A client who has a history of a major myocardial infarction is taking digoxin. The nurse explains this medication helps increase cardiac output by:
1. Increasing the heart rate
2. Reducing the resistance of pulmonary circulation
3. Increasing the force of the myocardial contraction
4. Increasing cardiac conduction
ANS: 3
Myocardial contractility affects stroke volume and cardiac output. Increased contraction increas-es the amount of blood ejected by the ventricles. Digoxin increases cardiac output by inhibiting the sodium-potassium ATPase, which makes more calcium available for contractile proteins, which results in a positive inotropic effect. One of the adverse reactions of digoxin is bradycar-dia. Digoxin does not reduce the resistance of pulmonary circulation or affect the electrical con-duction of the heart.

The nurse working in a plastic surgeon's office admits a client for a consult about possible liposuction. The client states, "I am so sick of dieting. It would be much easier to just have this fat surgically removed
" The nurse responds most accurately by saying: 1. "Liposuction should not be considered a replacement for dieting, because remaining fat cells can expand if excess calories are taken in." 2. "Now you will be able to eat what you want so long as you don't eat excessive numbers of calories." 3. "While liposuction will reduce the need for dieting, it will not fully eliminate it." 4. "You will need to diet even more carefully after liposuction, because you will be at greater risk for fat cell production."
What is meant by the term "evidence-based practice"?
a. Using nursing research findings to develop nursing theory b. Integrating the research process into nursing administration c. Studying research from the social sciences and applying it to practice d. Applying research findings; patient care data, preferences, and values; and nursing expertise to nursing practice
Which nursing actions could the nurse delegate to a licensed practical/vocational nurse (LPN/LVN) who is part of the team caring for a patient with Alzheimer's disease (select all that apply)?
a. Develop a plan to minimize difficult behavior. b. Administer the prescribed memantine (Namenda). c. Remove potential safety hazards from the patient's environment. d. Refer the patient and caregivers to appropriate community resources. e. Help the patient and caregivers choose memory enhancement methods. f. Evaluate the effectiveness of the prescribed enteral feedings on patient nutrition.
The patient is having at least 75% of nutritional needs met by enteral feeding, so the health care provider has ordered the parenteral nutrition (PN) to be discontinued. However, the nurse notices that the PN infusion has fallen behind
What should the nurse do? a. Increase the rate to get the volume caught up before discontinuing. b. Stop the infusion as ordered. c. Taper infusion gradually. d. Hang 5% dextrose.
