A nurse is reviewing laboratory values of a client who has severe dyspnea. Which of the following laboratory values indicates heart failure?

"I will try to maintain my blood pressure around 116/72." This is because maintaining blood pressure within a normal range can help prevent heart disease. Choice A is incorrect because increasing dairy intake can lead to a higher intake of saturated fats which can increase the risk of heartdisease.

Choice B is incorrect because lowering, not raising, LDL cholesterol is essential in preventing heart disease.

Choice C is incorrect because exercising only twice a week for 25 minutes is not enough to prevent heart disease.

An explanation for why the other choices are not answers: A – Increasing dairy intake can lead to a higher intake of saturated fats which can increase the risk of heart disease, so this is not the correct statement. B – Lowering, not raising, LDL cholesterol is essential in preventing heart disease, so this is not the correct statement. C – Exercising only twice a week for 25 minutes is not enough to prevent heart disease. Thus, this is not the correct statement.

The correct answer is choice B, which cleans a blood spill with chlorine bleach. This is an appropriate action for infection control because bleach is an effective disinfectant that can kill most pathogens, including bloodborne viruses such as HIV and hepatitis B and C.

A. Rolling soiled linen with the clean side in it before placing it in the laundry bag is not the correct answer because it can spread pathogens and cause cross-contamination.

Performing hand hygiene with hands at elbow level is not the correct answer because it is not the correct technique for hand hygiene, which involves washing hands with soap and water or using an alcohol-based hand sanitizer.

Instructing a female client to wipe the perineal area from back to front is not the correct answer because it can cause contamination of the urethra and increase the risk of urinary tract infections.
