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: C

Rationale: The correct answer is C: Risk for infection related to altered immunologic response. This is the priority nursing diagnosis for a patient preparing for hematopoietic stem cell transplant (HSCT) because the patient's immune system will be severely compromised post-transplant, leading to a high risk of infections. It is crucial to prioritize infection prevention to ensure the patient's safety and well-being. Choice A is incorrect because while fatigue is common in cancer patients, it is not the priority in this case where infection risk is higher. Choice B is incorrect as altered nutrition can be addressed after managing the risk for infection. Choice D is incorrect as body image disturbance is important but not as critical as preventing infections in this highly vulnerable patient population.

Correct Answer: D

Rationale: The correct answer is D: Personality changes. Metastases to the brain can affect cognitive function and behavior, leading to personality changes. This is due to the impact on specific areas of the brain responsible for personality and behavior. Chronic pain (A) is more commonly associated with advanced cancer and not specific to brain metastases. Respiratory distress (B) is more likely related to lung cancer itself, not brain metastases. Fixed pupils (C) may indicate brainstem involvement, but personality changes are a more direct and common manifestation of brain metastases.

Correct Answer: B

Rationale: The correct answer is B because hearing loss and tinnitus caused by aspirin are typically irreversible. Aspirin is known to cause ototoxicity, which can lead to permanent damage to the auditory system. The nurse should inform the patient that the hearing loss and tinnitus may not improve even after discontinuing aspirin. Choice A is incorrect because hearing loss caused by aspirin is usually permanent. Choice C is incorrect because aspirin is a known cause of tinnitus and hearing loss. Choice D is incorrect because tolerance to aspirin does not prevent or reverse ototoxic effects like tinnitus and hearing loss.

Correct Answer: D

Rationale: The correct answer is D, performance of pelvic muscle exercises. Pelvic muscle exercises, also known as Kegel exercises, help strengthen the pelvic floor muscles which support the bladder, uterus, and bowel. By strengthening these muscles, the risk of developing cystocele, rectocele, and uterine prolapse postpartum is reduced. It is a proactive approach to prevent these conditions. Choice A, maintenance of good perineal hygiene, is important for preventing infections but does not specifically address the risk of pelvic organ prolapse. Choice B, prevention of constipation, is also important but does not directly target the muscle weakness that contributes to prolapse. Choice C, increased fluid intake for 2 weeks postpartum, is not as effective in preventing prolapse as pelvic muscle exercises. In summary, pelvic muscle exercises are the most appropriate recommendation as they directly address strengthening the muscles that support the pelvic organs, reducing the risk of prolapse postpartum.
