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.

- A. Reduce proteinuria
- B. Lower blood pressure
- C. Increase urine output
- D. Prevent infections
Correct Answer: A

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.

- A. Cyanosis
- B. Bradycardia
- C. Absent breath sounds

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.
After surgery yesterday for gastroesophageal reflux, the nurse finds that the infant has somehow removed the nasogastric (NG) tube. What nursing action is most appropriate to perform at this time?
- A. Notify the healthcare provider.
- B. Insert a new NG tube for feedings.
- C. Replace the NG tube to maintain gastric decompression.
- D. Leave the NG tube out as it may have been in long enough.
Correct Answer: A
Rationale: The most appropriate action for the nurse to take in this situation is to notify the healthcare provider immediately. This is important as the removal of the NG tube can disrupt postoperative care, especially in terms of maintaining gastric decompression. Inserting a new NG tube without practitioner direction can be unsafe and is not within the nurse's scope of practice. Similarly, replacing the NG tube or leaving it out should be decided by the healthcare provider to ensure the infant's safety and appropriate postoperative care.
The nurse is assisting a child with celiac disease to select foods from a menu. What foods should the nurse suggest?
- A. Hamburger patty with no bun
- B. Spaghetti with marinara sauce
- C. Corn on the cob with butter
- D. Rice cakes with hummus
Correct Answer: C
Rationale: The correct answer is C: Corn on the cob with butter. Corn is a gluten-free option suitable for children with celiac disease. Choice A is incorrect because the bun contains gluten, so suggesting a hamburger patty without the bun is a better option. Choice B is not ideal as spaghetti often contains gluten, but spaghetti with marinara sauce could be a safer choice if the spaghetti is gluten-free. Choice D, rice cakes with hummus, is a gluten-free alternative, but corn on the cob is a more straightforward and common choice for children.
