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 the purpose of using cimetidine (Tagamet) for gastroesophageal reflux?

• A. The medication reduces gastric acid secretion.
• B. The medication neutralizes the acid in the stomach.
• C. The medication increases the rate of gastric emptying time.
• D. The medication coats the lining of the stomach and esophagus.

Correct answer: A

Rationale: The correct answer is A. Cimetidine (Tagamet) is an H2 receptor antagonist that works by reducing gastric acid secretion. This action helps to decrease the acidity in the stomach, which in turn reduces the symptoms of gastroesophageal reflux. Choice B is incorrect because cimetidine does not neutralize acid but rather decreases its production. Choice C is incorrect as cimetidine does not affect the rate of gastric emptying time. Choice D is incorrect as cimetidine does not coat the lining of the stomach and esophagus but instead works to reduce gastric acid secretion.

3. What is the best initial intervention for a child experiencing moderate dehydration?

• A. Administer IV fluids
• B. Encourage oral rehydration
• C. Monitor vital signs
• D. Provide clear fluids

Correct answer: B

Rationale: The correct answer is B: Encourage oral rehydration. Oral rehydration is the first-line treatment for moderate dehydration in children. It helps restore fluid balance and electrolyte levels. Administering IV fluids (Choice A) is usually reserved for severe cases of dehydration where oral rehydration is not feasible or ineffective. Monitoring vital signs (Choice C) is important but should not replace the immediate need for rehydration. Providing clear fluids (Choice D) may not contain the necessary electrolytes required for effective rehydration.

4. The child is admitted to the hospital unit newly diagnosed with retinoblastoma. Which clinical manifestation does the nurse anticipate upon assessment?

• A. A white reflex
• B. Blue-tinged sclerae
• C. A red reflex
• D. Yellow-tinged sclerae

Correct answer: A

Rationale: The correct answer is A: A white reflex. The 'white reflex' or leukocoria is a common sign of retinoblastoma. It occurs when the light reflects off the tumor in the eye, giving the pupil a white appearance instead of the normal red reflex. Blue-tinged sclerae (choice B) and yellow-tinged sclerae (choice D) are not typical manifestations of retinoblastoma. A red reflex (choice C) is the normal reflection seen in the eye when light is shone on it and is not associated with retinoblastoma.

5. During a well-child checkup, the parent of a 5-year-old child reports the child seems much smaller than the 2 older siblings did at this same age. A review of the medical record reveals that the child is 44 inches tall and weighs 42 pounds. What information should be included in the response by the nurse?

• A. The weight of your child at this time is within normal limits for this age but the child is moderately taller than other children this age.
• B. Your child is within the acceptable range for height but the child is significantly smaller in weight for this age.
• C. Your child is within normal limits for weight but the child is slightly shorter in stature than other children this age.
• D. Your child is slightly taller than other children this age but the child’s weight is normal.

Correct answer: D

Rationale: The correct answer is D. The child is slightly taller than average, but the weight is within normal limits. This information should be reassuring to the parent and provides insights into normal growth patterns. Choice A is incorrect as it inaccurately states that the child is taller than other children this age. Choice B is incorrect because the child's weight is actually within normal limits. Choice C is incorrect as it inaccurately states that the child is shorter in stature than other children this age.
