A nurse is collecting data from an infant who has a large patent ductus arteriosus. Which of the following is clinical manifestations should the nurse expect?
Cyanosis with crying
Weak pulses
Chronic hypoxemia
Machine-like murmur
The Correct Answer is D
A. Cyanosis with crying: Cyanosis is less common in isolated PDA and more indicative of other congenital heart defects. PDA usually results in increased pulmonary blood flow and may not directly cause cyanosis, especially in less severe cases.
B. Weak pulses: PDA typically causes increased pulmonary blood flow and can result in bounding pulses rather than weak ones. Weak pulses are more indicative of reduced cardiac output, which is not characteristic of PDA.
C. Chronic hypoxemia: Chronic hypoxemia is less associated with PDA and more common in cyanotic heart defects where oxygenated and deoxygenated blood mix. PDA primarily affects the volume of blood flow to the lungs and may not lead to hypoxemia unless complicated by other conditions.
D. Machine-like murmur: A characteristic feature of PDA is a continuous, machine-like murmur caused by turbulent blood flow between the aorta and the pulmonary artery. This murmur is a hallmark sign of PDA and is typically heard during auscultation.

Correct Answer is A
Explanation
A. "You should bring the infant's favourite blanket to the hospital." Bringing the infant's favourite blanket can provide comfort and a sense of security in an unfamiliar hospital environment. It helps the child feel more at ease and can reduce anxiety and stress associated with hospitalization.
B. "You should begin to manipulate the infant's bedtime based on the hospital’s visiting hours." Disrupting the infant’s usual sleep routine can lead to increased stress and irritability. It is better to maintain familiar routines as much as possible to provide comfort and stability during the hospital stay.
C. "You should read the child a story about hospitalization." At 8 months, an infant may not comprehend stories about hospitalization. Reading stories is more effective for older children who can understand and process the information. The focus for infants should be on comfort and familiarity.
D. "You will need to go home when it is not visiting hours." Parents are typically encouraged to stay with their young children in the hospital whenever possible. Parental presence is crucial for the infant’s emotional well-being and can help reduce anxiety.
Correct Answer is B
Explanation
A. Capillary refill less than 2 seconds: A capillary refill time of less than 2 seconds indicates good peripheral circulation, which is normal and not a cause for concern in this context. It is not the priority.
B. Tingling in the right foot Rationale: Tingling (paraesthesia) can be a sign of nerve damage or compromised circulation, which may indicate complications such as compartment syndrome. This is a priority finding because it can lead to severe consequences if not addressed promptly.
C. 2+ right pedal pulse Rationale: A 2+ pedal pulse indicates a normal pulse strength, which suggests that there is adequate blood flow to the extremity. It is not a priority compared to the potential for neurological or circulatory compromise.
D. Respiratory rate 24/min Rationale: A respiratory rate of 24/min is within the normal range for a school-age child (18-30 breaths per minute). While it is important to monitor vital signs, it is not a priority concern related to the fracture.
