Correct Answer: B

Rationale: The highest priority intervention in this scenario is B, the use of careful hand washing technique. Proper hand hygiene is essential in preventing infection, especially in individuals with compromised skin integrity like those with burns. By practicing careful hand washing, healthcare providers reduce the risk of introducing harmful pathogens to the burn wound, thus lowering the chances of infections. Choice A, application of topical antibacterial cream, is important but should follow ensuring proper hand hygiene. Choice C, administration of plasma expanders, is not directly associated with preventing burn-related infections. Choice D, limiting visitors, is significant for infection control, but ensuring proper hand hygiene outweighs this intervention in terms of priority.

Correct Answer: B

Rationale: The correct answer is B. Sodium levels can affect lithium levels in the body, so it is crucial to monitor sodium intake to prevent toxicity or subtherapeutic levels. Lithium is typically taken on an empty stomach to enhance absorption, making choice A more accurate than the original 'Take the medication with food.' Reporting weight gain, as mentioned in choice C, is important for monitoring side effects but is not as critical as ensuring proper lithium levels through sodium intake monitoring. Choice D, avoiding excessive caffeine intake, is not a priority concern directly related to lithium therapy.

Correct Answer: D

Rationale: The best response for the nurse to support a client expressing frustration over their chronic illness is to validate their feelings and listen to their concerns (Option D). This approach helps acknowledge the client's emotions, demonstrates empathy, and establishes a therapeutic relationship. By validating the client's feelings and actively listening to their concerns, the nurse offers a supportive environment for the client to express their frustrations. Choices A, B, and C are not the best responses in this situation. While joining a support group, discussing a cure, or focusing on positive aspects can be beneficial interventions, the immediate priority is to validate the client's feelings and provide a space for them to express their frustrations.

Correct Answer: D

Rationale: Monitoring daily weight, electrolyte levels, and urine output is crucial in evaluating treatment effectiveness for heart failure. Daily weight monitoring helps assess fluid retention or loss, changes in electrolyte levels can indicate imbalances affecting heart function, and urine output monitoring provides insights into kidney function and fluid balance. Therefore, all options are essential components in assessing the patient's fluid status and response to treatment, making 'All of the above' the correct answer. Choices A, B, and C are incorrect individually as they only represent partial aspects of monitoring heart failure treatment effectiveness.

Correct Answer: A

Rationale: The correct measure for skin care after external radiation treatment is to cleanse the radiated area with water and pat the skin dry. This gentle cleansing without harsh chemicals or friction helps protect the integrity of radiated skin, preventing irritation or further damage. Choice B is incorrect because massaging radiated skin can cause further irritation, which should be avoided. Choice C is incorrect as rinsing with normal saline and covering with a sterile towel may not be necessary and could potentially introduce infection due to excessive moisture. Choice D is incorrect as using a soft washcloth to remove skin markings can be too abrasive for radiated skin, risking damage and irritation.
