A client has a triple lumen subclavian central venous catheter (CVC) with D51/2NS infusing through one lumen (port) at 75 mL per hour. The nurse has an order to transfuse one unit of packed red blood cells (PRBCs). The nurse's safest action is to:

contact the prescriber to decrease the rate of the D51/2 NS during the blood transfusion

stop the D51/2NS, check the client's vitals & notify the prescriber.

Fluids cannot be given through a CVC.

Insert a 22 gauge peripheral IV to administer the transfusion

transfuse the unit of packed red blood cells through a separate lumen of the CVC

Answer and Explanation

The Correct Answer is E

A. contact the prescriber to decrease the rate of the D51/2NS during the blood transfusion: There's no need to alter the rate of maintenance fluids unless there's a fluid volume concern. Additionally, decreasing the rate would not address the need for a dedicated blood transfusion line if another lumen is available.

B. stop the D51/2NS, check the client's vitals & notify the prescriber: Stopping necessary fluids without cause may compromise fluid balance. Unless there's a compatibility issue or no other lumen, stopping the infusion is not the safest or most efficient action.

C. Fluids cannot be given through a CVC: Central venous catheters are routinely used for administering fluids, medications, and blood products, especially in critical care settings.

D. Insert a 22 gauge peripheral IV to administer the transfusion: While blood can be given through a peripheral IV, using an existing central venous catheter is safer and more efficient, especially when multiple lumens are available. Inserting a new IV unnecessarily increases infection and complication risks.

E. transfuse the unit of packed red blood cells through a separate lumen of the CVC: This is the safest and most appropriate action. Triple-lumen CVCs allow for simultaneous infusions through separate channels without mixing. Blood should be transfused through a dedicated lumen to avoid incompatibility or dilution by other fluids.

Correct Answer is C

Explanation

A. Administer an antidiarrheal medication: Atropine is an anticholinergic agent that reduces gastrointestinal motility, often leading to constipation rather than diarrhea. Administering an antidiarrheal would not be appropriate and could cause harmful effects if unnecessary.

B. Assess the pupils for constriction: Atropine causes pupil dilation (mydriasis), not constriction. Checking for constriction would not align with the expected pharmacologic effects of the drug and is not a priority assessment after administration.

C. Provide frequent oral care: Atropine inhibits secretions as part of its anticholinergic effects, often leading to dry mouth (xerostomia). Frequent oral care helps maintain mucous membrane integrity and client comfort, making this an appropriate nursing action following administration.

D. Insert an indwelling catheter: Although atropine can cause urinary retention, especially in older adults, catheter insertion is not routinely required after administration; a single 0.5 mg IV dose is less likely to cause significant urinary retention requiring catheterization. It should only be considered if the client shows clinical signs of acute urinary retention.

A. Have blood drawn weekly to check for high magnesium levels B. Avoid the use of salt substitutes in your diet C. Notify your physician if a headache develops D. Take your heart rate daily when on this medication

Correct Answer is B

Explanation

A. Have blood drawn weekly to check for high magnesium levels: Lisinopril, an ACE inhibitor, does not significantly affect magnesium levels. Regular monitoring is more important for potassium and renal function (BUN/creatinine), especially in heart failure patients, not magnesium.

B. Avoid the use of salt substitutes in your diet: Lisinopril is an ACE inhibitor. ACE inhibitors can cause potassium retention by reducing the production of aldosterone. Many salt substitutes contain high amounts of potassium chloride and combining the two may lead to hyperkalemia. Patients should be instructed to avoid these substitutes unless approved by their provider.

C. Notify your physician if a headache develops: Headache is a relatively common and usually mild side effect of lisinopril. It does not typically warrant discontinuation or immediate provider notification unless it's severe or persistent with other symptoms like dizziness or visual changes.

D. Take your heart rate daily when on this medication: Lisinopril does not significantly affect heart rate. Monitoring blood pressure is more relevant, as ACE inhibitors are antihypertensives. Heart rate monitoring is more critical with beta blockers or calcium channel blockers.
