Nursing Research:

QD1.  Discuss the characteristics and requirements that research tools should have on quantitative research to give validity to the study. Give some examples.

QD2.  Describe why you were to chose a specific method to select a sample over other methods. Defend the method you preferred.


QD1. Digitalis (e.g., digoxin, Lanoxin) is often prescribed for patients with atrial fibrillation. A common precaution prior to digitalis administration is to take an apical pulse.

a. Based on your understanding of the mechanisms of atrial fibrillation, why is taking a pulse by palpating the radial or other peripheral artery insufficient?

If there is a difference between the apical pulse and the radial pulse, discuss why the decision to administer or hold digitalis is based on the apical pulse rather than the radial or other peripheral pulse. In other words, why is the apical pulse considered “more accurate” in this situation?


QD2. A 10-year-old patient has developed cardiomyopathy and biventricular heart failure due to radiation and chemotherapy treatments received for pulmonary neuroblastoma. He has tachycardia, has tachypnea, and becomes winded and exhausted with minimal exertion.

  1. How, if at all, would you expect the manifestations of this patient’s biventricular failure to differ from those in a patient with biventricular failure from a massive left anterior wall myocardial infarction (MI)?
  2. How, if at all, would treatments for this patient’s biventricular failure differ from those for a patient with biventricular failure from a massive left anterior wall MI?
