ATI Pathophysiology Final Exam
1. A patient has suffered from several infections in the last 6 months and unexplained impaired wound healing. What assessment should the nurse prioritize?
- A. Assess for pain.
- B. Assess for nutritional deficiencies.
- C. Assess genetic tendency for infection.
- D. Assess for edema and decreased hemoglobin.
Correct answer: B
Rationale: In this scenario, the patient's history of multiple infections and impaired wound healing indicates a potential issue with their immune system and overall health. Therefore, the nurse should prioritize assessing for nutritional deficiencies. Proper nutrition is essential for a healthy immune response and wound healing. Assessing for pain (choice A) may be important but addressing the root cause of the recurrent infections and impaired wound healing is crucial. Genetic tendency for infection (choice C) would be a less immediate concern compared to assessing for nutritional deficiencies. Edema and decreased hemoglobin (choice D) are not the most relevant assessments based on the patient's symptoms.
2. What is reperfusion injury?
- A. Healing bone tissue after fracture
- B. Skin wound tunneling and shear
- C. Secondary injury after reestablishing blood flow
- D. Injury after blood transfusion
Correct answer: C
Rationale: Reperfusion injury refers to the secondary injury that occurs after blood flow is reestablished following ischemia. This process leads to tissue damage due to the sudden reintroduction of oxygen and nutrients, causing oxidative stress, inflammation, and cell death. Choice A is incorrect as it describes the normal healing process of bone tissue after a fracture. Choice B is incorrect as it describes specific mechanisms related to skin wounds, not reperfusion injury. Choice D is incorrect as it refers to a different concept, which is adverse reactions or complications that can occur after a blood transfusion, not reperfusion injury.
3. A 17-year-old woman has come to the clinic requesting emergency contraception after having unprotected sex 24 hours ago. What medication is the clinician most likely to prescribe?
- A. Levonorgestrel (Plan B)
- B. Mifepristone (RU-486)
- C. Ulipristal acetate (ella)
- D. Estradiol (Estrace)
Correct answer: A
Rationale: The correct answer is A: Levonorgestrel (Plan B). Levonorgestrel is the most commonly prescribed medication for emergency contraception within 72 hours of unprotected intercourse. It is effective when taken within 72 hours after intercourse, with better efficacy the sooner it is taken. Choice B, Mifepristone (RU-486), is not indicated for emergency contraception but is used for medical abortion. Choice C, Ulipristal acetate (ella), is another option for emergency contraception that is effective up to 120 hours after unprotected intercourse. Choice D, Estradiol (Estrace), is not used for emergency contraception.
4. When reviewing the purpose/action of neurotransmitters as they interact with different receptors, the nursing instructor gives an example using acetylcholine. When acetylcholine is released at the sinoatrial node in the right atrium of the heart, it is:
- A. positively charged.
- B. inhibitory.
- C. overstimulated.
- D. dormant.
Correct answer: B
Rationale: Acetylcholine acts as an inhibitory neurotransmitter at the sinoatrial node. It slows down the heart rate by decreasing the firing rate of the sinoatrial node, which serves as the heart's natural pacemaker. Neurotransmitters do not have a charge, so choice A is incorrect. Choice C is wrong as overstimulation is not a characteristic of acetylcholine at the sinoatrial node. Choice D is also incorrect because acetylcholine actively influences heart rate regulation when released at the sinoatrial node.
5. A primiparous woman tells the nurse that she and her partner are highly reluctant to have their infant vaccinated, stating, “We've read that vaccines can potentially cause a lot of harm, so we're not sure we want to take that risk.” How should the nurse respond to this family's concerns?
- A. “Vaccinations are not without some risks, but these are far exceeded by the potential benefits they offer in preventing serious diseases.”
- B. “The potential risks of vaccinations have been investigated and determined to be minimal compared to the benefits of protecting your child from potentially life-threatening diseases.”
- C. “It is important to follow state laws regarding vaccines, but I understand your concerns. Let's discuss the specific risks and benefits of vaccines for your child.”
- D. “Vaccines indeed cause several serious adverse effects, but these are usually treated effectively, and the benefits of vaccination in preventing diseases far outweigh the risks.”
Correct answer: B
Rationale: When addressing concerns about vaccination, it is crucial to provide accurate information to help parents make informed decisions. Choice B is the most appropriate response as it acknowledges the concerns of the family while emphasizing that the potential risks of vaccinations are minimal compared to the significant benefits of protecting the child from serious diseases. This response shows empathy towards the parents' concerns while also highlighting the importance of vaccination in preventing life-threatening illnesses. Choice A is incorrect because it does not emphasize the significant benefits of vaccination in preventing diseases, which may not effectively address the family's concerns. Choice C is incorrect as it focuses more on state laws rather than addressing the family's specific concerns about vaccine safety. Choice D is incorrect as it may increase the family's anxiety by highlighting adverse effects without adequately emphasizing the benefits of vaccination in disease prevention.
