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?
Do not eat or drink anything except water for 12 hr before the procedure.
Restrict the diet to clear liquids for 1 to 3 days before the procedure.
Administer enemas 2 days before the procedure.
Expect the provider to schedule another procedure to remove any polyps.
The Correct Answer is B
Choice A rationale
Drinking water is allowed before the procedure, but all other food and drinks should be avoided.
Choice B rationale
A clear liquid diet for 1 to 3 days before the procedure helps to clear the intestines and ensure visibility during the colonoscopy.
Choice C rationale
Administering enemas 2 days before the procedure is not recommended. The focus is on dietary restrictions and prescribed laxatives.
Choice D rationale
The removal of polyps can often be done during the same colonoscopy procedure, avoiding the need for a separate procedure.

Correct Answer is C
Explanation
Choice A rationale
The flu shot provides protection for about one year. It is recommended to receive the flu shot annually for continued protection, especially as flu strains can vary each year.
Choice B rationale
The hepatitis B vaccine does not require annual administration. It is typically given in a series of shots over a few months and provides long-term protection.
Choice C rationale
Performing a breast self-exam a week after each menstrual period is ideal because hormonal changes that cause breast tissue to be tender or lumpy will be minimal, making it easier to detect any unusual changes.
Choice D rationale
Testicular self-exams are recommended to be done monthly, not every 6 months. Regular monthly exams help in early detection of any changes or abnormalities.
Correct Answer is A
Explanation
Choice A rationale
Kussmaul respirations are deep, labored breathing patterns associated with metabolic acidosis, commonly seen in severe hyperglycemia and diabetic ketoacidosis.
Choice B rationale
Diaphoresis, or sweating, is typically associated with hypoglycemia rather than hyperglycemia. Hyperglycemia often leads to dehydration and dry skin.
Choice C rationale
Urinary ketones are typically present in cases of severe hyperglycemia and diabetic ketoacidosis. Absence of urinary ketones does not indicate hyperglycemia.
Choice D rationale
Chvostek's sign, a twitching of facial muscles, is indicative of hypocalcemia rather than hyperglycemia. It is not a reliable indicator of high blood sugar levels.
