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

Answer and Explanation

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.

A. Azithromycin B. Tetracycline C. Cefuroxime D. Gentamicin

Correct Answer is B

Explanation

A nurse who is caring for a preschooler should question a prescription for tetracycline. Tetracycline is contraindicated in children under 8 years of age due to its potential to cause permanent discoloration and damage to developing teeth and bones. This adverse effect is known as tooth staining or dental hypoplasia.

Let's go through the other options:

A. Azithromycin: Azithromycin is an appropriate antibiotic for use in preschool-age children and is commonly prescribed for various bacterial infections. It does not pose the same risk of tooth staining as tetracycline, making it a safe option for this age group.

C. Cefuroxime: Cefuroxime is another antibiotic that is safe for use in preschoolers. It belongs to the cephalosporin class of antibiotics and is commonly prescribed for respiratory tract infections, skin infections, and other bacterial infections.

D. Gentamicin: While gentamicin is an effective antibiotic, its use in preschool-age children should be carefully monitored. Gentamicin can have potential ototoxic and nephrotoxic effects (damage to the inner ear and kidneys, respectively). However, its use is not strictly contraindicated in this age group, and it can be prescribed when necessary with appropriate monitoring.
