Question 1 of 5
A common complication of using thrombolytic drugs S
Correct Answer: D
Rationale: The correct answer is D: Bleeding. Thrombolytic drugs work by dissolving blood clots, which can lead to an increased risk of bleeding as they break down the clots. This is a well-known and serious complication associated with thrombolytic therapy. Nausea, hypertension, and fever are not common complications of thrombolytic drugs. Bleeding is a critical consideration due to the potential for serious consequences such as hemorrhage.
Therefore, it is crucial to monitor patients closely for signs of bleeding when using thrombolytic drugs.
Question 2 of 5
Calculate the following dosage using ratio and proportions method (Round answers to the nearest tenth). Order: Digoxin 0.375mg p. o. daily. Available: Digoxin (scored tablets) labeled 0.25mg
Correct Answer: B
Rationale:
To calculate the correct dosage of Digoxin, we set up a proportion: 0.375mg is to 1 tablet as X mg is to 0.25mg. Cross-multiply to get 0.375 = 0.25X, then divide 0.375 by 0.25 to find X = 1.5 tablets.
Choice B is correct as it represents the calculated dosage.
Choices A, C, and D are incorrect because they do not match the calculated result.
Choice A would result in an overdose, choice C is too small of a dose, and choice D is too high of a dose.
Question 3 of 5
A nurse is assisting in preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram. Which of the following transcription examples should the nurse use?
Correct Answer: A
Rationale: The correct answer is A: 0.2 mg. When transcribing a dosage of two tenths of a milligram, it should be written as 0.2 mg to clearly indicate the decimal point.
Choice B (.2 mg) lacks the leading zero before the decimal point, which can be misread as 2 mg.
Choice C (2.0 mg) incorrectly indicates a dosage of 2 mg, not 0.2 mg.
Choice D (0.20 mg) is unnecessarily precise for two tenths of a milligram.
Choices E, F, and G are not provided, making them incorrect by default.
Therefore, option A is the most accurate and clear representation of the dosage of two tenths of a milligram.
Question 4 of 5
When administering an antianginal drug such as nitroglycerin (NTG) the nurse identifies which as the most common response.
Correct Answer: C
Rationale: The correct answer is C: Hypotension. Nitroglycerin causes vasodilation, leading to decreased systemic vascular resistance and blood pressure. This is the most common response because it is a desired effect in treating angina by improving myocardial oxygen supply. Bradycardia (
A) and tachycardia (
B) are less common with nitroglycerin. Dry mouth (
D) is not a typical side effect of nitroglycerin.
Question 5 of 5
Before drug reconstitution, the nurse would check the drug circular and/or drug label for instructions. After a drug has been reconstituted and additional doses are available, which information would the nurse write on the drug label? (Select all that apply.)
Correct Answer: B,C,D
Rationale: The correct answers are B, C, and D. B: The diluent should be recorded on the label for future reference. C: The date to discard is crucial to ensure the drug's potency and safety. D: Initials are important for tracking who reconstituted the drug. A is incorrect as the provider's order is typically documented in the patient's chart, not on the drug label.
Choices E, F, and G are left blank as they are not relevant to the information needed on a drug label post-reconstitution.
