A 38-year-old man has come into the urgent care center with severe hip pain after falling from a ladder at work. He says he has taken several pain pills over the past few hours but cannot remember how many he has taken. He hands the nurse an empty bottle of acetaminophen (Tylenol). The nurse is aware that the most serious toxic effect of acute acetaminophen overdose is which condition?

Choice A reason: This statement is false. The patient’s radial pulse is 105 beats/min is not the assessment data that will require the most rapid response by the nurse. A high pulse rate can indicate dehydration, anxiety, or fever, but it is not a life-threatening condition.

Choice B reason: This statement is false. There is sediment and blood in the patient’s urine is not the assessment data that will require the most rapid response by the nurse. Sediment and blood in the urine can indicate kidney damage, infection, or trauma, but they are not an immediate complication of hyponatremia.

Choice C reason: This statement is true. There are crackles throughout both lung fields is the assessment data that will require the most rapid response by the nurse. Crackles are abnormal lung sounds that indicate fluid accumulation in the alveoli, which can impair gas exchange and cause respiratory distress. Crackles can be a sign of pulmonary edema, a serious complication of hyponatremia that requires prompt treatment.

Choice D reason: This statement is false. The blood pressure increases from 120/80 to 142/94 mm Hg is not the assessment data that will require the most rapid response by the nurse. A high blood pressure can indicate fluid overload, stress, or pain, but it is not a critical condition.

Choice A reason: This statement is true. Kayexalate is a medication that binds to potassium in the colon and exchanges it for sodium, thereby lowering the blood potassium level. It also has a laxative effect, which helps to eliminate the excess potassium in the stool.

Choice B reason: This statement is false. Kayexalate does not have a diuretic effect, which means it does not increase urine output or fluid loss. Diuretics are medications that act on the kidneys and help to remove excess fluid and sodium from the body.

Choice C reason: This statement is false. Kayexalate does not lower the blood sodium level, but rather increases it. This is because it exchanges potassium for sodium in the colon, which adds more sodium to the bloodstream.

Choice D reason: This statement is false. Kayexalate does not cause diarrhea, but rather a laxative effect, which means it stimulates bowel movements and softens the stool. Diarrhea is a condition where the stool is watery and frequent, and can cause dehydration and electrolyte imbalance.
