1. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

2. During a prenatal visit, the LPN/LVN discusses with a client the effects of smoking on the fetus. When compared with nonsmokers, mothers who smoke during pregnancy tend to produce infants who have

• A. lower Apgar scores.
• B. lower birth weights.
• C. respiratory distress.
• D. a higher rate of congenital anomalies.

Correct answer: B

Rationale: When mothers smoke during pregnancy, it is associated with intrauterine growth restriction, which leads to lower birth weights in infants. Maternal smoking can restrict the flow of oxygen and nutrients to the fetus, affecting its growth and development. This can result in babies being born with lower birth weights, which can have various health implications for the newborn. Choices A, C, and D are incorrect as smoking during pregnancy is primarily linked to intrauterine growth restriction and lower birth weights in infants, rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

3. A primipara patient asks what is the best pet to have at home to share time with. Which pet is not recommended?

• A. Dog
• B. Cat
• C. Bird
• D. Fish

Correct answer: C

Rationale: Birds are not recommended as pets for a primipara patient due to potential health risks associated with bird droppings, feathers, and dander. These factors may pose a risk to the newborn's health and the mother's well-being. Additionally, some birds can be loud, which may disrupt the baby's sleep patterns. Therefore, it is advisable for primipara patients to consider pets like dogs, cats, or fish as they generally have lower associated risks in a household with a newborn. Dogs, cats, and fish are relatively safer options compared to birds for primipara patients due to their lower risk of transmitting infections, allergens, or causing disturbances that could affect the newborn or the mother.

4. In developing a teaching plan for expectant parents, the nurse plans to include information about when the parents can expect the infant's fontanels to close. The LPN/LVN bases the explanation on knowledge that for the normal newborn, the

• A. anterior fontanel closes at 2 to 4 months and the posterior by the end of the first week.
• B. anterior fontanel closes at 5 to 7 months and the posterior by the end of the second week.
• C. anterior fontanel closes at 8 to 11 months and the posterior by the end of the first month.
• D. anterior fontanel closes at 12 to 18 months and the posterior by the end of the second month.

Correct answer: D

Rationale: The anterior fontanel typically closes between 12 to 18 months, while the posterior fontanel usually closes by the end of the second month. It is important for parents to know these timeframes as it helps in monitoring the normal growth and development of their newborn. Delayed closure of fontanels may indicate potential health issues, and early closure may also warrant further evaluation by healthcare providers.

5. A 3-month-old with myelomeningocele and atonic bladder is catheterized every 4hrs to prevent urinary retention. The home health nurse notes that the child has developed episodes of sneezing, urticarial, watery eyes, and a rash in the diaper area. What action is most important for the nurse to take?

• A. Auscultate the lungs for respiratory pneumonia.
• B. Change to latex-free gloves when handling infant.
• C. Draw blood to analyze for streptococcal infection.
• D. Apply zinc oxide to perineum with each diaper change.

Correct answer: B

Rationale: Latex allergy is a concern in patients with myelomeningocele, so switching to latex-free gloves is important.
