wer: C
anation: Preventing pressure ulcers is an important consideration whe ioning a patient for surgery under anesthesia. Prolonged pressure on in areas of the body, especially bony prominences, can lead to skin kdown and the development of pressure ulcers. Positioning devices, ing, and regular repositioning are used to minimize the risk of pressur
ulcers during surgical procedures.

Explanation: One advantage of using a laryngeal mask airway (LMA) during anesthesia is that it reduces the risk of aspiration of gastric contents. The LMA is a supraglottic airway device that sits above the vocal cords and forms a seal around the laryngeal inlet. This helps to prevent regurgitation and aspiration of stomach contents into the lungs during anesthesia.

Answer: A
Explanation: Hypoventilation is a potential complication of inhalation anesthesia. Inhalation anesthetics depress the central respiratory drive, which can lead to inadequate ventilation and a decrease in oxygen levels in the blood.
Close monitoring of the patient's respiratory status is essential during inhalation anesthesia to prevent hypoventilation and hypoxemia.

Answer: A
Explanation: Hypotension is a potential complication of epidural anesthesia.
Epidural anesthesia can cause a blockade of sympathetic nerve fibers, leading to vasodilation and a decrease in blood pressure. Close monitoring of blood pressure and appropriate fluid management are important during epidural anesthesia to prevent and manage hypotension.

Explanation: Hematoma formation is a potential complication of peripheral nerve blocks. Peripheral nerve blocks involve the injection of local anesthetic near a peripheral nerve to provide regional anesthesia. Hematomas can occur if blood vessels are inadvertently punctured during the procedure, leading to bleeding and the accumulation of blood in the surrounding tissues.
