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.
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 B reason: Arranging diet schedule around three regular meals a day is not a sufficient point for disease and symptom management for a client with type 2 diabetes mellitus. Diabetes mellitus is a condition that affects the body's ability to produce or use insulin, a hormone that regulates blood glucose levels. Eating three regular meals a day may not be enough to control blood glucose levels and prevent complications such as hypoglycemia or hyperglycemia. The nurse should teach the client to follow a balanced diet that includes carbohydrates, proteins, fats, vitamins, minerals, and fiber, and to eat smaller portions more frequently throughout the day.
Choice C reason: Using garlic, herbs, and spices will improve the flavor of food is not a specific point for disease and symptom management for a client with type 2 diabetes mellitus. Garlic, herbs, and spices are natural ingredients that can enhance the taste and aroma of food, but they do not have a direct impact on blood glucose levels or diabetes complications. The nurse should teach the client to limit the intake of salt, sugar, and saturated fats, and to choose foods that are low in glycemic index and high in antioxidants.
Choice D reason: Inspecting feet every month for ingrown nails, cuts, and calluses is not a frequent enough point for disease and symptom management for a client with type 2 diabetes mellitus. Diabetes mellitus can cause damage to the blood vessels and nerves in the feet, leading to reduced sensation, poor circulation, infection, ulceration, and amputation. The nurse should teach the client to inspect feet every day for any signs of injury or infection, and to wash, dry, moisturize, and protect them properly. The nurse should also advise the client to wear comfortable shoes and socks, avoid walking barefoot, and seek medical attention for any foot problems.
Correct Answer is ["B","C","D","E"]
Explanation
Choice A reason: This is incorrect because instructing the client and family to reconsider end of life choices is disrespectful and insensitive. The nurse should respect the client's autonomy and preferences and support their decisions.
Choice B reason: This is correct because teaching the client how to use guided imagery is a helpful intervention for coping with feelings related to death and dying. Guided imagery is a relaxation technique that involves visualizing positive images and scenarios that can reduce stress, anxiety, and pain.
Choice C reason: This is correct because recording the client's desire to live is an important intervention for coping with feelings related to death and dying. The nurse should acknowledge and validate the client's emotions and help them express their hopes and fears.
Choice D reason: This is correct because encouraging family to visit frequently is a beneficial intervention for coping with feelings related to death and dying. The nurse should facilitate family involvement and communication and help the client maintain meaningful relationships.
Choice E reason: This is correct because encouraging family to bring the client old photographs is a useful intervention for coping with feelings related to death and dying. The nurse should assist the client in reminiscing and reviewing their life story and achievements.
