What is a normal, age-related change in the gastrointestinal system of an older adult?

Choice A rationale

Cramping during an enema is often caused by the rapid distension of the intestinal walls or the temperature of the fluid, which triggers intestinal spasms. Temporarily stopping the flow for approximately 30 seconds allows the bowel to relax and the spasm to subside. Resuming the infusion at a slower rate or lower height reduces the pressure exerted on the bowel wall, which helps minimize further discomfort while ensuring the procedure is completed.

Choice B rationale

Encouraging the client to take slow, deep breaths can help with relaxation and may slightly reduce the perception of pain, but it does not address the physical cause of the cramping, which is the volume or speed of the fluid entering the colon. While useful as an adjunct, it is not the primary intervention. The nurse must first manage the flow of the solution to directly alleviate the mechanical source of the client's distress.

Choice C rationale

Withdrawing the tube by 2 centimeters is an intervention used if the tube is poorly positioned or if there is resistance to flow, but it is not the standard response to generalized cramping. Cramping is typically a reaction to the fluid volume and pressure rather than the depth of the rectal tube. Moving the tube could also lead to accidental removal or leakage of the solution, which would further complicate the cleansing process.

Choice D rationale

Telling the client that the process will not take much longer is a form of verbal reassurance, but it dismisses the client's immediate physical pain and does not provide a physiological solution to the cramping. Effective nursing care requires active intervention to relieve symptoms. Ignoring the discomfort by simply asking the client to endure it can lead to increased anxiety, higher heart rates, and a negative experience that may decrease future compliance.

Choice A rationale

While the collection bag itself has volume markings, they are notoriously inaccurate for precise medical monitoring. These markings are often printed on flexible plastic that distorts when filled, leading to significant errors in volume estimation. The bag is intended for containment and storage of urine rather than exact measurement. Relying on this method can lead to incorrect assessments of a client's renal perfusion and overall fluid balance status in clinical settings.

Choice B rationale

A graduated cylinder or urimeter is the gold standard for measuring urine output because these devices are specifically calibrated for high precision. A urimeter is a small, hard plastic chamber attached to the drainage bag that allows for hourly monitoring of small volumes. Accurate measurement is critical for identifying early signs of acute kidney injury or fluid volume deficit. Using a rigid, calibrated container ensures that the volume recorded reflects the actual output produced by the kidneys.

Choice C rationale

A standard specimen collection cup is primarily designed for obtaining a small sample of urine for laboratory analysis, such as a urinalysis or culture. These cups generally only hold 60 to 90 mL of fluid, which is insufficient for measuring total voided volume or shift output from an indwelling catheter. Using such a small container would require multiple transfers of urine, increasing the risk of spills and exposure to biohazardous materials for the healthcare provider and environment.

Choice D rationale

A bedside commode bucket is intended for clients who can sit upright but cannot walk to the bathroom. These buckets are large and often lack the fine graduation marks required for precise clinical measurement of urine output. Using a commode bucket for a client with an indwelling catheter is inappropriate because it introduces unnecessary steps and increases the risk of contamination. Accurate output requires a smaller, more precisely calibrated vessel to ensure fluid balance is monitored correctly.
