HESI Pharmacology Quizlet
1. A client is prescribed phenytoin (Dilantin) for seizure control. Which statement by the client indicates an understanding of the medication?
- A. I should brush and floss my teeth regularly.
- B. I should take the medication with antacids.
- C. I can stop taking the medication once my seizures are controlled.
- D. I should avoid drinking milk while taking this medication.
Correct answer: A
Rationale: The correct statement is 'I should brush and floss my teeth regularly.' Phenytoin (Dilantin) can cause gingival hyperplasia, so maintaining good oral hygiene is essential. Taking the medication with antacids can affect its absorption, so it should not be done. It is crucial not to stop taking the medication abruptly, even if seizures are controlled. There is no specific requirement to avoid milk while taking phenytoin (Dilantin).
2. A client receiving nitrofurantoin (Macrodantin) calls the health care provider's office complaining of side effects related to the medication. Which side effect indicates the need to stop treatment with this medication?
- A. Nausea
- B. Diarrhea
- C. Anorexia
- D. Cough and chest pain
Correct answer: D
Rationale: Pulmonary reactions such as cough and chest pain are serious side effects associated with nitrofurantoin that require immediate discontinuation of the medication to prevent potential severe respiratory complications.
3. Which bioterrorism agent is at high risk for use as a potential biological weapon that is readily transmitted by several portals of entry?
- A. anthrax
- B. smallpox
- C. botulism
- D. tularemia
Correct answer: A
Rationale: Anthrax is the correct answer. Anthrax spores can be transmitted through inhalation, ingestion, or skin contact, making it a high-risk agent for bioterrorism. Smallpox, botulism, and tularemia are also potential bioterrorism agents, but they do not have the same versatility in terms of multiple portals of entry, unlike anthrax.
4. A client with cirrhosis is admitted with jaundice and ascites. Which clinical finding is most concerning?
- A. Increased abdominal girth
- B. Confusion and altered mental status
- C. Yellowing of the skin
- D. Peripheral edema
Correct answer: B
Rationale: Confusion and altered mental status are concerning in a client with cirrhosis as they may indicate hepatic encephalopathy, a serious complication that requires immediate intervention. Increased abdominal girth can be seen in ascites, yellowing of the skin is due to jaundice, and peripheral edema is associated with fluid retention in cirrhosis, but confusion and altered mental status are more closely linked to hepatic encephalopathy, which can progress rapidly and needs urgent attention.
5. The nurse is assessing on the first postoperative day following thyroid surgery. Which laboratory value is most important for the nurse to monitor?
- A. Calcium
- B. Sodium
- C. Chloride
- D. Potassium
Correct answer: A
Rationale: Corrected Rationale: Monitoring calcium levels is crucial post-thyroid surgery to detect hypocalcemia, a common complication due to injury or removal of the parathyroid glands. Monitoring sodium, chloride, or potassium levels is not as vital in the immediate post-thyroid surgery period.
