A nurse is reinforcing health promotion education at a community health fair. Which of the following statements by attendees indicates understanding of the teaching?

Choice A reason: Doing testicular self-exam every 6 months without fail is not an adequate frequency, as it can delay the detection of any changes or abnormalities in the testes that may indicate cancer or other conditions. Men should perform testicular self-exam monthly, preferably after a warm bath or shower.

Choice B reason: The flu shot received last year will not last for 2 years, as it only provides protection against specific strains of influenza virus that may change from year to year. People should get a flu shot annually, preferably before the flu season starts.

Choice C reason: Examining breasts a week after each menstrual period is an optimal time, as breasts are less likely to be swollen, tender, or lumpy due to hormonal fluctuations. Women should perform breast self-exam monthly, preferably at the same time each month.

Choice D reason: Getting a hepatitis B vaccine on a yearly basis is not necessary, as it only requires three doses at 0, 1, and 6 months to provide lifelong immunity against hepatitis B virus infection. People who are at high risk of exposure to hepatitis B virus should get tested for antibodies before receiving the vaccine series.

Choice A: This is incorrect because taking iron supplement with an antacid can reduce its absorption and effectiveness. The client should take iron supplement on an empty stomach or with a source of vitamin C to enhance its absorption.

Choice B: This is incorrect because drinking liquid iron supplement undiluted can stain the teeth and cause irritation to the mouth and throat. The client should dilute liquid iron supplement with water or juice and drink it through a straw.

Choice C: This is correct because increasing fiber intake while taking iron supplement can help prevent constipation, which is a common side effect of iron supplementation. The client should also drink plenty of fluids and exercise regularly to promote bowel movements.

Choice D: This is incorrect because notifying the doctor if stools turn black is not necessary as it is a normal and harmless effect of iron supplementation. The client should only notify the doctor if stools are tarry, bloody, or have a foul odor, which can indicate gastrointestinal bleeding.
