Nursing Elites

1. When assessing a client with left-sided heart failure, which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Monitor the client's urine output.
• C. Administer a loop diuretic as prescribed.
• D. Administer morphine as prescribed.

Correct answer: A

Rationale: Administering oxygen therapy is the initial intervention for a client with left-sided heart failure. This action is crucial in improving oxygen levels and reducing pulmonary congestion. Monitoring urine output is important for assessing renal function in heart failure, but it is not the priority over ensuring adequate oxygenation. Administering loop diuretics helps manage fluid overload but should come after addressing oxygen needs. Morphine may be indicated for pain or anxiety in some cases, but it is not the primary intervention for left-sided heart failure.

2. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?

• A. Administer intravenous calcium gluconate.
• B. Administer intravenous insulin and glucose.
• C. Administer intravenous sodium bicarbonate.
• D. Administer a loop diuretic as prescribed.

Correct answer: B

Rationale: The correct answer is to administer intravenous insulin and glucose first. This intervention helps drive potassium back into the cells, lowering serum levels effectively. Administering intravenous calcium gluconate (choice A) is used to stabilize cardiac membranes in severe hyperkalemia but does not address the underlying cause. Administering intravenous sodium bicarbonate (choice C) is used in metabolic acidosis, not hyperkalemia. Administering a loop diuretic (choice D) can help eliminate potassium but is not the first-line treatment for hyperkalemia in CKD.

3. A client with a tracheostomy is experiencing thick, tenacious secretions. Which intervention should the nurse implement first?

• A. Encourage fluid intake to thin secretions.
• B. Administer a mucolytic agent.
• C. Increase humidity in the client's room.
• D. Perform deep suctioning as needed.

Correct answer: C

Rationale: Increasing humidity in the client's room is the initial intervention for managing thick, tenacious secretions in a client with a tracheostomy. Adequate humidity helps to hydrate secretions, making them easier to clear, thus improving airway clearance. Encouraging fluid intake (Choice A) can be beneficial but is not the first-line intervention. Administering a mucolytic agent (Choice B) may be considered if increasing humidity alone is insufficient. Performing deep suctioning (Choice D) should be reserved for when other measures like increasing humidity have been ineffective.

4. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.0 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum glucose of 300 mg/dL

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.

5. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?

• A. Frequency of laxative use for chronic constipation
• B. Dietary intake of magnesium-rich foods
• C. Use of magnesium-containing supplements
• D. History of alcohol use

Correct answer: A

Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.
