Question

1. Poor ventilation causes which of the following:
   • Respiratory acidosis
   • Hypocarbia
   • Hyperglycemia
   • None of the above
2. All of the following are causes of obstructive shock EXCEPT:
   • Congenital heart malformations
   • Tension pneumothorax
   • Cardiac tamponade
   • Acute blood loss
3. Which is a common cause of quiet tachypnea?
   • High fever
   • Hypoglycemia
   • Upper respiratory obstruction
   • None of the above
4. Which statement about sinus tachycardia is NOT correct?
   • Sinus tachycardia may occur in response to stress.
   • Sinus tachycardia may occur in response to fever.
   • Sinus tachycardia often indicates impending arrest.
   • Sinus tachycardia is a normal, non-dangerous rhythm.
5. A complete heart block is also known as:
   • Third degree AV block
   • Mobitz type II block
   • First degree AV block
   • Mobitz type I block
6. Which statement concerning cardioversion for unstable pediatric indviduals is NOT correct?
   • Cardioversion is indicated for wide complex tachycardia with poor perfusion.
   • Sedate them before cardioversion when possible, but do not delay cardioversion for sedation.
   • Cardioversion should not be done on pediatric indviduals under any circumstances.
   • Cardioversion is indicated for unstable ventricular tachycardia with a pulse.
7. Which of the following is a wide complex tachycardia?
   • Ventricular tachycardia
   • Sinus tachycardia
   • Supraventricular tachycardia
   • Atrial flutter
8. Common signs of compensated shock include:
   • Increased heart rate
   • Wide pulse pressure
   • Hypertension
   • Increased urine output
9. Which statement about tachycardia is NOT correct?
   • Sinus tachycardia is commonly a dangerous rhythm that can quickly deteriorate to cardiac arrest.
   • Tachycardia may be a normal, non-dangerous heart rate in response to stress or anxiety.
   • A heart rate of 175 bpm is within normal range for a child up to two
   • A normal heart rate for an infant may be twice as fast as a normal heart rate for an older child.
10. When should cardiac pacing be administered to an individual with symptomatic bradycardia with a pulse?
    • If the individual does not respond to CPR
    • If the individual does not respond to CPR and pharmacological support
    • None of the above
    • If the bradycardia is the result of a complete heart block or an abnormal sinus node function

Answer 1

1. The correct option is Respiratory acidosis .

It is a medical emergency in which decreased ventilation (hypoventilation) increases the concentration of carbon dioxide in the blood and decreases the blood's pH

2. The correct option is Congenital heart malformations .

Obstructive Shock is circulatory blockage, such as a large pulmonary embolus or cardiac tamponade, disrupts cardiac output (a big clog is now obstructing the heart, which may prevent it from being effective)

It is caused by PE, cardiac tamponade, tension pneumothorax, dissecting aortic aneurysm.

3. The correct option is High fever . High fever is the most common cause of quiet tachypnea

4. The correct option is - Sinus tachycardia often indicates impending arrest. Sinus tachycardia is the heart beat with normal rythm with heart rate more than 100bpm .

5. The correct option is - Third degree AV block . It is the complete heart block in which no electrical conductivity from artium to ventricles.

Answer 2

Respiratory acidosis
