A nurse is providing vehicle safety education to the parents of a premature newborn.
Which of the following statements should the nurse include in the teaching?

"Your newborn will need to have a car seat test prior to discharge.”.

"Position the retainer clip at the level of your newborn's abdomen.”.

"Place your newborn in a front-facing car seat in the back seat of the vehicle.”.

"You should secure your newborn's car seat at a 60-degree angle.”.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Premature newborns have immature respiratory and neurological systems, making them vulnerable to respiratory compromise and apnea in a car seat. A car seat test prior to discharge assesses their ability to maintain adequate oxygenation and heart rate while positioned in the car seat for a prolonged period, ensuring safety.

Choice B rationale

The retainer clip should be positioned at the level of the newborn's armpits, not the abdomen. Proper placement at the armpit level ensures that the harness straps are snug over the shoulders and chest, effectively restraining the infant and preventing ejection in the event of a collision, optimizing crash protection.

Choice C rationale

Newborns, especially premature ones, must always be placed in a rear-facing car seat in the back seat of the vehicle. Rear-facing provides optimal support for the newborn's fragile head, neck, and spine, distributing crash forces over the entire back and significantly reducing the risk of severe injuries in a collision.

Choice D rationale

The recommended angle for a rear-facing car seat is typically between 30 to 45 degrees, depending on the specific car seat model, not 60 degrees. This recline angle is crucial to prevent the newborn's head from falling forward and compromising their airway, which is particularly critical for a premature infant with underdeveloped neck control. .

Correct Answer is C

Explanation

Step 1 is to determine the number of days from April 1 to December 26. Days in April = 30 - 1 + 1 = 30 days. Days in May = 31 days. Days in June = 30 days. Days in July = 31 days. Days in August = 31 days. Days in September = 30 days. Days in October = 31 days. Days in November = 30 days. Days in December = 26 days. Total number of days = 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 26 = 270 days.

Step 2 is to convert the total number of days into weeks. 270 days ÷ 7 days/week = 38.57 weeks.

Step 3 is to round to the nearest whole week. The anticipated gestational age is 39 weeks.

A. Temperature instability. B. Acrocyanosis. C. Jitteriness. D. Hypotonia. E. Abdominal distention.

Correct Answer is ["A","C","D"]

Explanation

Choice A rationale

Temperature instability, particularly hypothermia, is a significant indicator of neonatal hypoglycemia. Glucose is the primary metabolic fuel for thermogenesis, and its deficiency impairs the infant's ability to maintain core body temperature. The normal newborn temperature range is typically 36.5°C to 37.5°C (97.7°F to 99.5°F).

Choice B rationale

Acrocyanosis, a bluish discoloration of the hands and feet, is a common and usually benign finding in newborns, especially in the first 24-48 hours, due to immature peripheral circulation. It does not directly indicate hypoglycemia; rather, it reflects normal physiological adaptation to extrauterine life.

Choice C rationale

Jitteriness, or tremors, is a classic neurological sign of hypoglycemia in newborns. The central nervous system is highly dependent on glucose for energy, and insufficient glucose supply can lead to neuronal excitability and involuntary muscle movements. This is often an early and prominent symptom.

Choice D rationale

Hypotonia, characterized by decreased muscle tone and floppiness, can be a symptom of severe or prolonged hypoglycemia. Glucose is essential for proper neuromuscular function, and its deprivation can impair nerve impulse transmission and muscle contraction, leading to reduced muscle resistance to passive movement.

Choice E rationale

Abdominal distention is typically associated with gastrointestinal issues such as feeding intolerance, bowel obstruction, or necrotizing enterocolitis. It is not a direct or common manifestation of hypoglycemia in newborns. Hypoglycemia primarily affects metabolic and neurological systems.
