Explanation

Listen in Hindi

• Pain is formally recognized as the fifth vital sign in modern healthcare, mandating its regular assessment alongside the traditional four vital signs.
• The inclusion of a Visual Analogue Scale (VAS) score in the patient's data is a direct reference to pain assessment, as VAS is a tool used to quantify pain intensity.
• A VAS score of 8 out of 10 is classified as severe pain, highlighting the clinical urgency and confirming the focus on pain as a critical patient parameter.

Why Other Options Were Wrong

• Option A: Respiration is one of the four traditional vital signs, not the fifth. It measures the number of breaths a person takes per minute.
• Option B: Blood pressure is one of the four traditional vital signs, not the fifth. It measures the pressure of circulating blood on the walls of blood vessels.
• Option D: Temperature is one of the four traditional vital signs, not the fifth. It measures the degree of heat of the human body.

• Visual 2: Infographic - The five vital signs, with icons for Temperature, Pulse, Respiration, Blood Pressure, and Pain, illustrating that all five are standard components of patient assessment.

Clinical Relevance

• Nursing practice connection: Prioritize focused assessment, early escalation, and real-time monitoring when managing Identification of the fifth vital sign and its assessment in acute care settings.
• Routinely assessing pain as the fifth vital sign ensures that it is not overlooked, leading to better patient comfort, faster recovery, and reduced physiological stress and complications.
• Unmanaged severe pain can lead to adverse physiological effects, including increased heart rate, blood pressure, and oxygen demand, potentially worsening the patient's condition, especially in the ICU.
• What if the patient was non-verbal or intubated? The nurse would use a behavioral pain scale like the FLACC (Face, Legs, Activity, Cry, Consolability) scale or the Critical-Care Pain Observation Tool (CPOT) to assess for non-verbal cues of pain.

How to Approach the Question

• First, identify the core question: it asks to name the 'fifth vital sign'.
• Recall the four traditional vital signs: temperature, pulse, respiration, and blood pressure.
• Recognize that modern nursing practice has added a fifth component to this routine assessment.
• Analyze the clinical cues provided in the stem: 'VAS score is 8'.
• Identify that VAS stands for Visual Analogue Scale, a tool used exclusively to measure pain intensity.
• Connect the specific clue (VAS score) to the concept of pain assessment, which directly leads to the conclusion that pain is the fifth vital sign.

Concept Tested & Keywords

• Concept Tested: Identification of the fifth vital sign and its assessment.
• Stem keywords: fifth vital sign, VAS score, ICU
• Lead-in keywords: Which is
• Clinical cues: VAS score of 8: This is a direct clue pointing to pain assessment, as VAS is a pain scale. A score of 8 signifies severe pain.
