Correct Answer: C

Rationale: The correct initial action for the nurse is to choose option C: Notify the physician. Increasing oxygen without a healthcare provider's order can be harmful, especially in COPD patients prone to retaining carbon dioxide. The nurse should communicate the situation to the physician to assess the client's condition and adjust the oxygen therapy appropriately. Option A is incorrect as it neglects the potential risks of high oxygen levels. Option B is incorrect as immediate decrease without proper assessment can be dangerous. Option D is not the priority when the client's oxygen therapy needs evaluation.

Correct Answer: D

Rationale: The correct answer is D because systemic lupus erythematosus can lead to inflammation in the lungs, causing abnormal lung sounds. Dysphagia (choice A) is not typically associated with lupus. Dryness or itching of genitalia (choice B) is more characteristic of conditions like yeast infections or dermatitis. Decreased visual acuity or blindness (choice C) is not a common manifestation of lupus. Abnormal lung sounds (choice D) are commonly seen in lupus patients due to inflammation and possible lung involvement.

Correct Answer: D

Rationale: The correct answer is D: Eight Cranial Nerve (Vestibulocochlear). This nerve is responsible for hearing and balance. Ringing noises indicate a disturbance in hearing function. The other choices are incorrect because: A: Frontal lobe is associated with executive functions, not hearing. B: Six cranial nerve (abducent) controls eye movement. C: Occipital lobe is related to vision, not hearing. Therefore, the correct choice is D as it directly relates to the symptom described.

Correct Answer: A

Rationale: Rationale: A: Diphenhydramine hydrochloride (Benadryl) is an antihistamine commonly used to treat allergic reactions, including those from bee stings. It can help alleviate symptoms like itching and swelling. Keeping Benadryl on hand is crucial for managing an allergic reaction promptly. Other Choices: B: Guaifenesin (Robitussin) is an expectorant used to treat coughs, not allergic reactions. C: Pseudoephedrine hydrochloride (Sudafed) is a decongestant used for nasal congestion, not allergic reactions. D: Loperamide (Imodium) is an antidiarrheal used to treat diarrhea, not allergic reactions.

Correct Answer: B

Rationale: The correct answer is B: helicobacter pylori infection. This bacterium is a major cause of peptic ulcers by weakening the protective mucous layer of the stomach and duodenum. Research has shown a strong association between H. pylori infection and peptic ulcer development. Genetic defects in the gastric mucosa (choice A) are not a proven cause of peptic ulcers. While a high-fat diet (choice C) can exacerbate symptoms, it is not the primary cause. Work-related stress (choice D) may exacerbate symptoms but is not a direct cause of peptic ulcers. Therefore, choice B is the most supported and logical answer based on current research findings.
