Correct Answer is C

Explanation

Choice A rationale

While increasing caloric intake can be beneficial for breastfeeding mothers, it does not directly address the client’s concern about decreased insulin needs.

Choice B rationale

Advising the client to breastfeed more frequently does not directly address the client’s concern about decreased insulin needs.

Choice C rationale

Breastfeeding can lead to a decreased need for insulin in some individuals. This is because lactation requires energy, and this energy demand can affect the mother’s insulin requirements.

Choice D rationale

While scheduling an appointment with the diabetic nurse educator can be helpful, it is not the immediate response to the client’s concern about decreased insulin needs.

A. Abruptio placenta. B. Chorioamnionitis. C. Round ligament strain. D. Viral infection.

Correct Answer is B

Explanation

Choice A rationale

Abruptio placenta is a condition where the placenta prematurely separates from the uterus. It typically presents with symptoms such as vaginal bleeding, back pain, and frequent contractions. However, the symptoms described by the client do not align with this condition.

Choice B rationale

Chorioamnionitis is an infection of the membranes surrounding the fetus and is associated with prolonged labor. Symptoms include fever, abdominal pain, and fetal tachycardia. The client’s symptoms of pain when the baby moves, a high temperature, and severe abdominal or uterine tenderness on palpation align with this condition.

Choice C rationale

Round ligament strain is a common cause of pain during pregnancy, particularly in the second trimester. It is caused by the stretching of the round ligaments that support the uterus.

However, it does not cause fever or severe abdominal tenderness.

Choice D rationale

While a viral infection could potentially cause a fever, it would not typically cause severe abdominal or uterine tenderness specifically when the baby moves.
