nursing citical thinking WEEK 6

What is critical thinking in nursing?

A continuous process of open-mindedness, inquiry, and perseverance used to analyze information, question assumptions, and make sound conclusions.

What three types of thinking are required for critical thinking?

1. Creative

2. reflective

3. analytical thinking.

What three skills are essential for critical thinking?

Questioning, probing, and judging.

What are the three basic actions involved in critical thinking?

1. Recognize an issue

2. analyze and evaluate information

3. make sound conclusions.

Why is critical thinking important in nursing?

It prevents and resolves problems,

promotes safe and effective care

decreases errors in clinical judgments.

What is the difference between a thought-oriented and a task-oriented nurse?

A thought-oriented nurse analyzes patient needs and reasons through care rather than simply completing tasks.

What should a nurse do when a patient is not improving despite treatment?

Continue questioning why the patient is not improving and evaluate the patient's condition and response to treatment.

How can a nurse develop critical-thinking skills?

1. Hold high standards

2. take responsibility for learning

3. develop interpersonal skills

4. practice technical skills

What five components are necessary for critical thinking in nursing?

Knowledge base, experience, nursing process competencies, attitudes, and standards.

What are the two types of standards involved in critical thinking?

Intellectual standards (rational thought) and professional standards (ethics and evidence).

What is the nursing process?

A systematic, patient-centered problem-solving approach used to diagnose and treat human responses to actual or potential health problems.

What are the five steps of the nursing process in order?

Assessment, Diagnosis, Planning, Implementation, Evaluation (ADPIE).

Why is the nursing process considered cyclical?

Evaluation may identify the need to reassess the patient and repeat the nursing process.

What occurs during the assessment phase?

The nurse systematically collects subjective and objective data to evaluate the patient's health status.

What is the primary source of assessment data?

The patient, through the health history interview and physical assessment.

What are secondary sources of assessment data?

Family members, significant others, other healthcare professionals, and medical records.

What occurs during the diagnosis phase of the nursing process(ADPIE)?

The nurse analyzes assessment data and uses diagnostic reasoning to identify patient problems.

What are the five steps of diagnostic reasoning?

1. Organize cues

2. generate possible diagnoses

3. compare cues with diagnose

4. collect focused data

5. validate diagnoses.

What is the difference between a nursing diagnosis and a medical diagnosis?

A nursing diagnosis identifies a patient problem that guides nursing interventions;

a medical diagnosis identifies a medical condition. Example: Ineffective airway clearance vs. pneumonia.

What occurs during the planning phase?

The nurse establishes priorities, identifies expected outcomes, and develops a patient-centered plan of care.

What characteristics should expected patient outcomes have?

They should be measurable, realistic, patient-focused, prioritized, and documented.

What is an example of a measurable expected outcome?

The patient will ambulate 50 feet with assistance within 24 hours.

What occurs during the implementation phase?

The nurse initiates the care plan, evaluates the patient's response, and documents care.

What must nurses understand when implementing interventions?

The interventions must be evidence-based, and nurses must understand their rationale.

What occurs during the evaluation phase?

The nurse compares the patient's assessment after interventions with expected outcomes to determine whether they were met, considering positive and unintended or negative consequences.

What is clinical judgment?

The process of making nursing decisions using nursing knowledge, other disciplinary knowledge, critical thinking, and clinical reasoning.

What are the six steps of the NCSBN Clinical Judgment Measurement Model?

Recognize Cues → Analyze Cues → Prioritize Hypotheses → Generate Solutions → Take Action → Evaluate Outcomes.

What occurs during Recognize Cues?

Identify relevant and important patient information from different sources.

What occurs during Analyze Cues?

Organize and connect recognized cues to the patient's clinical presentation.

What occurs during Prioritize Hypotheses?

Evaluate possible explanations for the patient's condition and rank them by priority.

What occurs during Generate Solutions?

Identify expected patient outcomes and determine possible nursing interventions.

What occurs during Take Action?

Implement solutions that address the highest-priority patient problems.

What occurs during Evaluate Outcomes?

Compare the patient's observed outcomes with expected outcomes to determine the effectiveness of interventions.

A postoperative patient's BP drops from 124/78 to 84/50 mmHg. What additional cues suggest a serious complication?

HR 118 bpm, RR 22/min,

cool pale clammy skin,

lightheadedness,

urine output of 15 mL/hr.

A postoperative patient has hypotension, tachycardia, pale skin, and decreased urine output. What is the priority hypothesis in the lecture?

Postoperative hemorrhage leading to hypovolemic shock.

What possible causes should the nurse consider when analyzing the postoperative patient's abnormal findings?

Surgical-site bleeding or hemorrhage, fluid loss, and hypovolemic shock.

What immediate actions does the lecture identify for suspected postoperative hemorrhage?

Stay with the patient, call for help, apply oxygen, and prepare to administer IV fluids or blood as ordered.

What additional assessments and interventions should the nurse prepare for in suspected postoperative hemorrhage?

Check the surgical dressing and drainage tubes, ensure IV patency, and contact the rapid response team and surgeon.

What findings indicate improvement after interventions for the postoperative patient?

BP improves to 102/68 mmHg, alertness increases, skin becomes warmer, and urine output increases.

A patient reports feeling hungry but does not eat when food is served. What should the nurse do first?

Assess why the patient is not eating rather than making assumptions about the patient's needs.

A nurse is caring for a patient whose condition has not improved despite prescribed treatment. Which action best demonstrates critical thinking?

A. Continue the current interventions without changes
B. Question why the patient is not improving and reassess the situation
C. Wait until the healthcare provider changes the treatment
D. Document that the treatment has been ineffective

Correct Answer: B

Rationale: Critical thinking involves continual inquiry, analyzing information, questioning assumptions, and making sound conclusions. The lecture specifically gives persistently asking why a patient is not improving despite treatment as an example of critical thinking.

Which sequence correctly represents the nursing process?

A. Assessment → Planning → Diagnosis → Implementation → Evaluation
B. Diagnosis → Assessment → Planning → Evaluation → Implementation
C. Assessment → Diagnosis → Planning → Implementation → Evaluation
D. Planning → Assessment → Diagnosis → Implementation → Evaluation

Correct Answer: C

Rationale: The nursing process follows ADPIE: Assessment, Diagnosis, Planning, Implementation, Evaluation. It is continuous and cyclical because evaluation can lead back to reassessment.

A nurse obtains information about a patient's current symptoms directly from the patient. Which type of data source is the nurse using?

A. Primary source
B. Secondary source
C. Professional source
D. Objective source

Correct Answer: A

Rationale: The patient is the primary source of assessment data. Secondary sources include family members, significant others, healthcare professionals, and medical records.

After collecting assessment data, the nurse organizes the patient's cues, generates possible diagnoses, and compares the cues with the possible diagnoses. Which phase of the nursing process is occurring?

A. Assessment
B. Diagnosis
C. Planning
D. Evaluation

Correct Answer: B

Rationale: During Diagnosis/Analysis, the nurse analyzes assessment data and uses diagnostic reasoning to identify patient problems. This includes organizing cues, generating possible diagnoses, comparing cues, collecting focused data, and validating diagnoses.

Which statement is the best example of an expected outcome developed during the planning phase?

A. "The nurse will encourage the patient to ambulate."
B. "The patient should try to walk more frequently."
C. "The patient will ambulate 50 feet with assistance within 24 hours."
D. "The nurse will assess the patient's ability to walk."

Correct Answer: C

Rationale: Expected outcomes should be measurable, realistic, patient-focused, prioritized, and documented. "Patient will ambulate 50 feet with assistance within 24 hours" provides a specific behavior, distance, and time frame.

A nurse teaches a postoperative patient how to use an incentive spirometer to help prevent pneumonia. Which phase of the nursing process does this represent?

A. Assessment
B. Diagnosis
C. Planning
D. Implementation

Correct Answer: D

Rationale: Implementation is the action phase of the nursing process. The lecture specifically uses teaching incentive spirometry after surgery as an example of implementation.

A nurse administers an analgesic to a patient who reports pain. Thirty minutes later, the nurse reassesses the patient's pain level. Which phase of the nursing process is demonstrated by the reassessment?

A. Diagnosis
B. Planning
C. Implementation
D. Evaluation

Correct Answer: D

Rationale: During Evaluation, the nurse determines whether expected outcomes were met by comparing the patient's condition after an intervention with the expected outcome. Reassessing pain after analgesic administration is the lecture's example.

A postoperative patient has a BP of 84/50 mmHg, HR 118/min, cool pale clammy skin, lightheadedness, and urine output of 15 mL during the last hour. According to the clinical judgment model, what should the nurse identify as the priority hypothesis?

A. Anxiety related to hospitalization
B. Postoperative hemorrhage leading to hypovolemic shock
C. Acute postoperative pain
D. Impaired physical mobility

Correct Answer: B

Rationale: The lecture identifies these cues as indicating possible postoperative hemorrhage leading to hypovolemic shock. During Prioritize Hypotheses, the nurse determines which possible problem is most likely and most dangerous. This condition is life-threatening and requires immediate attention.

A nurse identifies hypotension, tachycardia, pale skin, and decreased urine output in a postoperative patient and connects these findings with possible blood loss. Which step of the NCSBN Clinical Judgment Measurement Model is the nurse performing?

A. Recognize Cues
B. Analyze Cues
C. Generate Solutions
D. Evaluate Outcomes

Correct Answer: B

Rationale: Analyze Cues means organizing and linking recognized cues to the patient's clinical presentation. Simply identifying the abnormal findings would be Recognize Cues; connecting those findings with possible blood loss represents Analyze Cues.

A nurse provides interventions to a patient experiencing a postoperative complication. Which action best demonstrates the Evaluate Outcomes step of clinical judgment?

A. Identifying that the patient's BP is 84/50 mmHg
B. Determining that hemorrhage may be occurring
C. Preparing to administer IV fluids as ordered
D. Comparing the patient's current BP and urine output with the expected outcomes

Correct Answer: D

Rationale: Evaluate Outcomes requires comparing the patient's observed outcomes with expected outcomes. Improvement in blood pressure, alertness, skin warmth, and urine output would indicate that the interventions are having the desired effect.
