The nurse is administering subcutaneous enoxaparin to a client following knee replacement surgery to prevent a deep vein thrombosis. Which laboratory result requires immediate action by the nurse?

Reference Range:

Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)]

Platelets [150,000 to 400,000/mm (150 to 400 x 10L)

Creatinine (0.5 to 1.1 mg/dL (44 to 97 μmol/L)]

Blood Urea Nitrogen (BUN) [10 to 20 mg/dl (3.6 to 7.1 mmol/L)]

A) Tendon pain or swelling can be a sign of tendinitis or tendon rupture, which can be serious side effects of ciprofloxacin. Therefore, it is crucial for the client to report any tendon pain or swelling to the healthcare provider immediately.

B) Ciprofloxacin can increase sensitivity to sunlight, leading to an increased risk of sunburn. Therefore, clients should be advised to limit exposure to sunlight and avoid tanning beds while taking this medication.

C) Crushing or mixing ciprofloxacin tablets with pudding is not recommended, as it may alter the absorption and effectiveness of the medication. Clients should swallow the tablets whole with a full glass of water.

D) Increasing fluid intake while taking ciprofloxacin is generally recommended to prevent dehydration and help flush the medication through the kidneys. Adequate hydration can also help reduce the risk of crystalluria, a potential adverse effect of ciprofloxacin.

E) Using nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve joint aches and pains caused by ciprofloxacin is not recommended, as NSAIDs can increase the risk of tendon problems when used with ciprofloxacin. It is important for the client to report any joint aches or pains to the healthcare provider for proper evaluation and management.

The nurse should administer 0.8 mL of the enoxaparin sodium injection.

Here's th’ breakdown of the calculation:

Prescribed dose: 80 mg

Available medication: 60 mg/0.6 mL

The nurse needs to determine the volume of the available medication that delivers the prescribed dose of 80 mg. We can set up a proportion to find the desired volume (x):

Prescribed dose (mg) : Desired volume (mL) = Concentration (mg/mL) : Available volume (mL)

Plugging in the values:

80 mg : x mL = 60 mg/0.6 mL : 0.6 mL

To isolate x (desired volume), we can cross-multiply:

x mL x (60 mg/0.6 mL) = 80 mg x 0.6 mL

Simplifying the equation

0.6x mL = 48 mg

To find x (desired volume), we can divide both sides by 0.6 mL:

x mL = (48 mg) / (0.6 mL/mL) // Cancel out units (mg/mL)

x = 80 mL

However, the answer needs to be rounded to the nearest tenth since medication dosages are measured precisely.

Therefore, the nurse should administer 0.8 mL of the enoxaparin sodium injection.
