Cuff pressure for an endotracheal tube should be maintained at _____ mm Hg and should be checked every _______ hours.

15 and 20, and 3 to 8 hrs

The water seal used in a disposable chest drainage system is effective if the water seal chamber is filled to the level of ______ cm H2O.

2 cm

Oxygen toxicity may occur when oxygen concentration at greater than ____% is given for ________. (length of time)

50, >48 hrs

A pt with COPD requires oxygen administration. What method of delivery does the nurse know would produce optimal results for this pt ?

A Venturi Mask

In many pts with _________, the stimulus for respiration is a Decrease in blood oxygen rather than an elevation in carbon dioxide levels.

COPD

The nurse is transporting a patient with chest tubes to a treatment room. The chest tube becomes disconnected and falls between the bed rail. What is the priority action by the nurse?

Cut the contaminated tip of the tube and insert a sterile connector and reattach.

The nurse is educating the pt in the use of a mini-nebulizer. What should the nurse encourage the pt. to do?

Hold breath at the end of inspiration, Cough Frequently, Frequently evaluate progress

Decrease in oxygen supply to the TISSUES

Hypoxia

Explain how Positive pressure ventilators work;

Inflate the lungs by exerting pressure on the airway, pushing air in, FORCING the alveoli to expand during inspiration

Low-flow oxygen delivery systems:

Nasal Cannula, oropharyngeal catheter, simple mask, partial rebreather, nonrebreather

The nurse is assessing a pt. with chest tubes connected to a drainage system. What should the first action be when the nurse observes excessive bubbling in the water seal chamber?

Notify the Healthcare provider

A pt with emphysema is placed on continuous oxygen at 2 L/min at home. Why is it important for the nurse to educate the pt and family that they must have NO SMOKING signs placed on the doors?

Oxygen supports combustion

A pt has been receiving 100% oxygen therapy by way of a nonrebreather mask for several days. Now the pt reports tingling in the fingers and SOB, is extremely restless, and describes a pain beneath the breastbone. What condition should the nurse suspect?

Oxygen toxicity

A pt. in the process of being weaned from the ventilator will have a _________ connected to the endotracheal tube.

T-piece

Antioxidants such as ___________, ____________, and ___________ may help defend against oxygen-free radicals.

Vitamin E, Vitamin C, beta carotene

A pt. is to receive an oxygen concentration of 70%. What is the best way for the nurse to deliver this concentration?

a partial rebreathing mask

Assessments findings determine oxygen toxicity:

dyspnea, restlessness, fatigue, substernal discomfort, paresthesias, malaise, progressive respiratory difficulty, refractory hypoxemia, alveolar atelectasis, alveolar infiltrates on x-ray

What function does bilevel positive airway pressure (bi-PAP) ventilation serve for the pt?

independent control of inspiratory and expiratory pressures while providing support ventilation.

The term used to describe thoracic surgery in which an entire lung is removed is known as:

pneumonectomy
