A newly admitted client has been prescribed trimethoprim-sulfamethoxazole.
The nurse understands that this medication is contraindicated based on which lab result?
Serum fasting glucose of 101 mg/dL.
Platelets of 160,000 uL.
Hemoglobin of 13.6 g/dL.
Serum creatinine of 2.5 mg/dL.
The Correct Answer is D
Choice A rationale
A serum fasting glucose of 101 mg/dL is slightly above the normal range (70-100 mg/dL), indicating a possible prediabetes condition. However, it is not a contraindication for trimethoprim-sulfamethoxazole.
Choice B rationale
A platelet count of 160,000 uL is within the normal range (150,000-450,000 uL). Therefore, it is not a contraindication for trimethoprim-sulfamethoxazole.
Choice C rationale
A hemoglobin level of 13.6 g/dL is within the normal range for both men (13.5-17.5 g/dL) and women (12.0-15.5 g/dL). Thus, it is not a contraindication for trimethoprim-sulfamethoxazole.
Choice D rationale
A serum creatinine level of 2.5 mg/dL is above the normal range (0.6-1.2 mg/dL for men, 0.5- 1.1 mg/dL for women), indicating impaired kidney function. Trimethoprim-sulfamethoxazole is contraindicated in patients with severe renal insufficiency.

Related Questions
Correct Answer is C
Explanation
Wearing closed-toe shoes when walking can help protect the feet from injuries. However, it does not directly address the issue of numbness and reduced sensation due to severe peripheral neuropathy.
Choice B rationale
Soaking feet daily to remove pathogens can help maintain hygiene, but it does not directly address the issue of numbness and reduced sensation due to severe peripheral neuropathy.
Choice C rationale
Examining your feet daily is a crucial intervention for patients with severe peripheral neuropathy. Due to the numbness and reduced sensation, patients might not notice injuries or changes in their feet. Regular self-examination can help detect any abnormalities early, preventing further complications.
Choice D rationale
Using lotion on all areas of the feet for moisture can help prevent dryness and cracking of the skin, but it does not directly address the issue of numbness and reduced sensation due to severe peripheral neuropathy.
Correct Answer is C
Explanation
Choice A rationale
Reddish feet when put down could be a sign of dependent rubor, a condition that occurs due to peripheral arterial disease (PAD). When the legs are in a dependent (downward) position, gravity aids in delivering blood to the area, causing a reddish color. However, this is a common symptom of PAD and does not require immediate intervention.
Choice B rationale
Loss of hair on the feet and legs is another symptom of PAD1. This happens because inadequate blood flow deprives the hair follicles of the nutrients they need to grow. While this symptom indicates worsening PAD, it does not warrant immediate intervention.
Choice C rationale
Applying a heating pad to cold legs could lead to burns because PAD can cause loss of sensation in the legs. This warrants immediate intervention to prevent injury.
Choice D rationale
Leg pain during walking, also known as claudication, is a common symptom of PAD1. This happens because the muscles are not getting enough oxygen due to reduced blood flow.
However, this symptom does not require immediate intervention but should be evaluated further.
