Pathophysiology Practice Questions
1. A 60-year-old man presents with painless hematuria. Which of the following should be the next step in the evaluation?
- A. Urinalysis
- B. Renal ultrasound
- C. Cystoscopy
- D. Intravenous pyelogram
Correct answer: C
Rationale: In a 60-year-old man presenting with painless hematuria, the next step in the evaluation should be cystoscopy. Cystoscopy is recommended to assess the cause of hematuria, particularly to rule out bladder cancer, which is more common in older individuals. Urinalysis (Choice A) can provide initial information but may not definitively diagnose the underlying cause. Renal ultrasound (Choice B) and intravenous pyelogram (Choice D) are imaging studies that may be considered later in the evaluation process but are not the initial step for painless hematuria.
2. Which of the following are signs and symptoms of myocardial infarction?
- A. Persistent chest pain which may radiate to the arm
- B. Brief sternal chest pain on inspiration
- C. Rapid respirations with left-sided weakness and numbness
- D. Left upper quadrant abdominal pain which radiates to the back and shoulder
Correct answer: A
Rationale: The correct answer is A. Persistent chest pain that may radiate to the arm is a classic symptom of myocardial infarction. This pain is typically described as crushing, pressure-like, or squeezing. Choice B is incorrect because brief sternal chest pain on inspiration is not characteristic of myocardial infarction. Choice C is incorrect because rapid respirations with left-sided weakness and numbness are not typical symptoms of myocardial infarction. Choice D is incorrect because left upper quadrant abdominal pain that radiates to the back and shoulder is not a common presentation of myocardial infarction.
3. On the advice of his brother, a 53-year-old man has made an appointment to request a prescription for Viagra. The nurse who works at the clinic is reviewing the man's medical history and would recognize what health problem as being prohibitive to this treatment?
- A. Type 2 diabetes, treated with metformin
- B. Hypercholesterolemia, treated with simvastatin
- C. Angina, treated with nitroglycerin
- D. Hypertension, treated with metoprolol
Correct answer: C
Rationale: Nitroglycerin is contraindicated with Viagra due to their combined effects on lowering blood pressure, which can result in a severe drop and potentially life-threatening complications. Using both medications together can lead to hypotension, putting the patient at risk. Therefore, the presence of angina treated with nitroglycerin would make prescribing Viagra unsafe. Choices A, B, and D are not directly contraindicated with Viagra and can be managed concurrently with this treatment.
4. Why is the administration of benzene hexachloride (Lindane) for the treatment of scabies applied in small quantities?
- A. Excessive applications will lead to central nervous system toxicity.
- B. Excessive applications will cause irritation, rash, and inflammation.
- C. Excessive applications will cause headaches, dizziness, and diarrhea.
- D. Excessive applications will lead to anorexia and cachexia.
Correct answer: A
Rationale: The rationale for instructing the patient to apply benzene hexachloride (Lindane) in small quantities for scabies treatment is that excessive applications can lead to central nervous system toxicity. Lindane is a neurotoxin, and overuse or incorrect application can result in adverse effects on the central nervous system, such as seizures, dizziness, and even death. Choices B, C, and D are incorrect because they do not reflect the specific toxic effects associated with Lindane, which primarily affects the central nervous system rather than causing skin irritation, gastrointestinal symptoms, or metabolic issues.
5. Which of the following is found in higher concentrations within intracellular fluid?
- A. Magnesium
- B. Sodium
- C. Chloride
- D. Bicarbonate
Correct answer: A
Rationale: Magnesium is the correct answer as it is found in higher concentrations within intracellular fluid, where it plays vital roles in various cellular functions. Sodium, chloride, and bicarbonate are predominantly found in extracellular fluid rather than intracellular fluid, making them incorrect choices for this question.
