A nurse is caring for a child who is postoperative following surgical correction of Tetralogy of Fallot. Which of the following findings should the nurse identify as an indication of heart failure?
Weight loss
Decreased respirations
Exercise intolerance
Bradycardia
The Correct Answer is C
Choice A reason: Weight loss is not typically an indication of heart failure. In fact, patients with heart failure may experience weight gain due to fluid retention.
Choice B reason: Decreased respirations are not a common sign of heart failure. Instead, heart failure can cause increased respiratory rate and effort due to fluid accumulation in the lungs.
Choice C reason: Exercise intolerance, or difficulty in engaging in physical activity, is a classic symptom of heart failure. It occurs due to the heart's inability to pump enough blood to meet the body's demands during exercise.
Choice D reason: Bradycardia, or a slower than normal heart rate, is not a direct indication of heart failure. While it can be associated with certain cardiac conditions, it is not a specific sign of heart failure.

Correct Answer is D
Explanation
Choice Areason: An upper respiratory infection 2 days ago, if the child is currently well, is not a contraindication for the MMR vaccine. Vaccines can be given to children with a minor illness.
Choice Breason: A temperature of 37.2° C (99°F) is a mild elevation and is not a contraindication for receiving the MMR vaccine. Vaccination can proceed if the child is only mildly ill.
Choice C reason: A family history of seizures is not a contraindication for the MMR vaccine. While there is a small risk of febrile seizures, the benefits of vaccination outweigh the risks.
Choice D reason: An allergy to neomycin is a contraindication for the MMR vaccine because neomycin is used in the vaccine production process. Children with a known severe allergic reaction to neomycin should not receive the vaccine.
Correct Answer is B
Explanation
Choice A reason: Applying tepid water to the old dressings can help with their removal and may reduce discomfort, but it does not address the greatest risk to the client, which is infection.
Choice B reason: Checking the wound sites for manifestations of infection is crucial as burn injuries compromise the skin's protective barrier, making the client highly susceptible to infections. Infections can lead to further complications and delay healing.
Choice C reason: Performing passive range-of-motion exercises is important for maintaining joint mobility and preventing contractures in burn patients, but it is not the primary intervention for addressing the greatest risk of infection.
Choice D reason: Adjusting the room temperature to 33°C (91.4°F) can create a more comfortable environment for the burn patient and prevent hypothermia, but it is not directly related to the prevention of infection, which is the greatest risk.
