A 42-year-old woman presents with a 5-day history of progressive weakness in the right foot, as well as a loss of sensation in the foot. She states that she hit her knee. Physical exam findings are a bruise on the anterolateral aspect of the knee, numbness on the upper anterior part of the leg, and weakness of foot eversion. Superficial peroneal nerve
<h3>What is
Superficial peroneal nerve?</h3>
The greater portion of the dorsum of the foot, the fibularis longus, and the fibularis brevis muscles are all innervated by the superficial fibular nerve, which is also referred to as the superficial peroneal nerve (with the exception of the first web space, which is innervated by the deep fibular nerve). The major nerve in the lateral compartment of the leg is the superficial fibular nerve. The muscles of the fibularis longus and fibularis brevis are where it starts, on the side of the fibula neck. It falls between the fibularis longus and fibularis brevis in the middle part of the leg, then reaches the anterior border of the latter to enter the groove between the latter.

The correct option is (c) 70%.
The nurse would document 70% blood oxygen saturation as normal for the patient.
What is Venous oxygen saturation?
- The amount of oxygen in the blood that returns to the right side of the heart after perfusing the entire body is known as venous oxygen saturation (SvO2).
- An abnormal SvO2 results from insufficient systemic oxygenation when the oxygen supply is insufficient to meet the metabolic demands of the tissues.
- To assess the severity of tissue hypoperfusion situations and the mixed venous blood oxygen saturation levels, continuous central venous oximetry (ScvO2) monitoring may be performed.
- As blood returns to the heart and pulmonary system to be re-oxygenated, a central catheter is inserted into the superior vena cava (SVC), and a sensor on the catheter monitors the oxygen saturation of the blood in the SVC. 70% is the average ScvO2 value.

I understand that the question you are looking for is "The nurse is using continuous central venous oximetry (ScvO2) to monitor the blood oxygen saturation of a patient in shock. What value would the nurse document as normal for the patient?
(a)60%
(b)50%
(c)70%
(d)40%"
The correct answer for this question is Placing a thin pillow under the bony prominences.
An area of wounded skin is referred to as a pressure injury, bedsore, pressure ulcer, pressure sore, or decubitus ulcer. When pressure is applied to the skin's surface, a pressure injury occurs. This force may exert constant pressure on a patch of skin, or it may pull (shear) the skin away from another surface. These wounds typically occur across the body's bony regions (hips, heels, tailbone, elbows, head and ankles). A pressure injury can become life-threatening if it develops to a deep wound or becomes infected.
