1. 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.

2. Why is complete bedrest necessary for a pregnant client with mitral stenosis Class III?

• A. Complete bedrest decreases oxygen needs and demands on the heart muscle tissue.
• B. We want your baby to be healthy, and this is the only way we can ensure that will happen.
• C. I know you're upset. Would you like to talk about some activities you could do while in bed?
• D. Labor is difficult, and you need to use this time to rest before assuming child-caring duties.

Correct answer: A

Rationale: Complete bedrest is necessary for a pregnant client with mitral stenosis Class III to reduce the workload on the heart, lower oxygen consumption, and prevent complications associated with cardiac conditions like mitral stenosis. By remaining in bed, the client can help maintain cardiac function and promote a safer pregnancy outcome. Choice B is incorrect as it does not provide a specific reason related to the client's medical condition. Choice C is not addressing the medical necessity of bedrest for this particular client. Choice D is irrelevant and does not explain the importance of bedrest for a pregnant client with mitral stenosis Class III.

3. Twenty minutes after a continuous epidural anesthetic is administered, a laboring client's blood pressure drops from 120/80 to 90/60. What action should the healthcare provider take?

• A. Notify the healthcare provider or anesthesiologist immediately.
• B. Continue to assess the blood pressure every 5 minutes.
• C. Place the woman in a lateral position.
• D. Turn off the continuous epidural.

Correct answer: C

Rationale: Placing the woman in a lateral position is the appropriate action to improve venous return and cardiac output, helping to stabilize the blood pressure. This position can alleviate pressure on the inferior vena cava, reducing the risk of hypotension associated with epidural anesthesia. Turning off the continuous epidural would not be the initial action as it may not be necessary and could lead to inadequate pain relief for the client. Notifying the healthcare provider or anesthesiologist immediately is premature and should be done after attempting non-invasive interventions. Continuing to assess the blood pressure every 5 minutes is important, but placing the woman in a lateral position should be the first intervention to address the hypotension.

4. Upon arrival in the nursery, a newborn infant is breathing satisfactorily but appears dusky. What action should the LPN/LVN take first?

• A. Notify the healthcare provider immediately.
• B. Suction the infant's nares, then the oral cavity.
• C. Check the infant's oxygen saturation rate.
• D. Position the infant on the right side.

Correct answer: C

Rationale: The priority action in this scenario is to check the infant's oxygen saturation rate. This will provide crucial information on the infant's oxygen levels and the need for immediate oxygen therapy. Assessing oxygen saturation is essential in determining the severity of hypoxia and guiding further interventions to ensure adequate oxygenation. Option A is not the priority as immediate intervention related to oxygenation is needed before notifying the healthcare provider. Suctioning (Option B) may be necessary but should come after assessing oxygen saturation. Positioning the infant (Option D) does not address the immediate need to evaluate oxygen levels.

5. The healthcare provider prescribes oxytocin 2 milliunits/minute to induce labor for a client at 41-weeks gestation. The nurse initiates an infusion of Ringer’s Lactate solution 1000 mL with oxytocin 10 units. How many mL/hour should the nurse program the infusion pump?

• A. 12 mL/hour
• B. 2 mL/hour
• C. 22 mL/hour
• D. 42 mL/hour

Correct answer: A

Rationale: To calculate the infusion rate in mL/hour, first, convert 2 milliunits/minute to milliunits/hour by multiplying by 60 to get 120 milliunits/hour. Then, calculate the mL/hour using the formula: milliunits/hour (120) × total volume (1000 mL) ÷ units in IV solution (10 units) = 1200 mL/hour. Therefore, the nurse should program the infusion pump to deliver 12 mL/hour to provide the prescribed dose of oxytocin. Choice B is incorrect as it does not reflect the correct calculation. Choice C is incorrect as it is not derived from the correct formula. Choice D is incorrect as it is not the result of the accurate calculation based on the provided information.
