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
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.

A. Hypocortisolism. B. Hyperinsulinemia. C. Iodide deficiency. D. Azotemia.

Correct Answer is C

Explanation

Choice A rationale
Hypocortisolism, also known as Addison’s disease, is characterized by insufficient production of cortisol by the adrenal glands. It does not typically cause goiter, which is an enlargement of the thyroid gland due to various causes such as iodine deficiency, autoimmune diseases, or nodules.
Choice B rationale
Hyperinsulinemia refers to an excess level of insulin in the blood, often associated with insulin resistance and type 2 diabetes. It is not related to the development of goiter.
Choice C rationale
Iodide deficiency is a common cause of goiter. The thyroid gland requires iodine to produce thyroid hormones. When there is a deficiency, the gland enlarges in an attempt to capture more iodine from the bloodstream.
Choice D rationale
Azotemia is an elevation of blood urea nitrogen (BUN) and serum creatinine levels, typically due to kidney dysfunction. It is not associated with the development of goiter.
