Correct Answer: B

Rationale: The correct answer is B because optimum sleep helps regulate breathing patterns during an EEG. Waking the client at midnight allows them to have a full night's rest, ensuring they are well-rested and their breathing is stable for accurate EEG results. Choice A is incorrect as excess sleep does not affect nervousness. Choice C is incorrect as waking the client does not help them fall asleep naturally during the EEG. Choice D is incorrect as headache prevention is not directly related to waking the client at midnight.

Correct Answer: D

Rationale: The correct answer is D because it offers the patient autonomy by providing a choice between brushing their teeth independently or having assistance. This empowers the patient to make decisions regarding their personal hygiene, promoting independence and self-esteem. Choice A does not offer a choice or empower the patient. Choice B focuses solely on the location of the toothbrush and does not address the patient's needs. Choice C does not provide the patient with a sense of control over their hygiene routine. By contrast, choice D acknowledges the patient's needs, offers a choice, and encourages independence.

Correct Answer: B

Rationale: The correct answer is B because nipple discharge and a breast nodule are classic signs of breast cancer. Nipple discharge can be bloody or clear, and a breast nodule is a lump that feels different from the surrounding tissue. Fever (choice A) is not a common sign of breast cancer. Breast changes during menstruation (choice C) are normal hormonal fluctuations. Fever and erythema of the breast (choice D) are more indicative of an infection rather than breast cancer. Therefore, choice B is the most relevant sign of breast cancer among the options provided.

Correct Answer: B

Rationale: The correct answer is B because providing frequent mouth care to Mr. Franco is important to remove dried blood when the tongue is bitten during a seizure. This is crucial for preventing infection and promoting oral hygiene. Choices A, C, and D are incorrect because the primary reason for mouth care in this case is to address the physical consequences of a seizure, such as tongue biting and potential injury, rather than thirst, tactile stimulation, or prevention of oral mucosal issues related to mouth breathing in a comatose patient.

Correct Answer: C

Rationale: Step-by-step rationale for choice C (Serum potassium level of 5.8 mEq/L) being the best to support a diagnosis of Addison's disease: 1. Addison's disease is characterized by adrenal insufficiency, leading to decreased aldosterone secretion. 2. Decreased aldosterone causes hyperkalemia due to impaired potassium excretion. 3. Elevated serum potassium levels above the normal range (3.5-5.0 mEq/L) are a classic finding in Addison's disease. 4. Therefore, a serum potassium level of 5.8 mEq/L strongly supports the diagnosis of Addison's disease. Summary: - Choice A (BUN level): BUN is not specific to Addison's disease and does not directly relate to adrenal function. - Choice B (Serum sodium level): Hyponatremia is a common finding in Addison's disease, but it is not as specific as hyperkalemia. - Choice D (Blood glucose level): Blood glucose
