A client is scheduled to receive atenolol 25 mg PO and diltiazem 60 mg PO at 0800. The nurse assesses the client's heart rate as 45 beats/minute and irregular. What is the best nursing action at this time?

Choice A reason: This is not a correct answer. A decrease in urination is not a common side effect of amlodipine. Amlodipine is a calcium channel blocker that lowers the blood pressure and relaxes the blood vessels. Amlodipine does not affect the kidney function or the urine output, unless there is an underlying renal problem or a drug interaction. The client should monitor their urination, but not expect a decrease.

Choice B reason: This is the correct answer. An increase in lower extremity edema is a common side effect of amlodipine. Amlodipine can cause fluid retention and swelling in the legs, ankles, or feet. This is due to the dilation of the blood vessels and the leakage of fluid into the tissues. The client should monitor their weight and the size of their lower extremities, and report any significant changes to their health care provider. The client may also elevate their legs, wear compression stockings, or take diuretics to reduce the edema.

Choice C reason: This is not a correct answer. Tachycardia during exercise is not a common side effect of amlodipine. Amlodipine can lower the heart rate and the cardiac output, which can reduce the oxygen demand of the heart. Amlodipine does not cause an increase in the heart rate, unless there is an underlying cardiac problem or a drug interaction. The client should monitor their pulse and blood pressure, but not expect tachycardia.

Choice D reason: This is not a correct answer. An increase in bowel motility is not a common side effect of amlodipine. Amlodipine does not affect the gastrointestinal system or the digestion, unless there is an allergic reaction or a drug interaction. Amlodipine can cause some gastrointestinal side effects, such as nausea, abdominal pain, or constipation, but not an increase in bowel motility. The client should monitor their bowel movements, but not expect an increase.

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.
