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.

Answer and Explanation

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 C

Explanation

This action is intended to prevent a sentinel event, which is a patient safety event that results in death, permanent harm, or severe temporary harm. A sentinel event is a serious adverse event that signals the need for immediate investigation and response. Removing the wrong arm would be a devastating and irreversible outcome for the patient and the health care provider.

Choice A is wrong because the lack of healing of the stump is not a sentinel event. It is a possible complication of amputation that may be related to the natural course of the patient’s illness or underlying condition.

Choice B is wrong because ineffective control of the client’s pain is not a sentinel event. It is a quality of care issue that may affect the patient’s comfort and recovery, but it does not result in death, permanent harm, or severe temporary harm.

Choice D is wrong because the client being mildly sedated is not a sentinel event. It is a level of anesthesia that may be appropriate for some types of surgery, but it does not result in death, permanent harm, or severe temporary harm.

A. Ineffective tissue perfusion. B. Activity intolerance. C. Fluid volume deficit. D. Risk for decreased cardiac output.

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.
