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. Which nursing action is developmentally appropriate when caring for a hospitalized school-age child?

• A. Providing brochures regarding sexuality
• B. Giving clear instructions about details of treatment
• C. Offering medical equipment to play with prior to a procedure
• D. Using toys for distraction during a painful procedure

Correct answer: C

Rationale: Offering medical equipment to play with prior to a procedure is developmentally appropriate when caring for a hospitalized school-age child. Allowing the child to familiarize themselves with the equipment helps reduce fear and anxiety about the upcoming procedure. Choices A, B, and D are not as appropriate for a school-age child. Providing brochures regarding sexuality is not developmentally appropriate for this age group. Giving clear instructions about treatment details may overwhelm a child of this age. Using toys for distraction during a painful procedure is more suitable for younger children.

3. 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.

4. What term describes the invagination of one segment of bowel within another?

• A. Atresia
• B. Stenosis
• C. Herniation
• D. Intussusception

Correct answer: D

Rationale: Intussusception is the correct answer. It refers to the condition where one segment of the bowel folds into another, leading to an obstruction. Atresia (Choice A) is the absence or abnormal closure of a normal opening or tubular structure. Stenosis (Choice B) is the narrowing of a passage in the body. Herniation (Choice C) is the abnormal protrusion of an organ or tissue through a defect in its surrounding walls. Intussusception is a medical emergency commonly observed in infants and young children and necessitates prompt intervention to prevent severe complications.

5. The educator is teaching about the process of physical growth and development. Which of these describes the directional pattern from head to tail?

• A. Cephalodistal
• B. Cephalocaudal
• C. Proximodistal
• D. Proximocaudal

Correct answer: B

Rationale: Cephalocaudal development is the correct term that describes the directional pattern of growth from head to tail. This means that the head and upper body parts develop before the lower parts. Choice A, 'Cephalodistal,' refers to growth from the center of the body outward, not head to tail. Choice C, 'Proximodistal,' describes growth from the center of the body towards the extremities, not specifically from head to tail. Choice D, 'Proximocaudal,' is not a recognized term in the context of physical growth and development.
