1. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

2. A client with Ménière's disease is experiencing episodes of vertigo. Which of the following interventions should the nurse include in the plan of care?

• A. Maintain strict bed rest
• B. Restrict fluid intake to the morning hours
• C. Administer aspirin
• D. Provide a low sodium diet

Correct answer: D

Rationale: The correct intervention for a client with Ménière's disease experiencing vertigo is to provide a low sodium diet. This helps reduce fluid retention, which can alleviate the symptoms of Ménière's disease. Maintaining strict bed rest is not necessary and can lead to deconditioning. Restricting fluid intake to the morning hours does not specifically address the underlying cause of Ménière's disease. Administering aspirin is not indicated for Ménière's disease and can potentially worsen symptoms.

3. What is the priority lab value for monitoring a patient with HIV?

• A. CD4 T-cell count below 180 cells/mm3
• B. Serum albumin levels
• C. White blood cell count
• D. Hemoglobin levels

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it serves as a key indicator of immune function. A count below 180 cells/mm3 indicates severe immunocompromise and an increased risk of opportunistic infections. Choice B, serum albumin levels, though important for assessing nutritional status, is not the priority lab value for HIV monitoring. Choice C, white blood cell count, is a nonspecific measure of immune function and may not accurately reflect the status of the immune system in HIV patients. Choice D, hemoglobin levels, are essential for evaluating anemia but are not the primary lab value for monitoring HIV.

4. A nurse is teaching a group of assistive personnel (AP) about caring for clients who have Alzheimer's disease. Which of the following information should the nurse include in the teaching?

• A. Explain procedures clearly and concisely to the client before initiating care
• B. Encourage a client's engagement in appropriate activities to minimize emotional outbursts
• C. Speak calmly and at a moderate volume to a client who is unable to form words or sentences
• D. Provide supervision to prevent a client from becoming injured or lost

Correct answer: D

Rationale: The correct answer is D because clients with Alzheimer's disease are at risk of wandering and becoming lost. Providing supervision helps prevent them from getting injured or lost. Choice A is incorrect because extensive details may overwhelm clients with Alzheimer's. Choice B is incorrect because limiting activities can lead to boredom and behavioral issues. Choice C is incorrect because speaking calmly and at a moderate volume helps to reduce agitation and confusion in clients with Alzheimer's.

5. A nurse in an emergency department is caring for a client who has sustained multiple injuries. The nurse observes the client's thorax moving inward during inspiration and outward during expiration. The nurse should suspect which of the following injuries?

• A. Flail chest
• B. Hemothorax
• C. Pulmonary contusion
• D. Pneumothorax

Correct answer: A

Rationale: The correct answer is A: Flail chest. Flail chest results from multiple rib fractures, causing paradoxical chest movement where the injured part moves inward during inspiration and outward during expiration, interfering with ventilation. Choice B, Hemothorax, involves blood in the pleural cavity and does not typically cause paradoxical chest movement. Choice C, Pulmonary contusion, is a bruise to the lung tissue and does not present with paradoxical chest movement. Choice D, Pneumothorax, is the presence of air in the pleural space, leading to lung collapse, but it does not demonstrate paradoxical chest movement like in flail chest.
