The nurse is reviewing the laboratory data of a client diagnosed with coronary artery disease. Which set of laboratory results indicates a need for client teaching regarding dietary modifications?

Choice A reason: Avoiding strenuous activity and standing up slowly is not a relevant response to the client's complaint of headache. These actions may help prevent or reduce orthostatic hypotension, which is another possible side effect of nitroglycerin, but not headache.

Choice B reason: Headache is expected and should subside with continued use is a correct and appropriate response to the client's complaint of headache. The nurse should explain that headache is a common and transient side effect of nitroglycerin, which is caused by the vasodilation effect of the drug. The nurse should also advise the client to take over-the-counter analgesics, such as acetaminophen, to relieve the headache.

Choice C reason: Reducing the dosage to help relieve this side effect is not a correct or appropriate response to the client's complaint of headache. The nurse should not suggest any changes in the prescribed dosage of nitroglycerin, as this may compromise the effectiveness of the drug and increase the risk of angina or myocardial infarction. The nurse should also remind the client to follow the instructions for applying and removing the Nitropatch.

Choice D reason: You will have this side effect as long as you are taking nitroglycerin is not a correct or appropriate response to the client's complaint of headache. The nurse should not discourage or alarm the client by implying that the headache is inevitable and permanent. The nurse should reassure the client that the headache will likely diminish over time as the body adapts to the drug.

Choice A reason: Withholding the dose and reassessing the blood pressure in 30 minutes is not the most appropriate action at this time. Furosemide is a drug that reduces fluid retention and swelling by increasing the urine output. ¹ The client has pulmonary congestion, which means that there is excess fluid in the lungs, causing difficulty breathing and low oxygen levels. ² Delaying the administration of furosemide may worsen the client's condition and increase the risk of complications, such as pulmonary edema or heart failure.

Choice B reason: Calling the healthcare provider to obtain an order for oral furosemide is not the most appropriate action at this time. Oral furosemide is a tablet that is swallowed and absorbed by the digestive system. ¹ It takes longer to act than intravenous (IV) furosemide, which is injected directly into the bloodstream. ¹ The client has pulmonary congestion, which requires immediate treatment to relieve the fluid accumulation in the lungs. Switching to oral furosemide may delay the therapeutic effect and compromise the client's outcome.

Choice C reason: Administering the medication and notifying the healthcare provider of the blood pressure is the most appropriate action at this time. Furosemide is a drug that reduces fluid retention and swelling by increasing the urine output. ¹ The client has pulmonary congestion, which means that there is excess fluid in the lungs, causing difficulty breathing and low oxygen levels. ² Administering IV furosemide can help remove the excess fluid from the lungs and improve the client's breathing and oxygenation. However, furosemide can also lower the blood pressure by reducing the volume of fluid in the blood vessels. ¹ The client already has low blood pressure, which can cause dizziness, fainting, or shock. The nurse should notify the healthcare provider of the blood pressure and monitor the client for any signs of hypotension or adverse reactions.

Choice D reason: Administering the dose and continuing to monitor the vital signs is not the most appropriate action at this time. Furosemide is a drug that reduces fluid retention and swelling by increasing the urine output. ¹ The client has pulmonary congestion, which means that there is excess fluid in the lungs, causing difficulty breathing and low oxygen levels. ² Administering IV furosemide can help remove the excess fluid from the lungs and improve the client's breathing and oxygenation. However, furosemide can also lower the blood pressure by reducing the volume of fluid in the blood vessels. ¹ The client already has low blood pressure, which can cause dizziness, fainting, or shock. The nurse should not only monitor the vital signs, but also notify the healthcare provider of the blood pressure and report any changes or concerns.
