What is the most appropriate intervention for a client with hyperkalemia?

Correct Answer: C

Rationale: The correct intervention for hyperkalemia is to administer insulin (Choice C). Insulin drives potassium into cells, lowering serum potassium levels. This is effective in acutely reducing high potassium levels. Administering calcium gluconate (Choice A) is used for stabilizing cardiac membranes in hyperkalemia but does not lower potassium levels. Sodium bicarbonate (Choice B) is used for metabolic acidosis, not hyperkalemia. Furosemide (Choice D) is a loop diuretic that can lead to potassium loss but is not the primary intervention for hyperkalemia.

Correct Answer: A

Rationale: The correct answer is A: Place the client in a safe environment. This is the primary intervention for a client with a history of falls to prevent further injury. By ensuring the environment is safe, the risk of falls and subsequent injuries is minimized. Choice B, assessing the client's functional status, is important but not the primary intervention. Choice C, encouraging the client to rest, may not address the underlying issue of fall risk. Choice D, encouraging the client to ambulate, may increase the risk of falls for someone with a history of falls. It is crucial to prioritize safety by modifying the environment to prevent falls.

Correct Answer: D

Rationale: The correct answer is D: Encourage deep breathing exercises. For a client with a history of asthma and wheezing, deep breathing exercises help improve lung function and reduce the frequency of asthma attacks. These exercises can strengthen respiratory muscles, increase lung capacity, and enhance overall breathing efficiency. Administering bronchodilators (choice A) may provide immediate relief but does not address long-term management. Administering oxygen and encouraging fluid intake (choice B) may be helpful in certain situations but does not specifically target asthma symptoms. Administering corticosteroids (choice C) is typically used for severe asthma exacerbations and should not be the first-line treatment for someone with a history of asthma and wheezing.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In respiratory distress, the priority is to ensure adequate oxygenation. Oxygen therapy helps improve oxygen levels in the blood and relieve respiratory distress. Administering diuretics (B) may not address the immediate need for oxygen. Increasing respiratory rate (C) may lead to worsening distress if the underlying cause is not addressed. Administering IV fluids (D) is not the priority unless specifically indicated for the client's condition. It is crucial to prioritize oxygen delivery to support vital functions and stabilize the client's condition.

Correct Answer: B

Rationale: The correct answer is B: Provide IV fluids. The first step in caring for a client with severe burn injuries is to ensure adequate hydration and prevent hypovolemic shock. IV fluids are crucial to replace lost fluids and maintain circulation. Cooling the burn site (choice A) may be important but not the first step. Providing pain relief (choice C) is important but not as critical initially. Initiating IV fluids (choice D) is similar to the correct answer, but providing IV fluids is more urgent than initiating them.
