HESI Practice Test Pharmacology
1. When planning to administer the antiulcer GI agent sucralfate, what instruction should the nurse provide regarding administration?
- A. Administer sucralfate once a day
- B. Assess for secondary candida infection
- C. Monitor electrolyte imbalance
- D. Give sucralfate on an empty stomach
Correct answer: D
Rationale: Sucralfate is most effective when taken on an empty stomach. This allows the medication to form a protective layer over the ulcer, promoting healing and symptom relief. Administering sucralfate with or after meals may reduce its efficacy as it may bind to food instead of coating the ulcer site.
2. According to a study in 2013 by van Gameren-Oosterom, individuals with Down syndrome:
- A. are unlikely to die from cardiovascular problems by middle age.
- B. have no specific characteristic features.
- C. show deficits in cognitive development.
- D. are likely to have only 46 chromosomes.
Correct answer: C
Rationale: The correct answer is C. According to a study in 2013 by van Gameren-Oosterom, individuals with Down syndrome often exhibit deficits in cognitive development. This is a common characteristic of Down syndrome, along with other health challenges. Choice A is incorrect because individuals with Down syndrome are at a higher risk of cardiovascular problems, contrary to being unlikely to die from them. Choice B is incorrect as Down syndrome is associated with specific characteristic features such as distinctive facial characteristics, making the statement that they have no specific features incorrect. Choice D is incorrect as individuals with Down syndrome have an extra copy of chromosome 21, resulting in a total of 47 chromosomes, not 46.
3. The nurse is teaching a group of parents about the side effects of immunization vaccines. Which sign should the nurse include when discussing an infant receiving the Haemophilus influenzae (Hib) vaccine?
- A. Lethargy
- B. Urticaria
- C. Generalized rash
- D. Low-grade fever
Correct answer: D
Rationale: The correct answer is 'D. Low-grade fever.' A low-grade fever is a common and mild side effect of the Hib vaccine, indicating that the immune system is responding to the immunization. Lethargy (choice A) can be a sign of more serious adverse effects and should be monitored closely but is not typically associated with the Hib vaccine. Urticaria (choice B) and generalized rash (choice C) are less common side effects of the Hib vaccine compared to low-grade fever.
4. A nurse working on a mental health unit receives a community call from a person who is tearful and states, 'I just feel so nervous all of the time. I don't know what to do about my problems. I haven't been able to sleep at night and have hardly eaten for the past 3 or 4 days.' The nurse should initiate a referral based on which assessment?
- A. Altered thought processes.
- B. Moderate levels of anxiety.
- C. Inadequate social support.
- D. Altered health maintenance.
Correct answer: B
Rationale: The nurse should initiate a referral based on moderate levels of anxiety (B) as the client reports feeling nervous all the time, sleep disturbances, poor appetite, and difficulty solving problems. These symptoms are indicative of significant anxiety levels. The client does not mention symptoms related to altered thought processes (A) or inadequate social support (C). There is insufficient information to suggest altered health maintenance (D) as a reason for referral in this scenario.
5. The nurse plans to help an 18-year-old female intellectually disabled client ambulate on the first postoperative day after an appendectomy. When the nurse tells the client it is time to get out of bed, the client becomes angry and tells the nurse, 'Get out of here! I'll get up when I'm ready!' Which response is best for the nurse to make?
- A. Your healthcare provider has prescribed ambulation on the first postoperative day.
- B. You must ambulate to avoid complications that could cause more discomfort than ambulating.
- C. I know how you feel. You're angry about having to ambulate, but this will help you get well.
- D. I'll be back in 30 minutes to help you get out of bed and walk around the room.
Correct answer: D
Rationale: (D) provides a 'cooling off' period, is firm, direct, non-threatening, and avoids arguing with the client. (A) is avoiding responsibility by referring to the healthcare provider. (B) is trying to reason with an intellectually disabled client and is threatening the client with 'complications.' (C) is telling the client how she feels (angry), and the nurse does not really 'know' how this client feels, unless the nurse is also intellectually disabled and has also just had an appendectomy.
