A nurse is caring for a client who has hyperemesis gravidarum.
Which of the following laboratory tests should the nurse anticipate?

Rationale for Correct Condition

Subinvolution refers to delayed uterine involution, often due to retained placental fragments or infection. The boggy uterus, excessive lochia, and passage of clots are hallmark signs. The history of postpartum hemorrhage increases risk, and fundal tenderness suggests uterine atony rather than infection or hematoma formation.

Rationale for Correct Actions

Oxytocin enhances uterine contractions to reduce bleeding and facilitate involution by increasing myometrial tone. Methylergonovine is a potent uterotonic that further supports contraction, decreasing hemorrhage risk, but must be used cautiously in hypertensive patients.

Rationale for Correct Parameters

Saturated perineal pads track blood loss severity, guiding interventions for ongoing hemorrhage. Excessive bleeding may require further medical management. Hemoglobin and hematocrit assess for anemia due to blood loss, guiding transfusion decisions if needed.

Rationale for Incorrect Conditions

Postpartum preeclampsia presents with hypertension and proteinuria, not uterine atony. Perineal hematoma manifests as localized swelling with severe perineal pain, which is absent here. Thrombophlebitis involves unilateral extremity swelling and pain, not fundal tenderness or abnormal lochia.

Rationale for Incorrect Actions

Ice packs to the perineum manage hematomas, not uterine atony. Anticoagulants are used for thromboembolic prevention, not postpartum bleeding. Quiet environment is relevant for preeclampsia, not uterine subinvolution.

Rationale for Incorrect Parameters

Seizures are relevant to preeclampsia, not uterine subinvolution. Calf circumference is monitored for thrombophlebitis, which is absent here. Rectal pain is not an expected indicator of uterine involution status.

Choice A rationale

Hyperemesis gravidarum is severe nausea and vomiting during pregnancy, typically occurring in the first trimester. While amniocentesis can cause some discomfort, it is not a known risk factor for hyperemesis.

Choice B rationale

Proteinuria is the presence of protein in the urine, which can be a sign of preeclampsia, a condition that can occur later in pregnancy. Amniocentesis, usually performed in the second trimester, is not directly linked to causing proteinuria.

Choice C rationale

Amniocentesis is an invasive procedure that involves inserting a needle through the abdominal wall and uterus to withdraw amniotic fluid. This procedure carries a risk of bleeding or hemorrhage from the insertion site or within the uterus. Therefore, observing for signs of hemorrhage is a crucial nursing intervention post-amniocentesis.

Choice D rationale

Hypoxia is a condition of insufficient oxygen supply to the tissues. While complications of amniocentesis could indirectly lead to fetal hypoxia in rare cases (e.g., placental abruption), it is not a direct and common complication to observe for in the mother. Hemorrhage is a more immediate and direct risk for the mother. .
