A nurse is collecting a blood phenylketonuria (PKU) test for a newborn prior to discharge.The newborn's guardian asks the nurse what a positive PKU test would mean.
Which of the following statements should the nurse make?
A positive finding indicates the inability to metabolize galactose.
A positive finding indicates the infant will have a slow metabolism.
A positive finding indicates an inability to metabolize certain amino acids.
A positive finding indicates an increased risk for neurological anomalies.
The Correct Answer is C
Choice A rationale
A positive finding for galactosemia, not PKU, indicates the inability to metabolize galactose. Galactosemia is a different metabolic disorder that requires a separate dietary intervention.
Choice B rationale
A positive PKU test does not indicate slow metabolism. Instead, it signifies the inability to metabolize phenylalanine, an amino acid.
Choice C rationale
Phenylketonuria (PKU) is a genetic disorder that leads to the inability to break down the amino acid phenylalanine. Without proper management, it can accumulate in the body and cause brain damage and other health issues.
Choice D rationale
A positive PKU test is not directly linked to an increased risk for neurological anomalies in general. The specific issue in PKU is the inability to metabolize certain amino acids, primarily phenylalanine, which can cause neurological damage if untreated. .

Correct Answer is A
Explanation
Choice A rationale
Checking fetal heart tones is the priority to assess the well-being of the fetus, especially in breech presentation and after the membranes have ruptured.
Choice B rationale
Preparing for a cesarean birth is important but follows the assessment of fetal heart tones and other immediate measures.
Choice C rationale
Checking the color, amount, and odor of the fluid is important, but ensuring fetal heart tones comes first to monitor any distress.
Choice D rationale
Performing a Nitrazine test to assess for rupture of membranes is redundant once the client reports her water has broken.
Correct Answer is A
Explanation
Choice A rationale
Rear-facing car seats are safer for infants and toddlers because they provide better support for their head, neck, and spine in the event of a collision. The American Academy of Pediatrics recommends keeping children in rear-facing seats until they are at least 2 years old or until they reach the highest weight or height allowed by the manufacturer.
Choice B rationale
A four-point harness is not sufficient for securing a baby in a car seat. A five-point harness, which includes two shoulder straps, two hip straps, and one crotch strap, provides more secure and effective restraint for infants.
Choice C rationale
The shoulder harness should be positioned in the slots at or below the baby's shoulders, not above, to ensure proper fit and restraint. Placing the harness above the shoulders can result in improper restraint and increased risk of injury in an accident.
Choice D rationale
The correct angle for a rear-facing car seat is typically 45 degrees, not 30 degrees. A 45-degree angle ensures the baby's airway remains open, preventing the head from falling forward and potentially causing breathing difficulties.
