A nurse is completing an 8-hour intake and output (I&O) record for a client who consumed 4 oz juice, 6 oz hot tea, 100 mL ice chips, an IV bolus of 150 mL, and 8 oz broth. The nurse should record how many mL of intake on the client's record?
600 mL
740 mL
800 mL
900 mL
None
None
The Correct Answer is B
Choice A reason:
Calculating the total intake includes converting ounces to milliliters and adding all fluid intakes. 4 oz juice equals 120 mL, 6 oz hot tea equals 180 mL, ice chips are counted as half their volume, so 100 mL ice chips equals 50 mL, 150 mL IV bolus, and 8 oz broth equals 240 mL. Adding these up: 120 + 180 + 50 + 150 + 240 = 740 mL. Choice A, 600 mL, underestimates the total intake, excluding necessary details in the calculation.
Choice B reason:
Let’s calculate step by step:
-
Juice: 4 oz × 30 mL = 120 mL
-
Tea: 6 oz × 30 mL = 180 mL
-
Ice chips: 100 mL × 0.5 = 50 mL (since only half of the volume of ice is counted as fluid)
-
IV bolus: 150 mL
-
Broth: 8 oz × 30 mL = 240 mL
Now add them:
120 + 180 + 50 + 150 + 240 = 740 mL
Choice C reason:
800 mL inaccurately inflates the total intake. Accurate calculation yields 740 mL as the total fluid intake, considering all conversions and additions. Choice C misrepresents this value.
Choice D reason:
900 mL is another overestimate. Proper conversion and summation of all fluids indicate the total intake is 740 mL. Choice D is significantly higher than this calculated total, demonstrating the importance of precise conversion and addition for accurate records.

Correct Answer is B
Explanation
Choice A reason:
Client history of hypertension is not a contraindication for propofol (Diprivan) use. Propofol is primarily metabolized in the liver and excreted by the kidneys. It is generally well tolerated by most patients, including those with hypertension. Hypertension, however, is a condition that needs careful monitoring when using any anesthetic, as anesthesia can sometimes cause changes in blood pressure. This choice might be distracting because patients with hypertension require close monitoring, but it is not a specific contraindication.
Choice B reason:
Allergies to egg or soy products are a significant contraindication for the use of propofol. Propofol is formulated in a lipid emulsion that contains soybean oil and egg lecithin. Patients with known allergies to eggs or soy products may have a hypersensitivity reaction to propofol. Therefore, it is crucial for the nurse to assess for these allergies before administering the medication. This answer directly addresses the specific content of propofol and potential allergenic ingredients.
Choice C reason:
An allergy to latex is not directly relevant to the use of propofol. While latex allergies are important to identify in a clinical setting to avoid exposure to latex-containing medical supplies, they do not contraindicate the use of propofol. Propofol itself does not contain latex, and thus this choice does not address a specific contraindication for the drug in question.
Choice D reason:
The statement that propofol has no contraindications is incorrect. Like any medication, propofol has contraindications that need to be considered before administration. Allergies to its components, specifically egg and soy products, are known contraindications. This choice is misleading as it overlooks these critical factors.
Correct Answer is C
Explanation
Choice A reason:
A simple face mask provides moderate oxygen concentrations but lacks a one-way valve. It is suitable for delivering oxygen but does not meet the requirement for the highest concentration of oxygen with a one-way valve, which is crucial for preventing rebreathing of exhaled air.
Choice B reason:
A Venturi mask delivers precise oxygen concentrations and is useful for patients requiring controlled oxygen therapy. However, it does not provide the highest concentration of oxygen and does not have a one-way valve system to prevent rebreathing.
Choice C reason:
A non-rebreather mask is designed to deliver the highest concentration of oxygen available in a mask system. It includes a reservoir bag and a one-way valve that prevents exhaled air from mixing with the oxygen in the bag, ensuring that the client receives nearly 100% oxygen concentration.
Choice D reason:
A partial rebreather mask delivers high oxygen concentrations but allows some rebreathing of exhaled air due to the absence of a one-way valve. It is not the best choice for providing the highest concentration of oxygen with a one-way valve, which is necessary for certain medical conditions.
