A nurse is collecting data from a client who received levalbuterol 30 min ago.
Which of the following findings should the nurse identify as a therapeutic effect of the medication?
Wheezing decreases.
Respiratory rate increases.
Nausea decreases.
Heart rate increases.
The Correct Answer is A
Choice A rationale:
Levalbuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Therefore, a decrease in wheezing is a therapeutic effect of the medication, making this the correct choice.
Choice B rationale:
While levalbuterol can cause an increase in respiratory rate as a side effect, it is not considered a therapeutic effect of the medication. The primary goal of levalbuterol is to improve breathing by relaxing the muscles of the airways, not to increase respiratory rate.
Choice C rationale:
Levalbuterol does not directly affect nausea. It is primarily used to treat conditions related to breathing such as asthma and chronic obstructive pulmonary disease.
Choice D rationale:
An increased heart rate is a potential side effect of levalbuterol, not a therapeutic effect.

Correct Answer is A
Explanation
Choice A rationale:
Renal excretion time slows for medication. As people age, kidney function gradually decreases, which slows the excretion of medications. This can lead to increased levels of the drug in the body, which can increase the risk of side effects.
Choice B rationale:
Hepatic enzymes do not process medications more rapidly in older adults. In fact, liver function also decreases with age, which can slow the metabolism of medications.
Choice C rationale:
Brain receptors do not become less sensitive to medications in older adults. The sensitivity of brain receptors to medications can vary widely and is not necessarily related to age.
Choice D rationale:
Gastric emptying rate does not increase with age. On the contrary, it often slows down, which can affect the absorption of some medications.
Correct Answer is ["1"]
Explanation
Step 1: Convert the child's weight from pounds to kilograms.
44 pounds / 2.2 pounds/kg = 20 kg
Step 2: Calculate the child's total daily dose of gentamicin.
20 kg * 6 mg/kg/day = 120 mg/day
Step 3: Divide the child's total daily dose of gentamicin by the number of doses per day.
120 mg / 3 doses/day = 40 mg/dose
Step 4: Calculate the volume of gentamicin to be administered with each dose.
40 mg / 40 mg/mL = 1 mL/dose
Step 5: Round the answer to the nearest whole number and add a leading zero if necessary.
1 mL/dose = 1 mL/dose
Answer: 1 mL with each dose.
