A nurse is contributing to the plan of care for a 2-month-old infant who has just undergone cleft palate repair. The nurse should contribute which of the following interventions to the client's plan of care?

A. Machine-like murmur.

This option is correct. A characteristic clinical manifestation of a large patent ductus arteriosus is a continuous "machine-like" murmur heard on auscultation. This murmur is typically heard best at the upper left sternal border and may radiate to the back.

B. Chronic hypoxemia.

Chronic hypoxemia is not typically a primary manifestation of a large PDA. While PDA can lead to increased pulmonary blood flow and potentially contribute to pulmonary congestion, chronic hypoxemia may not be a prominent feature unless complications such as heart failure develop.

C. Cyanosis with crying.

Cyanosis with crying is more commonly associated with cyanotic congenital heart defects such as tetralogy of Fallot. While PDA can contribute to cyanosis in certain circumstances, it is not typically a consistent clinical manifestation.

D. Weak pulse.

A weak pulse is not typically associated specifically with a large PDA. Infants with PDA may have bounding pulses due to increased blood flow through the ductus arteriosus.

A. Restrain the toddler for 1 hr after the procedure:

This choice involves restraining the toddler for a period of time after the lumbar puncture procedure. However, restraining a toddler for such a prolonged period is not typically necessary and may cause distress and discomfort to the child. Moreover, prolonged restraint is not recommended as it can hinder the child's mobility and may lead to emotional distress.

B. Swaddle the toddler in a warm blanket:

Swaddling a toddler in a warm blanket may provide comfort, but it is not directly relevant to the lumbar puncture procedure itself. While comfort measures are important for overall patient care, they should not replace or interfere with the specific positioning requirements for medical procedures like a lumbar puncture.

C. Ask another nurse to assist with holding the toddler in a prone position:

This choice involves having another nurse assist in holding the toddler in a prone (face-down) position during the lumbar puncture procedure. However, the prone position is not typically used for lumbar punctures in toddlers. Placing the toddler in a prone position might make the procedure more challenging and less safe for both the child and the healthcare provider.

D. Place the toddler in a side-lying knee-chest position:

Placing the toddler in a side-lying knee-chest position is the correct action for a lumbar puncture procedure in a toddler. This position maximizes the space between the vertebrae, making it easier for the healthcare provider to access the lumbar area safely and accurately. It also helps minimize the risk of injury and discomfort for the toddler during the procedure. Therefore, this choice is the most appropriate for ensuring the success and safety of the lumbar puncture procedure.
