A nurse is caring for several clients who are at risk of developing a pressure injury. Which of the following clients is most at risk?

Choice A rationale:
Is not suitable for a client who has undergone a mastectomy with axillary lymph node dissection. This exercise may put a strain on the surgical site and cause discomfort or injury.
Choice B rationale:
Is also not appropriate for a postoperative mastectomy client. It involves using the left hand extensively, which could potentially disrupt the healing process and cause pain.
Choice C rationale:
Is not recommended for a postoperative mastectomy client. It involves significant upper body movement, which may not be well-tolerated after surgery, especially with lymph node dissection.
Choice D rationale:
This exercise is suitable for a postoperative mastectomy client as it helps in maintaining hand and arm mobility without putting excessive strain on the surgical site. It also aids in preventing complications like lymphedema, which is a potential concern after lymph node dissection.

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.
