Nursing Elites

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 is the primary treatment goal for a child with nephrotic syndrome?

• A. Reduce proteinuria
• B. Lower blood pressure
• C. Increase urine output
• D. Prevent infections

Correct answer: A

Rationale: The correct answer is A: Reduce proteinuria. In nephrotic syndrome, the primary treatment goal is to reduce proteinuria to prevent further kidney damage. Lowering blood pressure (choice B) is important in managing some types of kidney disease but is not the primary treatment goal in nephrotic syndrome. Increasing urine output (choice C) and preventing infections (choice D) are important aspects of supportive care but are not the primary treatment goal for nephrotic syndrome.

3. The parent of an infant with colic tells the nurse, "All this baby does is scream at me; it is a constant worry." What is the nurse's best action?

• A. Encourage the parent to verbalize feelings.
• B. Encourage the parent not to worry so much.
• C. Assess the parent for other signs of inadequate parenting.
• D. Reassure the parent that colic rarely lasts past age 9 months.

Correct answer: A

Rationale: Encouraging the parent to express their feelings is crucial in providing support and addressing the emotional challenges that colic can present. Reassuring the parent about the temporary nature of colic can also be helpful.

4. A 12-year-old child is injured in a bicycle accident. When considering the possibility of renal trauma, the nurse should consider what factor?

• A. Flank pain rarely occurs in children with renal injuries.
• B. Few nonpenetrating injuries cause renal trauma in children.
• C. Kidneys are immobile, well protected, and rarely injured in children.
• D. The amount of hematuria is not a reliable indicator of the seriousness of renal injury.

Correct answer: D

Rationale: The amount of hematuria is not a reliable indicator of the severity of renal trauma, as even minor injuries can cause significant bleeding, while severe injuries may result in little or no visible blood. Renal trauma should be evaluated through imaging and clinical assessment.

5. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.
