PALS Final Exam Version 1
### 1. A 12-year-old child being evaluated in the pediatric intensive
care unit displays the following ECG waveform. The team interprets
this as which arrhythmia?
Answer: Second degree AV block
Choices:
A. First-degree AV block
B. Second-degree AV block
C.Third-degree AV block
D.Supraventricular tachycardia (SVT)
CORRECT ANSWER>> B. Second-degree AV block
Expert logic>>
Second-degree AV block is characterized by intermittent failure of
conduction between the atria and ventricles, seen on ECG as dropped
QRS complexes without progression of PR interval lengthening (Type II) or
progressive PR elongation followed by a dropped beat (Type I). PALS
providers must recognize this rhythm due to its potential to progress and
cause hemodynamic compromise, guiding appropriate intervention such as
close monitoring or pacing.

### 2. Laboratory tests are ordered for a child who has been vomiting
for 3 days and is diaphoretic, tachypneic, lethargic and pale. Which
test would the provider use to determine the adequacy of oxygen
delivery?
Choices:
A. Complete blood count (CBC)
B. Serum bicarbonate
C.Blood lactate
D.Blood glucose
CORRECT ANSWER>> C. Blood lactate
Expert logic>>
Blood lactate is a sensitive marker of tissue hypoxia and inadequate
oxygen delivery. Elevated lactate indicates anaerobic metabolism, as seen
in shock states or severe dehydration. PALS providers use lactate to
assess shock severity and guide fluid resuscitation and oxygen therapy.
Other tests (CBC, bicarbonate, glucose) provide supportive info but do not
directly measure oxygen delivery adequacy.

### 3. A 9-year-old patient is presenting with decreased breath
sounds, bradycardia, slowed respiratory rate, and a low O2 saturation
level. The provider interprets these findings as indicating which
condition?
Choices:
, A. Respiratory distress
B. Respiratory failure
C. Respiratory arrest
D. Asthma exacerbation
CORRECT ANSWER>> B. Respiratory failure
Expert logic>>
Respiratory failure is characterized by inadequate ventilation and
oxygenation, leading to hypoxia and hypercapnia. Signs include
bradycardia (a late sign in hypoxia), depressed respiratory rates, poor
breath sounds, and hypoxemia. Recognizing respiratory failure is critical in
PALS to initiate airway management and prevent cardiac arrest.

### 4. A 4-year-old child is brought to the emergency department by
the parents. Assessment reveals that the child has only gasping
respirations and the pulse rate is 65 beats per minute. Which action
would the provider initiate first?
Choices:
A. Start chest compressions immediately
B. Deliver 1 BVM ventilation every 3 to 5 seconds
C. Administer oxygen by nasal cannula
D. Apply cardiac monitor
CORRECT ANSWER>> B. Deliver 1 BVM ventilation every 3 to 5 seconds
Expert logic>>
