A patient with suspected infection has WBC 15,000/µL, heart rate 118/min, new confusion, and blood pressure 86/52 mm Hg. What is the best action?

A
Treat the elevated WBC alone as proof of sepsis.
B
Assess the patient and activate the facility’s urgent escalation or sepsis pathway.
C
Wait until tomorrow to repeat the CBC.
D
Focus only on the WBC because vital signs are unrelated to blood counts.

Treat an INR of 5.2 as therapeutic for every patient taking warfarin.
B
Promptly assess bleeding and vital signs, then notify the responsible clinician or team for urgent direction.
C

A blood test result falls near the edge of a commonly cited adult reference range. What is the best approach to interpreting it?

A
Use a common adult range as definitive, regardless of the laboratory or patient.
B
Use the range printed on the patient’s report and compare with the patient’s baseline and clinical condition.
C
Treat any result outside a common range as proof of a specific disease.
D
Ignore the patient’s symptoms if the result falls within a common range.

For most hemodynamically stable hospitalized adults, around what hemoglobin value (g/dL) do guidelines support considering transfusion? Enter the approximate threshold; clinical context and exceptions still apply.

A patient reports fatigue and shortness of breath on exertion. Hemoglobin is 8.4 g/dL and hematocrit is 27%. Which interpretation and response are most appropriate?

A
Recognize anemia, assess symptoms and clinical context, and investigate the cause rather than deciding on transfusion from hemoglobin alone.
B
Conclude that the patient needs transfusion because the hemoglobin is below the common adult range.
C
Diagnose iron deficiency from these results alone and begin treatment without further assessment.
D
Dismiss the findings because shortness of breath can occur with a low MCV.

A patient receiving chemotherapy has an ANC of 300/µL and develops a temperature of 38.3°C. What is the priority response?

A
Wait for a repeat CBC to confirm the low white blood cell count.
B
Assess promptly and notify the responsible clinician or team immediately, following the febrile-neutropenia protocol.
C
Give an antipyretic and reassess at the end of the shift.
D
Reassure the patient that severe neutropenia prevents fever.

A patient with suspected infection has a WBC of 15,000/µL, heart rate of 118/min, new confusion, and blood pressure of 86/52 mm Hg. What is the best action?

A
Use the elevated WBC alone to confirm sepsis.
B
Recognize possible deterioration, assess the patient, and activate the facility’s urgent escalation or sepsis pathway.
C
Repeat the CBC tomorrow before notifying the care team.
D
Focus on the WBC because blood pressure and mental status are unrelated to blood counts.
