A nurse is preparing to admit a client who has a new diagnosis of methicillin-resistant Staphylococcus aureus (MRSA). The nurse should plan to place the client in which of the following types of transmission-based precautions?

Choice A Reason:

The large intestine does not secrete enzymes to digest food. This function is primarily carried out by the stomach and small intestine. The large intestine’s main role is to absorb water and electrolytes from the remaining indigestible food matter.

Choice B Reason:

This is the correct answer. The large intestine absorbs water from the remaining indigestible food matter, which helps to form stool. This process is crucial for maintaining the body’s fluid balance and for the proper formation and excretion of feces.

Choice C Reason:

Preventing the reflux of food into the esophagus is a function of the lower esophageal sphincter, not the large intestine. The large intestine’s role is more focused on absorbing water and electrolytes and forming stool.

Choice D Reason:

The large intestine does not produce vitamin D. Vitamin D is primarily synthesized in the skin upon exposure to sunlight and can also be obtained from certain foods and supplements. The large intestine does, however, play a role in the absorption of some vitamins produced by gut bacteria, such as vitamin K.

Choice A Reason: Parent who has cardiovascular disease

Having a parent with cardiovascular disease is considered a non-modifiable risk factor. This means it is related to genetic predisposition and cannot be changed or controlled by the individual. While family history is important in assessing stroke risk, it is not something that can be modified through lifestyle changes or medical interventions.

Choice B Reason: Client’s age

Age is another non-modifiable risk factor for stroke. The risk of stroke increases with age, but it is not something that can be altered. While age is an important consideration in stroke risk assessment, it is not a factor that can be modified to reduce the risk.

Choice C Reason: History of sickle cell disease

Sickle cell disease is a genetic disorder that affects the shape and function of red blood cells. It is a non-modifiable risk factor for stroke because it is inherited and cannot be changed. While managing sickle cell disease can help reduce complications, the condition itself remains a fixed risk factor.

Choice D Reason: Hypertension

Hypertension, or high blood pressure, is a significant modifiable risk factor for stroke. It can be managed and controlled through lifestyle changes such as diet, exercise, and medication. Lowering blood pressure can significantly reduce the risk of stroke, making it a key focus in stroke prevention efforts.
