ATI Capstone Pharmacology Assessment 1
1. A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacologic action of this medication?
- A. To stimulate the pancreas to secrete insulin
- B. To slow the absorption of glucose in the intestine
- C. To increase reabsorption of water in the renal tubules
- D. To increase blood pressure
Correct answer: C
Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin, also known as antidiuretic hormone (ADH), works by increasing the reabsorption of water in the renal tubules, which helps to concentrate urine and reduce excessive urination in diabetes insipidus. Choice A is incorrect as vasopressin does not stimulate the pancreas to secrete insulin. Choice B is incorrect as vasopressin does not affect the absorption of glucose in the intestine. Choice D is incorrect as vasopressin's primary action is not to increase blood pressure, although it can have some vasoconstrictive effects.
2. A healthcare provider is preparing to administer heparin sodium to a client with deep vein thrombosis (DVT). Which of the following laboratory values should the provider monitor during therapy?
- A. INR
- B. Serum creatinine
- C. aPTT
- D. Bilirubin
Correct answer: C
Rationale: The correct answer is C: aPTT. The healthcare provider should monitor the activated partial thromboplastin time (aPTT) value during heparin therapy to assess the client's coagulation status. Heparin affects the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps ensure that the client is within the therapeutic range to prevent bleeding or clotting issues. INR (Choice A) is used to monitor warfarin therapy, not heparin. Serum creatinine (Choice B) is not directly related to monitoring heparin therapy. Bilirubin (Choice D) is related to liver function, not heparin therapy.
3. A client prescribed lisinopril for hypertension may experience which of the following side effects that the nurse should monitor for?
- A. Cough
- B. Weight gain
- C. Dry mouth
- D. Hyperglycemia
Correct answer: A
Rationale: A persistent dry cough is a common side effect of lisinopril. Lisinopril is an ACE inhibitor that can cause a cough due to the accumulation of bradykinin. Weight gain, dry mouth, and hyperglycemia are not typically associated with lisinopril use, making them incorrect choices in this scenario.
4. When administering amlodipine to a client with hypertension, what adverse effect should the nurse monitor for?
- A. Constipation
- B. Facial flushing
- C. Hypotension
- D. Jaundice
Correct answer: C
Rationale: The correct answer is C, Hypotension. Amlodipine is a calcium channel blocker commonly used to treat hypertension. One of the main adverse effects of amlodipine is hypotension, leading to low blood pressure. The nurse should monitor the client for signs of hypotension such as dizziness, lightheadedness, or fainting. Choices A, B, and D are incorrect because constipation, facial flushing, and jaundice are not typically associated with amlodipine administration.
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?
- A. White blood cell count
- B. Hematocrit
- C. Platelet count
- D. Red blood cell count
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.
