A nurse is reinforcing teaching with a client about how to perform a breast self exam (BSE). The nurse should identify which of the following findings as an indication of breast cancer?

Choice A reason: This is an incorrect action, because emptying the drainage container every 4 hr is not necessary and can interfere with the accurate measurement of the drainage volume. The drainage container should be emptied only when it is full or at the end of the shift.

Choice B reason: This is an incorrect action, because changing the client's insertion-site dressing each shift can increase the risk of infection and dislodgment of the chest tube. The insertion-site dressing should be changed only when it is soiled or loose.

Choice C reason: This is an incorrect action, because clamping the chest tube when the client is ambulating can cause a tension pneumothorax, which is a life-threatening complication of chest tube insertion. The chest tube should be clamped only when ordered by the provider or when changing the drainage system.

Choice D reason: This is the correct action, because placing the drainage unit below the client's chest level can facilitate the drainage of air and fluid from the pleural space by gravity. The drainage unit should be kept below the client's chest level at all times.

Choice A reason: Unilateral weakness is an incorrect finding, because it is more indicative of a stroke or a brain tumor than encephalitis. Encephalitis is an inflammation of the brain that can cause neurological symptoms, but they are usually bilateral and symmetrical.

Choice B reason: Stiff neck is a correct finding, because it is a sign of meningeal irritation, which can occur in encephalitis due to the involvement of the meninges (the membranes that cover the brain and spinal cord).

Choice C reason: Photophobia is a correct finding, because it is another sign of meningeal irritation, which can cause sensitivity to light and sound.

Choice D reason: Epigastric pain is an incorrect finding, because it is not related to encephalitis. Epigastric pain is more likely to be caused by a gastrointestinal disorder, such as gastritis or peptic ulcer.

Choice E reason: Lethargy is a correct finding, because it is a sign of altered mental status, which can occur in encephalitis due to the damage to the brain tissue.
