5.

An obese 43 year old man presents to the emergency department with history of fever for 4 days. He's lethargic and tachypniec and is triaged to the Red Zone. High flow mask oxygen is administerd immediately and an IV cannula is inserted. His BP is 110/70mmHg,  HR 110/min, RR 26/min and SpO2 is 100% on HFM. Blood is drawn for testing and IV 0.9% saline 10ml/kg/hr is administered as patient has cool peripheries with a moderate volume pulse. A bedside ECHO done for the patient shows moderate cardiac contractility. A bedside dengue combo test shows a positive NS1. What would you do next:

a)

Reduce rate of fluid administration immediately

b)

Assess fluid status from ECHO

c)

Assess fluid status with IVC scan

d)

Change IV fluids to colloid

6.

The following are possible differential diagnosis for a presentation of thrombocytopenia with fever EXCEPT:

a)

Malaria

b)

Dengue fever

c)

Sepsis

d)

Influenza

7.

A young man admitted to ICU with complaints of fever for one week, rashes, abdominal pain and blackish stool. BP was 100/70. Which laboratory investigations should be tested:

a)

NS1 antigen

b)

Dengue PCR

c)

Dengue IgM ELISA

d)

Viral culture

8.

These are the disease MONITORING tests for SEVERE DENGUE, EXCEPT :

a)

White blood count

b)

Platelet count

c)

Dengue IgM

d)

Ferritin level

9.

Positive result indicates acute dengue infection, EXCEPT:

a)

Dengue PCR

b)

Dengue IgG antibody

c)

Dengue NS1 antigen

d)

Dengue Viral culture

10.

A 7-year-old child with confirmed dengue has been febrile for 3 days. He is active, drinking well, has no vomiting or bleeding. What is the best management plan?

a)

Immediate hospital admission

b)

Home care with fluid monitoring and follow-up

c)

Syrup ibuprofen 10mg/kg 12hourly

d)

Start IV fluids

11.

You are monitoring a child on IV fluids during the critical phase. Which of the following is the BEST indicator that the child is improving?

a)

Rising hematocrit

b)

Increasing platelet count

c)

Persistent vomiting

d)

Urine output ≥1 ml/kg/hour

12.

A 9-year-old child with dengue develops hypotension, cold extremities, and narrow pulse pressure. What is the MOST APPROPRIATE immediate fluid resuscitation dose?

a)

10 mL/kg of NS over 1 hour

b)

10 mL/kg of colloid over 1 hour

c)

20 mL/kg of NS over 15–30 minutes

d)

20 mL/kg of 1/2NSD5% over 15-30 minutes

13.

A 29-year-old woman with severe dengue presents with persistent fever, bicytopenia, and liver failure ( ASt>3000, INR 1.5) on day 9 of illness. She is not in shock, but her condition worsens despite adequate fluid resuscitation. Investigations show ferritin 15,000 µg/L, fibrinogen 1.2 g/L, and triglycerides 3.6 mmol/L.

Which of the following best distinguishes true HLH from hyperinflammatory response due to under-resuscitation?

a)

Progressive worsening of shock and lactate levels

b)

Rising ferritin & worsening cytopenias beyond critical phase 

c)

Rapid improvement after additional fluid boluses

d)

Presence of isolated transaminitis without cytopenias

14.

A 41-year-old obese woman (108 kg) with dengue infection presents 5 hours into the critical phase with lethargy, pulse 116/min, BP 110/90 mmHg, and cool peripheries. She has received 4.5 pints of normal saline . urine output is 0.4-0.5cc/kg/hr. Hematocrit decreased from 51%→ 47%, platelets 10 × 10⁹/L, and lactate reduced from 3.4 to 3.2 mmol/L.

Her baseline HCT is 38%.She is currently on 5cc/kg/hr of Normal saline

 

What is the most appropriate next step?

a)

Give 1–2 pints of packed red cells immediately to improve oxygen delivery

b)

Continue normal saline but treat for compensated shock ie increase the infusion rate to 10cc/kg.hr

c)

Switch to a colloid such as Dextran or HES and run cautiously at5cc/kg/hr

d)

Initiate 5% albumin infusion at 7 cc/kg/h

15.

A 30 year old man, baseline HCT of 42%, presents with severe dengue. After 5 hours of resuscitation, the patient’s hematocrit decreases from 51% → 40% following multiple fluid boluses. The patient s parameters improve with a steadier BP of 120/70. However HR 100  with persistent cold extremities .

Urine output is 0.8cc/kg/hr and lactate from 4 reduced to 2.3. His ALT is 500 and AST is 880.

The medical officer plans a blood transfusion because “the hematocrit is dropping.”

What is the best interpretation and next management step?

a)

Proceed with transfusion because falling Hct indicates hemorrhage

b)

Do not transfuse; the Hct fall is dilutional, and multiple parameters have improved

c)

Increase normal saline rate to maintain Hct >50%

d)

Start inotropes immediately

16.

RM 1000
