A nurse is preparing to administer nifedipine to a client who is in pre-term labor.
The nurse should withhold the medication and notify the provider if the client has which of the following conditions?
Asthma
Diabetes mellitus
Hypertension
Cardiac disease
The Correct Answer is D
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.

Correct Answer is A
Explanation
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that helps close the ductus arteriosus, a blood vessel connecting two arteries of the heart (aorta and pulmonary artery) in fetus.This drug is effective only among premature babies.
Choice B.Prostaglandin E1 is wrong because it is used to keep the ductus arteriosus open in some congenital heart defects that require surgery.
Choice C.Furosemide is wrong because it is a diuretic that reduces fluid retention and blood pressure, but does not affect the ductus arteriosus.
Choice D.Digoxin is wrong because it is a cardiac glycoside that strengthens the heart muscle contractions and regulates the heart rhythm, but does not affect the ductus arteriosus.
Correct Answer is D
Explanation
“I will call my doctor if I have more than four contractions in an hour.” This statement indicates that the client understands the signs of preterm labor and when to seek medical attention.Preterm labor is defined as having regular contractions and cervical changes before 37 weeks of gestation.More than four contractions in an hour may indicate that preterm labor is occurring and requires prompt evaluation.
Choice A is wrong because drinking at least eight glasses of water every day is not a specific instruction for preventing preterm labor.However, dehydration can trigger contractions and should be avoided.
Choice B is wrong because lying on the back with a pillow under the knees can reduce blood flow to the uterus and the baby.This position can also increase the risk of blood clots in the legs.A better position is lying on the left side, which improves circulation and reduces pressure on the cervix.
Choice C is wrong because avoiding sexual intercourse until reaching term is not necessary for most women with a history of preterm labor.Sexual activity does not cause preterm labor or premature rupture of membranes (PROM).However, some women may be advised to abstain from sex if they have certain conditions, such as placenta previa or a short cervix.
