A nurse is caring for a 45-year-old male client in a medical-surgical unit who has a new prescription for cefazolin.
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
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 A
Explanation
Choice A rationale
A changed mental status is a common sign of a urinary tract infection, especially in older adults, due to the effects of the infection on the central nervous system.
Choice B rationale
WBC count 9,000/mm³ is within the normal range of 5,000 to 10,000/mm³ and does not indicate an infection on its own.
Choice C rationale
Diminished reflexes are not typically associated with bladder infections and are not a reliable indicator.
Choice D rationale
A temperature of 37.3°C (99.1°F) is within the normal range and does not necessarily indicate a bladder infection.
Correct Answer is B
Explanation
Choice A rationale
Peritonitis usually leads to increased respiratory rate rather than decreased respirations due to abdominal pain and possible sepsis. Rapid breathing is a common symptom as the body tries to compensate for the infection and discomfort.
Choice B rationale
Absent bowel sounds are a hallmark sign of peritonitis, indicating a lack of intestinal activity due to severe inflammation of the peritoneum. This condition can lead to ileus, where the intestines stop functioning properly.
Choice C rationale
Peripheral edema is not typically associated with peritonitis. Peritonitis primarily affects the abdomen and does not commonly cause fluid accumulation in the extremities. Edema is more related to conditions affecting the heart, liver, or kidneys.
Choice D rationale
Polyuria, or excessive urination, is not a symptom of peritonitis. Peritonitis primarily affects the abdominal cavity and symptoms include severe abdominal pain, fever, and a rigid abdomen. Polyuria is often associated with conditions like diabetes.
