What is the category status for the drug Omeprazole?

Correct Answer: B

Rationale: Omeprazole is classified as an anti-ulcer agent. It belongs to a class of medications known as proton pump inhibitors (PPIs) that work by reducing the amount of acid produced in the stomach. Omeprazole is commonly used to treat conditions such as gastroesophageal reflux disease (GERD), ulcers, and Zollinger-Ellison syndrome. It is not a laxative, anti-heartburn medication, or antianemic drug.

Correct Answer: B

Rationale: Diazepam, a benzodiazepine, has active metabolites (e.g., desmethyldiazepam) with longer half-lives, contributing to its effects, so that's false. Activated charcoal is effective in overdose by adsorbing diazepam, reducing absorption, a true statement and standard intervention. It undergoes minimal, not extensive, enterohepatic recirculation, making that false. It's a GABA agonist, enhancing chloride influx via benzodiazepine receptors, not an antagonist, so that's incorrect. It also inhibits spinal reflexes, aiding muscle relaxation. The overdose utility of charcoal highlights its role in emergency management, binding unabsorbed drug in the gut, a key pharmacokinetic intervention distinct from flumazenil reversal.

Correct Answer: D

Rationale: Medication orders must be clear, complete, and appropriate for the patient's condition. Orders that include 'as needed' (PRN) medications, such as 'Docusate (Colace) as needed for constipation,' require clarification because they lack specific dosing instructions. The nurse must confirm the frequency, dosage, and indications for PRN medications to ensure safe administration. The other orders (Metformin, Sitagliptin, Simvastatin, and Irbesartan) are complete and do not require clarification. Therefore, the nurse should focus on clarifying the PRN order to avoid errors in medication administration.

Correct Answer: B

Rationale: Warfarin is an anticoagulant medication that works by inhibiting the body's ability to use vitamin K to form clotting factors. In cases of excessive anticoagulation or bleeding due to Warfarin, the antidote is vitamin K. Vitamin K helps the body produce clotting factors, thereby reversing the effects of Warfarin and promoting the blood to clot normally. Other medications like Narcan, Glucagon, and Vitamin B do not have a direct antidote effect for Warfarin toxicity.

Correct Answer: B

Rationale: Keratolytic drugs, such as salicylic acid, work by softening and removing the horny layer of the epidermis, which consists of dead skin cells. This helps treat conditions like psoriasis, warts, and calluses. They do not target the dermis (A), erythematous lesions (C), or hair follicles (D).
