What is the Triad of Hypoglycemia (Whipple’s Triad)?

A
  1. Symptoms of hypoglycemia (Tachycardia, shaking, sweating, irritability/confusion, dizziness, sweet cravings, lethargy)
  2. Low serum glucose in the presence of the symptoms
  3. Restoration of normal glucose levels leads to the reversal/improvement of symptoms

Note: remember diabetes is the inability for the body to control blood sugar levels due to desensitization of the insulin receptors (alpha Langerhans) => these symptoms are often present in diabetes especially type 1

16
Q

What is caffeine used for in neonates?

A

Respiratory stimulant

17
Q

What is the difference between enteral and parenteral feeding? Which would be used and which would be ceased in necrotising enterocolitis of the newborn

A

Enteral feeding is a feeding tube such as nasogastric tube that goes through the digestive system
Parenteral feeding such as TPN bypasses the digestive system altogether and is directly inserted into the blood via IV
Enteral feeding is ceased during necrotising enterocolitis and can even instigate it as blood

18
Q

In a hemorrhage, what medication would you immediately begin administering? What is it’s MOA/class?

A

Trancxamic acid. Anti-fibronolytic agents.

19
Q

What is Coarctation of the aorta? What is usually used to confirm the diagnosis. What is the cheapest method of confirming this.

A

Narrowing of a certain part of the aorta
ECHO but it can be seen on routine chest Xray or CT angio

20
Q

Child comes in with a runny nose, sore throat, and dry cough. How would you determine if this is a viral or bacterial infection based on a blood test. What are the clinical symptoms of a bacterial infection?

A

1) Complete WBC count: Elevated in bacterial (leukocytosis) and normal/low in viral (leucopenia)
2) Differential WBC count: Increased neutrophils in bacterial vs increased lymphocytes in viral
3) C-reactive protein only indicates inflammation not infection: typically raised in bacterial and normal in viral
4) Procalcitonin: Elevated in bacterial, normal in viral
5) Blood cultures for bacterial, PCR for viral
Clinical symptoms: Bacterial would have high fever, localised pain, and a productive cough usually.

21
Q

Where is needle thoracocentesis placed?

A

2nd intercostal space, MCL

22
Q

Where is the chest drain inserted?

A

4/5th inctercostal space, MAL

23
Q

What medication would you give to reduce intracranial pressure in a patient with raised ICP?

A

Osmotic diuretic (mannitol)
Hypertonic saline

24
Q

In an emergency station on an infant (<1), where would you try to gain IV access for fluids? If that doesn’t work where would it be best to insert a line?

You give fluids and notice that perfusion is not improving. What else can you administer?

A

Antecubital fossa

Interosseous via the anterior tibia

Inotrope (epinephrine/adrenaline)

25
Q

In patients with reduced kidney function or kidney injury. What analgesics should not be used? why?

A

NSAIDS e.g. ibuprofen as they can cause further damage and interstitial nephritis

26
Q

In an emergency station, how would you treat hypoglycemia?

A

IV access/interosseous access with a bolus of 5-10% dextrose (more if younger) at 2ml/kg. followed by the Same concentrations used in maintenance using the 100-50-20ml/kg/day or 4/2/1 rule

27
Q

What is a suppository?

A

Delivering medication Par rectum. Patients may refer to it as the one specifically used to induce bowel movements

28
Q

You are in an emergency station, what antibiotics would you administer to a child

A

<8 weeks => triple therapy of amoxicillin, gentamicin, and cefotaxime
>8 weeks => cefotaxime only

29
Q

Emergency: What should you do a few minutes after
administering oxygen
administering a bolus of IV fluids
administering a bolus of 2ml/kg dextrose?

Q

A

shigella and SHEC - shigella toxin producing E.coli

33
Q

What is included in a U&E

A

Urea:

Urea is a waste product produced by the liver as a result of protein metabolism. It is filtered by the kidneys and excreted in urine. Elevated levels of urea in the blood may indicate kidney dysfunction.
Creatinine:

Creatinine is a waste product produced by the muscles. Like urea, it is filtered by the kidneys, and blood levels are a key indicator of renal function. Elevated creatinine levels can be a sign of impaired kidney function.
Electrolytes:

The electrolytes measured in a U&E test include:
Sodium (Na): Sodium is important for maintaining fluid balance and nerve function.
Potassium (K): Potassium is crucial for nerve and muscle function, including the heart.
Chloride (Cl): Chloride, along with sodium, helps maintain fluid balance.
Estimated Glomerular Filtration Rate (eGFR):

eGFR is a calculated value that estimates how well the kidneys are filtering waste from the blood. It is often reported alongside creatinine levels to provide a more comprehensive assessment of kidney function.

34
Q

What type of drug is dexamethasone? Where is it used?

A

Oral steroids used in the management of croup

35
Q

When asked for investigations, what should you always include

A
