Q

Patient has had 20mls of lidocaine 0.5%. Max is 3mg/kg and he weighs 80kg. How much more can you give?

A

28ml

0.5% = 0.5g in 100 ml

Therefore the 20mls of that solution that he’s already been given, must contain 0.1g of lidocaine (or 100mg)

Max is 3mg/kg which means for him max is 240mg. So 240mg-100mg = 140mg left.

Then 20/100x140= 28mL

A

Shock

Unstable VT

If the patient has adverse signs (systolic BP < 90 mmHg, chest pain, heart failure, syncope) then immediate cardioversion is indicated. In the absence of such signs antiarrhythmics may be used. If these fail, then electrical cardioversion may be needed with synchronised DC shocks

Drug therapy

amiodarone: ideally administered through a central line
lidocaine: use with caution in severe left ventricular impairment

Q

Woman aged 40(ish) with T2DM. Her BMI is 28 and HBA1C is raised (?64). What management
plan?


A

Is this q saying she’s newly dx or has had DM for ages- cos that changes it since you’d probs start with ddiet as always:
a patient is newly diagnosed with HbA1c and wants to try lifestyle treatment first. You agree a target of 48 mmol/mol (6.5%)

But if she’s had the chance to change HBA1C with diet and not worked then surely whack her on Metformin?

metformin is still first-line and should be offered if the HbA1c rises to 48 mmol/mol (6.5%)* on lifestyle interventions

104
Q

SCC of tonsillar primary

A

HPV 16

105
Q

Which metastases are sclerotic to spine?

A

Prostate Cancer

Sclerotic bone metastases: These are also known as blastic bone metasteses. Prostate carcinoma
is the most common. Breast carcinoma may cause a mixed picture.

106
Q

Patient with sx of Guillain Barre. What Ix to monitor respiratory function?

A

In the investigation of Guillain Barre spirometry is important. Forced vital capacity is a major
determinant of the need for admission to ICU and then the need for intubation. This should be
measured 4 hourly.

107
Q

Man with sx of BPH. What treatment?

A

Medical management is suitable for mild BPH. Alpha-blockers (Tamsulosin) is 1 st line and
decreases smooth muscle tone of the bladder and prostate. 5 Alpha reductase inhibitors
(Finastride) is second line which decreases the conversion of testosterone to
dihyodroxytestoreone. Surgical management with TURP is only indicated for severe BPH.

108
Q

Woman with vaginal discharge – which Ix?

A

Patients who present with symptoms suggestive of bacterial vaginosis or vulvovaginal candidiasis
can be treated without sampling. Otherwise, swabs should be taken. Endocervical Swab in
transport medium (charcoal or non-charcoal) to diagnose gonorrhoea. Endocervical swab for a
chlamydial DNA amplification test to diagnose chlamydia. NB: a high vaginal swab (HVS) is only
worthwhile where there are recurrent symptoms, treatment failure, or in pregnancy,
postpartum, post-abortion or post-instrumentation.

109
Q

Woman with vaginal discharge. Diagnosis?

A

Most common cause of PID is chlamydia infection hence discharge may be indicative of this.

110
Q

Man with diabetes hypertension atherosclerosis etc. Cause of erectile dysfunction?

A

Erectile Dysfunction: This occurs as a result of autonomic neuropathy for which the most
common systemic cause is diabetes. This presents as impotence, ejaculatory failure and female
sexual dysfunction.

111

Q

Man comes with 48hr chest pain. ECG normal – what do you do?

A

Troponin

114
Q

AAA found by GP on examination. What Ix?

A

Ultrasound is simple and cheap; it can assess the aorta to an accuracy of 3 mm. It is used for
initial assessment and follow-up. CT provides more anatomical details, eg it can show the visceral
arteries, mural thrombus, the 'crescent sign' (blood within the thrombus, which may predict
imminent rupture), and para-aortic inflammation. CT with contrast can show rupture of the
aneurysm.

115
Q

Woman receives blood transfusion then gets pain in lower back. Problem?

A

Acute haemolytic transfusion reaction: Occurs due to ABO incompatibility, in which compliment
becomes activates and results in DIC. Symptoms include back pain, bloody urine, chills, fainting,
dizziness, fever, flank pain and flushing of skin.

116
Q

Patient with hearing loss. Then gets a lump in posterior triangle of neck. What’s the cause?

A

Cancer of the nasopharynx is most likely to cause a lump in the neck, but may also cause nasal
obstruction, deafness and postnasal discharge.
Answer: Nasopharyngeal Cancer

117
Q

Low Ca and High Phosphate in Chronic Renal Failure. Reason?

A

Lack of hydroxylation of Vitamin D

Renal Osteodystrophy: This occurs due to decreased excretion of phosphate by the damaged
kidneys. Low activate vitamin D levels are a result of the damaged kidneys’ ability to convert
vitamin D into its active form, calcitrol, and result in further hypocalcaemia. The body is therefore
unable to absorb calcium from the intestines and subsequently removes it from the bones.

118
Q

Spherocytes in blood film. Diagnosis?

A

Spherocytosis is an auto-hemolytic anemia characterised by the production of red blood cells that
are sphere-shaped, rather than bi-concave disk shaped. Spherocytes are found in hereditary
and autoimmune hemolytic aneamia.

119
Q

OD dilated pupils. Cause?

A

Amitriptyline Overdose: Commonly include sinus tachycardia, hot dry skin, dry mouth and
tongue, dilated pupils and urinary retention. The most important ECG feature of toxicity is
prolongation of the QRS interval, which indicates a high risk of ventricular tachycardia.

Antidote = intravenous sodium bicarbonate

120
Q

A 24-year-old female presents with worsening headache, fever, and double vision. Her headache is located in the periorbital region. Medical history is significant for a left-sided mid-facial furuncle which she attempted to squeeze over one week prior. On physical exam, there is bilateral supraorbital edema, lateral gaze palsy, ptosis, mydriasis, and chemosis?

A

Cavernous Sinus Thrombosis

Symptoms

  • fever
  • periorbital edema
  • headache

Physical Symptoms

  • cranial nerve palsies
  • first involve CN 6 as it runs through the middle of the sinus
121
Q

Dorsum of Great Toe sensory loss?

A

L5

122
Q

Patient with ascites and R swollen leg which ca?

A

Pelvic masses are most likely to cause localised compression of the large veins and subsequent
oedema of a unilateral limb. Of the malignancies given only ovarian cancer occupies the pelvis. It is
commonly associated with ascites (i.e. Meig’s Syndrome)

123
Q

Young man with urethritis and obstructive urinary sx?

Urethral Stricture - Urethritis due to gonorrhoea or Chlamydia can result in urethral stricture which is
the commonest cause in young men.

124
Q

Patient has sx of COPD, partial response to salbutamol inhaler? What Ix?

A

Diagnosis:According to NICE guidelines diagnosis in a symptomatic person should be confirmed using

  • *post-bronchodilator spirometry**. Additional investigations include CXR (to exclude other
    pathologies) , FBC (to identify anaemia or polycythaemia) and BMI.
125
Q

Tender hepatomegaly, raised JVP, ascites, AF. Ca-125 is 40. Cause?

A

Heart Failure

A normal range for Ca 125 is less than 35 U/ml therefore only slightly elevated. Ca 125 is generally a
non-specific marker and only useful in monitoring people who have a known diagnosis of ovarian
cancer, screening for recurrence.

126
Q

Lymph node biopsy had 5% larger cells?

A

Not enough information here. Lymph node biopsies are commonly done for Hodgkin and _Non-
Hodgkin lymphomas
_, the latter having a particular subtype associated with large cells (Diffuse Large
Cell Lymphoma). The only other blood cancer associated with large cells is CLL in which blasts are
commonly found, however this is seen on blood film and not lymph node biopsy.

127

A

Nicotinic acetylcholine receptor autoantibodies

(lambert eaton = presynaptic calcium channels)

133
Q

Bloods show really high K, and really low Ca. Cause?

A

Haemolysed Sample

Pseudohyperkalaemia occurs in haemolysed blood samples. In terms of both pseudohyperkalaemia
and pseudohypocalcaemia, I could only find one resource which states identifies both of these
electrolyte abnormalities together and occurs when the sample is contaminated with incorrect EDTA
bottles. I doubt this is what King’s is looking for

134
Q

Cr high, Urea high, PTH high, Ca high, Phosphate high. Myeloma? Hyperparathyroidism?

A

Answer: Hyperparathyroidism

Multiple Myeloma: This is a cancer of plasma cells in the blood. This is commonly associated with
hypercalcaemia due to the formation of lytic lesions within the bone causing systemic release of
calcium. Renal failure is also a common feature of MM. I could not find any data on parathyroid
hormone levels but having researched the mechanism of action you’d expect to see low levels of
PTH.

Hyperparathyroidism: This will obviously cause hypercalcaemiaand high levels of phosphate in urine
(although low levels will be seen in the serum). Renal calcium stones can possibly develop into renal

135
Q

Gram positive cocci in capsule?

A

Streptococcus Pneumoniae

136
Q

Menorrhagia in woman, and arising from pelvis?

A

Fibroids

137
Q

Woman has low Hb and low MCV, and doesn’t want blood transfusion during op? What can you
offer?

A

Cell salvage: This is autologous transfusion of blood collected within the procedure itself, it can be
given back during the procedure or after the procedure. One possible concern is that in operations
to remove cancers, tumour cells may be found in the blood salvaged which is highly unfavourable.

138
Q

Woman undergoes hysteroscopy, when would you do hysterectomy?

A

To save her life

139
Q

Lady being treated with Chemo and she gets sepsis signs. Diagnosis?

A

Neutropenic Sepsis

140
Q

Bowel obstruction post op and vomiting. What do you do first?

A

Adenocarcinoma: (Non-small cell carcinoma) Arise from mucous cells in bronchial epithelium. Most
common bronchial carcinoma associated with other asbestos and is more common in non-smoker
compared to other cell types. Invasion of the pleura and mediastinal lymph nodes is common.

Squamous cell carcinoma: (Non-small cell carcinoma) Associated with PTH secretion. Most present
as an obstructive lesion of the bronchus, leading to infection. Local spread is common.

Small cell carcinoma: Rapidly growing and highly malignant cells growing around bronchus. They are
found with metasteses on diagnosis. Particularly associated with SIADH, hypercalcaemia, ACTH and
gynaecomastia. Also associated with Eaton Lambert syndrome.

145
Q

Pt is in AF, what’s the most easily avoidable complication?

A

Complications of AF include systemic embolism, precipitation of acute heart failure, worsening of
existing heart failure and development of cardiomyopathy. The most easily avoidable is systemic
embolic with anticoagulant medication such warfarin, rivaroxiban and dabigatran.

Man with BPAD falling over what making him fall?

A

Lithium toxicity is associated with dizziness, ataxia, inco-ordination, muscle twitching and tremor.

Other manifestations of lithium toxicity include anorexia, diarrhoea, vomiting, drowsiness, apathy,
restlessness and dysarthria. Severe toxicity may result in hyperreflexia, convulsions, collapse, coma,
renal failure, dehydration, circulatory collapse, hypokalaemia and death.

149
Q

Male presents with acute severe unilateral pain in eye blurred vision and pupils dilated. Whatwould you expect on Ix?

A

Acute angle-closure glaucoma: Acutely raised intraocular pressure. This commonly presents with
rapidly progressive pain which may be confined to one eye but usually spreads to the other. There is
rapid blurring of vision and colour halo around lights. Mid-dilated pupils may be a causative factor.
