A nurse is assisting with the care of an infant who has heart failure. Which of the following actions should the nurse take?

Choice A rationale:
Edema. Edema, the accumulation of fluid in the tissues, is not the primary indicator of compartment syndrome. While edema can occur due to various reasons, it's not specific to compartment syndrome. Compartment syndrome primarily involves increased pressure within a closed space (muscle compartment), which can compromise blood circulation and nerve function.
Choice B rationale:
Mottling. Mottling refers to a patchy, bluish discoloration of the skin that occurs due to poor blood circulation and is often seen in critically ill patients. While it might indicate circulatory issues, it's not a direct sign of compartment syndrome. Compartment syndrome is more closely associated with symptoms such as severe pain, numbness, and decreased or absent pulses.
Choice C rationale:
Urticaria. Urticaria, also known as hives, is a skin rash characterized by raised, itchy, and red or white welts. It is typically caused by an allergic reaction or other factors such as medications. Urticaria is unrelated to compartment syndrome, which involves the compression of nerves and blood vessels within a closed anatomical compartment, leading to ischemia and potential tissue damage.
Choice D rationale:
Pulselessness. Pulselessness is a critical sign that the nurse should monitor when conducting a circulatory check for compartment syndrome. Compartment syndrome occurs when there is increased pressure within a confined space (muscle compartment), leading to compromised blood flow and oxygen delivery to the tissues. The lack of a palpable pulse in the affected area suggests that blood flow is severely compromised. This is a late sign of compartment syndrome and requires immediate intervention to prevent tissue necrosis and long-term complications.

Choice A rationale:
Ensuring the infant bottle feeds for 45 minutes is not recommended for an infant with heart failure. Prolonged feeding sessions can lead to increased fatigue and stress on the infant's cardiovascular system, exacerbating the heart failure symptoms.
Choice B rationale:
Administering digoxin for a pulse of 70/min is not appropriate. Digoxin is commonly used in heart failure cases to improve cardiac contractility and reduce heart rate. However, giving digoxin solely based on the heart rate without considering other factors can lead to potential overdose and adverse effects.
Choice C rationale:
(Correct Choice) Allowing for frequent rest periods is crucial in the plan of care for an infant with heart failure. Infants with heart failure often experience fatigue and difficulty feeding due to compromised cardiac function. Allowing them to rest between activities helps conserve energy and supports their overall well-being.
Choice D rationale:
Maintaining the infant in a supine position is not the best choice for an infant with heart failure. While the supine position is recommended for safe sleep to reduce the risk of sudden infant death syndrome (SIDS), it may not be optimal for an infant with heart failure. An inclined position may be more suitable to alleviate potential respiratory distress.
