A nurse is preparing to administer a medication to a patient. Which of the following routes of administration would result in the fastest rate of absorption?
Oral tablet
Intramuscular injection
Intravenous injection
Subcutaneous injection
The Correct Answer is C
A. Oral tablet: Oral medications must pass through the gastrointestinal tract and undergo first-pass metabolism in the liver before entering systemic circulation, significantly delaying the onset of action compared to parenteral routes.
B. Intramuscular injection: IM injections are absorbed faster than oral or subcutaneous routes due to the rich blood supply in muscle tissue. The rate of absorption depends on factors such as blood flow to the muscle, the solubility of the drug, and the injection site. While faster than oral administration, it is still slower than IV.
C. Intravenous injection: IV administration delivers the drug directly into the bloodstream, resulting in immediate systemic availability and the fastest onset of action. This route bypasses absorption barriers entirely.
D. Subcutaneous injection: SC injections are absorbed more slowly than IM and IV routes because of the lower vascularity of subcutaneous tissue. Onset of action is delayed relative to other parenteral methods.

Correct Answer is D
Explanation
A. Advise the parent to discontinue the medication immediately: Discontinuing the medication without consulting the healthcare provider is unsafe. Stimulants are effective in managing ADHD symptoms, and any adjustments should be made under medical supervision. Abrupt cessation may lead to a return or worsening of symptoms.
B. Encourage the parent to eliminate all snacks between meals to promote hunger at mealtimes: While reducing snacks may improve appetite, it can also result in missed opportunities for nutrient intake, especially when the child already has a reduced appetite due to the medication. This intervention is not the most appropriate or immediate.
C. Encourage the parent to increase the child's physical activity to stimulate appetite: Physical activity can naturally increase appetite over time, but it is not the most direct or effective strategy for managing stimulant-induced appetite suppression. This approach is more of a long-term supportive strategy.
D. Encourage the parent to make breakfast the most important meal of the day before administering the medication: Stimulant medications commonly reduce appetite, especially later in the day. Ensuring the child eats a nutritious breakfast before taking the medication helps maximize calorie and nutrient intake when appetite is highest. This is the most appropriate initial nursing intervention.
Correct Answer is ["30"]
Explanation
Given quantity = 6 teaspoons
Desired unit = mL (milliliters)
Convert from teaspoons to milliliters
1 teaspoon ≈ 5 mL
6 teaspoons × 5 mL/teaspoon
= 30 mL
