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: Large intestine
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 laws govern nursing practice?
- A. Statutory laws
- B. Common law
- C. Administrative laws
- D. Constitutional laws
Correct answer: A
Rationale: Statutory laws are laws created by legislative bodies, such as state legislatures. In the context of nursing practice, statutory laws govern areas like licensure requirements, scope of practice, and professional standards. Common law, choice B, is based on court decisions and precedents, not specifically related to nursing practice. Administrative laws, choice C, deal with regulations set by administrative agencies rather than governing nursing practice directly. Constitutional laws, choice D, pertain to the fundamental principles outlined in a country's constitution and are not specific to regulating nursing practice.
3. Which vitamin deficiency is commonly associated with prolonged antibiotic use?
- A. Vitamin A
- B. Vitamin B6
- C. Vitamin C
- D. Vitamin K
Correct answer: D
Rationale: The correct answer is Vitamin K. Prolonged antibiotic use can disrupt the gut flora, which is responsible for synthesizing Vitamin K. This disruption can lead to a Vitamin K deficiency and an increased risk of bleeding. Vitamin A, B6, and C deficiencies are not typically associated with prolonged antibiotic use.
4. When providing mouth care to an unconscious client, what is the best position for the client?
- A. Fowler’s position
- B. Side-lying
- C. Supine
- D. Trendelenburg
Correct answer: B
Rationale: The best position for an unconscious client when providing mouth care is the side-lying position. This position helps prevent aspiration by allowing fluids to drain out of the mouth easily, reducing the risk of choking or aspiration pneumonia. Placing the client in a side-lying position also promotes comfort and safety during the procedure. The other options are not ideal for mouth care in an unconscious client: Fowler’s position may increase the risk of aspiration, the supine position can lead to aspiration as well, and Trendelenburg position is not recommended due to potential adverse effects on blood circulation and increased intracranial pressure.
5. The nurse assesses a patient with pernicious anemia. Which assessment finding would the nurse expect?
- A. Yellow-tinged sclerae
- B. Shiny, smooth tongue
- C. Numbness of the extremities
- D. Gum bleeding and tenderness
Correct answer: C
Rationale: The correct answer is C: Numbness of the extremities. Numbness of the extremities is a common finding in patients with pernicious anemia, which is caused by cobalamin (vitamin B12) deficiency. This deficiency affects the peripheral nervous system, leading to neurological symptoms like numbness and tingling in the extremities. Choices A, B, and D are incorrect: Yellow-tinged sclerae is more indicative of jaundice or liver dysfunction, a shiny smooth tongue is seen in conditions like glossitis, and gum bleeding and tenderness are associated with periodontal disease or vitamin C deficiency, not pernicious anemia.
