Correct Answer: B

Rationale: Using a sterile technique throughout the procedure is essential to prevent infection when inserting an IV catheter. This includes maintaining aseptic conditions, using sterile equipment, and following proper hand hygiene practices. Choice A is incorrect because threading the catheter up to the hub does not specifically address infection prevention. Choice C is incorrect as cleaning the insertion site with alcohol only may not provide adequate disinfection, as it is essential to use an antiseptic solution to reduce microbial load. Choice D is incorrect as wearing gloves alone is not sufficient protection against infection; a mask should also be worn to prevent the spread of microorganisms through respiratory secretions.

Correct Answer: A

Rationale: Practice sessions are an effective psychomotor approach to learning for adolescents with ostomies as they involve hands-on practice of ostomy care skills, which can help reinforce learning through active engagement. Demonstrations (choice B) can be helpful in providing visual guidance but may not offer the same level of active participation and practice as practice sessions. Written instructions (choice C) may be useful for reference but may not be as effective in developing psychomotor skills. Group discussions (choice D) focus more on verbal exchange and may not directly address the need for hands-on skill development required in managing ostomies. Therefore, practice sessions are the most suitable method for enhancing psychomotor learning in this scenario.

Correct Answer: A

Rationale: The correct technique for transferring a client from a bed to a chair to avoid back injuries is to bend at the knees while maintaining a wide stance and a straight back. This position ensures that the nurse uses leg muscles rather than the back muscles for lifting, reducing the risk of injury. Placing the client's hands on the nurse's shoulders and the nurse's hands under the client's axillae provides additional support and stability during the transfer. Using a mechanical lift may be appropriate for certain situations but is not necessary for a simple bed-to-chair transfer. Twisting at the waist while holding the client can lead to back strain or injury. Asking for assistance from another staff member is a good practice, but proper body mechanics should still be followed to ensure safe client handling.

Correct Answer: C

Rationale: The correct answer is C. Protecting others from exposure when transporting a client with MRSA is crucial in preventing the spread of infection. This statement demonstrates understanding of infection control measures. Stating that MRSA is usually resistant to vancomycin (choice B) is incorrect; vancomycin is often effective against MRSA. Obtaining a specimen for culture and sensitivity after the first dose of an antimicrobial (choice A) is unnecessary and not indicated. Discontinuing antimicrobial therapy when the client is no longer febrile (choice D) is incorrect because antimicrobial therapy should be completed as prescribed to prevent the development of resistant strains.

Correct Answer: A

Rationale: When providing mouth care for an unconscious client, the nurse should turn the client's head to the side. This action helps prevent aspiration by allowing any fluids to drain out of the mouth, reducing the risk of choking or aspiration pneumonia. Placing fingers into the client's mouth can be dangerous and may cause injury. Brushing the client's teeth only once a day may not be sufficient for proper oral hygiene care. Injecting mouth rinse into the center of the mouth is not recommended and can potentially lead to aspiration. Therefore, the correct action for the nurse to take is to turn the client's head to the side.
