Nursing Elites

1. Parents of a child who will need hemodialysis ask the nurse, What are the advantages of a fistula over a graft or external access device for hemodialysis? (Select all that apply.)

• A. It is ready to be used immediately.
• B. All below
• C. There is less restriction of activity with a fistula.
• D. It produces dilation and thickening of the superficial vessels.

Correct answer: A

Rationale: A fistula typically has fewer complications, allows for greater freedom of movement, and involves natural vessel changes that improve dialysis efficiency. However, it is not ready for immediate use, which is why it may take weeks to mature before it can be used.

2. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

3. Surgery is performed on a child to correct cryptorchidism. The parents understand the reason for the surgery if they tell the nurse this was done to do what?

• A. Prevent damage to the undescended testicle.
• B. Prevent urinary tract infections.
• C. Prevent prostate cancer.
• D. Prevent an inguinal hernia.

Correct answer: A

Rationale: The primary reason for correcting cryptorchidism through surgery is to prevent damage to the undescended testicle, which can lead to infertility and increase the risk of testicular cancer. Prevention of UTIs and prostate cancer are not the primary concerns in this context.

4. When should the nurse instruct parents to administer a daily proton pump inhibitor to their child with gastroesophageal reflux?

• A. At bedtime
• B. With a meal
• C. Midmorning
• D. 30 minutes before breakfast

Correct answer: D

Rationale: Proton pump inhibitors (PPIs) like omeprazole or lansoprazole are most effective when given 30 minutes before breakfast. This timing allows the medication to inhibit the proton pumps in the stomach that produce acid, providing better symptom control throughout the day. Administering the PPI at bedtime (choice A) may not be as effective as giving it before breakfast due to the timing of peak acid production during the day. Giving it with a meal (choice B) might affect the absorption and effectiveness of the medication. Midmorning administration (choice C) is not the recommended time for optimal PPI efficacy.

5. Frequent urine tests for specific gravity are required on a 6-month-old infant. What method is the most appropriate way to collect small amounts of urine for these tests?

• A. Apply a urine collection bag to the perineal area.
• B. Tape a small medicine cup inside of the diaper.
• C. Aspirate urine from cotton balls inside the diaper with a syringe without a needle.
• D. Use a syringe without a needle to aspirate urine from a superabsorbent disposable diaper.

Correct answer: C

Rationale: Aspirating urine from cotton balls inside the diaper is a minimally invasive method and effective for collecting small amounts of urine. Using a collection bag can be more cumbersome, and other methods are not as effective for this age.
