A client is being educated about insulin and is able to repeat the newly acquired information using their own words to the nurse.
Which of the following statements confirm the teaching has been effective?

This is because acute pain is the most urgent and life-threatening problem for a client with myocardial infarction.

Acute pain indicates ongoing ischemia and tissue damage, which can lead to complications such as heart failure, arrhythmias, or cardiogenic shock. Therefore, relieving pain is the priority nursing diagnosis.

Choice A. Anxiety is wrong because anxiety is not a specific symptom of myocardial infarction and anxiety is due to the discomfort that happens due to activation of the sympathetic pathway which is good for survival.

Choice C. Knowledge deficit is wrong because knowledge deficit is not an immediate problem for a client with myocardial infarction.

Knowledge deficit can be addressed after the acute phase of the condition is over and the client is stable.

Choice D. Nausea and vomiting are wrong because nausea and vomiting are common symptoms of myocardial infarction, but they are not as urgent and life-threatening as acute pain.

Nausea and vomiting can be treated with antiemetics and fluids, but they do not affect the outcome of the condition as much as pain does.

A 37-year-old who has insulin-dependent diabetes mellitus has the greatest need for special mouth care. This is because diabetes can affect the blood vessels and nerves in the mouth, leading to dry mouth, gum disease, infections, and delayed healing. Special mouth care for this client would include regular brushing and flossing, using a soft toothbrush or foam brush, rinsing with water or saline, checking for signs of inflammation or infection, and avoiding sugary or acidic foods and drinks.

Choice B is wrong because a 58-year-old who wears dentures does not have a greater need for special mouth care than a diabetic client.

Dentures can be removed and cleaned with a soft toothbrush and denture cleaner, and soaked overnight in a denture solution. The gums and mouth should also be cleaned daily with a soft toothbrush or gauze.

Choice C is wrong because a 26-year-old who is on bed rest does not have a greater need for special mouth care than a diabetic client. Bed rest can cause dry mouth and plaque accumulation, but these can be prevented by regular brushing and rinsing, drinking water frequently, and using sugar-free gum or lozenges.

Choice D is wrong because a 45-year-old who is NPO (nothing by mouth) does not have a greater need for special mouth care than a diabetic client. NPO can cause dry mouth and bad breath, but these can be alleviated by regular rinsing with water or saline, applying water-based lip balm or moisturizer, and using artificial saliva products if needed.
