The nurse is providing education to a client who experiences recurrent levels of moderate anxiety to situations and perceived stress. In addition to information about prescribed medication and administration, which instruction should the nurse include in the teaching?

Choice A: Conversion of the client's PPD test from negative to positive is not the most important information for the nurse to note, as this is an expected finding for a client who has been exposed to tuberculosis and does not affect the administration of isoniazid. This is a distractor choice.

Choice B: History of intravenous drug abuse is not the most important information for the nurse to note, as this is not directly related to the use of isoniazid and does not contraindicate its administration. This is another distractor choice.

Choice C: Current diagnosis of hepatitis B is the most important information for the nurse to note, as this can increase the risk of hepatotoxicity and liver damage from isoniazid, which requires close monitoring and possible dose adjustment. Therefore, this is the correct choice.

Choice D: Length of time of the exposure to tuberculosis is not the most important information for the nurse to note, as this does not influence the dosage or frequency of isoniazid and does not indicate any complication or adverse reaction. This is another distractor choice.

Choice B is correct because sodium intake can be regulated by limiting canned foods in the diet. Canned foods often contain high amounts of sodium as a preservative, which can increase blood pressure and fluid retention. The nurse should advise the client to choose fresh or frozen foods instead of canned foods or rinse them before eating.

Choice C is correct because salt substitutes can help with maintaining a healthy diet by reducing sodium intake. Salt substitutes are products that contain potassium chloride or other ingredients that mimic the taste of salt but have less or no sodium. The nurse should advise the client to use salt substitutes sparingly and check with their healthcare provider before using them if they have kidney problems or take certain medications.

Choice D is correct because weight management is promoted by taking daily walks for thirty minutes. Being overweight or obese can increase blood pressure and strain the heart and blood vessels. The nurse should advise the client to lose weight or maintain a healthy weight by engaging in regular physical activity and eating a balanced diet.

Choice F is correct because uncontrolled hypertension can lead to renal damage. High blood pressure can damage the blood vessels in the kidneys and impair their function, leading to chronic kidney disease or failure. The nurse should advise the client to monitor their blood pressure regularly and take prescribed medications as directed.

Choice A is incorrect because alcohol consumption can produce vascular changes that increase blood pressure. Alcohol can cause vasodilation, which lowers blood pressure temporarily, but also stimulates the sympathetic nervous system, which raises blood pressure over time. The nurse should advise the client to limit alcohol intake to no more than one drink per day for women and two drinks per day for men.

Choice E is incorrect because blood pressure readings should not be taken at noontime. Blood pressure readings should be taken at the same time each day, preferably in the morning before breakfast or in the evening before dinner, when blood pressure is usually lower and more stable. The nurse should advise the client to avoid taking blood pressure readings when they are stressed, anxious, or have just exercised or eaten.
