1. Melena, the passage of black, tarry stools, suggests bleeding from which source?

• A. The perianal or rectal area
• B. The upper gastrointestinal (GI) tract
• C. The lower GI tract
• D. Hemorrhoids or anal fissures

Correct answer: B

Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.

2. What statement is an advantage of peritoneal dialysis compared with hemodialysis?

• A. Protein loss is less extensive.
• B. Dietary limitations are not necessary.
• C. It is easy to learn and safe to perform.
• D. It is needed less frequently than hemodialysis.

Correct answer: C

Rationale: Peritoneal dialysis is generally easier to learn and can be safely performed at home. Although dietary limitations still apply, this method offers greater flexibility in treatment scheduling compared to hemodialysis, which often requires multiple weekly visits to a dialysis center.

3. Which parental statement at the conclusion of a teaching session regarding environmental controls for childhood asthma indicates correct understanding of the information presented?

• A. ''We're glad the dog can continue to sleep in our child’s room.''
• B. ''We’ll keep the plants in our child’s room dusted.''
• C. ''We’ll be sure to use the fireplace often to keep the house warm in the winter.''
• D. ''We will replace the carpet in our child’s bedroom with a hard surface.''

Correct answer: D

Rationale: The correct answer is D. Replacing carpet with hard flooring helps to reduce allergens and asthma triggers in the child’s environment. Choice A is incorrect as having a dog in the child’s room can worsen asthma symptoms due to pet dander. Choice B is incorrect because keeping plants in the child’s room can increase mold spores and allergens. Choice C is incorrect as using a fireplace can introduce smoke and other irritants into the air, worsening asthma symptoms.

4. What factor predisposes an infant to fluid imbalances?

• A. Decreased surface area
• B. Lower metabolic rate
• C. Immature kidney functioning
• D. Decreased daily exchange of extracellular fluid

Correct answer: C

Rationale: Infants have immature kidneys that are less efficient at concentrating urine, making them more susceptible to fluid imbalances. Their higher surface area to volume ratio also contributes to greater insensible fluid losses.

5. Pretending a sheet is a cape to mimic a superhero is characteristic of which childhood phenomenon?

• A. Artificialism
• B. Symbolic functioning
• C. Critical thinking
• D. Dramatic play

Correct answer: B

Rationale: The correct answer is B, symbolic functioning. Symbolic functioning refers to children using objects, actions, or ideas to represent other objects, actions, or ideas. In this scenario, pretending a sheet is a cape to mimic a superhero demonstrates the child's ability to engage in symbolic play. Choice A, artificialism, is incorrect as it refers to the belief that inanimate objects have lifelike qualities. Choice C, critical thinking, does not directly relate to the imaginative play described in the question. Choice D, dramatic play, is close but not as precise as symbolic functioning, which specifically highlights the use of objects to represent something else.
