Correct Answer: C

Rationale: The nurse most likely observed plantar warts, which appear on the sole of the foot and are caused by the papillomavirus. Corns (Choice A) and calluses (Choice B) are areas of thickened skin caused by pressure or friction and are not typically associated with viruses. Athlete's foot (Choice D) is a fungal infection that usually affects the skin between the toes and is not caused by a virus like plantar warts.

Correct Answer: A

Rationale: The correct response is to ask the client about their concerns regarding being without their teeth. This approach helps address the client's anxiety and provides insight into the reason for their agitation. Choice B is authoritarian and does not address the client's emotional needs. Choice C focuses on the technical aspect of surgery and does not address the client's emotional state. Choice D implies a one-way communication without addressing the client's feelings or concerns.

Correct Answer: A

Rationale: Choice A is correct because applying oxygen through a tube in the nose provides comfort and aligns with the client's wishes for palliative care without resuscitation. This intervention can help alleviate breathing difficulties and maintain comfort without initiating full resuscitation efforts, respecting the client's decision. Choice B is incorrect as it goes against the client's expressed wish to decline resuscitation in her living will. Choice C is not the most appropriate response as it does not directly address the client's immediate concern of difficulty breathing and lacks specificity. Choice D, although focusing on comfort measures, is less specific than the correct choice A in addressing the client's immediate need for assistance with breathing.

Correct Answer: D

Rationale: To ensure the safe movement of a patient who is unable to move and needs to be pulled up in bed, it is essential to use a friction-reducing device. This device helps reduce the risk of injury to both the patient and the healthcare provider by minimizing the effort required to reposition the patient. Placing a pillow under the patient's head and shoulders (Choice A) may provide comfort but does not address the safety concerns associated with moving the patient. Attempting to move the patient alone (Choice B) is not recommended as it can lead to injuries for both the patient and the healthcare provider. Placing the side rails in the up position (Choice C) may not directly contribute to the safe movement of the patient in this scenario.

Correct Answer: C

Rationale: In a 2-year-old child with diarrhea and a possible ear infection, rectal temperature measurement is the most accurate reflection of core body temperature. This method provides the most reliable reading, especially in young children, as it closely reflects the core body temperature. Oral temperature may not be accurate due to the child's recent diarrhea, which can affect oral readings. Axillary temperature may not be as accurate as rectal temperature in this case. Temporal temperature measurement, although non-invasive, may not provide the most accurate core body temperature reading, especially in a child with a potential ear infection.
