A nurse is caring for a client who is scheduled for an exercise stress test. Which of the following comments made by the client should indicate to the nurse that the client requires further teaching?

"I'll skip my coﬀee the morning of my test."

"I'll take my heart medications the morning of my test."

"I'll get 8 hours of sleep the night before the test."

"I will not smoke prior to my test."

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is B

Explanation

The priority nursing action is to notify the provider of the client's allergy because shellfish allergy may indicate an allergy to iodine, which is commonly used as a contrast dye in cardiac catheterization. This could cause a severe allergic reaction or anaphylaxis during the procedure, which could be life-threatening. The provider may need to order a diﬀerent type of contrast dye or premedicate the client with antihistamines or steroids to prevent an allergic reaction.

a. Ask the client if any other foods cause such a reaction is wrong because it is not the priority action and it does not address the potential risk of iodine allergy.

c. Notify the dietary department of the client's allergy is wrong because it is not relevant to the cardiac catheterization and it does not prevent an allergic reaction during the procedure.

d. Atach a wrist band indicating the client's allergy is wrong because it is not sufficient to alert the provider or the catheterization team of the client's allergy and it does not prevent an allergic reaction during the procedure.

Correct Answer is ["8 mL"]

Explanation

To calculate the volume to administer, the nurse should use the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL) x 1000

Plugging in the given values, the nurse should get:

Volume (mL) = 400 mg / 250 mg/5 mL x 1000

Volume (mL) = 8 mL

The nurse should round the answer to the nearest whole number and use a leading zero if it applies. Therefore, the nurse should administer 8 mL of valproic acid per dose.
