Chapter21 Hemato Flashcards
Which assessment finding is considered a normal change in an older patients hematological system?
- Mild anemia
- Decrease in lymphocyte function
- Decrease in platelet adhesiveness
- Increased number of stem cells in the bone marrow
Correct Answer: 2
Rationale 1: Mild anemia is not a normal part of the aging process, and should be investigated and treated.
Reference: Page 590
Rationale 2: Changes in the hematologic system that occur with aging include a decrease in the functioning of lymphocytes, including cellular immunity.
Reference: Page 590
Rationale 3: Changes with aging include an increase in platelet adhesiveness.
Reference: Page 590
Rationale 4: Changes with aging include a slight decrease in the number of stem cells in the bone marrow.
Reference: Page 590
While completing an assessment the nurse is concerned that an older patient is experiencing anemia. What did the nurse assess in this patient?
Standard Text: Select all that apply.
- Pallor
- Joint pain
- Respiratory rate 14
- Pulse 68 and regular
- Dyspnea on exertion
Correct Answer: 1,2,5
Rationale 1: Manifestations of anemia in an older patient include pallor.
Reference: Page 590
Rationale 2: Manifestations of anemia in an older patient can include joint pain.
Reference: Page 590
Rationale 3: A respiratory rate of 14 is not a manifestation of anemia in an older patient.
Reference: Page 590
Rationale 4: A pulse rate of 68 is not a manifestation of anemia in an older patient. The heart rate would be increased if anemia were present.
Reference: Page 590
Rationale 5: Dyspnea on exertion is a manifestation of anemia in an older patient.
Reference: Page 590
An older patient with chronic renal failure is exhibiting manifestations of anemia. Why is this occurring in the patient?
- The result of renal dialysis
- Loss of the kidney hormone erythropoietin
- Loss of appetite related to elevated blood urea nitrogen (BUN) and creatinine levels
- Loss of blood through the urine because the failing kidney does not function properly
Correct Answer: 2
Rationale 1: Hemodialysis does not cause anemia.
Reference: Page 594
Rationale 2: Anemia associated with renal failure is related to the loss of erythropoietin, which is produced by the healthy kidney and stimulates bone marrow to produce red blood cells.
Reference: Page 594
Rationale 3: Anemia is not caused by a loss of appetite or elevated blood urea nitrogen and creatinine levels.
Reference: Page 594
Rationale 4: Renal failure causes the loss of protein, not blood, through the urine.
Reference: Page 594
An older patient is diagnosed with hemolytic anemia. What will the nurse teach the patient about this disorder?
- It is caused by blood loss.
- It will be treated with folic acid.
- It causes the red blood cells to be misshaped.
- It is associated with a drop in the number of immature red blood cells produced.
Correct Answer: 2
Rationale 1: Hemolytic anemia is more common with aging and is caused by premature destruction of red blood cells and not from blood loss.
Reference: Page 595
Rationale 2: All hemolytic anemias require treatment with folic acid because this vitamin is consumed by the increased bone marrow production of red blood cells in response to the anemia.
Reference: Page 595
Rationale 3: The red blood cell is of normal size and shape in hemolytic anemia.
Reference: Page 595
Rationale 4: Hemolytic anemia causes an increase in immature red blood cells because they are released early from the bone marrow to compensate for the premature destruction.
Reference: Page 595
Which age-related change increases an older patients risk for pernicious anemia?
- Laxative dependency
- Increased incidence of cholelithiasis
- Decreased hydrochloric acid in the stomach
- Decreased peristalsis in the gastrointestinal tract
Correct Answer: 3
Rationale 1: Laxative use does not increase the older patients risk for developing pernicious anemia.
Reference: Page 596
Rationale 2: Cholelithiasis does not increase the older patients risk for developing pernicious anemia.
Reference: Page 596
Rationale 3: Pernicious anemia results when an older person lacks the needed intrinsic factor to absorb vitamin B12. A more common cause of low serum vitamin B12 results from the inability to split vitamin B12 from proteins in food. This inability may be the result of a deficiency of hydrochloric acid.
Reference: Page 596
Rationale 4: Decreased peristalsis in the gastrointestinal tract does not increase the older patients risk for developing pernicious anemia.
Reference: Page 596
What will the nurse most likely assess in an older patient with a vitamin B12 deficiency?
Standard Text: Select all that apply.

An older patient is prescribed a blood transfusion of two units packed red blood cells. What should the nurse do when providing the blood to this patient?
Standard Text: Select all that apply.
- Premedicate with an antihistamine.
- Administer each unit over 2 to 4 hours.
- Provide a diuretic between the two units as prescribed.
- Carefully assess the intravenous access site for infiltration.
- Monitor vital signs and urine output during the transfusion.
Correct Answer: 2,3,4,5
Rationale 1: An antihistamine is not routine provided to an older patient prior to administering a blood transfusion.
Reference: Page 597
Rationale 2: Transfusions for older people should be given slowly over a 2 to 4 hours period.
Reference: Page 597
Rationale 3: If several units of packed cells are to be infused often a diuretic is provided between units to prevent fluid overload and congestive heart failure.
Reference: Page 597
Rationale 4: Older people have more fragile veins. The intravenous site should be frequently assessed for signs of infiltration.
Reference: Page 597
Rationale 5: Because of the risk of heart failure from fluid overload the nurse should monitor the older patients vital signs and urinary output during the transfusion process.
Reference: Page 597
The nurse is reviewing assessment data collected during a routine physical examination. Which finding should be investigated as a pathological process of the hematologic system?
- WBC: 9000

A patient is prescribed warfarin (Coumadin) for chronic atrial fibrillation. Which laboratory value will be used to monitor the effects of this medication?
- Platelet count
- Hematocrit and hemoglobin
- Partial thromboplastin time (PTT)
- PT reported as international normalized ratio (INR)
Correct Answer: 4
Rationale 1: The platelet count is not affected by warfarin and is not used to monitor the effects.
Reference: Page 602
Rationale 2: Warfarin does not affect the hematocrit and hemoglobin levels.
Reference: Page 602
Rationale 3: The partial thromboplastic time (PTT) is used to monitor the effects of heparin.
Reference: Page 602
Rationale 4: The PT, a measure of the time required for a firm fibrin clot to form after reagents have been added to the blood sample, is the standard measure of efficacy. It is commonly reported in an international normalized ratio (INR) because the World Health Organization urged the adoption of a standardized reagent so that all laboratories would report standardized results. Warfarin will prolong the INR.

The nurse has completed a physical assessment with an older patient. Which assessment finding suggests the presence of deep-venous thrombosis?
- Two plus palpable pedal pulses
- Shortness of breath after activity
- Swelling in one leg with pitting edema
- Bilateral calf tenderness after walking up a flight of stairs
Correct Answer: 3
Rationale 1: Two plus palpable pedal pulses is a normal assessment finding.
Reference: Page 601
Rationale 2: Shortness of breath that subsides after activity is considered a normal assessment finding.
Reference: Page 601
Rationale 3: The hallmark of DVT is the rapid onset of unilateral leg swelling with pitting edema.
Reference: Page 601
Rationale 4: Bilateral calf tenderness may be a normal reaction to exercise of climbing stairs.
Reference: Page 601
An older patient receiving warfarin (Coumadin) alternate doses of 2.5 mg/5 mg has an INR of 6.3. What care should the nurse anticipate that this patient will need?
Standard Text: Select all that apply.
- Prepare to begin a heparin infusion.
- Administer vitamin K as prescribed.
- Administer protamine sulfate as prescribed.
- Withhold several doses of prescribed warfarin.
- Administer an additional dose of warfarin as prescribed.
Correct Answer: 2,4
Rationale 1: The INR is used to measure the effects of warfarin. Heparin is not administered for an elevated INR.
Reference: Page 602
Rationale 2: Vitamin K is the antagonist for warfarin and will most likely be prescribed for the patient. For INRs between 5 and 9 the recommendation may be to administer vitamin K 1.0 to 2.5 mg by mouth.
Reference: Page 602
Rationale 3: Protamine sulfate is the antagonist for heparin and is not indicated for an elevated INR level caused by warfarin.
Reference: Page 602
Rationale 4: For INRs between 5 and 9, the recommendation may be to omit the next several doses of warfarin.
Reference: Page 602
Rationale 5: Administering an additional dose of warfarin will cause the INR to be further elevated.
Reference: Page 602

The nurse is caring for a 65-year-old female patient with chronic renal failure. In reviewing the patients laboratory values, which result would the nurse expect to find?
- Hemoglobin 9 g/dL
- Hemoglobin 12 g/dL
- Hemoglobin 15 g/dL
- Hemoglobin 23 g/dL
Correct Answer: 1
Rationale 1: Chronic renal failure results in a two-fold increase in the chance of being diagnosed with anemia. A result of 9 g/dl is considered anemic for a female patient.
Rationale 2: Older women are considered anemic with a hemoglobin concentration below 12 g/dL.
Rationale 3: A hemoglobin level of 15 g/dL is considered normal.
Rationale 4: A hemoglobin level of 23 g/dL is considered elevated and would not be seen in the patient with chronic renal failure.
The nurse provides discharge teaching to an older patient diagnosed with iron deficiency anemia. Which statement by the patient indicates additional instruction is needed?
- I will take my ferrous sulfate tablet with my breakfast.
- I will take my ferrous sulfate tablet on an empty stomach.
- I will eat oatmeal for breakfast while I am taking my ferrous sulfate.
- I will increase my fluid intake while I am taking my ferrous sulfate.
Correct Answer: 2
Rationale 1: To minimize gastrointestinal distress, ferrous sulfate should be taken with meals.
Reference: Page 593
Rationale 2: Ferrous sulfate should be taken with meals. This patient statement indicates that additional teaching is needed.
Reference: Page 593
Rationale 3: Ferrous sulfate increases the risk of constipation. Ingesting oatmeal could reduce the risk of developing constipation from this medication.
Reference: Page 593

An older patient with a history of peptic ulcer disease is diagnosed with a vitamin B12 deficiency. How are these two disorders related?
- Peptic ulcer disease affects absorption of nutrients.
- Peptic ulcer disease reduces the surface area of the stomach.
- Medications used to treat peptic ulcer disease affect stomach acid.
- Medications used to treat peptic ulcer disease block the absorption of vitamins.
Correct Answer: 3
Rationale 1: The use of gastric acid-blocking agents may contribute to the development of vitamin B12 deficiency because they block the acid environment needed to break down and release vitamin B12 in ingested food. Peptic ulcer disease does not affect the absorption of nutrients as a cause for the deficiency.
Reference: Page 596
Rationale 2: The use of gastric acid-blocking agents may contribute to the development of vitamin B12 deficiency because they block the acid environment needed to break down and release vitamin B12 in ingested food. Peptic ulcer disease does not reduce the surface area of the stomach as a cause for the deficiency.
Reference: Page 596
Rationale 3: The use of gastric acid-blocking agents may contribute to the development of vitamin B12 deficiency because they block the acid environment needed to break down and release vitamin B12 in ingested food.
Reference: Page 596
Rationale 4: The use of gastric acid-blocking agents may contribute to the development of vitamin B12 deficiency because they block the acid environment needed to break down and release vitamin B12 in ingested food. Gastric acid-blocking agents do not block the absorption of vitamins.
