Correct Answer: D

Rationale: The correct answer is D: Men can develop breast cancer. This is accurate because although breast cancer is more common in women, men can also develop the disease due to the presence of breast tissue in their bodies. This is a crucial point to emphasize to raise awareness about breast cancer among men. Incorrect choices: A: Mammography is not the most reliable method for detecting breast cancer, as it may not detect all types of breast cancer. B: Breast cancer is not the leading killer of women of childbearing age, as there are other leading causes of death in this age group. C: Breast cancer does not always require a mastectomy; treatment options vary depending on the individual case. Summary: Choice D is correct as it highlights the important fact that men can also develop breast cancer, which is often overlooked. Choices A, B, and C are incorrect due to inaccuracies or oversimplifications of the facts related to breast cancer detection, statistics, and treatment.

Correct Answer: B

Rationale: The correct answer is B: To carry out the plan of care. In the nursing process, implementation is the phase where nurses put the established care plan into action by delivering the interventions outlined to meet the client's needs. This step is crucial as it ensures that the care plan is executed effectively and efficiently. Establishing priorities (A) is done during the planning phase, identifying client outcomes (C) is part of the evaluation phase, and validating nursing diagnoses (D) is typically done during the assessment phase, not implementation.

Correct Answer: B

Rationale: The correct answer is B: Wear sunglasses. Dilated pupils are sensitive to light, so wearing sunglasses can help protect the eyes from excessive light exposure. Keeping the eyes closed (A) may provide temporary relief but does not protect the eyes from light. Avoiding driving for 8 hours (C) is important after certain eye procedures but not specifically related to dilated pupils. Avoiding caffeinated beverages (D) is unrelated to pupil dilation.

Correct Answer: C

Rationale: The correct answer is C: severe, unrelieved pain. Compartment syndrome is characterized by increased pressure within a muscle compartment leading to decreased blood flow and tissue damage. Severe, unrelieved pain is a hallmark sign as the pressure builds up. Weak movement of the patient's toes (choice A) could indicate nerve damage but is not specific to compartment syndrome. Decreased pedal pulses (choice B) could suggest vascular compromise but are not specific to compartment syndrome. Presence of foot pallor (choice D) could indicate poor circulation but is not a definitive sign of compartment syndrome.

Correct Answer: D

Rationale: Step 1: Multiple sclerosis (MS) is a progressive disease affecting the central nervous system. Step 2: Axon degeneration occurs in MS, leading to impaired nerve signal transmission. Step 3: MS is characterized by sclerosed patches, or plaques, in the nervous system. Step 4: Demyelination of the brain and spinal cord is a hallmark feature of MS. Step 5: Therefore, all of the above choices are correct as they accurately describe key features of MS.
