Question 1 of 5
A nurse is planning to administer medications to a client who weighs 198 lb. The prescription reads, 'filgrastim 5 mcg/kg, subcutaneous, daily.' Available is filgrastim 300 mcg/mL. How many mL should the nurse plan to give with each dose?
Correct Answer: A
Rationale:
To calculate the dose of filgrastim, we first need to convert the client's weight from pounds to kilograms. 198 lb is approximately 89.9 kg.
Then, we multiply the weight by the prescribed dose (5 mcg/kg) to get the total dose required, which is 449.5 mcg. Next, we divide the total dose by the concentration of the available filgrastim (300 mcg/mL) to find the volume needed, which is 1.5 mL.
Therefore, the correct answer is A.
Choices B, C, and D are incorrect as they do not match the calculated dose based on the client's weight and the prescribed dosage of filgrastim.

Question 3 of 5
A nurse is assessing a client who has muscarinic agonist poisoning. Following administration of atropine, which of the following findings should indicate to the nurse that the treatment has been effective?
Correct Answer: B
Rationale: The correct answer is B: Heart rate 90/min. Atropine is given to treat muscarinic agonist poisoning by blocking the effects of excessive acetylcholine, which slows down the heart rate.
Therefore, if the heart rate increases to a more normal range like 90/min after atropine administration, it indicates that the treatment has been effective in reversing the toxic effects. The other choices are incorrect because hyperactive bowel sounds (
A) and increased salivation (
D) are symptoms of muscarinic agonist poisoning that atropine would aim to reduce. Similarly, low blood pressure (
C) is a common symptom of muscarinic agonist poisoning and atropine would aim to increase blood pressure by reversing the effects of excessive acetylcholine.
Question 4 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 5 of 5
A nurse is instructing a client who has a new prescription for a daily dose of lovastatin extended release. Which of the following information should the nurse include in the teaching?
Correct Answer: D
Rationale: The correct answer is D: "You will need liver function tests before beginning therapy." This is important because lovastatin, as a statin medication, can potentially cause liver damage. Liver function tests are necessary to monitor any adverse effects. Option A is incorrect because there is no need to avoid dairy products with lovastatin. Option B is incorrect as extended-release medications should not be crushed. Option C is incorrect as the timing of the medication is not specified.
