Pathophysiology Practice Questions
1. Nurse Isabelle enters the room of a client with a cognitive impairment disorder and asks what day of the week it is, what the date, month, and year are, and where the client is. The nurse is attempting to assess:
- A. confabulation.
- B. delirium.
- C. orientation.
- D. perseveration.
Correct answer: C
Rationale: The correct answer is C: "orientation." Nurse Isabelle is assessing the client's orientation by asking questions about time (day, date, month, year), place, and person. This assessment helps determine the client's awareness of their surroundings and situation. Confabulation (choice A) is the unintentional fabrication of details or events to fill in memory gaps and is not being assessed in this scenario. Delirium (choice B) is a state of acute confusion and disorientation, usually with a rapid onset, which is different from assessing orientation. Perseveration (choice D) refers to the persistent repetition of a response, statement, or behavior and is not the focus of the assessment being conducted by Nurse Isabelle in this situation.
2. A patient was sneezing frequently after a few days of allergic rhinitis, and she noticed her eye became red. She denies any trauma, eye pain, or visual disturbance. Physical examination reveals a subconjunctival hemorrhage. Which statement is accurate pertaining to this case?
- A. The hemorrhage will resolve without treatment within 2 weeks.
- B. The patient should be referred for immediate ophthalmologic examination.
- C. Corticosteroid eye drops will be prescribed to reduce the bleeding.
- D. Antibiotic eye drops will be prescribed to prevent infection.
Correct answer: A
Rationale: The correct answer is A: 'The hemorrhage will resolve without treatment within 2 weeks.' Subconjunctival hemorrhage typically resolves on its own without treatment. It is a self-limiting condition that does not require specific intervention. Choice B is incorrect as immediate ophthalmologic examination is not necessary for subconjunctival hemorrhage unless there are other concerning symptoms or risk factors present. Choice C is incorrect because corticosteroid eye drops are not typically used for subconjunctival hemorrhage. Choice D is also incorrect as antibiotic eye drops are not indicated since subconjunctival hemorrhage is not due to an infection.
3. Prior to leaving on a backpacking trip to Southeast Asia, a college student has received a tetanus booster shot. This immunization confers protection by way of what immune process?
- A. Passive natural immunity
- B. Active natural immunity
- C. Passive artificial immunity
- D. Active artificial immunity
Correct answer: D
Rationale: The correct answer is D: Active artificial immunity. A tetanus booster shot confers protection through active artificial immunity. Active immunity involves the body producing its antibodies in response to an antigen, providing long-lasting protection. In this case, the tetanus booster shot triggers the student's immune system to produce specific antibodies against tetanus toxins. Choices A, B, and C are incorrect because passive immunity does not involve the individual's immune system producing antibodies; instead, it involves the direct transfer of antibodies from another source (natural or artificial) for immediate, but temporary, protection.
4. 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.
5. Which of the following is NOT an example of clinical manifestations of leukemia and lymphoma?
- A. Fatigue
- B. Increased risk of bleeding
- C. Increased risk of infections
- D. Increased energy and strength
Correct answer: D
Rationale: The correct answer is D: Increased energy and strength. Leukemia and lymphoma typically present with symptoms such as fatigue, weakness, increased risk of bleeding, and increased risk of infections. Patients with these conditions often experience a lack of energy and strength due to the disease's impact on the body. Therefore, increased energy and strength are not typical manifestations of leukemia and lymphoma.
