Pathophysiology Exam 1 Quizlet
1. A male patient with erectile dysfunction is prescribed sildenafil (Viagra). What specific instruction should the nurse provide to ensure the safe use of this medication?
- A. Take the medication with food to prevent nausea.
- B. Avoid taking nitrates while on this medication.
- C. Take the medication at bedtime to ensure absorption during sleep.
- D. Take the medication with milk to enhance absorption.
Correct answer: B
Rationale: The correct instruction the nurse should provide is to avoid taking nitrates while on sildenafil (Viagra). Combining sildenafil with nitrates can result in severe hypotension due to additive vasodilatory effects. Choice A is incorrect because sildenafil can be taken with or without food. Choice C is incorrect as there is no specific requirement to take sildenafil at bedtime. Choice D is incorrect as taking sildenafil with milk has not been shown to enhance its absorption.
2. Which of the following steps occurs first during hemostasis?
- A. Vascular spasm
- B. Platelet plug
- C. Coagulation
- D. Dissolution of the clot
Correct answer: A
Rationale: Vascular spasm is the initial step in hemostasis, where blood vessels constrict to reduce blood flow to the injured area. This constriction helps limit blood loss until further steps like platelet plug formation and coagulation can take place. Platelet plug formation and coagulation occur after the vascular spasm, making them incorrect choices. Dissolution of the clot happens much later in the healing process, after the injury has sufficiently healed.
3. A nurse is teaching a young adult patient about oral contraceptives, which the patient will soon begin taking. The patient's primary concern is the effectiveness of the medication in preventing pregnancy. The nurse should teach the patient that oral contraceptives, when taken consistently, are how effective in preventing pregnancy?
- A. Between 96% and 98%
- B. Approximately 98.5%
- C. Highly effective, but partially dependent on genetic factors
- D. Nearly 100%
Correct answer: D
Rationale: When taken correctly, estrogen–progestin contraceptive preparations are nearly 100% effective in preventing pregnancy. Choices A, B, and C are incorrect. Choice A suggests a range below the actual effectiveness, choice B provides a specific percentage that is not accurate, and choice C introduces the concept of genetic factors which is not relevant to the effectiveness of oral contraceptives.
4. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What should the nurse include in the patient teaching?
- A. Take the medication with food to prevent nausea.
- B. Take the medication at the same time each day to maintain consistent hormone levels.
- C. Avoid prolonged sun exposure while taking this medication.
- D. Discontinue the medication if side effects occur.
Correct answer: B
Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. This is crucial for the drug to work optimally. Choice A is incorrect because medroxyprogesterone acetate does not necessarily need to be taken with food to prevent nausea. Choice C is not directly related to the medication's administration and is not a common teaching point for this drug. Choice D is incorrect as discontinuing the medication abruptly can lead to adverse effects and is not recommended without consulting a healthcare provider.
5. In an adult patient suspected of having an androgen deficiency and considering treatment with testosterone, the use of testosterone would be most complicated by the presence of what preexisting health problem?
- A. Urinary incontinence
- B. BPH
- C. Chronic renal failure
- D. Type 2 diabetes
Correct answer: B
Rationale: The correct answer is BPH (Benign Prostatic Hyperplasia). Testosterone therapy can worsen symptoms of BPH by potentially increasing prostate size and stimulating the growth of prostate tissue. This can lead to complications such as urinary retention and the need for further medical interventions. Urinary incontinence (choice A) can have various causes but is not directly related to testosterone therapy. Chronic renal failure (choice C) and Type 2 diabetes (choice D) are not typically contraindications for testosterone therapy in the context of androgen deficiency.
