The document summarizes the key structures and functions of the integumentary system in 3 paragraphs or less:
The integumentary system includes the skin, hair, and nails. The skin is the largest organ and protects the body from damage, regulates temperature, and detects sensations. It is composed of three layers - the epidermis, dermis, and hypodermis. The epidermis contains keratinocytes and other cell types and becomes keratinized to form a protective barrier. Hair grows from follicles in the dermis and comes in different types. Glands in the skin including sweat glands help regulate temperature and sebaceous glands produce oil to moisturize the skin.
Based on the assessment findings provided, M.H. appears to have developed postoperative pneumonia and ileus.
The crackles heard on auscultation of her lungs along with a fever suggest she has a postoperative pulmonary infection like pneumonia.
Her abdominal tenderness, distension and absence of bowel sounds indicate she has developed an ileus, which is delayed return of normal bowel function and gas/stool movement after surgery. The brownish-green drainage from her NG tube is also consistent with ileus.

The document uses the example of a 45-year-old female with hypertension, diabetes and anxiety about her breast cancer surgery to demonstrate the presurgical assessment.
This document discusses how psychosocial, cultural, and genetic factors can influence pharmacotherapy outcomes. It notes that effective pharmacotherapy requires considering biological, psychological, social, cultural, and environmental variables that may impact drug response. Specific influences discussed include spiritual/religious beliefs, ethnicity, culture, literacy levels, and genetic polymorphisms. Gender differences are also outlined, such as varying responses, behaviors, and drug coverage based on sex. The holistic nursing approach of considering all these influences is emphasized for achieving successful pharmacotherapy.
The document discusses drug administration throughout the lifespan. It covers considerations for drug use during pregnancy, lactation, infancy, childhood, adolescence, and aging. Key factors that affect pharmacokinetics at different life stages are growth and development changes, organ system changes, and age-related changes in absorption, distribution, metabolism and excretion of drugs. The document emphasizes the importance of understanding life stage considerations and providing appropriate patient education for safe and effective pharmacotherapy.
This document discusses complementary and alternative medicine (CAM) therapies, focusing on herbal supplements. It defines CAM as treatments considered outside mainstream healthcare. Major CAM characteristics include treating each person as an individual and emphasizing mind-body connections. The document reviews various CAM healing methods, common herbal supplements, dietary supplement regulations, and the nurse's role in educating patients about CAM therapies and potential herb-drug interactions. It emphasizes the need for rigorous research on herbal supplement effectiveness and standardization.
This document discusses key concepts in pharmacodynamics including:
1) Pharmacodynamics examines how medicines change the body and helps predict drug effects.
2) Frequency distribution and dose-response curves illustrate variability in individual drug responses.
3) The median effective dose is the dose that produces a therapeutic response in 50% of patients.
4) Drugs can act as agonists, partial agonists, or antagonists at receptor sites to stimulate or inhibit responses.
1. Medication errors are common and can harm patients, increasing costs and negatively impacting facilities. They are caused by factors involving healthcare providers, patients, and systems.
2. It is important to accurately document and report all medication errors to determine root causes and implement strategies to prevent future errors. Reducing distractions, cross-checking orders, and reconciling medications can help reduce errors.
3. Educating patients on their medications also helps reduce errors by empowering them to participate in the medication administration process. Automated systems, electronic records, and updated policies further aim to minimize medication errors.
The document discusses the nursing process as it relates to pharmacology and medication administration. It describes the 5 steps of the nursing process - assessment, diagnosis, planning, implementation, and evaluation. Considerable detail is provided about properly assessing patients, identifying nursing diagnoses related to medication, setting goals and expected outcomes, implementing interventions like medication administration and monitoring, and evaluating the effectiveness of the care plan. The overarching goals of the nursing process in pharmacology are safe and effective medication administration and optimal patient wellness.
This document discusses the key principles of pharmacokinetics - how drugs move through the body. It describes the four main components of pharmacokinetics: absorption, distribution, metabolism, and excretion. Absorption involves a drug moving from its site of administration through membranes and into circulation. Distribution is the transport of drugs throughout tissues, influenced by factors like blood flow and binding to plasma proteins. Metabolism biochemically alters drugs in the liver to make them more easily excreted. Excretion primarily occurs through the kidneys which filter drugs out of the bloodstream. Understanding pharmacokinetics helps explain how the body handles medications and any obstacles they may face.
Drugs are organized in two ways: by therapeutic classification based on their clinical effects, and by pharmacologic classification based on their mechanism of action. Drugs have three names - a chemical name assigned by IUPAC, a generic name assigned by the USAN Council, and one or more trade or brand names assigned by the marketing company. Drugs considered to have abuse or addiction potential are scheduled by the DEA into five categories, with Schedule I having the highest abuse potential and Schedule V the lowest. Drugs are also classified based on their teratogenic risk to a fetus from A to X.
1) Pharmacology has its origins in ancient times when various cultures used plants and herbs to treat medical issues. It developed into a distinct discipline in the 19th century with the isolation of active compounds from natural substances and study of their effects.
2) John Jacob Abel established the first pharmacology department in the United States in 1890, advancing the field of modern pharmacology. Regulations and standards for drug development, labeling, and safety have strengthened over time through organizations like the USP and laws.
3) Nurses play a key role in pharmacology due to their direct involvement in patient care across all settings. Understanding how different factors influence individual drug responses is important for safe administration.
This chapter discusses principles of drug administration for nurses. It outlines the nursing process for drug administration including nurse responsibilities such as understanding classifications, actions, side effects, and ensuring safe preparation and administration. Common medication errors are also reviewed. The chapter then covers allergic reactions, the five rights of administration, routes of administration including enteral, topical and parenteral, and special considerations for various types of drug delivery such as transdermal patches, ophthalmic drops, and otic drops.
