oxygen

A nurse is delivering 3 L/min oxygen to a client via nasal cannula. What percentage of delivered oxygen is the client receiving?

A nasal cannula is used to deliver from 1 L/minute to 6 L/minute of oxygen. 1 L/minute = 24%, 2 L/minute = 28%, 3 L/minute = 32%, 4 L/minute = 36%, 5 L/minute = 40%, and 6 L/minute = 44%

A nurse takes a client's pulse oximetry reading and finds that it is normal. What does this finding indicate?

The client's available hemoglobin is adequately saturated with oxygen Explanation: Pulse oximetry is a noninvasive technique that measures the arterial oxyhemoglobin saturation (SaO2 or SpO2) of arterial blood. This test measures only the percentage of oxygen carried by the available hemoglobin. Thus, even a client with a low hemoglobin level could appear to have a normal SpO2 because most of that hemoglobin is saturated. However, the client may not have enough oxygen to meet body needs. A normal pulse oximetry reading does not necessarily indicate a normal RBC count or heart rate.

The nurse is caring for a client who is receiving continuous oxygen at 3 L/minute via nasal cannula. The client's oxygen saturation has consistently been 94% to 96%, but suddenly drops to 86% as the nurse palpates the client's abdomen. The client denies respiratory difficulty or other distress. What is a likely reason for the client's decreasing oxygen saturation?

The nurse has inadvertently stepped on the client's oxygen tubing, occluding the flow of oxygen A sudden drop in oxygen saturation without clinical signs or symptoms may be caused by disruption of oxygen flow. The information in the question does not support a pulmonary embolism, the client holding his or her breath, or an appendix rupturing.

The nurse is talking with a client who has chronic obstructive pulmonary disease (COPD). The client reports chest shape seems to have changed over the past year. What information should be provided by the nurse?

"Your lung condition limits the ability of the lungs to fully exhale, causing this change in shape." In COPD, the client's chest becomes overinflated over time because of an inability to exhale fully. This increases the anterior-posterior chest diameter, resulting in a barrel-shaped appearance.

Upon auscultation of the client's lungs, the nurse hears loud, high-pitched sounds over the larynx. What term will the nurse use in documentation to describe this breath sound?

Bronchial breath sounds are loud, high-pitched sounds heard primarily over the trachea and larynx. Vesicular breath sounds are low-pitched, soft sounds heard over the peripheral lung fields. Bronchovesicular breath sounds are medium-pitched blowing sounds heard over the major bronchi. Vesicular, bronchial, and bronchovesicular breath sounds are normal breath sounds. Adventitious breath sounds are abnormal lung sounds.

Which teaching about the oxygen analyzer is important for the nurse to provide to a client using oxygen?

It determines whether the client is getting enough oxygen

To drain the apical sections of the upper lobes of the lungs, the nurse should place the client in which position?

high-Fowler's position Postural drainage makes use of gravity to drain secretions from the lungs from smaller pulmonary branches into larger ones, where they can be removed by coughing. High-Fowler's position is used to drain the apical sections of the upper lobes of the lungs. Placing the client lying on the left side with a pillow under the chest wall helps to drain the right lobe of the lung. Placing the client in a side-lying position, half on the abdomen and half on the side, right and left, helps to drain the posterior sections of the upper lobes of the lungs. Trendelenburg position assists in draining the lower lobes of the lungs

The pediatric nurse is caring for four clients. Which client will receive the greatest benefit from the use of an oxygen analyzer to assure that the client is receiving the prescribed amount of oxygen?

Croup tent An oxygen analyzer is used most commonly when caring for newborns in isolettes, children in croup tents, and clients who are mechanically ventilated. Other answers are incorrect

The nurse is caring for a client at risk for pneumonia after having major abdominal surgery. Which nursing instruction(s) is essential for the use of an incentive spirometer? Select all that apply.

Splint the abdomen with a pillow to decrease discomfort prior to use. Instruct the client to exhale normally and then place lips securely around the mouthpiece. Encourage the client to complete breathing exercises about 5 to 10 times every 1 to 2 hours, if possible. Assist the client to an upright or semi-Fowler position. Pain medication may be required prior to using a spirometer so that the client will be able to adequately perform the exercise. Another comfort measure that may be used is to place a folded blanket or pillow across the abdomen to create a splint while using the spirometer. The client should not breathe through the nose when using the spirometer. Place the client in an upright or semi-Fowler position to promote optimal gas exchange. The client should use the incentive spirometer 5 to 10 times every 1 to 2 hours for optimal results. Be sure that the client is instructed to exhale normally and place lips securely around the mouthpiece to obtain an airtight s

During data collection, the nurse auscultates low-pitched, soft sounds over the lungs' peripheral fields. Which appropriate terminology would the nurse use to describe these lung sounds when documenting?

Vesicular breath sounds are normal and described as low-pitched, soft sounds over the lungs' peripheral fields. Crackles are soft, high-pitched, discontinuous popping sounds heard on inspiration. Medium-pitched blowing sounds heard over the major bronchi describe bronchovesicular breath sounds. Bronchial breath sounds are loud, high-pitched sounds heard over the trachea and larynx.
