HESI Practice Test Pharmacology
1. A client prescribed glipizide asked why they had to take their insulin orally. How should the practical nurse respond?
- A. Glipizide is not an oral form of insulin and can be used only when some beta cell function is present.
- B. Glipizide is an oral form of insulin and is distributed, metabolized, and excreted in the same manner as insulin.
- C. Glipizide is an oral form of insulin and has the same actions and properties as intermediate insulin.
- D. Glipizide is not an oral form of insulin, but it is effective for those who are resistant to injectable insulins.
Correct answer: A
Rationale: The practical nurse should explain to the client that glipizide is not an oral form of insulin but an oral hypoglycemic agent. Glipizide works by enhancing pancreatic production of insulin when some beta cell function is present. It is not a replacement for insulin but helps the body produce more insulin. Therefore, it can be used when there is still some beta cell function present, unlike insulin which is used when there is a deficiency of endogenous insulin production.
2. A client with asthma is prescribed fluticasone. The nurse should instruct the client to use this medication at which time?
- A. During an asthma attack
- B. Twice a day
- C. Once a day
- D. At night before bed
Correct answer: C
Rationale: Fluticasone is a maintenance medication for asthma aimed at controlling symptoms. It should be taken once a day on a regular basis to provide ongoing relief and prevent asthma symptoms, rather than being used to treat acute asthma attacks. Therefore, the correct answer is to use it once a day. Choices A, B, and D are incorrect because using fluticasone during an asthma attack, twice a day, or only at night before bed does not align with the medication's purpose of being a daily maintenance therapy.
3. Phenazopyridine is commonly prescribed for clients with urinary tract infections (UTI). Which statement by the practical nurse describes the purpose for the administration of phenazopyridine?
- A. To alter the pH level of the urine
- B. To reduce the frequency of bladder spasms
- C. To alleviate the painful symptoms caused by the UTI
- D. To prevent bacterial replication and resistance development
Correct answer: C
Rationale: The correct answer is C. Phenazopyridine, a urinary analgesic, is utilized to alleviate the pain associated with urinary tract infections (UTIs) like burning, pain, urgency, and frequent voiding. The administration of phenazopyridine can cause the urine to turn a bright red-orange color. It is recommended to take this medication with food to reduce gastric irritation. Phenazopyridine should only be used for a maximum of 2 days when taken alongside an antibacterial agent, which is typically prescribed for about 2 weeks to treat the underlying infection.
4. The patient is prescribed cimetidine (Tagamet) orally. What should the nurse consider about administering this drug?
- A. Administer the drug with the first bite of food
- B. Administer the drug immediately after meals
- C. Administer the drug 30 minutes after meals
- D. Administer the drug 30 minutes before meals
Correct answer: D
Rationale: Cimetidine is best absorbed when taken 30 minutes before meals to decrease stomach acid. Administering it before meals allows for optimal absorption and effectiveness of the medication. Choices A, B, and C are incorrect because administering cimetidine with food, immediately after meals, or 30 minutes after meals may not provide the best conditions for absorption. Taking it before meals ensures that the drug is absorbed properly and can exert its intended effects.
5. A client with hypertension is prescribed metoprolol. The healthcare provider should monitor the client for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Hyperglycemia
- D. Hyponatremia
Correct answer: A
Rationale: Metoprolol is a beta-blocker that works by slowing the heart rate and reducing blood pressure. One of the potential side effects of metoprolol is bradycardia, which is a slow heart rate. Monitoring for bradycardia is crucial as it can be an adverse effect of this medication.
