Chapter 39: Oxygenation and Perfusion

Which skin disorder is associated with asthma?

eczema

A client has edema of the feet and ankles, along with crackles in the lower lobes and a frothy, productive cough. The client is suffering from:

congestive heart failure

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. The oxygen analyzer measures the percentage of delivered oxygen to determine whether the client is receiving the prescribed amount. The flowmeter is a gauge used to regulate the amount of oxygen that a client receives. The provider prescribes concentration. The humidifier produces small water droplets that are delivered during oxygen administration to decrease dry mucous membranes.

An older adult client is visibly pale with a respiratory rate of 30 breaths per minute. Upon questioning, the client states to the nurse, "I can't seem to catch my breath." The nurse has responded by repositioning the client and measuring the client's oxygen saturation using pulse oximetry, yielding a reading of 90%. The nurse should interpret this oxygen saturation reading in light of the client's:

hemoglobin level Pulse oximetry readings are reflective of the number of available oxygen receptors on hemoglobin molecules. Consequently, an acceptable reading in a client with low hemoglobin can be artificially inflated. Age, blood pH, and electrolyte levels do not have a direct bearing on the accuracy and clinical application of pulse oximetry.

The nurse is applying a pulse oximeter to a client with bronchitis. Which factor does the nurse communicate to the client that could interfere with accurate pulse oximetry?

When reviewing data collection on a client with a cardiac output of 2.5 L/minute, the nurse inspects the client for which symptom?

Rapid respirations Normal cardiac output averages from 3.5 L/minute to 8.0 L/minute. With decreased cardiac output, there is a reduction in the amount of circulating blood that is available to deliver oxygen to the tissues. The body compensates by increasing respiratory rate to increase oxygen delivery to the tissues. The client with decreased cardiac output would gain weight, have decreased urine output, and display mental confusion.

When inspecting a client's chest to assess respiratory status, the nurse should be aware of which normal finding?

The chest should be slightly convex with no sternal depression. The adult chest contour is slightly convex, with no sternal depression. The skin of the thorax should be warm and dry, and the anteroposterior diameter of the chest should be less than the transverse diameter. The contour of the intercostal spaces should be flat or depressed.

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.

A nurse suctioning a client through a tracheostomy tube should be careful not to occlude the Y-port when inserting the suction catheter because it would cause what condition to occur?

trauma to the tracheal mucosa Occluding the Y-port on the suction tubing is what creates the suction. While suctioning would be difficult but possible, suctioning while advancing the tube would damage the tracheal mucosa and remove excessive amounts of oxygen, not carbon dioxide, from the respiratory tract. Suctioning during insertion of the catheter would not compromise sterility.
