Nursing Elites

1. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Serum glucose level
• C. White blood cell count
• D. Prothrombin time (PT)

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.

2. 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.

3. The nurse is assisting the mother of a child with phenylketonuria (PKU) to select foods that are in keeping with the child's dietary restrictions. Which foods are contraindicated for this child?

• A. Wheat products
• B. Foods sweetened with aspartame
• C. High-fat foods
• D. High-calorie foods

Correct answer: B

Rationale: The correct answer is B: Foods sweetened with aspartame. Aspartame should not be consumed by a child with PKU because it is converted to phenylalanine in the body, which can be harmful to individuals with PKU. Choice A (Wheat products) is not specifically contraindicated for PKU. Choice C (High-fat foods) and Choice D (High-calorie foods) are not typically restricted in PKU diets unless they contain high levels of phenylalanine.

4. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which assessment finding is most concerning?

• A. Increased fatigue
• B. Headache
• C. Elevated blood pressure
• D. Low urine output

Correct answer: C

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, an elevated blood pressure is the most concerning assessment finding. This finding can indicate worsening hypertension, which requires prompt intervention to prevent complications such as cardiovascular events or further kidney damage. Increased fatigue (Choice A) is a common symptom in CKD and can be expected with the condition itself or the treatment. Headache (Choice B) can also occur but is less specific to CKD or its treatment. Low urine output (Choice D) is a concern in CKD but may not be directly related to erythropoietin therapy.

5. The nurse is assessing a client with chronic heart failure who is receiving furosemide (Lasix). Which assessment finding is most concerning?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Elevated liver enzymes
• D. Elevated blood glucose level

Correct answer: C

Rationale: Elevated liver enzymes are most concerning in a client with chronic heart failure as they may indicate liver congestion or worsening heart failure, requiring immediate intervention. Elevated liver enzymes can be a sign of hepatotoxicity or liver damage, which could be a result of furosemide (Lasix) use. Monitoring liver function is crucial in patients taking furosemide due to the risk of hepatotoxicity. A heart rate of 60 beats per minute and a blood pressure of 110/70 mmHg are within normal ranges for a client with chronic heart failure. An elevated blood glucose level may be expected due to the effects of furosemide but is not as immediately concerning as elevated liver enzymes.
