A nurse is consulting a pharmacological reference about medication compatibility prior to administering warfarin to a client.
Which of the following medications should the nurse identify as being incompatible with warfarin?

The correct answer isChoice D, remove the protective gown while in the client’s room.

Choice A rationale: Wearing a face shield is not specifically required for Clostridium difficile infection (CDI) precautions. CDI is primarily spread through the fecal-oral route, and while a face shield could provide protection against splashes during procedures that might generate them, it is not a standard precaution for entering the room of a patient with CDI.

Choice B rationale: Placing a mask on the client during transport is not a standard precaution for CDI. While it is important to prevent the spread of infection, CDI is not transmitted through the respiratory route, so a mask for the client would not be necessary in this context.

Choice C rationale: Using an alcohol-based hand rub is generally recommended for hand hygiene. However, for CDI, alcohol-based hand rubs are not effective against C. difficile spores. The Centers for Disease Control and Prevention (CDC) recommends washing hands with soap and water after caring for patients with CDI to physically remove the spores from the hands.

Choice D rationale: Removing the protective gown while still in the client’s room is the correct action to prevent the spread of contamination. Gowns should be removed before leaving the patient’s room to avoid dispersing contaminants to other areas of the healthcare facility.

Infection control for CDI involves several specific actions due to the resilience of C. difficile spores. These spores can survive on surfaces for a long time and are resistant to many common disinfectants, which is why environmental cleaning and disinfection with agents effective against C. difficile, such as bleach-based products, are crucial. Additionally, healthcare workers should use gloves and gowns when entering the rooms of patients with CDI and should ensure that these are disposed of correctly after use.

The correct answer is choice C: Initiate continuous cardiac monitoring.

Choice A rationale:

Implementing fluid restrictions is not recommended for a child with diabetic ketoacidosis (DKA). DKA is characterized by severe dehydration due to osmotic diuresis, and fluid replacement is a critical component of treatment to restore hydration and circulatory volume.

Choice B rationale:

Monitoring vital signs every 8 hours is not sufficient for a child with DKA. DKA is an acute, life-threatening condition that requires close monitoring of vital signs to detect changes in the patient’s condition promptly. Vital signs should be monitored more frequently, typically every 1 to 2 hours, depending on the severity of the DKA and institutional protocols.

Choice C rationale:

Continuous cardiac monitoring is recommended for a child with DKA. DKA can lead to serious electrolyte imbalances, such as hypokalemia, which can cause cardiac arrhythmias. Continuous cardiac monitoring allows for the early detection and treatment of these potential complications.

Choice D rationale:

Administering subcutaneous insulin 30 minutes before meals is not appropriate for the acute management of DKA. In DKA, insulin is typically administered intravenously to rapidly decrease blood glucose levels and correct metabolic acidosis. Subcutaneous insulin is not used until the patient is stable and able to eat.
