The nurse explained how to position an infant with tetralogy of Fallot if the infant suddenly becomes cyanotic. Which statement by the father leads the nurse to determine he understood the instructions?
"If the baby turns blue, I will immediately put the baby upright in an infant seat."
"If the baby turns blue, I will lay him down on a firm surface with his head lower than the rest of his body."
"If the baby turns blue, I will put the baby in supine position with his head elevated."
"If the baby turns blue, I will hold him against my shoulder with his knees bent up toward his chest."
The Correct Answer is D
This position, often referred to as the "knee-to-chest" position, is recommended during a cyanotic spell in infants with tetralogy of Fallot because it can help increase venous return to the heart and improve oxygenation. It's important for caregivers to understand this positioning as part of the management for hypercyanotic spells in children with this condition.
A. Placing the baby upright in an infant seat may help improve blood flow and oxygenation, but it's not the recommended position for managing cyanosis in a baby with tetralogy of Fallot.
B. Placing the baby with the head lower than the rest of the body could potentially worsen cyanosis by increasing right-to-left shunting of blood and decreasing pulmonary blood flow.
C. Placing the baby in a supine position with the head elevated worsens pulmonary blood flow by increasing systemic vascular resistance. This position can help worsen cyanosis by promoting better oxygenation.

Correct Answer is B
Explanation
B. The most serious complication associated with skeletal traction is osteomyelitis, an infection that involves the bone. This condition can occur when organisms gain access to the bone either systemically or through the openings created by the metal pins or wires used in the traction.
A. Increased blood pressure can occur for various reasons but it is not the most serious complication associated with skeletal traction.
C. A decrease in urine output could indicate systemic infection which is a late feature of osteomyelitis and therefore, not the earliest to monitor.
D. Changes in appetite can occur in response to pain or stress but they are not typically the most serious complication associated with skeletal traction.
Correct Answer is D
Explanation
D. This is the correct characteristic of decerebrate posturing. Decerebrate posturing is characterized by rigid extension and pronation (turning inward) of the arms and legs. It indicates severe neurological dysfunction and increased intracranial pressure, often involving damage to the brainstem.
A. This characteristic is not associated with decerebrate posturing. Adduction refers to movement toward the midline of the body, which is not typically observed in decerebrate posturing.
B. This description is not characteristic of decerebrate posturing. Decerebrate posturing involves extension, not flexion, of the upper extremities, along with extension and pronation (not adduction) of the lower extremities.
C. Flaccid paralysis refers to the absence of muscle tone and movement, which is not characteristic of decerebrate posturing. Decerebrate posturing involves increased muscle tone and abnormal, rigid extension of the arms and legs.
