Question 1 of 5
Low molecular weight heparin (LMWH) is used for what type of patient?
Correct Answer: D
Rationale:
Correct
Answer: D - Patients with deep vein thrombosis (DVT)
Rationale: LMWH is commonly used for the treatment and prevention of conditions such as DVT due to its ability to inhibit blood clot formation. Patients with DVT benefit from LMWH as it helps prevent the clot from growing larger or breaking off and traveling to the lungs, causing a pulmonary embolism.
Summary of Incorrect
Choices:
A: Patients with hypertension - LMWH is not indicated for the treatment of hypertension.
B: Patients with asthma - LMWH is not indicated for the treatment of asthma.
C: Patients with diabetes - LMWH is not specifically indicated for the treatment of diabetes.
Question 2 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 3 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 4 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 5 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.
