What is the physiological effect of moist heat on the treated area?
Numbing the area treated.
Drawing fluid to the site of application.
dilating the blood vessels
Constricting the blood vessels.
The Correct Answer is C
Choice A rationale
Numbing the area treated is not a primary physiological effect of moist heat. Moist heat therapy works by increasing the temperature of the skin and underlying tissues, which does not directly numb the area but can lead to an increased pain threshold.
Choice B rationale
Drawing fluid to the site of application is not a physiological effect of moist heat. While moist heat can increase local circulation, it does not specifically draw fluids to the application site³.
Choice C rationale
Dilating the blood vessels is a key physiological effect of moist heat. The increased temperature from the heat application causes vasodilation, which increases blood flow to the area, promoting healing and reducing muscle spasm⁴.
Choice D rationale
Constricting the blood vessels is not a physiological effect of moist heat. In fact, the opposite occurs; moist heat causes vasodilation, not vasoconstriction.

Correct Answer is D
Explanation
Choice A:
This position would not be ideal for right eye irrigation. Tilting the head towards the left eye could cause the irrigation solution to flow into the left eye, potentially causing discomfort or harm⁵.
Choice B:
While the supine position is correct, hyperextending the head is not necessary and could cause discomfort to the patient.
Choice C:
This position could cause discomfort to the patient and does not facilitate the flow of the irrigation solution away from the nose and mouth.
Choice D:
This is the correct position for right eye irrigation. The supine position with the head tilted toward the right eye allows the solution to flow away from the nose and mouth, preventing aspiration or discomfort.
Correct Answer is C
Explanation
Choice A rationale
Elastic adhesive tape is not the best option for a patient experiencing skin irritation from tape removal because it may cause further irritation when removed.
Choice B rationale
Karaya paste is primarily used as a skin barrier and adhesive for ostomy appliances, not for securing dressings, especially in cases of skin irritation.
Choice C rationale
Montgomery straps are designed for situations where frequent dressing changes are needed. They allow the dressing to be changed without removing the adhesive straps each time, minimizing skin irritation.
Choice D rationale
Paper tape is less irritating to the skin than elastic adhesive tape, but it still requires removal with each dressing change, which can irritate sensitive skin.
