A 53-year-old woman is having 3 to 6 hot flushes a day and experiences dyspareunia. It is 2
years since her last menstrual cycle. Her predicted cardiovascular risk score is 4%. She has
low bone density, an intact uterus, and no history of breast cancer. Which ONE of the
following treatments would be MOST suitable for this patient?
a. Oestrogen-only hormone replacement therapy
b. Ospemifene - a selective oestrogen receptor modulator
c. Combined oestrogen and progestin hormone replacement therapy
d. A selective serotonin reuptake inhibitor
e. Clonidine - an α2-adrenergic receptor inhibitor - ANSC
A weak sensory stimulus elicits an action potential in a nerve axon. During the repolarisation
and after hyperpolarisation phases of this action potential, all of the following statements are
true, EXCEPT:
a. K+ ions are leaving the axon
b. The membrane conductance for K+ reaches its peak value
c. The membrane potential reaches a more negative value than at rest
d. The same stimulus is likely to elicit another action potential
e. The voltage-gated Na+ channels are mostly inactivated - ANSD
, In bone remodelling:
a. Osteoprotegerin secretion increases calcium release
b. Osteoclasts secrete the osteoid seam
c. Osteoprotegerin inhibits RANKL stimulation of osteoclast activity
d. Osteoclasts secrete RANKL
e. RANKL increases collagen secretion at the resorption bays - ANSC
A 53-year-old menopausal woman has osteoporosis and is reporting night sweats and hot
flushes. She has a family history of breast cancer. Which ONE of the following classes of
drug is MOST SUITABLE to treat her symptoms?

d. Randomised control trial and numbers needed to treat
e.Cohort study and relative risk - ANSA
Transmission of a nerve impulse from a motor neuron to a skeletal muscle fibre:
a. Involves ionic currents (Na+, Ca2+) through gap junctions spanning the synaptic cleft
b. Requires the simultaneous arrival of action potentials from several motor neurons
c. Is initiated when acetylcholine binds to acetylcholinesterase
d. Requires vesicle fusion at the postsynaptic membrane
e. Activates a postsynaptic cation channel that binds acetylcholine - ANSE
In the initial assessment of patients diagnosed with colorectal cancer, which ONE of the
following is LEAST important?
a. Measurement of a CEA level
b. Exclusion of metastatic disease in the liver and lungs
c. Exclusion of rectal bleeding and bowel obstruction
d. Assessment of the patient's co-morbidities
