A nurse is assisting with the admission of a client who has hyperemesis gravidarum. Which of the following laboratory tests is the priority to complete?

(A) Increased fundal height:
Hyperemesis gravidarum, severe nausea, and vomiting during pregnancy, typically does not cause an increased fundal height. Fundal height may be normal or even decreased due to dehydration and weight loss.

(B) Poor skin turgor:
Poor skin turgor is a common finding in clients with hyperemesis gravidarum due to dehydration. Excessive vomiting leads to fluid loss and dehydration, resulting in poor skin elasticity and turgor.

(C) Decreased pulse rate:
Hyperemesis gravidarum usually results in dehydration and hypovolemia, which can lead to an increased heart rate rather than a decreased pulse rate. The body compensates for decreased fluid volume by increasing the heart rate to maintain adequate circulation.

(D) Proteinuria:
Proteinuria, the presence of abnormal amounts of protein in the urine, is not typically associated with hyperemesis gravidarum. Proteinuria can be a sign of kidney dysfunction or other medical conditions but is not directly related to severe nausea and vomiting during pregnancy.

(A) Urination urgency and frequency:
Increased urgency and frequency of urination are common discomforts during the first trimester of pregnancy. This occurs due to hormonal changes and the growing uterus pressing on the bladder, which reduces its capacity.

(B) Tingling in the fingers:
Tingling in the fingers, also known as carpal tunnel syndrome, is more commonly associated with the later stages of pregnancy when fluid retention is more pronounced. It is not typically a common discomfort during the first trimester.

(C) Round ligament pain:
Round ligament pain is more common in the second trimester when the uterus is growing rapidly and the ligaments supporting it stretch. This type of pain usually manifests as sharp, shooting pain in the lower abdomen or groin.

(D) Perineal discomfort and pressure:
Perineal discomfort and pressure are more common in the later stages of pregnancy, particularly in the third trimester, as the baby descends into the pelvis and prepares for birth. It is not typically a discomfort experienced during the first trimester.
