Nursing Elites

1. What type of dehydration occurs when the electrolyte deficit exceeds the water deficit?

• A. Isotonic dehydration
• B. Hypotonic dehydration
• C. Hypertonic dehydration
• D. Hyperosmotic dehydration

Correct answer: B

Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.

2. What is an approximate method of estimating output for a child who is not toilet trained?

• A. Have parents estimate output.
• B. Weigh diapers after each void.
• C. Place a urine collection device on the child.
• D. Have the child sit on a potty chair 30 minutes after eating.

Correct answer: B

Rationale: Weighing diapers is the most accurate way to estimate urine output in a child who is not toilet trained. This method provides a measurable and reliable estimate of fluid output.

3. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

4. The nurse is planning an educational session with a group of school-age children. Which primary task from Erikson’s theory of psychosocial development should be addressed?

• A. Establishing trust in others
• B. Developing a sense of autonomy
• C. Developing a sense of industry
• D. Establishing a sense of identity

Correct answer: C

Rationale: In Erikson’s theory of psychosocial development, school-age children typically focus on developing a sense of industry. This stage, occurring during middle childhood, involves the desire to feel competent and productive in their skills and abilities. Choices A, B, and D are incorrect because establishing trust in others (A) is related to the first stage of Erikson's theory (trust vs. mistrust) which occurs in infancy, developing a sense of autonomy (B) is linked to the second stage (autonomy vs. shame and doubt) which occurs in early childhood, and establishing a sense of identity (D) is associated with the fifth stage (identity vs. role confusion) which occurs in adolescence.

5. What problem is most often associated with myelomeningocele?

• A. Biliary atresia
• B. Hydrocephalus
• C. Craniostenosis
• D. Tracheoesophageal fistula

Correct answer: B

Rationale: Hydrocephalus is the most commonly associated problem with myelomeningocele, present in 80% to 90% of affected children. Biliary atresia and tracheoesophageal fistula are not typically associated with myelomeningocele. Craniostenosis refers to the premature closing of cranial sutures and is not a common issue seen with myelomeningocele.
