Correct Answer: D

Rationale: The correct answer is D: Mobility. A malignant breast tumor typically lacks mobility due to its fixed attachment to surrounding tissues. This characteristic is concerning for malignancy as it suggests invasive growth. Incorrect answers: A: Nontenderness - Tenderness does not reliably indicate malignancy or benignancy. B: A size of 5 mm - Tumor size alone does not determine malignancy. C: Softness and a regular shape - Malignant tumors are often firm and irregular in shape.

Correct Answer: D

Rationale: The correct answer is D: Bacteria. In a patient with a urinary tract infection (UTI), bacteria are typically present in the urine due to the infection of the urinary system. Bacteria may be detected through urine culture or microscopic examination. A: Casts are not typically associated with UTIs but can indicate kidney disease. B: Protein in the urine can indicate kidney damage or other issues, not specific to UTIs. C: Crystals in the urine can be normal or indicate specific conditions, but they are not specific to UTIs. In summary, the presence of bacteria in the urine is a key indicator of a UTI, while the other choices are more indicative of different conditions or factors.

Correct Answer: A

Rationale: The correct answer is A: Ewald tube. This tube is used for gastric lavage due to its large diameter and open end which allows for effective suction of gastric contents. The Ewald tube is specifically designed for gastric lavage and is ideal for removing toxins from the stomach. Summary of why the other choices are incorrect: B: Dobhoff tube is a small-bore feeding tube, not suitable for gastric lavage. C: Miller-Abbott tube is used for intestinal decompression, not gastric lavage. D: Sengstaken-Blakemore tube is used for esophageal varices, not gastric lavage.

Correct Answer: B

Rationale: The correct answer is B: Healers. In the ETHNIC mnemonic, "H" stands for Healers, where the nurse assesses the individual's traditional healers, healthcare practices, and preferences for seeking healthcare. This is important in understanding the individual's cultural beliefs and practices related to health and treatment. Assessing "Health" (A) may be important, but it does not specifically address traditional healers. "History" (C) focuses on the individual's cultural background rather than healthcare practices. "Homeland" (D) pertains to the individual's place of origin, which is not directly related to healthcare communication.

Correct Answer: B

Rationale: The correct answer is B because in Goodpasture syndrome, the patient's immune system mistakenly targets normal constituents of the body, specifically the basement membrane of the kidneys and lungs. This autoimmune response leads to inflammation and damage in these organs, resulting in respiratory and renal dysfunction. Choice A is incorrect as immune complexes are not the primary mechanism in Goodpasture syndrome. Choice C is incorrect as it refers to T cell-mediated immune responses, which are not the main drivers in this condition. Choice D is incorrect as histamine release and cell lysis are not the main processes involved in Goodpasture syndrome.
