The nurse receives an order to draw a peak level on a patient prescribed Gentamicin via Intravenous (IV) infusion. When is the best time for the nurse to draw this peak level?

Respiratory acidosis is a primary acid-base imbalance that occurs when there is an excess of carbon dioxide (CO2) in the body due to impaired ventilation or inadequate removal of CO2 from the lungs. In this case, Colleen's depressed ventilation, indicated by shallow and slow respirations, can lead to inadequate elimination of CO2 from her body. The excessive CO2 levels can result in an accumulation of carbonic acid (H2CO3) in the blood, leading to an increase in acidity and a decrease in pH.

The profuse bleeding from both ears indicates a potential head injury, which can lead to decreased neurological function and impaired control over the respiratory center in the brain. This can further contribute to depressed ventilation and the development of respiratory acidosis. Metabolic acidosis, characterized by a decrease in bicarbonate (HCO3-) levels or an increase in non-carbonic acids in the blood, is not the primary acid-base imbalance in this case since the scenario does not provide information indicating a primary metabolic disorder. Respiratory alkalosis, characterized by decreased levels of CO2 in the blood, leading to increased pH and alkalinity, is not the primary acid-base imbalance in this case. The depressed ventilation and associated increase in CO2 levels indicate the opposite, respiratory acidosis. Metabolic alkalosis, characterized by an increase in bicarbonate levels or a decrease in non-carbonic acids, is not the primary acid-base imbalance in this case as the scenario does not provide information indicating a primary metabolic disorder.

Loop diuretics, such as furosemide, are known to promote diuresis (increased urine output) and can cause electrolyte imbalances, including low potassium (hypokalemia). The patient's statement about eating a diet rich in potassium-containing foods like potatoes, bananas, avocadoes, strawberries, and spinach is incorrect in this context. These foods are indeed good sources of potassium, but when taking loop diuretics, it is necessary to monitor and potentially restrict potassium intake to prevent excessive potassium levels.

"I will weigh myself daily and report to my physician if I gain more than 3 lbs in 1 day." This statement reflects the patient's understanding of the need to monitor their weight daily as a means of assessing fluid balance. Rapid weight gain may indicate fluid retention, which should be reported to the physician.

"This medication can cause dehydration, so I will stay hydrated by consuming at least 2 L or more of fluid per day." This statement demonstrates awareness of the potential for dehydration when taking loop diuretics and the importance of staying adequately hydrated by consuming an appropriate amount of fluids.

"I will change position slowly because I can become dizzy easily while taking this medication." This statement reflects the understanding that loop diuretics can cause orthostatic hypotension,

leading to dizziness upon sudden changes in position. Taking precautions and changing position slowly can help prevent falls and related injuries.
