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) Tell the client to apply hydrocortisone ointment to the affected area of the breast:
Hydrocortisone ointment is not appropriate for treating mastitis, which is an infection of the breast tissue. The primary treatments for mastitis include antibiotics, pain management, and supportive measures like warm compresses to relieve discomfort and promote milk flow.

(B) Suggest the client apply warm compresses to the affected breast:
Applying warm compresses to the affected breast can help relieve pain and promote milk flow, which can aid in resolving the infection. Warmth can help reduce inflammation and make breastfeeding or pumping less painful.

(C) Recommend the client avoid wearing a nursing bra until symptoms resolve:
Avoiding a nursing bra is not necessary. In fact, wearing a well-fitting and supportive nursing bra can help manage discomfort and support the breasts. It is important that the bra is not too tight to avoid further compression and blockage of milk ducts.

(D) Encourage the client to limit oral fluid intake to decrease milk production:
Limiting fluid intake is not recommended. Adequate hydration is important for overall health and maintaining milk supply. Reducing fluid intake does not effectively manage mastitis and can lead to dehydration.

(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.
