What health promotion teaching should prioritize to prevent drug-induced hepatitis?

A. Finish all prescribed courses of antibiotics, regardless of symptom resolution

B. Adhere to dosing recommendations of over-the-counter analgesics

C. Ensure that expired medications are disposed of safely

D. Ensure that pharmacists regularly review drug regimens for potential interactions

Correct Answer: B
Rationale: Adhering to dosing recommendations of over-the-counter analgesics is crucial in preventing drug-induced hepatitis. Overdosing on analgesics can lead to liver damage, making it essential to follow the recommended dosages to reduce the risk of hepatotoxicity.

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.

The nurse formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely etiology for this nursing diagnosis?

• A. Pain when coughing.
• B. Diminished cough effort.
• C. Thick, dry secretions.
• D. Excessive inflammation.

Correct Answer: B
Rationale: The correct answer is B: Diminished cough effort. Clients with myasthenia gravis often experience muscle weakness, including respiratory muscles, which can lead to diminished cough effort. This weakness can result in ineffective airway clearance, putting the client at a high risk. Pain when coughing (choice A) is not directly related to the etiology of ineffective airway clearance in myasthenia gravis. While thick, dry secretions (choice C) and excessive inflammation (choice D) can contribute to airway clearance issues, the primary concern in myasthenia gravis is the muscle weakness affecting cough effort.

A patient with peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?

• A. With meals
• B. At bedtime
• C. Before meals
• D. After meals

Correct Answer: C
Rationale: Omeprazole should be taken before meals to reduce stomach acid production and promote healing of the ulcer. Taking it before meals ensures that the medication can inhibit acid secretion when the stomach is most active in producing acid, thereby maximizing its effectiveness in treating peptic ulcer disease.

Which of the following statements is true about ischemic colitis?

• A. Typically requires colonic resection
• B. Affects the watershed areas of the colon, namely, the splenic flexure, right colon, and rectum
• C. Is only seen in the elderly
• D. Requires colonoscopic intervention

Correct Answer: B
Rationale: Ischemic colitis most often results from low-flow states associated with hypotension or poor perfusion. As a result, the vascular watershed areas of the colon, including the splenic flexure, right colon, and rectum, are at highest risk of ischemic injury. Therefore, option B is correct as it accurately identifies the areas commonly affected by ischemic colitis.
