A

Check for a DNR

53

A

Acetylsalicylic acid

54
Q

When inserting a nasopharyngeal airway, the bevelled edge should face ________

A

Medially

55
Q

Chemical control of respiration is triggered by the

A

rise of pCO2 in the body

56

Ascending aorta

57
Q
A
58
Q

The term abduction refers to movement of a body part…..?

A

Away from the midline

59
Q

Increased cell production in a normal tissue/organ is known as?

A

Hyperplasia

60
Q

What is the mechanism of action of aspirin in a suspected MI?

A

Inhibits platelet aggregation

61
Q

Passive stretching exerted by blood on the ventricular muscle at the end of diastole is referred to as…?

A

Preload

62
Q

The term automaticity refers to the ability of a cell to

A

Initiate an impulse on its own

63
Q

Two valves called the semilunar valves are the?

A

Pulmonary valve/ Aortic valve

64
Q

What is the typical tidal volume of a male patient?

A

500ml

65
Q

What tissue lines the trachea?

A

Epithelial

66
Q

For resting potential in a cardiac cell to exist, there must be an….?

A

Adequate number of potassium ions inside the cell and sodium ions outside the cell

67
Q

Under normal conditions, the strength of cardiac contraction is regulated by

A

The frank-sterling mechanism

68
Q

What is the frank sterling mechanism?
not an MCQ question but you should probably learn it you dumb bitch

A

Force of contraction of the heart muscle is directly proportional to the initial length of the muscle fibres.

KP: the more the heart muscle stretches during filling (diastole) the more forcefully it contracts during pumping (systole)

69
Q

What is a tension pneumothorax?

A

Air accumulates in the pleural space and becomes trapped, creating a one way valve effect

Causes: trauma/perforation in the lung parenchyma

70
Q

What is a simple pneumothorax?

A

AKA: collapsed lung
Occurs when air leaks into the pleural space. This air causes the lung to partially/fully collapse

Difference to tension:
There is no one way valve effect->air can escape the pleural space preventing a buildup of pressure

71
Q

What is spontaneous pneumothorax?

A

A collapsed lung that happens without an injury

TYPES
Primary spontaneous pneumothorax: no underlying health condition/disease. Can happen if abnormal air pockets in the lung (blebs) break apart and release air

Secondary spontaneous pneumothorax: caused by certain lung diseases. Lung becomes blocked, causing bulging areas (bullae) that can burst

72
Q

What is affinity (as it applies to pharmacology)

A

Attraction between a medication and its receptor

73
Q

How long is a pulse check on a hypothermic patient

A

30-45s

74
Q

CPAP should be started at which pressure?

A

5cm H2O

75
Q

What year was PHECC established

A

2000

76
Q

What is diffusion?

A

A substance moves from an area of higher concentration to an area of lower concentration without the use of energy

77
Q

The PR interval on an ECG starts where?

A

Start of the P wave

78
Q

What are the two laws relevant to respiration?

A

Henry’s Law: how partial pressure causes oxygen uptake and carbon dioxide release
LUNGS->BLOOD (O2)
TISSUE->BLOOD (CO2)

Boyles law: pressure and volume are inversely proportional. As one increases, the other decreases.
The difference in pressure between the atmosphere and the lungs drives the flow of air

79
Q

What are barbiturates?

A

CNS depressants

80
Q

What process is used when glucose enters a body cell?

A

Facilitated diffusion

WTF is that?
It’s a type of passive transport that allows molecules to move across a cell membrane with the help of specialised proteins

What does that actually mean?
Imagine ur wanna go to the club but the bouncer says no cuz ur a loser (in this scenario ur glucose)
Then ur mate (who’s a regular and a bestie with the bouncer pulls up- ur mates the protein)
The bouncer (the membrane) will let you in only if you’re with your super cool protein mate, so you tag on and into the club you gooooo💃🕺🏼💃

81
Q

The partial pressure of oxygen is….in atmospheric air?

A

159mmHg

82
Q

Integumentary also refers to what?

A

THE SKIN

83
Q

When stimulated, baroreceptors cause the heart rate to …..

A

DECREASE

84
Q

What are organelles?

A

Found within the cells cytoplasm and operate in a cooperative and organised fashion to maintain life of the cell

85
Q

GTN does what to the heart?

A

Reduces preload

86
Q

The normal duration of the QRS complex is?

A

0.04-0.12s

87
Q

The pressure in the left ventricle at the end of diastole is the….

A

Preload

88
Q

Administration of what drug may cause dizziness?

A

Glucagon

89
Q

What airway is contraindicated when there is peri orbital bruising and bruising behind the ears?

A

NPA

90
Q

What is an effector neuron?

A

Motor neuron - sends signal from CNS to Effector organs

91
Q

What is an afferent neuron?

A

Sensory neuron- signal from body to CNS

92
Q

What is an effector organ?

A

Structures that respond to nerve impulses from CNS

93
Q

A

CSF
