Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. The client is being taught to choose foods rich in potassium to prevent digitalis toxicity. Which choice indicates the client understands dietary needs?

• A. Three apricots
• B. Medium banana
• C. Naval orange
• D. Baked potato

Correct answer: D

Rationale: The correct answer is D: Baked potato. Baked potatoes are rich in potassium, which is essential in preventing digitalis toxicity by helping to maintain normal electrolyte levels. Apricots, bananas, and oranges are also sources of potassium, but a baked potato has a higher potassium content compared to the other options, making it a more effective choice for preventing digitalis toxicity.

3. A client with gastroesophageal reflux disease (GERD) is prescribed omeprazole. What is the primary purpose of this medication?

• A. Coat the lining of the stomach
• B. Neutralize stomach acid
• C. Promote gastric motility
• D. Reduce gastric acid secretion

Correct answer: D

Rationale: The correct answer is D: Reduce gastric acid secretion. Omeprazole is a proton pump inhibitor that works by reducing the production of gastric acid in the stomach. This helps in managing GERD by decreasing the acidity levels in the stomach. Choice A is incorrect because omeprazole does not coat the lining of the stomach. Choice B is incorrect as omeprazole does not neutralize stomach acid but rather reduces its production. Choice C is incorrect because omeprazole does not promote gastric motility; instead, it acts on acid secretion.

4. A client admitted with left-sided heart failure presents with shortness of breath and pink frothy sputum. Which assessment finding requires immediate intervention?

• A. Decreased breath sounds bilaterally.
• B. Heart rate of 110 bpm and irregular rhythm.
• C. Pink frothy sputum and increased respiratory rate.
• D. Elevated blood pressure and shortness of breath.

Correct answer: C

Rationale: Correct Answer: Pink frothy sputum and increased respiratory rate. Pink frothy sputum is a sign of pulmonary edema, indicating fluid in the lungs, a life-threatening condition that requires immediate intervention to prevent respiratory failure. Increased respiratory rate is also concerning as it indicates the body's effort to compensate for the decreased oxygenation. Options A, B, and D are not the most critical findings in this situation. Decreased breath sounds bilaterally may indicate a pneumothorax or atelectasis, heart rate of 110 bpm and irregular rhythm can be managed with medications and further assessment, and elevated blood pressure with shortness of breath is not as urgent as pink frothy sputum and increased respiratory rate.

5. A client with diabetes mellitus is experiencing diabetic ketoacidosis (DKA). What laboratory result should the nurse monitor closely?

• A. White blood cell count of 15,000.
• B. Blood glucose level of 320 mg/dL.
• C. Sodium level of 145 mEq/L.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: B

Rationale: A blood glucose level of 320 mg/dL indicates the need for insulin to manage diabetic ketoacidosis.
