A nurse is assessing a client who is 8 hours postpartum.
Where should the nurse expect to find the fundus?

Choice A rationale

Pain in the abdomen, shoulder, or back can be associated with pre-term labor or other pregnancy complications and should be assessed. However, respiratory depression, hypotension, and absent tendon reflexes are more indicative of magnesium sulfate toxicity and pose an immediate threat to the client's safety.

Choice B rationale

Magnesium sulfate is a central nervous system depressant used to prevent seizures in pre-eclampsia and tocolysis in pre-term labor. Respiratory depression (respiratory rate less than 12 breaths per minute), hypotension (systolic blood pressure less than 90 mmHg or a significant drop from baseline), and absent deep tendon reflexes are signs of magnesium toxicity and require immediate intervention to prevent serious adverse effects.

Choice C rationale

Severe lower back pain, leg cramps, and sweating can be symptoms of pre-term labor or other musculoskeletal issues during pregnancy. While important to assess and manage, they do not represent the same immediate life-threatening risk as magnesium toxicity.

Choice D rationale

Low potassium or elevated glucose levels, tachycardia, and chest pain are not typical side effects of magnesium sulfate. These findings could indicate other underlying medical conditions that need investigation, but they are not the priority assessment related to magnesium sulfate administration compared to signs of toxicity. Normal potassium range is 3.5-5.0 mEq/L, normal fasting glucose is 70-100 mg/dL.

Choice A rationale

Increasing ambulation is generally encouraged in the postpartum period to prevent complications like thrombophlebitis, but it does not address the potential cause of foul-smelling lochia. Foul odor is a key indicator of infection, and ambulation will not resolve an existing infection.

Choice B rationale

Increasing oral fluids is important for hydration in the postpartum period, but it will not directly address a foul-smelling odor in the lochia. While adequate hydration supports overall healing, it does not treat an infection. A foul odor strongly suggests a localized infectious process in the uterus.

Choice C rationale

Lochia that is red (rubra) is normal in the first few days postpartum. However, a foul-smelling odor is an abnormal finding and a significant indicator of a potential uterine infection, also known as endometritis or puerperal infection. Further assessment and intervention are required to identify and treat the infection.

Choice D rationale

Normal lochia progresses from rubra (red) to serosa (pinkish-brown) to alba (yellowish-white) over several weeks postpartum. Normal lochia should have a fleshy, not foul, odor. A foul smell is an abnormal finding that suggests an infectious process within the uterus and requires prompt attention.
