Question 1

Which vasopressor is recommended as first-line therapy for septic shock refractory to fluid resuscitation?

Accepted Answer

Norepinephrine

Answer

Norepinephrine is the first-line vasopressor for septic shock due to its potent alpha-adrenergic vasoconstriction with minimal tachycardia compared to alternatives.

Question 2

In the management of anaphylaxis, which is the most important first-line drug and route of administration?

Accepted Answer

IM epinephrine 0.5 mg (1:1000)

Answer

Intramuscular epinephrine (adrenaline) 0.5 mg of 1:1000 solution into the anterolateral thigh is the cornerstone of anaphylaxis treatment, reversing bronchospasm and vasodilation.

Question 3

What is the recommended compression-to-ventilation ratio in adult CPR for a single rescuer?

Accepted Answer

30:2

Answer

The 2020 AHA guidelines recommend a 30:2 compression-to-ventilation ratio for adult CPR with a single rescuer, prioritizing chest compressions.

Question 4

Which acid-base disturbance is most commonly seen in early septic shock?

Accepted Answer

High anion gap metabolic acidosis

Answer

High anion gap metabolic acidosis from lactic acidosis is the most common acid-base abnormality in early septic shock due to tissue hypoperfusion and anaerobic metabolism.

Question 5

What is the target mean arterial pressure (MAP) recommended in the Surviving Sepsis Campaign for septic shock?

Accepted Answer

65 mmHg

Answer

The Surviving Sepsis Campaign recommends a target MAP of ≥65 mmHg as the initial resuscitation goal in adults with septic shock.
