Explanation

The primary conservative management for small renal calculi (typically less than 5 mm) is to promote their spontaneous passage.
Increasing fluid intake to 2-3 liters per day increases urine volume and flow, creating a 'flushing' effect that helps move the stones through the urinary tract.
Ambulation and general physical activity utilize gravity and body movement to facilitate the downward descent of the stones from the kidney and through the ureter.
This combination of hydration and movement is the most effective non-invasive method a patient can use to expel small stones.

Option A: While straining all urine is a vital nursing instruction for a patient with renal calculi, its purpose is diagnostic—to retrieve the stone for analysis. It is not a therapeutic action that helps the stone to pass.
Option C: Bed rest is contraindicated for patients with small renal calculi. Immobility promotes urinary stasis, which can impede stone passage and increase the risk of urinary tract infections and further stone formation.
Option D: This option is vague. While pain management with analgesics (like NSAIDs) is a critical part of care for renal colic, 'medication to relax' is not the primary instruction for passing the stone. The focus is on expelling the calculus, with pain relief as a supportive measure.

Clinical Relevance

Nursing practice connection: Use the key finding related to Nursing management of renal calculi (kidney stones) to guide bedside assessment, documentation, and the next nursing action.
Patient education is a core nursing responsibility in managing nephrolithiasis. Clear instructions on fluid intake, activity, diet, and urine straining empower the patient to participate in their care and prevent recurrence.
Nurses must teach patients to recognize and report 'red flag' symptoms immediately, such as fever, chills, uncontrolled pain, or anuria (no urine output). These can indicate a serious complication like infection or complete urinary obstruction.
What if? If the patient had a large, obstructing stone (e.g., greater than 7 mm) with signs of infection, the priority would shift from conservative management to preparing the patient for an urgent intervention like ureteroscopy or percutaneous nephrolithotomy to relieve the obstruction.

How to Approach the Question

First, identify the key clinical information in the stem: the patient has 'multiple small renal calculi'. The word 'small' is critical, as it points towards conservative, non-invasive management.
Next, analyze the question's core task: what should the nurse 'instruct' the patient to do? This asks for a patient action to manage the condition.
Evaluate each option's role in managing small kidney stones. Does the action help expel the stone, monitor the condition, or manage symptoms?
Compare the options. Increasing fluids and ambulating are direct therapeutic actions to help pass the stone. Straining urine is for monitoring/diagnosis. Bed rest is counterproductive. Medication is for symptom relief.
Conclude that the most important instruction aimed at resolving the underlying problem (passing the stones) is to take plenty of fluids and ambulate.
