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. Rhabdomyolysis can result in serious complications. In addition to muscle pain and weakness, a patient will complain of:
- A. paresthesias.
- B. bone pain.
- C. dark urine.
- D. diarrhea.
Correct answer: C
Rationale: The correct answer is dark urine. Rhabdomyolysis is a condition characterized by the breakdown of muscle tissue, leading to the release of myoglobin into the bloodstream. Myoglobin can cause the urine to appear dark or tea-colored, a condition known as myoglobinuria. This is a classic symptom of rhabdomyolysis. Choices A, B, and D are incorrect as they do not typically present as direct symptoms of rhabdomyolysis. Paresthesias refer to abnormal sensations like tingling or numbness, bone pain is not a primary symptom of rhabdomyolysis, and diarrhea is not a common complaint associated with this condition.
3. A patient is prescribed medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse teach the patient about the proper use of this medication?
- A. Take the medication at the same time each day to maintain consistent hormone levels.
- B. Avoid prolonged sun exposure while taking this medication.
- C. Discontinue the medication if side effects occur.
- D. Apply the medication once a week.
Correct answer: A
Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Consistency in timing helps regulate the hormone levels in the body, ensuring the medication's optimal benefit. Choice B is incorrect as there is no specific need to avoid sun exposure with this medication. Choice C is incorrect because discontinuing the medication without consulting the healthcare provider may not be safe. Choice D is incorrect as medroxyprogesterone acetate is typically taken orally and not applied topically once a week.
4. A 40-year-old man has been living with HIV for several years but experienced a significant decrease in his CD4+ levels a few months ago. The patient has just been diagnosed with Mycobacterium avium complex disease. The nurse should anticipate administering which of the following medications?
- A. Clarithromycin
- B. Pyrazinamide
- C. Rifapentine (Priftin)
- D. Azithromycin
Correct answer: A
Rationale: The correct answer is A: Clarithromycin. In the case of Mycobacterium avium complex disease, a common treatment regimen includes a macrolide antibiotic like clarithromycin or azithromycin in combination with other antimicrobials. Clarithromycin is a key component of the treatment due to its effectiveness against Mycobacterium avium complex. Choice B (Pyrazinamide) is not typically part of the standard treatment for this condition. Choice C (Rifapentine) is mainly used in tuberculosis treatment and is not a primary agent for Mycobacterium avium complex disease. Choice D (Azithromycin) is another suitable macrolide antibiotic for treating Mycobacterium avium complex disease but is not the medication typically used first-line.
5. A 22-year-old was recently diagnosed with acquired immunodeficiency syndrome (AIDS). Which decreased lab finding would be expected to accompany this virus?
- A. CD4 helper T cells
- B. CD8 helper T cells
- C. CDC cells
- D. CDC10 cells
Correct answer: A
Rationale: In a person diagnosed with AIDS, a decrease in CD4 helper T cells is expected. These cells are critical for the immune system's proper functioning, and their reduction weakens the body's ability to fight infections. CD8 helper T cells (Choice B) are not typically decreased in AIDS. CDC cells (Choice C) and CDC10 cells (Choice D) are not relevant terms in this context, making them incorrect choices.
