When a person touches a hot stove, the resulting cellular damage causes a reaction that converts the stimuli into a pain impulse. What is the term for this conversion?
Perception
Transduction
Modulation
Transmission
The Correct Answer is B
A. Perception. Perception occurs when the brain processes and interprets the pain signal, which happens after the stimulus has been converted and transmitted.
B. Transduction. Transduction is the process where a painful stimulus, such as touching a hot stove, causes cellular damage, leading to the release of chemical mediators that convert the stimulus into a pain impulse.
C. Modulation. Modulation involves the body's response to pain, including the release of endorphins to inhibit pain signals and reduce pain sensation.
D. Transmission. Transmission refers to the movement of the pain impulse from the site of injury to the spinal cord and brain, occurring after transduction has taken place.

Correct Answer is ["2"]
Explanation
Calculation:
Formula:
Capsulesperdose = Dose ordered/ Dose available
Given:
- Ordered dose = 2 mg
- Available dose = 1 mg per capsule
Capsulesperdose = 2mg/(1mg/capsule)
= 2 capsules
Thus, the nurse will administer 2 capsules per dose.
Correct Answer is A
Explanation
A. "The top number is the systolic blood pressure and reflects the pressure on the arteries when the heart contracts." The systolic pressure (118 mmHg) represents the force exerted on the arterial walls when the heart contracts and pumps blood.
B. "The numbers are within normal range and nothing to worry about." While 118/82 mmHg is within the normal range, this response does not explain what the numbers mean, which was the patient’s question.
C. "The concept of blood pressure is difficult to understand. The main thing to be concerned about is the top number, or systolic blood pressure." While the systolic pressure is important, the diastolic pressure is also crucial for assessing cardiovascular health. This response also discourages patient education.
D. "The bottom number is the diastolic pressure and reflects the stroke volume of the heart." Diastolic pressure (82 mmHg) represents the pressure in the arteries when the heart is at rest, not stroke volume, which refers to the amount of blood ejected per heartbeat.
