Preload refers to:
a. The volume of blood entering the left side of the heart
b. The volume of blood entering the right side of the heart
c. The pressure in the venous system that the heart must overcome to pump the blood
d. The pressure in the arterial system that the heart must overcome to pump the blood ✔️✔️b.
Preload is the volume of blood that enters the right side of the heart. This volume stretches the fibers in
the heart prior to contraction. Preload is commonly measured as atrial pressure.
What is the first intervention for a patient with a suspected stroke who presents within the therapeutic
window?
The first intervention is to obtain a non-contrast CT scan or MRI to differentiate between ischemic and
hemorrhagic stroke, followed by initiating thrombolytic therapy if the patient is eligible for treatment.
✔️✔️
What are the signs of a ruptured abdominal aortic aneurysm (AAA)?
Signs include sudden, severe abdominal or back pain, hypotension, tachycardia, and a pulsatile
abdominal mass. Immediate surgery may be required to repair the rupture. ✔️✔️
How do you manage a patient who presents with a third-degree burn?
Management includes ensuring airway protection, fluid resuscitation using the Parkland formula, and
covering the burn with sterile dressings to prevent infection while preparing the patient for potential
surgical intervention. ✔️✔️
What is the priority intervention for a patient with a suspected myocardial infarction (MI) and ST-
segment elevation on an ECG?
, The priority is to administer aspirin to reduce platelet aggregation, provide oxygen, and prepare for
immediate reperfusion therapy (e.g., thrombolytics or percutaneous coronary intervention) to restore
blood flow to the heart. ✔️✔️
How should you manage a patient with a heat stroke?
Immediate cooling measures such as applying ice packs, using cooling blankets, and administering IV
fluids should be initiated to reduce body temperature and prevent organ damage. Close monitoring of
vital signs and renal function is critical. ✔️✔️
What is the first step in managing a patient with an obstructed airway due to a foreign body?
For an adult or child over 1 year, perform the Heimlich maneuver to expel the foreign body. For infants,
use back blows and chest thrusts to clear the airway. ✔️✔️
What is the most important factor in the early management of a patient with an overdose of
benzodiazepines?
The most important factor is ensuring airway patency and providing respiratory support, followed by
administering flumazenil (if indicated) to reverse the sedative effects of benzodiazepines. ✔️✔️
What is the priority when managing a patient with a penetrating trauma to the chest?
The priority is to prevent air from entering the chest cavity by covering the wound with a sterile, airtight
dressing, followed by assessing for signs of tension pneumothorax or cardiac tamponade. ✔️✔️
What is the first intervention for a patient with an acute exacerbation of chronic obstructive pulmonary
disease (COPD)?
The first intervention is to administer a short-acting bronchodilator such as albuterol, provide oxygen
therapy to maintain oxygen saturation, and assess the patient’s response to treatment. ✔️✔️
