A nurse is teaching a client who has angina about a new prescription for sublingual nitroglycerin tablets.
Which of the following instructions should the nurse include in the teaching?
Take one tablet each morning 30 minutes prior to eating.
Discard any tablets you do not use every 6 months.
Keep the tablets at room temperature in their original glass bottle.
Place the tablet between your cheek and gum to dissolve.
The Correct Answer is C
The correct answer is choice C. Keep the tablets at room temperature in their original glass bottle. Rationales: Choice A rationale: Taking one tablet each morning 30 minutes prior to eating is incorrect. Sublingual nitroglycerin is used to relieve acute angina attacks and is taken as needed rather than on a fixed schedule. Choice B rationale: Discarding any tablets not used every 6 months is incorrect. Sublingual nitroglycerin tablets should be replaced every 6 months to ensure potency, but this is not the main teaching point for safe storage. Choice C rationale: Keeping the tablets at room temperature in their original glass bottle is correct. Nitroglycerin tablets are sensitive to light and moisture, and the original glass bottle protects them from these elements, ensuring their effectiveness. Choice D rationale: Placing the tablet between the cheek and gum to dissolve is incorrect. Sublingual nitroglycerin tablets should be placed under the tongue where they dissolve and are absorbed quickly into the bloodstream for rapid relief of angina symptoms

Correct Answer is B
Explanation
Colesevelam is a bile acid sequestrant that lowers cholesterol by binding to bile acids in the intestine and preventing their reabsorption into the bloodstream. Some possible explanations for the other choices are:
Choice A. Chlorpromazine is wrong because it is an antipsychotic medication that has no effect on cholesterol levels.
Choice C. Colchicine is wrong because it is an anti-inflammatory drug that is used to treat gout and other inflammatory conditions, not high cholesterol.
Choice D. Cimetidine is wrong because it is a histamine H2 receptor antagonist that reduces stomach acid production and is used to treat ulcers and gastroesophageal reflux disease (GERD), not high cholesterol.
Normal ranges for cholesterol levels vary depending on the type of cholesterol and the risk factors of the individual, but generally, total cholesterol should be less than 200 mg/dL, LDL cholesterol should be less than 100 mg/dL, HDL cholesterol should be more than 40 mg/dL for men and 50 mg/dL for women, and triglycerides should be less than 150 mg/dL.
Correct Answer is A
Explanation
Osmotic laxatives work by drawing water into the colon to soften the stool and stimulate bowel movements. However, excessive use of osmotic laxatives can cause fluid volume deficit, which is a state of reduced intravascular volume.
One of the signs of fluid volume deficit is oliguria, which means low urine output.
Choice B. Nausea is wrong because nausea is a common side effect of osmotic laxatives, not an indication of fluid volume deficit.
Choice C. Headaches is wrong because headaches are more likely to be caused by dehydration, which is a state of reduced total body water, mostly affecting the intracellular fluid compartment.
Dehydration can result from osmotic laxatives, but it is not the same as fluid volume deficit.
Choice D. Weight gain is wrong because weight gain is not a sign of fluid volume deficit.
