Correct Answer: A

Rationale: The correct instruction for a patient with stomatitis is to avoid commercial mouthwashes. Commercial mouthwashes often contain alcohol and other ingredients that can irritate the already inflamed oral mucosa in patients with stomatitis. Avoiding commercial mouthwashes helps prevent further irritation and discomfort. Choice B is incorrect because normal saline rinses are gentle and can help soothe the oral mucosa in patients with stomatitis. Choice C is incorrect because a soft toothbrush should be used to prevent further irritation or injury to the gums. Choice D is incorrect because an alcohol-based toothpaste can be too harsh and drying for patients with stomatitis.

Correct Answer: C

Rationale: Tuberculosis is transmitted through airborne particles, so airborne precautions are necessary to prevent the spread of the disease. Airborne precautions (Choice C) involve measures such as negative pressure rooms and N95 respirators to prevent the transmission of infectious agents that remain infectious over long distances when suspended in the air. Contact precautions (Choice A) are used for diseases that spread through direct contact with the patient or their environment. Droplet precautions (Choice B) are for diseases transmitted through respiratory droplets, typically over short distances. Protective environment (Choice D) is used for clients who are immunocompromised to protect them from environmental pathogens, not for diseases like tuberculosis that spread through the air.

Correct Answer: C

Rationale: The correct answer is C - 'Reapplying a condom catheter for a client who has urinary incontinence.' This task falls within the scope of duties for an assistive personnel (AP). Updating care plans (Choice A), reinforcing teaching (Choice B), and applying sterile dressings (Choice D) typically require a higher level of training and expertise, making them tasks that should not be assigned to an AP. Assigning appropriate tasks based on skill levels ensures safe and effective patient care.

Correct Answer: B

Rationale: Choice B is the correct answer because the family member's actions in administering the rectal suppository were correct. Providing positive feedback and asking if there were any problems with the insertion is an appropriate response. Choice A is incorrect because there is no need to have the client turn back to the left side after the suppository has been administered. Choice C is incorrect as there is no indication that the suppository was not inserted correctly, so there is no need to check if it is in far enough. Choice D is incorrect because feeling stool in the intestinal tract is not relevant to the administration of a rectal suppository.

Correct Answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.
