A nurse is providing teaching to the caregiver of an infant who has a prescription for digoxin. Which of the following instructions should the nurse include?
"Digoxin may decrease your baby's heart rate."
"If your baby vomits a dose, do not repeat the dose to ensure that the correct amount is received."
"Give the correct dose of medication at regularly scheduled times."
"Do not offer your baby fluids after giving the medication."
The Correct Answer is C
Choice A reason: Digoxin is used to treat heart conditions by slowing the heart rate and increasing its efficiency. It does not increase the heart rate. The normal heart rate for a 12-month-old infant ranges from 80 to 160 beats per minute.
Choice B reason: If an infant vomits after taking digoxin, repeating the dose could lead to toxicity. Instead, caregivers should wait until the next scheduled dose or contact a healthcare provider for guidance.
Choice C reason: Administering digoxin at regular intervals ensures consistent therapeutic levels in the bloodstream, which is crucial for the medication's efficacy and safety.
Choice D reason: Offering fluids after medication does not interfere with digoxin's absorption. However, caregivers should be aware of the signs of digoxin toxicity, which include vomiting, lethargy, and bradycardia.

Choice C reason: A 22-25 gauge needle is recommended for intramuscular injections in toddlers to minimize discomfort and tissue damage.

Correct Answer is A
Explanation
Choice A reason: A sweat chloride content of 85 mEq/L is indicative of cystic fibrosis, as normal values are below 30 mEq/L, and values above 60 mEq/L are diagnostic for cystic fibrosis.
Choice B reason: Hard, packed stools could be a sign of cystic fibrosis but are not as diagnostic as a sweat chloride test.
Choice C reason: Increased blood levels of fat-soluble vitamins are not typically associated with cystic fibrosis; patients often have deficiencies due to malabsorption.
Choice D reason: A chest x-ray negative for atelectasis does not indicate cystic fibrosis, as atelectasis can be present in many conditions.
