Question 1 of 5
Which of the following drugs most likely caused the patient's signs and symptoms?
Correct Answer: D
Rationale: The signs and symptoms described in the text, such as talkativeness, mydriasis, muscle twitching, hand tremor, elevated blood pressure, and increased heart rate, are consistent with the effects of amphetamine use. Amphetamine is a stimulant drug that can cause these symptoms by increasing the release of neurotransmitters like dopamine and norepinephrine in the brain. Additionally, the patient being a drug user who tried different drugs supports the likelihood of amphetamine use, as it is commonly abused for its stimulant effects.
Question 2 of 5
A patient is having absence seizures. Which of the following does the nurse expect to be prescribed for this type of seizure? (Select all that apply.)
Correct Answer: C
Rationale: The correct answer is C: Valproic acid. Valproic acid is commonly prescribed for absence seizures due to its effectiveness in controlling this specific type of seizure. It works by increasing the levels of the inhibitory neurotransmitter GABA in the brain, helping to prevent the abnormal electrical activity that leads to absence seizures. Phenytoin (A) and Phenobarbital (B) are not typically used for absence seizures. Phenytoin is more commonly used for focal and tonic-clonic seizures, while Phenobarbital is often used for generalized tonic-clonic seizures. Clonazepam (D) is also not the first-line treatment for absence seizures. It is more commonly used for myoclonic seizures and certain types of epilepsy syndromes.
