Calculate the infusion time for an IV of 1,500 mL running at 25 gtt/min. if the drop factor is 15 gtt/mL.

A. "Continue taking OCPS because phenytoin is not safe during pregnancy."

This statement is not accurate. While it's essential to address pregnancy risk, phenytoin can reduce the effectiveness of oral contraceptives. Women on phenytoin are often advised to use additional contraceptive measures.

B. "You should use a backup method of contraception along with OCPs."

This is the correct response. Phenytoin can accelerate the metabolism of oral contraceptives, potentially reducing their effectiveness. Using a backup method, such as condoms, is recommended to ensure adequate contraception.

C. "You should stop taking OCPs because of drug-drug interactions with phenytoin."

This advice is generally not recommended without consulting the healthcare provider. Abruptly stopping OCPs without an alternative form of contraception can increase the risk of unintended pregnancy.

D. "You should take low-dose aspirin while taking these medications to reduce your risk of stroke."

This statement is not relevant to the situation described. Low-dose aspirin is not typically recommended for contraception, and its use in this context does not address the potential interaction between phenytoin and oral contraceptives.

A. Combination therapy has the best outcomes when omeprazole, propranolol, bismuth salicylate are used.

Propranolol is not an antibiotic and is not part of the standard combination therapy for H. pylori. Bismuth subsalicylate may be used in some regimens, but the standard involves a proton pump inhibitor, clarithromycin, and amoxicillin or metronidazole.

B. Combination therapy has the best outcomes when omeprazole, clarithromycin, and amoxicillin are used.

This is the correct choice. The standard combination therapy for H. pylori infection includes a proton pump inhibitor (such as omeprazole), clarithromycin, and amoxicillin or metronidazole.

C. The use of sucralfate along with antibiotics is the best combination therapy for peptic ulcer disease.

Sucralfate is not typically part of the standard antibiotic combination therapy for H. pylori. It is a cytoprotective agent that may be used to treat ulcers but is not a primary component in eradicating H. pylori.

D. Various antibiotics are used to eradicate the bacteria that are responsible for the development of peptic ulcer disease.

While this statement is true, it does not specify the standard combination therapy. The most common antibiotics used in combination therapy for H. pylori include clarithromycin and amoxicillin or metronidazole, along with a proton pump inhibitor.
