Nursing Elites

1. A patient is admitted with a diagnosis of myasthenia gravis. What symptom should the nurse expect to find during the assessment?

• A. Joint pain
• B. Muscle weakness
• C. Loss of sensation
• D. Severe headache

Correct answer: B

Rationale: Myasthenia gravis is a neuromuscular disorder characterized by muscle weakness and fatigue, especially in the voluntary muscles. Patients with myasthenia gravis commonly experience weakness in muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. This weakness typically worsens with activity and improves with rest. Joint pain, loss of sensation, and severe headaches are not typical symptoms of myasthenia gravis. Therefore, the correct answer is muscle weakness (choice B) as it aligns with the characteristic symptom of myasthenia gravis.

2. What is the primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT)?

• A. No need for regular INR monitoring
• B. Lower risk of bleeding
• C. Fewer dietary restrictions
• D. Longer half-life

Correct answer: A

Rationale: The primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT) is that rivaroxaban does not require regular INR monitoring. This eliminates the need for frequent blood tests to adjust the dosage, making it more convenient for patients to manage their anticoagulant therapy.

3. 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.

4. What is the primary action of digoxin when prescribed to a patient with heart failure?

• A. Increase heart rate
• B. Decrease cardiac output
• C. Strengthen cardiac contractions
• D. Lower blood pressure

Correct answer: C

Rationale: Digoxin, when prescribed to a patient with heart failure, primarily acts by strengthening cardiac contractions. This leads to an improvement in cardiac output, making it an essential medication in managing heart failure. By enhancing the force of contractions, digoxin helps the heart pump more effectively and efficiently, leading to better circulation and symptom control in patients with compromised cardiac function.

5. A patient with tuberculosis is started on rifampin. What advice should the nurse provide?

• A. Limit intake of green leafy vegetables.
• B. Expect orange-red discoloration of body fluids.
• C. Avoid exposure to sunlight.
• D. Take the medication with antacids.

Correct answer: B

Rationale: The correct advice for a patient starting rifampin is to expect orange-red discoloration of body fluids. Rifampin can cause harmless orange-red discoloration of body fluids, which may include urine, sweat, saliva, and tears. It is important for the patient to be aware of this side effect as it can stain clothing and contact lenses. Limiting the intake of green leafy vegetables is not necessary with rifampin. Avoiding exposure to sunlight is more commonly associated with other medications like tetracyclines, not rifampin. Taking rifampin with antacids is not recommended as antacids can reduce the absorption of rifampin, decreasing its effectiveness in treating tuberculosis.
