Body temperature is one of the vital signs frequently measured in healthcare settings. Changes in a body temperature can indicate improvement or worsening of a patient's condition, so accurate measurement is important ... Read More

Handwashing is considered the single most important practice to prevent the spread of infection. Even when hands look clean, they could potentially be crawling with dangerous microorganisms and pathogens. Using soap and friction during handwashing helps loosen the oils on the skin, allowing dirt and pathogens to be rinsed away ... Read More

Respiration is a vital sign that is measured frequently in the healthcare setting. Taking this measurement requires no equipment and relatively little time. However, it is a measurement that must be taken accurately, as a change in respiration may indicate the worsening of a patient's condition ... Read More

The apical pulse rate is the most accurate non-invasive measurement of heart rate because it is measured directly over the apex of the heart. Apical pulse is preferred in cases when the radial pulse is difficult to palpate, when the pulse is irregular, greater than 100 beats per minute, or less than 60 beats per minute when measured by other means (electronic, radial, etc.) ...

The radial artery, located in the wrist, is easy to feel and an efficient location to measure heart rate. Changes to the rhythm or strength of the radial pulse can indicate heart disease, damage to the arm, or body fluid status. It is important to remember to check the radial pulse on both sides as differences between left and right can indicate injury or disease ... Read More

A tympanic membrane thermometer uses an infrared sensor to measure the temperature of the tympanic membrane (ear drum). This type of thermometer is considered an accurate and reliable predictor of a patient's core temperature because the tympanic membrane's blood supply is sourced from the carotid artery, which is the same artery that carries blood to the hypothalamus in the brain ...

A rectal temperature provides the most accurate core body temperature reading compared to other non-invasive methods. This makes a rectal temperature desirable; however, this procedure comes with more patient discomfort and more safety risks (bowel perforation, mucosal damage, and/or vagus nerve stimulation) than the other temperature measurement methods ...

Compared to other temperature measurement methods, the axillary measurement is considered the least reliable. An axillary temperature measurement typically reads 0.5 to 1 degree Fahrenheit lower than an oral temperature reading [1]. For this reason, it is recommended to use this method only when other methods are contraindicated or when taking an axillary temperature is the safest method for the patient ... Read More

Oral hygiene is about more than good breath. For patients, it can increase their sense of well-being and normalcy, as well as help ensure that they can easily consume food ... Read More

Nail care of both the feet and the hands should be performed as part of the patient's daily hygiene routine. The status of the patient's nails can reflect their overall health. Nail issues can also lead to infection that can spread systemically (ex, ingrown nails or fungus). You should never clip a patient's nails with nail clippers, and always review your institution's policy about what ... Read More
