Question 1 of 5
The nurse is caring for a client with an oral temperature of 100.6 F. What temperature in Celsius should the nurse document in the medical record? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 38.1
Rationale:
To find the answer, we can use the following formula: (Celsius) = (Fahrenheit - 32) x (5 / 9). Substituting the given value, we get: (Celsius) = (100.6 - 32) x (5 / 9). Simplifying, we get: (Celsius) = 68.6 x (5 / 9). (Celsius) = 38.111. (rounded Celsius) = 38.1.
Therefore, the nurse should document the oral temperature as 38.1 C in the medical record.
Question 2 of 5
A client receives a prescription for loratadine suspension 10 mg by mouth once a day. The bottle is labeled 'Loratadine for Oral Suspension, USP 5 mg per 5 mL.' How many teaspoons should the nurse instruct the client to take? (Enter numerical value only.)
Correct Answer: 2
Rationale:
To find the answer, we can use the following steps: Calculate the volume of loratadine suspension in mL by dividing the dose in mg by the concentration in mg/mL. Convert the volume in mL to teaspoons by multiplying by 0.2. Round the result to the nearest whole number. Using these steps, we get: (volume in mL) = (10) / (5 / 5) = 10 mL. (volume in teaspoons) = (10) x (0.2) = 2 teaspoons. (rounded volume in teaspoons) = 2 teaspoons.
Therefore, the nurse should instruct the client to take 2 teaspoons of loratadine suspension.
Question 3 of 5
A client returns from the PACU with a bag of IV fluids that has 630 mL remaining in the 1,000 mL bag. The prescription reads, 'Continue the present IV over the next 7 hours.' The IV administration set delivers 10 gtt/mL. The nurse should regulate the infusion to deliver how many drops/minute to accomplish the new prescription? (Enter numeric value only.)
Correct Answer: 15
Rationale:
To find the answer, we can use the following steps: Calculate the infusion rate in mL/hour by dividing the volume of IV fluids by the time of infusion. Calculate the infusion rate in mL/minute by dividing the infusion rate in mL/hour by 60. Multiply the infusion rate in mL/minute by the drop factor in gtt/mL to get the infusion rate in gtt/minute. Round the result to the nearest whole number. Using these steps, we get: (infusion rate in mL/hour) = (630) / (7) = 90 mL/hour. (infusion rate in mL/minute) = (90) / (60) = 1.5 mL/minute. (infusion rate in gtt/minute) = (1.5) x (10) = 15 gtt/minute. (rounded infusion rate in gtt/minute) = 15.
Therefore, the nurse should regulate the infusion to deliver 15 gtt/minute of IV fluids to the client.
Question 4 of 5
The nurse plans to provide the next shift with the IV fluid balance for a client who had a 440 mL secondary infusion that was started 2 hours ago at a rate of 85 mL/hour via an infusion pump. What is the remaining volume to be infused? (Enter numeric value only.)
Correct Answer: 270
Rationale:
To find the answer, we can use the following formula: (remaining volume) = (initial volume) - (infused volume). Substituting the given values, we get: (remaining volume) = (440) - ((85 x 2)). Simplifying, we get: (remaining volume) = (440) - (170). (remaining volume) = 270.
Therefore, the remaining volume to be infused is 270 mL.
Question 5 of 5
A patient with a renal calculi receives a prescription for an intravenous infusion of 0.9% Sodium chloride Injection, USP 1,000 mL to be infused over 2.5 hours. The nurse should program the infusion pump to deliver how many mL/hour?(Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 400
Rationale:
To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (1000 / 150) x 60. Simplifying, we get: (mL/hour) = 6.667 x 60. (mL/Hour) = 400.
Therefore, the nurse should program the infusion pump to deliver 400 mL/hour of 0.9% Sodium chloride Injection, USP to the patient.
