Nursing Elites

1. Your patient has an order to receive Levothyroxine Sodium 75 mcg daily IV. You have a vial containing 100 mcg available from the pharmacy. According to the package insert, 5 mL of 0.9% sodium chloride is needed to reconstitute. You add the appropriate amount of sodium chloride to the vial. How many mcg of medication are in 1 mL of the vial?

• A. 20 mcg
• B. 15 mcg
• C. 25 mcg
• D. 30 mcg

Correct answer: A

Rationale: After reconstitution, the concentration of Levothyroxine Sodium in the vial is 100 mcg in 5 mL, which equals 20 mcg/mL. Therefore, in 1 mL of the vial, there are 20 mcg of medication.

2. A patient with hyperthyroidism is to receive radioactive iodine therapy. What information should the nurse include in the patient teaching plan?

• A. Avoid close contact with pregnant women for one week.
• B. Take iodine supplement daily.
• C. Restrict fluid intake to 1 liter per day.
• D. Use disposable utensils for all meals.

Correct answer: A

Rationale: The correct answer is to avoid close contact with pregnant women for one week. This precaution is essential to prevent radiation exposure to vulnerable populations. Pregnant women and small children are more sensitive to radiation, making it crucial for patients undergoing radioactive iodine therapy to avoid close contact with them for a specified period. Choices B, C, and D are incorrect because taking iodine supplements daily is not necessary for patients receiving radioactive iodine therapy. Restricting fluid intake to 1 liter per day is not a standard recommendation for radioactive iodine therapy. Using disposable utensils for all meals is not a specific precaution related to radioactive iodine therapy.

3. A client is admitted with a diagnosis of acute pancreatitis. Which laboratory value should the nurse monitor closely?

• A. Serum amylase.
• B. Serum sodium.
• C. Serum calcium.
• D. Serum potassium.

Correct answer: A

Rationale: In acute pancreatitis, serum amylase is a crucial laboratory value to monitor closely. Elevated levels of serum amylase are a key indicator of pancreatic inflammation and can help confirm the diagnosis of acute pancreatitis. Therefore, monitoring serum amylase levels is essential for assessing the progression and severity of the condition in a client with acute pancreatitis.

4. The sister of a patient diagnosed with BRCA gene-related breast cancer asks the nurse, 'Do you think I should be tested for the gene?' Which response by the nurse is most appropriate?

• A. In most cases, breast cancer is not caused by the BRCA gene.
• B. It depends on how you will feel if the test is positive for the BRCA gene.
• C. There are many things to consider before deciding to have genetic testing.
• D. You should decide first whether you are willing to have a bilateral mastectomy.

Correct answer: C

Rationale: The most appropriate response by the nurse is C: 'There are many things to consider before deciding to have genetic testing.' Genetic testing for BRCA gene mutations is a complex decision that involves various factors such as emotional readiness, potential impact on insurance and employability, and the implications of test results. Option A is incorrect because although most breast cancers are not related to BRCA gene mutations, individuals with these mutations have a significantly higher risk. Option B is not ideal as it oversimplifies the decision-making process by focusing solely on emotional aspects. Option D is incorrect as it implies a predetermined course of action (mastectomy) before even undergoing genetic testing, which is not appropriate.

5. 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.
