Amylase could be found in all of these areas except which one?
- A. mouth
- B. stomach
- C. duodenum
- D. pancreas
Correct Answer: B
Rationale: The correct answer is B (stomach) because amylase is an enzyme that breaks down carbohydrates, and it is primarily found in the mouth and the small intestine (duodenum and pancreas). In the mouth, salivary amylase begins the digestion of starches. In the small intestine, pancreatic amylase continues this process. The stomach, however, is not a site for amylase secretion but rather secretes pepsin for protein digestion. Therefore, amylase is not found in the stomach. Choices A, C, and D are incorrect because amylase is indeed present in the mouth, duodenum, and pancreas, respectively.

A nurse is caring for a client who reports having chronic constipation. Which of the following herbal supplements should the nurse recommend?
- A. Ginseng
- B. Coenzyme Q-10
- C. Cranberry juice
- D. Flaxseed
Correct Answer: D
Rationale: The correct answer is D: Flaxseed. Flaxseed is rich in fiber, which helps promote bowel regularity and relieve constipation. The insoluble fiber in flaxseed adds bulk to stool, making it easier to pass. Ginseng (A) is not typically used for constipation. Coenzyme Q-10 (B) is not known to alleviate constipation. Cranberry juice (C) is more commonly used for urinary tract health, not constipation. Flaxseed is the best choice due to its high fiber content and effectiveness in promoting regular bowel movements.
Mandy, an adolescent girl is admitted to an acute care facility with severe malnutrition. After a thorough examination, the physician diagnoses anorexia nervosa. When developing the plan of care for this client, the nurse is most likely to include which nursing diagnosis?
- A. Hopelessness
- B. Powerlessness
- C. Chronic low self-esteem
- D. Deficient knowledge
Correct Answer: C
Rationale: The correct answer is C: Chronic low self-esteem. In anorexia nervosa, individuals often have distorted body image and low self-esteem, which contributes to their disordered eating behavior. By addressing the nursing diagnosis of chronic low self-esteem, the nurse can focus on interventions to help improve the client's self-worth and body image perception.
A: Hopelessness may be present in anorexia nervosa but chronic low self-esteem is more directly related to the disorder.
B: Powerlessness is not the primary nursing diagnosis in anorexia nervosa; it may be a secondary issue.
D: Deficient knowledge is not the main nursing diagnosis in anorexia nervosa; clients generally have knowledge about their condition but struggle with self-image and self-esteem.
A nurse is caring for a client who has just returned from the PACU after a traditional cholecystectomy. In which of the following positions should the nurse place the client?
- A. Prone
- B. Semi-Fowler's
- C. Supported Sims'
- D. Dorsal recumbent
Correct Answer: B
Rationale: The correct answer is B: Semi-Fowler's position. After a traditional cholecystectomy, placing the client in a Semi-Fowler's position (head of the bed elevated at 30-45 degrees) helps promote lung expansion, improve breathing, and reduce the risk of aspiration. This position also helps with comfort and aids in preventing complications such as respiratory issues and surgical site complications.
A: Prone position is incorrect as it involves lying on the stomach and is not appropriate for a client after cholecystectomy due to the risk of putting pressure on the abdomen and surgical site.
C: Supported Sims' position is incorrect as it is typically used for rectal examinations or enemas, not for post-cholecystectomy care.
D: Dorsal recumbent position is incorrect as it involves lying on the back with knees flexed, which may not provide optimal support and comfort for a client post-cholecystectomy.
In the colon, the teniae coli are bands of ______, which contract to form ______.
- A. fat; epiploic appendages
- B. longitudinal smooth muscle; haustra
- C. skeletal muscle; haustra
- D. smooth muscle; the internal anal sphincter
Correct Answer: B
Rationale: The correct answer is B because the teniae coli are bands of longitudinal smooth muscle in the colon. These bands contract to form haustra, which are the pouches that give the colon its segmented appearance. Choice A is incorrect because fat and epiploic appendages are not involved in the contraction of the colon. Choice C is incorrect because the teniae coli are smooth muscle, not skeletal muscle. Choice D is incorrect because the internal anal sphincter is not formed by the contraction of the teniae coli.
A nurse is doing a nursing assessment on a patient with chronic constipation. What data obtained during the interview may be a factor contributing to the constipation?
- A. Taking methylcellulose (Citrucel) daily
- B. History of hemorrhoids and hypertension
- C. High dietary fiber with high fluid intake
- D. Suppressing the urge to defecate while at work
Correct Answer: D
Rationale: The correct answer is D: Suppressing the urge to defecate while at work. This behavior can lead to chronic constipation as it disrupts the natural bowel movement process. By holding in the urge to defecate, the stool can become harder and more difficult to pass, leading to constipation.
A: Taking methylcellulose daily is a form of fiber supplement that can actually help alleviate constipation by adding bulk to the stool and promoting regular bowel movements.
B: History of hemorrhoids and hypertension may be relevant to the patient's health but are not direct contributors to constipation.
C: High dietary fiber with high fluid intake is actually beneficial in preventing constipation by promoting healthy bowel movements.
