A nurse is documenting an 8-hour intake and output (I&O) record for a patient who consumed 4 oz of juice, 6 oz of tea, a 100 mL cup of soda, an IV bolus of 150 mL, and 8 oz of broth. How many mL of intake should the nurse record on the patient’s chart?
500 mL
600 mL
700 mL
800 mL
The Correct Answer is D
The correct answer is Choice D.
Let’s go through the calculations step by step:
Step 1: Convert all the quantities to milliliters (mL), as the nurse needs to record the intake in mL. We know that 1 oz is approximately 29.5735 mL.
4 oz of juice = 4 × 29.5735 mL = 118.294 mL
6 oz of tea = 6 × 29.5735 mL = 177.861 mL 8 oz of broth = 8 × 29.5735 mL = 236.628 mL Step 2: Add all the quantities together:
118.294 mL (juice) + 177.861 mL (tea) + 100 mL (soda) + 150 mL (IV bolus) + 236.628 mL (broth) = 783.783 mL Step 3: Round off the total intake to the nearest whole number as required, which gives us 784 mL.
Therefore, the nurse should record 784 mL on the patient’s chart. However, this option is not available in the choices given. The closest option to this calculated value is 800 mL (Choice D).
Now, let’s discuss the rationales for each choice:
Choice A rationale:
500 mL would be an underestimate of the patient’s fluid intake. It does not account for all the fluids the patient consumed.
Choice B rationale:
600 mL, similar to Choice A, is an underestimate. It does not accurately represent the total volume of fluids the patient consumed. Choice C rationale:
700 mL is closer to the calculated intake but is still an underestimate. It does not fully account for all the fluids the patient consumed.
Choice D rationale:
800 mL is the closest option to the calculated intake of 784 mL. Although it’s slightly over the actual intake, it’s the best choice among the given options.

Correct Answer is B
Explanation
Choice A rationale:
Double vision is not a common side effect of quinolones. Quinolones are a type of antibiotic that are used to kill or inhibit the growth of bacteria. While they can have side effects, double vision is not typically one of them.
Choice B rationale:
Tendonitis and tendon rupture are known adverse effects of quinolones. These antibiotics can very rarely cause long-lasting, disabling, and potentially irreversible side effects, sometimes affecting multiple systems, organ classes, and senses. One of these side effects is damage to the tendons, which can manifest as tendonitis (inflammation of the tendon) or even tendon rupture. This is particularly a concern for people older than 60 years and for those with renal impairment or solid-organ transplants because they are at a higher risk of tendon injury.
Choice C rationale:
Neuralgia, or nerve pain, is not a common side effect of quinolones. While these antibiotics can affect the nervous system and cause side effects such as peripheral neuropathy and central nervous system effects, neuralgia is not typically reported.
Choice D rationale:
Hypotension, or low blood pressure, is not typically associated with the use of quinolones. These antibiotics can have various side effects, but a significant drop in blood pressure is not commonly reported.
Correct Answer is B
Explanation
Choice A rationale:
Shaking the insulin vial vigorously is not recommended. It can lead to the formation of bubbles, which can affect the accuracy of the dose. Instead, insulin vials should be gently rolled between the hands to mix.
Choice B rationale:
Injecting insulin into the abdominal area is indeed a recommended practice. The abdomen is a preferred site for insulin injection because it has a faster absorption rate compared to other areas. This can help to more effectively regulate blood glucose levels.
Choice C rationale:
Exercise typically lowers blood glucose levels, so insulin doses may need to be reduced to prevent hypoglycemia. Clients should monitor their blood glucose closely and adjust insulin as directed by their healthcare provider.
Choice D rationale:
Freezing unopened insulin vials is not advised. Freezing can disrupt the insulin structure, rendering it ineffective. Insulin should be stored in a refrigerator at a temperature between 2°C and 8°C (36°F and 46°F). Once opened, it can be kept at room temperature for up to 28 days.
