Question 1

In the lateral position, blood flow to the dependent lung of the anesthetized patient MOST represents which zone of flow?

Accepted Answer

Zone: 3

Answer

Explanation:
Zone 3 occurs in dependent lung regions where alveolar pressure exceeds arterial and venous pressures. This positioning allows for optimal gas exchange in these areas, which are crucial for maintaining adequate ventilation and perfusion balance during anesthesia.

Question 2

Calculate the cardiac output given the following hemodynamic parameters:

Stroke volume: 60 mL
Blood pressure: 150/70 mm Hg
Heart rate: 50/min

Accepted Answer

3 L/min

Answer

Explanation:
To calculate cardiac output (CO), you can use the formula:
CO = Stroke Volume × Heart Rate

Given:
Stroke Volume (SV) = 60 mL
Heart Rate (HR) = 50 beats per minute

First, calculate the cardiac output in mL/min:
CO = 60 mL × 50 beats/min
CO = 3000 mL/min

Now, convert mL/min to L/min (since 1 L = 1000 mL): CO = 3 L/min

Question 3

What is the hourly maintenance fluid rate for an 11-pound infant?

Accepted Answer

20 mL/h

Answer

Explanation:
The hourly maintenance fluid rate for an 11-pound infant is typically calculated using the Holliday-Segar method, which suggests a rate of approximately 4 mL/kg/hour for the first 10 kg of body weight.
For an 11-pound infant (approximately 5 kg):
4 mL/kg/hour × 5 kg = 20 mL/hour

Question 4

Considerations for the management of a patient with myotonic dystrophy under general anesthesia should include a/an:

Accepted Answer

short-acting nondepolarizer.

Answer

Explanation:
Myotonic dystrophy is a genetic disorder affecting muscle function, and patients may be sensitive to depolarizing muscle relaxants like succinylcholine. Therefore, using a short-acting nondepolarizing muscle relaxant is preferred to avoid complications associated with prolonged neuromuscular blockade in these patients.

Question 5

Which neuromuscular blocking agent is a benzylisoquinoline compound?

Accepted Answer

Mivacurium

Answer

Explanation:
Mivacurium is a neuromuscular blocking agent that belongs to the benzylisoquinoline class of compounds. It is a short-acting nondepolarizing muscle relaxant used in anesthesia.
