A nurse measures a client's weight as 70 kg and height as 1.1 m. What is the client's body mass index? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Offering the client frozen banana as a snack is an appropriate intervention for the nurse to take because it can help reduce nausea and stimulate appetite. Frozen banana is cold, bland, and easy to digest, which are characteristics of antiemetic foods. Frozen banana also provides potassium, vitamin C, and fiber for the client.

Choice B reason: Serving the client hot meals is not an appropriate intervention for the nurse to take because it can worsen nausea and vomiting. Hot meals are aromatic, spicy, and greasy, which are characteristics of emetic foods. Hot meals can also irritate the stomach lining and trigger the gag reflex.

Choice C reason: Avoiding serving sauces or gravies is not an appropriate intervention for the nurse to take because it can cause dehydration and malnutrition. Sauces and gravies are liquid, mild, and moist, which are characteristics of antiemetic foods. Sauces and gravies can also enhance the flavor and texture of bland foods and provide calories and nutrients for the client.

Choice D reason: Discouraging the use of a straw is not an appropriate intervention for the nurse to take because it can prevent adequate fluid intake and hydration. Using a straw can help the client sip small amounts of clear liquids, such as water, ginger ale, or broth, which are antiemetic fluids. Using a straw can also reduce the exposure to odors and tastes that may cause nausea.

Choice A reason: Using an electronic device is not a reliable method for measuring blood pressure because it may give inaccurate readings due to movement, noise, or battery issues. An electronic device should be calibrated regularly and compared with a manual device.

Choice B reason: Inflating the cuff to 140/90 mmHg is not a correct procedure for measuring blood pressure because it may cause discomfort and false readings. The cuff should be inflated to about 20 to 30 mmHg above the expected systolic pressure or until the pulse disappears.

Choice C reason: Placing the cuff on the upper arm is a correct procedure for measuring blood pressure because it ensures that the cuff is at the same level as the heart and that the brachial artery is compressed. The cuff should be snug and fit around 80% of the arm circumference.

Choice D reason: Measuring blood pressure after exercise is not a good time for measuring blood pressure because it may reflect a temporary increase due to physical activity. Blood pressure should be measured after resting for at least 5 minutes in a quiet and comfortable environment.
