A nurse is caring for a client who has sepsis and a prescription for vancomycin 1 g in 250 mL dextrose 5% (D5W) over 2 hr by IV intermitent bolus. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. The radial pulse in the left arm can be palpated after a cardiac catheterization with a left antecubital insertion site. Although the focus is typically on the site of insertion and the brachial pulse, the radial pulse in the left arm can still provide useful information about circulation in that limb.
B. The radial pulse in the right arm is not pertinent because the catheterization was performed on the left side.
C. The brachial pulse in the left arm is indeed important to assess, but palpating the radial pulse in the left arm is also valid to check for circulation.
D. The brachial pulse in the right arm is not relevant in this scenario, as it does not relate to the site of catheterization.

An exercise stress test is a diagnostic procedure that measures the heart's response to physical activity. The client is instructed to walk on a treadmill or pedal a stationary bike while their heart rate, blood pressure, and electrocardiogram are monitored. The test can help detect coronary artery disease, arrhythmias, or other cardiac problems.

The client should follow certain guidelines before the test, such as:

• Avoiding caffeine, nicotine, alcohol, and stimulants for at least 4 hours before the test, as they can affect the heart rate and blood pressure.
• Fasting for at least 2 hours before the test, as eating can affect the blood flow to the heart.
• Getting adequate rest and sleep the night before the test, as fatigue can affect the performance and results of the test.
• Wearing comfortable clothing and shoes that are suitable for exercise.
• Informing the provider of any medications they are taking, as some medications may need to be withheld or adjusted before the test, such as beta blockers, calcium channel blockers, nitrates, or antiarrhythmics. These medications can affect the heart rate and blood pressure and interfere with the interpretation of the test results.

Therefore, the comment made by the client that indicates a need for further teaching is "I'll take my heart medications the morning of my test." The client should consult with their provider about whether they should take their heart medications or not before the test. The other comments made by the client are appropriate and indicate that they understand the pre-test instructions.
