Pathophysiology Final Exam

1. 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.

2. A patient's anemia is described as having erythrocytes that demonstrate anisocytosis. The nurse would recognize the erythrocytes as:

A. Pale in color
B. Present in various sizes
C. Able to assume various shapes
D. Live only a few days

Correct answer: B

Rationale: The correct answer is B: 'Present in various sizes.' Anisocytosis refers to erythrocytes that are present in various sizes, indicating an abnormality in the uniformity of red blood cell size. Choice A is incorrect because anisocytosis does not refer to the color of erythrocytes. Choice C is incorrect as anisocytosis does not involve the shape of erythrocytes. Choice D is incorrect as anisocytosis does not determine the lifespan of erythrocytes.

3. Which of the following organs are primarily affected by poorly managed hypertension?

A. The bladder and urethra
B. The brain and skin
C. The heart and kidneys
D. The stomach and intestines

Correct answer: C

Rationale: Poorly managed hypertension primarily affects the heart and kidneys. The heart is at risk of conditions like heart failure due to the increased workload from elevated blood pressure. The kidneys can suffer damage from longstanding hypertension, leading to kidney disease. Choices A, B, and D are incorrect because the bladder, urethra, brain, skin, stomach, and intestines are not the primary organs affected by poorly managed hypertension.

4. What property is found in clients with metastatic cancer?

A. Tumors that are well encapsulated
B. Tumors with slow, stable growth
C. Cells that are genetically stable
D. Cells invading local tissue and overrunning neighboring cells

Correct answer: D

Rationale: Metastatic cancer is characterized by cells that invade local tissue and overrun neighboring cells. Therefore, the correct answer is D. Choices A, B, and C are incorrect because metastatic cancer is associated with aggressive behavior where cells invade and spread to other parts of the body, rather than being well encapsulated, growing slowly, or being genetically stable.

5. Which of the following accurately describes the pathophysiology of asthma?

A. Chronic inflammation of the bronchial lining
B. Narrowing of the airway due to bronchoconstriction
C. Damage to alveoli reducing lung elasticity
D. Overproduction of mucus by the goblet cells

Correct answer: B

Rationale: The correct answer is B: "Narrowing of the airway due to bronchoconstriction." In asthma, there is an inflammatory response that leads to bronchoconstriction, causing the airways to narrow and making it difficult to breathe. Choice A is incorrect as chronic inflammation is a feature of asthma but not the primary pathophysiological mechanism. Choice C is incorrect as damage to alveoli is more characteristic of conditions like emphysema. Choice D is incorrect as overproduction of mucus is a feature of chronic bronchitis, not asthma.
