The patient reports flushing, itching, hives, anxiety, and throat and tongue swelling. The nurse finds that the patient has a rapid, irregular pulse. Which condition may the patient have as a result of taking the antibiotic? The patient has developed an allergic anaphylactic reaction to the antibiotics. Flushing, itching, hives, anxiety, and throat and tongue swelling are symptoms associated with an allergic anaphylactic reaction.

The nurse should notify the provider when hypokalemia and a prescription for digoxin occur together. Loss of potassium is of special concern for patients taking digoxin, a drug for heart failure. By lowering potassium levels, loop diuretics increase the risk of fatal dysrhythmias from digoxin. The nurse is caring for a patient who is taking a barbiturate. Which assessment finding requires immediate action by the nurse? A blood pressure of 80/50 mm Hg will require immediate treatment because it may be indicative of an overdose of the medication. Nitroglycerin therapy is ineffective in preventing angina in a patient, and so the patient is prescribed ranolazine. Which assessment finding in the patient will the nurse report to the primary health care provider? Ranolazine prolongs the QT interval on the electrocardiogram. It is used in patients who fail to benefit from other antianginal therapy. Ranolazine increases digoxin levels in patients, which may result in toxicity. Therefore, it is important to assess hepatic function in the patient so that the drug is excreted properly. The heart undergoes cardiac remodeling during the initial phase of heart failure. Which structural change occurs with heart failure? An increase in ventricular wall thickness, also called ventricular hypertrophy , is characteristic of the remodeling process during the initial phase of heart failure. The ventricles also dilate and become more spherical (less cylindric).
