Summary
Nurses can use this pre-anesthesia screening questionnaire to accurately identify patients needing further evaluation. The tool demonstrates good validity, ensuring appropriate anesthetic care planning before surgery.
Area of Science:
- Anesthesiology
- Nursing Practice
- Patient Screening
Background:
- Pre-operative assessment is crucial for safe anesthesia.
- Nurses play a key role in patient evaluation.
- A validated screening tool can streamline pre-anesthetic consultations.
Purpose of the Study:
- To develop and validate a screening questionnaire for nurses.
- To determine patient eligibility for pre-anesthetic evaluation.
- To assess the accuracy of patient responses compared to anesthesiologist assessments.
Main Methods:
- Development of a screening questionnaire for nurses.
- Assessment of agreement between questionnaire responses and anesthesiologist evaluations.
- Statistical analysis using Kappa coefficient and percentage agreement based on response prevalence.
Main Results:
- Criterion validity was excellent/good for most questions (5-95% prevalence).
- The question regarding kidney disease showed lower validity.
- Some questions with low prevalence (<5%) also demonstrated adequate validity, with specific exceptions.
Conclusions:
- The developed questionnaire is a reliable tool for nurses.
- It effectively identifies patients requiring pre-anesthetic assessment.
- Implementation can improve the efficiency of pre-operative care.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

01:23Assessment of Respiration
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

01:10Pre-Procedural Guidelines for Assessing Blood Pressure
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the patient.
01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
