Question 1

To avoid hypoxia, how long should a pediatric patient be suctioned?

Accepted Answer

To avoid hypoxia, a pediatric patient should be suctioned from 5-10 seconds. As with an adult, an infant needs suctioning if there is an airway occlusion and there are no dangers of inherent hypoxemia as long as the skill is done correctly. However, care should still be taken to avoid hypoxemia by not suctioning for longer than 10 seconds and only suctioning while withdrawing the catheter.

Question 2

To avoid hypoxia, how long should a patient be suctioned?

Accepted Answer

The EMT-P should limit their airway suctioning attempts to not more than 15 seconds. Suctioning longer can result in hypoxia and can make the patient worse.

Question 3

When auscultating the lung(s) in areas of a tension pneumothorax, which of the following lung sounds are likely to be heard?

Accepted Answer

In the region of a pneumothorax, there will be a decrease or absence of breath sounds due to the collapse in the lung at that particular region. Therefore, there will be little or no sound present.

Question 4

Which of the following signs and symptoms is not present in a tension pneumothorax?

Accepted Answer

Hypertension will not occur when breathing is labored. The blood pressure will lower (hypotension) in the case of a tension pneumothorax secondary to increase pressure on the heart.

Question 5

Pulmonary embolism is caused by a blood clot or some other particle that lodges in the pulmonary artery. What factor can make an individual predisposed to this condition?

Accepted Answer

Prolonged immobilization, thrombophlebitis, and atrial fibrillation all can make an individual predisposed to pulmonary embolism; certain medications can also. This condition is potentially life threatening because it can significantly decrease pulmonary blood flow, thus leading to hypoxemia. The problem occurs when a blood clot travels up the venous circulatory system and lodges in a pulmonary artery.
