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?

30 minutes before starting the infusion.

30 minutes after infusion is complete

Immediately before the next dose of Gentamicin

1 hour after infusion is complete

Answer and Explanation

The Correct Answer is B

Gentamicin is an antibiotic that is usually administered via IV infusion. The peak level is the highest concentration of the medication in the bloodstream, and it is important to monitor it to ensure therapeutic levels are achieved without reaching toxic levels.

Drawing the peak level 30 minutes after the infusion is complete allows enough time for the medication to distribute throughout the body and reach its peak concentration. This timing provides an accurate representation of the highest drug concentration in the bloodstream. 30 minutes before starting the infusion: Drawing the peak level before starting the infusion would not accurately reflect the peak concentration of the medication in the bloodstream. Immediately before the next dose of Gentamicin: Drawing the peak level immediately before the next dose would not provide an accurate assessment of the highest drug concentration, as the levels would have started to decrease due to elimination.

1 hour after infusion is complete: Waiting for 1 hour after the infusion is complete may result in missing the actual peak concentration of the medication in the bloodstream, as it may have already started to decline.

Correct Answer is ["C","D","E"]

Explanation

Crackles and wheezing indicate the presence of excessive mucus or secretions in the airways, which may require suctioning to clear the airway and improve breathing.

The presence of serosanguineous drainage on the tracheostomy dressing may indicate increased mucus production or bleeding, suggesting the need for suctioning to remove secretions or assess for any bleeding complications.

Regular suctioning is necessary to maintain a patent airway for patients with a tracheostomy. If suctioning was performed more than 4 hours ago, it may be time for another suctioning session to prevent the accumulation of secretions and maintain airway clearance. While a fever may indicate an underlying infection or inflammation, it does not specifically indicate the need for suctioning. The decision to suction should be based on the patient's respiratory assessment and the presence of respiratory symptoms.

While patient requests and preferences are important, the need for suctioning should be determined based on clinical indicators and assessment findings rather than solely relying on patient requests.

A. Uncompensated Respiratory Acidosis B. Fully Compensated Metabolic Acidosis C. Uncompensated Metabolic Alkalosis D. Partially Compensated Respiratory Alkalosis

Correct Answer is C

Explanation

The pH value of 7.5 indicates alkalosis, as it is above the normal range of 7.35-7.45. The elevated bicarbonate (HCO3-) level of 34 mmol/L suggests metabolic alkalosis, as it is higher than the normal range of 22-28 mmol/L. The PaCO2 level of 40 mm Hg falls within the normal range of 35-45 mm Hg.

In this case, the primary disturbance is metabolic alkalosis, which is likely caused by the persistent vomiting leading to excessive loss of gastric acid (hydrogen ions) and chloride ions from the stomach. This loss of acid and chloride results in an imbalance of electrolytes and an increase in bicarbonate levels, leading to metabolic alkalosis.

Since there is no significant deviation from the normal range in the PaCO2 level, the respiratory system has not effectively compensated for the metabolic alkalosis. Therefore, it is considered uncompensated.
