◉ a nurse is completing a medication history for a patient who reports
using fish oil as a dietary supplement. which of the following substances
in fish oil should the nurse recognize as a health benefit to the patient?
Answer: omega 3 fatty acids
-helps lower risk of cardiovascular dz and stroke by decreasing
triglyceride levels
-antioxidants: substances naturally occurring in fruits and veggies, as
well as in nuts, grains, and some meat, poultry, and fish
-beta-carotene, vitamin A, C, E, and selenium are some of most
commonly known antioxidants
-can slow/prevent development of cancer
-beta-carotene: precursor to vitamin A, functions as fat-soluble
antioxidant which protects body from deleterious free-radical rxns
◉ A nurse is reviewing a patient's repeat lab results for hours after
administering fresh frozen plasma. Which of the following lab results for
the nurse review? Answer: prothrombin time (PT_
,-FFP is plasma rich in clotting factors and is administered to treat acute
clotting disorders
-desired effect: decrease in PT
-review WBC's if there's possible infection
-review platelet count following admin of platelets
-review HCT following admin of packed RBC's
◉ A nurse is assessing a patient who has right-sided heart failure. Which
of the following findings should the nurse expect? Answer: dependent
edema
-blood return from venous system to R atrium is impaired by weakened
R heart
-consecutive systemic venous backup leads to development of dependent
edema
-Left-sided HF: pts w/ this disorder have decreased cardiac output which
causes decreased capillary refill; blood returns from lungs via pulmonary
vein is slowed, causing fluid buildup in lungs that results in SOB;
dizziness can occur d/t decreased cardiac output
◉ A nurse is administering a unit of packed red blood cells to a patient
who is postoperative. The patient reports itching and has hives 30

-nurse should obtain urine sample from pt to determine if hemoglobin is
in urine
◉ A nurse is monitoring a patient who had a myocardial infarction. For
which of the following complications should the nurse monitor in the
first 24 hours? Answer: ventricular dysrhythmias
-after MI, electrical conduction system of heart can be irritable and
prone to dysrhythmias
-ischemic tissue caused by infarction can interfere w/ normal conduction
patterns of heart's electrical system
-infective carditis: occurs when bacteria invades endothelial surface of
heart; usually seen in pts who have prosthetic heart valves or
pacemakers
-pericarditis: can occur 10 days to 2 months following MI; is an
inflammation of pericardial sac that surrounds heart and usually results
from infection, connective tissue disorders, or trauma
◉ The nurse is transfusing a unit of O-negative fresh frozen plasma to a
patient with blood type is be positive. Which is the following findings
