Physical examination
Psychosocial assessment
Environmental assessment

Once the assessment is complete, the nurse develops a care plan that Artikels the patient’s needs, goals, and interventions. There are various types of care plans, including:

Problem-oriented care plans
Goal-oriented care plans
Nursing care plans

Common nursing diagnoses for medical-surgical patients include:

Acute pain
Impaired mobility
Risk for infection

Corresponding nursing interventions for these diagnoses may include:

Administering pain medication
Assisting with ambulation
Implementing infection control measures

Pharmacology

Pharmacology is the study of drugs and their effects on living organisms. It encompasses the discovery, development, mechanism of action, absorption, distribution, metabolism, excretion, and adverse effects of drugs.

In medical-surgical nursing, pharmacology plays a crucial role in the safe and effective administration of medications to patients. Nurses must have a thorough understanding of pharmacology to ensure that medications are used appropriately and to minimize potential adverse effects.

Routes of Medication Administration

Medications can be administered through various routes, each with its advantages and disadvantages. The choice of route depends on factors such as the drug’s properties, the patient’s condition, and the desired onset of action.

Oral:Convenient and cost-effective; suitable for drugs that are absorbed well from the gastrointestinal tract. Disadvantages include potential for nausea, vomiting, and delayed absorption.
Intravenous (IV):Rapid onset of action; suitable for drugs that need to be delivered quickly or in high concentrations. Disadvantages include risk of infection, thrombosis, and extravasation.
Intramuscular (IM):Moderate onset of action; suitable for drugs that are not well absorbed orally or need to be administered in a depot form. Disadvantages include pain and tissue irritation.
Subcutaneous (SC):Slow onset of action; suitable for drugs that are absorbed slowly or need to be administered over a prolonged period. Disadvantages include risk of infection and tissue irritation.
Transdermal:Slow onset of action; suitable for drugs that need to be delivered over a prolonged period or for local effects. Disadvantages include potential for skin irritation and allergic reactions.
