Nursing Elites

1. A postoperative client complains of sudden shortness of breath. What should the nurse do first?

• A. Administer oxygen
• B. Call the healthcare provider
• C. Prepare for chest x-ray
• D. Assess the client's lung sounds

Correct answer: D

Rationale: Assessing the client's lung sounds is the most appropriate initial action when a postoperative client complains of sudden shortness of breath. This step helps the nurse evaluate the respiratory status and detect abnormalities such as decreased breath sounds or crackles, which could indicate a serious condition like a pulmonary embolism. Administering oxygen (Choice A) may be necessary but should come after assessing the lung sounds to ensure the appropriate intervention. Calling the healthcare provider (Choice B) or preparing for a chest x-ray (Choice C) can be important subsequent actions based on the findings from the lung sound assessment, but they are not the first priority in this situation.

2. What is the primary purpose of a chest tube in a client's care?

• A. To drain air and fluid from the pleural space
• B. To prevent infection in the thoracic cavity
• C. To assist with lung expansion
• D. To monitor intrathoracic pressure

Correct answer: A

Rationale: The correct answer is A: To drain air and fluid from the pleural space. A chest tube is primarily used to remove accumulated air or fluid in the pleural space, preventing lung collapse or compromise of lung function. This intervention aims to re-expand the lung and enhance respiratory function. Choice B is incorrect because preventing infection is not the primary purpose of a chest tube. Choice C is incorrect as lung expansion is a result of draining the pleural space, not the primary goal. Choice D is incorrect as monitoring intrathoracic pressure is not the main objective of a chest tube insertion.

3. The nurse is assessing a client with hyperkalemia. Which finding is consistent with this electrolyte imbalance?

• A. Muscle weakness
• B. Decreased deep tendon reflexes
• C. Constipation
• D. Hypotension

Correct answer: A

Rationale: Muscle weakness is a common finding in clients with hyperkalemia. Hyperkalemia can lead to muscle weakness due to the effect of high potassium levels on muscle function. Decreased deep tendon reflexes (Choice B) are not typically associated with hyperkalemia; instead, hyperreflexia or increased reflexes may be observed. Constipation (Choice C) is not a common symptom of hyperkalemia. Hypotension (Choice D) is also not a typical finding in hyperkalemia; instead, hypertension or normal blood pressure may be present.

4. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

5. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Avoid foods high in vitamin K
• C. Increase intake of foods rich in vitamin C
• D. Limit intake of dairy products

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
