Correct Answer: C

Rationale: Patients with a history of peptic ulcer disease should avoid Nonsteroidal anti-inflammatory drugs (NSAIDs) because they can worsen peptic ulcers due to their effects on the stomach lining. Acetaminophen (Choice A) is a safer alternative for pain relief in such patients as it does not have the same ulcerogenic effects. Antacids (Choice B) can actually help alleviate symptoms by neutralizing stomach acid and are generally safe to use. Antihistamines (Choice D) are not known to exacerbate peptic ulcers and can be used safely for conditions like allergies.

Correct Answer: A

Rationale: The correct answer is A: 'Managing patients' legal affairs.' Practical nurse management responsibilities are typically categorized into managing work center operations, managing personnel, and overseeing patient care. Legal affairs management is not a standard responsibility for practical nurse management. Choice B is incorrect as it introduces information about the hypothalamus, which is unrelated to the question. Choice C and D are both common areas of concern in practical nurse management, involving the operations of the work center and managing personnel, respectively.

Correct Answer: A

Rationale: The correct answer is A: Stomach irritation and bleeding. Nonsteroidal anti-inflammatory drugs (NSAIDs) can lead to stomach irritation and bleeding by affecting the gastric mucosa. Stomatitis and esophagitis (choice B) are not commonly associated with NSAIDs. Impaired folate absorption (choice C) is not a typical side effect of NSAIDs. Increased potassium excretion (choice D) is not a common side effect of NSAIDs.

Correct Answer: C

Rationale: Patients with a history of peptic ulcer disease should avoid nonsteroidal anti-inflammatory drugs (NSAIDs) because they can worsen peptic ulcers. NSAIDs inhibit the production of prostaglandins, which help protect the stomach lining. Acetaminophen (Choice A) is a safer alternative for pain relief in patients with peptic ulcers. Antacids (Choice B) can actually help in symptom relief by neutralizing stomach acid. Antihistamines (Choice D) are not known to worsen peptic ulcers and are generally safe for use in patients with this condition.

Correct Answer: B

Rationale: The correct first step in providing health care for a patient is to determine the needs of the patient. Understanding the patient's requirements, concerns, and medical history is crucial before proceeding with any further steps. Option A, 'Obtain and interpret vital signs,' may be necessary but typically follows assessing the patient's needs. Option C, 'Develop a plan of care,' comes after identifying the patient's needs. Option D, 'Obtain lab work and x-rays,' is usually done based on the patient's needs and the developed plan of care, making it a later step in the process.
