NMC OSCE Clinical Assessment Skills 2

Question 1

You are performing a 12-lead ECG. Where should the V4 electrode be placed?

Accepted Answer

Fifth intercostal space, mid-clavicular line

Answer

V4 is placed in the fifth intercostal space at the mid-clavicular line (left side). Correct placement is essential for accurate ECG interpretation. V1 and V2 are at the fourth intercostal space at the right and left sternal edges respectively. V3 is between V2 and V4. V5 and V6 are at the anterior and mid-axillary lines.

Question 2

When assessing fluid balance, which clinical sign most reliably indicates dehydration in an adult patient?

Accepted Answer

Reduced skin turgor when pinching the skin over the sternum or clavicle

Answer

Reduced skin turgor assessed over the sternum or clavicle (where age-related skin changes are less pronounced) is one of the most reliable clinical signs of dehydration. Other important signs include tachycardia, postural hypotension, dry mucous membranes, reduced urine output, and prolonged capillary refill time.

Question 3

A patient has a respiratory rate of 28 breaths per minute, is using accessory muscles, and has intercostal recession. Using the ABCDE framework, what does this assessment indicate?

Accepted Answer

The patient has significant respiratory distress requiring immediate intervention at the 'B' (Breathing) stage

Answer

A respiratory rate of 28, accessory muscle use, and intercostal recession are signs of significant respiratory distress identified during the 'B' (Breathing) assessment. Normal adult respiratory rate is 12-20 breaths per minute. These findings require immediate oxygen therapy, positioning (sit upright), and urgent medical review.

Question 4

When performing a pain assessment, which validated tool should be used for a patient who is unable to communicate verbally?

Accepted Answer

Abbey Pain Scale or FLACC scale (observational behavioural tools)

Answer

For patients who cannot self-report pain (unconscious, severe cognitive impairment, intubated), observational behavioural tools like the Abbey Pain Scale or FLACC scale assess pain through facial expressions, body movements, vocalisations, and physiological changes. Self-report tools like VAS and numerical scales require verbal communication.

Question 5

You are performing a peak expiratory flow rate (PEFR) measurement. What instructions should you give the patient?

Accepted Answer

Stand or sit upright, take a deep breath in, seal lips around the mouthpiece, and blow out as hard and fast as possible in one short sharp blast

Answer

PEFR measures the maximum speed of expiration. The patient should stand or sit upright, inhale fully, form a tight seal around the mouthpiece, and blow out as hard and fast as possible in a short, sharp blast. Three readings are taken and the best value recorded. It is not a measure of sustained expiratory flow.
