Respiratory

The nurse clarifies that the condition in which there is a decreased amount of oxygen in the blood is:

• • dyspnea.

• • hypoxemia.

• • hypercapnia.

• • hypoxia.

The nurse uses a diagram to show that when the diaphragm moves:

• • up, the decreased negative pressure allows air to enter the lungs.

• • down, the negative pressure in the thoracic space pulls air into the lungs.

• • down, the intercostal muscles retract, forcing air out of the lungs.

• • up, the increased negative pressure in the thoracic space forces air into the lungs.

The nurse monitoring patients eating in the dining room of a skilled nursing facility notes that a patient begins choking. As the nurse prepares to deliver the Heimlich maneuver, the fist should be positioned:

• • directly over the umbilicus.

• directly over the sternum.

• • between the umbilicus and the symphysis pubis.

• • halfway between the xiphoid process and the umbilicus.

The nurse instructing the patient to perform forceful exhalation coughing would instruct the patient to take in:

• • two breaths and force the air out quickly.

• • two deep breaths, then inhale deeply again and force out the air quickly.

• • one breath, hold it for 3 seconds, then forcefully exhale three times with mouth open.

• • one deep breath and quickly exhale.

A patient who will begin oxygen therapy has a history of sinus disorders. This patient would benefit most from which oxygen setup?

• • A nasal cannula

• • A humidifier

• • A Venturi mask

• • High oxygen flow rate

A patient has a history of chronic obstructive pulmonary disease. The patient’s oxygen flow rate should be set to no more than:

• • 2 to 3 L/min.

• • 1 to 2 L/min.

• • 4 to 5 L/min.

• • 5 to 10 L/min.

The nurse loosens mucus plugs by using percussion on a patient over the area of the:

• • spine between the scapulae.

• • midaxillary line on the rib cage.

• • thorax.

• • sternum.

The nurse recognizes that a postoperative patient who can breathe independently but has trouble maintaining an airway because of the tongue falling back into the throat would be best benefitted by a(n):

• • partial rebreather oxygen mask.

• • pharyngeal airway.

• • tracheostomy.

• • endotracheal tube.

A nurse performing oral suctioning on an adult patient should set the wall suction machine so that the suction pressure is between:

• • 80 and 120 mm Hg.

• • 25 and 50 mm Hg.

• • 50 and 75 mm Hg.

• • 120 and 180 mm Hg.

The nurse takes into consideration that while caring for a patient on oxygen therapy, safety precautions should be observed, which include:

• • assessing equipment in room for frayed cords.

• • reducing humidification on the oxygen delivery device.

• • removing any adhesive from the patient’s skin with acetone.

• • using clothing of synthetic cloth for the patient.
