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. A client is admitted with ascites, malnutrition, and recent complaints of spitting up blood. What assessment finding warrants immediate intervention by the nurse?

• A. Capillary refill of 8 seconds
• B. Bruises on arms and legs
• C. Round and tight abdomen
• D. Pitting edema in lower legs

Correct answer: C

Rationale: A round and tight abdomen suggests fluid accumulation from ascites, which could signal a more severe underlying condition requiring immediate intervention. This finding indicates increased intra-abdominal pressure, which can lead to respiratory compromise or other serious complications. Capillary refill time, bruises on arms and legs, and pitting edema in the lower legs are important assessments but do not directly indicate the need for immediate intervention as a round and tight abdomen does in this case.

3. A client is experiencing shortness of breath and wheezing. What is the nurse's first action?

• A. Administer bronchodilator medication
• B. Check the client's oxygen saturation
• C. Encourage the client to use pursed-lip breathing
• D. Elevate the head of the bed

Correct answer: A

Rationale: Administering a bronchodilator is the priority intervention to open the airways and relieve wheezing and shortness of breath. Bronchodilators work quickly to dilate the airways, making it easier for the client to breathe. Checking oxygen saturation is important but can be done after initiating bronchodilator therapy. Encouraging pursed-lip breathing and elevating the head of the bed can help improve breathing patterns but should follow the administration of the bronchodilator.

4. A client with chronic kidney disease is prescribed a low-potassium diet. Which food should the nurse instruct the client to avoid?

• A. Carrots
• B. White bread
• C. Bananas
• D. Apples

Correct answer: C

Rationale: The correct answer is C: Bananas. Bananas are high in potassium and should be avoided in clients who are on a low-potassium diet due to chronic kidney disease. Foods like apples and white bread are low in potassium and are safer choices. Carrots are also low in potassium and do not need to be avoided in this case.

5. An older adult client is admitted with pneumonia and prescribed penicillin G potassium. Which factor increases the risk of an adverse reaction?

• A. Sputum culture showing Streptococcus pneumoniae.
• B. Previous treatment with penicillin.
• C. Daily use of spironolactone for hypertension.
• D. Documented allergy to sulfa drugs.

Correct answer: C

Rationale: The correct answer is C. Daily use of spironolactone for hypertension can increase the risk of hyperkalemia and interact with penicillin, leading to adverse reactions. Choice A is incorrect because the sputum culture showing Streptococcus pneumoniae is an expected finding in a patient with pneumonia and does not increase the risk of an adverse reaction to penicillin. Choice B is incorrect as previous treatment with penicillin does not necessarily increase the risk of an adverse reaction to penicillin if there was no history of allergic reactions. Choice D is also incorrect as a documented allergy to sulfa drugs does not directly increase the risk of an adverse reaction to penicillin.
