) may disrupt the treatment plan and compromise the effectiveness of traction. Turning the client for back care while suspending traction (Choice B) does not address the need for skin care while the client is in traction. Giving back care after the client is released from traction (Choice D) neglects the immediate need to prevent skin impairment while in traction. Therefore, providing back and skin care while maintaining the traction (Choice C) is the most appropriate intervention in this scenario.

4. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

• A. To broaden the antibacterial spectrum.
• B. To decrease bacterial resistance.
• C. To improve the taste.
• D. To minimize toxic effects.

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

5. The client admitted with peripheral vascular disease (PVD) asks the nurse why her legs hurt when she walks. The nurse bases a response on the knowledge that the main characteristic of PVD is:

• A. Decreased blood flow.
• B. Increased blood flow.
• C. Slow blood flow.
• D. Thrombus formation.

Correct answer: A

Rationale: The correct answer is A: 'Decreased blood flow.' In peripheral vascular disease (PVD), there is a narrowing or blockage of blood vessels, leading to reduced blood flow to the extremities. This decreased blood flow results in inadequate oxygen supply to the muscles, causing pain, especially during physical activity when oxygen demand increases. Choice B, 'Increased blood flow,' is incorrect because PVD is characterized by impaired blood circulation rather than increased flow. Choice C, 'Slow blood flow,' is not precise as PVD involves a more significant reduction in blood flow. Choice D, 'Thrombus formation,' is related to the formation of blood clots within vessels, which can be a complication of PVD but is not its main characteristic.
