dyscrasias

A patient asks a nurse why they can only have 3 doses of nitroglycerin. What should the nurse tell the
patient?
The main side effect of this med is that it decreases BP. With each dose the BP is decreasing. So with
multiple doses, you will eventually have no BP.
,NSG-318: Introduction to Pharmacology
A patient was prescribed a topical/transdermal nitroglycerin. What should the nurse teach the patient
about this route?
The patient needs to be nitrate free for 8-12 hours to avoid developing a tolerance. Typically, this nitrate
free period can occur at night.
A patient asks the nurse what side effects they should look out for while on nitroglycerin. What
information should the nurse give to the patient?
Blurred vision, palpitation to compensate for the low BP, tolerance, and orthostatic hypotension. A life-
threatening side effect is circulatory collapse which is when there is no BP if you overdose
What intervention should the nurse take when administering nitroglycerin?
Monitor VS, position pt sitting or laying down when administering, advise pt to NOT drink alcohol while
taking med bc alcohol also decreases BP and instruct pt on how to properly store the med (not
childproof, and temp sensitive)
A student nurse asks what are the used on Tenormin. What should the nurse teach the student?
It is used to treat HTN, angina and treat acute MI
A doctor orders atenolol for a patient with a history of acute bronchospasms. What action should the
nurse take next?
a. Measure pts BP before administering
b. Give the next dose
c. Obtain a medical reconciliation
d. Question the HCPs order
d. Question the HCPs order. Bronchospasm is a contraindication because atenolol has a slight chance of
stimulating Beta 2
A new grad doctor asks the nurse what are the drug interactions for atenolol. What should the nurse
inform the doctor?
- Atropine and other anticholinergics bc it increases absorption
- NSAIDS decreases the effects
- Insulin and sulfonylureas increase the risk of hypoglycemia
A patient beginning Tenormin would like to know what side effects to look out for. What should the
nurse teach the patient?
Normal side effects are depression, cool extremities and ED. If you have any of the following side effects
you should report it: Dyspnea, bradycardia, excessive dizziness, early morning insomnia and mental
depression.

What is the therapeutic serum level of digoxin?
0.5 - 1 ng/ml
The nurse is caring for a patient on digoxin therapy. The student nurse asks the nurse what are signs

a. Depression
b. Circulatory Collapse
c. Tachycardia
d. Green or yellow hallos
D. Green or yellow halos, cardiac dysrhythmias, bradycardia, vomiting, anorexia and diarrhea
A patient on digoxin therapy reports having blurred vision and yellow halos and respirations are 5 per
minute. What action should the nurse take next?
a. Administer protamine
b. Administer digoxin immune fab
c. Administer vitamin K
d. Nothing these are normal side effects
B. Administer Digoxin Immune Fab. This med reverses the side effect of bradycardia
Which CAMs increase the risk of digitalis toxicity? SATA
a. Gingko
b. Ginseng
c. Cinnamon
d. Licorice
e. Aloe
f. Parsley
g. Green tea
h. Ephedra
Ginseng, Licorice, Aloe and Ephedra
A patient on digoxin therapy frequently takes CAMs. Which CAMs should the nurse educate the
patient to avoid?
Ginseng, St. John's Wort, Psyllium, Hawthorn, Licorice, Aloe, and Ephedra
What are 3 important things a nurse needs to watch for during digoxin therapy?
Apical pulse >60
Toxicity: 0.5-1.0 ng/mL
Potassium: Increases risk of digitalis toxicity
