Question 1 of 5
A nurse is administering medications to a client who weighs 132 lb. The prescription reads chloramphenicol, 50mg/kg/day in 4 divided doses. Available is chloramphenicol 100 mg/mL. How many mL should the nurse give with each dose?
Correct Answer: A
Rationale: The correct answer is A (7.5 mL).
To calculate the dose, first determine the total daily dose: 50mg/kg/day x 132 lb = 6600 mg. Next, divide the total daily dose by the number of doses per day (4 doses) to get the dose per administration: 6600 mg / 4 = 1650 mg. Finally, calculate the volume needed for each dose by dividing the dose per administration by the concentration of the medication (100 mg/mL): 1650 mg / 100 mg/mL = 16.5 mL. Since the question specifies 4 divided doses, divide the total daily volume (16.5 mL) by 2 to get the volume for each divided dose: 16.5 mL / 2 = 8.25 mL, which rounds to 7.5 mL.
Choice B is incorrect because it does not account for the divided doses accurately.
Choices C and D are incorrect as they do not align
Question 2 of 5
A nurse is assessing a client who received midazolam IV for moderate (conscious) sedation. Which of the following assessments is the nurse's priority?
Correct Answer: C
Rationale: The correct answer is C: Level of consciousness. When a client receives midazolam for conscious sedation, the priority assessment is the level of consciousness to ensure the client is responsive and maintains airway patency. This assessment allows the nurse to monitor for any signs of over-sedation or respiratory depression, which are potential side effects of midazolam. Monitoring the client's temperature, heart rate, and oxygen saturation are important, but they are secondary to assessing the level of consciousness in this scenario. Checking the temperature may be important for general assessment, heart rate for potential adverse effects, and oxygen saturation for respiratory status, but the primary concern is ensuring the client remains conscious and responsive during the sedation procedure.
Question 3 of 5
A nurse is preparing to administer propranolol to a client. Which of the following should the nurse assess prior to administering this medication?
Correct Answer: C
Rationale: The correct answer is C: Heart rate. Before administering propranolol, a beta-blocker, the nurse should assess the client's heart rate because this medication works by slowing down the heart rate and reducing blood pressure. Monitoring the heart rate helps ensure the medication is given safely and effectively. Assessing pain level (
A) is important but not directly related to propranolol administration. Temperature (
B) is not typically a crucial assessment before giving propranolol. Respiratory rate (
D) is also important but not the priority when administering this medication.
Question 4 of 5
A nurse is assessing a client who has a transdermal fentanyl patch in place. Which of the following findings should the nurse document as an adverse effect of this medication?
Correct Answer: C
Rationale: The correct answer is C: Hypotension. Fentanyl, a potent opioid, can cause hypotension as an adverse effect due to its central nervous system depressant effects, leading to a decrease in blood pressure. Tachycardia (
A) is less common with fentanyl, insomnia (
B) is not a typical side effect, and diarrhea (
D) is also less likely. It is crucial for the nurse to monitor for signs of hypotension when a client is on a fentanyl patch to prevent complications.
Question 5 of 5
A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Monitor the client's weight daily. Monitoring the client's weight daily is essential when administering TPN to assess fluid balance and nutritional status. Weight changes can indicate fluid retention or loss, helping to adjust the TPN solution accordingly. Hanging the TPN to gravity (
A) is incorrect as TPN should be administered using an infusion pump to control the rate accurately. Titrating TPN to blood pressure (
C) is incorrect as TPN is not adjusted based on blood pressure but rather individual nutritional needs. Obtaining the client's blood glucose level weekly (
D) is important but not as crucial as monitoring weight daily to ensure adequate TPN therapy.
