First Semester Module – Foundation Module Theme (HYPOVOLUMEA)

A 38-year-old male came to ER with severe diarrhea (10 episodes) during last 6 hours. His B.P was 90/60 mmHG, Pulse 110/min, R.R 24/min, temperature, (a febrile.)

Investigation shows *Na: 134 mol/L, *K+: 2.5 mol/L. Complete Blood Count (CBC): Normal

On the basis of above scenario answer the following question.

*He was diagnosed as a case of Hypovolumic shock by the In-charge of ER.

Normal Values

Na= 138-146 mol/L

K+=3.8-5 mol/L
