1. A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?

• A. Inflammation of the synovial membrane.
• B. Degeneration of the cartilage in the joint.
• C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
• D. Formation of uric acid crystals in the joint space.

Correct answer: C

Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.

2. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?

• A. Metabolic acidosis.
• B. Respiratory acidosis.
• C. Metabolic alkalosis.
• D. Respiratory alkalosis.

Correct answer: B

Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.

3. When assessing an adolescent with depression, what is the most important question for the nurse to ask?

• A. What is causing your feelings of depression?
• B. Have you ever thought about suicide?
• C. What actions can we take to improve your mood?
• D. Would you like your friends to come over?

Correct answer: B

Rationale: The correct answer is B: 'Have you ever thought about suicide?' When assessing an adolescent with depression, it is crucial to ask direct questions about suicidal thoughts. This helps determine the severity of the situation, especially if the person has considered or planned to harm themselves. Choice A is not as direct and specific to suicidal ideation. Choice C focuses on improving mood rather than assessing the risk of harm. Choice D is unrelated to assessing suicidal ideation and the severity of the depression.

4. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Administer potassium supplements orally.
• B. Increase the client's dietary potassium intake.
• C. Inform the healthcare provider of the need for potassium replacement.
• D. Monitor the client's ECG continuously.

Correct answer: C

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.

5. Before selecting which medication to administer, which action should the nurse implement if a postoperative client reports incisional pain and has two prescriptions for PRN analgesia?

• A. Compare the client’s pain scale rating with the prescribed dosing.
• B. Determine which prescription will have the quickest onset of action.
• C. Ask the client to choose which medication is needed for the pain.
• D. Document the client’s report of pain in the electronic medical record.

Correct answer: A

Rationale: When a postoperative client reports incisional pain and has two prescriptions for PRN analgesia, the nurse should first compare the client’s pain scale rating with the prescribed dosing. This action ensures that the client receives the appropriate medication based on their pain level. Determining the onset of action or asking the client to choose the medication does not guarantee that the right medication is administered according to the pain intensity. Documenting the pain report is important but should not be the first action when deciding which medication to administer.
