Answer to Question 1
B
When caring for a client using oxygen, the nurse needs to minimize the chances of initiating sparks that can lead to the combustion of the oxygen. Cotton or acrylic blankets, rather than wool, should be used on the client's bed.
Answer to Question 2
B
A regular interval interrupted by an early beat, late beat, or a missed beat indicates an abnormal rhythm or dysrhythmia. A dysrhythmia alters cardiac function, particularly if it occurs repeti-tively. If your patient has a dysrhythmia you need to assess how often it is occurring. After prop-erly positioning the bell or the diaphragm of the stethoscope on the chest, try to identify the first and second heart sounds (S1 and S2). At normal slow rates, S1 is low pitched and dull, sounding like a lub. S2 is a higher pitched and shorter sound and creates the sound dub. Count the number of lub-dubs occurring in 1 minute. An inefficient contraction of the heart that fails to transmit a pulse wave to the peripheral pulse site creates a pulse deficit. To assess a pulse deficit, ask another nurse to assess the radial pulse rate while you assess the apical rate. Tachycardia is an abnormally elevated heart rate, more than 100 beats per minute in adults. Bradycardia is a slow rate, less than 60 beats per minute in adults.
