A nurse is caring for a client who has a new prescription for metformin. Which of the following laboratory results should the nurse evaluate prior to administering the first dose?
Potassium level
Creatinine level
Platelet count
Liver enzymes
The Correct Answer is B
Before administering the first dose of metformin, the nurse should evaluate the client's creatinine level. Metformin is primarily excreted by the kidneys, and its clearance from the body depends on the renal function. If the client has impaired kidney function, metformin can accumulate in the body and lead to potential adverse effects, particularly lactic acidosis.
Monitoring the creatinine level helps assess the client's kidney function and determines whether it is safe to administer metformin. If the creatinine level is elevated, indicating reduced kidney function, the nurse should consult with the healthcare provider to determine the appropriate dose adjustment or consider an alternative treatment option.
Let's go through the other options and explain why they are not the priority laboratory results to evaluate before administering metformin:
A. Potassium level: While monitoring potassium levels is important in some situations, it is not a primary concern before administering metformin. Metformin does not have a significant effect on potassium levels, and it is not a medication known for causing hypokalemia (low potassium levels).
C. Platelet count: Metformin does not have a direct impact on platelet count, and evaluating platelet count is not typically required before starting metformin therapy. Platelet count monitoring may be relevant for certain other medications or medical conditions, but it is not specific to metformin administration.
D. Liver enzymes: While it is essential to monitor liver function in clients on long-term metformin therapy, evaluating liver enzymes before the first dose of metformin is not the priority. Metformin is primarily cleared by the kidneys, and liver enzymes are not directly affected by its initial administration. However, ongoing monitoring of liver function may be necessary during long-term

Correct Answer is C
Explanation
Smoking is a known risk factor for the development of aspirin-induced ulcers. It can increase the risk of gastrointestinal bleeding and compromise the integrity of the gastric mucosa. Smoking can also impair the healing process and increase the risk of complications associated with ulcers.
While the other factors mentioned in the options may have their own health implications, smoking is specifically associated with an increased risk of aspirin-induced ulcers. Therefore, the nurse should identify the client's smoking habit as a risk factor for the development of an aspirin-induced ulcer.
Correct Answer is C
Explanation
Flumazenil is the antidote for diazepam, which is a benzodiazepine. Flumazenil is a selective antagonist that can reverse the sedative effects of benzodiazepines and is commonly used in cases of benzodiazepine overdose or to reverse sedation after procedures.
Naloxone (A) is the antidote for opioid overdose and would not be appropriate for reversing the effects of diazepam.
Atropine (B) is an anticholinergic medication used to increase heart rate and is not specific to the reversal of diazepam sedation.

Neostigmine (D) is a cholinesterase inhibitor used to reverse the effects of non-depolarizing neuromuscular blocking agents and is not indicated for reversing the effects of diazepam.
