What You'll Learn

Administering treatments and medications
Nurses play a central role in hospitals by providing direct patient care and administering treatments. They may work in intensive-care units, providing close monitoring and treatment for patients with serious, complex, and acute illnesses or injuries. Nurses also manage wound care, including consultations, cleaning, and bandaging. They may also be responsible for performing intubation, a life-saving procedure for patients who cannot breathe on their own, and venipuncture, a common invasive procedure for drawing blood samples.
In addition to these procedures, nurses are often responsible for administering medications as directed by physicians. They ensure that patients receive their prescribed medications on time and monitor patients for any side effects or reactions. Nurses also educate patients and their families about their medications and treatment plans, providing essential information and answering any questions they may have.
Nurses also have a crucial role in patient intake, which involves taking and recording vital signs, obtaining health histories, and performing physical exams. This information is vital for developing and evaluating patient care plans in collaboration with the medical team. Nurses' ability to coordinate care across multiple specialties ensures that patients receive the highest quality of care throughout their hospital stay.
The role of nurses in administering treatments and medications is essential for ensuring patient safety and well-being. Their dedication, precision, and coordination skills contribute to effective patient care and positive outcomes.

Drawing blood and taking vitals
When drawing blood, nurses must first identify the most prominent vein, which can vary depending on their skill and comfort level. They then gather the necessary supplies, such as tubes, syringes, and tourniquets. The process involves inserting a needle into the identified vein and attaching the required tubes or syringes to collect the specified volume of blood. Nurses must also be adept at disinfecting the area, releasing the tourniquet, removing the needle, and applying pressure to stop bleeding. Proper disposal of contaminated materials and timely delivery of blood specimens to the laboratory are also crucial steps.
Taking vitals is another critical component of a nurse's duties. This includes monitoring and recording a patient's vital signs, such as temperature, blood pressure, pulse rate, and respiratory rate. Nurses also play a vital role in observing, assessing, and documenting symptoms, reactions, and progress. They work alongside doctors to coordinate treatment plans and ensure patients receive the correct medications at the right time.
Nurses often spend more time with patients than treating physicians, allowing them daily opportunities to positively impact their patients' lives. They are adaptable and educated, continuously monitoring and evaluating patients while coordinating with multiple specialists to ensure effective recovery. Nurses' capabilities extend beyond stereotypes, and they can be found in various healthcare settings, including hospitals, clinics, schools, and homes, delivering care and improving lives.
The ability to draw blood and take vitals are fundamental skills in a nurse's repertoire, contributing to their overall role in promoting health, preventing disease, and providing essential care to patients across diverse settings.

Patient care planning
The nursing process, established by Ida Jean Orlando in 1958, is a systematic approach to patient care. It involves five sequential steps: assessment, diagnosis, planning, implementation, and evaluation. During the assessment phase, nurses collect both subjective and objective data. Subjective data includes verbal statements from the patient about their health goals and preferences, while objective data covers measurable factors such as vital signs, intake and output, and height and weight. Nurses must also involve the patient's family members or caregivers in this process.
Following assessment, nurses formulate a diagnosis and develop a care plan in collaboration with doctors and other specialists. This may include patient intake, obtaining measurements and health histories, and administering medications or treatments as ordered by physicians. Nurses must ensure that patients receive the correct treatments and medications at the right time, coordinating multiple treatment plans and records for different patients. They also continuously monitor and evaluate patients' progress, making necessary adjustments to the care plan as health statuses and goals evolve.
Nursing documentation is an essential component of patient care planning. It outlines observations, nursing actions, and instructions for clients and their families. Proper documentation ensures continuity of care, provides evidence of the care provided, and helps track patient progress. Nurses must also be prepared to adapt their documentation methods, as seen in case studies where hospitals simplified forms or switched to free-text, handwritten care plans to improve efficiency and compliance with requirements.
Overall, patient care planning by nurses involves a holistic approach, addressing the physical, psychological, social, and spiritual needs of the patient. It requires critical thinking, intuition, and a strong commitment to helping others.

Patient education
Nurses tailor their educational approach to each patient's needs, accommodating different learning styles and health literacy levels. They simplify medical information, using plain language and avoiding medical jargon to ensure patients understand and retain the information. This may include providing written, verbal, or visual instructions, as well as hands-on demonstrations.
Nurses teach patients about a range of topics, including medication management, wound care, self-care practices, recognising warning signs, and lifestyle changes. For example, nurses provide comprehensive demonstrations on wound care techniques, emphasising cleanliness and monitoring for signs of infection. They also ensure patients understand medication dosages, timing, and potential side effects.
In addition, nurses educate patients on how to manage their specific health conditions effectively. This may involve instructing a new mother on how to bathe a newborn or teaching an adult with chronic heart disease how to manage their condition. Nurses also address any physical, mental, or emotional impairments that may impact a patient's ability to learn.
Nurses also play a role in educating the community on various health and medical issues, promoting health literacy and empowering individuals to make informed choices about their health. Overall, patient education by nurses leads to better patient outcomes, improved health literacy, and increased patient confidence in managing their health.

Wound care
The role of a wound care nurse extends beyond wound cleaning and dressing. They are responsible for selecting appropriate dressings that promote healing and protect the wound from bacteria and contaminants. This requires staying abreast of the latest research and advancements in wound care products. Additionally, wound care nurses educate patients and their families on proper wound care techniques, empowering them to manage their wounds effectively outside the hospital setting.
To become a certified wound care nurse, individuals must pursue specialised education and training. This includes obtaining a Bachelor of Science in Nursing (BSN) degree, completing accredited wound care programs, and gaining clinical experience. Certifications, such as the Wound, Ostomy, and Continence Nursing Certification (WOCNC), further enhance their credentials and expertise.
