The nurse is preparing to apply a transdermal analgesic patch to a patient. In what order should the nurse administer this medication?

Choice 1. Choose a new site and cleanse and dry an upper torso location.
Choice 2. Clip chest hair and open the medication package.
Choice 3. Keep the patch intact for 72 hours.
Choice 4. Place the patch, making sure all edges are in contact with the skin.

Question 2

The nurse is explaining the pain response process to a patient experiencing chronic pain. In which order should the nurse identify the steps in the neural pain pathway?

Choice 1. In the thalamus and cerebral cortex, the pain impulse becomes pain when the sensation reaches conscious levels and is perceived and evaluated by the person experiencing the sensation.
Choice 2. Dorsal horn synapses relay impulses up the spinal cord. Spinal neurons transmit the impulses via axons that cross over to the spinothalamic tract.
Choice 3. The impulses ascend the spinothalamic tracts and pass through the medulla and midbrain to the thalamus.
Choice 4. A noxious stimulus is perceived by cutaneous nociceptors and then transmitted through A-delta (A) and even smaller C nerve fibers to the spinal cord dorsal horn.

Answer to Question 1

Correct Answer: 1, 2, 4, 3
A transdermal patch is applied to a clean, dry area on the upper torso. If hair is present, it should be clipped before applying the patch. Apply the patch immediately after opening the package, ensuring complete contact with the skin, especially around the edges. The patch is effective for about 72 hours.

Answer to Question 2

Correct Answer: 4,2,3,1
The neural pain pathway physiology follows this order: A noxious stimulus is perceived by cutaneous nociceptors and then transmitted through A-delta (A) and even smaller C nerve fibers to the spinal cord dorsal horn. Dorsal horn synapses relay impulses up the spinal cord. Spinal neurons transmit the impulses via axons that cross over to the spinothalamic tract. The impulses ascend the spinothalamic tracts and pass through the medulla and midbrain to the thalamus. In the thalamus and cerebral cortex, the pain impulse becomes pain when the sensation reaches conscious levels and is perceived and evaluated by the person experiencing the sensation.
