A nurse is caring for a term macrosomic newborn whose mother has poorly controlled type 2 diabetes. The newborn has respiratory distress syndrome. The nurse should be aware that the most likely cause of the respiratory distress is which of the following?

Increased risk of anemia

Hyperinsulinemia

Increased blood viscosity

Brachial plexus injury

Answer and Explanation

The Correct Answer is B

Choice A reason: Increased risk of anemia is not a likely cause of respiratory distress in a term macrosomic newborn, as it can affect any newborn regardless of the maternal diabetes status or the fetal size. Anemia can cause pallor, tachycardia, and poor feeding, but not respiratory distress.

Choice B reason: Hyperinsulinemia is a likely cause of respiratory distress in a term macrosomic newborn, as it results from the fetal exposure to high maternal glucose levels and the subsequent overproduction of insulin. Hyperinsulinemia can impair the synthesis of surfactant, which is a substance that prevents the alveoli from collapsing and facilitates gas exchange. Hyperinsulinemia can also cause hypoglycemia, which can affect the respiratory center and cause apnea.

Choice C reason: Increased blood viscosity is not a likely cause of respiratory distress in a term macrosomic newborn, as it can affect any newborn with polycythemia, which is an abnormally high number of red blood cells. Polycythemia can cause cyanosis, jaundice, and thrombosis, but not respiratory distress.

Choice D reason: Brachial plexus injury is not a likely cause of respiratory distress in a term macrosomic newborn, as it affects the nerves that supply the arm and hand, not the lungs. Brachial plexus injury can occur due to the excessive traction or stretching of the shoulder during delivery, and can cause weakness, paralysis, or sensory loss in the affected arm.

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. "It promotes fetal lung maturity." B. "It halts cervical dilation." C. "It increases the fetal heart rate." D. "It is used to stop preterm labor contractions."

Correct Answer is A

Explanation

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.
