Explanation

The Modified Early Warning Score (MEWS) is a standardized scoring system used to detect early signs of clinical deterioration in hospitalized patients.
A score of 7 or more indicates a high or critical risk of severe illness, cardiac arrest, or death, as the patient is physiologically unstable.
This high score serves as a trigger for an immediate emergency response, typically involving a Rapid Response Team (RRT) or Medical Emergency Team (MET) for urgent assessment and intervention.

Option B: This action is for patients with a low MEWS score, typically in the 0-4 range, who are clinically stable.
Option C: A high MEWS score indicates severe physiological derangement, which is the opposite of a 'normal' state suitable for discharge. This action would be unsafe.
Option D: This response is inadequate for a critically deteriorating patient. The priority is urgent assessment and stabilization, not just administering routine medications.

Visual 2: Flowchart: An escalation pathway diagram showing the specific actions to take for different MEWS score ranges (e.g., Score 0-4 -> Ward-based response; Score 5-6 -> Urgent senior review; Score 7+ -> Emergency MET/RRT call).

Clinical Relevance

Nursing practice connection: Use the key finding related to Interpretation of Modified Early Warning Score (MEWS) and corresponding clinical actions to guide bedside assessment, documentation, and the next nursing action.
Nurses are at the forefront of patient monitoring and are often the first to calculate the MEWS. Their ability to correctly interpret the score and initiate the escalation protocol is a critical patient safety function.
Failure to recognize and act on a high MEWS score is a leading cause of preventable adverse events, in-hospital cardiac arrests, and patient deaths.
What if the patient's score was 5? In that case, the patient is at a medium-to-high risk. The nurse should conduct an urgent assessment, increase the frequency of vital signs monitoring (e.g., to hourly), and promptly inform the senior medical staff or charge nurse, preparing for a potential transfer to a higher level of care like an HDU.

How to Approach the Question

First, identify the core of the question: it asks for the interpretation and action for a specific value (MEWS > 7) from a clinical scoring tool.
Recall the purpose of early warning scores like MEWS: to detect patient deterioration. A higher score universally indicates a higher risk.
Categorize the score of 'more than 7' as a high-risk or critical value.
Evaluate the options based on this high-risk level. The option 'High risk patient requiring immediate attention' directly aligns with the purpose of a critical score.
Systematically eliminate the other options. 'Low risk' and 'Normal' are incorrect because the score is high. 'Start routine medication' is an insufficient action for an emergency situation.
