1. What are the early signs of hypokalemia on an ECG?

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

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. In hypokalemia, the T waves may flatten and eventually invert. Elevated ST segments are not typically associated with hypokalemia. Prominent U waves are seen in conditions like hypokalemia, but they are not considered an early sign. A widened QRS complex is more commonly associated with hyperkalemia rather than hypokalemia.

2. A nurse is providing discharge teaching for a client who has COPD about nutrition. Which of the following instructions should the nurse include?

• A. Eat three large meals daily
• B. Consume high-calorie foods
• C. Limit caffeinated drinks to two per day
• D. Drink fluids during meal time

Correct answer: B

Rationale: The correct answer is B: 'Consume high-calorie foods.' Clients with COPD often have increased energy needs due to the work of breathing. Consuming high-calorie, high-protein foods can help provide the necessary energy and prevent weight loss. Choice A is incorrect because eating three large meals daily may lead to increased shortness of breath due to a full stomach putting pressure on the diaphragm. Choice C is incorrect because caffeinated drinks can contribute to dehydration, which is not ideal for clients with COPD. Choice D is incorrect because drinking fluids during mealtime can cause bloating and early satiety, making it difficult for clients to consume enough calories.

3. 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.

4. What should a healthcare professional monitor for in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized redness and swelling
• C. Fever and signs of infection
• D. Loss of deep tendon reflexes

Correct answer: A

Rationale: Unrelieved pain, pallor, and pulselessness are classic signs of compartment syndrome. In this condition, increased pressure within a muscle compartment impairs blood flow, leading to severe pain that is not relieved by usual measures, pallor from decreased blood flow, and pulselessness due to compromised circulation. These signs indicate a medical emergency requiring immediate intervention. Localized redness and swelling (Choice B) are more characteristic of inflammation or infection rather than compartment syndrome. Fever and signs of infection (Choice C) are not typical manifestations of compartment syndrome. Loss of deep tendon reflexes (Choice D) is associated with conditions affecting the nervous system, not compartment syndrome.

5. After a healthcare provider misreads a glucose level and administers insulin, what is the priority intervention?

• A. Monitor for hypoglycemia
• B. Administer glucose IV
• C. Document the incident
• D. Monitor for hyperglycemia

Correct answer: A

Rationale: The correct answer is to monitor for hypoglycemia. Administering insulin based on a misread glucose level can lead to hypoglycemia. Monitoring for hypoglycemia is crucial as it is a potential adverse effect of the insulin administration. Administering glucose IV (Choice B) is not the priority as there is no indication of hypoglycemia yet. Documenting the incident (Choice C) is important but not the immediate priority over patient safety. Monitoring for hyperglycemia (Choice D) is not the priority after administering insulin in response to a misread glucose level.
