1. Which of the following is a characteristic symptom of multiple sclerosis (MS)?

• A. Muscle atrophy.
• B. Severe pain.
• C. Vision problems.
• D. Hearing loss.

Correct answer: C

Rationale: Vision problems are a characteristic symptom of multiple sclerosis (MS) due to demyelination of the optic nerve. This can lead to issues such as optic neuritis, blurred vision, double vision, or even total vision loss. Muscle atrophy (Choice A) is not a primary symptom of MS but can occur as a secondary effect of decreased mobility. Severe pain (Choice B) is not a typical symptom of MS, though some individuals may experience pain related to muscle spasms or other factors. Hearing loss (Choice D) is not commonly associated with MS unless there is an unrelated concurrent condition affecting the auditory system.

2. In a patient with asthma, which of the following is the most important indicator of respiratory function?

• A. Oxygen saturation.
• B. Respiratory rate.
• C. Arterial blood gases.
• D. Peak expiratory flow rate.

Correct answer: D

Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.

3. A client with cardiovascular disease is scheduled to receive a daily dose of furosemide (Lasix). Which potassium level would cause the nurse to contact the physician before administering the dose?

• A. 3.0 mEq/L
• B. 3.8 mEq/L
• C. 4.2 mEq/L
• D. 5.1 mEq/L

Correct answer: A

Rationale: The normal serum potassium level in adults ranges from 3.5 to 5.1 mEq/L. A potassium level of 3.0 mEq/L is low, indicating hypokalemia and necessitating physician notification before administering furosemide, a loop diuretic that can further lower potassium levels. Potassium levels of 3.8 and 4.2 mEq/L are within the normal range, while a level of 5.1 mEq/L is high (hyperkalemia), but the critical value in this case is the low potassium level that requires immediate attention to prevent potential complications.

4. Which of the following is the best position for a patient experiencing dyspnea?

• A. Supine position.
• B. Fowler's position.
• C. Trendelenburg position.
• D. Lateral recumbent position.

Correct answer: B

Rationale: Fowler's position is the best position for a patient experiencing dyspnea. This position involves sitting the patient upright with the head of the bed elevated between 45-60 degrees. Fowler's position helps improve breathing in patients with dyspnea by promoting lung expansion, aiding in better oxygenation, and reducing the work of breathing. The supine position (Choice A) may worsen dyspnea by limiting lung expansion. The Trendelenburg position (Choice C) with the feet elevated and the head down is not recommended for dyspnea as it can increase pressure on the chest and compromise breathing. The lateral recumbent position (Choice D) is not ideal for dyspnea as it does not provide optimal lung expansion and may not alleviate breathing difficulty.

5. Upon arrival of a client transferred to the surgical unit, what should the nurse plan to do first?

• A. Assess the patency of the airway
• B. Check tubes and drains for patency
• C. Check the dressing for bleeding
• D. Assess the vital signs to compare them with preoperative measurements

Correct answer: A

Rationale: The initial action for the nurse upon the arrival of a client to the surgical unit is to assess the patency of the airway. This step takes priority to ensure that the client has a clear airway for adequate breathing. Checking tubes and drains for patency, inspecting the dressing for bleeding, and assessing vital signs to compare with preoperative measurements are important subsequent steps in the assessment process. However, ensuring the airway is patent is the immediate priority to maintain the client's respiratory function and overall well-being.
