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 an escharotomy, and why is it performed?

• A. To relieve pressure and improve circulation in burn injuries
• B. To reduce pain in the affected area
• C. To remove necrotic tissue from a wound
• D. To remove fluid from a burn wound

Correct answer: A

Rationale: An escharotomy is a surgical procedure performed to relieve pressure and improve circulation in areas affected by deep burns. Choice A is the correct answer because the primary goal of an escharotomy is to prevent compartment syndrome caused by increased pressure within the affected tissues. Choices B, C, and D are incorrect because an escharotomy is not primarily performed to reduce pain, remove necrotic tissue, or drain fluid from a burn wound, but to address the specific issue of compromised blood flow and pressure within deep burn injuries.

3. A nurse misreads a glucose reading and administers insulin for a blood glucose of 210 instead of 120. What should the nurse monitor the patient for?

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

Correct answer: B

Rationale: The correct answer is B: Monitor for signs of hypoglycemia. The nurse should monitor the patient for hypoglycemia due to the administration of excess insulin. Administering insulin for a blood glucose level of 210 instead of 120 can lead to a rapid drop in blood sugar levels, causing hypoglycemia. Option A is incorrect as hyperglycemia is high blood sugar, which is unlikely in this scenario. Option C is incorrect as administering glucose IV would worsen the hypoglycemia. Option D is not the immediate priority; patient safety and monitoring for adverse effects take precedence.

4. A nurse misreads a blood glucose level and administers excess insulin. What should the nurse monitor for?

• A. Monitor for hyperglycemia
• B. Monitor for hypoglycemia
• C. Administer glucose IV
• D. Monitor for increased thirst

Correct answer: B

Rationale: The correct answer is to monitor for hypoglycemia. Excess insulin can lead to low blood glucose levels, causing hypoglycemia. Symptoms of hypoglycemia include sweating, trembling, dizziness, confusion, and in severe cases, loss of consciousness. Options A, C, and D are incorrect because administering excess insulin would not lead to hyperglycemia or increased thirst, and administering glucose IV would exacerbate the issue by further lowering blood glucose levels.

5. 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.
