A nurse is collecting data from an infant a large patent ductus arteriosus. Which of the following is clinical manifestations should the nurse expect?
Machine like murmur
Chronic hypoxemia
Cyanosis with crying
Weak pulse
The Correct Answer is A
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.

Correct Answer is C
Explanation
A. Coloring book with crayons:
Coloring activities with crayons are typically more suitable for older children who have developed fine motor skills and hand-eye coordination. At 10 months old, infants are still in the early stages of motor development and may not have the dexterity to hold and manipulate crayons effectively. Additionally, infants at this age are more likely to put objects in their mouths, which poses a choking hazard with crayons.
B. Large-piece puzzles:
Puzzles with large pieces can be beneficial for older children's cognitive development by promoting problem-solving skills and hand-eye coordination. However, at 10 months old, infants are still developing their motor skills and may not have the ability to manipulate puzzle pieces effectively. Puzzles with small pieces can also pose a choking hazard for infants.
C. Crib gym:
A crib gym is a suitable toy for a 10-month-old infant as it provides opportunities for visual stimulation, reaching, grasping, and hand-eye coordination development. Crib gyms typically consist of hanging toys or objects that the infant can bat at or grasp while lying in their crib or playpen. This type of toy encourages exploration and interaction while ensuring safety within the confines of the crib.
D. Put-in take-out toy:
Put-in take-out toys involve placing objects into a container and then removing them, which can be engaging for infants. However, while this type of toy may provide some entertainment for a 10-month-old, it may not offer as much visual and tactile stimulation as a crib gym. Additionally, some put-in take-out toys may have smaller parts that pose a choking hazard for infants, so careful supervision is necessary.
Correct Answer is ["B","C"]
Explanation
A. "You should begin to manipulate the infant's bedtime based on the hospital's visiting hours."
This statement is incorrect. Manipulating the infant's bedtime based on hospital visiting hours may disrupt the infant's regular sleep schedule, potentially causing discomfort and distress. It's important to maintain the infant's routine as much as possible to promote comfort and well-being.
B. "You should bring the infant's favorite blanket to the hospital."
This statement is correct. Bringing the infant's favorite blanket or comfort item can provide familiarity and comfort during the hospital stay. Having familiar items from home can help soothe the infant and reduce anxiety associated with the new environment.
C. "You should read the child a story about hospitalization."
This statement is correct. Reading a story about hospitalization to the child can help prepare them for the upcoming experience and alleviate fear or anxiety. Choosing age-appropriate books that explain what to expect during a hospital stay can help normalize the experience and provide reassurance to the infant and parents.
D. "You will need to go home when it is not visiting hours."
This statement is incorrect. Parents are typically allowed to stay with their infant throughout the hospitalization, especially in the case of pediatric patients. Family presence is important for providing comfort and support to the infant and facilitating bonding during the hospital stay.
