1. Which assessment findings should the nurse expect in a child with sickle cell anemia experiencing an acute vaso-occlusive crisis?

• A. Circulatory collapse, hypovolemia
• B. Cardiomegaly, systolic murmur
• C. Hepatomegaly, intrahepatic cholestasis
• D. Painful swelling of joints in hands and feet, tissue engorgement

Correct answer: D

Rationale: The correct answer is D. Vaso-occlusive crises in sickle cell anemia are characterized by painful swelling of the joints in the hands and feet (hand-foot syndrome) and tissue engorgement due to the obstruction of blood flow by sickled cells. Choices A, B, and C are incorrect because circulatory collapse, hypovolemia, cardiomegaly, systolic murmur, hepatomegaly, and intrahepatic cholestasis are not typically associated with an acute vaso-occlusive crisis in sickle cell anemia.

2. What is an advantage of the ventrogluteal muscle as an injection site in young children?

• A. Easily accessible from many directions
• B. Free of significant nerves and vascular structures
• C. Can be used until the child reaches a weight of 9 kg (20 lb)
• D. Increased subcutaneous fat, which provides sustained drug absorption

Correct answer: B

Rationale: The ventrogluteal site is free of significant nerves and vascular structures, making it a safer choice for intramuscular injections in young children compared to other sites that may be more prone to complications.

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. What is typically the first sign of puberty in females?

• A. Breast development
• B. Menarche
• C. Pubic hair growth
• D. Axillary hair growth

Correct answer: A

Rationale: The correct answer is A: Breast development (thelarche) is usually the first sign of puberty in females, typically beginning between ages 8 and 13. This marks the start of puberty, followed by pubic hair growth, a growth spurt, and eventually menarche (the onset of menstruation). Pubic hair growth and axillary hair growth usually follow breast development in the sequence of pubertal changes. Therefore, the first noticeable change indicating the onset of puberty in females is the development of breast buds.

5. Which parameter correlates best with measurements of total muscle mass?

• A. Height
• B. Weight
• C. Skinfold thickness
• D. Upper arm circumference

Correct answer: D

Rationale: Upper arm circumference correlates best with total muscle mass because it includes both muscle and fat components, making it a reliable indicator of muscle mass.
