1. 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.

2. The nurse is caring for an adolescent who is overweight. Which of the following psychological effects of being overweight during adolescence will the nurse consider when planning care for the adolescent?

• A. Poor body image
• B. Sexual promiscuity
• C. Feelings of contempt for thin peers
• D. Lack of independence

Correct answer: A

Rationale: Adolescents who are overweight often struggle with poor body image, which can lead to low self-esteem and mental health issues. Addressing body image concerns and promoting healthy lifestyle changes are important aspects of care. Choices B, C, and D are incorrect. Sexual promiscuity is not a direct psychological effect of being overweight; feelings of contempt for thin peers are not a common or recommended psychological response; lack of independence is a broad term that does not specifically relate to the psychological effects of being overweight.

3. The parent of an 8.2-kg (18-lb) 9-month-old infant is borrowing a federally approved car seat from the clinic. The nurse should explain that the safest way to put in the car seat is what?

• A. Front facing in back seat
• B. Rear facing in back seat
• C. Front facing in front seat with air bag on passenger side
• D. Rear facing in front seat if an air bag is on the passenger side

Correct answer: B

Rationale: Infants should be placed rear-facing in the back seat until they are at least 2 years old or exceed the weight/height limit of their car seat for optimal safety.

4. In which type of cancer are the urinary excretion of the breakdown products of catecholamines, especially vanillylmandelic acid (VMA) and homovanillic acid (HVA), detected?

• A. Neuroblastoma
• B. Nephroblastoma
• C. Leukemia
• D. Osteosarcoma

Correct answer: A

Rationale: The correct answer is A: Neuroblastoma. Neuroblastoma, a cancer that arises from nerve tissue, is associated with increased levels of catecholamine metabolites, including VMA and HVA, in the urine. Nephroblastoma (Wilms tumor) is a type of kidney cancer and is not typically associated with elevated levels of catecholamine breakdown products. Leukemia is a cancer of the blood and bone marrow and does not lead to increased VMA and HVA excretion in urine. Osteosarcoma is a bone cancer and is not linked to elevated levels of catecholamine metabolites in the urine.

5. A Hispanic toddler has pneumonia. The nurse notices that the parent consistently feeds the child only the broth that comes on the clear liquid tray. Food items, such as Jell-O, Popsicles, and juices, are left. Which statement best explains this?

• A. The parent is trying to feed the child only what the child likes most
• B. Hispanics believe the evil eye enters when a person gets cold
• C. The parent is trying to restore normal balance through appropriate hot remedies
• D. Hispanics believe an innate energy called chi is strengthened by eating soup

Correct answer: C

Rationale: In Hispanic culture, the balance between hot and cold is important, and the parent may be giving the child broth to restore this balance while avoiding "cold" foods.
