A nurse is admitting a client who is at 30 weeks of gestation and is in preterm labor. The client has a new order for betamethasone and asks the nurse about the purpose of this medication. The nurse should provide which of the following explanations?

"It promotes fetal lung maturity."

"It halts cervical dilation."

"It increases the fetal heart rate."

"It is used to stop preterm labor contractions."

Answer and Explanation

The Correct Answer is A

Choice A reason: This statement is correct, as betamethasone is a corticosteroid that is given to pregnant women who are at risk of delivering before 34 weeks of gestation. Betamethasone stimulates the production of surfactant, which is a substance that prevents the alveoli from collapsing and improves the lung function of the fetus.

Choice B reason: This statement is incorrect, as betamethasone does not affect the cervical dilation, which is a sign of labor progression. Betamethasone does not stop or delay labor, but rather reduces the complications of prematurity, such as respiratory distress syndrome, intraventricular hemorrhage, or necrotizing enterocolitis.

Choice C reason: This statement is incorrect, as betamethasone does not increase the fetal heart rate, which is a measure of fetal well-being. Betamethasone may cause transient fetal bradycardia, which is a decrease in the fetal heart rate, due to the increased vagal tone and blood pressure. The nurse should monitor the fetal heart rate and notify the provider if there are any signs of fetal distress.

Choice D reason: This statement is incorrect, as betamethasone is not used to stop preterm labor contractions, which are caused by the uterine muscle activity. Betamethasone does not have any tocolytic effect, which is the ability to inhibit uterine contractions. Other medications, such as magnesium sulfate, nifedipine, or indomethacin, may be used to stop preterm labor contractions.

Correct Answer is ["0.5"]

Explanation

To calculate the number of tablets, the nurse should use the following formula:

Number of tablets = (Desired dose / Available dose) x (Available form / Desired form)

In this case, the desired dose is 50 mg, the available dose is 100 mg, the available form is 1 tablet, and the desired form is 1 tablet. Therefore, the formula becomes:

Number of tablets = (50 mg / 100 mg) x (1 tablet / 1 tablet)

Number of tablets = 0.5 x 1

Number of tablets = 0.5

The nurse should round the answer to the nearest tenth, which is 0.5. The nurse should use a leading zero if the answer is less than 1, which is 0.5. The nurse should not use a trailing zero, which means 0.5 and not 0.50.

A. Continuous fetal monitoring B. Ambulate to induce labor C. Obtain a daily weight D. Assess deep tendon reflexes every hour

Correct Answer is B

Explanation

Choice A reason: This order does not require clarification, as it is an appropriate and standard order for a client who has severe preeclampsia, which is a hypertensive disorder of pregnancy that can cause fetal distress, growth restriction, or demise. Continuous fetal monitoring can help detect and evaluate the fetal heart rate, variability, accelerations, decelerations, and contractions, and guide the management and intervention.

Choice B reason: This order requires clarification, as it is an inappropriate and contraindicated order for a client who has severe preeclampsia, which is a hypertensive disorder of pregnancy that can cause seizures, stroke, or organ failure. Ambulation can increase the blood pressure, stimulate the labor, and worsen the condition. The client should be on bed rest, with the head of the bed elevated, and receive medications to lower the blood pressure and prevent seizures.

Choice C reason: This order does not require clarification, as it is an appropriate and standard order for a client who has severe preeclampsia, which is a hypertensive disorder of pregnancy that can cause edema, proteinuria, or oliguria. Obtaining a daily weight can help monitor the fluid status, the severity of the edema, and the response to the treatment.

Choice D reason: This order does not require clarification, as it is an appropriate and standard order for a client who has severe preeclampsia, which is a hypertensive disorder of pregnancy that can cause hyperreflexia, clonus, or seizures. Assessing deep tendon reflexes every hour can help evaluate the neuromuscular irritability, the risk of eclampsia, and the effect of magnesium sulfate.
