A post-op client is to receive the following: D5%W/0.45% NS 1 L to infuse over 5 hours. What is the appropriate setting on an infusion pump in milliliters per hour? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["200"]

Volume ordered is 1 L.

Convert the total volume to milliliters (mL)

1 L = 1000 mL.

Total volume in mL = 1 L × 1000 mL/L = 1000 mL

Total infusion time = 5 hours

Calculate the infusion rate in milliliters per hour (mL/hr).

Infusion rate (mL/hr) = Total volume (mL) / Total infusion time (hours)

= 1000 mL / 5 hours

= 200

The appropriate setting is 200 mL/hr.

Correct Answer is A

Explanation

A. Review daily the necessity of the central venous catheter: One of the most effective strategies to reduce the risk of catheter-related bloodstream infections is to remove the central line as soon as it is no longer needed. Daily evaluation of necessity prevents prolonged catheter use, which significantly increases infection risk. Removing the source of potential infection is the ultimate preventative action.

B. Maintain a pressure of 300 mm Hg on the flush bag: While maintaining appropriate flush pressure is important for catheter patency and preventing blood clots, it does not play a direct role in preventing bloodstream infections. This action is more related to ensuring adequate line function rather than infection control.

C. Cleanse the insertion site daily with isopropyl alcohol: Current guidelines recommend using chlorhexidine-based solutions rather than isopropyl alcohol for skin antisepsis due to better antimicrobial efficacy. Daily site care is important, but the choice of antiseptic is critical in reducing infection risk.

D. Change the pressurized tubing system and flush bag daily: Tubing and flush systems should be changed typically every 72–96 hours unless contamination is suspected. Changing them daily is not recommended and does not provide added protection against infection it may even increase risk with unnecessary manipulation.

A. Diaphoresis, hypertension B. Palpitations, shortness of breath C. Systolic murmur, severe anxiety D. Visual changes, anorexia

Correct Answer is B

Explanation

A. Diaphoresis, hypertension: While diaphoresis may occur in response to the discomfort or anxiety caused by a rapid heart rate, hypertension is not a typical feature of atrial flutter. The rapid ventricular response can more often lead to hypotension if cardiac output is compromised.

B. Palpitations, shortness of breath: These are hallmark symptoms of rapid atrial flutter. Palpitations result from the fast, irregular atrial contractions, while shortness of breath may occur due to decreased cardiac output and poor ventricular filling during rapid rates.

C. Systolic murmur, severe anxiety: Atrial flutter is not typically associated with a systolic murmur unless there is a pre-existing valvular condition. Anxiety may be present but is a nonspecific response and not as directly linked to atrial flutter as palpitations and dyspnea.

D. Visual changes, anorexia: These symptoms are not characteristic of atrial flutter. Visual changes may occur with severe hypotension or embolic events, and anorexia may be seen in chronic illness, but neither is directly tied to the acute presentation of atrial flutter.
