ch 5 & 6 self assessment questions

during bag/mask ventilation of a 70 kg patient, the therapist encounters a great deal of airflow resistance during inspiration. The therapist should select an oropharyngeal airway with a length that is equal to the distance from the:

center of the mouth to the angle of the jaw

A nasopharyngeal airway may be used as an airway adjunct in all of the following conditions except patients with:

epitaxis (nose bleed)

The normal size range of nasopharyngeal airway for adults ranges from:

6 to 8

An inward migration of a nasopharyngeal airway may be prevented by:

using a safety pin on the distal end of the nasopharyngeal airway

Since an esophageal obturator airway (EOA) is inserted into the ______, the cuff at the distal end must be _____ before providing manual ventilation.

esophagus, inflated

Since there are two ports on the mask of the _____, the manual resuscitation bag must be attached to the ventilation port of this airway.

esophageal gastric tube airway

The silicone-based laryngeal mask airway may be reused up to _____ times with proper handling and _____.

40, steam autoclaving

Since the cushioned mask of a laryngeal mask airway (LMA) provides a seal over the _____, it is not necessary for the LMA to enter the larynx or trachea

laryngeal opening

Which of the following is not true concerning the laryngeal mask airway (LMA)

LMA may withhold airway pressures up to 60 cm H2O

An esophageal-tracheal combitube (ETC) is inserted into the:

trachea or esophagus

Both lumens on the ETC can be used to provide ventilation. Lumen 1 is used when the tube enters the ______, and lumen 2 is used when it is in the _____,

esophagus, trachea

Following blind intubation with an ETC, ventilation should be attempted initially through lumen 1 of the ETC because:

an airway usually goes into the esophagus during blind intubation

Clinical conditions that may require independent lung ventilation include all of the following except:

respiratory distress syndrome

Following proper insertion and placement of a double-lumen endobronchial tube:

both cuffs are deflated

The decision to intubate a patient is based on all of the following indications with the exception of:

hypoxemia

Indication for using an artificial airway with relief of airway odstruction

epiglottitis

indication for using an artificial airway with protection of the airway

absence of coordinated swallow

indications for using an artificial airway with facilitation of suctioning

excessive secretions

indications for using an artificial airway with support of ventilation

ventilatory failure

The therapist is getting ready to intubate a patient who has been classified as Class 3 using the Mallampati method. The therapist should _____ because the _____ are seen during assessment.

seek anesthesia consultation, soft palate and base of uvula

A therapist is preparing to intubate a 49 year old, 60 kg (132 lb) patient, and two endotracheal tubes, size 7 and size 8 are available. The therapist should be use the _______ tube because it offers ______ than the other ET tube.

size 8, lower airflow resistance

The therapist is performing an elective intubation on a 32 year old, 78 kg (172 lb) 5 ft 2 in. patient in the ICU. Based on the patients physical characteristics, the therapist should use the size ______, _______ laryngoscope blade.

3, miller

When the therapist intubates the patient in the preceding question, the therapist should place the tip of the blade just under the ________ and use the laryngoscope handle to ______.

epiglottis, lift up anteriorly

During intubation of an apneic patient, the patient develops arrhythmias. The therapist should remove the blade and endotracheal tube immediately and provide:

100% oxygen via manual resuscitation bag/mask system

The best approach to avoid esophageal intubation is to ensure that the endotracheal tube goes through the ______ under direct vision.

vocal cords

trauma done to the teeth of a patient undergoing an intubation procedure is most likely caused by using:

pivoting action to lift the blade and tongue

After intubating a spontaneously breathing 40 kg (88 lb) patient, all of the following signs may be used to assess correct placement of the endotracheal tube except:

presence of breath sounds at the sternum.

The onset time for etomidate and succinylcholine used in rapid sequence intubation is about ______ min and these drugs last about ______ min.

1, 5

In order to avoid mucosal injuries of the trachea, the cuff of an endotracheal tube may be managed by any one of the following techniques except:

periodic deflation for 20 minutes q 4

A speaking valve attached to a cuffed tracheostomy tube does not allow the patient to _______ through the valve. For this reason, the cuff must be _______.

exhale, deflated

A patient develops bradycardia during an intubation attempt. The therapist should stop intubation immediately and ______ the patient since this condition is likely caused by ________.

rest, vagal stimulation
