1. A newborn with an anorectal anomaly had an anoplasty performed. At the 2-week follow-up visit, a series of anal dilations is begun. What should the nurse recommend to the parents to help prevent the infant from becoming constipated?
- A. Use a soy formula if necessary.
- B. Breastfeed if possible.
- C. Avoid administering a suppository nightly.
- D. Do not offer glucose water between feedings.
Correct answer: B
Rationale: Breastfeeding is recommended to help prevent constipation in infants due to the easily digestible nature of breast milk, which often leads to softer stools. Breastfeeding is preferred over formula feeding as it provides optimal nutrition for the infant's digestive system. Choice A, using a soy formula if necessary, may be considered only if there are specific dietary concerns or allergies; however, breast milk is still the preferred option. Choice C, avoiding administering a suppository nightly, is correct as it is not a routine method for preventing constipation in infants and may not be appropriate without medical advice. Choice D, not offering glucose water between feedings, is recommended as it may not address the root cause of constipation and may introduce unnecessary sugar to the infant's diet.
2. After the nurse has completed an oral examination of a healthy 2-year-old child, the parent asks when the child should first be taken to the dentist. When is the most appropriate time in the child’s life for the nurse to suggest?
- A. Before starting school
- B. Within the next few months
- C. When the first deciduous teeth are lost
- D. At the next dental check-up for a family member
Correct answer: B
Rationale: The most appropriate time for a child to first visit the dentist is within the next few months after turning two years old. This visit allows the dentist to assess the child's oral health, provide guidance on proper oral hygiene practices, and establish a positive relationship with dental care. Choice A (Before starting school) is not as specific and timely as the recommended age of 2 years. Choice C (When the first deciduous teeth are lost) is not ideal as preventive dental visits should start earlier to establish good oral health habits. Choice D (At the next dental check-up for a family member) may delay the child's first dental visit, missing the opportunity for early preventive care and guidance.
3. Your assessment of a mother in active labor reveals that a limb is protruding from the vagina. Management of this condition should include:
- A. Positioning the mother in a semi-Fowler's position, administering oxygen, and providing transport
- B. Positioning the mother in a head-down position with her hips elevated, administering oxygen, and providing transport
- C. Applying gentle traction to the protruding limb to remove pressure of the fetus from the umbilical cord
- D. Giving the mother 100% oxygen and attempting to manipulate the protruding limb so that delivery can occur
Correct answer: B
Rationale: In a situation where a limb is protruding from the vagina during active labor, the correct management includes positioning the mother in a head-down position with her hips elevated. This position helps relieve pressure on the umbilical cord and improves oxygenation to the fetus. Administering oxygen is important to ensure adequate oxygen supply to both the mother and the baby. Providing transport is necessary for prompt transfer to a medical facility for further management. Applying gentle traction to the protruding limb is not recommended as it can cause harm to the baby and should be avoided. Giving 100% oxygen and attempting to manipulate the protruding limb is not the correct approach and can potentially lead to further complications.
4. A child who had surgery for a congenital heart defect is being discharged. What is an important aspect of the discharge teaching?
- A. Teaching the parents about signs of infection
- B. Providing instructions on wound care
- C. Scheduling follow-up appointments
- D. Explaining the use of prescribed medications
Correct answer: D
Rationale: Explaining the use of prescribed medications is crucial as it helps ensure the proper management of the child's condition post-discharge. Understanding how and when to administer medications is essential for the child's recovery. While teaching the parents about signs of infection, providing wound care instructions, and scheduling follow-up appointments are also important aspects of care, ensuring the correct use of prescribed medications takes precedence to prevent complications and promote the child's well-being.
5. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:
- A. nondisjunction.
- B. X-linked recessive inheritance.
- C. genomic imprinting.
- D. autosomal dominant inheritance.
Correct answer: A
Rationale: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.
