Back Pain Low Back Pain And Vital Signs 4 — Questions and Answers
Question 1: An IV drug user presents with low back pain, fever of 102.5°F, and heart rate of 118 bpm. What is the highest-priority concern?
- Spinal epidural abscess (Correct answer)
- Muscle spasm from lifting
- Ankylosing spondylitis flare
- Poor posture
Correct answer: Spinal epidural abscess
IV drug use plus fever, tachycardia, and back pain strongly suggests a spinal epidural abscess.
Question 2: Which set of vital signs is most consistent with early sepsis in a patient with infectious back pain?
- Temperature 102°F, HR 124, RR 24, BP 92/58 (Correct answer)
- Temperature 98.6°F, HR 68, RR 14, BP 122/78
- Temperature 97.9°F, HR 60, RR 12, BP 130/85
- Temperature 99.0°F, HR 72, RR 16, BP 118/76
Correct answer: Temperature 102°F, HR 124, RR 24, BP 92/58
Fever, tachycardia, tachypnea, and hypotension together indicate a septic response.
Question 3: In chronic low back pain, vital signs are often normal because:
- The body physiologically adapts to persistent pain over time (Correct answer)
- Chronic pain destroys the sympathetic nervous system
- Chronic pain is always imaginary
- Blood pressure cannot change after age 40
Correct answer: The body physiologically adapts to persistent pain over time
Physiologic adaptation means chronic pain frequently produces no measurable vital sign changes.
Question 4: Before administering an NSAID such as ibuprofen for back pain, which vital-sign-related history is most important to review?
- Blood pressure history, since NSAIDs can raise blood pressure (Correct answer)
- Shoe size
- Hair color
- Handedness
Correct answer: Blood pressure history, since NSAIDs can raise blood pressure
NSAIDs can elevate blood pressure and worsen hypertension, so blood pressure history matters.
Question 5: A back pain patient's radial pulse is irregular at 112 bpm. What should be done next?
- Assess further, such as with an apical pulse or ECG (Correct answer)
- Ignore it because back pain explains everything
- Document it as normal
- Only recheck in one week
Correct answer: Assess further, such as with an apical pulse or ECG
An irregular tachycardia warrants further cardiac assessment regardless of the back pain complaint.
Question 6: Which vital sign finding would argue AGAINST simple mechanical low back pain?
- Temperature of 102.2°F (39°C) (Correct answer)
- Blood pressure of 118/76 mmHg
- Heart rate of 74 bpm
- Respiratory rate of 16 breaths per minute
Correct answer: Temperature of 102.2°F (39°C)
Fever is not caused by mechanical back pain and signals a systemic process.
Question 7: Why should vital signs be reassessed after giving pain medication for acute low back pain?
- To evaluate treatment response and detect adverse drug effects (Correct answer)
- Because insurance requires hourly weights
- To confirm the patient's identity
- Vital signs never change after medication
Correct answer: To evaluate treatment response and detect adverse drug effects
Reassessment confirms the medication worked and screens for side effects like hypotension or respiratory depression.
