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 statements about Z-Track technique is false?
- A. Z-Track injections prevent irritation of the subcutaneous tissues
- B. The technique involves creating a Zig-Zag like pattern of medication
- C. It forces the medication to be contained in the subcutaneous tissues
- D. It is used when administering Parenteral Iron
Correct answer: B
Rationale: The Z-Track technique is aimed at preventing medication leakage into the surrounding tissues by sealing the medication in the muscle, not by creating a Zig-Zag pattern. Choice A is correct as Z-Track injections help prevent irritation. Choice C is correct as it accurately describes how the technique works. Choice D is also correct as the Z-Track technique is commonly used when administering Parenteral Iron to prevent staining and irritation of the surrounding tissues.
3. According to the dietary reference intakes, what percentage of your daily calorie intake should ideally come from carbohydrates?
- A. 10-35%
- B. 20-35%
- C. 40-50%
- D. 45-65%
Correct answer: D
Rationale: Carbohydrates should ideally make up 45-65% of your total daily caloric intake, according to the Dietary Reference Intakes (DRIs). This range provides the necessary energy for bodily functions and activities. Choices A, B, and C are incorrect because they fall outside the recommended range for carbohydrate intake based on the DRIs.
4. A nurse is caring for a client who has cancer and is receiving total parenteral nutrition (TPN). Which of the following lab values indicates the treatment is effective?
- A. Hct 43%
- B. WBC 8,000/uL
- C. Albumin 4.2 g/dL
- D. Calcium 9.4 mg/dL
Correct answer: C
Rationale: The correct answer is Albumin 4.2 g/dL. Albumin is a protein produced by the liver and is a key indicator of nutritional status. In a client receiving total parenteral nutrition (TPN), an increase in albumin level indicates that the treatment is effective in providing adequate nutrition support. Hct (hematocrit), WBC (white blood cell count), and calcium levels are not direct indicators of the effectiveness of TPN in this context.
5. Select all that apply. To lower LDL levels, you should:
- A. consume minimal amounts of hydrogenated and saturated fats
- B. consume more insoluble fibers than soluble fibers
- C. consume alcohol in moderate levels
- D. engage in regular physical activity
Correct answer: A
Rationale: To lower LDL levels, reducing intake of hydrogenated (trans) and saturated fats is crucial, as these types of fats can raise LDL cholesterol in the blood. Choice B is incorrect because both soluble and insoluble fibers can help lower LDL levels. Choice C is incorrect as excessive alcohol consumption can lead to increased LDL levels. Choice D, engaging in regular physical activity, can help raise HDL (good) cholesterol levels but is not directly related to lowering LDL levels.
