Choice A rationale

Hyperactive reflexes are not typically associated with hypokalemia. Hypokalemia, or low potassium levels in the blood, can cause muscle weakness, fatigue, constipation, and arrhythmia.

Choice B rationale

Extreme thirst is not a typical symptom of hypokalemia. It is more commonly associated with conditions such as diabetes.

Choice C rationale

A weak, irregular pulse is a common symptom of hypokalemia. Low levels of potassium can affect heart function, leading to abnormal heart rhythms.

Choice D rationale

Hyperactive bowel sounds are not typically associated with hypokalemia. In fact, constipation is a common symptom of this condition.

Choice A rationale

Performing hand hygiene frequently and consistently is the most effective way to prevent the spread of pathogens during patient care. Hand hygiene is the single most important measure to reduce the transmission of harmful germs and prevent health care-associated infections.

Choice B rationale

Properly disposing of contaminated equipment is important in preventing the spread of pathogens, but it is not the most effective measure. While it is crucial to handle and dispose of contaminated equipment properly, hand hygiene is the most effective measure in preventing the spread of pathogens.

Choice C rationale

Discarding used syringes in appropriate containers is a standard safety measure in healthcare settings, but it is not the most effective way to prevent the spread of pathogens during patient care. While it is important for preventing needlestick injuries and the spread of bloodborne pathogens, hand hygiene is the most effective measure in preventing the spread of pathogens.

Choice D rationale

Changing soiled linens daily for patients with draining wounds is a part of standard wound care and infection control, but it is not the most effective way to prevent the spread of pathogens during patient care. Hand hygiene remains the most effective measure in preventing the spread of pathogens.
