A nurse is reinforcing teaching with a client who is at 24 weeks of gestation and has opioid use disorder. Which of the following statements should the nurse make?

(A) Apply elastic stockings before the client gets out of bed:
While elastic stockings can help prevent thrombophlebitis by promoting venous return and reducing the risk of blood pooling in the legs, applying them before the client gets out of bed may not be as effective as ambulation in preventing stasis and clot formation.

(B) Have the client ambulate as often as possible:
Ambulation helps prevent thrombophlebitis (inflammation of a vein with clot formation) by promoting blood circulation in the lower extremities. Moving the legs and walking encourage the calf muscles to contract, which aids in pushing blood back towards the heart, reducing the risk of blood stasis and clot formation.

(C) Apply warm, moist packs to the client's lower legs:
Applying warm, moist packs to the lower legs may provide comfort and relaxation, but it is not a primary measure for preventing thrombophlebitis. In fact, warm compresses may dilate blood vessels and potentially increase the risk of thrombosis in some cases.

(D) Administer NSAIDs every 4 to 6 hr:
Nonsteroidal anti-inflammatory drugs (NSAIDs) are not typically used for preventing thrombophlebitis. While NSAIDs can help manage pain and inflammation, they do not directly address the underlying mechanisms of thrombus formation or prevent blood stasis. Additionally, frequent administration of NSAIDs may carry risks of gastrointestinal bleeding and renal complications.

(a) "You will not be able to eat or drink anything for 8 hours prior to the test."
There are no fasting requirements for a nonstress test. The client can eat and drink normally before the test. Nonstress tests do not require the same preparation as some other medical tests, such as fasting or dietary restrictions.

(b) "You will be required to lie flat on your back for the duration of the test."
Lying flat on the back can cause supine hypotension syndrome in pregnant women, which can lead to decreased blood flow to the fetus. Instead, clients are typically positioned in a semi-Fowler's or lateral position to avoid this issue.

(c) "You will receive medication through an IV line to stimulate contractions."
This describes a contraction stress test, not a nonstress test. A nonstress test involves monitoring the fetal heart rate in response to natural fetal movements without inducing contractions through medication.

(d) "You will press the provided button when you feel the baby moving during the test."
During a nonstress test, the client is instructed to press a button whenever they feel fetal movement. This helps the healthcare provider correlate fetal movements with changes in the fetal heart rate, which can indicate fetal well-being.
