Which of the following are liver waste products?
- A. bilirubin
- B. bile salts
- C. cholesterol
- D. electrolytes
Correct Answer: A
Rationale: The correct answer is A: bilirubin. Bilirubin is a waste product produced during the breakdown of red blood cells in the liver. It is excreted in bile and gives feces its brown color. Bile salts aid in digestion, cholesterol is a lipid used for various functions, and electrolytes are essential for bodily functions but are not liver waste products. Therefore, bilirubin is the only true liver waste product in this list.

What should the nurse admitting a patient with acute diverticulitis plan for initial care?
- A. Administer IV fluids.
- B. Prepare for colonoscopy.
- C. Encourage a high-fiber diet.
- D. Give stool softeners and enemas.
Correct Answer: A
Rationale: The correct answer is A: Administer IV fluids. Initial care for acute diverticulitis involves IV fluids to maintain hydration and electrolyte balance, as patients often have nausea, vomiting, and decreased oral intake. IV fluids help prevent dehydration and support the body during the acute phase of the condition. Options B, C, and D are incorrect. Colonoscopy is contraindicated during acute diverticulitis due to the risk of perforation. High-fiber diet and stool softeners/enemas are not recommended initially as they can worsen symptoms and increase the risk of complications.
A client with proctitis needs a rectal suppository. A senior nursing student assigned to this client tells you that she is afraid to insert the suppository because she has never done it before. What is the most appropriate action in supervising this student?
- A. You give the medication and report the student to the instructor.
- B. Ask the student to leave the clinical area for being unprepared.
- C. Reassign the client to an LPN/LVN.
- D. Show the student how to insert the suppository and talk to the instructor.
Correct Answer: D
Rationale: Correct Answer: D
Rationale:
1. Supervising students is part of the nursing role.
2. As a tutor, your responsibility is to guide and teach students.
3. Showing the student how to insert the suppository will help build their skills and confidence.
4. Talking to the instructor ensures proper supervision and support for the student's learning.
5. Reporting or dismissing the student is not constructive and goes against the principles of education and mentorship.
Which of the following ligaments attaches the liver to the anterior abdominal wall?
- A. coronary ligament
- B. falciform ligament
- C. quadrate ligament
- D. caudate ligament
Correct Answer: B
Rationale: The correct answer is B: falciform ligament. The falciform ligament attaches the liver to the anterior abdominal wall and separates the right and left lobes of the liver. It is a broad, thin ligament that resembles a sickle. The other choices are incorrect because:
A: The coronary ligament attaches the liver to the diaphragm, not the abdominal wall.
C: The quadrate ligament attaches the liver to the gallbladder and the lesser curvature of the stomach.
D: The caudate ligament attaches the liver to the diaphragm and is not directly related to the abdominal wall attachment.
The nurse caring for an 80-year-old woman who is undergoing extensive bowel preparation for a colonoscopy. The nurse should most closely monitor the patient for which potential complication?
- A. Diarrhea
- B. Metabolic acidosis
- C. Fatigue
- D. Dyspnea
Correct Answer: B
Rationale: The correct answer is B: Metabolic acidosis. During bowel preparation for a colonoscopy, the patient may experience fluid and electrolyte imbalances, leading to metabolic acidosis. The nurse should closely monitor for signs such as confusion, weakness, and increased respiratory rate. Diarrhea (choice A) is expected during bowel preparation but does not directly lead to metabolic acidosis. Fatigue (choice C) and dyspnea (choice D) are less likely complications of bowel preparation and do not directly relate to metabolic acidosis.
A patient receives atropine, an anticholinergic drug, in preparation for surgery. The nurse expects this drug to affect the GI tract by doing what?
- A. Increasing gastric emptying
- B. Relaxing pyloric and ileocecal sphincters
- C. Decreasing secretions and peristaltic action
- D. Stimulating the nervous system of the GI tract
Correct Answer: C
Rationale: The correct answer is C: Decreasing secretions and peristaltic action. Atropine, as an anticholinergic drug, inhibits the action of acetylcholine, leading to decreased secretions and peristaltic movement in the GI tract. This results in reduced motility and secretion production.
A: Increasing gastric emptying - This is incorrect because atropine actually slows down gastric emptying by reducing peristaltic action.
B: Relaxing pyloric and ileocecal sphincters - This is incorrect because atropine does not directly relax these sphincters.
D: Stimulating the nervous system of the GI tract - This is incorrect because atropine inhibits the parasympathetic nervous system, leading to decreased GI tract activity.
