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 55-year-old client has levothyroxine ordered. Which of the below past medical history concerns may contraindicate with her medication management of hypothyroidism?
Correct Answer: B
Rationale: The correct answer is B: Osteoporosis. Osteoporosis is a concern with levothyroxine as it can increase the risk for fractures, particularly in older adults. Levothyroxine treatment can exacerbate bone loss in individuals with osteoporosis.
Choices A, C, and D are not directly contraindicated with levothyroxine therapy for hypothyroidism.
Question 3 of 5
A client receiving epoetin alfa therapy for anemia is being monitored for therapeutic effects. Which of the following laboratory values indicates the medication is effective?
Correct Answer: B
Rationale: The correct answer is B: Hematocrit. An increase in hematocrit levels indicates the effectiveness of epoetin alfa in treating anemia. Hematocrit reflects the percentage of red blood cells in the blood, so an increase in hematocrit signifies an improvement in the patient's red blood cell count and oxygen-carrying capacity.
Choices A, C, and D are incorrect because white blood cell count, platelet count, and red blood cell count do not directly reflect the therapeutic effects of epoetin alfa in treating anemia.
Question 4 of 5
A healthcare professional is caring for a client receiving gentamicin therapy. Which of the following client assessments is a priority for the healthcare professional to monitor for an adverse effect of this medication?
Correct Answer: D
Rationale: The correct answer is D: Hearing acuity. Gentamicin is known to be ototoxic, which means it can cause damage to the auditory system leading to hearing loss. Monitoring hearing acuity is crucial to detect early signs of hearing impairment. Monitoring urinary output (choice
A) is important for assessing kidney function but is not directly related to gentamicin's adverse effects. Monitoring serum glucose (choice
B) and respiratory rate (choice
C) are not specifically associated with gentamicin therapy.
Question 5 of 5
A nurse is caring for a client prescribed digoxin. Which of the following should alert the nurse to possible digitalis toxicity?
Correct Answer: A
Rationale: The correct answer is A: Anorexia and weakness. These symptoms are early indicators of potential digitalis toxicity. Anorexia refers to a loss of appetite, which can be a sign of toxicity, and weakness can indicate an issue with digoxin.
Choices B, C, and D are incorrect. Hyperactivity and hunger, tachycardia and increased urination, as well as polyphagia and polydipsia are not typically associated with digitalis toxicity.
