Acetaminophen
Acetaminophen ( 5 Questions)
A nurse is caring for a client who has arthritis and takes acetaminophen daily for pain relief. The client asks the nurse why acetaminophen does not reduce the inflammation in his joints.
Which of the following responses should the nurse give?
Acetaminophen works by blocking prostaglandins in your brain, but not in your peripheral tissues. Prostaglandins are substances that cause pain and inflammation. By blocking them in the brain, acetaminophen reduces the perception of pain, but does not affect the inflammation in the joints.
Acetaminophen does not inhibit the cyclooxygenase-2 (COX-2) enzyme, which is involved in the synthesis of prostaglandins. COX-2 inhibitors are a different class of drugs that can reduce both pain and inflammation.
Acetaminophen does not decrease the production of leukotrienes, which are another type of inflammatory mediator. Leukotriene inhibitors are used to treat asthma and allergic rhinitis.
Acetaminophen does not reduce the activity of natural killer cells, which are part of the immune system and can destroy infected or abnormal cells.
Natural killer cells are not directly related to pain or inflammation.

Choice B is wrong because acetaminophen does not inhibit cyclooxygenase-2 (COX-2) enzyme, which is involved in the synthesis of prostaglandins. COX-2 inhibitors are a different class of drugs that can reduce both pain and inflammation.
Choice C is wrong because acetaminophen does not decrease the production of leukotrienes, which are another type of inflammatory mediators. Leukotriene inhibitors are used to treat asthma and allergic rhinitis.
Choice D is wrong because acetaminophen does not reduce the activity of natural killer cells, which are part of the immune system and can destroy infected or abnormal cells.
