Question 1 of 5
What is the expected outcome for Valproate?
Correct Answer: D
Rationale: Valproate is an anticonvulsant medication commonly used to treat seizures, epilepsy, and bipolar disorder. It works by increasing levels of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) in the brain and also affects other neurotransmitters. Therefore, the expected outcome of taking Valproate is to decrease seizure activity by stabilizing abnormal electrical activity in the brain.
Question 2 of 5
When reviewing the mechanisms of action of diuretics, the nurse knows that which statement is true about loop diuretics?
Correct Answer: D
Rationale: Loop diuretics, such as furosemide, act on the loop of Henle in the kidney to inhibit sodium and chloride reabsorption. This leads to a rapid diuretic effect by increasing the excretion of water along with sodium, chloride, and potassium. Loop diuretics have a quick onset of action, typically within 30 minutes of administration, and can cause a significant increase in urine output within a short period of time. This makes them ideal for treating conditions that require rapid elimination of excess fluid, such as acute pulmonary edema or severe hypertension.
