4In an obstructive lung condition, the [blank_start]FVC[blank_end] is reduced to a greater extent than the [blank_start]FEV1[blank_end], thus there is a reduced FEV1/FVC ratio.
- AFVC
- BFEV1
5Increased lung compliance means that the lungs are [blank_start]easier[blank_end] to stretch
- Aeasier
- Bharder
6Increased Pulmonary Compliance = [blank_start]Increased[blank_end] difficulty in expiring
- AIncreased
- BDecreased
7Lung Compliance is [blank_start]increased[blank_end] in COPD
- Aincreased
- Bdecreased
8Total lung capacity in COPD patients is [blank_start]increased[blank_end] due to [blank_start]hyperinflation[blank_end]
- Ahyperinflation
- Bhypoinflation
- Cincreased
- Ddecreased
9In COPD patients, dynamic airway compression is more likely to occur on active inspiration.
- ATrue
- BFalse
10Pulmonary fibrosis causes a [blank_start]decreased[blank_end] lung compliance and [blank_start]decreased[blank_end] gas diffusion
- Adecreased
- Bincreased
- Cdecreased
- Dincreased
11A 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?
- ApH 7.26 PCO2 3.2 HCO3- 8 PO2 12
- BpH 7.08 PCO2 5.2 HCO3- 8 PO2 11.8
- CpH 7.1 PCO2 7.1 HCO3- 26 PO2 10.2
12[blank_start]Functional Residual Capacity[blank_end] is the volume of air present in the lungs at the end of passive expiration
- AFunctional Residual Capacity
13Functional Residual Capacity is about [blank_start]2.2 litres[blank_end] in a young adult male.
- A2.2 litres
- B3.2 litres
- C1.6 litres
- D0.8 litres
14A patient experiencing a pneumothorax is at risk of becoming hypotensive.
- ATrue
- BFalse
15A 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?
- A20%
- B40%
- C60%
- D80%
- E90%
16Peripheral Chemoreceptors are only stimulated by which two of the following?
- APO2
- BH+
- CHCO3
- DH2O2
- EPCO2
17Mechanism of anxiety related hyperventilation:
- AIncreased work of breathing due to reversible airways obstruction
- BIncreased central and autonomic arousal
- CIncreased autonomic arousal
- DIncreased central arousal
- EStimulation of peripheral chemoreceptors
18In a patient with diffuse pulmonary fibrosis, what is the most likely FEV1/FVC ratio?
- A20%
- B40%
- C60%
- D80%
19Kussmaul breathing is one of the hallmark signs of
- ADiabetic Ketoacidosis
- BHyperglycemic Hyperosmolar State
- CHypertensive Crisis
- DHypotensive Crisis
20A low oxygen level in the blood would likely bring about [blank_start]vasoconstriction[blank_end]
- Avasoconstriction
- Bvasodilation
21In which foetal artery does the presence of oxygen cause vasoconstriction?
(It is a vasodilator in every other bodily artery)
[blank_start]Ductus Arteriosus[blank_end] Artery- ADuctus Arteriosus
22A 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?
- ARespiratory Alkalosis (High pH, Low CO2)
- BRespiratory Acidosis (Low pH, High CO2)
- CMetabolic Alkalosis (High Bicarbonate, High pH)
- DMetabolic Acidosis (Low Bicarbonate, Low pH)
23Hyperventilation causing Respiratory Alkalosis would cause a tingling sensation in the fingers due to a reduced level of free [blank_start]calcium[blank_end] 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.
- Acalcium
- Biron
- Czinc
- Dpotassium
- Esodium
24An opioid overdose would cause which of the following ABG findings?
- ApH 7.2, PC02 6.8. P02 8.2, HC03- 26
- BpH 7.36, PC02 6.8. P02 12.2, HC03- 38
- CpH 7.5, PC02 3.4, P02 6.9, HC03- 26
- DpH 7.5, PC02 3.4, P02 12.2, HC03-
25Hyoscine is a [blank_start]parasympathetic[blank_end] antagonist which reduces respiratory secretions in palliative care patients
- Aparasympathetic
- Bsympathetic
- Chistamine
- Dnoradrenaline
- Eacetylcholine
26Which two of the following leads are used to check the axis of an ECG?
- ALead 1
- BLead II
- CLead III
- DaVF
- EaVR
- FaVL
27If Leads I and aVF are [blank_start]positive[blank_end] on an ECG (first deflection of QRS complex is [blank_start]up[blank_end] the way) then the axis of the ECG is considered to be normal
- Apositive
- Bnegative
- Cup
- Ddown
28[blank_start]Left Axis Deviation[blank_end]: Lead 1 is positive but aVF is negative
[blank_start]Right Axis Deviation[blank_end]: Lead 1 is negative but aVF is positive- ARight Axis Deviation
- BLeft Axis Deviation
