Question 1 of 5
Which is the most critical physiologic change required of the newborn?
Correct Answer: D
Rationale: The most critical physiologic change required of the newborn is the onset of breathing. Prior to birth, the fetus receives oxygen from the mother's blood through the placenta. However, once the newborn is delivered, it needs to begin breathing on its own to support oxygen exchange and remove carbon dioxide from the body. The respiratory system must transition from a fluid-filled state in the womb to an air-filled state outside the womb. The onset of breathing is essential for the newborn's survival and initiates the process of oxygenation of tissues and removal of carbon dioxide, which are vital for metabolism and overall physiological functioning. While closure of fetal shunts, stabilization of fluid and electrolytes, and body-temperature maintenance are also important changes that occur in the newborn, the onset of breathing is the most critical to ensure proper oxygenation of the body's tissues.
Question 2 of 5
A nurse is conducting discharge teaching for parents of a newborn. The nurse instructs the parents on which method of care for the umbilical cord? (Select all that apply.)
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
The nurse is talking to the parents of a child with pediculosis capitis. Which should the nurse include when explaining how to manage pediculosis capitis?
Correct Answer: D
Rationale: The nurse should include in the explanation that in managing pediculosis capitis, it is necessary to remove nits with an extra-fine-tooth comb or tweezers since nits are attached to the hair shaft and can be difficult to wash out with regular shampoo. Removing the nits is crucial to prevent reinfestation, as they can hatch and start the cycle again. Cutting the hair shorter is not necessary unless the infestation is severe. It is important to distinguish viable (live) nits from nonviable (dead) ones and remove only the viable ones as the nonviable ones do not pose a threat of reinfestation.
Question 4 of 5
Recent studies indicate that a deficiency of which vitamin correlates with increased morbidity and mortality in children with measles?
Correct Answer: A
Rationale: Recent studies have shown that a deficiency of vitamin A correlates with increased morbidity and mortality in children with measles. Vitamin A plays a crucial role in supporting the immune system and helps protect against severe complications of measles, such as pneumonia and vision problems. Children with measles are at higher risk of vitamin A deficiency due to factors such as decreased intake and increased utilization of vitamin A during infection. Providing vitamin A supplementation to children with measles has been shown to reduce the severity of the disease and improve outcomes. Therefore, ensuring adequate vitamin A levels is essential in the management of children with measles to reduce morbidity and mortality.
Question 5 of 5
An infant experienced an apparent life-threatening event (ALTE) and is being placed on home apnea monitoring. Parents have understood the instructions for use of a home apnea monitor when they state?
Correct Answer: C
Rationale: The correct statement indicating understanding of the instructions for use of a home apnea monitor is "We will check the monitor several times a day to be sure the alarm is working." This is important because regular monitoring of the device's functioning ensures that it is able to detect any potential apnea episodes or abnormalities in the infant's breathing patterns. Checking the monitor several times a day helps in maintaining the safety and effectiveness of the monitor in alerting the parents to any potential issues with the infant's breathing. The other options are incorrect: A is incorrect because adjusting the monitor to eliminate false alarms can compromise its accuracy, B is incorrect as the infant should sleep in a separate safe sleep environment to reduce the risk of SIDS, and D is incorrect as the monitor should be placed near the infant's crib but not directly in it for safety reasons.
