Which drug is the antidote of Alprazolam?

Correct Answer: C

Rationale: Flumazenil is the specific antidote for Alprazolam, which is a benzodiazepine sedative-hypnotic drug. Flumazenil works by competitively inhibiting the actions of benzodiazepines at the benzodiazepine receptor site on the gamma-aminobutyric acid (GABA) receptor complex. It effectively reverses the sedative effects of benzodiazepines like Alprazolam, making it the appropriate antidote in cases of benzodiazepine overdose or toxicity. The other options provided (Physostigmine, Protamine sulfate, and Acetylcysteine) are unrelated to Alprazolam and are not indicated as antidotes for this specific drug.

Correct Answer: A

Rationale: Amiodarone, labetalol, and carvedilol are not indicated for pediatric use and do not have established pediatric dosages. Phentolamine and prazosin have established pediatric dosages and would not need to be questioned. The nurse should always verify the appropriateness of medications for pediatric patients, as their pharmacokinetics and pharmacodynamics differ from adults.

Correct Answer: D

Rationale: Lithium is commonly used to treat bipolar disorder, where it is effective in reducing the frequency and severity of acute manic episodes. By stabilizing mood, lithium helps in preventing or decreasing the occurrence of manic episodes, which are characterized by elevated, irritable moods, increased energy, and impulsivity. However, it is important to note that lithium does not typically have direct effects on reducing the risk of myocardial infarction, GI ulcers, or respiratory distress.

Correct Answer: B

Rationale: A. Stroke is not typically associated with an adverse reaction to Montelukast. The most common adverse reactions include neuropsychiatric events such as mood changes, suicidal thoughts/behaviors, and allergic reactions affecting the skin and mucous membranes.

Correct Answer: D

Rationale: Pregnancy category A indicates that adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus. Therefore, the nurse can reassure the patient that the medication is safe to take as directed. The other options either overstate the risk or provide incomplete information. It is important for the nurse to provide accurate and evidence-based guidance to ensure the safety of both the patient and the fetus.
