ch. 25 Structure and Function of the Cardiovascular System
If the parasympathetic neurotransmitter releases acetylcholine, the nurse should anticipate observing what changes in the ECG pattern?
Slowing of heart rate to below 60 beats/minute
A nurse is assessing a female client and notes that her left arm is swollen from the shoulder down to the fingers, with non-pitting edema. The right arm is normal. The client had a left-sided mastectomy 1 year ago. What does the nurse suspect is the problem?
Lymphedema
Blood flow in the circulatory system depends on a blood volume that is sufficient to fill the blood vessels and a pressure difference across the system that provides the force to move blood forward. What is the total blood volume in an adult?
70 to 75 mL/kg
Select the correct sequence of blood return to the heart.
Capillaries, venules, veins, right atrium
When reviewing diagnostic test results and physical assessment data for a client with a history of stage II hypertension, which of the following would be of most concern to the nurse?
An ejection fraction of 40%
The heart valves control the direction of blood flow. What is the function of the pulmonic valve?
Controls the direction of blood flow from the right side of the heart to the lungs
A client has prominent jugular veins. What type of medical problem is associated with prominent jugular veins?
Right-sided heart failure
The physician states that a client has adequate collateral circulation. The nurse interprets this as:
Long-term compensatory regulation of blood flow
A nurse is caring for a client with right heart failure caused by pulmonary hypertension. Which hemodynamic parameter is most appropriate for the nurse to monitor?
Pulmonary arterial pressure (PAP)
Downstream peripheral pulses have a higher pulse pressure because the pressure wave travels faster than the blood itself. What occurs in peripheral arterial disease?
The pulse decreases, rather than increases, in amplitude.
