Nurses are the backbone of the healthcare system, providing essential care, support, and expertise in a wide range of settings, from hospitals to community clinics. Their role goes beyond administering medication and monitoring vital signs; they are patient advocates, educators, critical thinkers, and caregivers. Nurses work collaboratively with physicians, therapists, pharmacists, and other healthcare professionals to deliver holistic and patient-centred care. They may specialize in areas such as medical-surgical nursing, pediatric nursing, psychiatric nursing, or critical care nursing, depending on their interests, training, and career goals. In hospitals, nurses typically work in shifts to ensure 24/7 coverage and continuity of care for patients. They are responsible for patient assessment, including physical exams, checking vital signs, evaluating mental status, and collecting lab samples. They also provide direct patient care, assist with activities of daily living, and educate patients about their health and recovery.

What You'll Learn

Nurses provide patient care
Nurses also play a crucial role in patient communication and education, providing continuous support and guidance throughout the healthcare journey. They instruct patients on self-care, such as how to inject insulin or change a colostomy bag, and teach them to recognize warning signs of health issues. Nurses advocate for their patients, addressing lifestyle changes, managing chronic conditions, and alleviating anxiety about upcoming procedures. They are often the patient's main point of contact in the hospital and spend the most time with them, so they are well-positioned to provide this support.
Nurses also have specialized roles. For example, wound care nurses manage wound-care programs and provide direct patient care and education. Dialysis nurses care for patients with kidney issues, assisting with dialysis treatments and monitoring progress. Infection control nurses work to prevent and control infectious diseases within healthcare settings, developing policies and conducting staff training.
Nurses provide essential care, support, and expertise, and their specific duties depend on their setting and specialization. They are patient advocates, educators, critical thinkers, and caregivers, and their role is central to the functioning of the healthcare system.

They are often the patient's primary caregiver and advocate, spending the most time with them and coordinating their care. Nurses may work with doctors, residents, nursing assistants, home health aides, speech therapists, occupational therapists, and other nurses.
Nurses are often responsible for administering medications, monitoring vital signs, and recording symptoms and patient information.

Administer medicine
Administering medication is a key part of a nurse's role. Nurses are often the last line of defence in ensuring that medication is correctly prescribed, dispensed, and administered. This means that nurses bear significant responsibility for patient safety.
Nurses are trained to administer medication in a variety of ways, including oral, intramuscular, intravenous, topical, and subcutaneous injection. Nurses also administer medication via central venous catheters, patient-controlled analgesia (PCA), epidural infusions, and intrathecal administration. The method of administration will depend on the medication and the patient's needs. For example, a patient in the ICU may require a nebuliser, while a patient with a gastric tube will need medication administered through that route.
Before administering medication, nurses must verify the patient's identity and the medication's details. This includes checking the patient's name, the medication's name, dosage, and expiration date. Nurses also need to be aware of any allergies or potential side effects the patient may experience. Nurses should also follow any agency policies and procedures for medication administration, including using electronic systems for medication orders and records where available.
Nurses play a vital role in patient care, often spending more time with patients than physicians. They work in a variety of settings, including hospitals, clinics, nursing homes, and community health centres, and often care for multiple patients simultaneously. Their role includes providing medical care, promoting health, preventing illness, and collaborating with other healthcare professionals to deliver holistic patient-centred care.

Check vital signs
Checking vital signs is a fundamental skill for nurses, and it is one of the most basic aspects of nursing care. Vital signs are critical health indicators that offer insights into a patient's overall health and organ function. They are routinely assessed by nurses and nursing assistants in all healthcare settings. These include measurements of a patient's heart rate, respiratory rate, blood pressure, and temperature.
Nurses must follow protocol when taking vital signs to ensure accurate results. They must also be mindful of time management, especially in emergencies or during routine check-ups, where time is a factor. Nurses should also ask the patient to rate their pain on a scale of 0 to 10 and inquire about the location and quality of the pain if it exists. This information can help nurses understand how well a patient is doing and determine if they are improving or worsening.
In addition to the core vital signs, nurses may also be responsible for other tasks related to vital sign monitoring, such as oral hygiene, temperature checks, blood tests, and monitoring urine output. These tasks can vary depending on the patient and the unit in which the nurse is working. For example, nurses in the intensive care unit (ICU) may have different tasks and monitoring procedures compared to those in the emergency room (ER).
Vital sign monitoring is an important aspect of nursing care, and nurses must be proficient in this skill to ensure patient safety and well-being. It is a balance between thoroughness and efficiency, and nurses must be able to interpret the results to make informed decisions about patient care.

Educate patients
Nurses play a critical role in educating patients about their health conditions, treatment plans, and preventive measures, empowering them to actively participate in their care journey. They provide essential information about medications, follow-up appointments, and self-care practices, which helps patients effectively manage their health post-discharge. This education improves overall patient satisfaction and reduces the risk of complications and hospital readmissions.
Nurses must tailor their teaching methods to the individual needs of each patient. For example, patients with physical, mental, or emotional impairments may require large-print materials, visual aids, or hands-on learning approaches. Language barriers should also be considered, with resources provided in the patient's native language or through translation apps.
The "teach-back" method is an effective strategy where nurses ask patients to repeat information in their own words to ensure comprehension. Nurses should also be mindful of the amount of information provided at once, as patients may feel overwhelmed. It is important to involve family members in patient education, as they play a critical role in healthcare management and can help reinforce instructions.
Nurses also educate patients on lifestyle choices, empowering them to make healthier decisions. By understanding patients' learning styles and managing expectations, nurses can provide effective education without becoming personally invested in the outcome. This aspect of nursing can be challenging but is ultimately rewarding, as it builds trust and improves patient outcomes.
