Nursing Elites

1. The nurse is caring for a client with acute kidney injury (AKI) secondary to gentamicin therapy. The client's serum blood potassium is elevated. Which finding requires immediate action by the nurse?

• A. Anuria for the last 12 hours.
• B. Tachycardia and hypotension.
• C. Decreased urine output.
• D. Elevated blood urea nitrogen (BUN) levels.

Correct answer: A

Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.

2. A client with a tracheostomy has thick, tenacious secretions. Which intervention should the nurse include in the plan of care?

• A. Encourage the client to drink plenty of fluids.
• B. Perform deep suctioning every 2 to 4 hours.
• C. Increase humidity in the client's room.
• D. Administer a mucolytic agent.

Correct answer: C

Rationale: Increasing humidity in the client's room can help liquefy thick secretions and facilitate easier airway clearance in a client with a tracheostomy. Encouraging the client to drink plenty of fluids can be beneficial for overall hydration but may not directly address thick secretions. Deep suctioning every 2 to 4 hours can be harmful and cause trauma to the airway lining. Administering a mucolytic agent should be done under the healthcare provider's order and may not be the initial intervention for thick secretions.

3. The nurse is assisting the mother of a child with phenylketonuria (PKU) to select foods that are in keeping with the child's dietary restrictions. Which foods are contraindicated for this child?

• A. Wheat products
• B. Foods sweetened with aspartame
• C. High-fat foods
• D. High-calorie foods

Correct answer: B

Rationale: The correct answer is B: Foods sweetened with aspartame. Aspartame should not be consumed by a child with PKU because it is converted to phenylalanine in the body, which can be harmful to individuals with PKU. Choice A (Wheat products) is not specifically contraindicated for PKU. Choice C (High-fat foods) and Choice D (High-calorie foods) are not typically restricted in PKU diets unless they contain high levels of phenylalanine.

4. An adult female client with chronic kidney disease (CKD) asks the nurse if she can continue taking her over-the-counter medications. Which medication poses the greatest threat to this client?

• A. Magnesium hydroxide (Maalox).
• B. Birth control pills.
• C. Cough syrup containing codeine.
• D. Cold medication containing alcohol.

Correct answer: A

Rationale: The correct answer is A, Magnesium hydroxide (Maalox). In clients with chronic kidney disease (CKD), magnesium can accumulate to toxic levels as the kidneys are unable to excrete it efficiently. This can lead to hypermagnesemia, causing serious and potentially life-threatening complications. Birth control pills (choice B) are metabolized mainly by the liver and do not pose a significant threat to clients with CKD. Cough syrup containing codeine (choice C) should be used cautiously in CKD due to the risk of respiratory depression but does not pose as great a threat as magnesium accumulation. Cold medication containing alcohol (choice D) should be avoided in CKD but does not present the same level of danger as magnesium toxicity.

5. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?

• A. Serum glucose of 300 mg/dL
• B. Serum potassium of 4.5 mEq/L
• C. Serum bicarbonate of 15 mEq/L
• D. Serum pH of 7.28

Correct answer: D

Rationale: A serum pH of 7.28 indicates metabolic acidosis in a client with diabetic ketoacidosis (DKA), requiring immediate intervention. In DKA, the body produces excess ketones, leading to acidosis. Monitoring and correcting the pH level is crucial in managing DKA. Serum glucose levels may be high in DKA, but the immediate concern is correcting the acidosis to prevent complications. Serum potassium and bicarbonate levels are also important but not as immediately critical as correcting the acidosis in DKA.
