Nursing Elites

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?

• 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 XXX muscle groups of males.
• D. Spinal cord damage due to birth trauma during a breech vaginal birth weakens the muscles.

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. Albumin 25% IV is prescribed for a child with nephrotic syndrome. Which assessment finding indicates to the nurse that the medication is having the desired effect?

• A. Weight gain.
• B. Reduction of fever.
• C. Improved caloric intake.
• D. Reduction of edema.

Correct answer: D

Rationale: The correct answer is D: Reduction of edema. Albumin helps reduce edema by increasing oncotic pressure, drawing fluid back into the blood vessels. In nephrotic syndrome, there is an abnormal loss of protein in the urine, leading to decreased oncotic pressure and fluid shifting into the interstitial spaces, causing edema. Administering albumin helps restore the oncotic pressure, reducing edema, which is a desirable effect of the medication.

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

• A. Place the infant in a knee-chest position.
• B. Administer morphine sulfate.
• C. Start intravenous fluids.
• D. Provide 100% oxygen by face mask.

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. The nurse is caring for a one-year-old child following surgical correction of hypospadias. Which nursing action has the highest priority?

• A. Monitor urinary output
• B. Auscultate bowel sounds
• C. Observe appearance of stool
• D. Record percent of diet consumed

Correct answer: A

Rationale: In caring for a one-year-old child post hypospadias surgery, the highest priority action is to monitor urinary output. This is crucial to assess kidney function and ensure there are no complications following the surgical procedure. Auscultating bowel sounds, observing stool appearance, and recording diet consumption are important assessments too, but in this case, monitoring urinary output takes precedence due to the nature of the surgery and potential complications related to urinary function.

5. A loading dose of terbutaline (Brethine) 250 mcg IV is prescribed for a client in preterm labor. Brethine 20 mg is added to 1,000 mL of D5W. How many milliliters of the solution should the nurse administer?

• A. 45
• B. 15 mL
• C. 4
• D. 13

Correct answer: D

Rationale: To calculate the amount of terbutaline to administer, first convert the dose to the same unit. 250 mcg = 0.25 mg. Next, set up a proportion: 20 mg is to 1000 mL as 0.25 mg is to X mL. Cross multiply and solve for X: 20 × X = 0.25 × 1000. X = (0.25 × 1000) / 20 = 12.5 mL. Therefore, the nurse should administer 13 mL of the solution. Choice A is incorrect as it does not reflect the correct calculation. Choice B is incorrect as it does not consider the accurate conversion and calculation. Choice C is incorrect as it is not the result of the correct proportion calculation.
