Nursing Elites

1. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

2. A client with chronic obstructive pulmonary disease (COPD) is being discharged home. What should the nurse include in the discharge teaching?

• A. Limit fluid intake to prevent lung congestion
• B. Avoid all physical activity to conserve energy
• C. Perform pursed-lip breathing during activities
• D. Increase oxygen flow rate if shortness of breath occurs

Correct answer: C

Rationale: The correct answer is C. Pursed-lip breathing helps control breathing and improves oxygen exchange in clients with COPD. It can ease shortness of breath during activities and should be included in discharge teaching to manage symptoms. Option A is incorrect as adequate fluid intake is important for thinning mucus in COPD. Option B is wrong as physical activity, as tolerated, is beneficial for COPD patients. Option D is also incorrect because changing oxygen flow rate without healthcare provider guidance can be dangerous.

3. A client receiving chemotherapy for cancer treatment is experiencing nausea and vomiting. What is the nurse's best intervention to manage these symptoms?

• A. Offer frequent, small meals
• B. Administer antiemetics before meals
• C. Encourage the client to eat a high-fat diet
• D. Provide the client with cold, carbonated beverages

Correct answer: B

Rationale: Administering antiemetics before meals is the best intervention to manage nausea and vomiting in clients receiving chemotherapy. This proactive approach helps control symptoms by preventing nausea from occurring, rather than waiting to treat it once symptoms have already started. Offering frequent, small meals (choice A) may worsen symptoms in some cases due to increased stomach activity. Encouraging a high-fat diet (choice C) can be difficult for nauseated clients and may not alleviate symptoms. Providing cold, carbonated beverages (choice D) could exacerbate nausea further due to the temperature and carbonation.

4. A 5-week-old infant with hypertrophic pyloric stenosis has developed projectile vomiting over the last two weeks. Which intervention should the nurse plan to implement?

• A. Instruct the mother to give sugar water only.
• B. Offer the infant oral rehydration every 2 hours.
• C. Provide Pedialyte feedings via nasogastric tube.
• D. Maintain intravenous fluid therapy.

Correct answer: D

Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.

5. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.
