1

In a restrictive lung disease:

1

In order to diagnose an obstructive lung condition, the FEV1/FVC must be below ...

1

In an obstructive lung disease:

1

In an obstructive lung condition, the ❌ is reduced to a greater extent than the ❌, thus there is a reduced FEV1/FVC ratio.

FVC

FEV1

1

Increased lung compliance means that the lungs are ( easier, harder ) to stretch

1

Increased Pulmonary Compliance = ( Increased, Decreased ) difficulty in expiring

1

Lung Compliance is ( increased, decreased ) in COPD

1

Total lung capacity in COPD patients is ( increased, decreased ) due to ( hyperinflation, hypoinflation )

1

In COPD patients, dynamic airway compression is more likely to occur on active inspiration.

1

Pulmonary fibrosis causes a ( decreased, increased ) lung compliance and ( decreased, increased ) gas diffusion

1

A diabetic patient is admitted comatose, with a 2 day history of urinary frequency and vomiting. She is displaying deep, sighing breathing. Which of the following is most likely?

1

is the volume of air present in the lungs at the end of passive expiration

1

Functional Residual Capacity is about ( 2.2 litres, 3.2 litres, 1.6 litres, 0.8 litres ) in a young adult male.

1

A patient experiencing a pneumothorax is at risk of becoming hypotensive.

1

A 67 year old patient presents with shortness of breathness and coughing up green sputum regularly. They have a 40 pack year history of smoking. What is their FEV1/FVC ratio most likely to be?

1

Peripheral Chemoreceptors are only stimulated by which two of the following?

1

Mechanism of anxiety related hyperventilation:

1

In a patient with diffuse pulmonary fibrosis, what is the most likely FEV1/FVC ratio?

1

Kussmaul breathing is one of the hallmark signs of

1

A low oxygen level in the blood would likely bring about ( vasoconstriction, vasodilation )

1

In which foetal artery does the presence of oxygen cause vasoconstriction?
(It is a vasodilator in every other bodily artery)
Artery

1

A 28 year old woman, with a long history of anxiety presents complaining of tingling around her mouth and in her fingers, what will her blood gases likely show?

1

Hyperventilation causing Respiratory Alkalosis would cause a tingling sensation in the fingers due to a reduced level of free ( calcium, iron, zinc, potassium, sodium ) in the blood as it binds to albumin, thus reducing the only metabolically active form of this mineral in the body causing a deficiency state - which includes peripheral tingling.

1

An opioid overdose would cause which of the following ABG findings?

1

Hyoscine is a ( parasympathetic, sympathetic, histamine, noradrenaline, acetylcholine ) antagonist which reduces respiratory secretions in palliative care patients

1

Which two of the following leads are used to check the axis of an ECG?

1

If Leads I and aVF are ( positive, negative ) on an ECG (first deflection of QRS complex is ( up, down ) the way) then the axis of the ECG is considered to be normal

1

❌: Lead 1 is positive but aVF is negative
❌: Lead 1 is negative but aVF is positive

Right Axis Deviation

Left Axis Deviation
