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. A child diagnosed with aplastic anemia is admitted to the hospital. The parents ask the nurse what aplastic anemia is. Which response by the nurse is accurate?

• A. Aplastic anemia causes a proliferation of white blood cells.
• B. Aplastic anemia is characterized by abnormally shaped red blood cells.
• C. Aplastic anemia is caused by the bone marrow producing inadequate cells.
• D. Aplastic anemia is a disorder that occurs after a viral illness.

Correct answer: C

Rationale: Aplastic anemia is a condition where the bone marrow fails to produce sufficient red blood cells, white blood cells, and platelets, leading to pancytopenia. This can result in fatigue, infections, and bleeding tendencies. It is not characterized by abnormal red blood cell shapes, but rather by a reduction in the production of blood cells. Therefore, the accurate response is that aplastic anemia is caused by the bone marrow producing inadequate cells. Choices A and B are incorrect as aplastic anemia does not cause a proliferation of white blood cells or involve abnormally shaped red blood cells. Choice D is incorrect as aplastic anemia is not typically a disorder that occurs after a viral illness.

3. The nurse is caring for a child with Neuroblastoma. Where is the tumor most commonly located?

• A. Bone
• B. Kidneys
• C. Cortex
• D. Abdomen

Correct answer: D

Rationale: Neuroblastoma is a cancer that commonly originates in the adrenal glands located in the abdomen. It can also occur in nerve tissues along the spine, but it is most frequently found in the abdominal region. Therefore, the correct answer is D. Choices A, B, and C are incorrect as Neuroblastoma typically arises from neural crest cells in the adrenal glands or sympathetic ganglia, not in the bones, kidneys, or cortex.

4. The school nurse is explaining to older school children that obesity increases the risk for which disorders? (Select all that apply.)

• A. Asthma
• B. Hypertension
• C. Dyslipidemia
• D. All of the above

Correct answer: D

Rationale: Obesity increases the risk for conditions like asthma, hypertension, dyslipidemia, and altered glucose metabolism, but not typically irritable bowel disease.

5. The nurse is caring for a child with acute postinfectious glomerulonephritis. Which of the following best describes the pathophysiology of acute postinfectious glomerulonephritis?

• A. Occurs after a urinary tract infection
• B. Occurs after a streptococcal infection
• C. Associated with renal vascular disorders
• D. Is caused by E. coli

Correct answer: B

Rationale: The correct answer is B: 'Occurs after a streptococcal infection.' Acute postinfectious glomerulonephritis often occurs after an infection with certain strains of streptococcus bacteria, specifically group A streptococcus. The body’s immune response to the infection leads to inflammation and damage in the kidneys. Choices A, C, and D are incorrect because acute postinfectious glomerulonephritis is primarily associated with streptococcal infections, not urinary tract infections, renal vascular disorders, or E. coli.
