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.

A patient calls the clinic to report a new onset of severe diarrheWhat should the nurse anticipate that the patient will need to do?
- A. Collect a stool specimen.
- B. Prepare for colonoscopy.
- C. Schedule a barium enema.
- D. Have blood cultures drawn.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. Stool specimen collection helps identify the cause of diarrhea (e.g., infection).
2. It assists in determining appropriate treatment.
3. It helps rule out serious conditions.
4. Colonoscopy (B) and barium enema (C) are invasive procedures not typically indicated for acute diarrhea.
5. Blood cultures (D) are not the first-line investigation for diarrhea without systemic signs of infection.
A patient with cirrhosis that is refractory to other treatments for esophageal varices undergoes a portacaval shunt. As a result of this procedure, what should the nurse expect the patient to experience?
- A. An improved survival rate
- B. Decreased serum ammonia levels
- C. Improved metabolism of nutrients
- D. Improved hemodynamic function and renal perfusion
Correct Answer: D
Rationale: The correct answer is D: Improved hemodynamic function and renal perfusion. A portacaval shunt is a surgical procedure that diverts blood flow from the portal vein directly into the vena cava, reducing portal hypertension. This leads to improved hemodynamic function by decreasing pressure in the portal system, which can improve renal perfusion. Choices A, B, and C are incorrect because a portacaval shunt may not necessarily improve survival rate, decrease serum ammonia levels, or improve metabolism of nutrients.
What is the function of bile salts?
- A. emulsifying fats
- B. breaking down carbohydrates
- C. activating pepsin
- D. digesting proteins
Correct Answer: A
Rationale: The correct answer is A: emulsifying fats. Bile salts help emulsify fats by breaking them into smaller droplets, increasing the surface area for enzymes to act upon during digestion. This aids in the absorption of fats in the small intestine. Choices B, C, and D are incorrect because bile salts do not have a direct role in breaking down carbohydrates (choice B), activating pepsin (choice C), or digesting proteins (choice D). These functions are carried out by other digestive enzymes in the gastrointestinal tract.
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.
Priority Decision: A postoperative patient has a nursing diagnosis of pain related to effects of medication and decreased GI motility as evidenced by abdominal pain and distention and inability to pass flatus. Which nursing intervention is most appropriate for this patient?
- A. Ambulate the patient more frequently.
- B. Assess the abdomen for bowel sounds.
- C. Place the patient in high Fowler's position.
- D. Withhold opioids because they decrease bowel motility.
Correct Answer: A
Rationale: Rationale for Correct Answer (A): Ambulating the patient more frequently helps to stimulate GI motility, reduce abdominal distention, and promote passage of flatus. Movement aids in peristalsis, which can alleviate postoperative GI issues.
Summary of Incorrect Choices:
B: Assessing bowel sounds is important but does not directly address the issue of stimulating GI motility or addressing the patient's pain and distention.
C: Placing the patient in a high Fowler's position may improve respiratory function but does not specifically target GI motility or pain relief.
D: Withholding opioids may be necessary in some cases, but pain management is crucial for postoperative care. There are other ways to address decreased GI motility without completely withholding pain medications.
