Pediatric Respiratory Nursing Questions Questions
Question 1 of 5
During fetal circulation the pressure is greatest in the
Correct Answer: B
Rationale: Pressure in fetal circulation is greatest in the right atrium, allowing right-to-left shunting to bypass the lungs during intrauterine life. The pressure increases in the left atrium after birth. The liver does not filter blood during fetal life until the end. Blood bypasses the pulmonary vein during fetal life.
Question 2 of 5
Most newborns receive a prophylactic injection of vitamin K soon after birth. Which site is optimal for the newborn?
Correct Answer: D
Rationale: The correct answer is D because the vastus lateralis muscle is located away from important nerves and blood vessels, making it the optimal site for injections in newborns. Gluteal muscles are not recommended until a child has been walking for at least a year. The rectus femoris muscle is closer to nerves and blood vessels, posing a greater risk. The deltoid muscle is not recommended for newborn injections.
Question 3 of 5
The nurse is evaluating a newborn's circumcision 30 minutes after the procedure. The nurse notes excessive bleeding coming from the circumcised area. Which priority intervention should the nurse implement at this time?
Correct Answer: A
Rationale: Excessive bleeding after a circumcision is a serious concern as infants have a small total blood volume. Applying pressure to the site is the correct intervention to stop the bleeding. Continuing to observe could lead to additional blood loss. Tightening the diaper or applying petroleum jelly will not address the bleeding issue effectively.
Question 4 of 5
Which statement is true regarding growth and development during the first 6 months?
Correct Answer: B
Rationale: The statement that the infant will gain about 2 lb per month is true regarding growth and development during the first 6 months. This rate of weight gain is normal and expected for infants. The other statements are incorrect as infants typically grow more than 1 cm in length per month, regain birth weight within 14 days, and have a 2 cm increase in head circumference per month.
Question 5 of 5
During a prenatal education class regarding infant home care, the nurse is reviewing the simulated setting created by new mothers for putting the baby to bed. Which observation indicates to the nurse that the new mothers understood the nurse's teaching about infant safety?
Correct Answer: C
Rationale: The correct answer is C because infants should be positioned on their back for sleep to reduce the risk of sudden infant death syndrome (SIDS). Placing soft items like bumper pads, blankets, and stuffed animals in the crib can pose a suffocation hazard. The supine position is the safest sleeping position for infants, as indicated by the baby mannequin being in that position. The handmade quilt covering the baby mannequin is not safe and could increase the risk of SIDS.
