E, F, G: No information provided.
Question 3 of 5
A client is admitted to a hospital for treatment for first-time acute symptoms of mania. The nurse anticipates the provider will prescribe which of the following medications?
Correct Answer: A
Rationale: The correct answer is A: Lithium [Lithobid]. Lithium is a first-line treatment for acute mania due to its mood-stabilizing properties. It helps regulate neurotransmitter levels in the brain, particularly dopamine. It has a quick onset of action and is effective in managing manic symptoms. Diazepam (
B) is a benzodiazepine used for anxiety, not mania. Bupropion (
C) is an antidepressant and not typically used for mania. Paroxetine (
D) is an SSRI used for depression and anxiety, not mania. In summary, lithium is the correct choice due to its specific mood-stabilizing effects tailored for manic symptoms, while the other options are not appropriate for treating acute mania.
Question 4 of 5
The nurse is preparing to administer digoxin (Lanoxin) 750 mcg PO daily. Available: See label below. How many pills should the nurse administer? Do not round your answer. Enter numeric answer only.
Correct Answer: A
Rationale: The label indicates that each pill contains 250 mcg of digoxin.
To calculate how many pills the nurse should administer for a total of 750 mcg daily, divide the total dose by the dose per pill: 750 mcg ÷ 250 mcg/pill = 3 pills.
Therefore, the correct answer is A.
Choice B and other options are incorrect because they do not align with the calculated dosage based on the label information.
