The healthcare provider (HCP) prescribes cefuroxime 1.5 grams every 8 hours IM for a client with pneumonia. The available vial is labeled, "Cefuroxime 500 mg/mL." How many mL should the nurse administer to this client?

(Enter numerical value only. If rounding is required, round to the nearest whole number.)

Potential Conditions

Anemia: Anemia commonly causes fatigue and weakness, but it does not typically explain diarrhea. Additionally, the use of spironolactone, a potassium-sparing diuretic, makes electrolyte imbalance a more likely cause of these symptoms rather than anemia.

Hepatic failure: While hepatic failure could cause fatigue and systemic symptoms, it usually presents with jaundice, ascites, or confusion in advanced cases. There are no signs of liver-related symptoms in this scenario, making hepatic failure less likely.

Hyperkalemia: Hyperkalemia is the most likely condition because spironolactone can cause potassium retention. Symptoms such as fatigue, muscle weakness, and gastrointestinal disturbances like diarrhea are classic early signs of elevated potassium levels.

Hyperuricemia: Hyperuricemia is characterized by elevated uric acid levels, often leading to gout attacks rather than gastrointestinal symptoms or muscle weakness. Therefore, it is not the primary concern with this client’s current presentation.

Actions to take

Check the client's oxygen saturation: Although oxygen saturation is important in many acute settings, the client’s symptoms suggest a metabolic issue rather than a respiratory problem. Checking oxygenation would not directly address suspected hyperkalemia.

Do a point of care glucose check: Checking glucose is appropriate for clients with symptoms of hyperglycemia or hypoglycemia, but this client’s symptoms and medication history point more toward an electrolyte imbalance rather than a glucose-related disorder.

Measure the client's abdominal girth: Measuring abdominal girth is useful for detecting fluid accumulation, such as ascites in liver failure, but it is not relevant in the assessment of hyperkalemia. It would not provide information needed for the client’s immediate concern.

Ask the client about their diet: Dietary habits, particularly potassium intake, can significantly impact potassium levels when using potassium-sparing medications like spironolactone. Understanding the client's diet can help identify factors contributing to hyperkalemia.

Do a blood chemistry panel: A blood chemistry panel would provide critical information about serum electrolytes, including potassium levels. It is essential for diagnosing and confirming hyperkalemia and guiding further treatment decisions.

Parameters to Monitor

Edema: While edema monitoring is important in some chronic conditions like heart failure, it is not a primary concern with hyperkalemia. Hyperkalemia affects muscle and cardiac conduction, not typically fluid balance or peripheral swelling.

Skin color: Monitoring skin color can reveal perfusion issues but does not directly help detect or manage hyperkalemia. Changes in skin color would not provide early or specific warning signs of worsening potassium levels.

Pedal pulses: Pedal pulses are useful in assessing circulatory problems such as peripheral arterial disease but are not directly related to the cardiac conduction disturbances seen in hyperkalemia. Focus should instead be on heart rhythm.

Potassium level: Potassium level monitoring is essential because hyperkalemia can progress quickly and lead to life-threatening cardiac complications. Keeping track of potassium levels helps assess the severity of the imbalance and the response to treatment.

Heart Rhythm: Monitoring heart rhythm is critical, as hyperkalemia can cause bradycardia, peaked T waves, and even cardiac arrest. Continuous cardiac monitoring allows for early detection of dangerous arrhythmias resulting from elevated potassium.

A. Schedule the medication to be given just before bedtime: Pyridostigmine should be timed to coincide with periods of increased activity, especially before meals, to improve muscle strength. Giving it at bedtime would not offer functional benefit unless the client experiences nighttime symptoms.

B. Break the medication into small pieces and sprinkle onto food: Pyridostigmine tablets are not designed to be crushed or split unless specifically directed. Altering the form may affect its absorption and reduce its effectiveness in managing symptoms of myasthenia gravis.

C. Instruct the client to avoid dairy products for at least 30 minutes: Dairy does not interfere significantly with the absorption or action of pyridostigmine. Dietary restrictions should be based on known drug-food interactions, which are not typically associated with pyridostigmine and dairy.

D. Administer the medication thirty minutes prior to meals: Administering pyridostigmine before meals helps enhance swallowing and chewing abilities, reducing the risk of aspiration. This timing optimizes muscle strength during eating, which is a high-risk activity for clients with myasthenia gravis.
