A patient requires a nonopioid medication. The nurse knows that which medication will cause the least gastrointestinal distress?

Correct Answer: C

Rationale: Celecoxib is a selective COX-2 inhibitor, which means it primarily targets the COX-2 enzyme involved in inflammation and pain while sparing the COX-1 enzyme that protects the stomach lining. This selectivity reduces the risk of gastrointestinal distress, such as ulcers and bleeding, compared to non-selective NSAIDs like aspirin, ketorolac, and ibuprofen. Therefore, celecoxib is the best choice for patients who require a nonopioid medication with minimal gastrointestinal side effects. Nurses should consider this when selecting pain management options for patients with a history of gastrointestinal issues.

Correct Answer: D

Rationale: The correct statement is that the heparin provides anticoagulation until therapeutic levels of warfarin are reached. Heparin and warfarin are both anticoagulants but work in different ways. Heparin acts quickly to prevent blood clot formation while warfarin takes several days to reach its full effect. Therefore, heparin is often used initially to provide immediate anticoagulation while waiting for the warfarin to reach therapeutic levels. This dual therapy is common in clinical practice to ensure continuous anticoagulation.

Correct Answer: A

Rationale: Metformin belongs to the class of medications known as biguanides. Biguanides work primarily by decreasing glucose production in the liver and increasing insulin sensitivity in peripheral tissues, such as muscles. They also help improve glucose uptake and utilization by cells, leading to better control of blood sugar levels. Metformin is commonly used to treat type 2 diabetes mellitus and can also be used in the management of polycystic ovary syndrome (PCOS).

Correct Answer: D

Rationale: A spirit is an alcoholic or hydroalcoholic solution of volatile substances obtained by distillation. It is commonly used in the production of alcoholic beverages and in the pharmaceutical industry for preparing tinctures and extracts. Spirits are characterized by their high alcohol content and ability to extract and preserve the properties of the substances they are derived from. Decoction is a method of extracting compounds from plants using boiling water, fluid extract is a concentrated liquid extract of a substance, solution refers to a homogeneous mixture of substances, and syrup is a thick, sweet liquid usually made by dissolving sugar in water.
