A nurse is caring for a client who has a deep vein thrombosis and a prescription for heparin. For which of the following findings should the nurse withhold the medication and notify the provider?

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:
A warm left leg is a normal finding and does not require immediate intervention. Warmth indicates adequate circulation to the limb.
Choice B rationale:
A pedal pulse strength of 2 in the left leg indicates diminished pulse but does not require immediate intervention. The nurse should continue to monitor the pulse and report any significant changes to the healthcare provider.
Choice C rationale:
The client's report of pain in the foot of the left leg is an expected finding due to the fractured left femur. Pain is a subjective symptom, and the nurse should address the client's pain appropriately but not intervene immediately based on this finding.
Choice D rationale:
This is the correct choice. A capillary refill time of 3 seconds in the left foot suggests impaired circulation, which could be indicative of compartment syndrome or other circulation-related issues. The nurse should intervene immediately by notifying the healthcare provider to prevent further complications.
