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: A

Rationale: The correct answer is A: Provide positive feedback when he uses the word correctly. In individuals with expressive aphasia, positive reinforcement helps improve communication skills. Praising Mr. Reyea when he uses words correctly encourages continued effort and boosts confidence. This approach motivates him to communicate more despite his challenges. Summary of other choices: B: Waiting indefinitely for Mr. Reyea to verbally state needs is not practical and may lead to frustration. C: Suggesting permanent help at home assumes the disability cannot improve, which is not necessarily true for expressive aphasia. D: Helping the family to accept Mr. Reyea's inability to communicate verbally may hinder his progress and limit his social interactions.

Correct Answer: A

Rationale: The correct answer is A: Prostate-specific antigen, which is used to screen for prostate cancer. PSA is a protein produced by the prostate gland, and elevated levels may indicate prostate cancer. Choice B is incorrect as PSA is specific to the prostate, not protein levels. Choice C is incorrect as pneumococcal strep antigen is related to pneumonia, not PSA. Choice D is incorrect as Papanicolua-specific antigen is not a recognized term, and PSA is not used to screen for cervical cancer.

Correct Answer: B

Rationale: The correct answer is B: Use two people to assist the patient. This is the safest option as it provides optimal support and stability for the patient during their first postoperative ambulation. Two people can help prevent falls, ensure proper body mechanics, and offer immediate assistance if needed. Using one person (choice A) may not provide enough support. Encouraging the patient to "dangle" (choice C) may increase the risk of orthostatic hypotension. Giving a narcotic before ambulation (choice D) can impair the patient's balance and coordination, increasing the risk of falls.

Correct Answer: B

Rationale: Severe and extensive hemolysis leads to the release of large amounts of hemoglobin into the bloodstream, causing hemoglobinemia. This can result in hemoglobinuria, leading to acute renal failure and ultimately shock. Shock is the correct answer as it is a severe consequence of extensive hemolysis. Leg ulcers (A) may occur in conditions like peripheral arterial disease. Priapism (C) is unrelated to hemolysis. Compromised growth (D) is not a common consequence of hemolysis.
