Nursing Elites

1. A parent tells the nurse, “My 9-month-old baby no longer has the same strong grasp that was present at birth and no longer acts startled by loud noises.” How should the nurse explain these changes in behavior?

• A. “I will check these responses before deciding how to proceed.”
• B. “Failure of these responses may be related to a developmental delay.”
• C. “Additional sensory stimulation is needed to aid in the return of these responses.”
• D. “These responses are replaced by voluntary activity at about five months of age.”

Correct answer: D

Rationale: The correct answer is D: “These responses are replaced by voluntary activity at about five months of age.” The grasp reflex and startle reflex (Moro reflex) are normal in newborns but typically disappear as the infant's nervous system matures and voluntary control develops. Choice A is incorrect because checking the responses before deciding a course of action does not address the developmental milestone related to the reflexes. Choice B is incorrect as it jumps to a conclusion of developmental delay without considering the normal developmental process. Choice C is incorrect as additional sensory stimulation is not necessary for the return of these reflexes, as they are expected to naturally diminish as part of normal development.

2. 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.

3. An infant with a congenital heart defect is being given gavage feedings. The parents ask the nurse why this is necessary. How should the nurse respond?

• A. It limits the chance of vomiting.
• B. It allows the feeding to be administered rapidly.
• C. The energy that would have been expended on sucking is conserved.
• D. The quantity of nutritional liquid can be regulated better than with a bottle.

Correct answer: C

Rationale: Gavage feedings are necessary for infants with congenital heart defects to conserve the infant's energy by eliminating the need for sucking. This is important because sucking requires energy expenditure, which can be taxing for infants with cardiac defects. Choice A is incorrect as gavage feedings do not primarily limit the chance of vomiting. Choice B is incorrect because the speed of feeding administration is not the primary reason for using gavage feedings in this case. Choice D is incorrect as the regulation of the quantity of nutritional liquid is not the main purpose of gavage feedings in infants with congenital heart defects.

4. The nurse is assessing a child with a possible fracture. What would the nurse identify as the most reliable indicator?

• A. Lack of spontaneous movement
• B. Point tenderness
• C. Bruising
• D. Inability to bear weight

Correct answer: B

Rationale: Point tenderness is the most reliable indicator of a possible fracture in a child. It is a localized tenderness experienced when pressure is applied to a specific area, suggesting a potential fracture. This tenderness is considered more specific to a fracture than other symptoms such as lack of spontaneous movement, bruising, or inability to bear weight. Lack of spontaneous movement and inability to bear weight can be present in various musculoskeletal injuries, while bruising may not always be immediate or specific to a fracture.

5. What type of play does a caregiver expect when observing a toddler in a playroom with other children?

• A. Parallel
• B. Solitary
• C. Cooperative
• D. Competitive

Correct answer: A

Rationale: When observing a toddler in a playroom with other children, a caregiver would expect to witness parallel play. Parallel play is common among toddlers, where they play alongside but not directly with other children. This type of play is characterized by children engaging in similar activities near each other without interactive or cooperative play. Solitary play (Choice B) involves a child playing alone, while cooperative play (Choice C) involves children playing together towards a common goal. Competitive play (Choice D) involves activities where children compete against each other.
