Which condition can lead to decreased urine output (oliguria)?
Diabetes mellitus
Hypertension
Dehydration
Increased fluid intake
The Correct Answer is C
A. Diabetes mellitus: Diabetes mellitus primarily causes excessive urine output (polyuria) due to osmotic diuresis from high blood glucose levels. It does not typically lead to decreased urine output unless there is severe dehydration or kidney involvement.
B. Hypertension: Chronic hypertension can damage the kidneys over time, potentially reducing urine output, but in the early stages, it does not usually cause oliguria. Acute blood pressure changes may indirectly affect kidney perfusion.
C. Dehydration: Dehydration reduces the body’s fluid volume, leading to decreased kidney perfusion and a subsequent reduction in urine output. Oliguria is a common compensatory response to conserve water and maintain fluid balance.
D. Increased fluid intake: Increased fluid intake typically results in increased urine output (polyuria), not decreased output. The kidneys respond to excess fluids by excreting more urine to maintain homeostasis.

Correct Answer is B
Explanation
A. Cardiac muscle: Cardiac muscle is found only in the heart and contracts involuntarily to pump blood. While it shares some involuntary characteristics with smooth muscle, it is specialized for rhythmic contraction and is not present in the walls of other internal organs.
B. Smooth muscle: Smooth muscle is found in the walls of internal organs such as the stomach, intestines, and blood vessels. It functions involuntarily, controlling movements like peristalsis and vessel constriction without conscious effort, making it essential for organ function.
C. Striated muscle: Striated muscle refers to muscle with a striped appearance, including both skeletal and cardiac muscle. Striated muscle does not describe smooth muscle and is not primarily involved in involuntary movements of internal organs.
D. Skeletal muscle: Skeletal muscle is under voluntary control and is attached to bones to facilitate movement. It is not found in internal organs and does not function automatically, distinguishing it from smooth muscle.
Correct Answer is C
Explanation
A. Cardiac muscle: Cardiac muscle is involuntary and found only in the heart. It contracts automatically to pump blood and cannot be consciously controlled, so it does not contribute to voluntary movements.
B. Smooth muscle: Smooth muscle is also involuntary and is found in the walls of internal organs such as the intestines, blood vessels, and bladder. Its contractions are automatic and not under conscious control.
C. Skeletal muscle: Skeletal muscle is under voluntary control and is attached to bones via tendons. Contraction of skeletal muscles allows deliberate movements such as walking, lifting, and writing, making it responsible for voluntary actions.
D. Striated smooth muscle: Striated smooth muscle is not a recognized type of muscle tissue. Striated muscles refer to skeletal and cardiac muscle, whereas smooth muscle is non-striated and involuntary.
