Correct Answer: D

Rationale: The correct answer is D: Pallor, tachycardia, and a sore tongue. Pernicious anemia is caused by a deficiency in vitamin B12, leading to symptoms such as pallor (due to decreased red blood cells), tachycardia (as the heart works harder to compensate for decreased oxygen-carrying capacity of the blood), and a sore tongue (due to inflammation of the tongue). Choice A is incorrect because bradycardia would not be expected in pernicious anemia, and reduced pulse is not a typical finding. Choice B is incorrect because weight gain is not a common symptom of pernicious anemia. Choice C is incorrect because angina and double vision are not typical findings of pernicious anemia, and anorexia is more likely due to other causes.

Correct Answer: B

Rationale: The correct answer is B because providing frequent mouth care to Mr. Franco helps in removing dried blood when his tongue is bitten during a seizure, preventing infection and promoting oral hygiene. This is crucial in preventing complications and ensuring Mr. Franco's overall well-being. Choice A is incorrect because thirst is not directly related to mouth care, and increasing fluids intake would address dehydration more effectively. Choice C is incorrect as tactile stimulation may not necessarily hasten return to consciousness in this context. Choice D is incorrect as it refers to a different issue related to mouth breathing in comatose patients, which is not the immediate concern addressed by frequent mouth care in this scenario.

Correct Answer: D

Rationale: The correct answer is D: Diarrhea. Antibiotics can disrupt the normal balance of gut bacteria, leading to diarrhea. This occurs due to the overgrowth of harmful bacteria in the intestines. Monitoring for diarrhea is crucial to prevent dehydration and further complications. Platelet dysfunction (A), stomatitis (B), and oliguria/dysuria (C) are not typically associated with the disruption of normal flora by antibiotics. These symptoms are more likely related to other conditions or side effects of medications, making them incorrect choices in this scenario.

Correct Answer: B

Rationale: The correct answer is B because a fixed nodular mass with dimpling of the overlying skin is highly indicative of breast cancer. This finding suggests an invasive tumor pulling on the skin, causing dimpling. Other choices are incorrect because slight breast asymmetry (A) is common, bloody nipple discharge (C) can be benign or due to other conditions, and multiple freely movable masses (D) are more indicative of benign breast conditions like fibrocystic changes.

Correct Answer: B

Rationale: The correct answer is B because monitoring the site and progress of the infusion every hour is crucial to prevent complications like infiltration or infection in clients with hypertension. Choice A is incorrect as checking BP every hour is excessive. Choice C is incorrect as daily monitoring may not detect issues promptly. Choice D is incorrect as pulse rate monitoring is not directly related to IV fluid administration in this context. Monitoring the site and progress hourly ensures timely intervention if any issues arise.
