A nurse is caring for a hospitalized pre-operative client experiencing insomnia in the hospital at 3:00 am (0300).
Which nursing intervention is the most appropriate for this client?

An idiosyncratic drug effect is an unpredictable and uncommon reaction to a drug that is not related to the dose, the pharmacology, or the patient’s allergy or intolerance. It may be caused by genetic factors, metabolic abnormalities, or interactions with other drugs or substances. An example of an idiosyncratic drug effect is paradoxical agitation or excitement after receiving a sedative.

B. A toxic drug effect is a harmful reaction to a drug that is related to the dose or the pharmacology of the drug. It may cause symptoms such as nausea, vomiting, drowsiness, confusion, or respiratory depression. A toxic drug effect is unlikely to cause agitation after receiving a sedative unless there is an overdose or a drug interaction that increases the level of the sedative in the blood.

C. An allergic drug response is an immunological reaction to a drug that is not related to the dose or the pharmacology of the drug. It may cause symptoms such as rash, itching, swelling, fever, or anaphylaxis. An allergic drug response is unlikely to cause agitation after receiving a sedative unless there is a severe anaphylactic reaction that affects the brain or the circulation.

D. An unexpected drug interaction is a modification of the effect of one drug by another drug or substance that is not predictable based on their pharmacology. It may cause an increase or a decrease in the efficacy or toxicity of one or both drugs. An unexpected drug interaction may cause agitation after receiving a sedative if there is a synergistic effect that enhances the central nervous system stimulation of another drug or substance (such as caffeine, cocaine, or amphetamines) or if there is an antagonistic effect that reduces the central nervous system depression of the sedative (such as flumazenil, naloxone, or physostigmine). However, these interactions are usually known and avoidable by checking the patient’s history and medication list.

Collaborate with the prescriber about the order. This is because the nurse has a responsibility to ensure the safety and effectiveness of the medication administration and to question any orders that seem inappropriate or unclear. The nurse should not administer the medication as ordered without verifying it first, as this could cause harm to the client or result in a medication error. The nurse should not check to see if previous shift nurses gave the medication, as this does not address the issue of the current order and could lead to missed or duplicated doses. The nurse should not administer only the standard dose of the medication, as this could be against the prescriber’s intention and could compromise the client’s treatment or outcome.

Choice A is wrong because it does not follow the principle of safe medication administration and could put the client at risk of adverse effects or overdose.

Choice B is wrong because it does not respect the prescriber’s authority and could result in underdosing or ineffective therapy for the client.

Choice C is wrong because it does not solve the problem of the current order and could cause confusion or inconsistency in the medication administration.

Choice D is correct because it demonstrates critical thinking and professional accountability, and ensures that the order is appropriate and accurate for the client’s condition and needs.

The normal ranges for medication dosages depend on various factors, such as the type of medication, the route of administration, the client’s age, weight, renal function, liver function, and other comorbidities.

The nurse should always consult reliable sources of information, such as drug guides, pharmacists, or prescribers, to determine the safe and effective dosages for each client
