ATI Pathophysiology Exam
1. A patient is receiving epoetin alfa (Epogen) for anemia. Which of the following adjunctive therapies is imperative with epoetin alfa?
- A. Potassium supplements
- B. Sodium restriction
- C. Iron supplement
- D. Renal dialysis
Correct answer: C
Rationale: The correct answer is C: Iron supplement. When a patient is receiving epoetin alfa for anemia, it is imperative to provide iron supplementation as epoetin alfa works by stimulating the production of red blood cells, which require iron for hemoglobin synthesis. Therefore, iron supplementation is crucial to support the increased erythropoiesis. Choices A, B, and D are incorrect because potassium supplements, sodium restriction, and renal dialysis are not typically indicated as adjunctive therapies with epoetin alfa for anemia.
2. In the ED, a homeless client is brought in with severe hypothermia. The police officers also state that they found a 'bottle of booze' on the sidewalk next to him. This puts the nurse on high alert since alcohol contributes to hypothermia by:
- A. interfering with the appetite center in the brain, causing the person to not respond to hunger cues.
- B. causing the person to have less insulation from body fat.
- C. dulling mental awareness, impairing judgment to seek shelter.
- D. increasing the basal metabolic rate, leading to faster depletion of ATP.
Correct answer: C
Rationale: Alcohol impairs judgment and dulls mental awareness, making a person less likely to seek shelter when experiencing hypothermia. This impaired judgment can lead to risky behaviors that exacerbate the effects of cold exposure. Choice A is incorrect because alcohol does not directly interfere with the appetite center in the brain to the extent described. Choice B is incorrect as alcohol consumption does not directly impact the amount of body fat present. Choice D is incorrect because alcohol does not increase the basal metabolic rate but rather slows it down.
3. Which of the following types of vitamin or mineral deficiency can cause megaloblastic anemia and is associated with lower extremity paresthesias?
- A. Vitamin B12
- B. Folate
- C. Iron
- D. Vitamin K
Correct answer: A
Rationale: The correct answer is Vitamin B12. Vitamin B12 deficiency can lead to megaloblastic anemia and neurological symptoms, including lower extremity paresthesias. Folate deficiency can also cause megaloblastic anemia but typically does not present with neurological symptoms. Iron deficiency leads to microcytic anemia, not megaloblastic anemia. Vitamin K deficiency is associated with coagulation abnormalities, not megaloblastic anemia.
4. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What important instruction should the nurse provide about the use of this medication?
- A. Take the medication with food to prevent nausea.
- B. Discontinue the medication if side effects occur.
- C. Take the medication at the same time each day to maintain consistent hormone levels.
- D. Avoid prolonged sun exposure while taking this medication.
Correct answer: C
Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels. This is crucial for the effectiveness of medroxyprogesterone acetate in treating endometriosis. Choice A is incorrect because there is no specific instruction related to food intake. Choice B is incorrect because discontinuing the medication without consulting a healthcare provider can be harmful. Choice D is unrelated to the administration of medroxyprogesterone acetate and is not a specific consideration for this medication.
5. A patient arrives at her follow-up appointment 1 month post-hysterectomy and complains to the nurse that her scars do not seem to be healing properly. Upon inspection, the nurse notices that the scars are raised but still within the boundaries of the original incisions. The nurse tells the patient this kind of dysfunctional wound healing is called:
- A. Hypertrophic scarring
- B. Dehiscence
- C. Contracture
- D. A keloid
Correct answer: A
Rationale: Hypertrophic scarring occurs when a scar is raised but remains within the boundaries of the original wound, unlike keloids, which extend beyond the wound edges. Dehiscence refers to the separation of wound edges, while contracture involves the tightening or constriction of a scar, leading to limited mobility.
