What is the primary indication for Percutaneous Coronary Intervention (PCI)?
Chronic stable angina
Left main coronary artery disease
Unstable angina
Acute myocardial infarction (MI)
The Correct Answer is D
Rationale:
A. Chronic stable angina is incorrect because PCI may be considered for symptom relief in stable angina, but it is not the primary or emergent indication. Stable angina is usually managed first with lifestyle changes, medications (such as nitrates, beta-blockers, and calcium channel blockers), and risk factor modification.
B. Left main coronary artery disease is incorrect as a primary indication because significant left main disease often requires coronary artery bypass grafting (CABG) rather than PCI due to high risk of major adverse cardiac events. PCI may be used in select cases, but it is not the standard primary indication.
C. Unstable angina is partially correct because PCI can be performed in patients with unstable angina who have high-risk features; however, it is still not the primary emergent indication. Management may involve medications and risk stratification before intervention.
D. Acute myocardial infarction (MI) is correct because PCI is the first-line, time-sensitive intervention for patients experiencing an acute MI, especially STEMI (ST-elevation myocardial infarction). PCI restores blood flow to the occluded coronary artery, limits myocardial damage, reduces complications, and improves survival. Timely PCI is often referred to as “door-to-balloon” treatment and is the standard of care in acute coronary syndromes.

Correct Answer is D
Explanation
Rationale:
A. 25 kcal/kg/day – Partially correct but represents the lower end of the range and may not meet needs for all mildly stressed patients.
B. 30–35 kcal/kg/day – Incorrect for mild stress; this range is more appropriate for moderate to severe stress or hypermetabolic states.
C. 40 kcal/kg/day – excessive for mild stress and may contribute to overfeeding complications.
D. 25–30 kcal/kg/day – Caloric requirements for critically ill patients vary depending on the level of metabolic stress. Mildly stressed patients generally require 25–30 kcal/kg/day to maintain energy balance and support healing. This range accounts for the increased metabolic demands without overfeeding, which can lead to complications such as hyperglycemia or increased CO₂ production.
Correct Answer is D
Explanation
Rationale:
A. Confusion & bradycardia is incorrect. Confusion can occur in thyroid storm due to severe hypermetabolism affecting the CNS, but bradycardia is not consistent with the condition. Thyroid storm typically causes tachycardia or arrhythmias, not a slow heart rate.
B. Bradycardia & fever is incorrect. Fever is a key feature of thyroid storm, often greater than 101°F (38.3°C). However, bradycardia is opposite the expected hyperdynamic response. Patients usually have rapid heart rates, palpitations, and potential cardiovascular instability.
C. Tachycardia & weight gain is incorrect. Tachycardia is correct; patients with thyroid storm are hypermetabolic and frequently present with rapid heart rates. Weight gain is incorrect because hyperthyroidism increases metabolism, leading to weight loss even if appetite is increased.
D. Fever & tremors is correct. Both fever and tremors are classic signs of thyroid storm, reflecting hypermetabolism and sympathetic nervous system overactivity. Other associated signs include tachycardia, agitation, diaphoresis, confusion, and gastrointestinal symptoms. Early recognition is critical because thyroid storm is a life-threatening emergency requiring antithyroid therapy, beta-blockers, and supportive care.
