1. Which organ absorbs water and vitamin K and may be affected by ulcerative colitis?
- A. Stomach
- B. Pancreas
- C. Large intestine
- D. Small intestine
Correct answer: C
Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.
2. Which of the following groups of vitamins are fat-soluble?
- A. vitamins B and C
- B. vitamins A and C
- C. vitamins B, E, K, D
- D. vitamins A, E, K, D
Correct answer: D
Rationale: The correct answer is D: vitamins A, E, K, and D. Fat-soluble vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamins B and C are water-soluble vitamins and are not stored in the body; any excess amounts are usually excreted in the urine. Therefore, choices A, B, and C are incorrect.
3. What is the rationale in the use of bag technique during home visits?
- A. It helps render effective nursing care to clients or other members of the family
- B. It saves time and effort of the nurse in the performance of nursing procedures
- C. It should minimize or prevent the spread of infection from individuals to families
- D. It should not overshadow concerns for the patient
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
4. The nurse understands that one of these factors contributes to constipation:
- A. excessive exercise
- B. high fiber diet
- C. no regular time for defecation daily
- D. prolonged use of laxatives
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
5. Intrinsic factor from the stomach is needed for the absorption of which vitamin?
- A. vitamin B12
- B. folate
- C. niacin
- D. vitamin B6
Correct answer: A
Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.
