To prevent urinary tract infection, the nurse must teach the patient the following.

Select all that apply.

These are all measures that can help prevent urinary tract infection (UTI), which is an infection in any part of the urinary system, including kidneys, ureters, bladder, and urethra.

Choice A is wrong because holding the urge to urinate as much as possible can allow bacteria to grow in the bladder and cause infection.It is better to urinate frequently and completely to flush out any germs that may enter the urinary tract.

Choice B is correct because emptying the bladder before and after sexual intercourse can help remove any bacteria that may have been introduced during sex.Sexual activity is one of the common causes of UTI, especially in women.

Choice C is correct because taking antibiotics as ordered can help treat an existing UTI or prevent a recurrent one.Antibiotics are the first line of treatment for UTI and they work by killing the bacteria that cause the infection.

Choice D is correct because female patients should wipe from front to back after using the bathroom.This can prevent bacteria from the anus or fecal matter from spreading to the urethra and causing infection.

Choice E is correct because drinking 8 to 10 glasses of water a day can help dilute the urine and flush out any bacteria that may be present in the urinary tract.Water also helps maintain a healthy urinary system by keeping it hydrated and functioning well.

This is because nitroglycerin patches can cause tolerance if they are used continuously, which reduces their effectiveness in preventing angina attacks. Removing the patch each evening allows the body to restore its sensitivity to the drug.

Choice A is wrong because nitroglycerin patches should be applied every 24 hours, not every 48 hours.

Applying a new patch every 48 hours would result in inadequate blood levels of the drug and increased risk of angina.

Choice B is wrong because nitroglycerin patches should not be cut in half or altered in any way.

Cutting the patch would compromise the integrity of the drug delivery system and could lead to unpredictable or excessive doses of the drug.

Choice C is wrong because nitroglycerin patches should not be taken off for 30 minutes if a headache occurs.

Headache is a common side effect of nitroglycerin due to its vasodilating action, but it usually subsides with continued use.

Taking off the patch for 30 minutes could increase the risk of angina by interrupting the steady blood levels of the drug.

The nurse should advise the client to take an analgesic such as acetaminophen for headache relief.
