Correct Answer is A

Explanation

A. A decrease in Glasgow Coma Scale (GCS) score from 13 to 9 indicates worsening neurological status and possible deterioration, which requires immediate medical evaluation.
B. Pupils that are equal, round, and reactive are normal findings and not a concern.
C. A mild drop in heart rate from 76 to 70 bpm is within normal limits and not immediately concerning.
D. Repeated requests for narcotic pain medications may warrant assessment for pain or misuse but do not require immediate reporting compared to a significant GCS change.

Correct Answer is B

Explanation

A. Increased systemic blood pressure – While systemic vasoconstriction may occur to maintain perfusion, it is a result of compensatory mechanisms like RAAS, not a primary mechanism leading to fluid retention and edema.

B. Renin-angiotensin-aldosterone activation – RAAS leads to:

Sodium and water retention via aldosterone

Vasoconstriction via angiotensin II

These changes increase intravascular volume, contributing to fluid overload and edema.

C. Ventricular hypertrophy – This is a structural adaptation to increased workload (pressure overload), not directly responsible for fluid retention.

D. Ventricular dilation – Dilation occurs as a result of chronic volume overload, not as a compensatory mechanism causing fluid retention.
