A mother calls the nurse to report that at 0900 she administered an oral dose of digoxin to her 4-month-old infant, but at 0920 the baby vomited the medicine. Which instruction should the nurse provide to this mother?

Administer a half dose now.

Give another dose.

Mix the next dose with food.

Withhold this dose.

Answer and Explanation

The Correct Answer is D

Choice A: Administering a half dose now is not advisable, because it may result in underdosing or overdosing of digoxin. Digoxin has a narrow therapeutic range and a high risk of toxicity, especially in infants and children. The amount of digoxin absorbed by the infant before vomiting is unknown, so giving a partial dose may not achieve therapeutic levels or may exceed safe levels.

Choice B: Giving another dose is not advisable, because it may result in overdosing of digoxin. Digoxin has a narrow therapeutic range and a high risk of toxicity, especially in infants and children. The amount of digoxin absorbed by the infant before vomiting is unknown, so giving a full dose may exceed safe levels and cause adverse effects such as nausea, vomiting, bradycardia, arrhythmias, or visual disturbances.

Choice C: Mixing the next dose with food is not advisable, because it may affect the absorption and bioavailability of digoxin. Digoxin should be taken on an empty stomach or at least one hour before or two hours after meals, because food can interfere with its absorption from the gastrointestinal tract and reduce its effectiveness.

Choice D: Withholding the dose is the safest option. If vomiting occurs within 30 minutes of administration, it’s generally advised to skip that dose to avoid the risk of overdose. The next dose should be given as scheduled Digoxin has a long half-life and accumulates in tissues, so missing one dose will not significantly affect its therapeutic effect. Withholding this dose will avoid overdosing and toxicity of digoxin, which can be life-threatening in infants and children. The nurse should also advise the mother to resume the regular dosing schedule and monitor the infant's pulse rate and signs of digoxin toxicity.

Correct Answer is A

Explanation

Choice A reason: This is correct because a firm mattress reduces the risk of suffocation and rebreathing of carbon dioxide, which are associated with SIDS.

Choice B reason: This is incorrect because propping the infant with a pillow can cause the infant to slide down and suffocate or obstruct the airway.

Choice C reason: This is incorrect because swaddling the infant in a blanket can cause overheating, which is a risk factor for SIDS.

Choice D reason: This is incorrect because placing the infant in a prone position can increase the risk of SIDS by impairing gas exchange and thermoregulation.

A. Center attention on positive upbeat music. B. Find outlets for more social interaction. C. Practice using muscle relaxation techniques. D. Think about reasons the episodes occur.

Correct Answer is C

Explanation

Choice A: Centering attention on positive upbeat music is not a specific instruction for the nurse to include, as this is a general coping strategy that may or may not be helpful for this client. This is a distractor choice.

Choice B: Finding outlets for more social interaction is not a relevant instruction for the nurse to include, as this may not address the underlying causes of anxiety or stress for this client. This is another distractor choice.

Choice C: Practicing using muscle relaxation techniques is an appropriate instruction for the nurse to include, as this can help reduce physical tension and promote calmness and relaxation for this client. Therefore, this is the correct choice.

Choice D: Thinking about reasons the episodes occur is not a helpful instruction for the nurse to include, as this can increase rumination and anxiety for this client. This is another distractor choice.
