A nurse is assessing a client's understanding of a surgical procedure prior to witnessing their signature on the informed consent form. The nurse determines that the client does not understand what the procedure will involve. Which of the following actions should the nurse take?

Choice A rationale:

A decrease in NG tube drainage indicates that the client's stomach contents are not being aspirated excessively, which suggests that the IV fluids are effectively maintaining fluid volume balance. This finding is positive because it shows that the client is retaining the fluids they need, and it may also indicate improved gastrointestinal function and decreased risk of dehydration.

Choice B rationale:

The potassium level of 3.3 mEq/L (milliequivalents per liter) is low. The normal range for potassium is typically between 3.5 to 5.0 mEq/L. Hypokalemia (low potassium) can result from various factors and may cause muscle weakness, cardiac arrhythmias, and other complications. It is not a finding that indicates the effectiveness of fluid volume balance therapy.

Choice C rationale:

An increased heart rate may suggest that the client is experiencing fluid volume deficit or other physiological stress. It is not a finding that indicates the effectiveness of fluid volume balance therapy.

Choice D rationale:

A hematocrit level of 46% is within the normal range for adult males (typically around 38.8% to 50%) and indicates the proportion of red blood cells in the blood. While it can provide information about blood viscosity and hydration status, it does not directly indicate the effectiveness of fluid volume balance therapy.

Choice A rationale:

The nurse should not advise the client with multiple sclerosis to schedule all physical activities for the morning hours. While some individuals with multiple sclerosis may experience increased fatigue later in the day, the best approach is to encourage the client to schedule activities at times when they feel the most energetic and to balance physical activity with rest throughout the day.

Choice B rationale:

Monitoring blood pressure is essential while taking fingolimod, a medication used to treat multiple sclerosis, as it can cause a transient decrease in heart rate and blood pressure.

Therefore, the nurse should include this statement in the teaching to ensure the client's safety and early detection of any issues.

Choice C rationale:

This is the correct statement to include in the teaching. Clients with multiple sclerosis should avoid rigorous activities that increase body temperature, as this can worsen their symptoms due to the sensitivity of demyelinated nerves to heat. Activities such as hot baths or engaging in strenuous exercise in hot weather should be avoided.

Choice D rationale:

Corticosteroids are not typically used as a long-term treatment for multiple sclerosis. Instead, they are used for short courses during exacerbations to reduce inflammation and manage acute symptoms. Long-term use of corticosteroids can lead to significant adverse effects, so the nurse should not include this statement in the teaching.
