24
Q

Meningitis Symptoms

A

Viral:
Fever, headache, nausea and vomiting, photophobia and neck stiffness.
Bacterial:
Focal neuro deficits, gait/balance problems and hearing problems.
Bacterial is generally a quicker onset

25
Q

Encephalitis

A

Inflammation of the brain parenchmya tissue associated with clinical evidence of neurological dysfunction.

26
Q

Encephalitis symptoms

A

Altered conscious state, seizures, cranial nerve palsies, speech problems, motor and sensory deficits.

27
Q

Allergic reactions

A

Same pathophysiological pathway as IgE mediated immune response seen in anaphylaxis but does not progress to involving the respiratory, cardiovascular or gastrointestinal systems.

28
Q

Anaphylaxis definition

A

Any acute hypersensitivity reaction with typical skin features plus the involvement of respiratory and/or cardiovascular and/or persistent severe gastrointestinal symptoms or any acute onset of hypotension or bronchospasms or upper airway obstruction where anaphylaxis is considered possible ever if typical skin features are not present.

29
Q

Anaphylactoid reactions

A

Are immediated systemic reactions that mimic anaphylaxis but are not caused by IgE-mediated immune response.
Termed ‘non-immunologic anaphylaxis’.

30
Q

Anaphylaxis Pathology

A
  1. Increased capillary permeability 2. Increased smooth muscle contraction
  2. peripheral vasodilation
31
Q

Anaphylaxis symptoms

A

flushing, hives, angioedema, stridor, wheezing, vomiting, diarrhoea or hypotension.

32
Q

Biphasic reactions

A

A recurrent reaction or appearance of new symptoms after the initial allergy-related presentation without further exposure to the causative agent.

33
Q

Adrenaline use in anaphylaxis

A

Creates vasoconstriction, increases blood pressure, causes bronchodilation, stabilises mast cell membranes- reducing vasoactive mediators, and fluid therapy increases circulating intravascular volume.

34
Q

Toxicology definition

A

The scientific discipline of the nature, effects and detection of poisons and the treatment of poisonings.

35
Q

Poisonings

A

When people drink, eat, breathe, inject or touch enough of a hazardous substance (poison) to cause symptoms of illness or progression to death.

36
Q

Symptoms of Opioid overdose

A

Euphoria, drowsiness, unconsciousness, respiratory distress, bradycardia, hypotension and pupillary constriction.

37
Q

Psychostimulant symptoms

A

agitation, panic, behavioural disturbances, psychosis, hyperthermia, hypertension, tachycardia/arrhythmias, hyponatremia, hyperkalemia, hypoglycaemia.

38
Q

Tricyclics Antidepressants (TCA) symptoms

A

CNS depression (blockage of muscarinic receptors), coma, dilated pupils, respiratory depression, slurred speech, twitching movements, seizures, and arrhythmias.

39
Q

Sedatives (Benzos/ETHOH) symptoms

A

CNS depression, altered conscious state, slurred speech, respiratory depression, bradycardia, hypotension and seizures.

40
Q

Sedatives (GHB) symptoms

A

Irregular or shallow breathing, hallucinations, euphoria followed by coma, confusion, irritation and agitation, vomiting.

41
Q

Paracetamol overdose symptoms

A

No clinical manifestations of an overdose until fatal liver damage 1-3 days post ingestion.

42
Q

Insulin defined

A

Release is stimulated by increased serum glucose levels, the amino acids arginine and lysine free-fatty acids and parasympathetic stimulation. Released from beta cells.

43
Q

Glucagon defined

A

Acts primarily in the liver, stimulation glycogenolysis and gluconeogensis in response to hypoglycaemia, resulting in increased blood glucose. Released from alpha cells.

44
Q

Type 1 Diabetes

A

Autoimmune disease of unknown cause which results in the destruction of pancreatic B cells in the islets of Langerhans resulting in cessation of insulin production.

45
Q

Type 2 Diabetes

A

Progressive disease that sees the body become resistant to the normal effects of insulin (insulin resistant) and/or an insulin secretatory defect that may also be associated with or without insulin resistance.

46
Q

Hypoglycaemia Symptoms

A

Headache, tremors, aggression or agitation, altered conscious state or be complete unresponsive, diaphoresis, pallor, poor perfusion and occasionally may see seizures.

47
Q

Hyperglycaemia- DKA

A

Kussmal’s respirations, ketotic breath smell, hypovolemia and dehydration, polyuria, polydipsia, polyphagia, elevated BSL, ALOC, fatigue and abdominal pain/nausea and vomiting.

48
Q

Diabetic Ketoacidosis

A

Associated with type 1 diabetes (normally). Secondary to insulin deficiency hyperglycaemia results in peripheral glucose uptake does not occur and leads to fat breakdown by cells. Fat metabolism then occurs instead of carbs. Leads to ketones bodies and an acidotic state.

49
Q

Hyperglycaemia - Hyperosmolar syndrome (HHS)

A

Gradual onset over a period of weeks, generally associated with type 2. Characterised by hyperglycaemia and high plasma osmolality. Ketone bodies are not present because in most cases enough insulin exists.

50
Q

Appendicitis

A

Develops secondary to bacterial invasion of the appendiceal opening due to obstruction. If left untreated can lead to rupture into the peritoneal space.

51
Q

Appendicitis Symptoms

A

Onset of periumbilical pain, loss of appetite, followed by RLQ pain, nausea and vomiting.

52
Q

Bowel obstruction

A

Can be either mechanical (blockage within the lumen) or non-mechanical (muscle activity problem). Obstruction sees accumulation of gastric contents above the point of obstruction, bowel oedema and increased capillary permeability then occurs.

53
Q

Bowel obstruction symptoms

A

Colic, cramping pain that comes in intermittent waves, abdominal distention, diffuse tenderness, rigidity and constipation also occurs.
Fever, tachycardia and hypotension may also be noted in the VSS.

54
Q

Cholecystitis

A

Inflammation of the gallbladder following bacterial invasion or in most cases the development of gallstones.

55
Q

Cholecystitis symptoms

A

Pain usually develops post consumption of fried or fatty foods. Sudden onset abdominal pain, intermittent in nature and variable intensity. Radiation of pain from epigastrium to the RUQ, localised and rebound tenderness may also be elicited during palpation. Low grade fever, tachycardia, nausea and vomiting and flatulence.

56
Q

Pancreatitis

A

Inflammation of the pancreas which can develop from numerous causes.

57
Q

Pancreatitis symptoms

A

Pain usually located in the epigastric region with radiation through the back, dull and steady quality. Abdominal tenderness, distension, rebound discomfort and guarding. Fever, tachycardia, tachypnoea, hypotension and decreased/absent bowel sounds may be noted.

58
Q

Gastroenteritis symptoms

A

Nausea, vomiting, diarrhoea, abdominal cramps, hyperactive bowel sounds.
Fever, headache and other clinical signs of dehydration.
