A nurse is reinforcing teaching with the partner of a client who has contact precautions in place for methicillin-resistant Staphylococcus aureus (MRSA).
Which of the following statements by the client's partner indicates an understanding of the teaching?

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.

This response indicates that the client understands that sudden jaw pain can be a sign of a heart attack and requires immediate medical attention.

A. "I will take four nitroglycerin sublingual tablets if I have chest pain." This is an incorrect statement because taking four nitroglycerin sublingual tablets can lead to hypotension and can be life-threatening.

B. "I will have hot, dry, and flushed skin if I am having a heart attack." This is an incorrect statement because hot, dry, and flushed skin is not a typical sign of a heart attack.

C. "I will wait 30 minutes before taking action if I have heartburn." This is an incorrect statement because heartburn is not a symptom of angina and waiting 30 minutes to take action can lead to further complications.

Explanation: The client with angina should be educated about the signs and symptoms of a heart attack and when to seek medical attention. Jaw pain is one of the signs of a heart attack, and the client should seek emergency medical attention immediately.
