A nurse is reviewing the medical record of a client who is at 37 weeks of gestation and has HELLP syndrome. Which of the following laboratory findings should the nurse expect?
BUN 20 mg/dL
Platelet count 77,000/mm3
Hemoglobin 12 g/dL
WBC count 18,000/mm3
The Correct Answer is B
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.

Correct Answer is D
Explanation
A. Respiratory acidosis is incorrect. Chronic diarrhea typically leads to metabolic acidosis, not respiratory acidosis. Metabolic acidosis occurs due to the loss of bicarbonate through diarrhea, which affects the body’s acid-base balance.
B. Hypermagnesemia is incorrect. Chronic diarrhea is more likely to lead to hypomagnesemia due to the loss of electrolytes through frequent bowel movements, not an increase in magnesium levels.
C. Hypertension is incorrect. Chronic diarrhea generally leads to dehydration and hypotension due to fluid loss rather than high blood pressure.
D. Hypokalemia is correct. Chronic diarrhea causes significant potassium loss, which can result in hypokalemia (low potassium levels). Potassium is lost in the stool, and this depletion can lead to muscle weakness, arrhythmias, and other complications.
Correct Answer is D
Explanation
A. "Once my health care proxy is in place, I relinquish my right to make my own decisions" is incorrect. A health care proxy only comes into effect when the individual becomes incapacitated and unable to make decisions. Until then, the client retains the right to make their own decisions.
B. "My health care proxy designee is not able to sign a consent form on my behalf" is incorrect. The health care proxy designee is authorized to make decisions about medical treatment, which includes signing consent forms on the client’s behalf if the client is unable to do so.
C. "If I have a health care proxy, then I do not need to have a living will" is incorrect. A living will and a health care proxy are separate documents. A living will specify a person’s wishes regarding medical treatments in case they are unable to communicate, while a health care proxy designates someone to make decisions on their behalf. Both can be used together.
D. "I do not need to name a relative as my designee in my health care proxy" is correct. The designee does not have to be a relative. The client can choose anyone they trust to make healthcare decisions on their behalf when they are unable to do so.
