Worksheet time: 21mins
All patients with warning signs should be started on intravenous hydration.
True
False
Raised hematocrit is always a sign if plasma leakage
True
False
In a hemodynamically stable patient with warning sign, increased oral fluid intake may be sufficient
True
False
Graded fluid regime for dengue should be started for all patients with warning sign(s)
True
False
Adjustment of maintenance fluid is needed during critical phase of dengue
True
False
Colloid is a preferred choice for fluid resuscitation
True
False
Excessive and prolonged fixed fluid regime in stable patient is detrimental to patient
True
False
Maintenance fluid for obese patient can be calculated using ideal body weight
True
False
Intravenous fluid should be continued until patient can be discharged
True
False
Fluid therapy has to be judiciously controlled to avoid fluid overload
True
False
The levels of excess lactate correspond to severity of circulatory failure
True
False
Lactate level of more than 5 mmol/L prognosticates a fatal outcome
True
False
The clearance of lactate is predominantly by the kidneys
True
False
Raised lactate levels equals to more aggressive fluid resuscitation each time
True
False
The physiological lactate concentration in the blood is between 2 to 2.5 mmol/L
True
False
For patients with dengue shock syndrome
serum lactate is elevated
serum lactate dehydrogenase is elevated
Lactate can be used as a predictor of Dengue Shock Syndrome if the level>2 mmol/L on day 0
Serum lactate has no limitations
Admission lactate more than 2mmol/L is a significant independent predictor of mortality
The following are true about FBC findings in early dengue infection
Patient often present with anemia
Platelet count may be normal
Lymphocytosis is a frequent presentation
Haematocrit is normal
There is progressive lowering of WBC
For patients with suspected dengue fever
Sample for NS1 antigen is best taken on D1-D10 of infection
Dengue is ruled out if NS1 is negative
IgM positivity during D5-10 of fever indicates a primary infection
IgG is detectable 1-2 days after the onset of symptoms in secondary infection
Capillary blood sample may be used for diagnosis
The following findings may be present in dengue shock syndrome EXCEPT
Hepatomegaly
Pleural effusion
Thrombocytopenia
Increase pulse pressure of > 20 mmHg
Which of the following statements regarding investigations for dengue is TRUE:
Baseline haematocrit (HCT) and white cell count should be taken after Day 3 of febrile illness if suspected dengue infection
Serial full blood count and HCT must be monitored as dengue infection progresses
Dengue Combo Rapid Test should be done only once
Negative IgM taken before day 5-7 of illness can exclude dengue infection
Below are dengue warning signs
Abdominal pain
Unprovoked epistaxis
Raised HCT with concomitant drop in platelets
Lethargy
Criteria of severe dengue
Severe plasma leakage
Severe thrombocytopenia
Severe bleeding
Severe organ involvement
