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.

A client from a nursing home is admitted with urinary sepsis and has a single-lumen, peripherally-inserted central catheter (PICC). Four medications are prescribed for 9:00 a.m. and the nurse is running behind schedule. Which medication should the nurse administer first?

• A. Piperacillin/tazobactam (Zosyn) in 100 ml D5W, IV over 30 minutes q8 hours.
• B. Vancomycin (Vancocin) 1 gm in 250 ml D5W, IV over 90 minutes q12 hours.
• C. Pantoprazole (Protonix) 40 mg PO daily.
• D. Enoxaparin (Lovenox) 40 mg subq q24 hours.

Correct Answer: A
Rationale: In a patient with urinary sepsis, administering Piperacillin/tazobactam first is crucial as it is an antibiotic that directly targets the infection. Addressing the infection promptly is essential to prevent its progression and complications. Vancomycin, Pantoprazole, and Enoxaparin are important medications for the patient's overall treatment plan, but in this scenario, the antibiotic should take precedence due to the urgency of managing the sepsis.

What is an important teaching point for a patient prescribed dabigatran for atrial fibrillation?

• A. Take the medication with food to enhance absorption.
• B. Do not crush or chew the capsules.
• C. Increase intake of green leafy vegetables.
• D. Avoid all dairy products.

Correct Answer: B
Rationale: The correct teaching point for a patient prescribed dabigatran is not to crush or chew the capsules. Doing so can alter the absorption of the medication, increasing the risk of bleeding. It is important for patients to swallow the capsules whole to ensure proper delivery of the medication.

The nurse formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely etiology for this nursing diagnosis?

• A. Pain when coughing.
• B. Diminished cough effort.
• C. Thick, dry secretions.
• D. Excessive inflammation.

Correct Answer: B
Rationale: The correct answer is B: Diminished cough effort. Clients with myasthenia gravis often experience muscle weakness, including respiratory muscles, which can lead to diminished cough effort. This weakness can result in ineffective airway clearance, putting the client at a high risk. Pain when coughing (choice A) is not directly related to the etiology of ineffective airway clearance in myasthenia gravis. While thick, dry secretions (choice C) and excessive inflammation (choice D) can contribute to airway clearance issues, the primary concern in myasthenia gravis is the muscle weakness affecting cough effort.

A client with a new diagnosis of diabetes mellitus is learning to self-administer insulin. Which instruction should the nurse include?

• A. Store the insulin in the freezer.
• B. Administer the insulin at the same site each time.
• C. Rotate injection sites within the same region.
• D. Shake the vial vigorously before drawing up the insulin.

Correct Answer: C
Rationale: The correct instruction for a client learning to self-administer insulin is to rotate injection sites within the same region. This practice helps prevent lipodystrophy, which is a condition characterized by fat tissue changes due to repeated injections in the same spot, and also ensures consistent absorption of insulin throughout the body. Storing insulin in the freezer is incorrect as it can lead to denaturation of the insulin. Administering the insulin at the same site each time can cause lipodystrophy and inconsistent absorption. Shaking the vial vigorously before drawing up the insulin is also incorrect as it can lead to insulin degradation.
