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.

All of the above.
Respiratory distress syndrome (RDS) is a condition that affects preterm newborns who have immature lungs and lack sufficient surfactant.
Surfactant is a substance that helps keep the alveoli open and prevents them from collapsing.
Without enough surfactant, the newborn has difficulty breathing and may develop hypoxia and acidosis.
Choice A is wrong because tachypnea and grunting are signs of respiratory distress, but they are not specific to RDS.
They can also be caused by other conditions such as transient tachypnea of the newborn, pneumonia, or congenital heart defects.
Choice B is wrong because bradycardia and cyanosis are also signs of respiratory distress, but they are not specific to RDS.
They can also be caused by other conditions such as hypothermia, hypoglycemia, or sepsis.
Choice C is wrong because apnea and nasal flaring are also signs of respiratory distress, but they are not specific to RDS.
They can also be caused by other conditions such as intracranial ...
Correct Answer is B
Explanation
Tachycardia.
Terbutaline is a medication that can be used to stop or delay preterm labor by relaxing the uterine muscles.However, it can also cause serious side effects for both the mother and the baby.One of the most common side effects of terbutaline is tachycardia, which means a fast or irregular heartbeat.This can lead to chest pain, palpitations, shortness of breath, and even cardiac arrhythmias or ischemia.
Therefore, the nurse should monitor the mother’s heart rate and rhythm closely when administering terbutaline.
Choice A is wrong because terbutaline does not cause hypotension, which means low blood pressure.In fact, terbutaline can increase blood pressure by constricting blood vessels.
Choice C is wrong because terbutaline does not cause hyperglycemia, which means high blood sugar.However, terbutaline can interfere with insulin secretion and glucose metabolism in some cases, especially in diabetic mothers.
Therefore, the nurse should monitor the mother’s blood sugar levels when administering terbutaline.
Choice D is wrong because terbutaline does not cause hypokalemia, which means low potassium levels in the blood.However, terbutaline can cause a temporary increase in potassium levels in the baby, which can affect the baby’s heart function.
Therefore, the nurse should monitor the baby’s heart rate and rhythm when administering terbutaline.
Normal ranges for heart rate are 60 to 100 beats per minute for adults and 120 to 160 beats per minute for fetuses.
Normal ranges for blood pressure aretypically between 90/60 mmHg and 120/80 mmHg.
