Mr C, 47 years old has been diagnosed with COPD for a while. He does not smoke, after successfully adhering with the smoking cessation clinic run by the practice nurse. The GP has been reviewing his notes after another discharge letter arrived relating to a COPD exacerbation, his 5th this year. Mr C is on optimised inhaled therapies and is currently taking the following medicines for managing his COPD:
Trimbow pMDI®: 2 Puffs BD
Salbutamol 100mcg: 1-2 puffs QDS PRN
Carbocisteine 375mg: 2 TDS
The GP is looking to initiate a prophylactic antibiotic due to the frequent and prolonged exacerbations with sputum production.
Which of the following antibiotics would be most likely to be considered?
A. Amoxicillin 500mg – 1 TDS
B. Azithromycin 250mg – One 3 times per week
C. Azithromycin 250mg – 1 OD
D. Clarithromycin 250mg – One 3 times per week
Azithromycin 250mg – 1 OD
Bnf;
After considering if respiratory specialist input is required, considerazithromycin[unlicensed] prophylaxis to reduce the risk of exacerbations in patients who are non-smokers, have had all other treatment options optimised, and who continue to either have prolonged or frequent (4 or more per year) exacerbations with sputum production, or exacerbations resulting in hospitalisation. Ensure sputum culture and sensitivity testing, a CT scan of the thorax (to rule out other lung pathologies), a baseline ECG (to rule out QT prolongation), and LFTs are performed before offering prophylaxis. Review treatment after the first 3 months, then at least 6 monthly thereafter; only continue if benefits outweigh risks.

Mr P 31 years old, has been visiting the smoking cessation clinic at the practice. After a period of several months, he has successfully managed to quit smoking. The nurse refers him to the GP as she believes that a dosage adjustment may be necessary as a result of Mr P stopping smoking.
Which drug from below may require a dosage adjustment as a result of stopping smoking?
A. Theophylline
B. Montelukast
C. Salbutamol
D. Sodium Cromoglicate
smokingcause increase oftheophyllineclearance by 58–100% and decrease its half life (T/2) by 63% in thesmokersorganism compared with nonsmokers. This is because it is highly metabolized by CYP1A2.theophylline dose usually doubled if smoker.
Mr CP, who is 67 years old, is currently suffering from persistent breathlessness due to his COPD. He has already been previously prescribed and uses a salbutamol inhaler which is no longer controlling his symptoms. His FEV1 is 55%.
Which ONE of the following is the most appropriate treatment option?
A. Short-acting muscarinic antagonist
B. Domiciliary oxygen
C. Long acting beta2 agonist plus inhaled corticosteroid
D. Long acting muscarinic agonist
E. Long acting muscarinic antagonist plus long acting beta2 agonist plus inhaled corticosteroid
D
If FEV1 is greater than 50%, the next step would be to add a LAMA or a LABA alone.

Mrs M, who is 64 years old, has been admitted to hospital due to an infective exacerbation of COPD. She has been prescribed nebulised medication to relieve her symptoms. Nurse R commented on that certain nebulised medication can cause acute angle-closure glaucoma if the patients eyes are not protected.
Which ONE of the following medication is the nurse referring to?
A. Budesonide B. Ipratropium C. Salbutamol D. Fluticasone E. Terbutaline
Ipratropium
BNF Caution: Acute angle-closure glaucoma has been reported with nebulised ipratropium, particularly when given with nebulised salbutamol (and possibly other beta2 agonists); care needed to protect the patient’s eyes from nebulised drug or from drug powder.
Mr T is a 54-yo who has been admitted to hospital after persistent SOB and has been diagnosed with having an acute severe exacerbation of his COPD. He has been given a slow IV injection of aminophylline followed by a maintenance dose via IV infusion.
Which ONE of the following is the most appropriate plasma-drug concentration required for satisfactory bronchodilation?
A. 10-20 mcg/L B. 10-20 mg/L C. 55-110 mcg/L D. 20-30 mg/L E. 15-20 mg/L
B.
In most individuals, a plasma-theophylline concentration of 10-20mcg/ml or 10–20 mg/litre (55–110 micromol/litre) is required, although 5-15mcg/ml may be effective. ADR occur within 10-20mg/litre and both the freq and severity increase > 20mg/litre.
Aminophylline is a compound of the bronchodilator theophylline with ethylenediamine in 2:1 ratio. The ethylenediamine improves solubility, and the aminophylline is usually found as a dihydrate. Aminophylline is less potent and shorter-acting than theophylline.
An 11-year-old boy is admitted to hospital with an infective exacerbating of asthma. He has a past medical history of asthma, which has been well controlled until the development of infection. He is penicillin allergic. His current medication is as follow:
Salbutamol 100mcg MDI 2 puffs PRN
Seretide accuhaler 100 1 puff BD
Which of the following would be the most appropriate first line treatment?
A. Nebulised salbutamol with a course of prednisolone tablets
B. Nebulised salbutamol with dexamethasone oral solution
C. Nebulised salbutamol with hydrocortisone tablets
D. Nebulised salbutamol with SMART therapy
E. Nebulised terbutaline and nebuliser ipratropium
A. Nebulised salbutamol with a course of prednisolone tablets
SMART = Single Maintenance And Reliever Therapy
For acute asthma in children over 5 yo inhaled SABS are first line treatment. Oral steroids early in the treatment of acute asthma is extremely beneficial and can prevent hospital admission in emergency departments. Oral prednisolone is the steroid of choice.
Which of the following is classed as a “Loop Diuretic”?
A. Bumetanide
B. Amiloride
C. Metolazone
D. Bendroflumethiazide
Bumetanide = loop diuretic
Amiloride = k sparing diuretic
Metolazone = thiazide-like diuretic
Bendroflumethiazide = thiazide diuretic
Some beta-blockers are classed as “Cardio-selective”. These beta-blockers predominantly work on the B1 receptors in the heart.
Which of the following beta-blockers is not classed as “cardio-selective”?
A. Atenolol
B. Metoprolol
C. Nebivolol
D. Propranolol
Propranolol
Be A MAN
Atenolol,bisoprolol,metoprolol,nebivolol, and (to a lesser extent)acebutolol, have less effect on B2 (bronchial) receptors and are, therefore, relativelycardioselective, but they are notcardiospecific. They have a lesser effect on airways resistance but are not free of this side-effect.
Intrinsic sympathomimetic activity (ISA, partial agonist activity) represents the capacity of BB to stimulate AND block adrenergic receptors. Celiprolol, acebutolol,pindolol and oxprenolol have intrinsic sympathomimetic activity; they tend to cause less bradycardia and less coldness of the extremities.
You are discussing with the nursing team the number of patients who are coming into the surgery to get their INR tested due to being on warfarin. As part of a measure to try and reduce this you identify a cohort of patients who are eligible and willing to switch over to a DOAC.
One of the nurses asks what a patients INR should ideally be if they are to switch over to Apixaban from Warfarin straight away?
A. <2
B. <2.5
C. Between 2-3
D. >2.5
<2 INR
