Nursing Elites

1. A client with chronic liver disease is prescribed lactulose. Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Bilirubin level
• B. Serum ammonia level
• C. Serum potassium level
• D. Albumin level

Correct answer: B

Rationale: The correct answer is B: Serum ammonia level. Lactulose is used to lower serum ammonia levels in clients with chronic liver disease, particularly in cases of hepatic encephalopathy. Monitoring serum ammonia levels is crucial to evaluate the effectiveness of lactulose in managing hepatic encephalopathy. Choices A, C, and D are incorrect because they are not directly related to the action or evaluation of lactulose in chronic liver disease.

2. The nurse prepares to teach clients about blood glucose monitoring. When should clients always check glucose, regardless of age or type of diabetes?

• A. Before going to bed.
• B. After meals.
• C. During acute illness.
• D. Prior to exercising.

Correct answer: C

Rationale: The correct answer is C: During acute illness. Checking blood glucose during acute illness is crucial as stress can elevate glucose levels. This monitoring is essential regardless of the client's age or the type of diabetes they have. Checking before going to bed (choice A) may be important for some individuals, but it's not as universally necessary as during acute illness. Checking after meals (choice B) and prior to exercising (choice D) are important times for monitoring blood glucose, but they are not as universally applicable as during acute illness.

3. A client with rheumatoid arthritis has just been prescribed methotrexate. What teaching should the nurse include?

• A. Take the medication on an empty stomach.
• B. Report any signs of infection, such as a sore throat.
• C. Take folic acid supplements to prevent anemia.
• D. Use sunscreen to prevent photosensitivity.

Correct answer: D

Rationale: The correct answer is D: 'Use sunscreen to prevent photosensitivity.' Methotrexate increases photosensitivity, so clients should be advised to use sunscreen to protect their skin from sun exposure. Choice A is incorrect because methotrexate is usually taken with food to reduce gastrointestinal side effects. Choice B may be important but is not specific to methotrexate therapy. Choice C is also important, but the primary reason for folic acid supplementation with methotrexate is to reduce the risk of certain side effects like anemia rather than preventing anemia itself.

4. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

5. 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.
