Which infection control measure, by the nurse, reduces the potential spread of methicillin-resistant Staphylococcus aureus (MRSA)?

A.

Wearing an N95 mask while in the room of a patient with airborne precautions.

B.

Wearing a facemask while in the room of a patient with droplet precautions.

C.

Use of a separate disposable blood pressure cuff for any patient with a draining wound.

D.

Use of strict hand washing measures once in every 8-hour work shift.

Answer and Explanation

The Correct Answer is C

Choice A rationale

 

Wearing an N95 mask is appropriate for airborne precautions, such as tuberculosis, but not specifically for MRSA, which requires contact precautions.

 

Choice B rationale

 

Wearing a facemask is suitable for droplet precautions, such as influenza, but MRSA is primarily spread through direct contact, not droplets.

 

Choice C rationale

 

Using a separate disposable blood pressure cuff for patients with draining wounds helps prevent the spread of MRSA. MRSA can be transmitted via contaminated medical equipment.

 

Choice D rationale

 

Strict hand washing measures are essential but should be performed more frequently than once every 8-hour shift. Hand hygiene should be practiced before and after patient contact.

Correct Answer is B

Explanation

Choice A rationale

Checking blood sugar levels before each meal is a good practice for managing diabetes and does not indicate a need for further teaching.

Choice B rationale

Skipping medication if blood sugar is normal indicates a misunderstanding of diabetes management. Medications should be taken as prescribed to maintain consistent blood sugar levels.

Choice C rationale

Following a balanced diet and exercising regularly are important components of diabetes management and do not indicate a need for further teaching.

Choice D rationale

Monitoring feet for cuts or sores is crucial for diabetes management to prevent complications like infections and ulcers.

Correct Answer is A

Explanation

Choice A rationale

Hypersplenism is a condition often associated with cirrhosis, where the spleen becomes overactive. This leads to the destruction of blood cells, causing anemia (low red blood cells), leukopenia (low white blood cells), and thrombocytopenia (low platelets).

Choice B rationale

Peptic ulcer disease primarily affects the stomach and duodenum, leading to ulcers and bleeding. It does not typically cause anemia, leukopenia, and thrombocytopenia in the context of cirrhosis.

Choice C rationale

Cholecystitis is the inflammation of the gallbladder, usually due to gallstones. It does not cause the blood cell abnormalities seen in cirrhosis.

Choice D rationale

Esophageal varices are swollen veins in the esophagus that develop due to portal hypertension in cirrhosis. While they can cause bleeding, they do not directly cause anemia, leukopenia, and thrombocytopenia.
