Question 1 of 5
When converting from IV heparin to oral warfarin (Coumadin) therapy, the prescriber monitors which of the following to determine the next appropriate dose of warfarin?
Correct Answer: D
Rationale: The correct answer is D: PT/INR. When converting from IV heparin to oral warfarin therapy, the prescriber monitors PT/INR to determine the next appropriate dose of warfarin. PT/INR reflects the anticoagulant effect of warfarin, guiding dose adjustments. Platelet levels (A) assess clotting function, not warfarin effectiveness. aPTT (B) monitors heparin therapy, not warfarin. Red blood cell count (C) is unrelated to monitoring warfarin therapy.
Question 2 of 5
A patient has received an IV dose of adenosine, and almost immediately the heart monitor shows
Correct Answer: B
Rationale: The correct answer is B: Check the patient's pulse. After administering adenosine, which is a medication used to treat certain heart rhythm problems, it can cause a temporary pause in the heart rhythm. Checking the patient's pulse is crucial to assess the effectiveness of the medication and monitor for any potential adverse effects. This step allows the nurse to determine the patient's cardiac status and response to the medication accurately. Option A is vague and does not provide specific guidance. Option D is premature as administering CPR is not warranted unless the patient is in cardiac arrest. Option C is incomplete and does not offer any actionable steps to assess the patient's condition.
Question 3 of 5
When starting a patient on antidysrhythmic therapy, the nurse will remember that which problem is a potential adverse effect of any antidysrhythmic drug?
Correct Answer: D
Rationale: The correct answer is D: Dysrhythmias. Antidysrhythmic drugs can paradoxically cause new or worsened dysrhythmias due to their mechanism of action on the heart's electrical conduction system. This can lead to potentially life-threatening arrhythmias. Deficiency of fat-soluble vitamins (choice A) is not a common adverse effect of antidysrhythmic drugs. Hyperkalemia (choice B) and heart failure (choice C) can be potential complications of some medications but are not the primary adverse effect of antidysrhythmics. Dysrhythmias (choice D) are the main concern when initiating antidysrhythmic therapy due to the drug's effects on cardiac conduction.
Question 4 of 5
A nurse is about to administer Propanolol to a patient. The nurse takes the patient's apical pulse and documents it as 58 bmp. How should the nurse continue?
Correct Answer: D
Rationale: The correct answer is D: Withhold administration of the medication and notify the physician. An apical pulse of 58 bmp indicates bradycardia, which is a contraindication for Propranolol, a beta-blocker that can further reduce heart rate. By withholding the medication and informing the physician, the nurse ensures patient safety and avoids potential harm. Cutting the tablet in half (choice B) or giving the XR form (choice C) would still expose the patient to the medication, risking adverse effects. Administering the medication as normal (choice A) would be unsafe due to the already low heart rate.
Question 5 of 5
Prior to administration of levothyroxine, which of the following should the nurse complete? (Select all that apply)
Correct Answer: C
Rationale: The correct answer is C: Assess weight. Before administering levothyroxine, the nurse should assess the patient's weight because levothyroxine dosage is often based on weight. This ensures accurate dosing and prevents under or overdosing. Assessing degree of numbness (A) and monitoring for intensified pain (B) are not directly related to levothyroxine administration. Assessing apical pulse (D) is important for monitoring thyroid function, but it is not a prerequisite before administering levothyroxine.
