ATI Capstone Pharmacology Assessment 1 Questions
Question 1 of 5
A client with an artificial heart valve is prescribed warfarin therapy. Which of the following laboratory values should the nurse monitor to assess the therapeutic effect of warfarin?
Correct Answer: B
Rationale: The correct answer is B: Prothrombin time (PT). Warfarin is an anticoagulant medication that works by inhibiting the clotting factors dependent on vitamin K, such as factors II, VII, IX, and X. The prothrombin time (PT) measures the extrinsic pathway and is used to monitor the therapeutic effects of warfarin therapy. Monitoring PT helps assess the time it takes for the blood to clot, ensuring that the anticoagulant effect is within the desired range. Choices A, C, and D are incorrect because hemoglobin (Hgb) measures the amount of hemoglobin in the blood, bleeding time assesses the time it takes for bleeding to stop, and activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin therapy.
Question 2 of 5
A nurse is caring for a client taking ciprofloxacin for an infection. Which of the following adverse effects should the nurse include in the client education?
Correct Answer: B
Rationale: The correct answer is B: Tendon rupture. Ciprofloxacin belongs to the fluoroquinolone class of antibiotics, which is associated with the adverse effect of tendon rupture. Tendon rupture is a severe but rare side effect that can occur with the use of ciprofloxacin. Educating the client about this potential adverse effect is crucial to promote awareness and early recognition of symptoms, such as tendon pain, swelling, or inflammation. Choices A, C, and D are not typically associated with ciprofloxacin use and are less relevant for client education in this scenario.
Question 3 of 5
A nurse is preparing to administer potassium chloride IV to a client. Which of the following actions should the nurse take to prevent complications?
Correct Answer: B
Rationale: The correct action to prevent complications when administering potassium chloride IV is to infuse the medication slowly using an IV pump. Rapid administration of potassium chloride can lead to complications such as hyperkalemia and cardiac arrest. Options A, C, and D are incorrect as they do not promote the safe administration of potassium chloride. Administering the medication by IV bolus over 2 minutes is too rapid and can cause adverse effects. Adding the medication to an IV solution of D5W or diluting it in sterile water may not control the rate of administration, increasing the risk of complications.
Question 4 of 5
A nurse is reviewing a client's medication regimen. Which of the following medications places the client at increased risk for digoxin toxicity?
Correct Answer: D
Rationale: The correct answer is D, Loop diuretics. Loop diuretics can lead to hypokalemia, which increases the risk for digoxin toxicity. Loop diuretics cause potassium loss, and hypokalemia can potentiate the toxic effects of digoxin. Choices A, B, and C are incorrect because calcium channel blockers, potassium-sparing diuretics, and beta blockers do not directly increase the risk of digoxin toxicity.
Question 5 of 5
A nurse is caring for a client prescribed enoxaparin for deep vein thrombosis prophylaxis. Which of the following client assessments requires immediate intervention?
Correct Answer: A
Rationale: A platelet count of 95,000/mm³ requires immediate intervention as it is low and increases the risk of bleeding, which is a potential complication of enoxaparin therapy. Low platelet counts can predispose the patient to hemorrhage, and administering anticoagulants like enoxaparin in such cases can further increase the bleeding risk. Monitoring platelet counts is crucial during anticoagulant therapy to prevent serious bleeding complications. The other options do not pose immediate risks related to enoxaparin therapy. A slightly elevated blood pressure, a heart rate of 95 beats per minute, and pain at the injection site are common findings that may not warrant immediate intervention in this context.
