Which of these is not a sign of the recovery phase?
General well-being improves
Classical rash of “isles of Red in the sea of whites” with generalised pruritus
Hematocrit level stabilises
recovery of WCC followed by recovery of platelet count
All of these are signs of compensated shock EXCEPT?
Normal or elevated systolic pressure
Narrow pulse pressure – weak pulse Tachycardia
Cool/cold and pale extremities
Reduce conscious level
All of these are signs of decompensated shock EXCEPT?
Increasing tachycardia
Feeble or absent peripheral pulse
Oliguria or anuria
Respiratory acidosis
The following is NOT a part of dengue charting
Blood pressure
DXT trend
Input and output fluid
Heart Rate
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:
Reduce rate of fluid administration immediately
Assess fluid status from ECHO
Assess fluid status with IVC scan
Change IV fluids to colloid
The following are possible differential diagnosis for a presentation of thrombocytopenia with fever EXCEPT:
Malaria
Dengue fever
Sepsis
Influenza
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:
NS1 antigen
Dengue PCR
Dengue IgM ELISA
Viral culture
These are the disease MONITORING tests for SEVERE DENGUE, EXCEPT :
White blood count
Platelet count
Dengue IgM
Ferritin level
Positive result indicates acute dengue infection, EXCEPT:
Dengue PCR
Dengue IgG antibody
Dengue NS1 antigen
Dengue Viral culture
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?
Immediate hospital admission
Home care with fluid monitoring and follow-up
Syrup ibuprofen 10mg/kg 12hourly
Start IV fluids
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?
Rising hematocrit
Increasing platelet count
Persistent vomiting
Urine output ≥1 ml/kg/hour
A 9-year-old child with dengue develops hypotension, cold extremities, and narrow pulse pressure. What is the MOST APPROPRIATE immediate fluid resuscitation dose?
10 mL/kg of NS over 1 hour
10 mL/kg of colloid over 1 hour
20 mL/kg of NS over 15–30 minutes
20 mL/kg of 1/2NSD5% over 15-30 minutes
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?
Progressive worsening of shock and lactate levels
Rising ferritin & worsening cytopenias beyond critical phase
Rapid improvement after additional fluid boluses
Presence of isolated transaminitis without cytopenias
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?
Give 1–2 pints of packed red cells immediately to improve oxygen delivery
Continue normal saline but treat for compensated shock ie increase the infusion rate to 10cc/kg.hr
Switch to a colloid such as Dextran or HES and run cautiously at5cc/kg/hr
Initiate 5% albumin infusion at 7 cc/kg/h
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?
Proceed with transfusion because falling Hct indicates hemorrhage
Do not transfuse; the Hct fall is dilutional, and multiple parameters have improved
Increase normal saline rate to maintain Hct >50%
Start inotropes immediately
What is the compound value imposed on medical practitioners who fail to inform or notify infectious diseases to the nearby district health office?
RM 100
RM 10000
RM 10
RM 1000
Below practices are NOT advisable for severe dengue in ICU, EXCEPT
Nasogastric tube insertion
Non invasive ventilation for UGIB
Arterial line insertion
Chest drain for pleural effusion
Indication for ICU admission for dengue patient EXCEPT
Seizure
Platelet 30,000
Severe lactic acidosis
Hemodynamic instability
As regards to Dengue in pregnancy, choose the RIGHT statement
Mild metabolic alkalosis
Hemoconcentration
Dengue infection is an indication for elective delivery
Respiratory alkalosis
Under the Act 154 (Akta Pemusnahan Serangga Pembawa Penyakit 1975), what is the compound value imposed if they are found breeding disease carrying insects?
RM 500.00
RM 1,000.00
RM 1,500.00
RM 2,000.00
