Which of the following medication administration routes has the most rapid onset of action?
Sublingual
Intradermal
Subcutaneous
Intravenous
The Correct Answer is D
Intravenous (IV) administration of medication involves injecting the medication directly into a vein. This route of administration has the most rapid onset of action because the medication is delivered directly into the bloodstream and can be quickly distributed throughout the body.
Options a, b, and c are not correct because they do not have as rapid an onset of action as intravenous administration. Sublingual administration involves placing the medication under the tongue, where it is absorbed into the bloodstream through the mucous membranes. Intradermal administration involves injecting the medication into the top layer of the skin. Subcutaneous administration involves injecting the medication into the fat tissue just under the skin. While these routes can be effective for delivering medication, they do not have as rapid an onset of action as intravenous administration.

Correct Answer is A
Explanation
The half-life of a medication is the time it takes for the concentration of the medication in the body to decrease by half. In this case, the medication has a half-life of 2 hours and a current toxic level of 40 mEq/dL. After 2 hours, the level will decrease to 20 mEq/dL. After another 2 hours (4 hours total), the level will decrease to 10 mEq/dL, which is within the normal range. However, it will take another 21 half-lives (42 hours) for the level to reach 5 mEq/dL, which is the lower end of the normal range. Therefore, it will take a total of 25 hours (4 + 21) for the medication to reach the normal range.
Option B is incorrect because it would take much longer than 24 hours for the medication to reach the normal range.
Option C is incorrect because it would only take 2 hours for the medication to decrease by half, not reach the normal range.
Option D is incorrect because it would take longer than 4 hours for the medication to reach the normal range.
Correct Answer is ["A","D"]
Explanation
A. Tolerance can develop over time and lead to the need for higher doses – This is correct because long-term use of clonazepam, like other benzodiazepines, can result in tolerance, potentially necessitating higher doses to achieve the same therapeutic effect.
B. Skip a dose if you need to drive – This is incorrect. Clients should be advised to take their medication as prescribed and consult their healthcare provider about driving, as clonazepam can impair coordination and reaction times.
C. Skip a dose if you plan to go out drinking with friends – This is incorrect. While it’s important to avoid alcohol when taking clonazepam due to the increased risk of sedation and respiratory depression, clients should not skip doses without consulting their healthcare provider.
D. Do not try to taper yourself off this medication without physician guidance – This is correct. Stopping clonazepam suddenly can lead to withdrawal symptoms and seizure recurrence, so any changes in medication should always be done under the guidance of a healthcare provider.
