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. A nurse is evaluating the effectiveness of teaching regarding care of a child with minimal change nephrotic syndrome (MCNS) that is in remission after administration of prednisone. The nurse realizes further teaching is required if the parents state what?

• A. We will keep our child away from anyone who is ill.
• B. We will be sure to administer the prednisone as ordered.
• C. We will encourage our child to eat a balanced diet, but we will watch his salt intake.
• D. We understand our child will not be able to attend school, so we will arrange for home schooling.

Correct answer: D

Rationale: Children with MCNS in remission can usually return to school. Home schooling may be necessary only if there are complications. The other options show an understanding of proper care during remission.

3. Physiological anorexia in toddlerhood occurs because of:

• A. Decreased appetite and decreased nutritional need
• B. Decreased appetite and increased nutritional need
• C. Increased appetite and lack of food preferences
• D. Increased appetite and strong food preferences

Correct answer: A

Rationale: Physiological anorexia in toddlers occurs due to a decreased appetite as growth rates slow down. Choice A is correct because it aligns with the concept that toddlers experience a natural decrease in appetite as their growth rate decreases. Choices B, C, and D are incorrect because they suggest increased appetite or other factors not associated with physiological anorexia in toddlerhood.

4. 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.

5. The nurse is providing education to the parent of a child with Beta-thalassemia. Which risk factors about the condition should the nurse include in the teaching?

• A. Hypertrophy of the thyroid
• B. Polycythemia vera
• C. Thrombocytopenia
• D. Chronic hypoxia and iron overload

Correct answer: D

Rationale: The correct answer is D: Chronic hypoxia and iron overload. Children with Beta-thalassemia often suffer from chronic hypoxia due to ineffective erythropoiesis and require frequent blood transfusions, leading to iron overload. These complications must be managed to prevent organ damage. Choices A, B, and C are incorrect. Hypertrophy of the thyroid, polycythemia vera, and thrombocytopenia are not direct risk factors associated with Beta-thalassemia. Therefore, they should not be included in the teaching regarding this condition.
