Question 1

Which of the following is the correct sequence of steps for safely assembling an oxygen tank and regulator?

Accepted Answer

Keep the tank closed, attach the regulator, tighten securely, then open the tank valve and check the pressure gauge.

Question 2

A patient requires oxygen via nasal cannula. Which of the following is the correct method for administering oxygen using this device?

Accepted Answer

Attach the cannula to the flow meter, select a flow rate of 1-6 LPM, and place the cannula in the patient's nostrils.

Question 3

When using a non-rebreather mask to deliver oxygen, which of the following steps is essential for proper function?

Accepted Answer

Select a flow rate of 10-15 LPM, fill the reservoir bag with oxygen, and ensure a tight mask fit.

Question 4

A patient is unresponsive with agonal respirations. Which airway adjunct is most appropriate to use if there is no evidence of C-spine injury and no gag reflex?

Accepted Answer

Oropharyngeal airway (OPA)

Question 5

When sizing an oropharyngeal airway (OPA), what is the correct anatomical measurement to use?

Accepted Answer

From the corner of the mouth to the angle of the jaw

Question 6

Which of the following is the correct method for inserting a nasopharyngeal airway (NPA)?

Accepted Answer

Insert the lubricated NPA with the bevel facing the septum, following the natural curvature of the nasal passage.

Question 7

When using a bag-valve-mask (BVM) to ventilate a non-breathing patient, which of the following best describes the correct technique?

Accepted Answer

Deliver breaths every 5-6 seconds, ensuring visible chest rise, and use the E-C clamp technique to hold the mask.

Question 8

What is the maximum recommended suction time for an adult patient using a rigid suction catheter?

Accepted Answer

$$15$$ seconds

Question 9

A child requires suctioning of the pharynx. What is the maximum recommended suction time for a child?

Accepted Answer

$$10$$ seconds

Question 10

Which of the following best describes the correct method for suctioning the pharynx with a rigid catheter?

Accepted Answer

Insert the catheter without suction, apply suction only while withdrawing, and limit suction time to the recommended maximum.

Question 11

A patient has been intubated with an endotracheal tube. Which of the following is a critical step before ventilating the patient?

Accepted Answer

Inflate the cuff and verify tube placement by auscultating the chest and epigastrium.

Question 12

Which of the following is the correct formula for calculating the minute ventilation ($$V_E) $$delivered to a patient using a BVM?

Accepted Answer

$$V_E = V_T 	imes f$$

Question 13

During oxygen tank assembly, why is it important to open the tank valve slowly?

Accepted Answer

To prevent rapid pressurization that could damage the regulator or cause injury.

Question 14

A patient with a suspected cervical spine injury requires airway management. Which airway adjunct is preferred?

Accepted Answer

Nasopharyngeal airway (NPA)

Question 15

Which of the following is a sign that a non-rebreather mask is functioning properly?

Accepted Answer

The reservoir bag inflates with oxygen before application and does not collapse completely during inhalation.

Question 16

When ventilating a patient with a BVM, which of the following best ensures an adequate seal and effective ventilation?

Accepted Answer

Using the E-C clamp technique with one hand while squeezing the bag with the other.

Question 17

Which of the following is a critical safety step when preparing to suction a patient's airway?

Accepted Answer

Check the catheter for presence or absence of opening that must be covered to initiate suction.

Question 18

A patient is being ventilated with a BVM after intubation. What is the most reliable method to confirm correct endotracheal tube placement?

Accepted Answer

Observing for bilateral chest rise and auscultating both lungs and the epigastrium.

Question 19

Which of the following is the correct formula for determining the appropriate size of an oropharyngeal airway (OPA)?

Accepted Answer

$$	ext{OPA size} = 	ext{distance from corner of mouth to angle of jaw}$$
