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 planning a treatment and prevention program of chronic fecal incontinence for an elderly client, which intervention should you try first?
- A. Administer a glycerin suppository 15 minutes before evacuation time.
- B. Insert a rectal tube at specified intervals each day.
- C. Assist the client to the bedpan or toilet 30 minutes after meals.
- D. Use incontinence briefs or adult-sized diapers.
Correct Answer: C
Rationale: The correct answer is C: Assist the client to the bedpan or toilet 30 minutes after meals. This intervention is appropriate as it aligns with the natural physiological process of bowel movements after meals, increasing the likelihood of successful evacuation. This timing can help establish a routine and promote regular bowel movements, potentially reducing episodes of fecal incontinence.
Choice A is incorrect because administering a glycerin suppository may not address the underlying cause of fecal incontinence and may not promote regular bowel movements. Choice B is incorrect as inserting a rectal tube is an invasive intervention that should only be considered after less invasive methods have been exhausted. Choice D is incorrect as using incontinence briefs or adult-sized diapers only manages the symptoms without addressing the root cause or promoting bowel regularity.
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.
What causes the systemic effects of viral hepatitis?
- A. Cholestasis
- B. Impaired portal circulation
- C. Toxins produced by the infected liver
- D. Activation of the complement system by antigen-antibody complexes
Correct Answer: D
Rationale: Step-by-step rationale for why choice D is correct: Activation of the complement system by antigen-antibody complexes leads to systemic effects in viral hepatitis. This process triggers inflammation, tissue damage, and immune responses that contribute to the systemic effects seen in viral hepatitis. The other choices (A, B, and C) do not directly cause systemic effects in viral hepatitis. Cholestasis and impaired portal circulation are more localized effects, while toxins produced by the infected liver may contribute to liver damage but not necessarily systemic effects.
Contractions that mix material in the small intestine are called
- A. peristalsis.
- B. deglutition.
- C. mass movements
- D. segmental contractions.
Correct Answer: D
Rationale: The correct answer is D: segmental contractions. Segmental contractions mix material in the small intestine by contracting and relaxing specific segments of the intestine to mix and move the contents. This process helps with digestion and nutrient absorption.
A: Peristalsis refers to the wave-like muscle contractions that propel food through the digestive system, not mixing.
B: Deglutition is the process of swallowing food, not mixing it in the small intestine.
C: Mass movements are large contractions that move material through the large intestine, not the small intestine where mixing occurs.
Histamine stimulates the ______ cells to release ______.
- A. parietal; intrinsic factor
- B. chief; pepsinogen
- C. parietal; HCl
- D. mucous neck; mucus
Correct Answer: C
Rationale: Histamine stimulates the parietal cells in the stomach lining to release hydrochloric acid (HCl). This process plays a crucial role in the digestion of food. Parietal cells are responsible for producing stomach acid, which helps break down food and kill bacteria. Choice A is incorrect because intrinsic factor is not released by parietal cells in response to histamine. Choice B is incorrect because pepsinogen is released by chief cells, not parietal cells. Choice D is incorrect because mucous neck cells secrete mucus to protect the stomach lining, but they are not directly stimulated by histamine to release mucus.
