Nursing Elites

1. 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.

2. What is the purpose of an escharotomy in burn management?

• A. To relieve pressure and improve circulation in burn injuries
• B. To remove necrotic tissue from a wound
• C. To prevent infection in burn injuries
• D. To remove excess fluid from burn wounds

Correct answer: A

Rationale: An escharotomy is performed to relieve pressure in areas affected by deep burns and improve circulation. This procedure involves making incisions through the eschar (burned and dead tissue) to release constricting tissue and allow for the return of blood flow. Choice B is incorrect because the removal of necrotic tissue is typically done through debridement, not escharotomy. Choice C is incorrect because preventing infection in burn injuries is usually achieved through proper wound care and antibiotic therapy, not escharotomy. Choice D is incorrect because removing excess fluid from burn wounds is managed through methods like fluid resuscitation and monitoring, not escharotomy.

3. What ECG changes are associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: Hyperkalemia is known to cause ST depression on an ECG. Flattened T waves are more commonly seen in hypokalemia. Prominent U waves are associated with hypokalemia rather than hyperkalemia. Elevated ST segments are not typical findings in hyperkalemia.

4. What should be monitored for in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized redness and swelling
• C. Fever and infection
• D. Muscle weakness and fatigue

Correct answer: A

Rationale: Correct Answer: A. Unrelieved pain, pallor, and pulselessness are classic signs of compartment syndrome that indicate inadequate blood flow to the affected area. These symptoms are crucial to monitor as they signify a medical emergency requiring immediate intervention. Choices B, C, and D are incorrect because they do not align with the typical manifestations of compartment syndrome. Localized redness and swelling may be present but are not the primary indicators. Fever and infection are also not specific to compartment syndrome, and muscle weakness and fatigue are not typically prominent symptoms of this condition.

5. A patient is admitted with chest pain, possible acute coronary syndrome. What should the nurse do first?

• A. Administer sublingual nitroglycerin
• B. Get IV access
• C. Obtain cardiac enzymes
• D. Auscultate heart sounds

Correct answer: A

Rationale: In a patient with chest pain, possible acute coronary syndrome, the nurse should administer sublingual nitroglycerin first. Nitroglycerin helps to vasodilate coronary arteries, improving blood flow to the heart, and reducing cardiac workload. This can alleviate chest pain and decrease cardiac tissue damage in acute coronary syndrome. Getting IV access, obtaining cardiac enzymes, and auscultating heart sounds are important steps in the assessment and management of acute coronary syndrome, but administering nitroglycerin to relieve chest pain and improve blood flow takes precedence as it directly addresses the patient's symptoms and aims to prevent further cardiac damage.
