When explanation should the nurse give to a male client on why benign prostatic hyperplasia (BPH) often causes urinary retention?

Inflammation causes spasms of the gland.

Abnormal growth results in loss of bladder muscle.

Nerve compression decreases the sensation that the bladder is full.

The enlarged gland compresses the urethra.

Answer and Explanation

The Correct Answer is D

Choice A reason: Inflammation may occur in prostatitis, not typically in BPH. BPH causes urinary retention via physical obstruction from gland enlargement, not spasms. Inflammation is not the primary mechanism, making this incorrect for explaining why BPH leads to retention in the client’s urinary symptoms.

Choice B reason: Abnormal growth in BPH does not cause loss of bladder muscle. The enlarged prostate compresses the urethra, obstructing urine flow. Bladder muscle may weaken over time from chronic obstruction, but this is secondary, making this incorrect for the primary cause of urinary retention.

Choice C reason: Nerve compression is not a primary BPH mechanism. BPH causes retention by mechanically obstructing the urethra, not by impairing bladder sensation. Sensory changes may occur in neurological conditions, but in BPH, physical compression is the cause, making this incorrect for the client’s retention.

Choice D reason: BPH causes the prostate to enlarge, compressing the urethra and obstructing urine flow, leading to urinary retention. This mechanical blockage is the primary pathophysiological mechanism, causing symptoms like hesitancy or incomplete voiding. This explanation aligns with urological evidence, accurately addressing the client’s condition.

Correct Answer is D

Explanation

Choice A reason: Decreased acetylcholine is not the primary cause of Parkinson’s disease. Parkinson’s results from dopamine loss in the substantia nigra, disrupting motor control. Acetylcholine imbalance may occur in other conditions like Alzheimer’s, but it is not the pathophysiological basis for Parkinson’s motor symptoms.

Choice B reason: Increased serotonin is not linked to Parkinson’s disease. Parkinson’s is caused by dopamine depletion in the basal ganglia, leading to motor dysfunction. Serotonin imbalances may affect mood, but they are not the core mechanism, making this incorrect for the disease’s pathophysiological basis.

Choice C reason: Disruption in the myelin sheath occurs in multiple sclerosis, not Parkinson’s. Parkinson’s involves neuronal loss in the substantia nigra, reducing dopamine. Myelin is unrelated to Parkinson’s motor symptoms, making this incorrect, as dopamine deficiency is the established pathophysiological mechanism driving the disease.

Choice D reason: Parkinson’s disease is caused by a diminished amount of dopamine due to degeneration of substantia nigra neurons. Dopamine deficiency disrupts basal ganglia function, causing tremors, rigidity, and bradykinesia. This is the core pathophysiological basis, supported by neurological evidence linking dopamine loss to Parkinson’s symptoms.

A. Decreased red blood cell count. B. Elevated low-density lipoprotein (LDL). C. Decreased triglycerides. D. Increased high-density lipoprotein (HDL).

Correct Answer is B

Explanation

Choice A reason: Decreased red blood cell count indicates anemia, which may cause fatigue or exacerbate ischemia but is not a direct marker of atherosclerosis. Angina results from arterial plaque buildup, driven by elevated LDL cholesterol. Low RBCs do not contribute to plaque formation, making this inconsistent with the diagnosis.

Choice B reason: Elevated LDL cholesterol is a primary risk factor for atherosclerosis, as it deposits in arterial walls, forming plaques that narrow coronary arteries, causing angina. In overweight smokers with stress, high LDL is a key driver of cardiovascular disease, directly supporting the pathophysiology of angina, per evidence-based lipid guidelines.

Choice C reason: Decreased triglycerides are not associated with atherosclerosis, which is driven by high LDL and low HDL. Triglycerides contribute to cardiovascular risk when elevated, but low levels do not cause angina. Elevated LDL is the critical lipid abnormality in this client’s angina due to coronary artery narrowing.

Choice D reason: Increased HDL cholesterol is protective against atherosclerosis, as it removes cholesterol from arteries, reducing plaque formation. Angina is associated with low HDL and high LDL. High HDL would mitigate, not cause, the client’s condition, making this inconsistent with the diagnosis of atherosclerosis-induced angina.
