ATI Pathophysiology Exam 1
1. Which of the following hormones helps to raise the blood sugar level to help maintain homeostasis?
- A. Antidiuretic hormone (ADH)
- B. Insulin
- C. Glucagon
- D. Thyroxine
Correct answer: C
Rationale: The correct answer is C, Glucagon. Glucagon helps raise blood sugar levels by stimulating the liver to release stored glucose into the bloodstream, thus aiding in maintaining homeostasis. Antidiuretic hormone (ADH), choice A, functions in regulating water balance in the body, not blood sugar levels. Insulin, choice B, lowers blood sugar levels by facilitating glucose uptake by cells. Thyroxine, choice D, is a hormone produced by the thyroid gland that regulates metabolism and has no direct effect on blood sugar levels.
2. A 45-year-old woman has been prescribed conjugated estrogens (Premarin) for the treatment of menopausal symptoms. What should the nurse include in the patient teaching?
- A. Increase fluid intake to prevent dehydration.
- B. Avoid smoking while taking this medication.
- C. Increase the intake of high-calcium foods.
- D. Take the medication at bedtime to prevent insomnia.
Correct answer: B
Rationale: The correct answer is to 'Avoid smoking while taking this medication' because patients taking conjugated estrogens should avoid smoking due to the increased risk of cardiovascular events. Increasing fluid intake to prevent dehydration is a good practice but not specifically related to conjugated estrogens. Increasing the intake of high-calcium foods may be beneficial for bone health but is not directly related to the medication. Taking the medication at bedtime to prevent insomnia is not a specific teaching point for conjugated estrogens.
3. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What key instruction should the nurse provide regarding the use of this medication?
- A. Take the medication at the same time each day to maintain consistent hormone levels.
- B. Medroxyprogesterone should be taken with food to reduce gastrointestinal upset.
- C. Medroxyprogesterone should be discontinued if side effects occur.
- D. Medroxyprogesterone should be taken once a week to maintain effectiveness.
Correct answer: A
Rationale: The correct instruction the nurse should provide regarding the use of medroxyprogesterone acetate (Provera) for endometriosis is to take the medication at the same time each day. This helps to maintain consistent hormone levels and ensures the effectiveness of the treatment. Choice B is incorrect because medroxyprogesterone should be taken without regard to meals. Choice C is incorrect because side effects should be reported to the healthcare provider for evaluation rather than discontinuing the medication without medical advice. Choice D is incorrect as medroxyprogesterone is usually taken daily, not weekly, for the treatment of endometriosis.
4. A patient is starting on a new oral contraceptive. What should the nurse emphasize about the timing of the medication?
- A. Take the medication at the same time each day to maintain stable hormone levels.
- B. Oral contraceptives should be taken in the morning to avoid nighttime side effects.
- C. Oral contraceptives can be taken at any time of day as long as the schedule is consistent.
- D. Oral contraceptives are effective immediately upon starting, regardless of timing.
Correct answer: A
Rationale: The correct answer is A. It is crucial for patients taking oral contraceptives to take the medication at the same time each day to maintain stable hormone levels and ensure their effectiveness in preventing pregnancy. Choice B is incorrect because there is no specific requirement to take oral contraceptives in the morning. Choice C is incorrect because consistency in timing is essential, but it should be at the same time each day. Choice D is incorrect because oral contraceptives may take some time to reach peak effectiveness, so it is important to emphasize the need for consistent timing.
5. Canola oil produced from genetically modified canola plants altered to be herbicide-resistant is an example of a:
- A. pesticide-free food.
- B. saturated fat food.
- C. genetically modified food.
- D. product that is pure.
Correct answer: C
Rationale: The correct answer is 'genetically modified food.' Canola oil derived from genetically modified canola plants falls into this category because the plant's genome has been altered to exhibit herbicide resistance. This genetic modification makes it a genetically modified food. Choice A, 'pesticide-free food,' is incorrect as the genetic modification is to resist herbicides, not pesticides. Choice B, 'saturated fat food,' is incorrect as it does not accurately describe the genetic modification of the canola plants. Choice D, 'product that is pure,' is too vague and does not address the genetic modification aspect of the canola plants.
