Final answer:
High Fowler's position involves seating a patient upright at a 90-degree angle, which is useful for various medical needs such as improved breathing or swallowing.
Step-by-step explanation:
If you are asked to place a patient in High Fowler's position, you would position the patient sitting upright or at a 90-degree angle. This position is commonly used to promote lung expansion for patients who have difficulty breathing, during feeding for those who have difficulty swallowing, or to reduce the risk of aspiration. Options b and c mentioned do not describe the High Fowler's position as they illustrate other body positions. Instead, High Fowler's position involves the patient being seated with the back of their bed raised so that the patient's torso is upright.
