Nursing Elites

1. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?

• A. To promote oxygenation by removing secretions.
• B. To reduce the amount of air trapped in the lungs.
• C. To increase the amount of carbon dioxide exhaled.
• D. To slow the respiratory rate and improve air exchange.

Correct answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.

2. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Serum sodium level.
• B. Serum potassium level.
• C. Serum calcium level.
• D. Serum glucose level.

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

3. Which instruction should be included in the discharge teaching plan for an adult client with hypernatremia?

• A. Monitor daily urine output volume
• B. Drink plenty of water whenever thirsty
• C. Use salt tablets for sodium content
• D. Review food labels for sodium content

Correct answer: D

Rationale: In hypernatremia, there is an excess of sodium in the blood. Reviewing food labels for sodium content is crucial as it helps the client identify and avoid high-sodium foods, which can contribute to elevated sodium levels. Monitoring urine output volume may be important for other conditions but is not directly related to managing hypernatremia. Drinking water whenever thirsty is generally good advice for staying hydrated but does not specifically address the issue of high sodium levels. Using salt tablets would worsen hypernatremia by further increasing sodium intake.

4. A client who has a body mass index (BMI) of 30 is requesting information on the initial approach to a weight loss plan. Which action should the nurse recommend first?

• A. Plan low carbohydrate and high protein meals
• B. Engage in strenuous activity for an hour daily
• C. Keep a record of food and drinks consumed daily
• D. Participate in a group exercise class 3 times a week

Correct answer: C

Rationale: Keeping a food diary is a good first step to understand eating habits before making any dietary or activity changes.

5. A client with a history of coronary artery disease (CAD) is admitted with chest pain. Which intervention should the nurse implement first?

• A. Administer sublingual nitroglycerin
• B. Obtain a 12-lead electrocardiogram (ECG)
• C. Apply oxygen via nasal cannula
• D. Initiate continuous cardiac monitoring

Correct answer: C

Rationale: In a client with a history of coronary artery disease (CAD) experiencing chest pain, the priority intervention for the nurse to implement first is to apply oxygen via nasal cannula. Oxygenation is crucial to ensure adequate oxygen supply to the tissues and the heart. This intervention takes precedence over administering sublingual nitroglycerin, obtaining an ECG, or initiating continuous cardiac monitoring. While these interventions are important, ensuring adequate oxygenation is the initial priority in the management of a client with chest pain.
