After administering the client’s 0730 prescribed dose of regular insulin per a sliding scale, which action by the practical nurse (PN) has the highest priority?

Choice A reason: Taking a benzodiazepine with morphine is incorrect, as it increases sedation and respiratory depression risk, a dangerous opioid side effect. This indicates misunderstanding, as morphine’s primary management focuses on pain and side effects like constipation, not concurrent sedative use.

Choice B reason: Observing bowel movements and using a stool softener shows understanding, as morphine causes constipation by slowing gastrointestinal motility via opioid receptors. Proactive management with stool softeners prevents complications like impaction, aligning with safe opioid use in cancer pain management.

Choice C reason: Grapefruit juice avoidance is irrelevant to morphine, as it affects drugs metabolized by CYP3A4, not opioids. Morphine is metabolized via glucuronidation, unaffected by grapefruit. This indicates misunderstanding, as it does not address morphine’s key side effects or management.

Choice D reason: Watching for agitation or insomnia is not a primary concern with morphine, which causes sedation. These symptoms may relate to other conditions, but they do not reflect understanding of morphine’s effects, like constipation, making this choice incorrect.

Choice A reason: Palpitations may indicate electrolyte imbalances, like hypokalemia, a serious side effect of hydrochlorothiazide, a thiazide diuretic. It increases potassium excretion, disrupting cardiac electrical activity, potentially causing arrhythmias. Withholding the dose and notifying the provider is critical to prevent life-threatening cardiac complications, requiring urgent electrolyte assessment.

Choice B reason: Nervousness is a vague symptom not typically linked to hydrochlorothiazide’s side effects. It may reflect anxiety or other unrelated issues, not necessitating immediate drug cessation. Electrolyte imbalances or hypotension are more concerning, making this choice less urgent for withholding the medication.

Choice C reason: Nausea is a common, non-specific side effect of many medications, including hydrochlorothiazide, but is not severe enough to warrant withholding the dose. It may resolve or be managed symptomatically. More critical side effects, like electrolyte imbalances, take precedence, making this choice incorrect.

Choice D reason: Anorexia is not a primary concern with hydrochlorothiazide. While it may occur with diuretic-induced dehydration, it is less urgent than cardiac symptoms like palpitations. This symptom does not directly indicate a life-threatening side effect, so withholding the drug is not immediately necessary.
