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
A white blood cell count of 12,000/mm3 indicates an infection that can trigger pre-term labor.The normal range for white blood cell count in pregnancy is 5.7-15.0×10 9 /L, which is equivalent to 5,700-15,000/mm3.
A count above this range suggests an inflammatory response to an infection.
Choice B is wrong because a hemoglobin level of 11 g/dL is within the normal range for pregnancy, which is 10-14 g/dL.
Choice C is wrong because a platelet count of 250,000/mm3 is within the normal range for pregnancy, which is 150,000-400,000/mm3.
Choice D is wrong because a blood glucose level of 90 mg/dL is within the normal range for pregnancy, which is 70-110 mg/dL.
Correct Answer is C
Explanation
True labor contractions cause cervical dilation and effacement.
This means that the cervix opens up and thins out to prepare for the baby’s passage through the birth canal.
Cervical changes can be measured by a pelvic exam.
Choice A is wrong because true labor contractions are regular and do not subside with rest.False labor contractions are irregular and may stop when you change position or activity level.
Choice B is wrong because false labor contractions are usually felt in the front of the abdomen, not in the lower back.True labor contractions may start in the back and radiate to the abdomen.
Choice D is wrong because false labor contractions do not increase in intensity with ambulation.True labor contractions may become stronger and closer together when you walk.
Normal ranges for cervical dilation and effacement vary depending on the stage of labor, but generally, full dilation is 10 cm and full effacement is 100%.
