HESI Practice Test Pharmacology
1. A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?
- A. Dilute the available heparin in 250ml of normal saline solution prior to IV administration
- B. Advise the pharmacy on the need to deliver a vial of heparin to the nursing unit immediately
- C. Calculate and administer the equivalent dose of the available low molecular weight heparin
- D. Request a prescription to change the route of administration and use the available heparin
Correct answer: B
Rationale: In this scenario, the nurse should contact the pharmacy to obtain the correct heparin formulation as the prescription calls for heparin 1,000 units IV STAT. Low molecular weight heparin is not the same as unfractionated heparin, and therefore, the nurse should not administer the available low molecular weight heparin without first obtaining the correct medication. Diluting the available heparin, calculating an equivalent dose, or changing the route of administration would not address the discrepancy between the prescribed heparin and the available low molecular weight heparin.
2. How do you determine if the medication is effective for a client with anemia secondary to chronic kidney disease (CKD)?
- A. Food diary shows increased consumption of iron-rich foods
- B. Reports of increased energy levels and decreased fatigue
- C. Hemoglobin level increased to 12 grams/dL
- D. Takes concurrent iron therapy without adverse effects
Correct answer: C
Rationale: The correct answer is C. To assess the effectiveness of medication for anemia in a client with CKD, monitoring hemoglobin levels is crucial. Hemoglobin levels directly indicate the response to treatment and improvement in the condition. An increase in hemoglobin level to 12 grams/dL suggests that the medication is effectively addressing the anemia associated with CKD. Choices A, B, and D are incorrect because increased consumption of iron-rich foods, reports of increased energy levels and decreased fatigue, and tolerance to concurrent iron therapy without adverse effects are not direct indicators of the medication's effectiveness in treating anemia secondary to CKD.
3. A client with diabetes mellitus type 1 is prescribed insulin lispro. When should the nurse instruct the client to administer this medication?
- A. 5-10 minutes before meals
- B. 15 minutes after meals
- C. 30 minutes before meals
- D. 1 hour after meals
Correct answer: A
Rationale: Corrected Rationale: Insulin lispro is a rapid-acting insulin that should be administered 5-10 minutes before meals. This timing helps synchronize the peak action of insulin with the rise in blood glucose levels after eating, effectively managing postprandial hyperglycemia. Choice B, administering 15 minutes after meals, is incorrect because rapid-acting insulins like lispro are meant to act quickly to cover the rise in blood glucose levels after meals. Choices C and D are also incorrect as they do not align with the rapid onset of action required to manage postprandial hyperglycemia in patients with diabetes mellitus type 1.
4. What is important information to provide to a young adult female client planning to become pregnant?
- A. Discontinue this medication one month before.
- B. Breastfeeding is not recommended while.
- C. Baseline liver function results must be obtained.
- D. Do not take multiple vitamins that contradict.
Correct answer: A
Rationale: It is crucial to advise the client to discontinue medication one month before planning to become pregnant to prevent potential harm to the fetus. This precaution is essential as certain medications can have adverse effects on the developing baby. By stopping the medication ahead of time, the client can reduce the risk of any complications during pregnancy.
5. A client with type 2 diabetes mellitus is prescribed exenatide. The nurse should monitor for which potential adverse effect?
- A. Nausea
- B. Hypoglycemia
- C. Hyperglycemia
- D. Pancreatitis
Correct answer: A
Rationale: Exenatide, a medication commonly used in type 2 diabetes, is known to cause gastrointestinal side effects, such as nausea. Monitoring for nausea is essential as it can lead to decreased appetite and potential weight loss, affecting the nutritional status of the client. While hypoglycemia and hyperglycemia are important to monitor in diabetes management, they are not typically associated with exenatide use. Pancreatitis is a rare but serious adverse effect of exenatide, which requires immediate medical attention if suspected.
