Which of the following is the most appropriate antibiotic for this patient’s infected pressure ulcer?
Ceftriaxone
Ciprofloxacin
Clarithromycin
Flucloxacillin
Nitrofurantoin
Which of the following is the most appropriate antibiotic for this patient’s infected pressure ulcer?
Flucloxacillin
The patient has an infected sacral pressure sore. The infection is likely to be superficial with no extension to the underlying bone (which would be concerning for osteomyelitis). Along with cleaning and dressing the wound, culture swabs of the fluid should be taken so antibiotics can be tailored according to microbial sensitivities. Superficial infections are typically treated with oral antibiotics such as flucloxacillin as this is likely to provide coverage for gram-positive bacteria that reside on the skin surface, such as Staphylococcus aureus. As the patient is bed-bound, he should also be assessed for an air mattress.
A 59-year-old patient is referred to the Urology Clinic after an episode of visible haematuria. Two suspicious papillary lesions are subsequently excised from the bladder wall at cystoscopy, and histopathology confirms high-grade papillary transitional cell carcinoma (stage Ta) on both subsequent biopsies.
What is the most appropriate treatment?
Transurethral resection of bladder tumour followed by a single dose of intravesical chemotherapy
Transurethral resection of bladder tumour, followed by a six-week course of intravesical chemotherapy
Transurethral resection of bladder tumour, followed by a six-week course of intravesical bacille Calmette–Guerin (BCG)
Transurethral resection of bladder tumour combined with chemo-radiotherapy
Radical cystectomy and prostatectomy combined with chemo-radiotherapy

Treatment of high-grade tumours consists of TURBT combined with BCG. BCG is the main intravesical immunotherapy for treating early-stage bladder cancer.
An 85-year-old bedbound patient is seen regarding a wound under her left heel. She reports pain in the area and feels that things are gradually worsening. She is otherwise well in herself, with no fever. On examination, you note an area of erythema, measuring approximately 2 cm, under the left heel, with partial-thickness skin loss involving the epidermis. There is no necrotic tissue, discharge or offensive smell.
What is the most appropriate management?
Compression hosiery
Debridement
Oral flucloxacillin
Topical barrier cream and repositioning
Topical fusidic acid with hydrocortisone

A 23-year-old female presents to her General Practitioner with a six-week history of sweating, tremors and palpitations. The patient is eight months pregnant. She has no significant past medical history. On clinical examination, she is noted to have prominent eyes, a heart rate of 110 bpm and a small, diffuse goitre. Her laboratory investigations are as follows:
Investigation Result Normal value
Free T4 44 pmol/l 11–22 pmol/l
Free T3 15 pmol/l 3.5–5 pmol/l
Thyroid stimulating hormone (TSH) < 0.01 µU/l 0.17–3.2 µU/l
TSH receptor antibody (TRAb) 20 U/l < 0.9 U/l
Which of the following treatments should be prescribed?
Carbimazole
Thyroxine
Ibuprofen
Tri-iodothyronine
Propylthiouracil as part of a blocking-replacement regime

TSH receptor antibody (TRAb) 20 U/l < 0.9 U/l
Which of the following treatments should be prescribed?
Carbimazole
The primary concern with carbimazole use is the risk of agranulocytosis, necessitating immediate medical attention if infection symptoms emerge. In the third trimester of pregnancy, carbimazole can be safely administered.
Which of the following most accurately describes the mode of action of tamoxifen?
Progesterone receptor antagonist
Oestrogen receptor agonist
Selective oestrogen receptor modulator
Aromatase inhibitor
Progesterone receptor agonist
Which of the following most accurately describes the mode of action of tamoxifen?
Selective oestrogen receptor modulator
Tamoxifen is a selective oestrogen receptor modulator that exhibits dual effects on oestrogen receptors, acting as an anti-oestrogen in mammary epithelium. This makes it valuable for both the prevention and treatment of breast cancer. Specifically, it is indicated for treating oestrogen receptor-positive tumours in pre- and perimenopausal females. Additionally, as a prophylactic measure, it may be prescribed to women at moderate to high risk of developing breast cancer, particularly those with a notable family history of breast and ovarian cancer.
A 32-year-old man presented complaining of headaches and sweating, and was found to be hypertensive. Investigations confirmed the diagnosis of a phaeochromocytoma. He was treated with phenoxybenzamine before surgery.
What is the pharmacological property of phenoxybenzamine that makes it the most suitable treatment for a phaeochromocytoma?
Irreversible α-adrenoceptor antagonist
Irreversible α- and β-adrenoceptor antagonist
Reversible α-adrenoceptor agonist
Reversible α-adrenoceptor antagonist
Reversible β-adrenoceptor antagonist

A 40-year-old male with a history of intravenous drug abuse 21 years ago is referred by his doctor with abnormal liver function tests. He has significantly raised alanine aminotransferase (ALT). He tests positive for hepatitis C RNA and genotyping reveals genotype 1 hepatitis C. Liver biopsy reveals lymphocytic infiltration with some evidence of early hepatic fibrosis with associated necrosis.
Which of the following is the most appropriate treatment?
Direct acting antivirals (DAAs)
Interferon gamma
Ribavirin
Pegylated (PEG)-interferon α and ribavirin
PEG-interferon α with ribavirin and a protease inhibitor

Liver biopsy reveals lymphocytic infiltration with some evidence of early hepatic fibrosis with associated necrosis.
Which of the following is the most appropriate treatment?
Direct acting antivirals (DAAs)
Interferon-based treatment regimens are no longer recommended for HCV infection, as DAAs are now considered first-line treatment. DAAs target different stages in the HCV lifecycle and are successful for over 90% of people with HCV infection. The treatment is usually a once-daily oral tablet regimen for either 8 or 12 weeks and is most effective when given before the onset of cirrhosis.
