Which principle of pharmacokinetics must the nurse keep in mind when administering medication to an infant?.
Metabolism of drug by the kidneys is slower, so reduced dosage is needed.
Absorption of oral medications is more predictable but more rapid than in adults.
There's an increased risk of toxicity with use of topical agents.
Protein binding of drugs is greater than in adults.
The Correct Answer is C
Choice A rationale:
While it’s true that infants have slower drug metabolism, this is generally due to liver immaturity, not kidney function.
Choice B rationale:
Absorption of oral medications in infants can be unpredictable due to their immature digestive systems.
Choice C rationale:
Infants do have an increased risk of toxicity with the use of topical agents because their skin is thinner and more permeable.
Choice D rationale:
Protein binding of drugs is actually less in infants than in adults, not greater.

Correct Answer is ["83"]
Explanation
Step 1 is to identify the given values: Volume (V) = 250 mL Time (T) = 30 min Drop factor © = 10 gtt/mL
Step 2 is to substitute these values into the formula for calculating the manual IV flow rate: Flow Rate ® = (V ÷ T) × C
Step 3 is to perform the calculation: R = (250 mL ÷ 30 min) × 10 gtt/mL R = 83.33 gtt/min
Since we need to round off to the nearest whole number, the flow rate is 83 gtt/min.
Correct Answer is A
Explanation
Choice A rationale:
This statement is measurable because it provides a specific timeframe (2 weeks after initial training) for the patient to be able to self-administer insulin injections.
Choice B rationale:
This statement is about the nurse’s actions, not a goal for the patient.
Choice C rationale:
While understanding how insulin works in the body is important, this statement is not measurable.
Choice D rationale:
Understanding a diabetic diet is important for a patient taking insulin, but this statement does not provide a measurable goal.
