Answer and Explanation

Correct Answer : A,B,C,D,E

The correct answer is choices A, B, C, D, and E.

Hypoxia occurs when there is inadequate oxygen supply to the body's tissues. Signs of hypoxia can vary depending on the severity of the condition. The following signs can indicate hypoxia:

  • Increased respiratory rate - Hypoxia can cause an increased respiratory rate as the body tries to increase oxygen levels in the blood.
  • Confusion - Hypoxia can affect cognitive function, leading to confusion.
  • Cyanosis - Hypoxia can cause a blue or purple discoloration of the skin, lips, or nail beds due to the lack of oxygen.
  • Restlessness - Hypoxia can cause restlessness or agitation.
  • Dyspnea - Hypoxia can cause difficulty breathing, also known as dyspnea.

  • Bradycardia - Bradycardia, or a slow heart rate, is not typically a direct sign of hypoxia. Hypoxia often leads to tachycardia (increased heart rate) as the body tries to compensate for low oxygen levels.

  • Hypotension - While severe hypoxia can eventually lead to changes in blood pressure, hypotension (low blood pressure) is not a primary sign of hypoxia. Typically, hypoxia might cause hypertension or have no immediate impact on blood pressure.

  • Nausea and Vomiting - While nausea and vomiting can be related to various conditions, they are not specific signs of hypoxia. These symptoms might occur due to other issues or as a secondary effect in some cases, but they are not primary indicators of hypoxia.

Correct Answer is A

Explanation

The correct answer is choice A: "The JP drain uses negative suction to drain fluid from the wound." The purpose of the Jackson-Pratt drain is to remove excess fluid or blood from the surgical site. This drain uses a bulb-like container that creates negative pressure or suction, which allows the fluid to be removed from the wound into the container. It is important to maintain negative pressure to ensure that the drain is functioning properly. The nurse should also instruct the client on how to monitor the drainage and how often to empty the container, and to report any changes in the amount, color, or odor of the fluid to the healthcare provider.

Correct Answer is D

Explanation

The correct answer is choice D. The nurse would explain to the patient that SCDs work by filling with air and applying intermittent or sequential pressure to the legs to enhance blood flow and venous return. This can help prevent blood clots, such as DVT, from forming in the legs. SCDs are often used for patients who are immobile, such as those who have undergone surgery or who are hospitalized for a medical condition. The device is comfortable to wear and can be adjusted to fit the patient's size and shape. The nurse would also explain the importance of wearing the device as prescribed, and how to properly use and care for it. By using SCDs as directed, the patient can significantly reduce their risk of developing a potentially life-threatening blood clot.
