Alcohol-based sanitizer: Alcohol-based sanitizers are effective for hand hygiene when there is no visible dirt or grease. They are generally used for routine hand antisepsis in situations where hands are not visibly soiled. For procedures involving body fluids, if hands are visibly soiled, traditional handwashing with soap and water is preferred.

Disinfectant scrub: Disinfectant scrubs are generally used for cleaning surfaces and are not appropriate for personal hand hygiene.

Antiseptic solution: Antiseptic solutions are used for cleaning skin before injections or procedures, not typically for hand hygiene.

Applying powder to the site: Powder should not be applied to the site as it can interfere with electrode adhesion and signal transmission.

Taping the electrodes to the skin: Taping is not necessary if the electrodes are properly adhered with the adhesive backing. Excessive taping could cause discomfort or interfere with the electrode function.

Allowing the electrodes to sit for several hours before application: Electrodes should be applied immediately after preparation. Allowing them to sit for an extended period is not necessary and does not improve the quality of the EKG.

Exaggerate lip movements. Exaggerating lip movements can make speech more difficult to understand. Instead, normal, clear speech should be used.

Speak in high-pitched tones. High-pitched tones are often harder for individuals with hearing loss to understand. Speaking in a normal, moderate tone is more effective.

Use long sentences. Long sentences can be confusing. It is better to use short, simple sentences to aid comprehension.

Have the patient hold on to the wall while weighing. Holding onto the wall can be unsafe and can affect the accuracy of the weight measurement.

Position a walker over the scale. Positioning a walker over the scale can affect the scale's accuracy and the patient's balance.

Position a cane on the scale between her feet. Placing a cane on the scale can affect weight measurement and may not provide accurate results.

Heart rate: Pyrexia (fever) often leads to an increased heart rate as the body attempts to regulate its temperature. Therefore, heart rate may be higher than normal.

Respiratory rate: While fever can sometimes affect the respiratory rate, it is not as directly impacted as heart rate or temperature. Respiratory rate may be slightly elevated but is less consistently affected compared to heart rate and temperature.

Blood pressure: Fever does not typically cause significant changes in blood pressure. It is less likely to be outside the expected reference range compared to heart rate and temperature.

Performing a heel stick on an infant: This procedure is often performed by medical assistants, especially in a pediatric setting, as it is part of routine blood collection practices.

Drawing blood for a glucose tolerance test: Medical assistants are usually trained to perform blood draws, including for glucose tolerance tests.

Performing venipuncture with a winged collection device: Medical assistants are generally trained to perform venipunctures, including using winged collection devices (butterfly needles).

Label the tube after collection, including the provider's name: While it is important to include identifying information, the primary focus should be on the date and time of collection to ensure the sample's accuracy.

Label the tube prior to collection, including the date and time of collection: Labels should be applied after the collection to avoid potential errors and ensure the correct sample is labeled.

Label the tube prior to collection, including the provider's name: Labeling prior to collection may lead to mistakes if the wrong sample is placed in the labeled tube. The correct practice is to label after collection.

Posterior: "Posterior" refers to the back of the body, which is not the location of the rash in this scenario.

Lateral: "Lateral" refers to the side of the body. While the rash may be on the side of the arm, it is more specifically described as anterior.

Medial: "Medial" refers to the midline of the body, not specifically to the front of the arm.

Obtaining a tympanic reading: This procedure does not typically require gloves as it is non-invasive and does not involve contact with bodily fluids.

Performing a visual acuity test: This test is non-invasive and does not require gloves.

Removing a cyst: This procedure typically requires more than gloves; it involves aseptic technique and potentially sterile equipment. Gloves are part of the preparation but are not sufficient on their own.

Restrain the patient: Restraining a patient during a seizure can cause injury and is not recommended.

Place a tongue blade in the patient's mouth: This is a myth and can cause harm. It is not safe or effective.

Initiate CPR on the patient: CPR is not needed unless the patient does not regain consciousness after the seizure or if there are other signs of respiratory or cardiac arrest.
