A nurse is reinforcing teaching with a client who will undergo a colonoscopy the following week. Which of the following instructions should the nurse include?
Restrict the diet to clear liquids for 1 to 3 days before the procedure.
Expect the provider to schedule another procedure to remove any polyps.
Do not eat or drink anything except water for 12 hours before the procedure.
Administer enemas 2 days before the procedure.
None
None
The Correct Answer is A
The correct answer is Choice A.
Choice A rationale: A clear liquid diet 1 to 3 days before a colonoscopy minimizes residue in the colon, enhancing mucosal visualization and reducing the risk of missed lesions. Clear liquids include water, broth, tea, and gelatin, which are easily absorbed and leave minimal waste. This dietary preparation complements bowel cleansing agents like polyethylene glycol. Inadequate preparation can obscure polyps or inflammation. Normal stool consistency should be absent during the procedure to ensure optimal diagnostic accuracy.
Choice B rationale: Polypectomy is typically performed during the colonoscopy itself if polyps are detected. Most polyps are removed using snares or biopsy forceps during the same session, reducing the need for a second procedure. Scheduling another procedure is reserved for complex or large lesions requiring advanced techniques. Delaying removal increases the risk of progression to malignancy. Normal colonoscopy findings include pink mucosa and absence of polyps; any deviation warrants immediate intervention when feasible.
Choice C rationale: Restricting intake to only water for 12 hours before the procedure is insufficient and potentially misleading. Colonoscopy preparation requires both dietary modification and pharmacologic bowel cleansing, not just fasting. Water alone does not clear the colon of fecal matter. Additionally, fasting without electrolyte replacement may lead to dehydration and electrolyte imbalance. Normal serum potassium ranges from 3.5 to 5.0 mEq/L; inadequate preparation may cause hypokalemia, especially with laxative use.
Choice D rationale: Enemas are not routinely recommended 2 days before colonoscopy. They may be used adjunctively on the day of the procedure for distal colon cleansing but are insufficient for full bowel preparation. Oral bowel prep agents like polyethylene glycol are preferred for complete evacuation. Enemas only reach the rectosigmoid region and do not cleanse the ascending or transverse colon. Incomplete prep compromises mucosal visualization and diagnostic yield, increasing false-negative rates.

Correct Answer is B
Explanation
The client takes ibuprofen for headaches. NSAIDs such as ibuprofen can cause gastrointestinal bleeding, which can result in a false positive result on a fecal occult blood test.
Option A is incorrect because breast cancer is not associated with false-positive fecal occult blood results.
Option C is incorrect because citrus juice does not affect the fecal occult blood test.
Option D is incorrect because a hemorrhoidectomy is not associated with false-positive fecal occult blood results.
Reasons why the other options are not answered:
Option A: Breast cancer is not associated with false-positive fecal occult blood results.
Option C: Citrus juice does not affect the fecal occult blood test.
Option D: A hemorrhoidectomy is not associated with false-positive fecal occult blood results.
Correct Answer is D
Explanation
The correct answer is: D.
Choice A reason: Asking a patient to rate their pain on a scale from 0 to 10 is a common method to assess the intensity of pain, not the quality. Zero indicates no pain, and ten represents the most severe pain imaginable. This scale is quantitative and helps in tracking the effectiveness of pain management over time.
Choice B reason: Inquiring if the pain is the same as it has been is a question that assesses the consistency or changes in the patient’s pain over time. It does not provide information about the quality of the pain but rather its course or any variations in the experience of pain.
Choice C reason: Asking whether the patient has any pain this morning is a question that determines the presence or absence of pain at a particular time. It does not elicit details about the nature or characteristics of the pain, which are essential to understanding its quality.
Choice D reason: Asking “What does your pain feel like?” is a qualitative question that aims to describe the characteristics of the pain, such as aching, stabbing, or burning. This information is crucial for diagnosing the cause of pain and tailoring appropriate treatment strategies. It directly addresses the quality of the pain, which is the focus of the nurse’s inquiry.
