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 diagnostic test allows visualization of renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes?

• A. Renal ultrasonography
• B. Computed tomography
• C. Intravenous pyelography
• D. Voiding cystourethrography

Correct answer: A

Rationale: Renal ultrasonography provides imaging of the renal parenchyma and pelvis without the risks associated with radiation or radioactive isotopes, making it a safer option, especially for children.

3. 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.

4. A parent brings their 4-year-old child for a check-up. Which finding would concern the nurse?

• A. Ectomorphic body type
• B. Resting pulse rate of 120
• C. Weight gain of 5 lb (2.27 kg) in the past year
• D. No increase in appetite compared with that in toddler years

Correct answer: B

Rationale: A resting pulse rate of 120 is elevated for a 4-year-old and may indicate an underlying issue that needs further investigation. An ectomorphic body type is a body shape and not typically a cause for concern. Weight gain within normal limits and no significant change in appetite are generally positive findings in a growing child.

5. The nurse is preparing to admit a 7-year-old child with Crohn disease. What clinical manifestations should the nurse expect to observe?

• A. Pain is common.
• B. Weight loss is severe.
• C. All are correct.
• D. Diarrhea is moderate to severe.

Correct answer: C

Rationale: The correct answer is C because Crohn's disease commonly presents with pain, severe weight loss, and moderate to severe diarrhea in affected individuals. Therefore, all the manifestations listed are typically observed in patients with Crohn's disease. Choice A alone is not sufficient as weight loss and diarrhea are also prominent symptoms. Choice B is incorrect as it only mentions weight loss, omitting other common manifestations. Choice D is also incorrect as it does not cover the full range of expected clinical signs in Crohn's disease.
