A healthcare professional is reviewing the medical record of a client who has a new prescription for ceftriaxone. The healthcare professional should identify which of the following findings as a contraindication to this medication?

Correct Answer: C

Rationale: The correct answer is C: Penicillin allergy. Penicillin allergy is a contraindication for ceftriaxone because both medications are beta-lactam antibiotics. Seizure disorder (choice A), hypertension (choice B), and hyperlipidemia (choice D) are not contraindications for ceftriaxone and do not directly affect the use of this antibiotic.

Correct Answer: B

Rationale: The correct answer is to monitor the WBC count. Clozapine can cause agranulocytosis, a severe decrease in WBC count, which can increase the risk of infection. Monitoring the WBC count is essential to detect this potentially life-threatening condition early. Monitoring blood glucose levels (Choice A) is not directly related to clozapine use. Platelet count (Choice C) and hemoglobin levels (Choice D) are not typically affected by clozapine and are not the priority for monitoring in this case.

Correct Answer: A

Rationale: The correct action the nurse should take is to administer the medication over 60 minutes. This is important because administering vancomycin over 60 minutes helps prevent red man syndrome, a reaction that can occur with rapid infusion. Monitoring the client's blood glucose level (Choice B) is unrelated to vancomycin administration. Infusing the medication rapidly (Choice C) is incorrect and can lead to adverse reactions. Administering the medication using a filter needle (Choice D) is unnecessary for vancomycin administration.

Correct Answer: B

Rationale: Encouraging the use of an incentive spirometer is crucial for preventing respiratory complications postoperatively, such as atelectasis. Instructing the client to avoid deep breathing exercises (choice A) is incorrect as deep breathing exercises help prevent respiratory complications. Assisting with ambulation every 2 hours (choice C) is important for preventing other postoperative complications but not specifically respiratory ones. Applying sequential compression devices (SCDs) (choice D) is beneficial for preventing deep vein thrombosis but not directly related to respiratory complications.

Correct Answer: B

Rationale: The correct answer is B. Insulin glargine has a 24-hour duration of action, making it suitable for once-daily dosing for long-term blood sugar control. Choice A is incorrect as insulin glargine is a long-acting insulin with no pronounced peak effect in its action profile. Choice C is incorrect as insulin glargine is usually given at the same time each day regardless of meals. Choice D is incorrect as there is no specific requirement to avoid eating before or after taking insulin glargine.
