1. 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.
2. 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.
3. A woman at 36-weeks' gestation who is Rh negative is admitted to labor and delivery reporting abdominal cramping. She is placed on strict bedrest, and the fetal heart rate and contraction pattern are monitored with an external fetal monitor. The nurse notes a large amount of bright red vaginal bleeding. Which nursing intervention has the highest priority?
- A. Perform a sterile vaginal examination to determine dilatation.
- B. Determine fetal position by performing Leopold maneuvers.
- C. Assess the fetal heart rate and client's contraction pattern.
- D. Confirm Rh and Coombs status for Rho(D) immunoglobulin administration.
Correct answer: C
Rationale: The highest priority nursing intervention in this scenario is to assess the fetal heart rate and the client's contraction pattern. The presence of a large amount of bright red vaginal bleeding in a woman at 36-weeks' gestation who is Rh negative raises concerns about the well-being of the fetus. Monitoring the fetal heart rate and contraction pattern will provide crucial information about fetal status and help determine the appropriate course of action to ensure the safety and health of both the mother and the baby.
4. A client with no prenatal care arrives at the labor unit screaming, 'The baby is coming!' The nurse performs a vaginal examination that reveals the cervix is 3 centimeters dilated and 75% effaced. What additional information is most important for the LPN/LVN to obtain?
- A. Gravidity and parity.
- B. Time and amount of last oral intake.
- C. Date of last normal menstrual period.
- D. Frequency and intensity of contractions.
Correct answer: C
Rationale: Obtaining the date of the last normal menstrual period is crucial in estimating the gestational age of the fetus. This information helps in determining the progression of labor and the management of delivery. It also assists healthcare providers in assessing the overall health of the mother and the fetus. Choices A, B, and D are important in labor assessment, but in this scenario, the most crucial information needed is the date of the last normal menstrual period to estimate the gestational age.
5. During the newborn admission assessment, the nurse palpates the newborn's scrotum and does not feel the testicles. Which assessment technique should the nurse perform next to verify the absence of testes?
- A. Observe the urethral opening on the surface of the penis when the newborn voids.
- B. Perform transillumination of the scrotal sac to visualize shadows of the testes.
- C. Use a fingertip to palpate the inguinal canal for a retractile or undescended testis.
- D. Measure the size of the scrotal sac for length and width.
Correct answer: C
Rationale: If the testes are not palpated in the scrotum, the next step is to check the inguinal canal for a retractile or undescended testis. This technique allows the nurse to determine if the testes are located within the inguinal canal rather than the scrotum. It is essential to assess for the presence of testes in the inguinal canal to ensure proper diagnosis and management of any potential issues related to testicular positioning.
