Answer to Question 1

C, D
Pulse rate assessment often reveals variations in heart rate. Two common abnormalities in heart rate are tachycardia and bradycardia. 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. A regular interval interrupted by an early beat, late beat, or a missed beat indicates an abnormal rhythm (not rate) or dysrhythmia. The apical pulse is located on the anterior chest wall at approximately the fourth to fifth intercostal space just medial to the left midclavicular line. An inefficient contraction of the heart that fails to transmit a pulse wave to the peripheral pulse site creates a pulse deficit.

Answer to Question 2

C
In semi-Fowler's position the head of the bed is at a 30-degree angle. Use this position for patients who cannot tolerate a supine position, such as those with cardiac and respiratory problems. Prone position is incorrect because it can compromise lung expansion. Lateral position is incorrect because patients who are obese or older do not tolerate this position for any length of time. Sims' position is incorrect because it is a semi-prone position that can compromise lung expansion.
