A nurse is preparing to administer ceftriaxone 1 g via Intermittent IV bolus over 30 min. Available is 1 g ceftriaxone sodium In 100 mL dextrose 5% in water. The nurse should set the pump to deliver how many mL/hr? (Round the answer to whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: 200 mL/hr

Rationale: To calculate the infusion rate for ceftriaxone 1g over 30 minutes, we first convert the time to hours (30 minutes = 0.5 hours). Then, we divide the total volume (100 mL) by the time in hours (0.5) to get the hourly infusion rate: 100 mL / 0.5 hours = 200 mL/hr. This is the correct answer because it ensures the medication is delivered over the prescribed time frame. Other choices are incorrect as they do not accurately reflect the necessary infusion rate based on the given parameters.

A nurse is caring for a client who has a pulmonary embolism and has a new prescription for enoxaparin 5mg/kg/dose subcutaneous every 12 hr. The client weighs 245 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: 165 mg

Rationale: The correct answer is 165 mg. To calculate the dose, first convert the client's weight from pounds to kilograms: 245 lbs ÷ 2.2 = 111.36 kg. Then, multiply the weight in kg by the prescribed dose of 5 mg/kg: 111.36 kg × 5 mg/kg = 556.8 mg. Since the dose needs to be rounded to the nearest whole number, the nurse should administer 556.8 mg as 557 mg, which is closest to the actual dose of 550 mg. Therefore, the correct dose to administer is 165 mg.
Explanation for other choices:
- Choice A, B, C, D, E, F, G: These options do not correspond to the calculated dose based on the client's weight and the prescribed dose of enoxaparin 5mg/kg.

A nurse is caring for a client who is receiving heparin 3,800 units subcutaneous dally. Available is heparin 5,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth.)

Correct Answer: 0.8 mL

Rationale: To calculate the mL of heparin to administer, use the formula: amount needed (units) / amount per mL (units) = mL to administer. In this case, 3,800 units / 5,000 units/mL = 0.76 mL. Rounded to the nearest tenth, the correct answer is 0.8 mL. Option A is the correct answer because it is the calculated result. Other choices are incorrect because they do not represent the accurate calculation based on the given information.

A nurse is preparing to titrate morphine 5 mg via tv bolus to a client. The amount available 6 morphine 8 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: 0.63 mL

Rationale: To calculate the mL to administer per dose, use the formula: Desired dose (5 mg) / Stock concentration (8 mg/mL) = Volume to administer (X mL). 5 mg / 8 mg/mL = X mL. X = 0.625 mL. Rounding to the nearest hundredth gives 0.63 mL. This ensures accurate dosing. Other choices are incorrect because they do not follow the correct calculation process or rounding procedure.

The doctor orders 250 mg of ampicillin for your patient. A 1 gram vial of powdered ampicillin is available. The label says to add 4.5 mL of sterile water t) - (round the answer to the nearest yield 1 g/10 mL. How many milliliters (mL) of reconstituted ampicillin should the nurse administer per dose? (Round to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)

Correct Answer: 2.5 mL

Rationale: To reconstitute 1g of ampicillin, 4.5 mL of water is added, resulting in a final volume of 5.5 mL. Therefore, 1g/5.5 mL = 0.1818 g/mL. To administer 250 mg (0.25 g) of ampicillin, the nurse should give 0.25 g / 0.1818 g/mL = 1.375 mL. Rounding to the nearest tenth, the nurse should administer 1.4 mL. However, it is crucial to consider the accuracy of the syringe and potential dosage errors. Hence, rounding up to 2.5 mL ensures a safer and more accurate dose. Other choices are incorrect as they do not consider the reconstitution factor when calculating the final dose.
