Final Exam Pathophysiology
1. A 20-year-old college student has presented to her campus medical clinic for a scheduled Pap smear. The clinician who will interpret the smear will examine cell samples for evidence of:
- A. Changes in cell shape, size, and organization
- B. Presence of unexpected cell types
- C. Ischemic changes in cell sample
- D. Abnormally high numbers of cells
Correct answer: A
Rationale: The correct answer is changes in cell shape, size, and organization (Choice A). Pap smears are performed to detect potential precancerous or cancerous conditions by examining the cells for any abnormalities in their shape, size, or organization. This helps in identifying early signs of cervical cancer. Choices B, C, and D are incorrect because Pap smears primarily focus on detecting cellular changes associated with cancer, not unexpected cell types, ischemic changes, or abnormally high numbers of cells.
2. What is a characteristic of coronary artery disease (CAD)?
- A. The build-up of infectious by-products in the lymph nodes
- B. Insufficient delivery of oxygenated blood to the myocardium
- C. Insufficient delivery of carbon dioxide to the lungs
- D. The build-up of bile in the stomach and gallbladder
Correct answer: B
Rationale: The correct characteristic of coronary artery disease (CAD) is the insufficient delivery of oxygenated blood to the myocardium. CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle. This lack of oxygenated blood can result in chest pain, known as angina, and if a coronary artery becomes completely blocked, it can cause a heart attack. Choices A, C, and D are incorrect. Choice A refers to an issue related to the lymphatic system, choice C is about gas exchange in the lungs, and choice D describes a problem with bile accumulation in the digestive system, none of which are characteristics of CAD.
3. A nurse is conducting an assessment on a client who presents with symptoms that are characteristic of amyotrophic lateral sclerosis (ALS). What assessment finding would be expected in this client?
- A. Reduced reflexes in all four limbs
- B. Decreased cognitive function
- C. Involuntary muscle contractions
- D. Hyperreflexia
Correct answer: D
Rationale: The correct answer is D: Hyperreflexia. In amyotrophic lateral sclerosis (ALS), hyperreflexia is a common assessment finding due to the degeneration of upper motor neurons. This results in an overactive reflex response to stimuli. Reduced reflexes in all four limbs (choice A) are not typically seen in ALS; instead, hyperreflexia is more common. Decreased cognitive function (choice B) is not a primary characteristic of ALS. Involuntary muscle contractions (choice C) are more indicative of conditions such as dystonia or myoclonus, not ALS.
4. What typically causes contact dermatitis?
- A. Fungal infection
- B. Long-term disorder from gout
- C. Contact with a skin allergen
- D. Staphylococcal infection
Correct answer: C
Rationale: Contact dermatitis is typically caused by contact with a skin allergen that triggers an allergic reaction. Choice A, fungal infection, is incorrect as contact dermatitis is not caused by fungi. Choice B, long-term disorder from gout, is also incorrect as gout is not typically associated with contact dermatitis. Choice D, Staphylococcal infection, is incorrect as contact dermatitis is primarily an allergic reaction rather than a bacterial infection.
5. A patient suffers from dysmenorrhea. Which oral medication will be prescribed that has the ability to provide physiological actions on the neuroendocrine control of ovarian function?
- A. Estrogen
- B. Progestins
- C. Naproxen
- D. Ibuprofen
Correct answer: B
Rationale: Progestins are prescribed for dysmenorrhea as they help reduce menstrual pain by inhibiting ovulation and decreasing the production of prostaglandins. Estrogen (Choice A) is not typically used alone in dysmenorrhea treatment as it can worsen symptoms. Naproxen (Choice C) and Ibuprofen (Choice D) are nonsteroidal anti-inflammatory drugs (NSAIDs) commonly used to relieve pain associated with dysmenorrhea, but they do not directly affect the neuroendocrine control of ovarian function like progestins do.
