Pathophysiology Practice Questions
1. Manifestations of Cushing syndrome include:
- A. truncal obesity with thin extremities.
- B. enlargement of face, hands, and feet.
- C. cachexia.
- D. thick scalp hair.
Correct answer: A
Rationale: The correct manifestation of Cushing syndrome is truncal obesity with thin extremities. This occurs due to the redistribution of fat to the face, neck, and abdomen, while the arms and legs remain thin. Choice B, enlargement of face, hands, and feet, is more indicative of acromegaly. Choice C, cachexia, refers to extreme weight loss and muscle wasting, which is typically not seen in Cushing syndrome. Choice D, thick scalp hair, is not a typical manifestation of Cushing syndrome.
2. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What is the expected therapeutic effect of this medication?
- A. Decreased urinary frequency and urgency
- B. Decreased blood pressure
- C. Increased urinary output
- D. Increased hair growth
Correct answer: A
Rationale: The correct answer is A: Decreased urinary frequency and urgency. Finasteride is used to reduce the size of the prostate gland in patients with BPH, which helps alleviate symptoms such as urinary frequency and urgency. Choice B, decreased blood pressure, is incorrect because finasteride is not indicated for lowering blood pressure. Choice C, increased urinary output, is incorrect as finasteride does not typically increase urine production. Choice D, increased hair growth, is incorrect as the primary use of finasteride is not for promoting hair growth but rather for treating BPH.
3. What is the primary therapeutic action of tamsulosin (Flomax) in a male patient with benign prostatic hyperplasia (BPH)?
- A. Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow.
- B. Reduction in prostate size and improvement in urinary symptoms.
- C. Increase in urine flow and relief of urinary obstruction.
- D. Improvement in erectile function.
Correct answer: A
Rationale: The correct answer is A: Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow. Tamsulosin, a medication commonly prescribed for BPH, works by selectively blocking alpha-1 adrenergic receptors in the prostate, causing relaxation of smooth muscles in the prostate and bladder neck. This relaxation reduces the constriction in these areas, improving urinary flow and reducing symptoms such as hesitancy, urgency, frequency, and weak stream. Choice B is incorrect because tamsulosin does not directly reduce the size of the prostate. Choice C is incorrect as tamsulosin primarily acts by relaxing muscles rather than directly increasing urine flow. Choice D is incorrect as tamsulosin is not indicated for improving erectile function.
4. What signs and symptoms most likely prompted this patient to initially seek care?
- A. Malaise and fatigue
- B. Severe diarrhea
- C. Intermittent fever
- D. Dizziness and confusion
Correct answer: B
Rationale: The correct answer is B: Severe diarrhea. A patient who has recently returned from a trip to Nepal with a nongovernmental organization and is seeking care for amebiasis would most likely have been prompted by the symptom of severe diarrhea. Amebiasis is an infection caused by the parasite Entamoeba histolytica, commonly transmitted through contaminated food or water sources in developing countries like Nepal. The hallmark symptom of amebiasis is dysentery, which is characterized by severe diarrhea with blood or mucus in the stool. Malaise and fatigue (choice A) are nonspecific symptoms that may accompany many illnesses and are not specific to amebiasis. Intermittent fever (choice C) is not a typical presenting symptom of amebiasis, which primarily manifests with gastrointestinal symptoms. Dizziness and confusion (choice D) are also not typical symptoms associated with amebiasis.
5. A family member expresses concern to a nurse about behavioral changes in an elderly aunt. Which would cause the nurse to suspect a cognitive impairment disorder?
- A. Decreased interest in activities that she once enjoyed
- B. Fear of being alone at night
- C. Increased complaints of physical ailments
- D. Problems with preparing a meal or balancing her checkbook
Correct answer: D
Rationale: The correct answer is D. Problems with tasks like meal preparation and balancing a checkbook can indicate cognitive impairment, as these activities involve cognitive functions such as memory, attention, and executive function. Choices A, B, and C are less indicative of cognitive impairment. Decreased interest in activities and increased complaints of physical ailments may be related to other factors like depression, while fear of being alone at night could be due to anxiety or other psychological issues.
