A nurse is caring for a client who has cirrhosis of the liver and is receiving spironolactone. Which of the following findings indicates that the client is responding to the treatment?

A) "Call 911 if pain persists 30 minutes after taking one tablet": This instruction is not accurate and could potentially delay appropriate medical intervention for angina. Nitroglycerin sublingual tablets are rapid-acting vasodilators used to relieve acute angina symptoms. If chest pain persists after taking one tablet, the client should take another tablet after 5 minutes. If the pain persists after a total of three tablets, the client should seek emergency medical assistance.

B) "Place the tablet under the tongue until dissolved": This instruction is correct. Nitroglycerin sublingual tablets should be placed under the tongue and allowed to dissolve completely. Sublingual administration allows for rapid absorption of the medication into the bloodstream, providing quick relief of angina symptoms.

C) "Store the tablets in a refrigerator in a plastic container": This instruction is incorrect. Nitroglycerin sublingual tablets should be stored in their original container at room temperature, away from moisture and heat. Storing them in the refrigerator could alter their effectiveness.

D) "Take a tablet every 10 minutes until the pain subsides": This instruction is incorrect and potentially dangerous. Nitroglycerin sublingual tablets should be taken as directed by the healthcare provider or based on the client's angina management plan. Typically, the client should take one tablet at the onset of angina symptoms and repeat the dose every 5 minutes if the pain persists, up to a maximum of three tablets within 15 minutes. Taking a tablet every 10 minutes without regard to symptom relief or maximum dosage limits could lead to hypotension and other adverse effects.

A) Pain level: Assessing the client's pain level may be important for administering analgesic medications, but it is not directly related to the administration of propranolol. Propranolol is a beta-blocker primarily used to treat conditions such as hypertension, angina, and certain cardiac arrhythmias, so assessing pain level is not the priority.

B) Respiratory rate: While monitoring respiratory rate is important in various clinical situations, propranolol administration does not typically have a direct effect on respiratory function. Therefore, assessing the respiratory rate specifically before administering propranolol may not be as relevant as other vital signs.

C) Heart rate: Propranolol is a beta-blocker that primarily works by slowing the heart rate and reducing the workload on the heart. Therefore, it is crucial for the nurse to assess the client's heart rate prior to administering propranolol to ensure it is within the appropriate range. Administering propranolol to a client with bradycardia or a significantly low heart rate could exacerbate this condition and lead to adverse effects.

D) Temperature: While monitoring temperature is important for assessing for signs of infection or other systemic issues, it is not directly relevant to the administration of propranolol. Propranolol primarily affects cardiovascular function, so assessing temperature is not typically a priority before administering this medication
