A 57-year-old male presents with difficulty initiating urination. The patient notes darker-colored urine than normal. Treatment: Schedule transurethral prostate resection (TURP) Which diagnosis is described?
Prostatitis
Epididymitis
Benign prostatic hyperplasia
Testicular cancer
The Correct Answer is C
Benign prostatic hyperplasia (BPH) is a noncancerous enlargement of the prostate gland, a walnut-sized organ that surrounds the urethra in men. The enlarged prostate can compress the urethra and cause urinary problems, such as difficulty starting or stopping urination, weak urine stream, frequent or urgent urination, and blood in the urine. Transurethral prostate resection (TURP) is a surgical procedure that removes excess prostate tissue and relieves the pressure on the urethra.

Correct Answer is C
Explanation
Osmolarity is a measure of the concentration of solutes in a solution. When the osmolarity of the bloodstream increases due to blood loss, water will move from areas of lower osmolarity to areas of higher osmolarity by osmosis. This means that water will move from the extracellular fluid (the fluid outside the cells) to the intracellular fluid (the fluid inside the cells) to balance the osmotic pressure. As a result, the extracellular fluid volume will decrease and the intracellular fluid volume will increase, causing the cells to expand.
Correct Answer is D
Explanation
Diabetes insipidus is a disorder of water balance caused by a deficiency of antidiuretic hormone (ADH) or a resistance to its action. ADH regulates the reabsorption of water in the kidneys and prevents excessive urine output. Without enough ADH or with reduced sensitivity to it, the kidneys produce large amounts of diluted urine, leading to frequent urination and thirst. Chronic fatigue and mild confusion may result from dehydration and electrolyte imbalance. Serum glucose is not affected by diabetes insipidus, unlike diabetes mellitus, which is a disorder of carbohydrate metabolism.
