A client will require IV antibiotics for several weeks. Which venous access device would be most appropriate to be used for this client?

a butterfly needle

a peripherally inserted central catheter

a peripheral IV-lock

a small gauge (16g) peripheral anglocath

Answer and Explanation

The Correct Answer is B

B. A PICC line is a long, flexible catheter inserted into a peripheral vein, typically in the upper arm, and advanced until the tip lies in the superior vena cava or the cavoatrial junction. PICC lines are suitable for long-term venous access and are often used for administering medications, including antibiotics, over several weeks or months. They offer stable and reliable access, reducing the need for frequent venipunctures.

A. Butterfly needles are typically used for short-term venous access, such as for blood draws or administering medications that do not require long-term therapy. They are not suitable for prolonged use or for administering medications over several weeks, as they are not designed for secure and stable access over an extended period.
C. A peripheral IV-lock, also known as a saline lock or heplock, is a short catheter inserted into a peripheral vein and then capped off for intermittent use. While peripheral IV-locks are suitable for short-term venous access, they are not ideal for prolonged therapy lasting several weeks. Additionally, they may not provide the necessary stability and reliability for administering IV antibiotics over an extended period.
D. A small gauge peripheral angiocath refers to a short catheter inserted into a peripheral vein for intravenous access. While a larger gauge catheter, such as a 16-gauge, may allow for faster infusion rates and is suitable for certain situations requiring rapid fluid administration, it may not be the most appropriate choice for long-term IV antibiotic therapy. The choice of gauge depends on factors such as the client's vein size, the viscosity of the medication, and the duration of therapy.

Correct Answer is C

Explanation

C. Full compensation typically occurs within 2 to 3 days (approximately 72 hours) after the onset of an acid-base disturbance. During full compensation, the primary acid-base disorder (e.g., respiratory acidosis or alkalosis, metabolic acidosis or alkalosis) is still present, but the compensatory mechanisms have effectively brought the pH, pCO2, and bicarbonate (pHCO3) levels back towards normal range.
A. Full compensation occurs when both the primary disorder (respiratory or metabolic) and the compensatory mechanism (renal or respiratory) are functioning to return the pH towards normal. In this option, while the pO2 is within the normal range, the pH, pCO2, and bicarbonate (pHCO3) are all abnormal, indicating an ongoing imbalance.
B. Full compensation occurs when all components of the ABG are within or approaching normal range, indicating that the body's compensatory mechanisms have effectively counteracted the primary acid- base disturbance. In this option, the bicarbonate (pHCO3) is mentioned as starting to change, indicating incomplete compensation.
D. While the pH is within the normal range, both the pCO2 and pO2 are abnormal, indicating a primary respiratory disturbance. In the case of full compensation, the pH, pCO2, and bicarbonate (pHCO3) levels would all be within or approaching normal range, indicating that the compensatory mechanisms have effectively counteracted the primary acid-base disturbance.

A. give the recommended dose of the medication based on the client's diagnosis B. Hold the ordered dose & document their rationale regarding the dose. C. Call the pharmacy to report a mistake D. Call the prescribing physician to clarify the order

Correct Answer is D

Explanation

D. Calling the prescribing physician to clarify the order is the most appropriate action in this situation. Direct communication with the physician allows the nurse to express concerns, seek clarification, and ensure that the medication order is appropriate and safe for the client.
A. Administering a medication at a higher than recommended dose could potentially harm the client and is not in line with safe medication administration practices. It's essential to follow the established guidelines and recommendations for medication dosing to avoid adverse effects or complications.
B. Holding the ordered dose and documenting the rationale is an appropriate initial action. This allows the nurse to pause the administration of the medication, prevent potential harm to the client, and provide a clear record of the decision-making process. Holding the dose also provides an opportunity for further clarification with the prescribing physician.
C. While reporting a mistake to the pharmacy is important, it may not be the most immediate action to take when dealing with a higher than recommended dose of medication. Direct communication with the prescribing physician is necessary to clarify the order and ensure appropriate action is taken promptly.
