a nurse is caring for a patient who has hemophilia. the patient reports pain
and swelling in a joint following an injury. which of the following actions
should the nurse take? ~CORRECT ANSWER~✓✓prepare for replacement
of missing clotting factors
-hemophilia is a hereditary bleeding disorder in which blood clots slowly
and abnormal bleeding occurs
-caused by a deficiency in most common clotting factor, factor VIII
(hemophilia A)
-aggressive factor replacement is initiated to prevent hemarthrosis that can
result in long-term loss of range of motion in repeatedly affected joints
-coagulation tests that measure platelet function, such as bleeding time, are
used to Dx, not treat, hemophilia
-aspirin and other NSAID's, and some herbal supplements should be
avoided b/c they interfere w/ clotting function
-affected joint should be elevated to allow blood to drain away from pt
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?
~CORRECT ANSWER~✓✓omega 3 fatty acids

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? ~CORRECT 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? ~CORRECT
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 minutes after
the infusion begins. Which of the following actions should the nurse take
first? ~CORRECT ANSWER~✓✓stop infusion
-Priority: b/c pt has manifestations of allergic rxn
-nurse should maintain IV access by initiating infusion of 0.9% sodium
chloride solution using a new IV administration set
-nurse should send blood container and tubing to blood bank for a repeat
typing and culture
