Roles and Responsibilities of Healthcare Professionals

Nurses, Phlebotomists, and HCAs are all playing an important role in the healthcare field, each with distinct responsibilities and qualifications. Below is a brief overview of the roles and responsibilities of each Healthcare Professional.


A nurse plays a crucial role in the healthcare industry and is responsible for providing a wide range of patient care and support. Their duties can vary depending on their specialisation and the healthcare setting in which they work. 

Nurses are directly involved in providing care to patients, including monitoring their vital signs, administering medications, dressing wounds, and assisting with personal hygiene and daily activities. They also perform comprehensive assessments of patients to identify their health needs and develop appropriate care plans. Nurses are also responsible for administering treatments prescribed by physicians. 

They work collaboratively with other healthcare professionals, such as doctors, therapists, and social workers, to provide comprehensive care to patients.

Some nurses may choose to specialise in specific areas such as pediatric nursing, critical care, oncology, mental health, or geriatric care, and their duties would align with their chosen field.

Health Care Assistant

An HCA is a healthcare professional who provides basic patient care under the supervision of a doctor,  registered nurses, or other healthcare professionals. HCAs assist patients with activities of daily living, such as bathing, dressing, eating, and mobility. 

They are often responsible for measuring and recording patients’ vital signs, such as blood pressure, temperature, pulse rate, and respiratory rate, and they keep a close eye on patients and promptly report any changes in their condition or any concerns they observe to the nursing staff.

Under supervision, HCAs may support healthcare professionals during medical procedures or examinations, ensuring patients are comfortable and assisting as needed. 

It’s important to note that the specific tasks and scope of responsibilities for HCAs can differ based on the country, state regulations, and the policies of the healthcare facility they work in.


A phlebotomist is a medical professional who specializes in collecting blood samples from patients. Their primary responsibility is to draw blood for various purposes, such as medical tests, diagnostic procedures, blood donations, and research. They work as part of a larger healthcare team, and they often collaborate with doctors, nurses, and laboratory staff to ensure the accuracy and efficiency of the blood collection process.

Phlebotomists use various methods to draw blood from patients, including venipuncture (piercing a vein with a needle), fingersticks, and heelsticks (for infants), and follow proper procedures to ensure the safety and comfort of the patient.

They must be skilled in communication and patient interaction, as they often work directly with patients who may be nervous or anxious about having their blood drawn. Before the blood draw, phlebotomists may explain the procedure to the patient, answer any questions or concerns, and ensure the patient is in a comfortable position.


In summary, a nurse has a broader scope of practice and responsibilities, including patient care, education, and medication administration. An HCA provides supportive care to patients and assists healthcare professionals with various tasks but does not have the same level of training and authority as a nurse or phlebotomist, and a phlebotomist specialises in drawing blood for diagnostic purposes.
