Question 1 of 5
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 ml via intermittent IV bolus over 30 min. The drop factor of the manual IV tubing is 15 gtt/ml. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 50
Rationale: The correct answer is 50 gtt/min.
To calculate the infusion rate in drops per minute (gtt/min), we use the formula: (Volume to be infused in ml × drop factor) ÷ time in minutes. In this case, (100 ml × 15 gtt/ml) ÷ 30 min = 1500 gtt ÷ 30 min = 50 gtt/min. This ensures the correct administration rate for cefazolin. Other choices are incorrect because they do not follow the correct calculation method or do not result in the appropriate infusion rate.
Question 2 of 5
A nurse is assessing the vital signs of a client who is taking amiodarone. The nurse should anticipate which of the following findings as an adverse effect of the medication?
Correct Answer: B
Rationale: The correct answer is B: Bradycardia. Amiodarone is an antiarrhythmic medication that can cause bradycardia as an adverse effect due to its action on the heart's electrical conduction system. This can lead to a slow heart rate, which the nurse should monitor for. The other choices are incorrect because hypertension (
A) is not a common adverse effect of amiodarone, fever (
C) is not typically associated with this medication, and bradypnea (
D) refers to slow breathing rate, which is not a typical adverse effect of amiodarone.
Question 3 of 5
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 ml via intermittent IV bolus over 30 min. The drop factor of the manual IV tubing is 15 gtt/ml. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 50
Rationale: The correct answer is 50 gtt/min.
To calculate the infusion rate in drops per minute (gtt/min), we use the formula: (Volume to be infused in ml × drop factor) ÷ time in minutes. In this case, (100 ml × 15 gtt/ml) ÷ 30 min = 1500 gtt ÷ 30 min = 50 gtt/min. This ensures the correct administration rate for cefazolin. Other choices are incorrect because they do not follow the correct calculation method or do not result in the appropriate infusion rate.
Question 4 of 5
A nurse is preparing to mix short-acting insulin with NPH insulin from two vials. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: The correct answer is D: Inject air into the vial to withdraw the short-acting insulin. This step is necessary to prevent creating a vacuum in the vial, which can make it difficult to withdraw the insulin. By injecting air into the vial before withdrawing the short-acting insulin, the nurse ensures smooth and accurate extraction of the medication. Using two separate syringes (choice
A) is unnecessary as long as the nurse follows proper technique. Ensuring NPH insulin is drawn first (choice
B) is not necessary and may lead to errors in dosage. Administering the insulin within 20 minutes (choice
C) is not relevant to the preparation process.
Question 5 of 5
A nurse is assessing a client who has a prescription for cefaclor. Which of the following findings should the nurse recognize as an indication of an allergic reaction?
Correct Answer: C
Rationale: The correct answer is C: Pruritus. Pruritus, or itching, is a common symptom of an allergic reaction to medications like cefaclor. It is caused by the release of histamine in response to the allergen. Hematuria (
A) is blood in the urine, not typically associated with allergic reactions. Tremor (
B) and slurred speech (
D) are neurological symptoms, not typical of allergic reactions.
