1. Digestible carbs are absorbed as ___ through the small intestinal wall and are delivered to the liver, which releases ___ into the bloodstream.
- A. glucose
- B. monosaccharides
- C. galactose
- D. disaccharides
Correct answer: B
Rationale: Digestible carbohydrates are absorbed as monosaccharides (simple sugars) like glucose, which the liver can release into the bloodstream for energy.
2. Which is NOT a characteristic or function of lipids?
- A. Involved in energy metabolism and storage
- B. Provide insulation and protection
- C. Act as hormones that regulate the body
- D. Are hydrophilic
Correct answer: D
Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.
3. Which vitamin is essential for proper blood clotting?
- A. Vitamin A
- B. Vitamin E
- C. Vitamin K
- D. Vitamin C
Correct answer: C
Rationale: Vitamin K is vital for the synthesis of clotting factors, which are necessary for proper blood clotting. Vitamin A (Choice A) is important for vision and skin health, not blood clotting. Vitamin E (Choice B) is an antioxidant that helps protect cells from damage but is not directly involved in blood clotting. Vitamin C (Choice D) is essential for collagen synthesis and a healthy immune system, but it does not play a direct role in blood clotting.
4. Which systolic blood pressure measurement is classified as prehypertension?
- A. 106 mmHg
- B. 119 mmHg
- C. 130 mmHg
- D. 141 mmHg
Correct answer: B
Rationale: According to the blood pressure classification, a systolic blood pressure between 120-139 mmHg is considered prehypertension. This range indicates an increased risk for developing hypertension if not managed appropriately. Therefore, a systolic blood pressure of 119 mmHg falls into the prehypertension category. A systolic pressure of 106 mmHg is within the normal range, while 130 mmHg and above would be classified as stage 1 and stage 2 hypertension respectively, not prehypertension.
5. The IVP reveals that Fe has small renal calculus that can be passed out spontaneously. To increase the chance of passing the stones, you instructed her to force fluids and do which of the following?
- A. Balanced diet C. Strain all urine
- B. Ambulate more D. Bed rest
- C.
- D.
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
