Chapter 32 Questions
Question 1 of 5
The nurse is reviewing laboratory data for an older-adult patient. Which of the following results should be of most concern?
Correct Answer: A
Rationale: The total WBC count is not usually affected by aging, and the low WBC here would indicate that the patient's immune function may be compromised. The platelet count is normal. The slight decrease in hemoglobin and hematocrit is not unusual for an older patient.
Question 2 of 5
The nurse is caring for a patient who is receiving heparin. Which of the following laboratory tests should the nurse monitor?
Correct Answer: D
Rationale: aPTT testing is used to determine whether heparin is at a therapeutic level. FDP is useful in diagnosis of problems such as disseminated intravascular coagulation (DI
C). PT and INR are most commonly used to test for therapeutic levels of warfarin.
Question 3 of 5
The nurse is evaluating the red cell indices result of a patient's laboratory report. Which of the following interpretations is correct related to a low mean corpuscular volume (MCV)?
Correct Answer: D
Rationale: The MCV is low when the RBCs are smaller than normal. Inadequate numbers of RBCs are an indication of anemia. Low levels of hemoglobin in the RBCs and hypochromic RBCs result in a low mean corpuscular hemoglobin (MCH).
Question 4 of 5
The nurse is caring for a patient whose complete blood count (CBC) and differential indicate that the patient is neutropenic. Which of the following actions should the nurse include in the plan of care?
Correct Answer: C
Rationale: Neutropenic patients are at high risk for infection and sepsis and should be monitored frequently for signs of infection. The other actions would not address the patient's neutropenia.
