A CGRN is witnessing a patient's signature on a consent form for a colonoscopy. The patient states, "I'm not really sure what a polypectomy is, but the doctor said I should just sign this." What is the CGRN's most appropriate action?
Answer: B. Notify the gastroenterologist that the patient requires further explanation before signing.
The nurse's role in the informed consent process is to act as a patient advocate and witness, which includes verifying the patient's understanding. If the patient expresses confusion or a lack of understanding, it is the nurse's professional and ethical duty to pause the process and notify the physician. The physician who is performing the procedure is responsible for providing the primary explanation of the procedure, its risks, benefits, and alternatives to ensure the consent is truly informed.
An 85-year-old patient with mild dementia is scheduled for an EGD. The healthcare proxy (the patient's son) has signed the consent. In the pre-procedure area, the patient becomes agitated and repeatedly states, "I don't want this, leave me alone." Which action by the CGRN best demonstrates patient advocacy?
Answer: B. Pause the pre-procedure process and immediately notify the gastroenterologist of the patient's refusal.
Patient advocacy requires the nurse to protect the patient's rights and dignity. Even when a legal proxy has given consent, the patient's expressed refusal at the time of the procedure must be taken seriously. The most ethical action is to halt the process and inform the physician. Proceeding against the patient's active and repeated refusal could be considered battery. The physician must then reassess the situation with the healthcare proxy.
A CGRN is preparing a 70-year-old patient with a history of Stage 4 chronic kidney disease and congestive heart failure for a colonoscopy. Which type of bowel preparation regimen is absolutely contraindicated for this patient due to the risk of acute phosphate nephropathy and severe electrolyte shifts?
Answer: D. An oral sodium phosphate (OSP) based solution.
Oral sodium phosphate (OSP) preparations are absolutely contraindicated in patients with moderate to severe chronic kidney disease (Stage 3-5), heart failure, or liver disease. They can cause significant fluid shifts and electrolyte disturbances, including hyperphosphatemia, which can lead to acute phosphate nephropathy and worsening renal failure. Polyethylene glycol (PEG) based solutions are the safest alternative as they are iso-osmotic and not absorbed systemically.
A patient's spouse, who is not listed on any HIPAA release forms, approaches the CGRN in the recovery area and asks for the results of the colonoscopy. The patient is awake but still drowsy from sedation. What is the nurse's most ethical and legally compliant response?
Answer: D. Ask the patient directly, in the spouse's presence, for verbal permission to discuss the results.
According to HIPAA, the nurse must protect the patient's private health information. The most appropriate, patient-centered action is to empower the patient to make the decision. By asking the patient, even if drowsy, for verbal permission to share information, the nurse upholds the principles of patient autonomy and confidentiality. This directly involves the patient in the decision-making process regarding their own protected health information (PHI).
