During surgery, the nurse makes the following observations about the patient:

  • Pulse rises from 68 beats per minute to 110 beats per minute.
  • Temperature increases from 36.5 C to 38.50
  • Muscles appear rigid.

The circulating nurse anticipates preparation of:

A.

Naloxone (Narcan)

B.

Dantrolene (Dentrum)

C.

Furosemide (Lasix)

D.

Flumazenil (Romazicon)

E.

Flumazenil (Romazicon)

Answer and Explanation

The Correct Answer is B

The given observations suggest the occurrence of malignant hyperthermia (MH), a potentially life-threatening reaction to certain medications used during anesthesia. MH is characterized by an increase in heart rate (tachycardia), elevated body temperature (hyperthermia), and muscle rigidity. The primary treatment for MH is the administration of dantrolene, which is a skeletal muscle relaxant that helps to counteract the effects of the reaction.

Naloxone (Narcan) is an opioid receptor antagonist used to reverse the effects of opioid overdose or excessive opioid sedation.

Furosemide (Lasix) is a diuretic used to treat conditions such as edema and high blood pressure.

Flumazenil (Romazicon) is a benzodiazepine receptor antagonist used to reverse the effects of benzodiazepine overdose or excessive sedation.

Correct Answer is ["1.4"]

Explanation

We know that 7,000 units is equivalent to 5,000 units per ml. So, we can set up the proportion:

7,000 units / 5,000 units per ml = x ml / 1 ml x = 7,000 / 5,000

x = 1.4

Therefore, the nurse should administer 1.4 milliliters (ml) of heparin.

Correct Answer is ["C","D","E"]

Explanation

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.
