A patient undergoing radiation treatment for laryngeal cancer has developed xerostomia and mucositis, leading to an imbalance in nutritional intake.
What is the most likely reason for this issue?

The correct answer is A. The nurse should first implement the prescription of Cefazolin 1 gram intravenously every 6 hours.

This is because, on admission of a patient to the postanesthesia care unit (PACU) from surgery, the first priority is to assess the airway and breathing status. Administering Cefazolin, an antibiotic, helps prevent postoperative infections, which is crucial in the immediate postoperative period.

Choice A rationale

Noting the presence of an auscultatory gap, which is a period of abnormal silence in Korotkoff sounds during blood pressure measurement, is important. However, in this case, the silence followed by a Korotkoff sound is a normal finding and does not indicate an auscultatory gap.

Choice B rationale

After inflating a blood pressure cuff and releasing the valve, the nurse hears silence followed by a Korotkoff sound. This is a normal finding and indicates that the nurse should continue with the blood pressure assessment.

Choice C rationale

Re-inflating the cuff to a higher number is not necessary in this case as the initial silence followed by a Korotkoff sound is a normal finding.

Choice D rationale

Repositioning the stethoscope over the brachial artery may not resolve the issue of hearing silence followed by a Korotkoff sound. It is important to assess the situation further before making adjustments.
