The patient is to receive oral guaifenesin (Mucinex) twice a day.
Today, the nurse was busy and gave the medication 2 hours after the scheduled dose was due.
What type of problem does this represent?
"Right medication".
"Right route".
"Right time".
"Right dose".
The Correct Answer is C
Choice A rationale
"Right medication" refers to ensuring that the drug administered is precisely the one prescribed by the healthcare provider. This involves verifying the medication name, strength, and formulation against the order. In this scenario, the issue is not the medication itself, but rather the timing of its administration, making this choice incorrect.
Choice B rationale
"Right route" pertains to administering the medication via the prescribed pathway (e.g., oral, intravenous, subcutaneous). This ensures that the drug reaches the systemic circulation or target site effectively. The scenario explicitly states "oral guaifenesin," indicating the route was correct; the error lies in the timing.
Choice C rationale
"Right time" is a crucial aspect of medication administration, ensuring that the drug is given at the prescribed frequency and within the specified time window. Administering a medication 2 hours after its scheduled dose constitutes a deviation from the ordered time, potentially affecting its therapeutic efficacy or peak plasma concentration.
Choice D rationale
"Right dose" involves verifying that the amount of medication given is precisely what was ordered, preventing under-dosing or over-dosing. The scenario does not indicate any error in the quantity of guaifenesin administered, only the timing of its delivery. Therefore, this choice is not applicable to the described problem.

Correct Answer is D
Explanation
Choice A rationale
Asking the patient to turn their head side-to-side against resistance assesses the accessory nerve (cranial nerve XI), which innervates the sternocleidomastoid and trapezius muscles. This action tests muscle strength and integrity of the nerve pathways responsible for head and shoulder movement.
Choice B rationale
Asking the patient to stick out the tongue and move it side-to-side from midline assesses the hypoglossal nerve (cranial nerve XII). This nerve is responsible for the motor control of the intrinsic and extrinsic muscles of the tongue, crucial for speech articulation and swallowing.
Choice C rationale
Asking the patient to read the smallest set of letters on a Snellen eye chart assesses visual acuity, primarily testing the optic nerve (cranial nerve II) and the visual pathways. This evaluates the patient's ability to discern details at a distance.
Choice D rationale
Asking the patient to identify the smell of vanilla and orange peel directly assesses the olfactory nerve (cranial nerve I). This nerve is responsible for the sense of smell, and presenting distinct, non-irritating odors allows for the evaluation of its function and patency.
Correct Answer is ["25"]
Explanation
Step 1 is to determine the total infusion time in minutes. 1 L = 1000 mL. 1000 mL ÷ (150 mL/h) = 6.666. hours. 6.666. hours × (60 min/hour) = 400 minutes.
Step 2 is to calculate the flow rate in drops per minute. (1000 mL ÷ 400 min) × (10 gtts/mL) = 25 gtts/min. The flow rate is 25 gtts/min.
