Nursing Elites

1. What information should the nurse provide the parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) who are concerned about having more children?

• 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 mother's lack of the protein dystrophin can impact the XXXX muscle groups in males.
• D. Birth trauma during a breech vaginal birth can damage the spinal cord, resulting in muscle weakness.

Correct answer: A

Rationale: The correct answer is A. Duchenne muscular dystrophy is an inherited X-linked recessive disorder that primarily affects male children in the family. Since it is X-linked, sons inherit the mutation from their mothers who are carriers of the abnormal gene. Therefore, the nurse should explain to the parents that any future sons they have would have a 50% chance of inheriting the mutation and having DMD, while daughters would have a 50% chance of being carriers like the mother.

2. An adolescent female who is leaning forward with her hands on her knees to breathe tells the practical nurse that she has been using triamcinolone (Azmacort) inhalation aerosol before coming to the clinic. Which action should the PN implement?

• A. Obtain vital signs and assess breath sounds for wheezing.
• B. Collect a blood sample for white blood cell count.
• C. Give the client a nebulizer breathing treatment.
• D. Administer another dose of Azmacort.

Correct answer: A

Rationale: When a patient presents with breathing difficulties, the first action should be to assess vital signs and breath sounds to evaluate the severity of the condition. This assessment will provide crucial information to determine the appropriate course of action and treatment. Collecting a blood sample for a white blood cell count, giving a nebulizer treatment, or administering another dose of Azmacort would not be the initial priority in this situation. Therefore, option A is the correct choice as it focuses on assessing the patient's respiratory status to guide further interventions.

3. 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.

4. What advice should be provided by the practical nurse to the mother of a school-age child with acute diarrhea and mild dehydration who is occasionally vomiting despite being given an oral rehydration solution (ORS)?

• A. Continue to give ORS frequently in small amounts.
• B. Alternate between ORS and carbonated beverages.
• C. Take the child to the hospital for intravenous fluids.
• D. Place the child NPO for the next eight to nine hours.

Correct answer: A

Rationale: The practical nurse should advise the mother to continue providing the oral rehydration solution (ORS) frequently in small amounts. It is essential to continue ORS administration to prevent dehydration, even if the child is occasionally vomiting. Small, frequent amounts of ORS help maintain hydration levels in children with acute diarrhea and mild dehydration.

5. A 13-year-old client with type 1 diabetes is admitted to the hospital with a blood glucose level of 450 mg/dL. The client is lethargic and has fruity-smelling breath. What is the nurse’s priority action?

• A. Administer insulin as prescribed
• B. Start an IV infusion of normal saline
• C. Check the client’s urine for ketones
• D. Monitor the client’s vital signs

Correct answer: B

Rationale: The correct priority action for the nurse is to start an IV infusion of normal saline. The client's presentation with lethargy, fruity-smelling breath, and high blood glucose level indicates diabetic ketoacidosis (DKA). IV fluids are essential to correct dehydration and help stabilize the client's condition. Checking for ketones in the urine is important, but fluid replacement takes precedence to address the immediate risk of dehydration and electrolyte imbalances. Administering insulin is also a crucial intervention for DKA, but fluid resuscitation should first be initiated.
