1. How many grams of protein per day are recommended for a person weighing 150 lbs?
- A. 120
- B. 85
- C. 187.5
- D. 54
Correct answer: D
Rationale: The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. To convert pounds to kilograms, divide the weight in pounds by 2.2. Therefore, a 150 lb person weighs approximately 68 kg (150 / 2.2 = 68). Multiplying 68 kg by 0.8 grams gives us 54 grams of protein per day. Choices A, B, and C are incorrect as they do not align with the RDA calculation based on body weight.
2. Richard is a subject of a research lead by his doctor. The nurse knows that all of the following is a correct understanding as his right as a research subject except:
- A. I can withdraw with this research even after the research has been started
- B. My confidentiality will not be compromised in this research
- C. I must choose another doctor if I withdrew from this research
- D. I can withdraw with this research before the research has been started
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.
3. _____ neutralizes stomach acid in the small intestine:
- A. saliva
- B. gastric mucus
- C. bicarbonate ions
- D. enzymes
Correct answer: C
Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.
4. Where is Vitamin E commonly found?
- A. produced by bacteria in the GI tract
- B. synthesized by the body through sunlight exposure
- C. associated with beriberi deficiency
- D. present in vegetable oils
Correct answer: D
Rationale: Vitamin E is an antioxidant commonly found in sources like vegetable oils, nuts, seeds, and green leafy vegetables. It plays a crucial role in protecting cells from damage. Choices A and B are incorrect as Vitamin E is not produced by bacteria in the GI tract nor synthesized by sunlight exposure. Choice C is incorrect as beriberi is a deficiency of Vitamin B1 (thiamine), not Vitamin E.
5. A healthcare professional has just inserted an NG tube for a client who is to start enteral tube feedings. Which of the following actions should the healthcare professional take to verify tube placement?
- A. Measure the tube length.
- B. Obtain an abdominal x-ray.
- C. Flush the tube with 20 mL of water.
- D. Auscultate the client’s lungs.
Correct answer: B
Rationale: Obtaining an abdominal x-ray is the most accurate method to verify the correct placement of an NG tube. Measuring the tube length is not a reliable method to confirm placement as it may vary among individuals. Flushing the tube with water and auscultating the client's lungs are not definitive methods to ensure proper NG tube placement.
