Nursing Elites

1. A healthcare professional is preparing to administer magnesium sulfate 2 g/hr IV to a client who is in preterm labor. Available is 20 g of magnesium sulfate in 500 mL of dextrose 5% in water (D5W). How many mL/hr should the IV infusion pump be set to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 60
• B. 30
• C. 50
• D. 80

Correct answer: C

Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.

2. A client who is at 36 weeks of gestation and has a prescription for a nonstress test is being taught by a nurse. Which of the following statements should the nurse include in the teaching?

• A. You will receive IV fluid before this test.
• B. The procedure will take approximately 10 to 15 minutes.
• C. You will be offered orange juice to drink during the test.
• D. You will need to sign an informed consent form before each test.

Correct answer: C

Rationale: The correct statement the nurse should include in the teaching is that the client will be offered orange juice to drink during the nonstress test. This is because offering the client orange juice, or another beverage high in glucose, will help stimulate the fetus during the procedure, aiding in obtaining accurate results. Choice A is incorrect because IV fluid is not typically administered before a nonstress test. Choice B is incorrect as the procedure usually takes around 20 to 40 minutes. Choice D is incorrect as informed consent is typically obtained once for the procedure, not before each individual test.

3. A client presents with uterine hypotonicity and postpartum hemorrhage. Which action should the nurse prioritize?

• A. Check the client's capillary refill.
• B. Massage the client's fundus.
• C. Insert an indwelling urinary catheter for the client.
• D. Prepare the client for a blood transfusion.

Correct answer: B

Rationale: In a client with uterine hypotonicity and postpartum hemorrhage, the priority is to address the risk of hypovolemic shock, which can lead to vital organ perfusion compromise and potentially death. Massaging the client's fundus helps to control bleeding by promoting uterine contraction and reducing blood loss, making it the nurse's priority intervention in this situation. Checking capillary refill may be important in assessing perfusion status but is not the priority over controlling the hemorrhage. Inserting an indwelling urinary catheter is not the priority in managing postpartum hemorrhage. Although preparing for a blood transfusion may be necessary, addressing the primary cause of bleeding by massaging the fundus takes precedence to stabilize the client's condition.

4. A client gave birth 2 hours ago, and their blood pressure is 60/50 mm Hg. What action should the nurse take first?

• A. Evaluate the firmness of the uterus.
• B. Initiate oxygen therapy via a non-rebreather mask.
• C. Administer oxytocin infusion.
• D. Obtain a type and crossmatch.

Correct answer: A

Rationale: Assessing the firmness of the uterus is crucial in this situation. A uterus that is not firm could indicate postpartum hemorrhage, a common cause of low blood pressure after childbirth. By evaluating the firmness of the uterus, the nurse can quickly identify and address potential complications, such as excessive bleeding. Initiating oxygen therapy, administering oxytocin infusion, or obtaining a type and crossmatch may be necessary interventions later, but assessing the firmness of the uterus takes precedence as the first step in managing postpartum complications.

5. A client in a prenatal clinic is pregnant and experiencing episodes of maternal hypotension. The client asks the nurse what causes these episodes. Which of the following responses should the nurse make?

• A. This is due to an increase in blood volume.
• B. This is due to pressure from the uterus on the diaphragm.
• C. This is due to the weight of the uterus on the vena cava.
• D. This is due to increased cardiac output.

Correct answer: C

Rationale: Maternal hypotension during pregnancy is often caused by the weight of the uterus pressing on the vena cava when the client is lying on her back, which reduces blood flow to the heart. This compression can lead to a decrease in blood pressure and subsequent symptoms of hypotension. Choice A is incorrect because an increase in blood volume typically leads to increased blood pressure rather than hypotension. Choice B is incorrect as pressure from the uterus on the diaphragm is not a common cause of maternal hypotension. Choice D is incorrect because increased cardiac output would not directly cause maternal hypotension.
