Nursing Elites

1. The parents of a 3-year-old boy who has 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?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family.
• B. The male infant had a viral infection that went unnoticed and untreated, leading to muscle damage.
• C. The lack of the protein dystrophin in the mother can impact the muscle groups of males.
• D. Damage to the spinal cord due to birth trauma from a breech vaginal birth weakens the muscles.

Correct answer: A

Rationale: The nurse should inform the parents that Duchenne muscular dystrophy is an X-linked recessive disorder, which primarily affects male children in the family. This genetic condition is caused by a mutation in the dystrophin gene located on the X chromosome. Females are usually carriers of the gene mutation and may pass it on to their sons. Daughters of carrier mothers have a 50% chance of being carriers themselves. Understanding the genetics of DMD can help the parents make informed decisions about family planning and genetic counseling.

2. A 15-month-old child is brought to the clinic for a routine checkup. The nurse notes that the child is not walking independently yet. What should the nurse do next?

• A. Refer the child for a developmental assessment
• B. Encourage the parents to start physical therapy
• C. Reassure the parents that some children walk later than others
• D. Discuss the importance of early intervention services

Correct answer: C

Rationale: The correct answer is to reassure the parents that some children walk later than others. It is essential to understand that children reach developmental milestones at different ages. Walking independently can occur later in some children, and it is normal. Referring the child for a developmental assessment (Choice A) may cause unnecessary concern at this stage. Encouraging physical therapy (Choice B) or discussing early intervention services (Choice D) may not be warranted unless there are specific concerns identified during the checkup.

3. The nurse is caring for a 4-year-old child who is hospitalized with pneumonia. The child is receiving IV antibiotics and oxygen therapy. The nurse notes that the child’s respiratory rate is 40 breaths per minute, and the oxygen saturation is 92%. What is the nurse’s priority action?

• A. Increase the child’s oxygen flow rate
• B. Notify the healthcare provider
• C. Encourage the child to take deep breaths
• D. Auscultate the child’s lung sounds

Correct answer: D

Rationale: In this scenario, the child is hospitalized with pneumonia, receiving IV antibiotics and oxygen therapy. With a high respiratory rate and decreased oxygen saturation, auscultating the child’s lung sounds is the priority action. This assessment can provide crucial information about the child’s respiratory status, such as the presence of adventitious sounds or decreased air entry, which can guide further interventions and help in evaluating the effectiveness of the current treatments. Increasing the oxygen flow rate may not address the underlying issue causing the decreased oxygen saturation. Notifying the healthcare provider can be necessary but auscultating lung sounds should be done first to gather more information. Encouraging the child to take deep breaths is important for respiratory function but should not be the immediate priority in this situation.

4. A child receives a prescription for amantadine 42 mg PO BID. Amantadine is available as a 50 mg/5 mL syrup. Using a supplied calibrated measuring device, how many mL should be administered per dose? (Round to the nearest tenth.)

• A. 4.2 mL
• B. 5 mL
• C. 3.6 mL
• D. 4 mL

Correct answer: A

Rationale: To calculate the mL per dose, divide the prescribed dose (42 mg) by the concentration of the syrup (50 mg/5 mL) and then convert the result to mL. 42 mg / 50 mg = 0.84. To find the amount in mL, multiply 0.84 by 5 mL, which equals 4.2 mL. Therefore, 4.2 mL should be administered per dose.

5. A child with Graves' disease who is taking propranolol (Inderal) is seen in the clinic. The nurse should monitor the child for which therapeutic response?

• A. Increased weight gain
• B. Decreased heart rate
• C. Reduced headaches
• D. Diminished fatigue

Correct answer: B

Rationale: When a child with Graves' disease is prescribed propranolol (Inderal), the nurse should monitor for a decreased heart rate as a therapeutic response. Propranolol is a beta-blocker that acts to slow down the heart rate, which is beneficial in managing the symptoms of Graves' disease, such as tachycardia and other cardiovascular manifestations. Choices A, C, and D are incorrect because propranolol is not typically associated with increased weight gain, reduced headaches, or diminished fatigue as its primary therapeutic effect in this context.
