A low reticulocyte count in a pt with anemia most likely indicates:
A. sick cell anemia. B. risk of thrombocytosis. C. possible bone marrow underproduction of RBCs D. hemophilia |
C. possible bone marrow underproduction of RBCs
Underproduction of RBCs is reflected by a low reticulocyte count. A person with sickle cell anemia may have an elevated reticulocyte count, especially in sickle cell crisis. Platelet overproduction and coagulopathy are not reflected by the reticulocyte count. |
|
|
When assessing the WBC differential, a "left shift" (increased number of bands) usually indicates:
A. acute leukemia B. hypersensitivity reaction C. immunosuppression D. an infectious process |
D. an infectious process
Increased numbers of band in the WBC differential can indicate an infectious process. In acute leukemia, the WBC differential may show the presence of blasts. An allergic reaction may be shown by increased numbers of eosinophils. |
|
|
A pt with chronic severe alcoholism should be assessed for a potential bleedins disorder related to:
A. vitamin K deficiency and insufficient production of coagulation factors. B. overproduction of platelets. C. congenital bleeding disorder. D. bone marrow dysfunction. |
A. vitamin K deficiency and insufficent production of coagulation factors.
Liver dysfunction from chronic alcoholism causes decreased production of coagulation factors. Overproduction of platelets is related to bone marrow dysfunction. A congenital bleeding disorder is an inherited coagulopathy that is not acquired through alcohol abuse. Bone marrow dysfunction is not caused by alcohol abuse. |
|
|
Which of the follow is NOT related to the role of nutrition in preventing infection?
A. Lymphocyte function and antibody production B. Hemostasis C. Wound healing D. Skin integrity maintenance |
B. Hemostasis
Hemostasis could be affected by a decreased intake of vitamin K, but this is not related to prevention of infection. Nutrition is an important factor in lymphocyte function, antibody production, wound healing, and skin integrity maintenance. |
|
|
A complete cell blood count (CBC) gives an overall indication of:
A. coagulation times. B. a patient's cardiac output. C. bone marrow production. D. immune status. |
C. bone marrow production.
The CBC provides an overall indication of bone marrow production of red blood cells, white blood cells, and platelets. |
|
|
The nurse may assess an elevated reticulocyte count when the patient:
A. is anemic. B. is fasting. C. has increased intracranial pressure. D. has a valve replacement |
A. is anemic
The reticulocyte count indicates the amount of immature RBCs and is increased in hemolytic anemia, hemorrhage, leukemia, malaria, polycythemia, pregnancy, sickle cell anemia, thalassemia, and thrombotic thrombocytopenic purpura. |
|
|
Your critically ill patient was just admitted for a severe allergic reaction. When assessing his leukocytes with differential, you are likely to find:
A. lymphocytosis. B. monocytosis. C. an elevated eosinophil count. D. All of the above are correct |
C. an elevated eosinophil count
Eosinophils are elevated in allergies, hypersensitivity reaction, parasitic infections, immunological disorders, and adrenal insufficiency. |
|
|
A critically ill patient has an elevated platelet count, putting her at risk for:
A. dehydration. B. thrombosis. C. liver impairment. D. disseminated intravascular coagulation |
B. thrombosis.
An elevated platelet count indicates either increased platelet production or decreased platelet destruction. These platelets may function abnormally, causing aberrant bleeding and clotting. |
|
|
Intradermal skin testing can be done to evaluate cell-mediated immunity. A common agent used is:
A. measles. B. malaria. C. chlamydia. D. Candida |
D. Candida.
Common agents used for intradermal testing are mumps, Candida, trichophytin, and tuberculin. |
|
|
Interventions implemented to protect the immunosuppressed patient would include which of the following measures?
A. Permit cooked foods only. B. Allow no fresh flowers or live plants in the room. C. Provide a private room with laminar flow or positive pressure. D. All of the above are correct. |
D. All of the above are correct.
Nursing interventions for the immunocompromised patient include providing a private room, using laminar flow or positive pressure room, strict handwashing, permitting cooked foods only, no fresh flowers or live plants, and avoiding stagnant water in the room. |
|
|
Which of the following medical regimens can compromise a patient's immune functioning?
A. Steroid therapy B. Antibiotics such as tetracycline C. Prolonged insulin use D. Both a and b are correct. |
D. Both a and b are correct.
Many medications affect immunocompetence. Antibiotics may impair bone marrow function and steroids display many immunological effects. |
|
|
When admitting a critically ill patient with anemia, then nurse will most probably assess the patient for:
A. tachycardia and tachypnea. B. joint pain and muscle spasms. C. chronic, persistent cough and hemoptysis. D. hemiparesis and vertigo |
A. tachycardia and tachypnea.
Signs of anemia include pallor, dyspnea, dizziness, tachycardia, and glossitis. |
|
|
A “shift to the left” in the WBC differential indicates probable infection.
a. True b. False |
A. True
A “shift to the left” in the WBC differential refers to an increase in the number of bands, which usually indicates an infectious process. |
|
|
A deficiency in factor VIIIR (von Willebrand's disease) will result in decreased bleeding times.
a. True b. False |
B. False
A deficiency in factor VIIIR (von Willebrand's disease) will result in decreased ability of the platelets to adhere to the injured vessel wall. |
|
|
Low platelet counts are found in disseminated intravascular coagulation (DIC).
a. True b. False |
A. True
DIC and TTP are serious disorders that involve low platelet counts. |
|
|
The physician is going to assess the bone marrow function of a critically ill patient. The nurse will prepare the patient for:
A. a computerized tomography (CT). B. intradermal skin testing. C. bone marrow aspiration for biopsy. D. magnetic resonance imaging (MRI). |
C. bone marrow aspiration for biopsy.
Bone marrow aspiration and biopsy is the most important diagnostic test for determining bone marrow function. |
