Explain the relationship between BP and pedal edema
If Na is not properly excreted by the kidneys, it accumulates in the body. The hypertensive person has an increased concentration of Na in the blood vessel walls. This would lead to an edematous state within the walls and cause an increase in the resistance to blood flow. There is also an increase in Na in the interstitial spaces. This increase in particles will, by osmosis, draw water into the space. The increase in fluid takes up space, adds weight, and puts pressure on the outside walls of the blood vessels. This causes the heart to pump harder to continue adequate circulation. This edema is usually first evident to the naked eye in the patient's feet, called pedal edema.

A nurse manager has planned orientation activities for a new registered nurse. The new nurse is required to observe shift report and UAP delegation for a week
Then the new nurse is required to take shift report and delegate UAP assignments for a week. What is the rationale for making this orientation assignment? 1. Delegation is not taught at all nursing schools. 2. Shift report differs in all hospitals. 3. Shift report and UAP delegation are minimal tasks and good for novice nurses. 4. The manager should focus on those skills specific to the new nurse's role.
In mitral stenosis, the murmur occurs:
A. From S1 through S2 as a holosystolic murmur B. After an opening snap that is heard after S2 during diastole C. As a soft mid-systolic click D. A loud crescendo-decrescendo systolic murmur
The Office of Homeland Security has a mission to rebuild the crumbling public health infra-structures of each state and provide:
a. Vaccines for smallpox, anthrax, and plague b. Regulation of nuclear weapons c. Surveillance of bioterrorism threats d. Regulation of foreign nurses entering the United States
The nurse is discussing the proper technique for obtaining an accurate blood pressure reading with assistive nursing personnel
Which of the following statements reflect techniques that will minimize the risk of a false high systolic reading? (Select all that apply.) 1. "Slowly deflate the pressure from the cuff." 2. "Wrap the cuff snuggly around the client's arm." 3. "Always support the client's arm at the level of the heart." 4. "Be sure that the cuff is wide enough for the client's arm." 5. "Allow the arm to rest before repeating the blood pressure." 6. "Make sure your stethoscope is fitted in your ears appropriately."
