Prevent blood clots
Prevent malignant hyperthermia.
Promote fracture healing.
Reduce pain
Prevent fat embolism
Correct Answer : C,D,E
The nurse explains that immobilizing a fracture will:
- Help align the bone fragments and reduce movement, which is crucial for proper healing. Immobilization can help maintain the stability of the fracture site, allowing the bones to knit together and heal.
- Help to minimize movement and subsequent pain. It provides support and reduces stress on the injured area, which can help alleviate discomfort and promote a more comfortable healing process.
- Help to minimize movement and reduce the risk of fat globules from bone marrow entering the bloodstream and causing a fat embolism, a potentially serious complication.
Preventing blood clots, preventing malignant hyperthermia, and immobilizing a fracture are not directly related. Preventing blood clots typically involves other measures such as early mobilization, elevation, and medication to prevent deep vein thrombosis. Malignant hyperthermia is a rare, potentially life-threatening reaction to certain medications used during anesthesia, and immobilization does not directly prevent it.

Correct Answer is B
Explanation
According to the given information, Aydan's insulin lispro (Humalog) dosage is 1 unit per 50 grams of carbohydrates eaten. As Aydan has just consumed 150 grams of carbs for lunch, we can calculate the insulin dose as follows:
Insulin dose = Carbohydrates eaten / Insulin-to-carbohydrate ratio Insulin dose = 150 grams / 50 grams/unit
Insulin dose = 3 units
Therefore, the nurse should prepare to administer 3 units of Aydan's prescribed rapid-acting insulin (Insulin lispro) to cover the carbohydrates he consumed for lunch. The long-acting insulin (Glargine) is typically given at bedtime to provide a basal insulin level and is not directly related to meal coverage.
Correct Answer is A
Explanation
Anaphylaxis is a severe and potentially life-threatening allergic reaction that can lead to a rapid drop in blood pressure, known as hypotension. This drop in blood pressure is a critical indicator of the severity of the reaction and the effectiveness of the treatment provided. The nurse needs to monitor the patient's blood pressure closely to ensure it stabilizes and returns to a safe range.
While oxygen saturation, heart rate, and orientation are also important parameters to assess, they are secondary to blood pressure in evaluating the effectiveness of treatment for anaphylaxis. Oxygen saturation can help determine the adequacy of oxygenation, heart rate can indicate the presence of tachycardia (which may be a sign of an ongoing reaction or hypoperfusion), and orientation can provide information about the patient's mental status and potential complications.
