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. 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.

A. Malnutrition itself is not a direct cause of healthcare-associated infections (HAIs).
B. While having multiple caregivers can potentially increase the risk of transmission of infections if proper hand hygiene and infection control practices are not followed, it is not a direct cause of HAIs. Proper adherence to infection control protocols mitigates this risk.
C. Urinary catheterization is a common cause of healthcare-associated infections, particularly urinary tract infections (UTIs). Catheters provide a pathway for bacteria to enter the urinary tract, leading to infection if not managed properly or if left in place longer than necessary.
D. Chlorhexidine washes are actually used as an infection prevention measure rather than a cause of HAIs. Chlorhexidine is an antiseptic agent that is effective against a wide range of microorganisms and is used for preoperative skin cleansing, central line care, and other procedures to reduce the risk of infections.
