A nurse is providing dietary instructions to a client who has cardiovascular disease. The nurse should identify that which of following statements by the client indicates an understanding of the teaching?

A) Administer nitroglycerin:
Administering nitroglycerin is the priority intervention for acute angina as it helps to quickly relieve chest pain by dilating the coronary arteries and improving blood flow to the heart. This can provide immediate relief from the pain and prevent further myocardial ischemia.

B) Measure blood pressure:
While measuring blood pressure is important to monitor the client's hemodynamic status and assess the effects of the angina and treatments, it is not the first action. Nitroglycerin administration takes precedence to address the acute pain and potential ischemia.

C) Initiate IV access:
IV access is necessary for administering medications and fluids, but it is not the immediate priority in the acute management of angina. Nitroglycerin should be given first to alleviate the symptoms of angina and improve the client's condition.

D) Administer aspirin:
Aspirin is important for its antiplatelet effects to prevent clot formation and reduce the risk of myocardial infarction. However, for immediate relief of acute angina symptoms, nitroglycerin should be administered first. Aspirin can be given soon after to further manage the client's condition.

A. Client report of nausea:
Nausea is a common postoperative symptom that can occur due to anesthesia, pain medications, or other factors. While it is important to manage nausea to ensure the client's comfort and prevent complications like aspiration, it is not as urgent as other potential postoperative complications following a thyroidectomy.

B. Client report of incisional pain:
Incisional pain is expected after surgery and can typically be managed with pain medications. Although it is important to ensure that the client’s pain is adequately controlled, it is not usually indicative of a life-threatening complication and is a normal part of the postoperative healing process.

C. Serosanguineous drainage:
Serosanguineous drainage, a mix of blood and serum, is a typical finding in the early postoperative period and usually indicates normal wound healing. While excessive or unusual drainage should be monitored, small amounts are generally not a cause for immediate concern unless accompanied by signs of infection or other complications.

D. Muscle twitching:
Muscle twitching can indicate hypocalcemia, a potential complication following thyroidectomy due to accidental removal or damage to the parathyroid glands. Hypocalcemia can lead to serious conditions such as tetany or cardiac dysrhythmias. Therefore, muscle twitching is a priority finding that needs immediate reporting and intervention to prevent further complications.
