A nurse is collecting data from a client who is taking an oral contraceptive. Which of the following findings is a contraindication for the use of oral contraceptives?

A. BUN 20 mg/dL: This is not specific to HELLP syndrome. A BUN level of 20 mg/dL is within the normal range and does not indicate the presence of HELLP syndrome, which is associated with liver dysfunction and low platelet count.

B. Platelet count 77,000/mm3: This is correct. HELLP syndrome (Hemolysis, Elevated Liver enzymes, and Low Platelets) is characterized by a low platelet count, often less than 100,000/mm3, which is a critical indicator of this condition.

C. Hemoglobin 12 g/dL: This is a normal hemoglobin level and is not typically associated with HELLP syndrome, where hemolysis (destruction of red blood cells) can cause anemia, which would lower hemoglobin levels.

D. WBC count 18,000/mm3: While an elevated WBC count can indicate infection or inflammation, it is not specifically associated with HELLP syndrome. The hallmark features of HELLP syndrome are low platelets and liver enzyme elevation, not elevated WBC.

A. "You can take a stool softener to prevent constipation." is correct. After a retinal detachment repair, clients should avoid straining during bowel movements, as increased intracranial pressure could affect the healing eye. Taking a stool softener is a helpful preventive measure to avoid constipation.

B. "You can remove your eye patch during the day." is incorrect. The eye patch should typically be worn continuously to protect the eye and support healing. The surgeon's specific instructions should be followed regarding when the patch can be removed.

C. "You should bend from the waist to pick up objects." is incorrect. After retinal surgery, clients should avoid bending from the waist as this can increase intraocular pressure, potentially compromising the surgical repair. Instead, clients should use proper body mechanics and bend at the knees.

D. "You can apply a warm, moist compress to your forehead to reduce pain." is incorrect. Applying a warm compress to the forehead is not typically recommended following a retinal repair. Clients should follow the specific post-operative instructions from the surgeon, which may include cold compresses or other methods of managing discomfort.
