1. What is a major constituent of cell membranes?
- A. cholesterol
- B. phospholipid
- C. saturated
- D. triglyceride
Correct answer: B
Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.
2. Mang Carlos has a standing DNR order. He then suddenly stopped breathing and you are at his bedside. You would:
- A. Give extraordinary measures to save Mang Carlos
- B. Stay with Mang Carlos and Do nothing
- C. Call the physician
- D. Activate Code Blue
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
3. Which factor has been shown to increase the risk of development of atherosclerosis?
- A. Menopause
- B. Age older than 35
- C. Increased levels of arachidonic acid
- D. Elevated HDL cholesterol
Correct answer: A
Rationale: The correct answer is A: Menopause. Menopause is associated with an increased risk of atherosclerosis due to hormonal changes that affect lipid profiles and vascular health. Conversely, B: Age older than 35 is not necessarily a risk factor for atherosclerosis on its own, though atherosclerosis risk does generally increase with age. C: Increased levels of arachidonic acid is not specifically linked to atherosclerosis; it's a fatty acid that can be both beneficial and harmful to health depending on its metabolic pathway. D: Elevated HDL cholesterol is actually beneficial rather than harmful because HDL cholesterol is known as 'good' cholesterol that helps to reduce the risk of heart disease and atherosclerosis.
4. A nurse is preparing to teach a group of clients about vitamins and minerals. The nurse should include in the teaching that which of the following minerals is necessary for the transmission of nerve impulses?
- A. Phosphorus
- B. Calcium
- C. Chloride
- D. Zinc
Correct answer: B
Rationale: Corrected Question: A nurse is preparing to teach a group of clients about vitamins and minerals. The nurse should include in the teaching that which of the following minerals is necessary for the transmission of nerve impulses? Correct Answer: Calcium Rationale: Calcium is crucial for nerve transmission, muscle contraction, and blood clotting. It plays a vital role in the proper functioning of the nervous system. Phosphorus is important for bone health and energy metabolism, not nerve impulse transmission. Chloride is an electrolyte important for fluid balance but not directly involved in nerve impulse transmission. Zinc is essential for immune function and wound healing but not specifically required for nerve impulse transmission.
5. A healthcare provider is evaluating a client who reports paresthesia of the hands and feet. The provider should identify this manifestation as an indication of which of the following dietary deficiencies?
- A. Iron
- B. Riboflavin
- C. Vitamin C
- D. Vitamin B12
Correct answer: D
Rationale: Correct! Vitamin B12 deficiency can lead to neurological symptoms, including paresthesia (tingling or numbness) of the hands and feet, due to its role in nerve health. Iron deficiency is more commonly associated with anemia symptoms like fatigue and pallor. Riboflavin deficiency can cause mouth and skin changes. Vitamin C deficiency is linked to scurvy symptoms like bleeding gums and easy bruising.
