HESI Pharmacology Practice Exam
1. The clinic nurse is reviewing a teaching plan for a client receiving antineoplastic medication. When implementing the plan, the nurse should advise the client:
- A. To take aspirin (acetylsalicylic acid) as needed for a headache
- B. To avoid drinking beverages containing alcohol
- C. To consult with healthcare providers (HCPs) before receiving immunizations
- D. That it is necessary to consult HCPs before receiving a flu vaccine at the local health fair
Correct answer: C
Rationale: The correct advice for a client receiving antineoplastic medication is to consult with healthcare providers (HCPs) before receiving immunizations. Antineoplastic medications can lower the body's resistance, making it crucial to seek guidance from healthcare providers to prevent potential complications that may arise due to the medication's impact on the immune system. Choices A, B, and D are incorrect because taking aspirin for a headache, avoiding alcohol, and consulting only before a flu vaccine at a local health fair do not directly address the specific risk related to antineoplastic medications and immunizations.
2. A client receives a prescription for methocarbamol (Robaxin), and the nurse reinforces instructions to the client regarding the medication. Which client statement would indicate a need for further instructions?
- A. My urine may turn brown or green.
- B. This medication is prescribed to help relieve my muscle spasms.
- C. If my vision becomes blurred, I need to be concerned about it.
- D. I need to call my doctor if I experience nasal congestion from this medication.
Correct answer: C
Rationale: The correct answer is C because blurred vision is an adverse effect of methocarbamol (Robaxin) and should be reported to a healthcare provider. Choices A, B, and D are all correct statements. Option A informs the client about a possible discoloration of urine, which is a known side effect. Option B correctly explains the purpose of the medication. Option D correctly advises the client to contact their doctor if they experience nasal congestion, which could indicate an adverse reaction.
3. A client taking fexofenadine (Allegra) is scheduled for allergy skin testing and tells the nurse in the healthcare provider's office that a dose was taken this morning. The nurse determines that:
- A. The client should reschedule the appointment.
- B. A lower dose of allergen will need to be injected.
- C. A higher dose of allergen will need to be injected.
- D. The client should have the skin test read a day later than usual.
Correct answer: A
Rationale: Fexofenadine, an antihistamine, can cause false-negative readings in allergy skin testing and should be discontinued 3 days prior. Therefore, the client should reschedule the appointment to ensure accurate test results.
4. A healthcare professional is preparing to administer an intramuscular dose of penicillin to a client with a history of anaphylactic reactions to penicillin. Which action should the healthcare professional take first?
- A. Check the medication order for accuracy.
- B. Have an epinephrine injection available.
- C. Administer a test dose to check for a reaction.
- D. Ask the client about any allergies.
Correct answer: B
Rationale: When dealing with a client who has a history of anaphylactic reactions to penicillin, the priority action for the healthcare professional is to have an epinephrine injection readily available in case of a severe allergic reaction. In such cases, the immediate focus is on being prepared to manage a potentially life-threatening situation. While checking the medication order for accuracy, administering a test dose, and asking the client about allergies are essential steps in medication administration, the first priority is ensuring the availability of epinephrine to address a severe allergic reaction promptly.
5. Why is prostaglandin E1 prescribed for a child with transposition of the great arteries?
- A. Prevents hypercyanotic (blue or tet) spells
- B. Maintains an adequate hormone level
- C. Maintains the position of the great arteries
- D. Provides adequate oxygen saturation and maintains cardiac output
Correct answer: D
Rationale: Prostaglandin E1 is prescribed for a child with transposition of the great arteries to increase blood mixing, which helps maintain adequate oxygen saturation and cardiac output. This medication does not prevent hypercyanotic spells, maintain hormone levels, or influence the position of the great arteries.
