The nurse instructs a client diagnosed with hypertension and coronary artery disease who has been given a new prescription for carvedilol 6.25 mg PO bid to:

Choice A reason: Admission blood pressure is 110/70 is not the information that the nurse must report to the health care provider prior to the procedure. This is a normal blood pressure reading for an adult client and does not indicate any contraindication or complication for the cardiac angiogram.

Choice B reason: Client has multiple food and drug allergies is the information that the nurse must report to the health care provider prior to the procedure. This is a critical information that may affect the choice of contrast agent, medications, or equipment used for the cardiac angiogram. The nurse should identify the specific allergens and the type and severity of the allergic reactions that the client has experienced in the past.

Choice C reason: Pedal pulses are 1+ bilaterally is not the information that the nurse must report to the health care provider prior to the procedure. This is a low-normal finding for the strength of the peripheral pulses and does not indicate any significant vascular impairment or obstruction. The nurse should document and monitor the pedal pulses, but not necessarily report them.

Choice D reason: Client is slightly anxious is not the information that the nurse must report to the health care provider prior to the procedure. This is a common and expected emotional response for a client who is undergoing an invasive diagnostic test and does not require any immediate intervention. The nurse should provide reassurance and education to the client and address any concerns or questions that they may have.

Choice A reason: This is not the best nursing action. Documenting the pulse rate and administering the medications as prescribed may be harmful to the client. Atenolol and diltiazem are both medications that lower the blood pressure and the heart rate. Atenolol is a beta blocker that blocks the effects of adrenaline on the heart and blood vessels. Diltiazem is a calcium channel blocker that relaxes the muscles of the heart and blood vessels. Giving both medications to a client who already has a low and irregular heart rate may cause further bradycardia, which is a heart rate below 60 beats/minute, or arrhythmia, which is an abnormal heart rhythm. The nurse should check the parameters and the contraindications for the medications before administering them.

Choice B reason: This is not the best nursing action. Assessing for chest pain and administering atenolol if pain free may not be appropriate for the client. Chest pain can be a sign of angina or myocardial infarction, which are conditions where the blood flow to the heart is reduced or blocked. Atenolol can help relieve chest pain by reducing the oxygen demand of the heart, but it can also lower the heart rate and the blood pressure. The client already has a low and irregular heart rate, which may indicate a problem with the electrical conduction of the heart. The nurse should not give atenolol without checking the pulse rate and the blood pressure, and consulting the health care provider.

Choice C reason: This is the best nursing action. Holding the atenolol and administering the diltiazem is the most appropriate for the client. Atenolol can lower the heart rate and the blood pressure, which may worsen the client's condition. The nurse should hold the atenolol and notify the health care provider of the client's pulse rate and rhythm. Diltiazem can also lower the heart rate and the blood pressure, but it can also help regulate the heart rhythm by slowing down the electrical impulses in the heart. The nurse should administer the diltiazem as prescribed, and monitor the client's vital signs and cardiac status.

Choice D reason: This is not the best nursing action. Withholding the medications and reassessing the heart rate in 30 minutes may delay the treatment and the care of the client. The client has a low and irregular heart rate, which may indicate a serious cardiac problem that needs immediate attention. The nurse should not wait for 30 minutes to reassess the heart rate, but rather act promptly and notify the health care provider. The nurse should also administer the diltiazem as prescribed, unless there is a specific reason to withhold it.
