HESI Practice Test Pharmacology
1. A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?
- A. Platelet count
- B. Prothrombin time
- C. Partial thromboplastin time
- D. Serum levels of protamine sulfate
Correct answer: C
Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.
2. A client is prescribed clonidine 0.1 mg/24 hours via a transdermal patch. Which client outcome would indicate that the medication is effective?
- A. No complaints of recent episodes of angina
- B. Change in peripheral edema from +3 to +1
- C. No complaints of new onset of nausea or vomiting
- D. Blood pressure changes from 180/120 to 140/70 mm Hg
Correct answer: D
Rationale: Clonidine is an antihypertensive agent that works centrally to reduce blood pressure. A significant decrease in blood pressure, such as changing from 180/120 to 140/70 mm Hg, indicates that the medication is effectively managing hypertension. Monitoring blood pressure levels is crucial in assessing the response to clonidine therapy. Choices A, B, and C are incorrect as they do not directly relate to the therapeutic effect of clonidine in managing hypertension, which is the primary goal of the medication in this scenario.
3. A client is prescribed nitroglycerin sublingual tablets. The practical nurse should reinforce which instruction?
- A. Store the tablets in a cool, dry place.
- B. Take one tablet every 5 minutes until pain is relieved, up to three tablets.
- C. Swallow the tablets whole.
- D. Chew the tablets for faster relief.
Correct answer: A
Rationale: Nitroglycerin sublingual tablets are sensitive to heat and moisture, so they should be stored in a cool, dry place to maintain their efficacy. Storing them in a cool, dry place helps prevent degradation of the medication. Choice B is incorrect because nitroglycerin tablets should be taken as directed by the healthcare provider to avoid potential overdose or adverse effects. Choice C is incorrect because sublingual tablets should be placed under the tongue to dissolve and be absorbed, not swallowed, to ensure their quick action. Choice D is incorrect because sublingual tablets should not be chewed; they are meant to be absorbed through the tissues under the tongue, and chewing them may alter their effectiveness.
4. A postoperative client has a prescription for ketorolac 30mg IV q6h. Which response demonstrates that therapeutic levels of the medication have been achieved?
- A. Observe wound drainage for a change in appearance
- B. Assess the client's calves for inflammation
- C. Perform a pain assessment using a numeric scale
- D. Measure the client's intake and output
Correct answer: C
Rationale: The correct response is to perform a pain assessment using a numeric scale. Ketorolac is an NSAID prescribed for pain relief. Monitoring pain levels is crucial to evaluate the therapeutic effectiveness of the medication. Pain assessment helps determine if the medication is providing adequate pain relief, indicating that therapeutic levels have been achieved.
5. What action should be taken six days after starting a prescription for oral amoxicillin solution?
- A. Determine if any other symptoms have developed
- B. Advise the use of over-the-counter antipyretics
- C. Instruct the client to increase oral fluid intake
- D. Ask if the medication has been kept refrigerated
Correct answer: A
Rationale: It is important to monitor for any new symptoms that may indicate a worsening condition or side effects when taking oral amoxicillin solution. This proactive approach helps in assessing the effectiveness and safety of the medication.
