Pathophysiology Practice Questions
1. A student nurse was asked which of the following best describes dementia. Which of the following best describes the condition?
- A. Memory loss as a natural consequence of aging
- B. Difficulty coping with physical and psychological changes
- C. Severe cognitive impairment that occurs rapidly
- D. Loss of cognitive abilities, impairing the ability to perform activities of daily living
Correct answer: D
Rationale: The correct answer is D. Dementia is characterized by a loss of cognitive abilities that impairs the individual's capacity to perform activities of daily living. Choice A is incorrect because dementia is not simply memory loss related to aging but involves broader cognitive deficits. Choice B is incorrect as it does not capture the comprehensive cognitive decline seen in dementia. Choice C is incorrect as dementia typically progresses gradually rather than rapidly, and it is not solely about severe cognitive impairment but also impacts daily functioning.
2. A patient with a history of venous thromboembolism is being considered for hormone replacement therapy (HRT). What should the nurse discuss with the patient regarding the risks of HRT?
- A. Discuss the potential for increased bone density.
- B. Discuss the potential for an increased risk of cardiovascular events.
- C. Discuss the potential for a reduced risk of breast cancer.
- D. Discuss the potential for improved mood and energy levels.
Correct answer: B
Rationale: The correct answer is B because hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including venous thromboembolism. Patients with a history of venous thromboembolism are at higher risk, so discussing this potential risk is crucial. Choice A, increased bone density, is not a major risk of HRT. Choice C, reduced risk of breast cancer, is not a common discussion point regarding HRT risks. Choice D, improved mood and energy levels, is more related to the benefits of HRT rather than its risks.
3. 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.”
- B. “Watch out for any unusual rash on your trunk and arms, but this isn't cause for concern.”
- C. “Remember to take your chloroquine on an empty stomach.”
- D. “We'll provide you with enough syringes and teach you how to inject the drug.”
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.
4. Which of the following is a characteristic of the human immunodeficiency virus (HIV), which causes AIDS?
- A. HIV only infects B cells
- B. HIV is a retrovirus
- C. Infection does not require a host cell receptor
- D. After infection, cell death is immediate
Correct answer: B
Rationale: The correct answer is B. HIV is a retrovirus that infects T cells and leads to the gradual destruction of the immune system. Choice A is incorrect because HIV infects T cells primarily, not just B cells. Choice C is incorrect because HIV infection requires host cell receptors for entry. Choice D is incorrect because cell death after HIV infection is not immediate; instead, the virus gradually weakens the immune system over time.
5. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What is a key contraindication that the nurse should review with the patient?
- A. History of hypertension
- B. Use of nitrates
- C. Use of antihypertensive medications
- D. History of peptic ulcer disease
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 and sildenafil both act as vasodilators, and their combined use can lead to a dangerous drop in blood pressure. Choices A, C, and D are incorrect because having a history of hypertension, using antihypertensive medications, or having a history of peptic ulcer disease are not key contraindications for sildenafil use.
