A nurse is caring for a 45-year-old male client in a medical-surgical unit who has a new prescription for cefazolin.

Exhibits

Which of the following findings should the nurse identify as contraindications to administering cefazolin? (Select all that apply.)

Allergy to penicillin

Elevated WBC count

Prescription for furosemide

Fever >38.3°C

Answer and Explanation

Correct Answer : A,C

Choice A rationale: Allergy to penicillin can be a contraindication for administering cefazolin because of potential cross-reactivity between penicillins and cephalosporins. This client’s documented allergy to penicillin with symptoms of rash and throat swelling is significant and raises concern for a potential allergic reaction to cefazolin.

Choice B rationale: Elevated WBC count indicates an ongoing infection or inflammation, which is not a contraindication for cefazolin. Instead, it suggests the need for an antibiotic like cefazolin to manage the infection.

Choice C rationale: Prescription for furosemide is relevant because combining cephalosporins like cefazolin with diuretics like furosemide can increase the risk of nephrotoxicity. It’s important to consider the client’s renal function and monitor for potential kidney damage.

Choice D rationale: Fever >38.3°C is an indication for antibiotic therapy, not a contraindication. The elevated temperature suggests an infection that needs to be treated, making cefazolin appropriate in this context.

Correct Answer is B

Explanation

Choice A rationale

Instilling a warm enema solution is not appropriate for treating malignant hyperthermia. The focus should be on cooling measures and medications.

Choice B rationale

Applying a cooling blanket is an appropriate action to help reduce the client's body temperature during malignant hyperthermia.

Choice C rationale

Administering meperidine IM is not indicated for malignant hyperthermia. The appropriate medications include dantrolene, cooling measures, and supportive care.

Choice D rationale

Ventilating the client with 100% oxygen, not 50%, is the appropriate action to ensure adequate oxygenation during malignant hyperthermia.

A. Platelets 60,000/mm³ (150,000 to 400,000/mm³). B. Ammonia 55 mcg/dL (10 to 80 mcg/dL). C. Bilirubin 1.0 mg/dL (0.3 to 1.0 mg/dL). D. Aspartate aminotransferase 34 units/L (0 to 34 units/L).

Correct Answer is A

Explanation

Choice A rationale

Platelets 60,000/mm³ is significantly below the normal range of 150,000 to 400,000/mm³, which can indicate a risk of bleeding and is a concern for a procedure like a liver biopsy.

Choice B rationale

Ammonia levels of 55 mcg/dL are within the normal range of 10 to 80 mcg/dL, so this value does not need to be reported.

Choice C rationale

Bilirubin 1.0 mg/dL is at the upper limit of the normal range of 0.3 to 1.0 mg/dL, but it does not necessarily indicate a significant risk for a liver biopsy.

Choice D rationale

Aspartate aminotransferase 34 units/L is at the upper limit of the normal range of 0 to 34 units/L, but it does not indicate a contraindication for the biopsy.
