Q

What is the difference in thick and thin blood films investigating Malaria?

Study These Flashcards
A

Thick blood films

  • More sensitive
  • Used for detecting presence of malaria

22
Q

How do patients with COPD maintain their neural respiratory drive?

Study These Flashcards
A

Through hypoxic drive as there is chronic CO2 retention

23
Q

What is the SpO2 aim for patients with COPD?

24
Q

Which oxygen delivering system will give the tightest delivery control?

25
How does hypercalcaemia affect urinary frequency?
There is increased Ca2+ excretion in the urine which increases H2O excreted therefore increases urinary frequency
26
Which electrolyte imbalance will cause ventricular tachycardia?
Mg2+
27
What are the BLS guidelines for pulseless ventricular tachycardia in the hospital setting?
1. Defibrillate 2. Commence CPR 3. Defibrillate 4. After 2nd defibrillation administer adrenaline 5. Administer adrenaline every 3-5 minutes 6. After 3rd defibrillation, administer amiodarone
28
What is the function of atropine in cardiology?
It's administered in acute complete heart block
29
Why are the sigmoid and caecum more likely to under volvulus?
Because they're loosly attached to the mesentry
30
What are the signs on x-ray produced by sigmoid and caecal volvulus?
* Sigmoid- coffee bean sign * Caecum- embryo sign
31
How does damage to Wernicke's vs Broca's area manifest?
* Wernicke's (what?) lack of understanding of speech but patients will be able to speak in fluent non-sensical sentences * Receptive aphasia * Broca's (b-) lack of speech production but sound understanding * Expressive aphasia
32
How will damage to the arcuate fasciculus manifest?
Patients will be able to understand and produce speech, but speech repetition is poor
33

39
Which patients is carotid endartectomy considered in?
If they have \>70% stenosis of the carotid arteries
40
Which organism causes whooping cough?
Bordatella pertussis
41
What is an A wave (J waves)?
Backflow of blood up the superior vena cava due to atrial contraction
42
What is a C wave (J waves)?
Ventricular contraction causing the tricuspid valve to bulge causing a backflow of blood into the SVC
43
What is a V wave (J waves)?
Increased venous return to the right atrium occuring in late systole
44
What is an X descent (J waves)?
Atrial relaxation and filling
45
What is a Y descent (J waves)?
Blood flow from the right atrium to the right ventricle via an open valve
46
What is a cannon A wave (J waves)?
Backflow of blood into the SVC when the atria and ventricles contract at the same time, as the atria are contracting against a closed tricuspid valve Most commonly seen in complete heart block
47
What is the presentation of ankylosing spondylitis?
Lower back pain that improves as the day progresses
48
What is Schober's test?
* Patient standing straight * A mark made 5cm below the iliac crest and 10cm above the iliac crest * Patient leans forward and the distance between the two marks should expand to 21cm
