All are true in anemia except.

Correct Answer: C

Rationale: Thalassemia patients may require iron if deficient (e.g., from blood loss), though iron overload is a concern in transfusion-dependent cases. The absolute 'never' is incorrect. Other statements align with anemia pathophysiology.

Correct Answer: A

Rationale: Home blood pressure monitoring provides a more accurate reflection of overall cardiovascular risk compared to sporadic office readings and avoids white-coat effects.

Correct Answer: D

Rationale: Cholesterol crystals in synovial fluid are a normal finding in chronic joint effusions, such as in rheumatoid arthritis or osteoarthritis, rather than a specific disease like hyperlipidemia.

Correct Answer: C

Rationale: Preload reduces glomerular filtration resulting in fluid conservation, or edema. Increased preload may lead to an increased, not decreased, heart rate. Increased preload may lead to shortness of breath and an increased respiratory rate. Increased preload may lead to fatigue, not excitability, as the heart works harder to circulate blood.

Correct Answer: D

Rationale: ACE inhibitors (D) reduce workload, promote sodium excretion, and commonly cause a cough due to bradykinin buildup.
