HESI Pharmacology Practice Exam
1. A postoperative client has received a dose of naloxone hydrochloride for respiratory depression shortly after transfer to the nursing unit from the postanesthesia care unit. After administration of the medication, the nurse checks the client for:
- A. Pupillary changes
- B. Scattered lung wheezes
- C. Sudden increase in pain
- D. Sudden episodes of diarrhea
Correct answer: C
Rationale: Naloxone hydrochloride is an antidote to opioids and may be administered to postoperative clients to address respiratory depression. This medication can also reverse the effects of analgesics, potentially leading to a sudden increase in pain. Therefore, the nurse must assess the client for any unexpected rise in pain levels after naloxone administration. Choices A, B, and D are incorrect because pupillary changes, scattered lung wheezes, and sudden episodes of diarrhea are not typically associated with naloxone administration for respiratory depression.
2. A client is receiving meperidine (Demerol) for pain management. Which assessment finding requires immediate action?
- A. Constipation
- B. Drowsiness
- C. Respiratory rate of 10 breaths per minute
- D. Nausea
Correct answer: C
Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a severe side effect of meperidine (Demerol) that necessitates immediate intervention to prevent further complications. Constipation, drowsiness, and nausea are common but less urgent side effects that do not pose an immediate life-threatening risk. Respiratory depression can lead to respiratory arrest and must be addressed promptly to ensure the client's safety and well-being.
3. Which of the following herbal therapies would be prescribed for its use as an antispasmodic? Select all that apply.
- A. Aloe
- B. Kava
- C. Ginger
- D. Chamomile
Correct answer: D
Rationale: Chamomile is known for its antispasmodic properties. It helps in relaxing muscles and reducing spasms. Aloe is a laxative, kava has anxiolytic and sedative effects, and ginger is commonly used to relieve nausea.
4. Tamoxifen is prescribed for the client with metastatic breast carcinoma. The nurse understands that the primary action of this medication is to:
- A. Increase DNA and RNA synthesis.
- B. Promote the biosynthesis of nucleic acids.
- C. Increase estrogen concentration and estrogen response.
- D. Compete with estradiol for binding to estrogen in tissues containing high concentrations of receptors.
Correct answer: D
Rationale: The primary action of tamoxifen, an antineoplastic medication used in metastatic breast carcinoma, is to compete with estradiol for binding to estrogen receptors in tissues with high receptor concentrations. By doing so, tamoxifen reduces DNA synthesis and estrogen response, leading to its therapeutic effect in inhibiting the growth of estrogen-sensitive breast cancer cells.
5. A client is to begin a 6-month course of therapy with isoniazid (INH). A nurse plans to teach the client to:
- A. Avoid drinking alcohol.
- B. Report yellow eyes or skin immediately.
- C. Avoid Swiss or aged cheeses.
- D. Avoid vitamin supplements during therapy.
Correct answer: B
Rationale: When a client is on isoniazid (INH) therapy, they should be instructed to report any signs of hepatitis, such as yellowing of the eyes or skin, immediately. Alcohol consumption should be avoided during INH therapy due to the risk of hepatotoxicity. Foods high in tyramine, such as Swiss or aged cheeses, should also be avoided to prevent adverse reactions. Additionally, while on INH therapy, it is essential to avoid vitamin supplements containing pyridoxine (vitamin B6) to prevent potential interactions.
