Physical Exam Cardiovascular System
1. Which medication is used to prevent blood clots by thinning the blood, reducing the risk of stroke and heart attack?
- A. Anticoagulant
- B. ACE inhibitor
- C. Beta-blocker
- D. Calcium channel blocker
Correct answer: A
Rationale: The correct answer is 'Anticoagulant.' Anticoagulants are medications specifically designed to prevent blood clots by thinning the blood, which effectively reduces the risk of stroke, heart attack, and other cardiovascular events. Choices B, C, and D, which are ACE inhibitors, beta-blockers, and calcium channel blockers, respectively, do not have the primary mechanism of action to prevent blood clot formation. ACE inhibitors, beta-blockers, and calcium channel blockers are commonly used for managing hypertension and other cardiovascular conditions by different mechanisms of action.
2. A patient is admitted with an air leak in a chest tube system. What action should the nurse take?
- A. Tighten the connections of the chest tube system
- B. Continue monitoring the patient
- C. Replace the chest tube system
- D. Clamp the chest tube
Correct answer: A
Rationale: When caring for a patient with an air leak in the chest tube system, the nurse should tighten the connections of the chest tube system. This action can help resolve the air leak by ensuring there are no loose connections or leaks in the system. Continuing to monitor the patient (Choice B) is important, but addressing the air leak is a priority. Replacing the chest tube system (Choice C) may not be necessary if tightening the connections resolves the issue. Clamping the chest tube (Choice D) is not appropriate as it can lead to tension pneumothorax.
3. What does ethnography refer to?
- A. A detailed description of a single culture or context
- B. Corrupted by original sin
- C. The product of evolution
- D. A blank slate
Correct answer: A
Rationale: Ethnography refers to a detailed description of a single culture or context. It involves the systematic study and recording of human cultures, including customs, behaviors, and social structures. Choice B, 'Corrupted by original sin,' is incorrect as it does not relate to ethnography. Choice C, 'The product of evolution,' is incorrect as it does not define ethnography. Choice D, 'A blank slate,' is incorrect as it does not describe the practice of ethnography.
4. A client with diabetes mellitus is being taught about foot care by a nurse. What statement indicates understanding?
- A. I will soak my feet in hot water every day
- B. I will wear cotton socks at all times
- C. I will cut my toenails in a rounded shape
- D. I will apply lotion between my toes after bathing
Correct answer: B
Rationale: The correct answer is B. Wearing cotton socks is essential for clients with diabetes as it helps protect the feet and reduces the risk of skin breakdown. Choice A is incorrect because soaking feet in hot water can lead to burns or skin damage. Choice C is incorrect as clients with diabetes should cut their toenails straight across to prevent ingrown toenails. Choice D is incorrect as applying lotion between the toes can create a moist environment that may increase the risk of fungal infections.
5. Although a balanced diet is essential for tissue healing and repair, which of the following should the dental hygienist identify as the nutrient of highest priority for a patient with gingivitis or periodontal disease?
- A. Carbohydrates
- B. Vitamin C
- C. Vitamin D
- D. Monosaccharides
Correct answer: B
Rationale: Vitamin C is crucial for collagen production and connective tissue repair, making it a key nutrient for healing gingival tissues in patients with gingivitis or periodontal disease. Carbohydrates are a source of energy and not directly related to tissue repair. Vitamin D is important for bone health but is not the highest priority for gingival tissue healing. Monosaccharides are simple sugars and not as essential for tissue repair as Vitamin C.
