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. What action should the nurse take when a child presents with fever, sore throat, swollen red spots, and fluid-filled blisters?

• A. Obtain a fluid culture from the blisters
• B. Administer a fever-reducing medication
• C. Cover the drainage vesicles with a dressing
• D. Implement transmission precautions

Correct answer: D

Rationale: When a child presents with fever, sore throat, swollen red spots, and fluid-filled blisters, it may indicate a contagious viral infection. In such cases, implementing transmission precautions is crucial to prevent the spread of the infection to others in the pediatric clinic or community. Obtaining a fluid culture from the blisters (Choice A) may not be necessary at the initial stage without knowing the cause of the infection. Administering a fever-reducing medication (Choice B) may help manage symptoms but doesn't address the need for preventing transmission. Covering the drainage vesicles with a dressing (Choice C) may provide comfort to the child but does not directly address the risk of transmission to others.

3. A 2-year-old child is admitted with severe dehydration due to gastroenteritis. Which assessment finding indicates that the child's condition is improving?

• A. Decreased heart rate.
• B. Sunken fontanelle.
• C. Increased urine output.
• D. Dry mucous membranes.

Correct answer: C

Rationale: Increased urine output is a positive sign indicating that the child's hydration status is improving. It suggests that the kidneys are functioning more effectively and able to excrete urine, which is a crucial indicator of improved hydration levels in a dehydrated patient. Decreased heart rate (Choice A) can be a sign of possible shock. A sunken fontanelle (Choice B) is a sign of dehydration. Dry mucous membranes (Choice D) are also indicative of dehydration.

4. A child with a fever of 39°C (102.2°F) and a sore throat is brought to the clinic. The practical nurse suspects the child has streptococcal pharyngitis. Which diagnostic test should the practical nurse prepare the child for?

• A. Rapid antigen detection test.
• B. Throat culture.
• C. Complete blood count (CBC).
• D. Chest X-ray.

Correct answer: A

Rationale: A rapid antigen detection test is the appropriate diagnostic test for suspected streptococcal pharyngitis. This test is commonly used due to its quick results, helping in the prompt diagnosis and appropriate treatment of the condition. It specifically detects the presence of streptococcal antigens in the throat, aiding in confirming the diagnosis and guiding the healthcare provider in determining the most suitable treatment plan. Throat culture (Choice B) is a confirmatory test but is not as rapid as the rapid antigen detection test. Complete blood count (Choice C) and Chest X-ray (Choice D) are not specific tests for streptococcal pharyngitis and would not aid in confirming the diagnosis.

5. What is the priority action for a 2-year-old child with croup presenting with a barking cough and stridor?

• A. Administer a corticosteroid
• B. Obtain a throat culture
• C. Administer nebulized epinephrine
• D. Place the child in an upright position

Correct answer: C

Rationale: The priority action for a 2-year-old child with croup and stridor is to administer nebulized epinephrine. Nebulized epinephrine helps reduce airway swelling, alleviate symptoms, and improve breathing by causing vasoconstriction and reducing upper airway edema. Administering a corticosteroid may be done but is not the priority in this scenario. Obtaining a throat culture is not necessary for the immediate management of croup. Placing the child in an upright position can aid in breathing but is not the priority action when the child is presenting with stridor.
