Nursing Elites

1. Ongoing fluid losses can overwhelm the child’s ability to compensate, resulting in shock. What early clinical sign precedes shock?

• A. Tachycardia
• B. Slow respirations
• C. Warm, flushed skin
• D. Decreased blood pressure

Correct answer: A

Rationale: Tachycardia is an early sign of shock as the body tries to maintain cardiac output in the face of declining circulatory volume. Blood pressure often remains normal until late in the progression, at which point decompensated shock is occurring.

2. 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.

3. The predominant characteristic of the intellectual development of a child aged 2 to 7 years is egocentricity. Which of the following best describes this concept?

• A. Selfishness
• B. Unable to see another’s point of view
• C. Able to put self in another’s place
• D. Prefers to play alone

Correct answer: B

Rationale: Egocentricity in children aged 2 to 7 years means they are unable to see things from another person's perspective. This characteristic is a normal part of their cognitive development during this stage. Choice A, 'Selfishness,' is not an accurate description as egocentricity is more about a limited ability to understand others' viewpoints rather than intentional selfishness. Choice C, 'Able to put self in another’s place,' is incorrect as egocentric children struggle to do this. Choice D, 'Prefers to play alone,' is not directly related to egocentricity but may be a behavior exhibited by some children for various reasons.

4. 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.

5. The caregiver asks why the 6-month-old infant needs to have solid foods when breast milk is such a good source of nutrition. What would be the best response by the nurse?

• A. Solid foods, especially iron-fortified cereals, are introduced to meet the infant's increased nutritional needs, including iron, which breast milk alone may not provide adequately.
• B. The extrusion reflex must be developed and feeding solid foods will help the infant to develop this reflex.
• C. Breastfeeding will become painful when the infant gets more teeth, so the infant needs to eat solid foods.
• D. By this age the infant becomes interested in trying new skills.

Correct answer: A

Rationale: The correct response is A. Solid foods, especially iron-fortified cereals, are introduced to meet the infant's increased nutritional needs, including iron, which breast milk alone may not provide adequately. Choice B is incorrect because the extrusion reflex is related to the tongue-thrust reflex, not the nutritional needs of the infant. Choice C is incorrect as breastfeeding does not become painful when the infant gets more teeth, and it is not a reason for introducing solid foods. Choice D is incorrect as the infant's interest in trying new skills is not a primary reason for introducing solid foods at this age.
