A nurse receives a unit of packed RBCs from a blood bank and notes that the time is 1130. The nurse should begin the infusion at which of the following times?

When the client states he is ready to start the infusion

As soon as the nurse can prepare the client and the administration set

2 hours after obtaining blood from the blood bank

When the client has finished eating lunch

Answer and Explanation

The Correct Answer is B

A. When the client states he is ready to start the infusion:

While it's important to consider the client's readiness and cooperation, the timing of the infusion should not solely depend on the client's statement. The priority is to start the infusion promptly after receiving the packed red blood cells (PRBCs) from the blood bank to ensure their safety and effectiveness.

B. As soon as the nurse can prepare the client and the administration set:

This choice is the correct answer. After receiving the unit of PRBCs from the blood bank at 1130, the nurse should begin the infusion as soon as possible after preparing the client (ensuring the correct patient, verifying the blood type compatibility, obtaining informed consent, etc.) and the administration set (priming the IV tubing, checking for any leaks, etc.). Prompt administration helps prevent delays that could compromise the quality of the blood product.

C. 2 hours after obtaining blood from the blood bank:

Waiting for 2 hours before starting the infusion is too long and could exceed the recommended timeframe for administering PRBCs after obtaining them from the blood bank. Delaying the infusion for such an extended period could impact the viability and safety of the blood product.

D. When the client has finished eating lunch:

The timing of the client's meal is not a factor in determining when to start the infusion of PRBCs. While it's generally important for the client to have adequate nutrition and hydration, the priority is to administer the blood product promptly after preparation to ensure its efficacy and safety, rather than waiting for unrelated factors such as meal times.

Correct Answer is B

Explanation

A. Initiate a peripheral IV:

Initiating a peripheral intravenous (IV) line may be necessary for clients with unstable angina to facilitate the administration of medications and fluids, especially if there is a need for further interventions or if the client's condition deteriorates. However, in this case, the client's chest pain has improved after receiving nitroglycerin, and there is no immediate indication for IV access based on the information provided.

B. Administer another nitroglycerin tablet:

Nitroglycerin is a vasodilator commonly used to relieve chest pain (angina) by dilating blood vessels and improving blood flow to the heart. The initial response of the client's chest pain severity decreasing from 6 to 2 after one sublingual nitroglycerin tablet indicates a positive response to the medication. However, it's important to assess the client's response further before administering additional doses of nitroglycerin, especially considering the potential for hypotension or other adverse effects.

C. Call the Rapid Response Team:

The Rapid Response Team (RRT) is typically called in situations where there is a concern for a critical event or deterioration of a client's condition that requires immediate intervention. In this scenario, the client's chest pain has improved after nitroglycerin administration, and there are no indications of an acute critical event at this time. Therefore, calling the RRT is not warranted based on the client's current status.

D. Obtain an ECG:

An ECG can be helpful to assess for potential ischemia or other cardiac abnormalities. However, it's not the most urgent action when the client is responding positively to nitroglycerin. It can be done while monitoring the client's response to the second dose.

Correct Answer is ["5"]

Explanation

To calculate how many milliliters (mL) of metoprolol 1 mg/mL solution should be administered to deliver a 5 mg IV bolus dose, you can use the following formula:

Dose (mL) = Desired dose (mg) / Concentration (mg/mL)

In this case:

Desired dose = 5 mg

Concentration = 1 mg/mL

Dose (mL) = 5 mg / 1 mg/mL = 5 mL

Therefore, the nurse should administer 5 mL of metoprolol 1 mg/mL solution per dose to deliver a 5 mg IV bolus for heart rate control.
