Nursing Elites

1. A patient scheduled for cataract surgery asks the nurse why they developed cataracts and how to prevent it in the future. What is the nurse's best response?

• A. Age is the biggest factor contributing to cataracts.
• B. Unprotected exposure to UV lights can cause cataracts.
• C. Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.
• D. Unfortunately, there is really nothing you can do to prevent cataracts, but they are amongst the most easily treated eye conditions.

Correct answer: C

Rationale: The correct answer is C: 'Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.' This response is the best choice as it covers the most common contributing factors for cataracts and includes preventable risk factors. Choice A is incorrect because while age is a significant factor in cataract development, it is not the only one. Choice B is incorrect as UV light exposure is a risk factor for cataracts but not the most comprehensive response. Choice D is incorrect as there are preventive measures individuals can take to reduce their risk of developing cataracts, such as protecting their eyes from UV light and managing other risk factors.

2. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

3. When assessing a patient who has just arrived after an automobile accident, the emergency department nurse notes tachycardia and absent breath sounds over the right lung. For which intervention will the nurse prepare the patient?

• A. Emergency pericardiocentesis
• B. Stabilization of the chest wall with tape
• C. Administration of an inhaled bronchodilator
• D. Insertion of a chest tube with a chest drainage system

Correct answer: D

Rationale: The patient's history and absent breath sounds suggest a right-sided pneumothorax or hemothorax, which will require treatment with a chest tube and drainage. Emergency pericardiocentesis is not indicated as the patient's symptoms are not suggestive of cardiac tamponade. Stabilization of the chest wall with tape would not address the underlying issue of a potential pneumothorax or hemothorax. Administration of an inhaled bronchodilator is not appropriate in this scenario as the patient is not exhibiting signs of asthma or bronchoconstriction. Therefore, the correct intervention for this patient is the insertion of a chest tube with a chest drainage system to address the potential pneumothorax or hemothorax.

4. A patient's chart indicates a history of hyperkalemia. Which of the following would you not expect to see with this patient if this condition were acute?

• A. Decreased HR
• B. Paresthesias
• C. Muscle weakness of the extremities
• D. Migraines

Correct answer: D

Rationale: The correct answer is 'Migraines.' Migraines are not a symptom typically associated with hyperkalemia. In acute hyperkalemia, one would not expect to see migraines. Symptoms of hyperkalemia often include muscle weakness, paresthesias, and cardiac manifestations such as bradycardia or even cardiac arrest. Therefore, choices A, B, and C are more commonly associated with acute hyperkalemia compared to migraines, making it the correct choice.

5. A nurse prepares to care for a 4-year-old newly admitted for rhabdomyosarcoma. The nurse should alert the staff to pay more attention to the function of which area of the body?

• A. All striated muscles
• B. The cerebellum
• C. The kidneys
• D. The leg bones

Correct answer: A

Rationale: Rhabdomyosarcoma is the most common soft tissue sarcoma in children, originating in striated (skeletal) muscles and potentially affecting any part of the body. Symptoms vary based on the location of the tumor. In the head or neck area, symptoms may include sudden bulging or swelling of the eyes, conjunctival chemosis, and headache. Rhabdomyosarcoma can also impact organs like the urinary or reproductive system. Common metastatic sites include the lungs. Therefore, the nurse should pay attention to the function of all striated muscles in the child to monitor for any signs or symptoms related to the disease. Choices B, C, and D are incorrect as rhabdomyosarcoma primarily involves striated muscles and does not specifically target the cerebellum, kidneys, or leg bones.
