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 first sign of puberty in girls?

• A. Acne
• B. Hair growth in the pubic area and underarms
• C. Thelarche
• D. Menarche

Correct answer: C

Rationale: The correct answer is C, Thelarche. Thelarche refers to the onset of breast development, which is typically the first sign of puberty in girls. This occurs before menarche (the first menstrual period). Choices A and B, acne and hair growth in the pubic area and underarms, are not the first signs of puberty in girls. While acne can be a common occurrence during puberty, it usually appears after other physical changes. Hair growth in the pubic area and underarms also occurs later in the puberty process.

3. Which electrolyte imbalance is a common concern in children with severe diarrhea?

• A. Hypernatremia
• B. Hypokalemia
• C. Hypercalcemia
• D. Hypomagnesemia

Correct answer: B

Rationale: Hypokalemia is the correct answer because it is a common concern in children with severe diarrhea. Diarrhea can lead to significant potassium loss, resulting in hypokalemia. Hypernatremia (Choice A) is less common in diarrhea as sodium concentration is usually diluted by the fluid loss. Hypercalcemia (Choice C) is not typically associated with severe diarrhea. Hypomagnesemia (Choice D) can occur but is not as common as hypokalemia in this scenario.

4. For minimal change nephrotic syndrome (MCNS), prednisone is effective when what occurs?

• A. Appetite increases and blood pressure is normal
• B. Urinary tract infection is gone and edema subsides
• C. Generalized edema subsides and blood pressure is normal
• D. Diuresis occurs as urinary protein excretion diminishes

Correct answer: D

Rationale: The effectiveness of prednisone in treating MCNS is indicated by diuresis and a decrease in urinary protein excretion. Subsidence of generalized edema is also a positive sign, but the key indicator is the reduction in proteinuria, which is achieved through diuresis.

5. The parents of a 2-year-old boy who had a repair of exstrophy of the bladder at birth ask when they can begin toilet training their son. The nurse replies based on what knowledge?

• A. Most boys in the United States can be toilet trained at age 3 years.
• B. Training can begin when he has sufficient bladder capacity.
• C. Additional surgery may be necessary to achieve continence.
• D. They should begin now because he will require additional time.

Correct answer: B

Rationale: Toilet training should begin when the child has sufficient bladder capacity and control, which may be delayed in children who have undergone surgical repairs for conditions like bladder exstrophy. Premature training can lead to frustration and setbacks.
