A nurse is assessing a client after administering phenytoin IV bolus for a seizure. Which of the following findings should the nurse identify as an adverse effect of this medication?
Bradycardia.
Red man syndrome.
Hypotension.
Hypoglycemia.
The Correct Answer is C
Phenytoin is an anticonvulsant medication that can cause hypotension as an adverse effect when administered intravenously. The nurse should monitor the client’s blood pressure and heart rate during and after the infusion.
Choice A is wrong because phenytoin does not cause bradycardia. Bradycardia is a slow heart rate that can result from beta blockers, calcium channel blockers, or digoxin toxicity.
Choice B is wrong because red man syndrome is an adverse reaction to vancomycin, not phenytoin.
Red man syndrome is characterized by flushing, itching, and rash on the face, neck, and upper torso.
Choice D is wrong because phenytoin does not cause hypoglycemia. Hypoglycemia is a low blood glucose level that can result from insulin overdose, excessive exercise, or inadequate food intake.
Normal ranges for blood pressure are 90/60 mm Hg to 120/80 mm Hg. Normal ranges for heart rate are 60 to 100 beats per minute. Normal ranges for blood glucose are 70 to 110 mg/dL.

Correct Answer is D
Explanation
Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease1 and should be used with caution in patients with hepatic impairment or active liver disease. Alcohol use disorder can cause liver damage and increase the risk of acetaminophen toxicity.
Choice A is wrong because hepatitis B vaccine within the last week is not a contraindication for receiving acetaminophen.
There is no evidence that acetaminophen interferes with the immune response to the vaccine or causes adverse effects.
Choice B is wrong because chronic kidney disease is not a contraindication for receiving acetaminophen.
Acetaminophen is mainly metabolized by the liver and has minimal renal excretion.
However, patients with chronic kidney disease should consult their doctor before taking acetaminophen as they may have other conditions that affect its use.
Choice C is wrong because diabetes mellitus is not a contraindication for receiving acetaminophen.
Acetaminophen does not affect blood glucose levels or interact with oral antidiabetic drugs.
However, patients with diabetes mellitus should consult their doctor before taking acetaminophen as they may have other conditions that affect its use.
Correct Answer is A
Explanation
Hyponatremia is a condition where the sodium level in the blood is too low, which can cause confusion, lethargy, seizures, and coma. A hypertonic solution is a fluid that has a higher concentration of solutes than the blood, which can help raise the sodium level and reduce the brain swelling caused by hyponatremia. Therefore, improved cognition indicates that the treatment is effective.
Choice B. Cardiac arrhythmias absent.
Cardiac arrhythmias are not a common symptom of hyponatremia unless it is severe or rapid in onset.
Therefore, their absence does not necessarily indicate that the treatment is effective.
Choice C. Decreased vomiting.
Vomiting can be a cause or a consequence of hyponatremia, depending on the underlying condition.
Decreased vomiting may indicate that the patient is less nauseated, but it does not reflect the sodium level or the brain status.
Choice D. Absent Chvostek’s sign.
Chvostek’s sign is a facial twitching that occurs when tapping on the cheek, which indicates hypocalcemia (low calcium level).
It is not related to hyponatremia or hypertonic solution.
Normal ranges for sodium are 135 to 145 mEq/L and for calcium are 8.5 to 10.5 mg/dL.
