Correct Answer: C

Rationale: Flumazenil is a specific benzodiazepine antagonist that competitively reverses the sedative effects of benzodiazepines like Diazepam. In cases of oversedation or respiratory depression caused by benzodiazepines, administering Flumazenil can help reverse the effects and restore the client's consciousness and respiratory drive.

Correct Answer: D

Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This is important for proper absorption of the medication. Additionally, rotating the patch to different sites each day helps prevent skin irritation and ensures optimal therapeutic effect. Applying the patch to the same site each day can lead to skin irritation or tolerance development. Removing the patch at night is not necessary as the patch is typically worn continuously to provide a consistent level of medication. Covering the patch with a heating pad is contraindicated as it can increase drug absorption, potentially leading to adverse effects.

Correct Answer: C

Rationale: Flumazenil is a competitive benzodiazepine antagonist that can reverse the sedative effects of benzodiazepines like Diazepam. In cases of oversedation, administering Flumazenil can help counteract the excessive sedation and other effects of Diazepam, thereby promoting the client's recovery and preventing potential complications.
