During lung auscultation, the nurse hears a continuous low-pitched sound that resembles snoring. What is this sound called?

Choice A reason: The gastrointestinal tract does not provide oxygen to organs; this is the respiratory and circulatory systems’ role, delivering oxygen via lungs and blood. The GI tract focuses on digestion, absorption, and waste elimination, making this function unrelated to its physiological responsibilities.

Choice B reason: Elimination of waste is a core gastrointestinal function, achieved through defecation. The large intestine compacts waste into feces, expelling it via the rectum, a critical process for removing indigestible material and toxins, making this a valid GI tract function.

Choice C reason: Digestion of food is a primary gastrointestinal function, involving mechanical and chemical breakdown in the stomach and small intestine. Enzymes and acids process nutrients for absorption, a fundamental GI role, making this choice a correct description of its physiological tasks.

Choice D reason: Removing water-soluble waste is a gastrointestinal function, as the colon reabsorbs water, concentrating waste for elimination. This process ensures efficient waste management, distinguishing it from renal functions, making this a valid role of the GI tract in waste handling.

Choice A reason: Pain level assessment is important but unrelated to orientation, which evaluates mental state via time, place, and person questions. Assuming pain assesses orientation risks missing cognitive deficits, delaying diagnosis of delirium or dementia, critical for tailoring care and interventions in patients with altered mental status.

Choice B reason: Personal hygiene reflects self-care ability, not orientation to time, place, or person, which assesses mental state. Assuming hygiene evaluates orientation misguides assessment, risking oversight of cognitive impairments, essential for diagnosing conditions like Alzheimer’s or acute confusion, requiring targeted interventions in clinical practice.

Choice C reason: Orientation questions assess mental state, evaluating cognitive function through awareness of time, place, and person. This detects impairments in conditions like delirium or dementia, guiding care planning. Accurate assessment ensures timely interventions, critical for managing cognitive decline and supporting patient safety and communication in healthcare settings.

Choice D reason: Family medical history provides genetic context but doesn’t assess orientation, which targets mental state. Assuming history evaluates orientation risks missing cognitive issues, delaying diagnosis of acute or chronic cognitive impairments, critical for implementing cognitive support or pharmacological interventions in patients with suspected mental status changes.
