1. The parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) ask, 'How can our son have this disease? We are wondering if we should have any more children.' What information should the nurse provide these parents?

Correct answer: A

Rationale: The correct answer is A. Duchenne muscular dystrophy is an X-linked recessive disorder, meaning the gene mutation causing DMD is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if the X chromosome they inherit from their mother carries the mutated gene, they will develop DMD. Females have two X chromosomes, so they are carriers of the gene but are usually not affected by the disease. Therefore, the nurse should explain to the parents that DMD is an inherited X-linked recessive disorder that primarily affects male children in the family.

2. The nurse instructs a laboring client to use accelerated-blow breathing. The client begins to complain of tingling fingers and dizziness. What action should the nurse take?

Correct answer: C

Rationale: Tingling fingers and dizziness are symptoms of hyperventilation, which can occur with accelerated-blow breathing. Instructing the client to breathe into her cupped hands can help rebreathe exhaled carbon dioxide, which can alleviate the symptoms by restoring the proper balance of oxygen and carbon dioxide in the blood. This intervention can be effective in managing the client's hyperventilation without the need for additional medical interventions at this point.

3. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperneic. Which action should the nurse implement first?

Correct answer: A

Rationale: In a tetralogy of Fallot situation, placing the infant in a knee-chest position is the initial priority to help increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation. This position can assist in optimizing oxygen levels before considering other interventions. Administering morphine sulfate (choice B) is not the first-line treatment for tetralogy of Fallot crisis. Starting intravenous fluids (choice C) may be necessary but is not the priority in this situation. Providing 100% oxygen by face mask (choice D) may not fully address the underlying issue of decreased systemic vascular resistance that leads to cyanosis in tetralogy of Fallot.

4. When assessing a client who is at 12-weeks gestation, the LPN/LVN recommends that she and her husband consider attending childbirth preparation classes. When is the best time for the couple to attend these classes?

Correct answer: D

Rationale: The best time for the couple to attend childbirth preparation classes is around 30 weeks gestation, which is during the third trimester. Attending classes at this time allows the couple to learn essential information and skills as labor and delivery are approaching, maximizing the benefit of the classes. Option A is too early in the second trimester, and the couple might forget important details by the time labor approaches. Option B is also early in the second trimester, and attending later allows for better preparation. Option C is still in the second trimester, and waiting until the third trimester provides more practical knowledge closer to delivery.

5. Assessment findings of a 4-hour-old newborn include: axillary temperature of 96.8°F (35.8°C), heart rate of 150 beats/minute with a soft murmur, irregular respiratory rate at 64 breaths/minute, jitteriness, hypotonia, and weak cry. Based on these findings, which action should the nurse implement?

Correct answer: B

Rationale: The assessment findings in the newborn, such as jitteriness, weak cry, and hypotonia, are indicative of potential hypoglycemia. To confirm this suspicion, the nurse should obtain a heel stick blood glucose level, which is the most appropriate action in this situation. Checking the blood glucose level will provide crucial information to determine the newborn's glucose status and guide further management if hypoglycemia is confirmed. Swaddling the infant in a warm blanket does not address the underlying issue of potential hypoglycemia and may not effectively raise the blood glucose level. Placing a pulse oximeter on the heel is not indicated for assessing hypoglycemia. Documenting the findings in the record is important but does not address the immediate concern of assessing and managing potential hypoglycemia.
