After assessing a patient for pain, the nurse concludes that the pain is caused by a mechanical stimulus. What should the nurse consider as a possible cause of this patient's pain?
1. muscle tear
2. burn
3. frostbite
4. myocardial infarction
Correct Answer: 1
There are three types of painful stimuli: mechanical, chemical, and thermal. Mechanical causes of pain include spasm, compression, or extreme muscle stretch or contraction. A muscle tear creates pain from a mechanical source. Myocardial infarction involves pain from a chemical source. Burn and frostbite involve pain from a thermal source.
