Question 1

Immediate management of an unconscious patient includes:&#10;A)placement on the floor of the treatment room&#10;B)administration of oxygen-enriched air&#10;C)administration of 100% oxygen&#10;D)placement in the supine position

Accepted Answer

placement in the supine position

Question 2

The primary cause of airway obstruction is:&#10;A)constriction of smooth muscle of bronchioles&#10;B)the tongue falling into the hypopharynx as skeletal muscle tone is lost&#10;C)rebound nasal swelling&#10;D)muscular hypertrophy

Accepted Answer

The primary cause of airway obstruction, especially in unconscious or anesthetized patients, is the tongue falling into the hypopharynx as skeletal muscle tone is lost. This can block the airway, making it difficult for air to reach the lungs.

Question 3

The patient's vital signs of blood pressure,pulse,and respiratory rate should be measured every:&#10;A)1 minute&#10;B)5 minutes&#10;C)15 minutes&#10;D)30 minutes

Accepted Answer

5 minutes

Question 4

Normal PaCO₂is _______ torr. A)15 to 30 B)35 to 45 C)50 to 75 D)75 to 100

Accepted Answer

Normal PaCO2 (partial pressure of carbon dioxide in arterial blood) ranges from 35 to 45 torr.

Question 5

Immediate management of a conscious patient who experiences respiratory difficulty includes:&#10;A)administration of oxygen-enriched air&#10;B)administration of 100% oxygen&#10;C)placement in the most comfortable position&#10;D)placement in the supine position with feet horizontal&#10;E)placement in the supine position with feet elevated slightly

Accepted Answer

The answer of Immediate management of a conscious patient who...

Question 6

A torr is a unit of:&#10;A)tension equal to 1 mm Hg&#10;B)tension equal to 10 mm Hg&#10;C)pressure equal to 1 mm Hg&#10;D)pressure equal to 10 mm Hg

Accepted Answer

A torr is a unit of pressure equal to 1 mm Hg. It is often used in vacuum measurements and is equivalent to other common pressure units such as the millibar and the atmosphere.

Question 7

If a foreign object becomes impacted in the ________,total airway obstruction ensues,a life-threatening situation.&#10;A)right main-stem bronchus&#10;B)left main-stem bronchus&#10;C)trachea&#10;D)larynx

Accepted Answer

The trachea is the main airway that leads to the lungs. If a foreign object becomes impacted in the trachea, it will block off the airway completely and result in total airway obstruction. This is a life-threatening situation and requires immediate medical attention. The right and left main-stem bronchi are smaller branches of the trachea that lead to the lungs, but blockage in these areas may not necessarily result in total airway obstruction. The larynx, or voice box, is located above the trachea and is responsible for sound production. While blockage in this area can cause difficulty breathing, it is not typically as life-threatening as complete obstruction of the trachea.

Question 8

Bronchioles are the primary site of:&#10;A)asthma&#10;B)congestive heart failure&#10;C)hyperventilation&#10;D)acute lower-airway obstruction

Accepted Answer

Bronchioles are the primary site of asthma, which is a condition characterized by inflammation and narrowing of the airways.

Question 9

The rapid breathing associated with hyperventilation results in elimination of an excessive amount of ___________,leading to the development of respiratory _________.&#10;A)oxygen;acidosis&#10;B)oxygen;alkalosis&#10;C)carbon dioxide;acidosis&#10;D)carbon dioxide;alkalosis

Accepted Answer

Hyperventilation leads to elimination of excessive carbon dioxide, resulting in a decrease in carbonic acid in the blood, leading to respiratory alkalosis.

Question 10

Bronchospasm is associated with:&#10;A)hyperventilation&#10;B)hypoventilation&#10;C)asthma&#10;D)pulmonary edema

Accepted Answer

Bronchospasm is a condition where the smooth muscles of the bronchioles in the lungs contract, leading to difficulty breathing. This condition is commonly associated with asthma. Hyperventilation and hypoventilation are not directly associated with bronchospasm, and pulmonary edema may cause shortness of breath and difficulty breathing, but it is not necessarily associated with bronchospasm.

Question 11

Apnea is defined as:&#10;A)a subjective sense of shortness of breath&#10;B)absence of respiratory movement&#10;C)greater than normal per-minute ventilation&#10;D)inability to breathe except in the upright position

Accepted Answer

The answer of Apnea is defined as:&#10;A)a subjective sense of...
