1. Can bacterial plaque metabolize sucrose, lactose, and fructose? Is fructose, also known as levulose and found naturally in honey, less cariogenic than sucrose and lactose?
- A. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
- B. No, bacterial plaque cannot metabolize these sugars, and fructose is not less cariogenic.
- C. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
- D. No, bacterial plaque cannot metabolize these sugars, but yes, fructose is less cariogenic.
Correct answer: A
Rationale: The first statement is correct as bacterial plaque can indeed metabolize sucrose, lactose, and fructose. However, the second statement is inaccurate. Fructose, despite being found naturally in honey and known also as levulose, is not less cariogenic than either sucrose or lactose. This means that its consumption does not result in fewer cavities or tooth decay. Therefore, the correct answer is that bacterial plaque can metabolize these sugars, but fructose is not less cariogenic. Choices B, C, and D are incorrect because they either wrongly assert that bacterial plaque cannot metabolize these sugars or wrongly claim that fructose is less cariogenic.
2. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What is the expected therapeutic effect of this medication?
- A. Decreased urinary frequency and urgency
- B. Decreased blood pressure
- C. Increased urinary output
- D. Increased hair growth
Correct answer: A
Rationale: The correct answer is A: Decreased urinary frequency and urgency. Finasteride is used to reduce the size of the prostate gland in patients with BPH, which helps alleviate symptoms such as urinary frequency and urgency. Choice B, decreased blood pressure, is incorrect because finasteride is not indicated for lowering blood pressure. Choice C, increased urinary output, is incorrect as finasteride does not typically increase urine production. Choice D, increased hair growth, is incorrect as the primary use of finasteride is not for promoting hair growth but rather for treating BPH.
3. A patient is receiving radiation therapy. Which of the following skin care instructions should the nurse provide?
- A. Apply a heating pad to the radiation site.
- B. Use scented lotions to moisturize the skin.
- C. Keep the radiation site covered with a bandage.
- D. Wear loose clothing over the radiation site.
Correct answer: D
Rationale: Correct Answer: The nurse should instruct the patient to wear loose clothing over the radiation site. This helps prevent skin irritation and promotes healing by reducing friction and irritation on the treated area.\nChoice A is incorrect because applying a heating pad can further irritate the skin that is already sensitive due to radiation therapy.\nChoice B is incorrect because scented lotions may contain ingredients that could further irritate the skin.\nChoice C is incorrect because covering the radiation site with a bandage can trap moisture and lead to skin breakdown, increasing the risk of infection.
4. A client with angina asks about obtaining a prescription for sildenafil to treat erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?
- A. Aspirin
- B. Isosorbide
- C. Clopidogrel
- D. Atorvastatin
Correct answer: B
Rationale: Isosorbide is an organic nitrate used to manage angina. Concurrent use of sildenafil with organic nitrates, like isosorbide, is contraindicated due to the risk of fatal hypotension. It is essential for clients to avoid taking nitrate medications within 24 hours of using isosorbide to prevent serious complications.
5. The process of ________ is used to increase the probability that a behavior will occur.
- A. operant conditioning
- B. reinforcement
- C. classical conditioning
- D. punishment
Correct answer: B
Rationale: The correct answer is reinforcement. Reinforcement involves providing a consequence that increases the likelihood of a behavior being repeated. Operant conditioning (Choice A) refers to learning through consequences for behavior, which includes reinforcement and punishment. Classical conditioning (Choice C) involves forming associations between stimuli and involuntary responses. Punishment (Choice D) involves providing a consequence that decreases the likelihood of a behavior being repeated. In this context, the question specifically asks about a process that increases the probability of a behavior occurring, aligning with the concept of reinforcement.
