While living and hiking in the Rocky Mountains, a gentleman slipped and fell. He goes to an urgent care where an x-ray was done, and some blood was drawn for a CBC. The clinic informs him that he is anemic.
 
  What may contribute to this person's anemia? Select all that apply.
  A)
  Living in a high altitude
  B)
  Tissue hypoxia
  C)
  Inability to manufacture erythropoietin
  D)
  Destruction of RBCs caused by natural killer cells
  E)
  Dehydration

Question 2

A patient, who is experiencing some angina associated with atrial tachycardia, has been placed on verapamil (Calan), a calcium channel blocker.
 
  Knowing that this medication blocks the slow calcium channels, thereby depressing phase 4 and lengthening phases 1 and 2 action potential, the nurse should assess this patient for which of the following adverse reactions?
  A)
  Bradycardia
  B)
  Ventricular tachycardia
  C)
  Sudden cardiac death
  D)
  Increased cardiac output

Answer to Question 1

Ans:
A, B, C

Feedback:

The synthesis of erythropoietin is stimulated by tissue hypoxia, which may be brought about by anemia, residing at high altitudes, or impaired oxygenation of tissues due to cardiac or pulmonary disease. Dehydration will cause an elevated level of RBCs.

Answer to Question 2

Ans:
A

Feedback:

Calcium channel blockers (CCB) are used to slow the SA node pacemaker and inhibit conduction in the AV node, slowing the ventricular response in atrial tachycardias. Therefore, the nurse should be aware that it may cause bradycardia. CCB are not known to cause VT or sudden death. These medications reduce the force of myocardial contractility, thereby decreasing myocardial O2 demand. They do not increase cardiac output.
