Correct Answer: C

Rationale: The rule of nines is a method used to estimate the extent of burns on a patient's body. According to this rule, each major body part is assigned a percentage value that represents the total body surface area (TBSA). In this case, Mr. Kawasaki has second-degree burns on his right leg and arm (9% each) and left leg (9%) and third-degree burns on his left arm (9%). Adding these percentages together, we get a total of 36%, which corresponds to the extent of burn on Mr. Kawasaki's body. Choice A (18%) is incorrect because it only considers one arm and one leg, neglecting the other affected areas. Choice B (45%) is incorrect as it overestimates the extent of burns by including additional body parts not affected. Choice D (54%) is also incorrect as it includes more body parts than those actually burned. Therefore, the correct answer is C (36%) as it accurately reflects the distribution of burns based

Correct Answer: A

Rationale: Step-by-step rationale for why answer A is correct: 1. Positive reinforcement helps enhance communication skills in individuals with expressive aphasia. 2. Providing positive feedback when Mr. Reyea uses words correctly encourages him to continue trying to communicate. 3. It boosts his confidence and motivation, leading to improved verbal communication over time. Summary of why other choices are incorrect: B. Waiting indefinitely for Mr. Reyea to verbally state his needs may lead to frustration and hinder effective communication. C. Suggesting permanent help at home assumes Mr. Reyea's condition cannot improve, which is not necessarily true for expressive aphasia. D. Helping the family accept Mr. Reyea's communication challenges does not actively support his communication improvement and may limit his progress.

Correct Answer: C

Rationale: The correct answer is C: Listen and show interest as the client expresses feelings. It is essential for the nurse to actively listen and show empathy towards the client's emotional distress. This approach demonstrates compassion, understanding, and support for the client during a vulnerable moment, which is crucial for the therapeutic relationship. By actively listening, the nurse can validate the client's emotions and provide a safe space for them to express their feelings. This can help the client feel heard and supported, leading to improved emotional well-being. Choices A, B, and D are incorrect: A: Continuing with the bath and telling the client not to worry dismisses the client's emotions and fails to address their underlying feelings of loneliness and isolation. B: Asking for a psychiatric consultation may not be necessary at this point, as the client's emotional distress can be effectively managed through therapeutic communication. D: Stating that the friends' behavior shows they aren't true friends is judgmental and unhelpful, as it does not address

Correct Answer: B

Rationale: The correct answer is B: 2.0mEq/L. Severe vomiting can lead to hypokalemia, characterized by flat T waves and ST segment depression on ECG. This is due to decreased potassium levels affecting cardiac repolarization. A potassium level of 2.0mEq/L is dangerously low and consistent with the ECG findings in this scenario. Choices A, C, and D have potassium levels that are not reflective of severe hypokalemia, therefore they are incorrect. Option A (4.0mEq/L) is within the normal range, option C (8.0mEq/L) is elevated, and option D (2.6mEq/L) is higher than the correct value of 2.0mEq/L.

Correct Answer: A

Rationale: The correct answer is A because wearing gloves during all client contact is a key practice in standard precautions to prevent the spread of infection. Gloves act as a barrier to protect both the healthcare worker and the patient from potential pathogens. Choice B is incorrect as cleaning blood spills with soap and water is not sufficient for infection control. Choice C is incorrect because pouring bulk blood and secretions down a drain is a violation of biohazard disposal protocols. Choice D is incorrect as carrying a blood sample in an open basket can lead to potential exposure to bloodborne pathogens.
