1. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.

2. A 48-year-old man presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The scenario describes a classic presentation of hypothyroidism, supported by the laboratory findings of high TSH and low free T4 levels. In hypothyroidism, the body's thyroid hormone levels are inadequate, leading to symptoms like fatigue, weight gain, and cold intolerance. High TSH is a compensatory mechanism by the body to increase thyroid hormone production, which is deficient, resulting in a negative feedback loop. Therefore, the correct answer is hypothyroidism.

3. The client is receiving intravenous (IV) morphine for pain control. Which assessment finding requires the most immediate intervention?

• A. Drowsiness.
• B. Itching.
• C. Nausea.
• D. Respiratory rate of 8 breaths per minute.

Correct answer: D

Rationale: A respiratory rate of 8 breaths per minute indicates severe respiratory depression, a life-threatening side effect of opioid therapy. Immediate intervention is crucial to prevent respiratory failure. Monitoring and managing respiratory status are critical in clients receiving opioids to prevent adverse events. Drowsiness, itching, and nausea are common side effects of morphine but are not as immediately life-threatening as severe respiratory depression.

4. In a patient with a history of chronic iron deficiency anemia requiring a recent blood transfusion and an extensive GI work-up, which statement is true based on their medications?

• A. A dedicated small bowel series has a high likelihood of being positive
• B. 81 mg of aspirin per day decreases the benefit of using a COX II inhibitor
• C. The patient should have a provocative arteriogram with heparin infusion to identify the source of blood loss
• D. Hormonal therapy has been shown to be effective in decreasing blood loss due to arteriovenous malformations

Correct answer: B

Rationale: The correct answer is B. Taking even a low dose of aspirin per day, such as 81 mg, can reduce the protective effect on the gastrointestinal mucosa that is gained from using a COX II selective inhibitor. Aspirin can increase the risk of gastrointestinal bleeding, which can counteract the benefits of COX II inhibitors in protecting the stomach lining.

5. During the initial assessment of a client with a history of substance abuse admitted for detoxification, which intervention is most important?

• A. Obtain a detailed substance use history.
• B. Establish a trusting nurse-client relationship.
• C. Evaluate the client's physical health status.
• D. Determine the client's readiness for change.

Correct answer: C

Rationale: Assessing the client's physical health status is the most critical intervention during the initial assessment of a client with a history of substance abuse admitted for detoxification. This evaluation helps identify and address any immediate health risks, such as withdrawal symptoms or medical complications, to ensure the client's safety and well-being during the detoxification process. Option A, obtaining a detailed substance use history, is important but not the most critical initially. Option B, establishing a trusting nurse-client relationship, is important but assessing physical health takes precedence. Option D, determining the client's readiness for change, is valuable but assessing physical health for immediate risks is the priority.
