1. Which additional congenital malformation is expected in 80% of infants with a myelomeningocele?

A. Cerebral palsy
B. Hydrocephalus
C. Meningitis
D. Neuroblastoma

Correct answer: B

Rationale: Hydrocephalus is the additional congenital malformation expected in 80% of infants with a myelomeningocele. Myelomeningocele is commonly associated with hydrocephalus due to the abnormal accumulation of cerebrospinal fluid in the brain. Cerebral palsy (Choice A) is a motor disorder but not typically associated with myelomeningocele. Meningitis (Choice C) is an infection of the meninges and is not a congenital malformation. Neuroblastoma (Choice D) is a type of cancer that originates in immature nerve cells and is not a typical association with myelomeningocele.

2. The nurse instructs the mother of a child with a ventricular septal defect that she can expect the child to become cyanotic when the child does what?

A. Experiences an elevation in temperature.
B. Sleeps on the left side.
C. Cries vigorously.
D. Eats.

Correct answer: C

Rationale: The correct answer is C: Cries vigorously. When the child cries vigorously, it increases the pressure in the right ventricle, allowing unoxygenated blood to enter the circulating volume, leading to cyanosis. This occurs due to the shunting of blood from the right side of the heart to the left side through the ventricular septal defect. Choices A, B, and D are incorrect because they do not directly impact the pressure in the right ventricle, which is crucial in causing cyanosis in this scenario.

3. While performing a skin assessment on an older adult, the nurse notices a number of irregular round brownish-colored lesions on the client’s hands, arms, and face. On palpation, they are flat and slightly rough to the touch. Based on this assessment finding, which action should the nurse implement?

A. Apply a topical antibiotic ointment.
B. Monitor the lesions for changes.
C. Advise the client to use sunscreen.
D. Refer the client for a skin lesion biopsy.

Correct answer: D

Rationale: Referral for a skin biopsy is necessary to rule out potential malignancy of irregular skin lesions. Applying a topical antibiotic ointment (Choice A) is not indicated for irregular pigmented lesions. Monitoring the lesions for changes (Choice B) may delay appropriate intervention if malignancy is present. Advising the client to use sunscreen (Choice C) is important for sun protection but is not the priority when irregular lesions are present.

4. When conducting a class for parents about sudden infant death syndrome (SIDS), the nurse instructs the class that the infant should be placed in which position to sleep?

A. Right side-lying
B. Left side-lying
C. Prone
D. Supine

Correct answer: D

Rationale: The correct answer is D, supine. The American Academy of Pediatrics recommends placing infants on their back, or supine, to sleep as it has been shown to reduce the risk of SIDS. Choices A, B, and C are incorrect because placing infants on their right side, left side, or prone (on their stomach) respectively are not recommended sleeping positions due to the increased risk of SIDS associated with those positions.

5. Since children with attention deficit hyperactivity disorder (ADHD) take medication for long periods of time, side effects must be considered. How often should children be assessed for side effects of the drug therapy?

A. Every 2 months
B. Every 4 months
C. Every 6 months
D. Every 8 months

Correct answer: C

Rationale: Children with ADHD who are on long-term medication therapy should be assessed for side effects every 6 months. This timeframe allows healthcare providers to monitor the effects of the medication and make any necessary adjustments. Checking every 2 months (Choice A) may be too frequent and not practical for routine monitoring, while checking every 4 or 8 months (Choices B and D) may lead to missing potential side effects or delays in addressing them.
