Correct Answer is A

Explanation

A. Blood flow starts from the right atrium, moves into the right ventricle, then to the lungs, where it is oxygenated and returns to the left atrium, and then flows into the left ventricle before being pumped into the aorta.
B. This sequence incorrectly places the left atrium before the right ventricle, which is not the correct flow of blood.
C. This sequence starts incorrectly with the right ventricle, skipping the left atrium entirely after blood is oxygenated.
D. This option also incorrectly starts with the right ventricle and does not include the proper sequence of blood flow.

A. Weak quadriceps muscles B. Decreased deep tendon reflexes C. Tingling of extremities with possible tetany D. Light-headedness when standing up

Correct Answer is C

Explanation

A. Weak quadriceps muscles can occur with electrolyte imbalances, but the provided values do not indicate hypokalemia or other issues causing muscle weakness.
B. Decreased deep tendon reflexes are generally associated with elevated calcium levels or other electrolyte disturbances but are not specifically indicated by the given lab values.
C. A calcium level of 4.5 mg/dL is significantly low (normal range is typically around 8.5-10.5 mg/dL), which can lead to hypocalcemia symptoms such as tingling of the extremities and tetany due to increased neuromuscular excitability.
D. Light-headedness when standing up (orthostatic hypotension) is more related to fluid volume status or dehydration rather than directly related to the given electrolyte levels.
