Nursing Elites

1. A client with cirrhosis is admitted with jaundice, fatigue, and a distended abdomen. Which laboratory result is most important for the nurse to monitor?

• A. Ammonia level
• B. White blood cell count
• C. Albumin level
• D. Hemoglobin level

Correct answer: A

Rationale: Corrected Rationale: In clients with cirrhosis, elevated ammonia levels can lead to hepatic encephalopathy, which is a serious complication. Monitoring ammonia levels is crucial to assess for changes in mental status and initiate treatment if needed. White blood cell count (choice B) is not the most important parameter to monitor in this scenario as it does not directly relate to the complications of cirrhosis. Albumin level (choice C) and hemoglobin level (choice D) are also important in cirrhosis, but in this case, monitoring ammonia level takes precedence due to its direct association with hepatic encephalopathy.

2. The nurse is caring for a client with a history of congestive heart failure (CHF) who is receiving digoxin therapy. The client reports seeing halos around lights. Which action should the nurse take?

• A. Assess the client's digoxin level
• B. Increase the client's fluid intake
• C. Check the client's blood pressure
• D. Administer a dose of potassium

Correct answer: A

Rationale: Seeing halos around lights is a classic symptom of digoxin toxicity. The nurse should assess the client's digoxin level to determine if the dose needs to be adjusted or if the medication should be held. Increasing fluid intake or checking blood pressure would not directly address the symptom of halos around lights. Administering a dose of potassium is not indicated without knowing the digoxin level and could potentially worsen the toxicity.

3. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

4. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

5. 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.
