A nurse working in the PACU (post-anesthesia care unit)/recovery room unit is monitoring a patient whose vital signs were stable upon arrival from the operating room. The patient’s temperature began to rise steadily the past 20 minutes and continues to rise, the heart monitor shows sinus tachycardia with a rate of 122, the patient’s blood pressure is 86/42, and pulse ox is 88% on 2 L O2 via nasal cannula.
The nurse suspects which genetic condition?
Alpha-1 antitrypsin deficiency.
Malignant hypothermia.
Thalassemia.
Malignant hyperthermia.
The Correct Answer is D
Malignant hyperthermia is a severe reaction to certain drugs used for anesthesia that can cause muscle rigidity, fever, and a fast heart rate. It can be fatal if not treated promptly with medication, oxygen, body cooling, and supportive care. The patient’s symptoms match those of malignant hyperthermia.
Choice A is wrong because alpha-1 antitrypsin deficiency is a genetic disorder that affects the lungs and liver, causing shortness of breath, wheezing, and jaundice.
It does not cause a rise in body temperature or muscle rigidity. Choice B is wrong because malignant hypothermia does not exist. It is a misspelling of malignant hyperthermia.
Choice C is wrong because thalassemia is a genetic disorder that affects the production of hemoglobin, causing anemia, fatigue, and bone deformities.
It does not cause a rise in body temperature or muscle rigidity.

Correct Answer is A
Explanation
This is because people with COPD are more likely to catch respiratory infections such as colds, flu and pneumonia, which can worsen their symptoms and cause further lung damage. An influenza vaccine can help prevent flu and reduce the risk of complications.
Choice B. A broad-spectrum antibiotic is wrong because antibiotics are only effective against bacterial infections, not viral ones. Antibiotics are usually prescribed for COPD exacerbations caused by bacterial infections, but not for prevention.
Choice C. A bronchodilator is wrong because bronchodilators are medications that relax the muscles around the airways and make breathing easier. They are used to treat the symptoms of COPD, but they do not prevent respiratory infections.
Choice D. A corticosteroid is wrong because corticosteroids are anti inflammatory drugs that reduce swelling and mucus production in the airways. They are also used to treat the symptoms of COPD, but they do not prevent respiratory infections. In fact, long-term use of corticosteroids may increase the risk of infections by suppressing the immune system.
