The nurse is administering SUBQ 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/mm3 (150 to 400 x 10^9/L)]
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)]
Platelet count of 100,000/mm3 (100 x 10^9/L).
Serum creatinine 1.0 mg/dL (88.4 μmol/L).
Blood urea nitrogen (BUN) 20 mg/dL (7.1 mmol/L).
Hematocrit 45% (0.45 volume fraction).
The Correct Answer is A
A. A platelet count of 100,000/mm3 indicates thrombocytopenia, which increases the risk of bleeding with enoxaparin and requires immediate action.
B. A serum creatinine level of 1.0 mg/dL is within the normal range and does not require immediate action.
C. A BUN level of 20 mg/dL is at the upper end of the normal range but does not typically require immediate action unless accompanied by other symptoms.
D. A hematocrit level of 45% is within the normal range and does not require immediate action.

Explanation
1. Peripheral edema: Non-therapeutic side effect
- Mannitol is an osmotic diuretic that can cause fluid shifts leading to peripheral edema, which is an unintended side effect.
2. Potassium 2.9: Non-therapeutic side effect
- Hypokalemia (low potassium) is a potential side effect of mannitol due to increased urinary excretion of electrolytes.
3. Urine output 280 mL: Therapeutic result
- Mannitol increases urine output as it promotes diuresis, which is the intended therapeutic effect.
4. Heart rate 79: Unrelated finding
- The heart rate of 79 beats/minute is within normal limits and is not directly related to the administration of mannitol.
5. Intracranial pressure 11 mmHg: Therapeutic result
- The decrease in intracranial pressure from 24 mmHg to 11 mmHg is a desired therapeutic outcome of mannitol, as it helps reduce cerebral edema.
6. Oxygen saturation: Unrelated finding
- The oxygen saturation of 99% is within normal limits and is not directly related to the administration of mannitol.
Correct Answer is A
Explanation
A. Sucralfate should be taken on an empty stomach, at least 1 hour before meals, to be effective in coating and protecting the gastrointestinal mucosa.
B. Taking sucralfate up to 1 hour after a meal may reduce its effectiveness in coating the stomach lining.
C. Documenting refusal is not appropriate if the medication can be taken later as long as it meets the timing requirements.
D. Sucralfate should not be taken with food as it needs to be administered on an empty stomach to be effective.
