Question 3

The unit in-charge is following up an incident report for a patient who fell down from the bed to be written by the nurse.

Which of the following actions if done by the nurse needs to be corrected?



Answer : D

When an incident such as a patient fall occurs, specific protocols must be followed to ensure proper documentation and quality improvement processes.

Writing the Incident Report Immediately: The nurse should document the incident as soon as possible to ensure accurate details are captured.

Investigating the Root Cause of the Incident: This is essential to prevent future occurrences and improve patient safety. It involves a thorough analysis of the factors that led to the incident.

Writing the Incident Report by the Assigned Nurse: The nurse who witnessed or discovered the incident is typically responsible for documenting it, ensuring first-hand accuracy.

Documenting the Incident Report in Patient's Record: This is incorrect. Incident reports are meant for internal use to track and analyze incidents and should not be included in the patient's medical record. Including it in the patient's record can potentially compromise confidentiality and affect the patient's care.

Question 5

A nurse is preparing to collect a throat culture for a middle-aged male patient.

The nurse is aware that the swabbing should be collected from:



Answer : D

Purpose of Throat Culture: A throat culture is performed to detect the presence of pathogens (like bacteria) that cause infections such as strep throat.

Correct Technique:

Uvula and Soft Palate: These are not the primary sites for collecting throat cultures.

Any site of Oral Cavity Mucosa: This is too broad and non-specific.

Tongue and Buccal Mucosa: These sites are not typically infected in throat infections and do not provide accurate culture results.

Oropharynx and Tonsillar Region: The mucosa of the oropharynx and tonsillar region is the most common site of infection in throat infections, making it the appropriate site for swabbing.

Procedure: The nurse should gently swab the oropharynx and tonsillar area, avoiding the tongue and other parts of the oral cavity to avoid contamination and ensure accurate results.

Conclusion: The correct site for collecting a throat culture is the mucosa of the oropharynx and tonsillar region, ensuring the detection of the causative pathogens. Reference: Clinical nursing skills textbooks, NCLEX-RN review guides, guidelines for throat culture collection.
