Final Exam Pathophysiology
1. What instruction should the nurse include in this patient's health education regarding chloroquine phosphate (Aralen) for malaria prophylaxis?
- A. “Take your pill on the same day each week.â€
- B. “Watch out for any unusual rash on your trunk and arms, but this isn't cause for concern.â€
- C. “Remember to take your chloroquine on an empty stomach.â€
- D. “We'll provide you with enough syringes and teach you how to inject the drug.â€
Correct answer: A
Rationale: The correct instruction for the nurse to include in this patient's health education regarding chloroquine phosphate (Aralen) for malaria prophylaxis is to “Take your pill on the same day each week.†This is essential because chloroquine is typically taken once a week on the same day to ensure consistent protection against malaria. Choice B is incorrect because while rashes are a possible side effect of chloroquine, they are not a usual occurrence and should be reported to the healthcare provider. Choice C is incorrect because chloroquine does not need to be taken on an empty stomach. Choice D is incorrect as chloroquine is typically administered orally, not by injection.
2. What physiological reaction occurs in the body with the 'Fight or flight' response?
- A. Increased heart rate
- B. Constricted pupils
- C. Decreased blood pressure
- D. Decreased heart rate
Correct answer: A
Rationale: The 'fight or flight' response is a primal physiological reaction that prepares the body to respond to a perceived threat or danger. This response triggers an increase in heart rate to pump more blood to the muscles and vital organs, preparing the body for action. Choice B, 'Constricted pupils,' is part of the 'fight or flight' response as well, as it helps improve focus and vision. Choice C, 'Decreased blood pressure,' is incorrect because blood pressure typically increases to ensure adequate circulation during the 'fight or flight' response. Choice D, 'Decreased heart rate,' is incorrect as the heart rate increases to supply more oxygen and nutrients to the body during times of stress.
3. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?
- A. History of peptic ulcer disease
- B. Use of nitrates
- C. Use of antihypertensive medications
- D. History of hypertension
Correct answer: B
Rationale: The correct answer is B: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates combined with sildenafil can lead to a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of peptic ulcer disease, use of antihypertensive medications, or a history of hypertension are not direct contraindications for sildenafil use.
4. In clients with a cognitive impairment disorder, the phenomenon of increased confusion in the early evening hours is called:
- A. Aphasia.
- B. Agnosia.
- C. Sundowning.
- D. Confabulation.
Correct answer: C
Rationale: The correct answer is C: Sundowning. Sundowning is a phenomenon where individuals with cognitive impairment experience increased confusion and agitation in the late afternoon or early evening. This often occurs in conditions like dementia. Choice A, Aphasia, refers to a language disorder affecting a person's ability to communicate. Choice B, Agnosia, is the inability to recognize objects. Choice D, Confabulation, is the production of false memories without the intention to deceive, often seen in conditions like Korsakoff's syndrome.
5. Which of the following best describes Cushing’s syndrome?
- A. Hypersecretion of growth hormone
- B. Excessive production of cortisol by the adrenal glands
- C. Insufficient production of insulin
- D. Increased levels of ACTH
Correct answer: B
Rationale: Cushing’s syndrome is characterized by the excessive production of cortisol by the adrenal glands, not growth hormone (Choice A), insulin (Choice C), or ACTH (Choice D). The increased cortisol levels lead to a variety of symptoms associated with Cushing’s syndrome.
