Correct Answer: C

Rationale: The correct answer is C: positive wound cultures. Osteomyelitis is an infection of the bone that is typically diagnosed through wound cultures. This assessment helps to identify the causative organism and guide appropriate treatment. Choices A and D are not typical findings in osteomyelitis. Choice A describes symptoms of poor circulation which are not specific to osteomyelitis. Choice B, decreased white blood cell count, is typically not seen in the presence of an infection like osteomyelitis.

Correct Answer: B

Rationale: The correct answer is B because after developing a plan of care, the nurse must communicate it to all healthcare professionals involved in the patient's care to ensure everyone is aware of the plan and can collaborate effectively. This promotes continuity of care and prevents errors. Choice A is incorrect because the plan of care should not be placed in the chart to avoid tampering; it should be easily accessible for updates. Choice C is incorrect as filing in the administration office is unnecessary for routine care. Choice D is incorrect as sending the plan to quality assurance is not the immediate next step after developing the plan.

Correct Answer: B

Rationale: The correct answer is B because it directly reflects the client's progress in physical activity, a key indicator of recovery post-myocardial infarction. Walking 500 meters without chest pain shows improved cardiovascular function and exercise tolerance. Vital signs and lab results from admission (A) are important for initial assessment but not for ongoing evaluation. Physician notes (C) may provide insights but do not directly measure the client's progress. Medications prescribed (D) are important but do not reflect the client's specific improvement in physical activity.

Correct Answer: B

Rationale: The correct answer is B: Altered level of consciousness. This is crucial as it can indicate various underlying health issues affecting Mr. Reyes. Assessing for this helps in detecting potential neurological, metabolic, or cardiac issues. A: Decreased carotid pulses - While important, it is not as critical as altered level of consciousness in this scenario. C: Bleeding from oral cavity - This is important to address but does not take priority over assessing Mr. Reyes' level of consciousness. D: Absence of deep tendon-reflexes - This is more specific to neurological assessments and may not be as urgent as assessing his level of consciousness.

Correct Answer: B

Rationale: The correct answer is B: 45-year old woman who has never been pregnant. The risk of ovarian cancer increases with age and nulliparity (never having been pregnant) is a significant risk factor. The older a woman gets without having been pregnant, the higher her risk of developing ovarian cancer. The other choices do not have as high of a risk factor for ovarian cancer. Choice A, a 30-year old woman taking contraceptives, actually reduces the risk of ovarian cancer. Choice C, a 40-year old woman with three children, and choice D, a 36-year old woman who had her first child at age 22, both have lower risk factors compared to choice B.
