A nurse is caring for an infant who has heart failure and vomited following administration of digoxin. Which of the following actions should the nurse take?

A. Mixing digoxin with formula is not recommended, as it may affect the medication's absorption and effectiveness. It should be administered separately and as prescribed.
B. Giving an antiemetic may be considered if vomiting persists and is severe, but it is not the initial action. The nurse should first ensure the infant is stable and then administer the next dose of digoxin as prescribed.
C. Increasing fluid intake may help prevent dehydration if vomiting persists, but it does not address the administration of the next dose of digoxin.
D. Administering the next dose of digoxin as prescribed is appropriate, as long as the infant is stable and vomiting has ceased. The nurse should monitor for signs of toxicity and notify the healthcare provider if vomiting continues or if there are concerns about absorption.

A. Continuous monitoring of oxygen saturation is crucial in a vaso-occlusive crisis to detect any signs of hypoxia early, which could exacerbate the crisis and lead to more severe complications. This is important for assessing respiratory status, especially in patients with sickle cell disease who may be at risk for acute chest syndrome.

B. Oral intake should not be restricted during a vaso-occlusive crisis as hydration is important for maintaining adequate blood flow and preventing dehydration.

C. Hydroxyurea is used to reduce the frequency of painful crises in patients with sickle cell disease. It works by increasing the production of fetal hemoglobin, which can help prevent sickle cell crises.

D. Meperidine (Demerol) is an opioid analgesic commonly used to manage severe pain associated with sickle cell crises.

E. Vaccination is important in preventing infections, which can trigger or worsen a vaso-occlusive crisis in individuals with sickle cell disease. Ensuring the pneumococcal vaccine is current helps protect the adolescent from potential infections.

F. Placing the client on strict bed rest can increase the risk of thrombosis and impair circulation.

G. Folic acid supplementation is often recommended for patients with sickle cell disease to support red blood cell production and prevent folate deficiency, which can worsen anemia.

H. Cold compresses are not recommended as they can cause vasoconstriction, worsening the pain and sickling in vaso-occlusive crises. Warm compresses are generally preferred.
