A nurse is collecting data from a client who is taking an oral contraceptive. Which of the following findings is a contraindication for the use of oral contraceptives?

A. "Apply rubber-soled slippers before ambulation.": This is important for safety, but it is not the first step in fall prevention. The client needs to be able to call for assistance if needed before moving around.

B. "Determine the client's ability to use the call light.": This should be the first step. Ensuring that the client can easily use the call light in case they need help is a foundational fall prevention strategy. It is essential for maintaining the client’s safety and enabling them to request assistance when needed.

C. "Create a schedule with an assistive personnel to do hourly rounding for the client.": Hourly rounding is an important fall prevention measure, but it should follow initial steps such as ensuring the client can call for help. It can be implemented after determining how the client will communicate needs.

D. "Move the bedside table with the client's personal items close to the bed.": This is a helpful precaution, as it reduces the need for the client to reach or stand to access their belongings. However, the most critical initial step is ensuring the client can safely summon help if needed.

A. Respiratory acidosis is incorrect. Chronic diarrhea typically leads to metabolic acidosis, not respiratory acidosis. Metabolic acidosis occurs due to the loss of bicarbonate through diarrhea, which affects the body’s acid-base balance.

B. Hypermagnesemia is incorrect. Chronic diarrhea is more likely to lead to hypomagnesemia due to the loss of electrolytes through frequent bowel movements, not an increase in magnesium levels.

C. Hypertension is incorrect. Chronic diarrhea generally leads to dehydration and hypotension due to fluid loss rather than high blood pressure.

D. Hypokalemia is correct. Chronic diarrhea causes significant potassium loss, which can result in hypokalemia (low potassium levels). Potassium is lost in the stool, and this depletion can lead to muscle weakness, arrhythmias, and other complications.
