The nurse is caring for different 4 clients. Which of the following client assessments would cause the most concern for the nurse?

Choice A reason: A negative fecal occult blood test suggests no gastrointestinal bleeding, reducing the urgency for a colonoscopy. Black stool can result from benign causes like iron supplements, so immediate invasive procedures are not warranted without further history or symptoms.

Choice B reason: Assuming a false negative without evidence is premature. Fecal occult blood tests are reliable for detecting bleeding. Black stool may stem from non-bleeding causes like medications or diet, and suggesting a false result could unnecessarily alarm the patient.

Choice C reason: Stress does not directly cause black stool. While stress can exacerbate gastrointestinal issues, black stool is more likely due to dietary factors, medications, or rare conditions. This question is vague and less relevant to the symptom’s likely etiology.

Choice D reason: Iron supplements commonly cause black stool due to the oxidation of iron in the gastrointestinal tract, a benign side effect. Given the negative fecal occult blood test, asking about iron supplements is the most appropriate, targeted response to identify a likely cause.

Choice A reason: Stopping the enema entirely is premature and unnecessary for cramping, which is a common response to rapid fluid instillation. Documentation of intolerance is only appropriate if the procedure cannot be completed after attempting adjustments. This action fails to address the cramping’s cause, potentially delaying constipation relief and patient comfort.

Choice B reason: Lowering the solution container reduces the flow rate of the enema, decreasing intraluminal pressure in the colon. Cramping often results from rapid fluid instillation stretching the bowel. Slowing the flow allows the colon to accommodate the fluid, alleviating discomfort while continuing the procedure effectively.

Choice C reason: Encouraging the client to bear down is inappropriate as it may cause premature expulsion of the enema fluid, reducing its effectiveness in relieving constipation. Bearing down increases intra-abdominal pressure, potentially exacerbating cramping rather than alleviating it, and does not address the underlying cause of discomfort from fluid instillation.

Choice D reason: Allowing the client to expel fluid prematurely interrupts the enema’s purpose of softening stool and stimulating bowel movement. While it may temporarily relieve cramping, it reduces the procedure’s efficacy, potentially requiring a repeat enema, which increases patient discomfort and procedural risks like rectal irritation.
