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. During a vaccination drive at a well-child clinic, a nurse observes that a recently hired nurse is not wearing gloves. What should the nurse advise the newly hired nurse to do?
- A. Speak with the nurse manager regarding techniques.
- B. Put on gloves because standard precautions are required.
- C. Continue with the immunizations because gloves are not needed.
- D. Evaluate the child’s appearance to determine whether gloves are needed.
Correct answer: B
Rationale: The correct answer is B: Put on gloves because standard precautions are required. Standard precautions, which include wearing gloves, are crucial in preventing the transmission of infections during immunization. Choice A is incorrect because the immediate action should be to address the lack of gloves. Choice C is incorrect as gloves are necessary for infection control. Choice D is incorrect as gloves should be worn as a standard preventive measure, regardless of the child's appearance.
3. What behavior does a toddler subjected to prolonged hospitalization with limited parental visits typically exhibit?
- A. Engage in cheerful interactions with staff members
- B. Display indications of sadness throughout the day
- C. Experience excessive crying when parents are not present
- D. Show limited emotional response to the environment
Correct answer: D
Rationale: Toddlers subjected to prolonged hospitalization with limited parental visits usually exhibit a limited emotional response to the environment. This behavior can be a coping mechanism for the child in dealing with the separation from their primary caregivers. The child might not show the same level of engagement or emotional expression as they would if their parents were present. Choices A, B, and C are less likely because the child's emotional response is typically more subdued and withdrawn in such circumstances, rather than being cheerful, consistently sad, or excessively crying.
4. A group of nursing students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?
- A. Regulation of water balance
- B. Hormonal secretion
- C. Cellular metabolism
- D. Growth stimulation
Correct answer: B
Rationale: The correct answer is 'Hormonal secretion' (Choice B). The primary function of the endocrine system is to secrete hormones that regulate various bodily functions such as metabolism, growth, and reproduction. Choice A, 'Regulation of water balance,' is primarily controlled by the kidneys and the urinary system, not the endocrine system. Choice C, 'Cellular metabolism,' is more directly related to the functions of individual cells rather than the overall function of the endocrine system. Choice D, 'Growth stimulation,' is a function that can be influenced by hormones secreted by the endocrine system, but it is not the primary function of the system.
5. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?
- A. Mental retardation occurs if PKU is untreated.
- B. Testing for PKU is done immediately after birth.
- C. Treatment for PKU includes lifelong dietary management.
- D. PKU is transmitted by an autosomal recessive gene.
Correct answer: A
Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that, if left untreated with dietary management, can lead to severe mental retardation due to the accumulation of phenylalanine. It is crucial for parents to understand the potential consequences of untreated PKU to emphasize the importance of early and consistent treatment. Choice B is incorrect because testing for PKU is typically done through newborn screening shortly after birth, not immediately. Choice C is incorrect as treatment for PKU primarily involves strict dietary management that restricts phenylalanine intake, not lifelong medications. Choice D is incorrect as PKU is inherited in an autosomal recessive pattern, meaning that both parents must pass on a mutated gene for the disorder to manifest.
