Question 12

A pulse deficit is the difference between:

Answer 12

Use the Doppler ultrasound device.

Question 15

Which outcome best reflects achievement of the goal, “The client will demonstrate correct steps in taking his own pulse rate”?

Answer 15

palpation of the radial pulse on the thumb side of the inner aspect of the wrist.

Question 16

A nurse is assessing the blood pressure of a client using the Korotkoff sound technique. The nurse notes that the phase I sound disappears for 2 seconds. What should the nurse document on the progress record?

Answer 16

There is an auscultatory gap.

Question 17

The nurse understands that accurate blood pressure taking is dependent on several factors. Which example will most likely render an accurate blood pressure reading?

Answer 17

A nurse can most accurately assess a client’s heart rate and rhythm by which of the following methods?

Answer 21

listen with the stethoscope at the fifth intercostal space left mid-clavicular line

Question 22

A 62-year-old female client being treated for hypertension did not take her daily BP medication over the weekend because she was out of medication and the pharmacy was closed.

What is the most appropriate thing for this nurse to advise this client?

Answer 22

To take the recommended daily dose of medication and call the health care provider if the average of her HBPM readings increase/decrease by 10, or if she has any other concerns.

After taking vital signs of an older adult, the nurse writes down findings as T = 98.9/37.2 oral, P = 104, R = 18, BP = 120/82. Based on the collected data, which step would the nurse take next?

Answer 23

Take pulse again to assess for tachycardia

Question 24

A nurse is assessing an apical pulse on a cardiac client. The client is taking digoxin, which is a cardiac medication. The nurse can anticipate that the digoxin will:

Answer 24

decrease the apical pulse.

Question 25

Answer 25

The client’s most recent temperature

Question 26

The nurse is preparing to administer a medication that the client takes to treat a cardiac arrythmia. Which site should the nurse use to assess pulse in this client?

Answer 26

Answer 27

“A heart rate of 160 beats/min is normal for a healthy infant.”

Question 28
