Nursing Elites

1. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

2. Which of the following is a key feature of autism spectrum disorder?

• A. Delayed speech development
• B. Hyperactivity
• C. Lack of interest in toys
• D. Aggressive behavior

Correct answer: A

Rationale: Delayed speech development is a significant feature of autism spectrum disorder. Many children with autism exhibit delays in speech and language development, which can be one of the early signs of the condition. Hyperactivity, lack of interest in toys, and aggressive behavior are not key defining features of autism spectrum disorder. While some individuals with autism may exhibit these behaviors, they are not universally characteristic of the disorder.

3. The nurse is providing anticipatory guidance to the parent of a 9-month-old infant during a well-baby visit. Which topic would be most appropriate?

• A. Cautioning about putting the infant in a walker
• B. Advising how to create a toddler-safe home
• C. Instructing on safety procedures during baths
• D. Warning about leaving small objects on the floor

Correct answer: D

Rationale: The correct answer is D because at 9 months, infants become more mobile, increasing the risk of choking hazards from small objects left on the floor. Cautioning about putting the infant in a walker (Choice A) is not as crucial at this age as warning about choking hazards. While advising how to create a toddler-safe home (Choice B) is essential, the most critical concern at 9 months is small objects. Instructing on safety procedures during baths (Choice C) is important but does not address the immediate risk of choking hazards associated with small objects.

4. The nurse is teaching parents about diarrhea in young children. A parent asks the nurse what causes most cases of diarrhea in young children. How should the nurse respond?

• A. Rotavirus
• B. Giardia
• C. Shigella
• D. Salmonella

Correct answer: A

Rationale: Rotavirus is the most common cause of diarrhea in young children, particularly those under the age of 2. Giardia, Shigella, and Salmonella can also cause diarrhea, but in the context of young children, Rotavirus is the primary pathogen responsible for diarrheal illnesses.

5. The mother of a 6-year-old boy who has recently had surgery for the removal of his tonsils and adenoids complains that he has begun sucking his thumb again. Which defense mechanism should the nurse include when responding to the mother?

• A. Repression
• B. Regression
• C. Rationalization
• D. Fantasy

Correct answer: B

Rationale: The correct answer is B: Regression. Regression is a common defense mechanism where a child reverts to an earlier stage of development, such as thumb-sucking, to cope with stress. In this scenario, the 6-year-old boy is using thumb-sucking (a behavior typical of earlier developmental stages) as a way to deal with the stress of surgery. Repression (choice A) involves unconsciously blocking out thoughts or feelings, which is not applicable in this case. Rationalization (choice C) is a defense mechanism where illogical or unreasonable explanations are provided to justify behavior, which is not relevant here. Fantasy (choice D) refers to the use of imagination to escape from reality, which is also not the appropriate defense mechanism for the situation described.
