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. 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.
3. What test is used to screen for carbohydrate malabsorption?
- A. Stool pH
- B. Urine ketones
- C. C urea breath test
- D. ELISA stool assay
Correct answer: A
Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.
4. In pediatric patients, what is the primary concern with untreated vesicoureteral reflux (VUR)?
- A. Recurrent UTIs
- B. Chronic renal failure
- C. Hypertension
- D. Bladder dysfunction
Correct answer: B
Rationale: The primary concern with untreated vesicoureteral reflux (VUR) in pediatric patients is chronic renal failure. Untreated VUR can lead to this complication due to recurrent urinary tract infections and kidney damage. While recurrent UTIs (Choice A) are a common consequence of VUR, the ultimate worry is the development of chronic renal failure. Hypertension (Choice C) may occur as a result of renal damage but is not the primary concern. Bladder dysfunction (Choice D) is not the most significant consequence of untreated VUR in terms of long-term outcomes compared to chronic renal failure.
5. The mother of a 3-month-old breastfed infant asks about giving her baby water because it is summer and very warm. What should the nurse tell her?
- A. Fluids in addition to breast milk are not needed.
- B. Water should be given if the infant seems to nurse longer than usual.
- C. Clear juices are better than water to promote adequate fluid intake.
- D. Water once or twice a day will make up for losses resulting from environmental temperature.
Correct answer: A
Rationale: Breast milk provides adequate hydration, even in warm weather, so additional fluids like water are not necessary and can interfere with breastfeeding.
