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 A

Explanation

A. "STAT" stands for "immediately" or "at once" in medical terminology. When a medication order is marked as STAT, it means that the medication should be administered as soon as possible, without delay. This abbreviation is used for urgent situations where the medication needs to be given promptly.
B. "PRN" stands for "pro re nata," which translates to "as needed" in Latin. When a medication order is marked as PRN, it means that the medication should be administered as required based on the patient's needs or symptoms. The timing of administration is not fixed but depends on specific conditions or situations, such as pain or nausea.
C. "TID" stands for "ter in die," which translates to "three times a day" in Latin. When a medication order is marked as TID, it means that the medication should be administered three times daily, at regular intervals throughout the day.
D. "QID" stands for "quater in die," which translates to "four times a day" in Latin. When a medication order is marked as QID, it means that the medication should be administered four times daily, at regular intervals throughout the day.

A. metabolic alkalosis. B. respiratory alkalosis. C. metabolic acidosis. D. respiratory acidosis.

Correct Answer is A

Explanation

A. Metabolic alkalosis is characterized by an elevation of the bicarbonate (HCO3) levels in the blood, leading to an increase in pH above the normal range (7.35-7.45). Antacid tablets typically contain compounds such as calcium carbonate, magnesium hydroxide, or aluminum hydroxide, which can neutralize stomach acid (hydrochloric acid). Chronic ingestion of large amounts of antacids, as in the case of this client taking approximately 15 tablets per day, can result in excessive bicarbonate intake, leading to metabolic alkalosis.
B. Respiratory alkalosis occurs when there is a decrease in carbon dioxide (CO2) levels in the blood, leading to an increase in pH above the normal range. Antacid tablets do not directly affect respiratory function or CO2 levels, so respiratory alkalosis is unlikely to occur as a result of antacid ingestion.
C. Metabolic acidosis is characterized by a decrease in bicarbonate (HCO3) levels in the blood, leading to a decrease in pH below the normal range. In the context of antacid ingestion, metabolic acidosis is less likely to occur. However, if the antacids contain compounds that are absorbed systemically and excreted by the kidneys (such as aluminum-containing antacids), they may lead to renal dysfunction or electrolyte imbalances, which could potentially contribute to metabolic acidosis.
D. Respiratory acidosis occurs when there is an increase in carbon dioxide (CO2) levels in the blood, leading to a decrease in pH below the normal range. Antacid tablets do not directly affect respiratory function or CO2 levels, so respiratory acidosis is unlikely to occur as a result of antacid ingestion.
