1. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?

Correct answer: A

Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.

2. A client with chronic renal disease is receiving therapy with epoetin alfa. Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?

Correct answer: C

Rationale: The correct answer is C: The hematocrit (Hct). Monitoring the hematocrit is essential to assess the therapeutic effect of epoetin alfa because this medication stimulates red blood cell production in clients with chronic renal disease. The leukocyte count (choice A) and platelet count (choice B) are not directly affected by epoetin alfa therapy. The erythrocyte sedimentation rate (ESR) (choice D) is a non-specific marker of inflammation and is not used to monitor the therapeutic effect of epoetin alfa.

3. A healthcare professional is reviewing laboratory findings and notes that a client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the healthcare professional?

Correct answer: A

Rationale: Performing immediate gastric lavage is the appropriate action for a client with severe lithium toxicity, indicated by a plasma lithium level of 2.1 mEq/L. Gastric lavage can help reduce the client's lithium level by removing the unabsorbed drug from the stomach.

4. When reviewing a client's health record, a nurse notes a new prescription for Lisinopril 10 mg PO once daily. The nurse should identify this as which type of prescription?

Correct answer: C

Rationale: A routine prescription indicates medications to be administered on a regular schedule without a termination date or a specific number of doses. In this case, Lisinopril 10 mg PO once daily falls under a routine prescription, meaning the nurse will administer this medication daily until the provider discontinues it. Choices A, B, and D are incorrect: A 'single' prescription is for a one-time dose, 'stat' prescriptions are for immediate administration, and 'standing' prescriptions are pre-authorized for administration as needed within specified parameters.

5. A healthcare professional is educating a client about the adverse effects of Metformin. Which of the following adverse effects should the healthcare professional include?

Correct answer: A

Rationale: The correct answer is A: Lactic acidosis. Lactic acidosis is a rare but severe side effect of Metformin, particularly in individuals with renal or liver issues. It is crucial for clients taking Metformin to be aware of the symptoms of lactic acidosis, such as muscle pain, weakness, trouble breathing, stomach discomfort, and feeling cold. Choice B, hypoglycemia, is not a common adverse effect of Metformin but can occur when combined with other antidiabetic medications. Choice C, hyperlipidemia, is not a typical adverse effect of Metformin. Choice D, weight gain, is not associated with Metformin use; in fact, Metformin is often associated with weight loss or weight neutrality.
