Explanation

The normal hemoglobin (Hb) level for adult females is 12–16 g/dL and for adult males is 14–18 g/dL.
The unit 'g%' is equivalent to grams per deciliter (g/dL), which is the standard unit for measuring hemoglobin concentration.
The range of 12 to 15 g% is the most appropriate choice as it encompasses the normal range for adult females and the lower limit for adult males.

Option B: The unit 'mg%' (milligrams per deciliter) is incorrect. Hemoglobin is measured in grams, not milligrams. A value in mg% would be 1000 times too low.
Option C: This range is too wide and includes an abnormally low value. A hemoglobin level of 10 g/dL is indicative of anemia and is not considered normal for an adult.
Option D: This option is incorrect for two reasons: the numerical range is too broad (10 g/dL is anemic), and the unit 'mg%' is incorrect.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Normal hemoglobin levels in adults as background academic context rather than a clinical decision trigger.
Nurses must be able to interpret hemoglobin results to identify conditions like anemia or polycythemia and understand their impact on a patient's oxygenation status.
A low hemoglobin level is a critical finding that requires nursing assessment for signs of hypoxia, such as fatigue, dizziness, and shortness of breath, and may necessitate interventions like oxygen therapy or preparation for a blood transfusion.
What if? If a patient's hemoglobin drops to 8 g/dL after surgery, the nurse's priority action would be to assess the patient for signs of active bleeding and hemodynamic instability (e.g., hypotension, tachycardia), notify the healthcare provider immediately, and prepare for potential interventions like a blood transfusion.

How to Approach the Question

First, identify the core of the question, which is asking for the 'normal hemoglobin level in an adult'.
Pay close attention to both the numerical values and the units provided in the options.
Eliminate options with incorrect units. Hemoglobin is measured in grams (g), not milligrams (mg). This immediately rules out options B and D.
Compare the remaining options (A and C) based on the numerical range. Recall the standard physiological ranges for hemoglobin.
Recognize that a hemoglobin level of 10 g% is generally considered anemic, making the range '10 to 18 g%' (Option C) incorrect as it includes a pathological value.
Select the option that represents a widely accepted normal range. The range '12 to 15 g%' (Option A) falls squarely within the normal physiological values for adults, particularly females.
