A nurse is educating a patient prescribed a 10-day course of antibiotics for a bacterial infection.
Which statement by the patient indicates a need for further teaching regarding antibiotic therapy?

Step 1 is convert 1.5 cups of coffee to mL (1 cup = 240 mL): 1.5 × 240 mL = 360 mL.

Step 2 is convert 10 oz of water to mL (1 oz = 30 mL): 10 × 30 mL = 300 mL.

Step 3 is convert 8 oz of broth to mL (1 oz = 30 mL): 8 × 30 mL = 240 mL.

Step 4 is add all volumes: 360 mL + 300 mL + 240 mL + 750 mL = 1,650 mL. Final calculated answer is 1,650 mL..l

This question addresses the monitoring requirements for patients receiving potent opioid analgesics. It requires applying knowledge of opioid-induced respiratory depression, which is the most dangerous potential adverse effect, requiring constant vigilance to ensure patient safety and prevent hypoxic events during the postoperative recovery period.

Choice A rationale

While opioids can cause hypotension due to peripheral vasodilation, it is not as acutely life-threatening as respiratory depression. Blood pressure monitoring is important but secondary to the immediate, time-critical need to ensure the patient maintains a safe and effective rate of breathing.

Choice B rationale

Opioids do not typically cause direct changes to body temperature. While temperature monitoring is part of standard postoperative care to detect infection or other complications, it is not the primary vital sign concern when administering a dose of hydromorphone.

Choice C rationale

Hydromorphone is a powerful opioid that acts on central nervous system receptors to suppress the respiratory drive. Shallow respirations or a low respiratory rate are the most serious adverse effects, requiring immediate assessment to prevent respiratory arrest and significant patient harm.

Choice D rationale

Opioids can cause bradycardia, but this is generally managed effectively unless the patient is hemodynamically unstable. Heart rate is a vital parameter to monitor, but it is not the primary physiological concern following the administration of a potent opioid medication..
