a. 5%dextrose

b. Normal Saline

c. ½ Normal Saline

d. ¼ Normal Saline

Answer (b) Normal Saline

Reference: Harrison 16^th Edition Page 257

Note : If the question stem is Hypernatremic dehydration can be treated with all except, then the answer will Normal Saline.

Ä Dehydration is often categorized according to serum sodium concentration as isonatremic (130-150 mEq/L), hyponatremic (<130>150 mEq/L). Isonatremic dehydration is the most common (80%). Hypernatremic and hyponatremic dehydration each comprise 5-10% of cases. Variations in serum sodium reflect the composition of the fluids lost and have different pathophysiologic effects.

o Isonatremic (isotonic) dehydration occurs when the lost fluid is similar in sodium concentration to the blood. Sodium and water losses are of the same relative magnitude in both the intravascular and extravascular fluid compartments.

o Hyponatremic (hypotonic) dehydration occurs when the lost fluid contains more sodium than the blood (loss of hypertonic fluid). Relatively more sodium than water is lost.

o Hypernatremic (hypertonic) dehydration occurs when the lost fluid contains less sodium than the blood (loss of hypotonic fluid).

37) Silent Chest is seen in

a. Acute Severe Asthma

b. H16- 1511

Answer (a) Acute Severe Asthma

Reference: Question Number 16 in Review Part 15 of Nelson 15^th Edition

In a tachypneic patient with asthma, poor air entry and exit (no wheeze) are very serious signs of acute life-threatening airway obstruction. It is a medical emergency. Many people believe the absence of wheezing means that the attack is abating. To the contrary, treatment should be started immediately. A silent chest or no stridor (either in the child making maximum effort to breath or in the exhausted child) are very sinister indications of complete airway obstruction. Indeed, the most ominous sign is the "silent chest" where obstruction is so severe that no gas flow is occurring.
