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.

Correct Answer is C
Explanation
Choice A rationale
Administering the prescribed antibiotic early might not be the most immediate action. While antibiotics can help treat an infection, it’s crucial to first confirm the presence of an infection before starting antibiotic therapy.
Choice B rationale
Applying a sterile dressing to the area is important, but it’s not the priority nursing action. Dressings help protect the wound from further contamination, but they do not address the underlying issue of a potential infection.
Choice C rationale
Reporting the finding to the care provider is the priority nursing action. The symptoms described - a new foul odor coming from the incision, which is erythematous, tender, and warm to the touch - suggest a possible infection. Immediate reporting allows for prompt evaluation and treatment, which is crucial in preventing further complications.
Choice D rationale
Obtaining a culture of the incision might be necessary to identify the specific causative agent of the infection, but it’s not the priority action. It’s more important to first report the findings to the care provider.
Correct Answer is C
Explanation
Choice A rationale
Heparin does not actually thin the blood or make it less thick. Instead, it works by increasing the activity of antithrombin, a protein that inhibits blood clotting. This prevents new clots from forming and existing clots from growing larger.
Choice B rationale
Heparin does not dissolve clots or decrease the formation of platelets. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa, two key players in the blood clotting process.
Choice C rationale
This statement is accurate. Heparin does not thin the blood; instead, it prevents new clots from forming and existing clots from growing larger. It does this by increasing the activity of antithrombin, which in turn inactivates thrombin and factor Xa.
Choice D rationale
Heparin does not decrease the number of platelets or make the blood flow more easily. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa.
