Nursing Elites

1. What is an appropriate screening test for hearing that the nurse can administer to a 5-year-old child?

• A. Rinne test
• B. Weber test
• C. Pure tone audiometry
• D. Eliciting the startle reflex

Correct answer: C

Rationale: Pure tone audiometry is an appropriate and effective screening test for hearing in a 5-year-old child, helping to assess the ability to hear various frequencies and volumes.

2. 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.

3. A child with acetaminophen (Tylenol) poisoning has been admitted to the emergency department. What antidote does the nurse anticipate being prescribed?

• A. Carnitine (Carnitor)
• B. Fomepizole (Antizol)
• C. Deferoxamine (Desferal)
• D. N-acetylcysteine (Mucomyst)

Correct answer: D

Rationale: N-acetylcysteine is the specific antidote for acetaminophen poisoning, working by replenishing glutathione and preventing liver damage. The other options are antidotes for different types of poisoning (e.g., Fomepizole for methanol or ethylene glycol poisoning).

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. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?

• A. Neurogenic shock
• B. Cardiogenic shock
• C. Hypovolemic shock
• D. Anaphylactic shock

Correct answer: D

Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.
