Which of the following are the main types of functional headaches? Select all that apply.

Choice A reason: Screening for metastasis is not typically necessary for BCC because it rarely metastasizes.

Choice B reason: Minimizing sun exposure is crucial in reducing the risk for future BCC, as UV radiation is a significant risk factor.
Choice C reason: Watchful waiting is not a standard treatment plan for BCC; treatment usually involves removal of the lesion.
Choice D reason: Low-dose systemic chemotherapy is generally not used to treat BCC; local treatments such as surgery or topical medications are preferred.

Choice A reason: Taking several deep breaths is not specifically related to the preparation for a renal system physical assessment. Deep breaths are more commonly associated with lung examination or to help the patient relax.

Choice B reason: Drinking several glasses of water before a renal assessment could potentially fill the bladder, which might interfere with palpation of the kidneys and make it uncomfortable for the patient.

Choice C reason: Emptying the bladder is the correct action before a renal system physical assessment. It allows for better palpation of the kidneys and other structures without the discomfort of a full bladder. It also prevents the possibility of the patient urinating involuntarily during the examination due to a full bladder.

Choice D reason: Providing a urine sample might be part of the overall renal assessment, but it is not necessary to do so immediately before the physical examination of the renal system. The sample can be collected at any time before or after the physical examination.
