What drug would the nurse administer to treat a patient diagnosed with bronchospasm associated with chronic obstructive pulmonary disease (COPD)?

Choice A rationale

The half-life of a drug refers to the time it takes for the plasma concentration of a drug to reduce by half. It is not a primary consideration when substituting generic drugs for brand-name drugs.

Choice B rationale

Critical concentration is the amount of a drug needed to achieve therapeutic effects. While important, it is not the main factor in generic substitution.

Choice C rationale

Distribution describes how a drug is dispersed throughout the body's tissues and fluids. This factor is crucial for drug efficacy but not directly related to substituting generic drugs.

Choice D rationale

Bioavailability is the degree and rate at which an active drug ingredient is absorbed and becomes available at the site of action. Generic drugs must have the same bioavailability as brand-name drugs to ensure they are just as effective.

Choice A rationale

Maintaining narcan (naloxone) on standby is not directly related to anticoagulant therapy. Narcan is used to reverse opioid overdoses, not to manage the effects of anticoagulants.

Choice B rationale

Notifying the healthcare provider of any patient receiving this drug is a general action but not an appropriate nursing diagnosis. Nursing diagnoses focus on identifying specific patient needs and planning care to address those needs.

Choice C rationale

Evaluating the patient for PT (prothrombin time) for 2.5 is an action, not a nursing diagnosis. Nursing diagnoses identify patient needs and risks, guiding the planning and implementation of care.

Choice D rationale

Establishing safety precautions is an appropriate nursing diagnosis for a patient on anticoagulant therapy. Anticoagulants increase the risk of bleeding, so ensuring patient safety and preventing injury is crucial to minimize this risk. .
