Q

Pulsus paradoxus definition

A

This is a decrease in pulse wave volume (ie not palpable) during inspiration. Despite its very confusing name, pulsus paradoxus is best measured by BP, with a fall of systolic blood pressure of >10 mmHg during the inspiratory phase.
Systolic blood pressure normally falls during quiet inspiration in normal individuals. Pulsus paradoxus occurs in conditions where intrathoracic pressure changes between inspiration and expiration are large such as severe acute asthma or exacerbation of COPD.

Q

Blood pressure measurement recommendations

A

Routine blood pressure should be measured in the sitting position when the patient is relaxed, following a short period of rest and preferably having avoided caffeine and smoking in the previous 2 hours (Hypertension Management Guide (HMG) p8). If the initial reading is high, repeat the measurement after 5 minutes of quiet rest.

Q

Normal blood pressure

A

<140 systolic and <90 diastolic

18
Q

Orthostatic hypertension definition

A

The consensus definition is a ‘sustained reduction of systolic blood pressure of at least 20mmHg or diastolic blood pressure of 10 mmHg within 3 minutes of standing’

19
Q

Which source of temperature measurement give the highest average reading

A

Rectal (0.4 to 0.5 C higher than oral)
Oral
Axillary (0.4 to 0.7 C lower than oral)

20
Q

Normal temperature range

A

Varies from person to person
Diurnal variation (usually lowest at 6am and peaks at 4-6pm)
Varies with age (becoming lower with increasing age)
Sex (women slightly higher than men)
Higher premenstrually
35.5-37.5 C

21
Q

Cardiac valve auscultation sites

A

Aortic valve - right of the sternal border in the second intercostal space
Pulmonary valve - left of the sternal border in the second intercostal space
Tricuspid valve - left sternal border in the fourth intercostal space
Mitral valve - the apex of the heart in the fifth intercostal space in the midclavicular line.

22
Q

Lung surface markings posterior
- oblique fissures

A

The oblique fissures start at the 4th thoracic vertebral spine posteriorly. They then travel diagonally down to the anterior edge of the lung at the 6th costochondral junction. The right and left oblique fissures divide upper and lower lobes of the lungs and are symmetrical.

23
Q

lung surface markings lateral
- base
- oblique fissures

A

Base - rib 10
To find the level of the 6th rib in the midaxillary line, ask your patient to fully abduct their arm, then follow the medial border of the scapula to the midaxillary line. This will be at the level of the 6th rib which overlies the oblique fissures, and the start of the transverse fissure on the right.

24
Q

Lung surface markings anterior
- oblique fissures
- transverse fissure
- base

A

Oblique fissure - 6th rib
Transerve fissure - 4th rib
Base - Rib 10

25
Q

What spinal level is the transverse umbilical line

A

L3

26
Q

What causes pectus carinatum?

A

(Pigeon chest) - sequalae of chronic respiratory disease in childhood, usually asthma

27
Q

What causes cushings syndrome?

A

Excessive stimulation of glucocorticoid receptors, most commonly iatrogenic, for example long term treatment with glucocorticoid for asthma.

28
Q

Examples of ACTH dependent cushings syndrome (3)

A
  1. Pituitary dependent bilateral adrenal hyperplasia (cushings disease)
  2. Ectopic ACTH syndrome (bronchial carcinoid, small cell lung cancer, pancreatic cancer)
  3. Iatrogenic (ACTH therapy)

  2. Major depressive illness
  3. Primary obesity

A

Cachexia
Pigmentation of palmar creases, elbows, gums, buccal mucosa, genital areas and scars (due to ACTH having melanocyte stimulating activity)

34
Q

What is pseudohypoparathyroidism?

A

A genetic condition which resembles hypoparathyroidism, but caused by inability to respond to rather than deficiency of parathyroid hormone. Major cause is defective G proteins required for signal transduction. Characterised by hypocalcaemia and hyperphosphataemia. It is commonly associated with short stature, obesity, short metacarpals and ectopic calcification.

Q

Hand and elbow changes in rheumatoid arthritis

A

Ulnar deviation of fingers
Wasting of small muscles

Swan neck deformity
Rheumatoid nodules
Olecranon bursitis
Z deformity

41
Q

Clinical features of systemic lupus erythematous

A
  • Raynauds phenomenom (caused by vasospasm, followed by period of cyanosis due to presence of deoxygenated blood, followed by rubor (redness) due to reactive hyperaemia
  • Butterfly rash
  • Livedo reticularis (livedo - a discoloured spot or patch on the skin, often due to passive congestion, reticularis - vascular response caused by dilation of subpapillary venous plexus as a result of increased viscosity of the blood and changes in the vessels that delay blood flow away from skin)
42
Q

A

Generalised disorder of connective tissue which affects the skin, internal organs and vasculature.
Clinical hallmark is sclerodactyly (flexion contracture of fingers and thickening of tendon sheath) in combination with raynauds phenomenom or digital ischemia.
