Critical care

Pericardial tamponade falls under which type of shock?

• Hypovolemic shock

• Distributive shock

• Obstructive shock

• Cardiogenic shock

A patient with findings of bradycardia, hypertension and altered breathing is considered life threatening and must be evaluated properly in the emergency department. These findings can be due to

• Increased intracranial pressure

• Intracranial hemorrhage

• Acute nerve injury

• Migraine variant

Presence of carbon monoxide poisoning results to which of the following?

• Shifting of oxyhemoglobin dissociation curve to the right

• Shifting of oxyhemoglobin dissociation curve to the left

• Causes increased delivery of oxygen to the tissues

• Decreases the oxygen affinity of the remaining 3 oxygen-binding sites

Toddlers who present with difficulty of breathing after a coughing or choking episode must be evaluated for foreign body aspiration. Ingestion of this particular substance is considered a true medical emergency that warrants In immediate endoscopic removal.

• Coin

• Button battery

• Marble

• Food chunks

A patient was admitted at the ER for severe cardiorespiratory distress with associated decreased breath sounds, dullness on percussion of the chest, midline tracheal location, flat neck veins but with normal heart tones. What is your diagnosis?

• Tension pneumothorax

• Massive hemothorax

• Cardiac tamponade

• Atelectasis

The most common precipitating event for cardiac instability in infants and children is

• Loss of consciousness

• Seizure

• Respiratory insufficiency

• Hypotension

Cardiovascular function is assessed by the evaluation of the following

• blood pressure

• pulse rate and rhythm

• skin color, temperature, heart rate/rhythm, pulses, capillary refill time

• pulses, capillary refill time, blood pressure

The first response to unwitnessed unresponsive infant is to:

• Activate emergency response system

• Check pulse

• Start rescue breathing

• Start chest compression

The most common cause of shock worldwide:

• Obstructive shock

• Septic shock

• Hypovolemic shock

• Cardiogenic shock

Septic shock usually shows a combination of hypovolemic and distributive shock in addition to:

• Obstructive shock

• Cardiogenic shock

• Acute respiratory distress syndrome

• Disseminated intravascular coaagulation
