1. A healthcare professional is reviewing laboratory results for a client with rheumatoid arthritis prescribed methotrexate. Which of the following laboratory results should the healthcare professional report to the provider?

Correct answer: A

Rationale: A WBC count of 1,200/mm³ indicates leukopenia, a serious side effect of methotrexate that can lead to increased risk of infections. It is crucial to report this finding promptly to the provider for further evaluation and possible adjustments in the treatment plan. Choices B, C, and D are within normal ranges and do not represent significant concerns related to methotrexate therapy in this context.

2. The nurse is assisting with the care of a client who is on a continuous heparin infusion for deep vein thrombosis (DVT). Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?

Correct answer: B

Rationale: To evaluate the effectiveness of heparin therapy in a client with DVT, the nurse should monitor the activated partial thromboplastin time (aPTT). The aPTT test helps ensure that the dose of heparin is within the therapeutic range, which is essential for preventing clot formation or excessive bleeding. Monitoring aPTT is crucial in managing patients on heparin therapy to maintain the delicate balance between preventing thrombosis and avoiding hemorrhage. Prothrombin time (PT) and International normalized ratio (INR) are more indicative of warfarin therapy effectiveness, not heparin. Platelet count assesses platelet levels and function, not the effectiveness of heparin therapy for DVT.

3. The client with heart failure is receiving digoxin (Lanoxin). The nurse should monitor the client for which sign of digoxin toxicity?

Correct answer: B

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin can cause disturbances in the heart's electrical conduction system, leading to a slower heart rate. Therefore, the nurse should closely monitor the client's heart rate for signs of bradycardia, which could indicate digoxin toxicity. Hypertension (Choice A), hyperglycemia (Choice C), and insomnia (Choice D) are not typically associated with digoxin toxicity. Therefore, they are incorrect choices for this question.

4. A healthcare professional is assessing a client who has been taking lithium carbonate for bipolar disorder. Which of the following findings should the professional report to the provider?

Correct answer: B

Rationale: Tremors are a concerning sign of lithium toxicity that indicate a potential overdose. Tremors can progress to more severe symptoms if not addressed promptly. Reporting tremors promptly allows the provider to assess the client's lithium levels, adjust the dosage, or provide appropriate interventions to prevent further complications. Increased urination, weight gain, and blurred vision are potential side effects of lithium but are not indicative of toxicity or overdose. While they should still be monitored, they are not as urgent as tremors in the context of lithium therapy.

5. A client with chronic obstructive pulmonary disease (COPD) is prescribed theophylline. The nurse should monitor the client for which sign of theophylline toxicity?

Correct answer: C

Rationale: Nausea is an early sign of theophylline toxicity. The nurse should closely monitor the client for this symptom as it can progress to more severe toxicity. Nausea can be a warning sign to prevent further complications and adjust the dosage as necessary. Drowsiness (choice A) is a common side effect of theophylline but not a specific sign of toxicity. Bradycardia (choice B) and constipation (choice D) are not typically associated with theophylline toxicity. Therefore, the correct answer is C.
