Nursing Elites

1. A 45-year-old obese man arrives at a clinic reporting daytime sleepiness, difficulty falling asleep at night, and snoring. The nurse should recognize the manifestations of what health problem?

• A. Adenoiditis
• B. Chronic tonsillitis
• C. Obstructive sleep apnea
• D. Laryngeal cancer

Correct answer: C

Rationale: The symptoms described, including daytime sleepiness, difficulty falling asleep at night, and snoring, are classic signs of obstructive sleep apnea. This condition is commonly seen in obese individuals due to the relaxation of throat muscles during sleep, leading to airway obstruction. Adenoiditis and chronic tonsillitis are less likely as they don't typically present with the same symptoms mentioned.

2. What is the primary action of a short-acting beta2-agonist (SABA) prescribed to a patient with an acute asthma exacerbation?

• A. Reduce inflammation
• B. Relieve bronchospasm
• C. Thin respiratory secretions
• D. Suppress cough

Correct answer: B

Rationale: The correct answer is B: Relieve bronchospasm. The primary action of short-acting beta2-agonists (SABAs) is to relieve bronchospasm. These medications are bronchodilators that work by opening the airways, making breathing easier for patients experiencing asthma exacerbations. By relieving bronchospasm, SABAs help improve airflow and alleviate symptoms of asthma such as wheezing and shortness of breath. Choices A, C, and D are incorrect because SABAs do not primarily reduce inflammation, thin respiratory secretions, or suppress cough. While these actions may be part of asthma management, the immediate goal of using a SABA during an acute exacerbation is to quickly relieve bronchospasm and improve airflow.

3. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.

4. The nurse is planning care for a client with cirrhosis of the liver. Which intervention should the nurse include to reduce the risk of bleeding?

• A. Monitor for signs of infection.
• B. Limit the client's dietary protein intake.
• C. Administer vitamin K as prescribed.
• D. Encourage the client to increase fluid intake.

Correct answer: C

Rationale: Administering vitamin K as prescribed can help reduce the risk of bleeding in clients with cirrhosis by promoting clotting factor production. Cirrhosis often leads to impaired liver function, affecting the synthesis of clotting factors. Vitamin K supplementation helps in the production of these essential clotting factors, thus reducing the risk of bleeding in clients with cirrhosis. Monitoring for signs of infection (Choice A) is important for overall care but not directly related to reducing the risk of bleeding in cirrhosis. Limiting dietary protein intake (Choice B) may be necessary in some cases of cirrhosis but does not directly address the risk of bleeding. Encouraging increased fluid intake (Choice D) is beneficial for various aspects of health but does not specifically target the risk of bleeding in cirrhosis.

5. What should be monitored to evaluate the effectiveness of enoxaparin in a patient with deep vein thrombosis (DVT)?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: C

Rationale: The international normalized ratio (INR) is the appropriate parameter to monitor the effectiveness of enoxaparin in preventing clot formation in patients with deep vein thrombosis (DVT). INR reflects the clotting ability of the blood and is commonly used to assess the therapeutic range of anticoagulant medications, such as enoxaparin, which is crucial in managing and preventing thrombotic events like DVT.
