The nurse is preparing discharge teaching for a client newly diagnosed with cancer who just had a tunneled IV catheter (Hickman) placed. The nurse would include which information in the teaching plan regarding sign and symptoms of infection?

Notify the primary care provides with increased urine output

Assess daily for redness. swelling or exudate at insertion site weekly

The primary care provider will monitor hemoglobin and a hematocrit values

To maintain patency, the catheter should be flushed weekly using at 5ml syringe

Answer and Explanation

The Correct Answer is B

A) Notify the primary care provider with increased urine output
Increased urine output is not directly related to signs or symptoms of infection associated with a tunneled IV catheter, such as a Hickman catheter. While changes in urinary output might indicate renal or other systemic issues, they do not signal a local infection at the insertion site.

B) Assess daily for redness, swelling, or exudate at insertion site weekly
One of the most common complications of a tunneled IV catheter, such as a Hickman, is infection at the insertion site or along the catheter tract. The nurse should instruct the patient to monitor for signs of infection, including redness, swelling, and exudate (pus or drainage) at the insertion site. These signs suggest possible infection, and early detection is critical to preventing more serious complications like sepsis.

C) The primary care provider will monitor hemoglobin and hematocrit values
While monitoring hemoglobin and hematocrit values is important for assessing overall health and blood status, it is not specifically related to monitoring for infection in a client with a tunneled IV catheter. Hemoglobin and hematocrit can provide information about anemia or dehydration but do not directly indicate an infection at the insertion site.

D) To maintain patency, the catheter should be flushed weekly using a 5ml syringe
Although flushing a tunneled IV catheter to maintain patency is important, this response does not directly address infection prevention, which is the focus of the question. Typically, a catheter should be flushed as per specific guidelines (which may include daily or weekly flushing, depending on the clinical setting).

Correct Answer is A

Explanation

A) Use the 3-second markers to count the number of QRS complexes in 6 seconds and multiply by 10:
The 3-second markers on the ECG strip represent a fixed time interval. By counting the number of QRS complexes in the 6-second interval (i.e., two 3-second markers), you can estimate the heart rate by multiplying the number of QRS complexes by 10. This method is quick and effective for calculating heart rate in an emergency setting, such as in arrhythmias or when time is of the essence.

B) Print a 1-minute ECG strip and count the number of QRS complexes:
While this is another way to assess the heart rate, it is not a quick method, especially in emergency situations. It is more time-consuming because it involves printing out a full strip (or ensuring you have enough data to calculate a full minute). This approach may be useful for detailed analysis but is not optimal for quickly estimating the ventricular rhythm.

C) Calculate the number of small squares between one QRS complex and the next one and divide by 1500:
This method is more complex and is used for calculating the heart rate with a more precise ECG reading. It requires counting the number of small squares between two QRS complexes and dividing by 1500 (the number of small squares in one minute). This method is accurate but not the fastest option for quickly estimating the heart rate during an emergency.

D) Count the number of large squares in the R-R interval and divide by 300:
counting the number of large squares between two R-R intervals and dividing by 300, you get the heart rate. However, this method is less commonly used in emergency situations because it requires more time and may not be as immediate as using the 3-second markers. It is more applicable when doing a detailed analysis of the rhythm.

A. IM epinephrine is the fastest route of administration B. IV epinephrine is only administered during cardiac arrest C. Epinephrine would not be administered in this situation D. IM epinephrine is less concentrated than IV.

Correct Answer is B

Explanation

A) IM epinephrine is the fastest route of administration:
While epinephrine is often administered intramuscularly in cases of anaphylaxis and allergic reactions, the speed of action is not the primary reason for choosing this route over intravenous (IV) administration in this situation. Intramuscular administration of epinephrine allows for a rapid onset of action, but it is not necessarily the fastest route compared to IV. IV administration would act more quickly in an emergency setting where immediate blood circulation is critical, but IM is preferred in allergic reactions to prevent excessive systemic effects and to avoid rapid peaks in plasma levels.

B) IV epinephrine is only administered during cardiac arrest:
Epinephrine is generally administered intravenously during life-threatening situations such as cardiac arrest or severe shock, where immediate circulatory effects are needed. In cases of anaphylaxis, however, intramuscular (IM) administration of epinephrine is the preferred route because it allows for a more controlled absorption rate and reduces the risk of excessive blood pressure and other adverse cardiovascular effects. This is the correct rationale for why epinephrine is administered IM in the context of an allergic reaction.

C) Epinephrine would not be administered in this situation:
Epinephrine is the first-line treatment for severe allergic reactions and anaphylaxis, especially in cases where symptoms like wheezing, shortness of breath, urticaria, and itching are present. Therefore, withholding epinephrine is not an appropriate response in this situation. Immediate intervention with epinephrine is critical to reverse the symptoms of anaphylaxis and prevent further respiratory distress or cardiovascular collapse.

D) IM epinephrine is less concentrated than IV:
The concentration of epinephrine used for IM and IV administration is the same. The primary reason for choosing the IM route over the IV route is the slower absorption and the fact that it minimizes the risk of a rapid increase in systemic blood pressure and other adverse reactions. While IM epinephrine may be absorbed more slowly than IV, its concentration is appropriate for treating anaphylaxis effectively. The choice of IM is based on safety and controlled response, not on the concentration of the drug.
