1. Which vitamin is crucial for collagen synthesis and wound healing?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin E
- D. Vitamin K
Correct answer: A
Rationale: The correct answer is Vitamin C. Vitamin C is crucial for collagen synthesis, a process important for wound healing. Collagen is a key protein that helps in wound repair and tissue strength. Vitamin D is primarily known for its role in calcium absorption and bone health, not directly related to collagen synthesis. Vitamin E is an antioxidant that helps protect cells from damage but is not directly involved in collagen synthesis. Vitamin K is essential for blood clotting but does not play a major role in collagen synthesis for wound healing.
2. A nurse is providing discharge teaching to a client who has a new prescription for clopidogrel. Which of the following instructions should the nurse include?
- A. Avoid eating foods that are high in fat.
- B. Monitor for black, tarry stools while taking this medication.
- C. Avoid taking this medication with grapefruit juice.
- D. Take this medication on an empty stomach.
Correct answer: B
Rationale: The correct instruction for the nurse to include is to advise the client to monitor for black, tarry stools while taking clopidogrel. This is important because it helps detect gastrointestinal bleeding, a potential side effect of the medication. Choice A is incorrect as there is no specific requirement to avoid foods high in fat while taking clopidogrel. Choice C is incorrect as grapefruit juice interaction is not a concern with clopidogrel. Choice D is incorrect as clopidogrel can be taken with or without food.
3. How would protein deficiency likely affect dental tissues?
- A. Decreased resistance to dental caries
- B. Increased tooth size
- C. Delayed tooth development
- D. Increased enamel mineralization
Correct answer: C
Rationale: Protein deficiency can lead to delayed tooth development as the body may not have enough resources to form teeth properly. This delay can make the teeth more susceptible to dental issues due to incomplete formation. Choices A, B, and D are incorrect. Decreased resistance to dental caries is more related to factors like poor oral hygiene and sugary diets, increased tooth size is not a common effect of protein deficiency on dental tissues, and increased enamel mineralization is not typically associated with protein deficiency.
4. A nurse is planning care for a client who has tuberculosis. Which of the following actions should the nurse take to prevent the transmission of the disease?
- A. Place the client in droplet isolation.
- B. Place the client in airborne isolation.
- C. Wear a surgical mask when providing care to the client.
- D. Keep the client's door closed at all times.
Correct answer: B
Rationale: The correct answer is B: 'Place the client in airborne isolation.' Tuberculosis is an airborne disease transmitted through droplet nuclei. Placing the client in airborne isolation helps prevent the spread of the disease to others. Choice A, placing the client in droplet isolation, is incorrect because tuberculosis is not transmitted through large droplets. Choice C, wearing a surgical mask when providing care to the client, is not sufficient as airborne precautions are necessary. Choice D, keeping the client's door closed at all times, does not directly address the prevention of disease transmission in this case.
5. What condition is characterized by the inflammation of the heart's outer lining, often causing chest pain and other symptoms?
- A. Pericarditis
- B. Endocarditis
- C. Myocarditis
- D. Valvular heart disease
Correct answer: A
Rationale: Pericarditis is the correct answer because it is the inflammation of the pericardium, the outer lining of the heart. This condition commonly presents with symptoms like chest pain. Endocarditis (choice B) is the inflammation of the inner lining of the heart chambers and valves. Myocarditis (choice C) is the inflammation of the heart muscle itself. Valvular heart disease (choice D) refers to various conditions affecting the heart valves, not specifically the outer lining of the heart.
