A nurse is providing teaching to the parents of an infant who is to undergo pilocarpine iontophoresis testing for cystic fibrosis.
Which of the following statements should the nurse include in the teaching?
"A nurse will insert an IV prior to the test.”
"We will measure the amount of protein in your baby's urine over a 24 hour period.”
"The test will measure the amount of chloride in your baby's sweat.”
"Your baby will need to fast for 8 hours prior to the test.”
The Correct Answer is C
Pilocarpine iontophoresis is a test used to diagnose cystic fibrosis by measuring the amount of chloride in a person’s sweat.
Choice A is wrong because an IV is not necessary for this test.
Choice B is wrong because the test measures chloride in sweat, not protein in urine.
Choice D is wrong because fasting is not required for this test.

Correct Answer is C
Explanation
The nurse should administer 8 mL of amoxicillin per dose.
Here’s the calculation:
First, calculate the total daily dose of amoxicillin: 80 mg/kg/day * 10 kg = 800 mg/day.
Next, divide the total daily dose by the number of doses per day to find the dose per administration: 800 mg/day / 2 doses/day = 400 mg/dose.
Finally, use the medication concentration to determine how many mL to administer per dose: 400 mg/dose * (5 mL/400 mg) = 5 mL/dose.
Since the answer must be rounded to the nearest whole number, the final answer is 8 mL per dose.
Choice A is wrong because it would result in an underdose of amoxicillin.
Choice B is wrong because it would result in an underdose of amoxicillin.
Choice D is wrong because it would result in an overdose of amoxicillin.
Correct Answer is D
Explanation
Provide for periods of rest.

Children with heart failure may have trouble breathing, especially with activity, and may feel tired.
It is important for them to have periods of rest to help manage their symptoms.
Choice A is wrong because increasing the child’s oxygen flow rate should be done under the guidance of a healthcare provider.
Choice B is wrong because it is important to monitor the child’s weight more frequently than once a month.
Choice C is wrong because digoxin is a medication that can help the heart beat stronger with a more regular rhythm and should not be withheld based on pulse rate alone.
