Pathophysiology Practice Questions
1. In which of the following cases is dehydration more likely to occur?
- A. A 50-year-old woman who is a bodybuilder
- B. A 50-year-old man who is morbidly obese
- C. A 10-year-old child who is thin
- D. A 30-year-old with multiple sclerosis
Correct answer: B
Rationale: The correct answer is B. Morbid obesity increases the risk of dehydration due to the larger body surface area and potential for greater insensible losses. Choices A, C, and D are less likely to experience dehydration compared to a morbidly obese individual.
2. When starting on oral contraceptives, what should the nurse emphasize about the potential interactions with other medications?
- A. Oral contraceptives can be less effective when taken with certain antibiotics.
- B. Oral contraceptives are less effective when taken with food.
- C. Oral contraceptives are effective immediately after starting.
- D. Oral contraceptives have no interactions with other medications.
Correct answer: A
Rationale: The correct answer is A. Oral contraceptives can be less effective when taken with certain antibiotics, so patients should be informed about the potential need for additional contraception. Choice B is incorrect because taking oral contraceptives with food does not affect their effectiveness. Choice C is incorrect because oral contraceptives may take some time to become fully effective. Choice D is incorrect because oral contraceptives can interact with other medications, especially certain antibiotics, affecting their efficacy.
3. A nurse is caring for a patient who is being treated with clomiphene citrate (Clomid) for infertility. What side effect should the nurse warn the patient about?
- A. Headaches and visual disturbances
- B. Nausea and vomiting
- C. Hot flashes and abdominal discomfort
- D. Fatigue and depression
Correct answer: C
Rationale: The correct answer is C: 'Hot flashes and abdominal discomfort.' Clomiphene citrate, commonly known as Clomid, can lead to hot flashes and abdominal discomfort as side effects. It is important for the nurse to warn the patient about these potential effects. Choices A, B, and D are incorrect because headaches and visual disturbances, nausea and vomiting, as well as fatigue and depression are not commonly associated with clomiphene citrate use.
4. Which of the following are signs and symptoms of myocardial infarction?
- A. Persistent chest pain which may radiate to the arm
- B. Brief sternal chest pain on inspiration
- C. Rapid respirations with left-sided weakness and numbness
- D. Left upper quadrant abdominal pain which radiates to the back and shoulder
Correct answer: A
Rationale: The correct answer is A. Persistent chest pain that may radiate to the arm is a classic symptom of myocardial infarction. This pain is typically described as crushing, pressure-like, or squeezing. Choice B is incorrect because brief sternal chest pain on inspiration is not characteristic of myocardial infarction. Choice C is incorrect because rapid respirations with left-sided weakness and numbness are not typical symptoms of myocardial infarction. Choice D is incorrect because left upper quadrant abdominal pain that radiates to the back and shoulder is not a common presentation of myocardial infarction.
5. What is the primary action of bisphosphonates when prescribed to a patient with osteoporosis?
- A. It inhibits bone resorption, which helps maintain bone density.
- B. It stimulates new bone formation by increasing osteoblast activity.
- C. It increases calcium absorption in the intestines, which helps build stronger bones.
- D. It decreases calcium excretion by the kidneys, helping to maintain bone density.
Correct answer: A
Rationale: The correct answer is A: "It inhibits bone resorption, which helps maintain bone density." Bisphosphonates work by inhibiting bone resorption carried out by osteoclasts, thereby preventing the breakdown of bones and helping to maintain or increase bone density in patients with osteoporosis. Choices B, C, and D are incorrect because bisphosphonates do not directly stimulate new bone formation, increase calcium absorption in the intestines, or decrease calcium excretion by the kidneys.
