1. A woman who takes pyridostigmine for myasthenia gravis (MG) arrives at the emergency department complaining of extreme muscle weakness. Her adult daughter tells the nurse that since yesterday her mother has been unable to smile. Which assessment finding warrants immediate intervention by the nurse?

A. Uncontrollable drooling.
B. Inability to raise voice.
C. Tingling of extremities.
D. Eyelid drooping.

Correct answer: A

Rationale: Uncontrollable drooling can be a sign of a myasthenic crisis, which requires immediate medical intervention to prevent respiratory failure. Drooling indicates difficulty in swallowing, which can lead to aspiration and respiratory compromise. Inability to raise voice (choice B) and tingling of extremities (choice C) are not typically associated with myasthenic crisis. Although eyelid drooping (choice D) is a common symptom of myasthenia gravis, it is not as urgent as uncontrollable drooling in indicating a potential crisis.

2. A client with rheumatoid arthritis is prescribed methotrexate. Which assessment finding requires immediate intervention?

A. Fever of 100.4°F
B. Positive Chvostek's sign
C. Increased joint pain
D. Swelling in the joints

Correct answer: B

Rationale: A positive Chvostek's sign indicates hypocalcemia, which requires immediate intervention as it can lead to life-threatening complications. Fever, increased joint pain, and swelling in the joints are common symptoms in clients with rheumatoid arthritis but do not require immediate intervention like addressing hypocalcemia.

3. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should be closely monitored before the procedure?

A. Serum creatinine of 2.0 mg/dl
B. Serum potassium of 5.5 mEq/L
C. Serum calcium of 8.0 mg/dl
D. Hemoglobin of 12 g/dl

Correct answer: B

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications. Hyperkalemia can be exacerbated during hemodialysis, making it crucial to closely monitor serum potassium levels before the procedure. Monitoring serum creatinine, serum calcium, or hemoglobin levels is important in managing ESRD but is not the immediate focus before hemodialysis. Therefore, option B is the correct choice.

4. An adult female client is admitted to the psychiatric unit with a diagnosis of major depressive disorder. After starting medication therapy, the nurse notices the client has more energy, is giving away her belongings, and has an elevated mood. Which intervention is best for the nurse to implement?

A. Support the client by telling her what wonderful progress she is making.
B. Ask the client if she has had any recent thoughts of harming herself.
C. Reassure the client that the antidepressant drugs are apparently effective.
D. Tell the client to keep her belongings because she will need them at discharge.

Correct answer: B

Rationale: When a client with major depressive disorder shows signs of increased energy, giving away belongings, and an elevated mood, it could indicate a shift towards suicidal behavior. Therefore, the best intervention for the nurse is to ask the client if she has had any recent thoughts of harming herself. This is crucial to assess the client's risk for suicide and provide necessary interventions. Choices A, C, and D are incorrect because they do not address the potential risk of harm to the client and do not prioritize the immediate assessment required in this situation.

5. The nurse reviews the laboratory findings of a client with an open fracture of the tibia. The white blood cell (WBC) count and erythrocyte sedimentation rate (ESR) are elevated. Before reporting this information to the healthcare provider, what assessment should the nurse obtain?

A. Appearance of wound
B. Pain level
C. Presence of fever
D. Mobility status

Correct answer: A

Rationale: The correct answer is A: Appearance of wound. Elevated WBC and ESR levels suggest a possible infection in the client with an open fracture. Assessing the wound's appearance is crucial to evaluate for signs of infection, such as redness, warmth, swelling, or drainage. By assessing the wound first, the nurse can provide important information to the healthcare provider regarding the potential infection, which may require immediate intervention. Choices B, C, and D are important assessments in caring for a client with an open fracture; however, in this scenario, the priority is to assess the wound for signs of infection due to the elevated WBC and ESR levels.
