Correct Answer: B

Rationale: Pharmacodynamics refers to the drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions. It involves understanding how drugs interact with the body at the molecular level to produce their effects, including mechanisms of action, receptor binding, and downstream physiological responses. Choice A is incorrect because it describes pharmacopeia, which is a reference book containing standards for drugs. Choice C refers to efficacy, which is the maximum effect a drug can produce. Choice D describes pharmacokinetics, which focuses on the movement of drugs within the body.

Correct Answer: A

Rationale: Maintaining skill competency is a critical aspect of legal practice guidelines for healthcare professionals. It is essential to ensure that healthcare professionals are competent and up-to-date with their skills to provide safe and effective care to patients. While determining the dosage, monitoring for adverse effects, and safeguarding medications are important aspects of medication administration, maintaining skill competency is a fundamental legal responsibility that ensures the delivery of quality care. Determining the dosage and monitoring for adverse effects are clinical responsibilities, while safeguarding medications pertains to proper storage and handling, not specifically related to legal practice guidelines.

Correct Answer: D

Rationale: The correct nursing interventions to perform when a patient is on Albuterol include assessing the patient's lung sounds, pulse, and blood pressure before administering the medication to monitor for cardiovascular side effects like increased heart rate. Additionally, it is crucial to observe for paradoxical bronchospasms, a rare but serious adverse reaction where the medication causes a worsening of bronchospasm instead of relief. Monitoring for changes in behavior is not directly related to Albuterol administration and is not a standard nursing intervention for patients receiving this medication, making choice B incorrect. Therefore, the correct answer is D as it includes the essential nursing actions for patients on Albuterol.

Correct Answer: A

Rationale: The correct instruction for the nurse to include in the discharge teaching for a client prescribed Warfarin is to 'Avoid foods high in vitamin K.' Foods high in vitamin K can decrease the effectiveness of Warfarin by interfering with its anticoagulant effects, potentially leading to blood clotting issues. It is crucial for clients on Warfarin therapy to maintain a consistent intake of vitamin K-containing foods to ensure the stability of the medication's effects. Choices B, C, and D are incorrect because taking Warfarin with food, monitoring heart rate daily, or limiting fluid intake are not directly related to optimizing the effectiveness of Warfarin therapy.

Correct Answer: A

Rationale: The correct instruction that the nurse should include for a client prescribed Sucralfate is to take the medication on an empty stomach. Sucralfate works by forming a protective barrier over ulcers, which is most effective when the stomach is empty. Taking it with food or other medications may decrease its effectiveness. Instructing the client to take Sucralfate on an empty stomach helps ensure optimal therapeutic benefits. Choices B, C, and D are incorrect because increasing high-sodium foods is not related to Sucralfate therapy, taking the medication with a full glass of milk is not recommended as it may decrease its effectiveness, and the presence of black and tarry stools is not an expected outcome of Sucralfate.
