Nursing Elites

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. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

3. The healthcare provider is preparing to suture a 10-year-old with a lacerated forehead. Both parents and the 12-year-old sibling are at the child’s bedside. Which instruction best supports the family?

• A. While waiting for the healthcare provider, only one family member may stay with the child.
• B. All family members should leave while the healthcare provider sutures the child’s forehead.
• C. It is best if the sibling goes to the waiting room until the suturing is completed.
• D. Please decide among yourselves who will stay when the healthcare provider begins suturing.

Correct answer: D

Rationale: Choice D is the best instruction as it involves the family in the decision-making process, allowing them to choose who will stay with the child during the suturing procedure. This approach supports the family's comfort and participation in the child's care, promoting a sense of control and family-centered care. Choices A, B, and C do not promote family involvement and may lead to feelings of exclusion or lack of control among the family members.

4. In planning care for a client at 30-weeks gestation experiencing preterm labor, what maternal prescription is most important in preventing this fetus from developing respiratory syndrome?

• A. Betamethasone (Celestone) 12mg deep IM.
• B. Butorphanol 1mg IV push q2h PRN pain.
• C. Ampicillin 1g IV push q8h.
• D. Terbutaline (Brethine) 0.25mg subcutaneously q15 minutes x3.

Correct answer: A

Rationale: The administration of Betamethasone (Celestone) is crucial in cases of preterm labor to promote fetal lung maturation and reduce the risk of respiratory distress syndrome in the newborn. Betamethasone helps enhance the production of surfactant in the fetal lungs, improving their functionality and decreasing the likelihood of respiratory complications upon birth. Butorphanol is an analgesic and not indicated for preventing respiratory syndrome in preterm infants. Ampicillin is an antibiotic used for infection prevention and treatment, not for fetal lung maturation. Terbutaline is a tocolytic agent used to inhibit contractions, but it does not have a direct effect on fetal lung maturity.

5. The healthcare provider is assessing a 38-week gestation newborn infant immediately following a vaginal birth. Which assessment finding best indicates that the infant is transitioning well to extrauterine life?

• A. Positive Babinski reflex.
• B. Flexion of all four extremities.
• C. Heart rate of 220 beats/min.
• D. Cries vigorously when stimulated.

Correct answer: D

Rationale: A vigorous cry upon stimulation indicates that the newborn has good respiratory effort and is transitioning well to life outside the womb. It shows that the infant's airways are clear, and they are able to establish effective breathing, a crucial aspect of transitioning successfully to extrauterine life. Choices A, B, and C are not the best indicators of successful transition to extrauterine life. The Babinski reflex and flexion of extremities are normal neonatal reflexes and do not specifically indicate successful transition. A heart rate of 220 beats/min is abnormally high for a newborn and could indicate distress rather than a smooth transition.
