Pharmacology is a critical area of study in NR 200 at Chamberlain College of Nursing, focusing on the safe and effective use of medications in patient care. This section of the course provides students with a comprehensive understanding of how drugs work, their therapeutic effects, and the potential side effects and interactions that can occur. Mastery of this content is essential for ensuring patient safety and optimizing treatment outcomes.
In NR 200, students delve into the principles of pharmacokinetics and pharmacodynamics, which explain how drugs are absorbed, distributed, metabolized, and excreted by the body. Understanding these principles is crucial for administering medications correctly and monitoring their effects on patients. For example, students learn about the metabolism of drugs like warfarin, an anticoagulant, and how its effects can be influenced by factors such as diet, liver function, and interactions with other medications. This knowledge enables nurses to adjust dosages and provide personalized care that minimizes the risk of adverse effects.
The course also covers a wide range of drug classes, including antibiotics, antihypertensives, analgesics, and sedatives. For each class, students learn about the indications for use, mechanisms of action, and potential side effects. For instance, in the case of antibiotics, students study the importance of completing the full course of treatment to prevent the development of antibiotic-resistant bacteria. They also learn about the common side effects of antibiotics, such as gastrointestinal upset, and how to manage these in patients.
Parenteral therapies, including intravenous (IV) medications and fluids, are another important focus of NR 200. Students are trained in the proper techniques for administering IV therapies, calculating infusion rates, and monitoring for complications such as infiltration or phlebitis. For example, when administering IV fluids to a dehydrated patient, students learn to assess the patient’s fluid status, choose the appropriate type and amount of fluid, and monitor the patient’s response to ensure effective rehydration.
A key component of pharmacological education in NR 200 is the prevention of medication errors. The course emphasizes the importance of adhering to the “five rights” of medication administration—right patient, right drug, right dose, right route, and right time. Students are taught to double-check all medications before administration and to be vigilant in monitoring patients for any adverse reactions. For instance, when administering insulin to a diabetic patient, students learn to verify the dosage and type of insulin, monitor blood glucose levels, and watch for signs of hypoglycemia.
Overall, the pharmacological and parenteral therapies component of NR 200 equips nursing students with the knowledge and skills needed to administer medications safely and effectively. This section of the course is essential for ensuring that students are prepared to provide high-quality, evidence-based care in their future nursing careers.
