A nurse is collecting data from a client who states she recently started taking garlic as an herbal supplement. The nurse should advise the client to stop taking garlic due to a potential reaction with which of the following client medications?

A. Furosemide can decrease the renal clearance of lithium, leading to increased lithium levels in the blood. This can potentiate the toxic effects of lithium, such as neurotoxicity and cardiac toxicity. Therefore, concurrent use of furosemide and lithium is generally contraindicated, and caution is advised. The nurse should identify lithium carbonate as contraindicated in this scenario.
B. Albuterol is a bronchodilator commonly used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). There are no significant contraindications between albuterol and furosemide.
C. Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. There are no significant contraindications between levothyroxine and furosemide.
D. Cetirizine is an antihistamine used to treat allergies and allergic reactions. There are no significant contraindications between cetirizine and furosemide. They are generally considered safe to use together.

B. Headache, particularly a pounding headache or throbbing sensation, is a well-known side effect of nitroglycerin use. It occurs due to the vasodilatory effects of nitroglycerin, which can lead to dilation of blood vessels in the head and neck.
A. Ringing in the ears, also known as tinnitus, is not a common adverse effect of nitroglycerin. Tinnitus is typically associated with certain medications, exposure to loud noises, or underlying medical conditions such as inner ear disorders. It is not a recognized adverse effect of nitroglycerin.
C. Nitroglycerin is not known to increase blood pressure. In fact, it typically causes vasodilation and can lead to a decrease in blood pressure, especially when used sublingually or transdermally. Hypotension, rather than hypertension, is a potential adverse effect of nitroglycerin therapy.

D. Polyuria, or excessive urination, is not a recognized adverse effect of nitroglycerin. Polyuria may occur as a result of other medications or underlying medical conditions affecting renal function, but it is not directly associated with nitroglycerin use.
