The MD orders a pre-op patient to have Kefzol 1g to be infused over 15 minutes.

The Kefzol is diluted in 50 mL of D5W.

How many milliliters per hour will the nurse infuse the drug?

Choice A rationale

Memory loss is more commonly associated with neurological conditions, vitamin B12 deficiency, or aging, rather than a lack of dietary fiber. Fiber primarily affects the digestive system and blood sugar control, not cognitive function.

Choice B rationale

Bleeding gums are typically a sign of vitamin C deficiency (scurvy) or poor oral hygiene leading to gingivitis. While overall nutrition is important for oral health, a lack of fiber specifically does not directly cause bleeding gums.

Choice C rationale

Brittle hair can be a symptom of various nutritional deficiencies, including protein, biotin, and iron, but it is not a primary indicator of inadequate fiber intake. Fiber mainly impacts bowel function and glucose metabolism.

Choice D rationale

Constipation, characterized by infrequent or difficult bowel movements, is a well-established consequence of inadequate dietary fiber intake. Fiber adds bulk to the stool, absorbs water, and facilitates peristalsis, the muscular contractions that move stool through the intestines. A lack of fiber can lead to harder, drier stools that are more difficult to pass. .

Choice A rationale

Hyperresonance is a booming sound elicited during percussion, typically heard over hyperinflated lung tissue, such as in emphysema or pneumothorax. In the abdominal assessment, hyperresonance is generally not an expected finding and may indicate gaseous distension.

Choice B rationale

Flatness is a dull, very soft sound with a short duration, usually heard over dense tissues such as bone or muscle. In the abdomen, flatness is not a typical percussion sound and might be elicited over a large tumor or organomegaly.

Choice C rationale

Dullness is a thud-like sound with a medium intensity and duration, typically heard over solid organs such as the liver, spleen, or a distended bladder. In the abdominal assessment, dullness is an expected finding over these organs.

Choice D rationale

Resonance is a hollow sound of moderate duration and low pitch, typically heard over normal lung tissue. Resonance is not an expected percussion sound in the abdominal assessment; tympany and dullness are the predominant sounds.

Choice E rationale

Tympany is a drum-like sound with high pitch and longer duration, commonly heard over air-filled structures such as the stomach and intestines. Tympany is the predominant percussion sound expected over most of the abdomen due to the presence of gas in the gastrointestinal tract.
