Which nursing intervention should be implemented first to promote urination? ## 보기 1. Insert an indwelling urinary catheter immediately 2. Assist the client to a normal voiding position **✔ 정답** 3. Administer prescribed diuretic medication 4. Perform intermittent catheterization **정답: 2** ## 해설 Assisting to a normal voiding position is the priority as it uses gravity and anatomy to promote natural urination non-invasively. Invasive measures like catheterization should be reserved if this fails. ## 심화 해설 Understanding the Priority Intervention for Urinary Retention The correct initial nursing action is to assist the client to a normal voiding position. This intervention is rooted in the foundational nursing principle of using the least invasive methods first. Before considering any pharmacological or invasive mechanical intervention, the nurse must optimize the client’s natural ability to void. The rationale is both physiological and psychological: the normal sitting or squatting position relaxes the pelvic floor muscles and leverages gravity, while also providing privacy and comfort, which are essential for the micturition reflex to occur effectively. Why Other Options Are Not the First Step The other options represent escalating levels of invasiveness and carry inherent risks that make them inappropriate as first-line interventions. - Inserting an indwelling urinary catheter immediately or performing intermittent catheterization are invasive procedures that breach the body’s primary defense against urinary tract infection. As highlighted in the meta-analysis protocol by Wang et al., postoperative urinary retention often leads to catheterization, which itself is an outcome the clinical team tries to avoid due to risks of infection and urethral trauma [2]. These should only be implemented after non-invasive strategies have failed. - Administering prescribed diuretic medication is incorrect as a first step because it does not address the underlying cause of retention, which is often functional or obstructive. Increasing urine production with a diuretic when the bladder is already unable to empty effectively can dangerously worsen bladder distension and cause patient discomfort, a concern echoed in the study on postpartum urinary retention where bladder overdistension is identified as a key mechanism leading to long-term voiding dysfunction [1]. Connecting the Evidence to Clinical Practice The study by Gu et al. on postpartum urinary retention (PUR) provides a clear clinical parallel. It identifies that PUR is not merely a discomfort but a condition that can progress to bladder overdistension and long-term voiding dysfunction [1]. The research emphasizes the importance of early identification and management of high-risk individuals, which in practice begins with basic, supportive nursing care. The nurse’s role is to first create an environment conducive to voiding—this includes positioning, providing privacy, and running water—before moving to predictive models or invasive rescue interventions. The systematic review protocol by Wang et al. further reinforces that simple, nurse-led, non-invasive approaches, such as suprapubic temperature stimulation, are being rigorously investigated precisely because the goal is to reduce the need for catheterization [2]. This underscores the hierarchy of interventions: always start with the simplest, safest, non-invasive technique to promote natural voiding.References (research sources) - [1]Postpartum Urinary Retention in Vaginal Delivery Women Under Epidural Analgesia: Risk Factors and Nursing Strategies.Research articleGu S, Shen H, Shen H.

(2026) · DOI: 10.1136/bmjopen-2026-118750 ## 임상 시나리오 Clinical Scenario A 68-year-old male client is admitted to the medical-surgical unit following a total hip arthroplasty performed under spinal anesthesia. Six hours post-procedure, the client reports suprapubic discomfort and a strong urge to void but has been unable to urinate. A bladder scan reveals 450 mL of urine. The client is currently lying supine in bed. Vital signs are stable. Nursing Considerations - **Privacy and Environment:** Ensure the room door is closed, curtains are drawn, and the environment is quiet to reduce psychological inhibition of the voiding reflex. - **Positioning:** Assist the client to a seated position on the bedside commode or use a fracture pan while elevating the head of the bed to a high Fowler’s position. For male clients, standing may be permitted if safety allows. This utilizes gravity and relaxes the perineal muscles. - **Sensory Stimulation:** Run warm water over the perineum or provide a warm sitz bath to promote muscle relaxation. The sound of running water can also trigger the micturition reflex. - **Pain Management:** Assess and address incisional pain, as pain can cause reflexive sphincter constriction and inhibit voiding. - **Fluid Balance:** Review the intake and output record to ensure adequate hydration, but avoid rapid fluid loading if the client is already distended. Escalation Protocol If non-invasive measures fail after 30–60 minutes and the bladder scan volume remains high (>400 mL) or the client develops increasing discomfort, proceed to intermittent catheterization as per the provider’s order. Indwelling catheterization is reserved for cases of persistent retention or when intermittent catheterization is contraindicated. Strict aseptic technique is mandatory during any catheterization to prevent CAUTI. ## 핵심 개념 - **Urinary Retention** — The inability to voluntarily empty the bladder completely, which can be acute or chronic and requires prompt assessment to prevent bladder distension and infection. - **Micturition Reflex** — The physiological process of urination involving the coordinated relaxation of the urethral sphincter and contraction of the detrusor muscle, facilitated by a relaxed environment and normal positioning. - **CAUTI** — Catheter-Associated Urinary Tract Infection, a common and preventable hospital-acquired infection resulting from the introduction of bacteria during catheter insertion or prolonged use. - **Least Invasive Principle** — A nursing guideline prioritizing non-invasive, conservative interventions such as repositioning and providing privacy before escalating to mechanical or pharmacological treatments. ## 같은 주제 문제 - [A nurse is caring for a client with chronic constipation.
