A nurse is admitting a client who is at 30 weeks of gestation and has pre-term labor.

Which of the following medications should the nurse anticipate administering to prevent fetal respiratory distress syndrome?

Betamethasone

Magnesium sulfate

Nifedipine

Indomethacin

Answer and Explanation

The Correct Answer is A

Betamethasone is a corticosteroid that is given to pregnant women who are at risk of preterm delivery to enhance fetal lung maturity and prevent respiratory distress syndrome. It is usually given in two doses, 24 hours apart, and takes effect within 24 hours of administration.

Choice B. Magnesium sulfate is wrong because it is used to prevent seizures in women with severe preeclampsia or eclampsia, not to prevent respiratory distress syndrome.

Choice C. Nifedipine is wrong because it is a calcium channel blocker that is used to inhibit uterine contractions and prolong pregnancy in women with preterm labor, not to prevent respiratory distress syndrome.

Choice D. Indomethacin is wrong because it is a nonsteroidal anti-inflammatory drug that is used to inhibit prostaglandin synthesis and reduce uterine activity in women with preterm labor, not to prevent respiratory distress syndrome. However, it can also cause premature closure of the ductus arteriosus in the fetus and should be avoided after 32 weeks of gestation.

Normal ranges for gestational age are 37 to 42 weeks.

Preterm labor is defined as regular uterine contractions with cervical changes.

Correct Answer is B

Explanation

Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that can cause renal impairment and elevated serum creatinine levels in both the mother and the fetus.This can lead to oligohydramnios, reduced fetal urine output, and fetal renal failure.

Therefore, the nurse should monitor the serum creatinine levels of the client and the fetus as a potential complication of indomethacin.

Choice A is wrong because indomethacin does not affect the platelet count.It may increase the risk of bleeding due to its antiplatelet effect, but it does not cause thrombocytopenia.

Choice C is wrong because indomethacin does not cause anemia or decrease the hematocrit.It may cause gastrointestinal bleeding or ulceration, which could lead to anemia, but this is not a common or direct effect of the medication.

Choice D is wrong because indomethacin does not cause hyperkalemia or increase the serum potassium levels.It may cause hyponatremia due to its effect on renal sodium excretion, but it does not affect potassium balance.

A. Asthma B. Diabetes mellitus C. Hypertension D. Cardiac disease

Correct Answer is D

Explanation

Nifedipine is a calcium channel blocker that is used to relax uterine contractions and postpone preterm labor.However, it can also lower blood pressure and cause side effects such as headache, dizziness, flushing, and palpitations.Therefore, it should be avoided in clients who have cardiac disease or other conditions that affect the heart function.

Choice A is wrong because asthma is not a contraindication for nifedipine.Nifedipine does not affect the airways or cause bronchospasm.

Choice B is wrong because diabetes mellitus is not a contraindication for nifedipine.Nifedipine does not affect blood glucose levels or insulin secretion.

Choice C is wrong because hypertension is not a contraindication for nifedipine.In fact, nifedipine can be used to treat high blood pressure as well as preterm labor.However, blood pressure should be monitored closely during nifedipine therapy to avoid hypotension.
