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

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

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

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

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 A

Explanation

Choice A rationale
It takes about 14 days to develop antibodies and immunity to the disease after vaccine administration. This is why the patient is asked to return in 2 to 3 weeks for an antibody titer. The immune system needs time to respond to the vaccine and produce detectable levels of antibodies.
Choice B rationale
The laboratory running out of blood specimen tubes is not a valid reason for delaying the antibody titer. This choice does not provide an accurate explanation for the patient.
Choice C rationale
It takes about 14 days to develop antibodies, not antigens, and immunity to the disease after vaccine administration. This choice contains incorrect information about the immune response.
Choice D rationale
After receiving the vaccine, the patient is not likely to transmit the communicable disease to the laboratory. This choice does not provide a valid reason for delaying the antibody titer.

A. Post-renal acute kidney injury (AKI). B. Diabetes insipidus (DI). C. Syndrome of inappropriate antidiuretic hormone (SIADH). D. Congestive heart failure (CHF).

Correct Answer is D

Explanation

Choice A rationale
Post-renal acute kidney injury (AKI) is caused by obstruction of urine flow, leading to decreased urine output, but it does not typically cause crackles in the lungs.
Choice B rationale
Diabetes insipidus (DI) is characterized by excessive urination and thirst due to a deficiency of antidiuretic hormone (ADH), but it does not cause crackles in the lungs.
Choice C rationale
Syndrome of inappropriate antidiuretic hormone (SIADH) involves excessive release of ADH, leading to water retention and hyponatremia, but it does not cause crackles in the lungs.
Choice D rationale
Congestive heart failure (CHF) can lead to fluid accumulation in the lungs (crackles) and decreased urine output due to poor cardiac function and renal perfusion.
