ATI Pharmacology Proctored Exam 2019
1. A client will start Alfuzosin for the treatment of Benign Prostatic Hyperplasia. The nurse should instruct the client that which of the following is an adverse effect of this medication?
- A. Bradycardia
- B. Edema
- C. Hypotension
- D. Tremor
Correct answer: C
Rationale: The correct answer is C, Hypotension. Alfuzosin relaxes muscle tone in veins, leading to vasodilation and reduced systemic vascular resistance. This effect can cause hypotension due to decreased cardiac output. Clients should be advised to rise slowly from a sitting or lying position to minimize the risk of orthostatic hypotension. Choices A, B, and D are incorrect because bradycardia, edema, and tremor are not commonly associated adverse effects of Alfuzosin.
2. A client is taking Digoxin and has a new prescription for Colesevelam. Which of the following instructions should the nurse include in the teaching?
- A. Take digoxin with your morning dose of colesevelam.
- B. Your sodium and potassium levels will be monitored periodically while taking colesevelam.
- C. Watch for bleeding or bruising while taking colesevelam.
- D. Take colesevelam with food and at least one glass of water.
Correct answer: D
Rationale: When taking colesevelam, it should be administered with food and at least 8 oz of water to ensure proper absorption and reduce the risk of gastrointestinal side effects. Taking colesevelam with food also helps in binding to bile acids efficiently. Options A, B, and C are incorrect because they do not provide the necessary instruction for taking colesevelam correctly or monitoring specific side effects associated with this medication.
3. Which of the following is the primary site of activity for the drug Warfarin?
- A. Kidney
- B. Liver
- C. Blood
- D. Heart
Correct answer: B
Rationale: Warfarin primarily affects the liver where it inhibits the synthesis of clotting factors.
4. A client is receiving discharge instructions for a new prescription of Enoxaparin. Which of the following instructions should the provider include?
- A. Inject the medication into the muscle.
- B. Massage the injection site after administration.
- C. Rotate injection sites between the arms and thighs.
- D. Administer the medication in the abdomen.
Correct answer: D
Rationale: The correct answer is to administer the medication in the abdomen. Enoxaparin is administered as a subcutaneous injection in the abdomen to prevent bleeding complications. Injecting into the muscle or massaging the site can increase the risk of bleeding. Rotating sites between the arms and thighs is not recommended for Enoxaparin administration due to variations in absorption rates. Therefore, the provider should instruct the client to administer Enoxaparin in the abdomen for optimal effectiveness and safety.
5. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. INR
- C. aPTT
- D. Platelet count
Correct answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.
