Nursing Elites

1. The client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?

• A. Betamethasone (Celestone).
• B. Magnesium sulfate.
• C. Terbutaline (Brethine).
• D. Ampicillin.

Correct answer: A

Rationale: Betamethasone (Celestone) is the medication of choice to promote fetal lung maturity in cases of preterm labor. It helps accelerate surfactant production in the fetal lungs, reducing the risk of respiratory distress syndrome. Administering betamethasone to the mother can improve the baby's lung function and overall outcome if preterm birth occurs. Magnesium sulfate is commonly used to prevent seizures in preeclampsia or eclampsia. Terbutaline is a tocolytic agent used to suppress preterm labor contractions. Ampicillin is an antibiotic used for various bacterial infections but does not promote fetal lung maturity.

2. A postpartum client who is Rh-negative refuses to receive RhoGAM after the delivery of an infant who is Rh-positive. Which information should the nurse provide this client?

• A. RhoGAM prevents maternal antibody formation for future Rh-positive babies.
• B. RhoGAM is not necessary unless all of her pregnancies are Rh-positive.
• C. The Rh-positive factor from the fetus threatens her blood cells.
• D. The mother should receive RhoGAM when the baby is Rh-negative.

Correct answer: A

Rationale: The correct answer is A. RhoGAM is administered to Rh-negative individuals after exposure to Rh-positive blood to prevent the development of antibodies that could harm future Rh-positive babies during subsequent pregnancies. By refusing RhoGAM after the delivery of an Rh-positive infant, the mother risks developing these antibodies, which could lead to hemolytic disease in future pregnancies with Rh-positive babies. Therefore, it is crucial for the nurse to explain to the client that receiving RhoGAM prevents the formation of maternal antibodies against Rh-positive blood, safeguarding the health of future babies. Choices B, C, and D are incorrect. Choice B is incorrect because RhoGAM is necessary after exposure to Rh-positive blood, regardless of the Rh status of future pregnancies. Choice C is incorrect as it does not accurately convey the purpose of RhoGAM administration. Choice D is incorrect because RhoGAM is specifically given after exposure to Rh-positive blood, not when the baby is Rh-negative.

3. A loading dose of terbutaline (Brethine) 250 mcg IV is prescribed for a client in preterm labor. Brethine 20 mg is added to 1,000 mL of D5W. How many milliliters of the solution should the nurse administer?

• A. 45
• B. 15 mL
• C. 4
• D. 13

Correct answer: D

Rationale: To calculate the amount of terbutaline to administer, first convert the dose to the same unit. 250 mcg = 0.25 mg. Next, set up a proportion: 20 mg is to 1000 mL as 0.25 mg is to X mL. Cross multiply and solve for X: 20 × X = 0.25 × 1000. X = (0.25 × 1000) / 20 = 12.5 mL. Therefore, the nurse should administer 13 mL of the solution. Choice A is incorrect as it does not reflect the correct calculation. Choice B is incorrect as it does not consider the accurate conversion and calculation. Choice C is incorrect as it is not the result of the correct proportion calculation.

4. A breastfeeding infant, screened for congenital hypothyroidism, is found to have low levels of thyroxine (T4) and high levels of thyroid-stimulating hormone (TSH). What is the best explanation for this finding?

• A. The thyroxine level is low because the TSH level is high.
• B. High thyroxine levels do not normally occur in breastfeeding infants.
• C. The thyroid gland does not produce normal levels of thyroxine for several weeks after birth.
• D. The TSH is high because of the low production of T4 by the thyroid.

Correct answer: D

Rationale: High TSH and low T4 levels indicate that the thyroid gland is not producing enough hormones, which is a sign of congenital hypothyroidism. In this case, the high TSH is a compensatory response by the body to stimulate the thyroid to produce more T4. Choice A is incorrect because TSH does not directly affect T4 levels; rather, it is the other way around where low T4 levels lead to high TSH levels. Choice B is incorrect because high thyroxine levels are not expected in congenital hypothyroidism. Choice C is incorrect as the thyroid gland should be producing normal levels of thyroxine shortly after birth, making this explanation unlikely in the context of congenital hypothyroidism.

5. The nurse is caring for a postpartum client who is exhibiting symptoms of a spinal headache 24 hours following the delivery of a normal newborn. Prior to the anesthesiologist's arrival on the unit, which action should the nurse perform?

• A. Apply an abdominal binder.
• B. Cleanse the spinal injection site.
• C. Insert an indwelling Foley catheter.
• D. Place procedure equipment at the bedside.

Correct answer: A

Rationale: In a postpartum client exhibiting symptoms of a spinal headache, applying an abdominal binder is a priority action. The abdominal binder can help reduce the severity of a spinal headache by increasing intra-abdominal pressure, which may relieve pressure on the dural sac and alleviate symptoms. This intervention can be performed promptly by the nurse to provide immediate relief while waiting for further evaluation and management by the anesthesiologist. Cleansing the spinal injection site (Choice B) is not the priority in this situation as the headache is likely due to a dural puncture during epidural anesthesia rather than infection. Inserting an indwelling Foley catheter (Choice C) and placing procedure equipment at the bedside (Choice D) are not the appropriate actions to address a spinal headache and should not take precedence over applying an abdominal binder.
