1. How does tamsulosin (Flomax) primarily benefit male patients with benign prostatic hyperplasia (BPH)?
- A. Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow.
- B. Reduction in prostate size and improvement in urinary symptoms.
- C. Increase in urine flow and relief of urinary obstruction.
- D. Improvement in erectile function.
Correct answer: A
Rationale: The correct answer is A: Tamsulosin works by relaxing the muscles in the prostate and bladder neck, which helps improve urinary flow in patients with BPH. This relaxation reduces the symptoms associated with BPH, such as urinary hesitancy, urgency, and frequency. Choice B is incorrect because tamsulosin does not directly reduce the size of the prostate gland. Choice C is incorrect as while tamsulosin does improve urine flow, its primary mechanism of action is through muscle relaxation rather than directly relieving obstruction. Choice D is incorrect as tamsulosin is not indicated for improving erectile function; its main therapeutic effect is targeted towards urinary symptoms related to BPH.
2. A 30-year-old woman is taking an oral contraceptive and is concerned about the potential side effects. What should the nurse include in the patient education?
- A. Oral contraceptives can cause weight loss and increased energy levels.
- B. Oral contraceptives can cause increased appetite and weight gain.
- C. Oral contraceptives can cause headaches and breast tenderness.
- D. Oral contraceptives have no side effects.
Correct answer: C
Rationale: The correct answer is C: 'Oral contraceptives can cause headaches and breast tenderness.' It is essential for the nurse to educate the patient about common side effects of oral contraceptives, such as headaches and breast tenderness. Choices A, B, and D are incorrect. Weight loss and increased energy levels (Choice A) are not common side effects of oral contraceptives. Similarly, increased appetite and weight gain (Choice B) are not typical side effects. Finally, stating that oral contraceptives have no side effects (Choice D) is inaccurate as they can have various side effects, albeit usually mild and manageable.
3. Which of the following is a common cause of secondary hypertension?
- A. Primary aldosteronism
- B. Essential hypertension
- C. White coat hypertension
- D. Prehypertension
Correct answer: A
Rationale: Primary aldosteronism is a common cause of secondary hypertension. In primary aldosteronism, there is an overproduction of aldosterone from the adrenal glands, leading to increased sodium retention and potassium excretion, ultimately resulting in high blood pressure. Essential hypertension (Choice B) is the most common type of hypertension, but it is considered primary hypertension, not secondary. White coat hypertension (Choice C) refers to elevated blood pressure readings in a clinical setting due to anxiety but not in daily life. Prehypertension (Choice D) is a condition where blood pressure levels are elevated but not high enough to be classified as hypertension.
4. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What should the nurse include in the patient education?
- A. The medication is expected to reduce the size of the prostate, which should improve urinary symptoms over time.
- B. The medication will improve symptoms within a few days.
- C. The medication will cure BPH after treatment is complete.
- D. The medication may cause erectile dysfunction as a side effect.
Correct answer: A
Rationale: Finasteride is expected to reduce the size of the prostate, which should improve urinary symptoms over time, although the effects may take several weeks or months to become noticeable.
5. Which type of lymphocyte recognizes and eliminates virus-infected cells and cancerous cells?
- A. Neutrophils
- B. Macrophages
- C. Natural killer cells
- D. Langerhans cells
Correct answer: C
Rationale: Natural killer cells are a type of lymphocyte that plays a crucial role in recognizing and eliminating virus-infected cells and cancerous cells. Neutrophils (Choice A) are a type of white blood cell involved in fighting infections, mainly through phagocytosis. Macrophages (Choice B) are another type of white blood cell that engulfs and digests cellular debris and pathogens. Langerhans cells (Choice D) are a type of dendritic cell found in the skin and mucosa, primarily involved in antigen presentation.
