Metabolic rate is high in the following Except:
- A. Pregnancy.
- B. Sleep.
- C. Male than female of the same body surface area.
- D. Walking than resting state.
Correct Answer: B
Rationale: The correct answer is B: Sleep. During sleep, the body's metabolic rate decreases as it enters a state of rest and recovery. Pregnancy (A) requires increased energy expenditure for fetal development. Males generally have higher metabolic rates than females (C) due to higher muscle mass. Walking (D) requires more energy than resting, leading to a higher metabolic rate. In summary, sleep is the exception as it lowers metabolic rate compared to the other activities listed.

In report, the nurse learns that the patient has a transverse colostomy. What should the nurse expect when providing care for this patient?
- A. Semiliquid stools with increased fluid requirements
- B. Liquid stools in a pouch and increased fluid requirements
- C. Formed stools with a pouch, needing irrigation, but no fluid needs
- D. Semiformed stools in a pouch with the need to monitor fluid balance
Correct Answer: A
Rationale: The correct answer is A: Semiliquid stools with increased fluid requirements. A transverse colostomy is located in the upper part of the colon, where stool consistency is more liquid. This type of colostomy typically produces semiliquid stools due to the shorter transit time in the colon, leading to increased fluid requirements to prevent dehydration.
Summary of other choices:
B: Liquid stools in a pouch and increased fluid requirements - Incorrect because transverse colostomies produce semiliquid stools, not entirely liquid.
C: Formed stools with a pouch, needing irrigation, but no fluid needs - Incorrect as transverse colostomies do not produce formed stools, and fluid intake is necessary.
D: Semiformed stools in a pouch with the need to monitor fluid balance - Incorrect because transverse colostomies produce semiliquid stools, not semiformed, and increased fluid intake is needed.
The following statements are true about bile except:
- A. 25% is produced by bile duct cells
- B. The bile stored in the gall bladder contains secondary bile acids
- C. Its secretion is increased by secretin
- D. Bile pigments are needed for micelle formation
Correct Answer: D
Rationale: The correct answer is D because bile pigments are not needed for micelle formation. Micelles are formed by bile salts, which aid in the emulsification of fats. Choice A is incorrect as bile is primarily produced by the liver, not bile duct cells. Choice B is incorrect as primary bile acids are stored in the gall bladder, not secondary bile acids. Choice C is incorrect as secretin stimulates the release of pancreatic enzymes, not bile secretion.
A nurse is assessing a client who is 3 days postoperative following abdominal surgery and notes the absence of bowel sounds, abdominal distention, and the client passing no flatus. Which of the following conditions should the nurse suspect?
- A. Ulcerative colitis
- B. Cholecystitis
- C. Paralytic ileus
- D. Wound dehiscence
Correct Answer: C
Rationale: The correct answer is C: Paralytic ileus. After abdominal surgery, the bowel can temporarily stop functioning due to anesthesia, handling of the intestines, or inflammation. This leads to absent bowel sounds, distention, and no flatus passage. Ulcerative colitis (A) is a chronic inflammatory bowel disease, not related to postoperative findings. Cholecystitis (B) is inflammation of the gallbladder, typically presenting with right upper quadrant pain. Wound dehiscence (D) is the separation of surgical incision edges, not related to bowel function.
Na and other carrier ions facilitate absorption of
- A. amino acids and fructose
- B. fatty acids and glycerol
- C. fatty acids and glucose
- D. amino acids and glucose
Correct Answer: D
Rationale: The correct answer is D: amino acids and glucose. Na ions facilitate the absorption of these molecules in the small intestine through the process of co-transport with carrier proteins. Glucose and amino acids are primarily absorbed in the small intestine to be utilized by the body for energy and growth. Na ions help transport these molecules across the intestinal epithelium against their concentration gradients.
A: Amino acids and fructose - While Na ions do play a role in the absorption of amino acids, fructose is primarily absorbed through facilitated diffusion and does not require Na ions for absorption.
B: Fatty acids and glycerol - Fatty acids and glycerol are absorbed in the small intestine through a different mechanism called micelle formation and do not rely on Na ions for absorption.
C: Fatty acids and glucose - While Na ions do play a role in the absorption of glucose, fatty acids are primarily absorbed through micelle formation and do not require Na ions for absorption.
In human, the cardiac sphincter surrounds the cardiac orifice in the digestive tract. The failure of this sphincter's normal function will result in
- A. regurgation of the food into the oesophagus
- B. loss of control of defecation
- C. movement of the bolus into the trachea rather than the oesophagus
- D. rapid emptying from the stomach to the small intestine
Correct Answer: A
Rationale: The correct answer is A: regurgitation of the food into the oesophagus. The cardiac sphincter is located at the junction between the esophagus and the stomach. Its main function is to prevent the backflow of stomach contents into the esophagus. If the cardiac sphincter fails to function properly, it can lead to regurgitation, where stomach contents flow back into the esophagus, causing discomfort and potential damage to the esophageal lining.
Summary:
B: Loss of control of defecation is not related to the cardiac sphincter, as it primarily functions in the upper digestive tract.
C: Movement of the bolus into the trachea is related to swallowing reflex and epiglottis function, not the cardiac sphincter.
D: Rapid emptying from the stomach to the small intestine is controlled by the pyloric sphincter, not the cardiac sphincter.
