When a person cuts a finger, nerve impulses travel to the spinal cord along afferent peripheral nerve fibers. What is this process?

Perception

Transduction

Modulation

Transmission

Answer and Explanation

The Correct Answer is D

A. Perception occurs when the brain interprets pain signals and recognizes them as pain. This step happens after the nerve impulses have been transmitted to the brain.
B. Transduction is the first step in the pain process, where painful stimuli (such as cutting a finger) activate nociceptors, converting the stimulus into an electrical signal.
C. Modulation involves the body’s response to pain signals, where descending nerve pathways release substances like endorphins to inhibit pain transmission. This occurs later in the pain process.
D. Transmission is the process of pain signals traveling from the site of injury to the spinal cord and brain via afferent nerve fibers. This step occurs after transduction and allows pain signals to reach the central nervous system.

Thus, 2 tsp = 10 mL.

A. Always take the patient's blood pressure manually using a sphygmomanometer. B. Monitor the patient's neurological status carefully for symptoms of a stroke. C. Assist the patient to sit and stand slowly when getting out of bed. D. Check the patient's blood pressure on a lower extremity using a thigh-sized cuff.

Correct Answer is C

Explanation

A. Always take the patient's blood pressure manually using a sphygmomanometer. While manual BP measurements can be more accurate, they are not the priority intervention for orthostatic hypotension, which primarily involves position changes and fall prevention.
B. Monitor the patient's neurological status carefully for symptoms of a stroke. Orthostatic hypotension can cause dizziness or fainting, but it is not a direct cause of stroke. Neurological assessment is important if symptoms arise but is not the primary intervention.
C. Assist the patient to sit and stand slowly when getting out of bed. Orthostatic hypotension causes a sudden drop in blood pressure upon standing, increasing the risk of falls and syncope. The priority action is to help the patient transition slowly from lying to sitting and standing to allow the body to adjust.
D. Check the patient's blood pressure on a lower extremity using a thigh-sized cuff. Lower extremity BP measurements are not standard for managing orthostatic hypotension. Blood pressure should be checked in both lying, sitting, and standing positions to monitor for significant drops.
