Correct Answer is B
Explanation
Choice A reason: A PR interval of 0.04-0.20 seconds is too broad and includes values that are both below and above the normal range.
Choice B reason: A PR interval of 0.12-0.20 seconds is the established normal range for adults, reflecting proper conduction through the AV node.
Choice C reason: The PR interval being less than half the R-to-R ratio is not a standard measurement for PR intervals and does not provide a specific range.
Choice D reason: A PR interval of 0.08-0.10 seconds is below the normal range and may suggest pre-excitation or an AV nodal (junctional) rhythm.
Correct Answer is C
Explanation
Choice A reason: An RBC count of 4,500,000/mL is within the normal range and would not typically cause symptoms of anemia.
Choice B reason: Normal RBC indices do not indicate anemia and would not explain the symptoms.
Choice C reason: A hemoglobin level of 8.2 g/dL is below the normal range and would be consistent with symptoms of anemia such as fatigue and palpitations.
