Q False in hemorrhagic shock? (# DNB SS )
A. Low heart rate
B. Cold extremity
C. Due to fluid losses
D. Vascular resistance high
Isotonic fluid
Q) Isotonic fluid solution is
Answer: C – Ringer lactate
Ringer lactate and Normal saline are isotonic fluids. They are useful in replacing GI losses. Ringer lactate has a bit of potassium as well.
Ringer Lactate (Correct Answer):
Ringer lactate is an isotonic solution, meaning its osmolarity (around 273 mOsm/L) is close to that of human blood (around 275–295 mOsm/L). This solution contains electrolytes like sodium, potassium, calcium, and chloride, helping maintain fluid and electrolyte balance. It's commonly used for fluid replacement in surgical and trauma patients.
A. Half Normal Saline (0.45% NaCl):
Half normal saline is a hypotonic solution (~154 mOsm/L), which draws water into cells and may cause swelling—unsuitable for isotonic fluid replacement.
B. 1/5th Normal Saline (0.18% NaCl):
This is also hypotonic (~77 mOsm/L), risking excessive fluid entering cells and causing edema—unsuitable as an isotonic option.
D. Dextrose in Normal Saline (D5NS):
D5NS is hypertonic due to added dextrose, increasing osmolarity above blood levels, which can lead to water exiting cells and potential dehydration.

Vascular ring
True Vascular Ring - NEET SS Surgery MCQ
Q) Which is a true vascular ring?
Correct Answer: b) Double aortic arch
Double aortic arch is a classic example of a true vascular ring. It forms a complete ring around the trachea and esophagus, leading to compressive symptoms such as stridor, wheezing, or feeding difficulties.
Pulmonary artery sling is not a vascular ring. It is a congenital anomaly where the left pulmonary artery arises from the right pulmonary artery and passes between the trachea and esophagus but does not form a complete ring.
Cervical aortic arch is a rare anomaly and does not form a true vascular ring.
Aberrant origin of subclavian artery (e.g., aberrant right subclavian artery from the descending aorta) is considered a partial ring and usually causes less significant symptoms compared to true vascular rings.
