Medical Knowledge Clinical Procedures 2 — Questions and Answers
Question 1: What are the 'five rights' of medication administration?
- Right patient, drug, dose, route, time (Correct answer)
- Right patient, drug, dose, nurse, chart
- Right medication, patient, family, chart, side
- Right drug, day, ward, hospital, name
Correct answer: Right patient, drug, dose, route, time
The five rights of medication administration are: right patient, right drug, right dose, right route, and right time.
Question 2: How is oxygen saturation measured non-invasively at the bedside?
- Arterial blood gas sampling
- Pulse oximetry (Correct answer)
- Capnography
- Spirometry
Correct answer: Pulse oximetry
Pulse oximetry uses light absorption differences between oxygenated and deoxygenated hemoglobin to estimate arterial oxygen saturation (SpO2).
Question 3: What does the SAMPLE mnemonic stand for in patient history taking?
- Signs, Allergies, Medications, Problems, Last meal, Events
- Signs, Assessment, Mechanism, Pain, Labs, Exam
- Symptoms, Allergies, Medications, Pertinent history, Last oral intake, Events (Correct answer)
- Situation, Allergies, Medications, Past history, Latest vitals, Events
Correct answer: Symptoms, Allergies, Medications, Pertinent history, Last oral intake, Events
SAMPLE stands for Symptoms, Allergies, Medications, Pertinent past history, Last oral intake, and Events leading to the complaint.
Question 4: What is the correct angle for a subcutaneous injection?
- 90 degrees always
- 45–90 degrees depending on tissue depth (Correct answer)
- 15 degrees
- 30 degrees
Correct answer: 45–90 degrees depending on tissue depth
Subcutaneous injections are typically given at 45 degrees in lean patients or 90 degrees when adequate subcutaneous tissue is present.
Question 5: What is the Glasgow Coma Scale (GCS) used to assess?
- Pain level using a numeric scale
- Neurological function and level of consciousness (Correct answer)
- Respiratory effort and oxygenation
- Cardiac output and hemodynamic status
Correct answer: Neurological function and level of consciousness
The GCS assesses level of consciousness based on eye opening, verbal response, and motor response, with total scores ranging from 3 to 15.
Question 6: What is the purpose of culturing a wound swab?
- Measure wound depth and dimensions
- Identify infecting microorganisms and their antibiotic sensitivities (Correct answer)
- Check for occult bleeding
- Assess tissue oxygenation and viability
Correct answer: Identify infecting microorganisms and their antibiotic sensitivities
Wound cultures identify the specific bacteria causing infection and guide targeted antibiotic therapy through sensitivity testing.
