A nurse is preparing to administer a 5 mg IV bolus of metoprolol to a patient for heart rate control.

The available metoprolol injection is 1 mg/mL. How many mL should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["5"]

Step 1 is: Calculate the volume of metoprolol to administer using the formula: Volume = Dose ÷ Concentration

Step 2 is: Substitute the given values into the formula: Volume = 5 mg ÷ 1 mg/mL

Step 3 is: Perform the calculation: Volume = 5 mL. So, the nurse should administer 5 mL of metoprolol per dose.

Correct Answer is {"dropdown-group-1":"E","dropdown-group-2":"B"}

Explanation

The condition that poses the greatest risk to the newborn is Meconium aspiration syndrome due to color of amniotic fluid.

Meconium aspiration syndrome is a serious condition that can occur when a newborn inhales a mixture of meconium (the first stool) and amniotic fluid into the lungs around the time of delivery. The dark brown-greenish color of the amniotic fluid indicates the presence of meconium, which increases the risk of this condition.

Correct Answer is B

Explanation

Choice A rationale

Lower quadrant pain is a common symptom of many conditions, including ectopic pregnancy. However, it does not specifically indicate the presence of blood in the peritoneum.

Choice B rationale

Cullen’s sign, which is the appearance of bruising in the skin around the umbilicus, is a sign of blood in the peritoneum. It can occur in conditions such as a ruptured ectopic pregnancy.

Choice C rationale

Goodell’s sign is a softening of the cervix that typically occurs early in pregnancy. It does not indicate the presence of blood in the peritoneum.

Choice D rationale

Chadwick’s sign is a bluish discoloration of the cervix, vagina, and labia that occurs in early pregnancy. It does not indicate the presence of blood in the peritoneum.
