A client with suspected appendicitis is waiting for surgery. What should the nurse do?

Choice A Reason
Urine negative for ketones is a normal finding and does not typically indicate an acute problem. Ketones in the urine can be a sign of uncontrolled diabetes or starvation, but their absence is expected in a well-nourished individual who is not in a state of diabetic ketoacidosis.

Choice B Reason
Sodium at 135 mg/dL and Potassium at 3.5 mEq/L are within normal ranges. The normal range for serum sodium is approximately 135-145 mEq/L, and for serum potassium, it is around 3.5-5.0 mEq/L. These values do not indicate an immediate concern for the patient with urosepsis.

Choice C Reason
A BUN of 34 mg/dL and Creatinine of 4.2 mg/dL are concerning. The normal range for BUN is approximately 6-20 mg/dL, and for Creatinine, it is about 0.6-1.2 mg/dL for males and 0.5-1.1 mg/dL for females. Elevated levels of BUN and Creatinine indicate impaired kidney function, which can be a complication of urosepsis and the nephrotoxic effects of gentamicin and vancomycin.

Choice D Reason
A white blood cell count of 12,000/mm³ is slightly elevated, which may be expected in a patient with an infection such as urosepsis. The normal range is approximately 4,500-11,000 WBCs/mm³. While this should be monitored, it does not require immediate reporting unless there is a significant change or it is outside the patient's baseline.

Choice A reason:
Administering an antiemetic is an important intervention in the PACU, especially if the patient is experiencing nausea or has a history of postoperative nausea and vomiting (PONV). However, it is not the first priority. Antiemetics work by blocking the neurotransmitters that trigger the vomiting reflex. Medications such as ondansetron or promethazine may be used.

Choice B reason:
Applying sequential compression devices is a preventive measure against deep vein thrombosis (DVT), which is a risk due to immobility after surgery. These devices help improve venous return from the lower limbs by applying intermittent pressure. While important, this intervention follows after the assessment of vital signs.

Choice C reason:
Assessing vital signs is the first and foremost priority when a patient is transferred to the PACU. Vital signs, including blood pressure, heart rate, respiratory rate, and oxygen saturation, provide immediate information about the patient's hemodynamic status and can indicate the need for urgent interventions. Any evidence of respiratory or circulatory compromise requires immediate attention.

Choice D reason:
Hanging the Lactated Ringers solution is part of managing the patient's fluid status postoperatively. Lactated Ringers is an isotonic solution that helps to replace lost fluids and maintain electrolyte balance. While important for patient care, it is not the initial priority upon arrival in the PACU.
