Correct Answer: C

Rationale: Regular insulin, also known as short-acting insulin, typically exhibits a peak effect around 1 to 5 hours following administration. This rapid onset and peak effect make it suitable for managing postprandial glucose levels. In contrast, Insulin glargine is a long-acting insulin with no pronounced peak effect, NPH insulin has an intermediate duration of action, and Insulin lispro is a rapid-acting insulin that peaks within 30 minutes to 2.5 hours after administration.

Correct Answer: A

Rationale: The correct answer is Acetylcysteine. Acetylcysteine is the antidote for acetaminophen overdose. It works by replenishing glutathione, which is depleted in cases of acetaminophen overdose, thus preventing liver damage. Pegfilgrastim is a medication used to stimulate white blood cell production, misoprostol is a medication used to prevent gastric ulcers, and naltrexone is used in the management of opioid addiction and alcohol dependence, which are not indicated in the scenario described.

Correct Answer: B

Rationale: In a situation where Anginal pain persists after taking one sublingual tablet and waiting 5 minutes, it is crucial to call emergency services (911) immediately. This could indicate a myocardial infarction (heart attack) rather than a typical Anginal attack. The client can take a second sublingual tablet while waiting for emergency assistance. If the pain persists after taking the second tablet, a third tablet can be taken after an additional 5 minutes. Prompt action is essential in such situations to ensure appropriate and timely medical intervention.

Correct Answer: B

Rationale: The correct answer is to instruct the client to remain upright for 30 minutes after taking Alendronate. Alendronate can cause esophageal irritation and even ulceration if it remains in contact with the esophagus. By staying upright, the medication is more likely to pass through the esophagus and into the stomach, reducing the risk of irritation and complications.

Correct Answer: D

Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma, as it can worsen the condition. Glaucoma is a condition characterized by increased intraocular pressure, and using Oxybutynin can further elevate this pressure, potentially leading to serious complications such as vision impairment or damage to the optic nerve.
