Nursing Elites

1. A child is hospitalized in acute renal failure and has a serum potassium greater than 7 mEq/L. What temporary measures that will produce a rapid but transient effect to reduce the potassium should the nurse expect to be prescribed? (Select all that apply.)

• A. Dialysis
• B. All below
• C. Sodium bicarbonate
• D. Glucose 50% and insulin

Correct answer: A

Rationale: Calcium gluconate, sodium bicarbonate, and glucose with insulin are used as temporary measures to rapidly reduce serum potassium levels. They help shift potassium into cells and stabilize the heart but do not remove potassium from the body like dialysis does.

2. The parents of a newborn with an umbilical hernia ask about treatment options. The nurse's response should be based on which knowledge?

• A. Surgery is recommended as soon as possible.
• B. The defect usually resolves spontaneously by 3 to 5 years of age.
• C. Aggressive treatment is necessary to reduce its high mortality.
• D. Taping the abdomen to flatten the protrusion is not recommended.

Correct answer: B

Rationale: The correct answer is B. Most umbilical hernias in newborns resolve on their own by 3 to 5 years of age without the need for surgical intervention, unless complications arise. Surgery is not typically recommended for umbilical hernias in newborns due to the high rate of spontaneous resolution. Aggressive treatment is not necessary as umbilical hernias are typically benign and not associated with high mortality. Taping the abdomen is not recommended as it can cause skin irritation and does not speed up the resolution of the hernia.

3. When teaching a discipline class for parents of pre-schoolers, the nurse will be guided by which principle?

• A. Using the strictest form of punishment at the time of infraction is most effective
• B. Punishment increases unwanted behavior
• C. Discipline is to teach and gradually shift control from parents to child, promoting self-discipline
• D. Discipline and punishment are the same

Correct answer: C

Rationale: The correct principle to guide the nurse when teaching a discipline class for parents of pre-schoolers is that discipline is meant to teach and gradually shift control from parents to the child, promoting self-discipline. This approach focuses on educating children on appropriate behavior rather than solely relying on punishment. Choice A is incorrect because using the strictest punishment is not the most effective method for discipline. Choice B is incorrect because punishment can reinforce unwanted behavior if not used appropriately. Choice D is incorrect because discipline and punishment are not synonymous; discipline involves a broader aspect of teaching and guiding behavior.

4. What is the therapeutic intervention that provides the best chance of survival for a child with cirrhosis?

• A. Nutritional support
• B. Liver transplantation
• C. Blood component therapy
• D. Treatment with corticosteroids

Correct answer: B

Rationale: Liver transplantation offers the best chance of survival for children with cirrhosis, especially in advanced stages where the liver can no longer function effectively. Cirrhosis is a late stage of scarring of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. While nutritional support, blood component therapy, and corticosteroids may be part of the treatment plan to manage symptoms and complications, they do not address the underlying cause of cirrhosis or provide a cure like liver transplantation does.

5. What test is used to screen for carbohydrate malabsorption?

• A. Stool pH
• B. Urine ketones
• C. C urea breath test
• D. ELISA stool assay

Correct answer: A

Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.
