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
Placing the patch in the same location repeatedly can lead to skin irritation, reduced absorption due to stratum corneum thickening, and localized adverse reactions. Rotation of application sites allows the skin to recover, maintains optimal drug absorption, and prevents cumulative dermal irritation.
Choice B rationale
Transdermal patches often contain significant amounts of medication, including controlled substances or potent drugs. Discarding them in the trash can poses risks of accidental exposure to others, environmental contamination, and diversion. Proper disposal protocols, such as flushing or returning to pharmacy, are crucial.
Choice C rationale
While transdermal patches are designed for systemic absorption, specific sites are recommended to optimize efficacy and minimize adverse effects. Areas with less hair, intact skin, and good circulation are preferred. Improper placement can lead to erratic absorption or local irritation, reducing therapeutic benefit.
Choice D rationale
The nurse should always wear gloves when handling transdermal patches to prevent direct skin contact with the medication. Many transdermal drugs can be absorbed through the nurse's skin, leading to unintended pharmacological effects or sensitization. Gloves provide a crucial barrier against dermal absorption.
Correct Answer is ["147.9"]
Explanation
Step 1: Convert fluid ounces to milliliters. 1 fl. oz = 29.5735 mL.
Step 2: Multiply the given fluid ounces by the conversion factor. 5 fl. oz × 29.5735 mL/fl. oz = 147.8675 mL.
Step 3: Round the answer to the nearest tenth. 147.9 mL.
