A nurse is preparing to administer enoxaparin 0.75 mg/kg subcutaneously to a client who weighs 154 lb. The amount available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer?(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.).

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:
Wearing gloves when changing the cat's litter box is essential during chemotherapy because some chemotherapy drugs can be excreted in bodily fluids, including feces. Protecting against direct contact with potentially harmful substances is crucial to minimize exposure risks.
Choice B rationale:
Taking the temperature once each week is not a relevant precaution during chemotherapy. Monitoring temperature is important, but it should be done more frequently, such as daily, as chemotherapy can cause immunosuppression, increasing the risk of infection.
Choice C rationale:
Being able to attend a concert is not related to precautions during chemotherapy. It is essential for clients undergoing chemotherapy to avoid large gatherings and events where they might be exposed to infections.
Choice D rationale:
Allowing the toothbrush to dry completely between each use is a good hygiene practice but not specifically related to chemotherapy precautions. Proper oral hygiene is essential during chemotherapy, but using a soft toothbrush and regularly replacing it are more relevant considerations.
