A nurse is caring for a client who consumes 3 ounces of milk, 2 ounces of orange juice, 3 ounces of tea, and 4 ounces of water over a 4-hour period. The client is also receiving dextrose 5% in 0.45% sodium chloride at a rate of 30 mL/hr by continuous IV infusion. Calculate the client’s intake for that 4-hr period in mL.

(Round the answer to the nearest whole number. Use a leading zero if it applies. DO not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["480"]

480 mL.

The client's total oral intake over the 4-hour period is 3 ounces of milk + 2 ounces of orange juice + 3 ounces of tea + 4 ounces of water = 12 ounces. Since there are approximately 30 mL in 1 ounce, the client's oral intake in mL is 12 ounces * 30 mL/ounce = 360 mL.

The client is also receiving dextrose 5% in 0.45% sodium chloride at a rate of 30 mL/hr by continuous IV infusion. Over a 4-hour period, the client will receive a total of 30 mL/hr * 4 hours = 120 mL from the IV infusion.

Therefore, the client's total intake for that 4-hour period is 360 mL (oral intake. + 120 mL (IV infusion) = 480 mL.

Correct Answer is D

Explanation

The correct answer is choice d. Begin by testing the client while they are wearing glasses. Choice A rationale: Positioning the client 3.3 meters (10 feet) away from the chart is incorrect because the standard distance for the Snellen chart is 20 feet (6 meters). Choice B rationale: Documenting the largest line the client can read on the chart is part of the procedure, but it is not the initial action the nurse should take. The nurse must first ensure the client is wearing their glasses to get an accurate assessment. Choice C rationale: Instructing the client to begin the assessment with both eyes open is incorrect because visual acuity is typically tested one eye at a time, with the other eye covered. Choice D rationale: Beginning by testing the client while they are wearing glasses is correct because it provides the most accurate assessment of the client’s visual acuity in their usual state, ensuring the glasses are effectively correcting their vision

A. Place the base of a vibrating tuning fork on the top of the client's head. B. Count how many seconds a client can hear a tuning fork after it has been struck. C. Place the base of a vibrating tuning fork on the client's mastoid process. D. Move a vibrating tuning fork in front of the client's ear canals one after the other.

Correct Answer is A

Explanation

The correct answer is that the nurse should place the base of a vibrating tuning fork on the top of the client's head when performing Weber's test. Weber's test is a screening test for hearing that can detect unilateral (one-sided. conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss)².

Options b, c and d are not correct actions for performing Weber's test. Counting how many seconds a client can hear a tuning fork after it has been struck, placing the base of a vibrating tuning fork on the client's mastoid process and moving a vibrating tuning fork in front of the client's ear canals one after the other are not part of Weber's test.
