Pharmacology HESI 55 Questions 2023
1. A client who takes metformin for diabetes mellitus type 2 is nothing by mouth (NPO) for surgery. What pre-op prescription should the practical nurse (PN) anticipate for this client's glucose management?
- A. NPO except for metformin and regular snacks
- B. NPO except for oral antidiabetic agent
- C. Novolin-N insulin subcutaneously twice daily
- D. Regular insulin subcutaneously per sliding scale
Correct answer: D
Rationale: When a client taking metformin for diabetes mellitus type 2 is NPO for surgery, it is crucial to manage their glucose levels effectively. The best approach in this situation is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications. Choices A and B are incorrect because metformin is typically held when a client is NPO, and oral antidiabetic agents may not provide sufficient glucose control. Choice C is incorrect as Novolin-N insulin given twice daily may not offer the flexibility needed for glucose management in a surgical setting where the client's intake is restricted.
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. A client with a diagnosis of bipolar disorder is prescribed valproate. The nurse should monitor for which potential adverse effect?
- A. Weight gain
- B. Hair loss
- C. Hyperglycemia
- D. Hypoglycemia
Correct answer: A
Rationale: The correct answer is A: Weight gain. Valproate is known to cause weight gain as a common adverse effect. It is important for the nurse to monitor the client's weight regularly while on this medication to detect and address any changes that may occur.
4. A patient is prescribed sucralfate (Carafate) and asks the nurse what the purpose of taking this medication is. Which is the nurse's best response?
- A. The medication helps reduce bacteria levels in the stomach
- B. The medication helps neutralize gastric acid in the stomach
- C. The medication is used to protect the gastrointestinal mucosa
- D. The medication can reduce the patient's constipation
Correct answer: C
Rationale: The correct answer is C. Sucralfate (Carafate) is used to protect the gastrointestinal mucosa by forming a protective barrier over ulcers. This barrier helps prevent stomach acid from further damaging the ulcers and promotes healing. It does not directly reduce bacteria levels, neutralize gastric acid, or have a direct effect on constipation.
5. A client with a history of atrial fibrillation is prescribed digoxin. The nurse should monitor for which sign of digoxin toxicity?
- A. Bradycardia
- B. Tachycardia
- C. Nausea
- D. Vomiting
Correct answer: A
Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin, a medication used to treat atrial fibrillation, can lead to toxicity manifesting as various cardiac dysrhythmias, with bradycardia being a notable indicator. Monitoring for bradycardia is crucial as it can indicate the need for dosage adjustment or discontinuation of digoxin to prevent adverse effects. Tachycardia, nausea, and vomiting are not typically associated with digoxin toxicity, making them incorrect choices for monitoring in a client receiving this medication.
