A nurse is reinforcing teaching with a group of adolescent male clients about testicular examinations. Which of the following statements by a client indicates an understanding of the teaching?

A. "Count the client's respirations for 15 seconds" is incorrect. The nurse should count respirations for a full 60 seconds to ensure accuracy, especially in postoperative clients, as irregularities may be more easily detected with a longer observation period.

B. "Place the client in a supine position" is not necessary. While the position of the client can affect respiration, the nurse does not need to place the client in a supine position specifically to assess respirations. The client should be in a comfortable position that allows for adequate observation.

C. "Inform the client when beginning to observe his respirations" is incorrect. The client should not be aware that their respirations are being counted, as awareness can alter their breathing patterns and lead to inaccurate data.

D. "Observe the movements of the client's chest wall" is correct. Observing the chest wall allows the nurse to assess the rate, depth, and rhythm of respirations, as well as any signs of distress or abnormal patterns, which is crucial for monitoring postoperative respiratory status.

A. Thrombocytopenia: Neither atenolol nor nitroglycerin is commonly associated with thrombocytopenia. This is not the primary concern when these two medications are used together.

B. Dry cough: A dry cough is a known side effect of ACE inhibitors (e.g., enalapril), but it is not commonly associated with atenolol or nitroglycerin.

C. Hypotension: Both atenolol (a beta-blocker) and nitroglycerin (a vasodilator) can lower blood pressure. When taken together, there is an increased risk of hypotension, especially when standing up quickly. The nurse should monitor the client for symptoms of low blood pressure such as dizziness, fainting, or lightheadedness.

D. Hyperglycemia: Atenolol may mask signs of hypoglycemia in clients with diabetes, but it does not directly cause hyperglycemia. Nitroglycerin is not typically associated with hyperglycemia either. Therefore, hyperglycemia is not a concern in this scenario.
