1. The insulation on the power cord of a piece of class 1 equipment is faulty such that the active wire is in contact with the equipment casing. What will happen when the power cord is plugged in and the piece of equipment is turned on

A. The double insulation of the device will prevent macroshock when the outer casing is touched

B. The electrical fuse will immediately break and disconnect the device from the power supply

C. Equipotential earthing will prevent microshock

D. The Line Isolation Monitor will alarm and disconnect power to the device

E. The RCD will rapidly disconnect the device from the power supply

B. The electrical fuse will immediately break and disconnect the device from the power supply

Because the earthed equipment casing will provide a low resistance pathway for conduction resulting in high electrical current. This assumes that there isn't an isolation transformer in the circuit. There is also a fuse in the case.

Class I : Equipment in this class makes use of the wire from equipment case to earth to provide protection.

Class II equipment relies on at least two layers of insulation to provide protection.

Class III equipment uses low voltages provided by batteries or special power supplies to be "safe". Lower voltages are considered to be safer than high voltages.

"Kimand colleagues7 measured cTnI on the first 3 postoperative days in patients undergoing major vascular surgery; 12% had an elevated cTnI on routine postoperative surveillance although only 3% had AMI according to WHO criteria.They found that a raised cTnI was associated with a six-fold increased risk of death and a 27-fold increased risk of MI in the 6 months following surgery.There was a dose–response relationship between postoperative cTnI concentration and mortality. Landesberg and colleagues demonstrated a substantial increase in perioperative cardiac risk when even minor elevations in cTn occur in patients having undergone vascular surgery. A relationship existed between the finding of ischaemia with continuous ECG monitoring and elevations of troponin; the more prolonged the ischaemia the greater the cTn increase. Those with the greatest cTn concentrations had increased chance of a subsequent cardiac event and worse long-term mortality. Even minor elevations in cTn during first three postoperative days predicted increased risk."

A. Dopamine

B. Dobutamine

C. Noradrenaline

D. Adrenaline

E. Levosimenden

29. Which organ is least tolerant of ischaemia following removal for transplantation

A. Cornea

B. Heart

C. Liver

D. Kidney

E. Pancreas

B. Heart

Heart 4h

Lungs 6-8h

Liver/Pancreas 12h

Kidneys 18h

Different organs exhibit different tolerances to warm and cold ischaemia, in part related to the nature of the organ and in part because of the demands on the organ after transplantation. Hence the heart, which has to function immediately upon transplantation, has the shortest tolerance to cold ischaemia, and each hour beyond the first results in a measurable reduction in survival; it should ideally be transplanted in <4 h. This in turn mandates that heart retrieval cannot begin until a suitable recipient has been identified, admitted to transplant centre, and indeed prepared for surgery. Although lungs are slightly more tolerant, with good function to be expected as long as cold ischaemia is <6–8 h, similar principles very often apply. Kidneys, in contrast, need not work immediately and the recipient can be supported on dialysis until they do work. Nevertheless, there is an increased recognition that even kidneys fare better if transplanted as quickly as possible, and ideally within 18 h. The liver and pancreas lie in between and are best transplanted within 12 h.

A. Bisphosphates

B. Calcitonin

C. Frusemide

D. Sodium Chloride

E. IV crystalloids

A. Bisphosphonates

Bisphosphonates: inhibit osteoclast activity thereby causing a fall in plasma calcium. But, also produces a decrease in renal excretion of calcium.

Calcitonin: produced by parafollicular cells of the thyroid, acting to oppose the effects of parathyroid hormone. Works via 3 mechanisms: inhibition of intestinal calcium absorption, inhibition of bone osteoclast activity, and inhibition of renal tubular cell resorption of calcium, thereby increasing urinary excretion

Frusemide: potent loop diuretic acting at the Na/K/2CL cotransporter in the thick ascending limb of the loH. Twofold action: allows for aggressive fluid loading and also some effect on decreased renal calcium resorption. NaCl - Renal excretion of Na results in concurrent Ca excretion via increased RBF.

IVT - Increased renal Ca excretion

ACC/AHA PracticeGuidelines. Guidelines for the Management of Patients With Valvular Heart Disease: The normal mitral valve area is 4.0 to 5.0 cm2. Narrowing of the valve area to <2.5 cm2 must occur before development of symptoms. A mitral valve area>1.5 cm2 usually does not produce symptoms at rest. However, if there is an increase in transmitral flow or a decrease in the diastolic filling period,there will be a rise in left atrial pressure and development of symptoms.

D. In inspiration when increase is normal

E. In inspiration more than normal subjects

E. In inspiration more than normal subjects"

Under normal conditions, arterial blood pressure fluctuates throughout the respiratory cycle, falling with inspiration and rising with expiration. Therefore, during inspiration the fall in the left ventricular stroke volume is reflected as a fall in the systolic blood pressure. The converse is true for expiration. During quiet respiration, the changes in the intrathoracic pressures and blood pressure are minor. The accepted upper limit for fall in systolic blood pressure with inspiration is 10 mmHg. The “paradox” refers to the fact that heart sounds may be heard over the precordium when the radial pulse is not felt. This is due to an exaggeration of the normal mechanisms mentioned above. Moreover, the clinical method of assessment of this "pulse" is by measurement of the "systolic blood pressure".

TOTW 228 2011:

133. In a patient with severe rheumatoid arthritis, which radiological finding is most consistent with severe atlantoaxial instability (? C1/C2 instability)

A. A 9mm gap between the anterior arch of C1 and the odontoid peg

B. Increased saggital diameter

C. Posterior atlanto dental interval of > 14mm

D. Midpart of C1 over C2

E. Tear drop sign of C2

A. A 9mm gap between the anterior arch of C1 and the odontoid peg

Atlanto-axialinstability (AAI) occurs when subluxation or dislocation causes the odontoidprocess or posterior arch of the atlas to impinge on the spinal cord. Transverseligament holds dens against the anterior arch of C1, preventing anteriortranslocation of C1 on C2 (~80% AAI). Ondontoid prevents posteriortranslocation (~5%). Others due to vertical/lateral.

AAI defined asAADI of >3mm. >9mm is associated with inc risk neurological injury.Subluxation in upto 70% of RA pts, but only 25% dislocation. Due to synovial C1/2 joint, anddestruction of transverse ligament.

PADI is the distance between posterior surface of the odontoid and the anterior margin of the posterior ring of the atlas. At all cervical levels cord requires minimum canal width of 10mm; CSF 2mm, dura 2mm. Thus, minimum PADI of 14mm is needed to avoid cord compression

B. Associated with thymoma

C. Repeated exercise causes weakness to initially improve

D. Good response to edrophonium

E. Resistant to non-depolarizing muscle relaxants

C. Repeated exercise causes weakness to initially improve

The Eaton-Lambert Syndrome (ELS) is a rare condition in which weakness results from a pre-synaptic abnormality of ACh release at the neuromuscular junction. It is classically associated with small cell carcinoma of the lung although recent evidence suggests up to 50% may be free from underlying malignancy. The clinical presentation is that of proximal weakness with absent reflexes, sometimes with bulbar and facial muscle involvement. Importantly the weakness tends to improve with muscle contraction, unlikeMG. ELS treatment consists of treatment of underlying malignancy if present,improving neuromuscular transmission with drugs, and immunosuppression.
