What is an example of a client's primary defense to infection?

Choice A reason: Polyuria is the production of abnormally large amounts of urine, which can be caused by various factors, such as diabetes, kidney disease, or diuretics. Polyuria is not an expected finding in a client with inflammation, which is the body's response to injury or infection. Inflammation does not affect the urinary system directly, unless the inflammation is located in the kidneys or bladder.

Choice B reason: Edema is the swelling of tissues due to excess fluid accumulation, which can be caused by various factors, such as heart failure, liver disease, or venous insufficiency. Edema is not an expected finding in a client with inflammation, which is the body's response to injury or infection. Inflammation does not cause fluid retention, but rather fluid leakage from the blood vessels into the interstitial spaces.

Choice C reason: Heat is an expected finding in a client with inflammation, which is the body's response to injury or infection. Heat is caused by the increased blood flow to the inflamed area, which brings more oxygen and nutrients to the damaged tissues. Heat also helps to kill or inhibit the growth of microorganisms that may cause infection.

Choice D reason: Erythema is an expected finding in a client with inflammation, which is the body's response to injury or infection. Erythema is the redness of the skin due to the dilation of the blood vessels in the inflamed area, which increases the blood flow and the delivery of oxygen and nutrients to the damaged tissues. Erythema also helps to signal the presence of inflammation and attract immune cells to the site.

Choice E reason: Pain is an expected finding in a client with inflammation, which is the body's response to injury or infection. Pain is caused by the stimulation of the nerve endings by chemical mediators, such as histamine, prostaglandins, and bradykinin, that are released by the inflamed tissues. Pain also helps to alert the client of the injury or infection and to limit the movement or use of the affected area.

Choice A reason: This is not the correct answer because opioids are a class of medications that act on the opioid receptors in the brain and spinal cord to reduce pain perception and emotional response. Opioids do not have a direct effect on tissue inflammation or bone healing, but they can cause side effects such as constipation, nausea, sedation, respiratory depression, and addiction.

Choice B reason: This is not the correct answer because anticoagulants are a class of medications that prevent or reduce the formation of blood clots by interfering with the clotting factors or platelets. Anticoagulants do not have a direct effect on tissue inflammation or bone healing, but they can increase the risk of bleeding and hematoma formation, which can impair the blood supply and oxygen delivery to the injured tissues.

Choice C reason: This is the correct answer because NSAIDs are a class of medications that inhibit the enzyme cyclooxygenase (COX), which is involved in the synthesis of prostaglandins, which are inflammatory mediators that cause pain, swelling, and fever. NSAIDs can decrease tissue inflammation and pain, but they can also delay bone healing by reducing the formation of osteoblasts, which are cells that build new bone tissue.

Choice D reason: This is not the correct answer because narcotics are another term for opioids, which are a class of medications that act on the opioid receptors in the brain and spinal cord to reduce pain perception and emotional response. Narcotics do not have a direct effect on tissue inflammation or bone healing, but they can cause side effects such as constipation, nausea, sedation, respiratory depression, and addiction.
