Question88:-A 67-year-old chronic male smoker, a known case of small cell carcinoma, was admitted to hospital with altered sensorium, nausea and dizziness. His vital signs were
stable. Liver function tests, urea, and creatinine were normal. Serum sodium was 118 mEq/L and serum potassium was 4.0 mEq/L. Allthe following regarding the treatment of
hyponatremia are true except

‘Ayo prevent further decrease in the serum sodium concentration

B:-To decrease intracranial pressure in patients at risk for developing brain herniation

பிர alleviate symptoms of hyponatremia

D-Sodium may be corrected at the rate of 3-4 mEq/L for an initial few hours or till symptoms subside

Correct Answer:- Option-D
Question89:-A 75-year-old male patient, a case of Chronic Obstructive Pulmonary Disease (COPD), was transferred from another hospital with complaints of fever, increased
breathlessness for 5 days, and altered sensorium since 1 day. He also had an episode of seizure 1 day. He was being managed on the lines of acute exacerbation of COPD with cor
pulmonale with pneumonia. He received antibiotics and diuretic therapy in the previous hospital. On evaluation, his laboratory values showed hemoglobin 13 gid, packed cell volume
‘of 38.5%, serum sodium 160 mEq/L, serum potassium 3.0 mEq/L, serum Urea 146 maid, and serum creatinine of 1 mg/dl. Which of the following is true about the current scenario ?

‘Achim to correct sodium levels at the earliest

B:-10-15% improvement in sodium levels in first 2 h

C=Correction in chronic (> 48 h) settings : Total less than 10-12 mEg/24 h

D:-Slow correction will cause rapid shift of water inside the brain causing cerebral edema and seizures

Correct Answer:- Option-C
Question90:-A 50-year-old male patient was admitted with generalized weakness and abdominal distension. On examination, he was found to be alert and hemodynamically stable.

showed all the following features except

Correct Answer:- Option-é
Question91:-A 60-year-old diabetic male patient, hypertensive and on Angiatensin-Converting Enzyme (ACE) inhibitors, was admitted with dizzy spells. On admission, his pulse was
60/min, BP was 110/70 mmHg, and sensorium was normal. His blood biachemistry showed urea 90 mg/dl, creatinine 2.0 mg/dl, Na 130 mEq/L and K 6.5 mEQIL. Which of the following
statements is untrue regarding calcium therapy in such a patient ?

‘AcGive calcium gluconate or calcium chloride-10 ml. of 10% solution over 2 min under continuous ECG monitoring

B:-Intravenous calcium works within minutes and the effect is long-lasting (3-6 hrs)

CxCaleium acts by directly antagonizing the membrane action of hyperkalemia and does not cause lowering of serum potassium

D-Calcium chloride contains three times more elemental calcium compared to calcium gluconate (13.6 vs. 4.6 mEq in 10 mL of 10% solution) and is the preferred drug

Correct Answer:- Option ®
