ATI Pathophysiology
1. A 10-year-old male presents to his primary care provider reporting wheezing and difficulty breathing. History reveals that both of the child's parents suffer from allergies. Which of the following terms would be used to classify the child?
- A. Desensitized
- B. Atopic
- C. Hyperactive
- D. Autoimmune
Correct answer: B
Rationale: In this case, the correct term to classify the child is 'Atopic.' Atopic individuals have a genetic predisposition to developing allergic conditions, as seen in this patient with a family history of allergies. 'Desensitized' refers to reduced sensitivity to an allergen, which is not the case here. 'Hyperactive' relates to an exaggerated response, and 'Autoimmune' involves the immune system attacking its own cells, neither of which accurately describes the child's classification based on the provided history.
2. When administering azoles in the home setting, the home health nurse should prioritize educational interventions that address what nursing diagnosis?
- A. Risk for injury related to antifungal therapy
- B. Risk for acute confusion related to antifungal therapy
- C. Risk for infection related to antifungal therapy
- D. Risk for falls related to antifungal therapy
Correct answer: A
Rationale: The correct answer is A: Risk for injury related to antifungal therapy. When administering azoles, the priority is to educate patients and caregivers about potential side effects that could lead to injury, such as hepatotoxicity or allergic reactions. Choices B, C, and D are incorrect because acute confusion, infection, and falls are not typically associated with azole therapy.
3. A client with a history of hypertension presents with a severe headache and blurred vision. What is the nurse's priority action?
- A. Administer pain relief medication.
- B. Obtain a stat head CT scan.
- C. Administer antihypertensive medications as prescribed.
- D. Call the healthcare provider immediately.
Correct answer: C
Rationale: The correct answer is to administer antihypertensive medications as prescribed. In a client with a history of hypertension presenting with severe headache and blurred vision, these symptoms could indicate a hypertensive crisis. The priority action is to lower the blood pressure promptly to prevent complications such as stroke, heart attack, or organ damage. Administering antihypertensive medications is crucial in this situation. Administering pain relief medication (Choice A) may temporarily alleviate symptoms but does not address the underlying issue of elevated blood pressure. Obtaining a stat head CT scan (Choice B) may be necessary to rule out other causes but should not delay the administration of antihypertensive medications. Calling the healthcare provider immediately (Choice D) is important but may not address the immediate need to lower blood pressure in a hypertensive crisis.
4. 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.
5. In Guillain-Barre syndrome, what pathophysiologic process underlies the deficits that accompany the degeneration of myelin in the peripheral nervous system (PNS)?
- A. The destruction of myelin results in a reduction in Schwann cell production in the client's PNS.
- B. The lack of myelin surrounding nerve cells compromises the axonal transport system.
- C. Without remyelination, the axon will eventually die.
- D. A deficit of myelin makes the client more susceptible to infection by potential pathogens.
Correct answer: C
Rationale: In Guillain-Barre syndrome, the destruction of myelin leads to axonal damage. If remyelination does not occur, the axon will eventually degenerate and die, impacting nerve function. Choice A is incorrect because the destruction of myelin does not affect Schwann cell production. Choice B is incorrect as the lack of myelin directly affects the conduction of nerve impulses, not the axonal transport system. Choice D is incorrect as a deficit of myelin does not predispose the client to infections by potential pathogens.
