A nurse is preparing to administer olanzapine 10 mg PO. Available is olanzapine 5 mg orally disintegrating tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Gloves are not specifically required for airborne precautions unless contact with infectious secretions or materials is anticipated. Airborne precautions primarily focus on preventing inhalation of infectious droplet nuclei. Therefore, wearing gloves is not necessary solely due to airborne precautions.
B. This option is not related to airborne precautions. Encouraging ambulation in the hall is a general nursing intervention and does not specifically address preventing the transmission of airborne pathogens.
C. An N95 respirator mask is designed to filter out 95% of airborne particles, including those containing infectious agents. It provides respiratory protection for healthcare workers who may be exposed to airborne pathogens during procedures such as aerosol-generating procedures (e.g., suctioning, bronchoscopy) or when caring for clients with airborne infections.
D. Positive pressure airflow rooms are typically used for clients requiring protective isolation (e.g., immunocompromised clients) but are not specifically required for clients on airborne precautions. Negative pressure airflow rooms are preferred for clients on airborne precautions because they prevent the spread of airborne pathogens to other areas of the facility.

A. Positioning the client's arm above heart level can result in a falsely low blood pressure reading. This is because gravity assists in the flow of blood downward, artificially reducing the pressure measured in the arteries. For accurate blood pressure measurement, the client's arm should be positioned at heart level or slightly below heart level.
B. If the blood pressure cuff is wrapped too loosely around the client's arm, it can lead to inaccurate readings. A loose cuff may allow leakage of air during inflation or may not provide sufficient compression to accurately detect the arterial pressure pulses.
C. Deflating the cuff too slowly can cause a falsely high diastolic pressure reading. When the cuff is deflated slowly, the pressure in the cuff remains close to the systolic pressure for a longer duration, leading to incorrect readings, especially in diastolic pressure.
Blood pressure can temporarily increase after meals due to digestion, particularly in clients with hypertension. Measuring blood pressure immediately after a meal may result in a higher reading that does not reflect the client's baseline blood pressure. However, this would typically lead to a higher reading rather than a lower one.
