Critical thinking is the ability to think clearly and rationally about what to do or what to believe. It involves gathering information, analyzing it, and making sound judgments. Critical thinking is an essential skill for nurses, as it allows them to provide the best possible care for their patients.
Critical Thinking in the Nursing Process
The nursing process is a systematic approach to nursing care that consists of five steps: assessment, diagnosis, planning, implementation, and evaluation. Critical thinking is used at every step of the nursing process.
Assessment
During the assessment phase, nurses gather data about the patient’s health status. This data can come from a variety of sources, including the patient’s medical history, physical examination, and laboratory results. Nurses use critical thinking to analyze the data and identify patterns and trends.
For example, a nurse may assess a patient who has been admitted to the hospital with shortness of breath. The nurse gathers data about the patient’s medical history, including any known heart or lung conditions. The nurse also performs a physical examination, which reveals that the patient has a rapid heart rate and respiratory rate. The nurse also orders laboratory tests, which reveal that the patient has an elevated white blood cell count.
The nurse analyzes this data and determines that the patient is likely experiencing pneumonia. This is because pneumonia is a common cause of shortness of breath, rapid heart rate, respiratory rate, and elevated white blood cell count.
Diagnosis
Once the nurse has assessed the patient, they develop nursing diagnoses. Nursing diagnoses are statements that describe the patient’s health problems and the nurse’s role in addressing those problems.
For example, the nurse in the above example may develop the following nursing diagnoses:
- Impaired gas exchange related to pneumonia
- Decreased activity tolerance related to pneumonia
- Risk for infection related to pneumonia
Planning
After developing nursing diagnoses, the nurse develops a care plan. The care plan outlines the goals and interventions that the nurse will use to address the patient’s needs.
For example, the nurse in the above example may develop the following goals and interventions:
- Goal: Improve gas exchange.
- Interventions:
- Administer oxygen as prescribed.
- Position the patient in a semi-Fowler’s position.
- Encourage the patient to cough and deep breathe.
- Goal: Increase activity tolerance.
- Interventions:
- Help the patient to perform activities of daily living as tolerated.
- Gradually increase the patient’s activity level as tolerated.
- Goal: Prevent infection.
- Interventions:
- Administer antibiotics as prescribed.
- Monitor the patient for signs and symptoms of infection.
Implementation
The implementation phase is when the nurse carries out the interventions that were outlined in the care plan. The nurse must use critical thinking to ensure that the interventions are carried out safely and effectively.
For example, the nurse in the above example would need to use critical thinking to determine the appropriate amount of oxygen to administer to the patient. The nurse would also need to monitor the patient’s response to the oxygen and adjust the amount as needed.
Evaluation
The evaluation phase is when the nurse assesses the patient’s response to the interventions and makes adjustments to the care plan as needed.
For example, the nurse in the above example would evaluate the patient’s gas exchange by monitoring the patient’s oxygen saturation and respiratory rate. The nurse would also evaluate the patient’s activity tolerance by monitoring the patient’s heart rate and blood pressure during activity. If the patient’s gas exchange or activity tolerance does not improve, the nurse may need to adjust the care plan.
Critical Thinking in Patient Care
Critical thinking is also used in all aspects of patient care, including:
- Making clinical decisions: Nurses must use critical thinking to weigh the risks and benefits of different treatment options and make decisions that are in the patient’s best interest.
- Prioritizing care: Nurses must use critical thinking to identify the patient’s most urgent needs and prioritize care accordingly.
- Troubleshooting problems: Nurses must use critical thinking to identify the root cause of problems and develop and implement solutions.
- Communicating with patients and families: Nurses must use critical thinking to communicate effectively with patients and families and provide them with the information they need to make informed decisions about their care.
Critical Thinking in Professional Development
Critical thinking is also essential for professional development. Nurses must be able to evaluate research, implement evidence-based practice, participate in quality improvement initiatives, and advocate for their patients.
- Evaluating research: Nurses must use critical thinking to evaluate the quality of research studies and assess the relevance of research findings to nursing practice. Nurses must also be able to determine whether research findings can be applied to individual patients.
- Implementing evidence-based practice: Nurses must use critical thinking to identify the best available evidence for a particular clinical situation. Nurses must also be able to adapt the evidence to the individual patient’s needs and evaluate the effectiveness of evidence-based practice interventions.
- Participating in quality improvement initiatives: Nurses must use critical thinking to identify areas for improvement in nursing practice. Nurses must also be able to develop and implement interventions to improve quality and measure and evaluate the outcomes of quality improvement initiatives.
- Advocating for patients: Nurses must use critical thinking to educate patients about their rights and options. Nurses must also be able to help patients to access the care they need and speak out on behalf of patients who are unable to advocate for themselves.
Real-World Examples of Critical Thinking in Nursing
Here are some real-world examples of how critical thinking is used in nursing:
- A nurse is caring for a patient who has been admitted to the hospital with pneumonia. The patient is on oxygen, but their respiratory rate is still elevated. The nurse uses critical thinking to determine that the patient may be experiencing respiratory distress. The nurse calls the physician to assess the patient and order appropriate interventions.
- A nurse is caring for a patient who has been diagnosed with cancer. The patient is scheduled to undergo surgery, but they are very anxious about the procedure. The nurse uses critical thinking to educate the patient about the surgery and answer their questions. The nurse also provides emotional support to the patient and their family.
- A nurse is working on a unit that is caring for patients with COVID-19. The nurse notices that there is a high rate of infection among the patients on the unit. The nurse uses critical thinking to identify the root cause of the problem and develop interventions to reduce the rate of infection. The nurse also works with other members of the healthcare team to implement the interventions and evaluate their effectiveness.
Tips for Developing Critical Thinking Skills
There are a number of things that nurses can do to develop their critical thinking skills, including:
- Be curious and ask questions.
- Be open to new ideas and perspectives.
- Be willing to challenge the status quo.
- Be able to think outside the box.
- Be able to weigh the evidence and make informed decisions.
- Be able to communicate your thoughts and ideas clearly and concisely.
Conclusion
Critical thinking is an essential skill for nurses. It allows nurses to provide the best possible care for their patients. Nurses can develop their critical thinking skills by being curious, asking questions, being open to new ideas, challenging the status quo, thinking outside the box, weighing the evidence, and communicating effectively.
