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. The nurse is caring for a client who is receiving chemotherapy. Which laboratory result indicates that the client is at risk for infection?

• A. Hemoglobin level of 12 g/dL.
• B. Platelet count of 150,000/mm3.
• C. White blood cell count of 2,000/mm3.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: C

Rationale: A white blood cell count of 2,000/mm3 is low and indicates leukopenia, which increases the client's risk for infection. Hemoglobin level and platelet count are not directly indicative of infection risk. Serum creatinine level is related to kidney function, not infection risk.

3. The patient has a calcium level of 12.1 mg/dL. Which nursing action should the nurse include on the care plan?

• A. Maintain the patient on bed rest.
• B. Auscultate lung sounds every 4 hours.
• C. Monitor for Trousseau's and Chvostek's signs.
• D. Encourage fluid intake up to 4000 mL every day.

Correct answer: D

Rationale: The correct action for the nurse to include on the care plan for a patient with a calcium level of 12.1 mg/dL is to encourage fluid intake up to 4000 mL every day. This is essential to decrease the risk for renal calculi associated with hypercalcemia. While bed rest is not necessary, ambulation is encouraged to help decrease the loss of calcium from the bone. Monitoring for Trousseau's and Chvostek's signs is more relevant when hypocalcemia is suspected. Auscultating lung sounds every shift is a routine assessment, not required every 4 hours unless there is a specific respiratory concern.

4. A 62-year-old male client with a history of coronary artery disease complains that his heart is 'racing' and he often feels dizzy. His blood pressure is 110/60, and he uses portable oxygen at 2 liters per nasal cannula. Based on the rhythm shown, which prescription should the nurse administer?

• A. Give magnesium via secondary infusion.
• B. Initiate IV heparin solution as per protocol.
• C. Administer IV adenosine (Adenocard).
• D. Prepare for synchronized cardioversion.

Correct answer: C

Rationale: Administering IV adenosine is the appropriate intervention for a client with symptomatic tachycardia to restore normal sinus rhythm. Adenosine is a medication used to treat supraventricular tachycardia (SVT) by interrupting the reentry pathways through the AV node and restoring normal sinus rhythm. It is a rapid-acting medication given as a rapid IV push followed by a saline flush. The dose is typically administered in a healthcare setting where cardiac monitoring is available due to its potential to cause transient asystole.

5. The patient described in the preceding questions has a positive H. pylori antibody blood test. She is compliant with the medical regimen you prescribe. Although her symptoms initially respond, she returns to see you six months later with the same symptoms. Which of the following statements is correct?

• A. She is at high risk for reinfection with H. pylori.
• B. A positive serum IgG indicates that eradication of H. pylori was unsuccessful.
• C. The urease breath test is an ideal test to document failure of eradication.
• D. Dyspepsia usually improves with H. pylori eradication.

Correct answer: C

Rationale: Reinfection with H. pylori is rare, and the persistence of infection usually indicates poor compliance with the medical regimen or antibiotic resistance. A positive serum IgG may persist indefinitely and cannot alone determine the failure of eradication. However, a decrease in quantitative IgG levels has been used to confirm treatment success. The urease breath test is recommended to assess the failure of eradication as it can detect the presence of H. pylori in the stomach, indicating treatment failure if positive.
