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.
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 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.
Correct Answer is A
Explanation
Choice A rationale
Administering supplemental oxygen is the priority intervention for a client with COPD who has an oxygen saturation of 88% on room air. This low oxygen saturation indicates hypoxemia, which requires immediate correction to prevent further respiratory distress.
Choice B rationale
Encouraging the client to use an incentive spirometer is important for lung expansion and preventing atelectasis, but it is not the priority intervention in this scenario. The immediate concern is to correct the hypoxemia.
Choice C rationale
Administering a bronchodilator as prescribed is important for managing COPD symptoms, but the priority intervention is to correct the hypoxemia by administering supplemental oxygen.
Choice D rationale
Positioning the client in high Fowler’s position can help improve breathing, but the priority intervention is to correct the hypoxemia by administering supplemental oxygen.
