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 helps increase the oxygen-carrying capacity of the blood and corrects anemia.
Choice B is wrong because erythropoietin is not given to all people with anemia. It is only used for certain types of anemia, such as those caused by chronic kidney disease or chemotherapy.
Choice C is wrong because erythropoietin is not given for iron deficiency anemia. Iron deficiency anemia is treated with iron supplements and dietary changes.
Choice D is wrong because erythropoietin does not stimulate bone marrow production of white blood cells. White blood cells are involved in immune responses and are produced by different growth factors.
Question 22.
Correct Answer is C
Explanation
This nursing diagnosis is typically not associated with anemia because anemia does not cause dehydration or loss of body fluids. Anemia is a condition in which the hemoglobin concentration or the number of red blood cells is lower than normal, resulting in decreased oxygen delivery to the tissues.
Choice A. Ineffective tissue perfusion is wrong because anemia can impair tissue perfusion by reducing the oxygen-carrying capacity of the blood.
Choice B. Activity intolerance is wrong because anemia can cause fatigue, weakness, and dyspnea on exertion due to inadequate oxygen supply to the muscles.
Choice D. Risk for decreased cardiac output is wrong because anemia can increase the risk of cardiac complications such as tachycardia, palpitations, angina, and heart failure due to increased cardiac workload and demand for oxygen.
Normal ranges for hemoglobin are 13.5 to 17.5 g/dL for men and 12 to 15.5 g/dL for women; normal ranges for hematocrit are 38.8 to 50% for men and 34.9 to 44.5% for women; normal ranges for red blood cell count are 4.7 to 6.1 million/mm3 for men and 4.2 to 5.4 million/mm3 for women; normal ranges for reticulocyte count are 0.5 to 1.5% of red blood cells.
