ATI Nurs 180 Pharmacology Exam Questions
Extract:
Question 1 of 5
The nurse is caring for a client who suffers from frequent blood clots and currently taking argatroban (Hospira). Which of the following conditions in the client's medical history would require them to take argatroban (Hospira)?
Correct Answer: A
Rationale: The correct answer is A: Heparin induced thrombocytopenia (HIT). Argatroban is a direct thrombin inhibitor used specifically for the treatment of HIT. HIT is a serious complication of heparin therapy characterized by a drop in platelet count and increased risk of blood clot formation. Argatroban helps prevent further clot formation by inhibiting thrombin.
Choice B (Myocardial infarction) is incorrect because argatroban is not typically used for the treatment of myocardial infarction.
Choice C (Gastrointestinal bleeding) is incorrect as argatroban does not specifically treat this condition.
Choice D (Hepatotoxicity) is incorrect as there is no direct indication for the use of argatroban in hepatotoxicity.
Question 2 of 5
A client with hypertension and benign prostate hyperplasia is prescribed doxazosin (Cardura). Which of the following statements below would the nurse emphasize regarding doxazosin (Cardura)?
Correct Answer: B
Rationale: The correct answer is B: Be sure to lie down after taking the first dose, because first-dose hypotension may make you dizzy. Doxazosin is an alpha-1 blocker that can cause sudden drop in blood pressure, especially with the first dose. By lying down after taking the first dose, the client can minimize the risk of dizziness and falls.
A: Weighing daily and reporting weight loss is not directly related to doxazosin.
C: Impaired taste is not a common side effect of doxazosin.
D: There is no need to increase potassium intake specifically with doxazosin unless advised by a healthcare provider for other reasons.
Question 3 of 5
A client who suffers from hypertension and headaches is prescribed esmolol (Brevibloc). The nurse would educate the client on which side effects associated with this medication? (Select All that Apply.)
Correct Answer: A,C,D
Rationale: The correct answers are A, C, and D. A: Esmolol, a beta-blocker, can cause rebound hypotension when stopped abruptly. C: It can lead to bradycardia due to its effect on reducing heart rate. D: Esmolol can mask hypoglycemic symptoms such as tachycardia, which can be dangerous. B: Vomiting is not a common side effect of esmolol.
Therefore, it is not correct.
Question 4 of 5
A client who has just experienced a pulmonary embolism is administered alteplase (Activase). Which of the following side effects associated with this medication would the nurse assess for?
Correct Answer: B
Rationale: The correct answer is B: Internal bleeding. Alteplase is a thrombolytic medication that works by breaking down blood clots. One of the major side effects of thrombolytic therapy is the risk of internal bleeding due to the medication's ability to break down clots, which can lead to bleeding in various parts of the body. The nurse should closely monitor the client for signs of bleeding, such as bruising, bleeding gums, blood in urine or stool, and decreased blood pressure.
A: Hypokalemia is not a common side effect of alteplase.
C: Pancytopenia is a decrease in all three blood cell types (red blood cells, white blood cells, and platelets) and is not typically associated with alteplase.
D: Hypertension is not a common side effect of alteplase.
Therefore, B is the correct answer as internal bleeding is a significant side effect to monitor for in a client receiving altepl
Question 5 of 5
The nurse is preparing to administer digoxin (Lanoxin) to a client experiencing atrial fibrillation. Which of the following electrolyte imbalances would the nurse assess to reduce the incidence of toxicity with digoxin (Lanoxin)?
Correct Answer: B
Rationale: The correct answer is B: Hypokalemia. Digoxin toxicity is more likely to occur in patients with low potassium levels because potassium competes with digoxin for binding sites on the Na+/K+ ATPase pump. Low potassium levels can lead to increased digoxin binding, resulting in toxicity. Assessing and correcting hypokalemia before administering digoxin can help reduce the risk of toxicity.
Incorrect choices:
A: Hypocalcemia does not directly affect digoxin toxicity.
C: Hyperkalemia actually reduces the risk of digoxin toxicity.
D: Hypernatremia is not directly related to digoxin toxicity.
