Q. Normal serum creatinine level(a) 0.5-1.1 mg/dl / |
🧪 Serum Creatinine – Nursing Rationale
What is Serum Creatinine?
Serum creatinine is a waste product that is formed from the metabolism of our muscles.
It is found in the blood, and the kidneys filter it out and excrete it through urine.
Therefore, the serum creatinine level is very important for assessing kidney function.
What does a Normal Serum Creatinine Level mean?
A normal serum creatinine level means that the kidneys are functioning properly
and are efficiently removing waste products from the body.
In adults, this level is generally between 0.5 – 1.1 mg/dl
(it may vary slightly depending on age, gender, and muscle mass).
✔ Why is Option (A) – 0.5–1.1 mg/dl correct?
Option A is correct because this range is the clinically accepted normal range
found in healthy adults.
✘ Option (B) – 0.6–2 mg/dl Why is it incorrect?
The upper limit in this option is 2 mg/dl,
which is higher than normal and may suggest kidney impairment.
Therefore, this is not considered a normal range.
✘ Option (C) – 0.1–0.6 mg/dl Why is it incorrect?
This range is too low. Such a low creatinine level is not typically found in the normal adult population,
and it is below the standard reference range.
✘ Option (D) – 0.8–2 mg/dl Why is it incorrect?
In this option as well, the upper limit is 2 mg/dl,
which does not represent normal kidney function.
Therefore, this option is also incorrect.
🩺 Exam Tip (For Nurses):
Serum creatinine is always an important part of the kidney function test (KFT).
Remembering the normal range is essential for both exams and clinical practice.
