Nursing Elites

1. What information should the nurse provide to parents of a 3-year-old boy with Duchenne muscular dystrophy who inquire about the disease and future children?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family
• B. The striated muscle groups of males can be impacted by a lack of the protein dystrophin in their mothers
• C. The male infant had a viral infection that went unnoticed and untreated so muscle damage was incurred
• D. Birth trauma with a breech vaginal birth causes damage to the spinal cord, thus weakening the muscles

Correct answer: A

Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons. Choice B is incorrect as it inaccurately implies that the lack of dystrophin in mothers impacts their sons' muscle groups. Choice C is incorrect as it suggests a viral infection caused the muscle damage, which is not the case with Duchenne muscular dystrophy. Choice D is incorrect as it attributes the muscle weakness to birth trauma instead of the genetic nature of the disorder.

2. The healthcare provider is preparing to administer digoxin (Lanoxin) to a 6-month-old infant with heart failure. The healthcare provider notes that the infant’s heart rate is 90 beats per minute. What should the healthcare provider do next?

• A. Administer the medication as prescribed
• B. Hold the medication and notify the healthcare provider
• C. Reassess the heart rate in 30 minutes
• D. Administer half the prescribed dose

Correct answer: B

Rationale: In this scenario, the correct action is to hold the medication and notify the healthcare provider. Digoxin should be withheld if the infant’s heart rate is below 100 beats per minute. Administering digoxin in this situation can further slow down the heart rate in infants with heart failure, leading to potential adverse effects. Reassessing the heart rate in 30 minutes is not the best immediate action to take, as prompt notification and withholding of the medication are crucial. Administering the medication as prescribed or giving half the dose can exacerbate the situation by potentially further lowering the heart rate.

3. A child who weighs 25 kg is receiving IV ampicillin 300 mg/kg/24 hours in equally divided doses every 4 hours. How many milligrams should the nurse administer to the child for each dose?

• A. 1875 mg
• B. 625 mg
• C. 2000 mg
• D. 1500 mg

Correct answer: A

Rationale: To calculate the dose for each administration, multiply the child's weight (25 kg) by the dose (300 mg/kg/24 hours) and divide by the number of doses per day (6, as doses are every 4 hours). This gives us (25 kg * 300 mg/kg / 24 hours) / 6 doses = 1875 mg. Therefore, the nurse should administer 1875 mg for each dose. Choice B, 625 mg, is incorrect as it does not consider the correct calculation based on the weight and prescribed dose. Choice C, 2000 mg, is incorrect as it is not derived from the correct dosage calculation. Choice D, 1500 mg, is incorrect as it does not reflect the accurate dosage calculation based on the weight of the child and the prescribed dose.

4. The healthcare provider is preparing to administer a scheduled dose of digoxin to a 4-year-old child with heart failure. The healthcare provider notes that the child’s heart rate is 70 beats per minute. What should the healthcare provider do next?

• A. Administer the medication as prescribed
• B. Hold the medication and notify the healthcare provider
• C. Recheck the heart rate in 30 minutes
• D. Administer half of the prescribed dose

Correct answer: B

Rationale: In pediatric patients, digoxin administration is guided by the heart rate. If the child's heart rate is below the established threshold, which is typically 90-100 beats per minute in a 4-year-old, the medication should be withheld, and the healthcare provider should be notified for further evaluation and instructions. Choice A is incorrect because administering the medication when the heart rate is low can lead to adverse effects. Rechecking the heart rate in 30 minutes (Choice C) may delay necessary intervention if the heart rate remains low. Administering half of the prescribed dose (Choice D) is not recommended without healthcare provider guidance.

5. An adolescent's mother calls the primary HCP's office to inquire about the results of her daughter's serum test that was drawn last week. Since it is the teenager's 18th birthday, how should the nurse respond to this mother's inquiry?

• A. Ask when the adolescent was last seen at the clinic
• B. Tell the mother to have the teenager call the clinic
• C. Provide the mother with the findings
• D. Explain that the information cannot be released without the 18-year-old's permission

Correct answer: D

Rationale: The correct response is to explain to the mother that the information cannot be released without the 18-year-old's permission. When an individual turns 18, they are legally considered an adult, and privacy laws mandate that their consent is required before sharing their medical information with others. It is crucial to respect the adolescent's autonomy and privacy rights. Choices A and C are incorrect because they involve disclosing the information without the individual's consent. Choice B is incorrect as it does not address the legal requirement for the adolescent's permission before sharing medical information.
