1. What should be monitored to evaluate the effectiveness of enoxaparin in a patient with deep vein thrombosis (DVT)?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: C

Rationale: The international normalized ratio (INR) is the appropriate parameter to monitor the effectiveness of enoxaparin in preventing clot formation in patients with deep vein thrombosis (DVT). INR reflects the clotting ability of the blood and is commonly used to assess the therapeutic range of anticoagulant medications, such as enoxaparin, which is crucial in managing and preventing thrombotic events like DVT.

2. A client with hypothyroidism is started on levothyroxine (Synthroid). Which statement by the client indicates a need for further teaching?

• A. I will take this medication every morning before breakfast.
• B. I should have my thyroid levels checked regularly.
• C. If I lose weight, I may need an increased dose.
• D. I can stop taking this medication once my symptoms improve.

Correct answer: D

Rationale: The correct answer is D. Levothyroxine is typically a lifelong therapy for hypothyroidism. It should not be discontinued even if symptoms improve because the medication helps replace the deficient thyroid hormone. Stopping the medication prematurely can lead to a recurrence of symptoms and potential complications. Patients must understand the importance of continuous levothyroxine therapy and the necessity of regular follow-up with their healthcare provider to monitor thyroid levels and adjust the dosage as needed.

3. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.

4. A client with diabetes has a new prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that should be prepared in the insulin syringe?

• A. 42 units
• B. 14 units
• C. 28 units
• D. 32 units

Correct answer: A

Rationale: To calculate the total number of units of insulin, you need to add the 14 units of regular insulin to the 28 units of NPH insulin, which equals 42 units. Therefore, the nurse should prepare 42 units of insulin in the syringe for the client.

5. A 30-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The clinical presentation of a 30-year-old woman with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria is highly suggestive of type 1 diabetes mellitus. Type 1 diabetes mellitus is characterized by autoimmune destruction of pancreatic beta cells, leading to insulin deficiency and subsequent hyperglycemia. The presence of ketonuria indicates the breakdown of fats for energy due to the lack of insulin. In contrast, type 2 diabetes mellitus typically presents with gradual onset and is often associated with insulin resistance rather than absolute insulin deficiency. Diabetes insipidus is characterized by polyuria and polydipsia but is not associated with hyperglycemia or ketonuria. Hyperthyroidism may present with symptoms like fatigue but does not typically cause hyperglycemia or ketonuria.
