Correct Answer: D

Rationale: Correct Answer: D - Avoid rubbing or scratching the affected area Rationale: 1. Rubbing or scratching can further damage the already compromised skin integrity. 2. By avoiding rubbing or scratching, the patient reduces the risk of infection and delayed healing. 3. This intervention promotes skin healing and prevents worsening of the condition. Summary: A: Applying ice pack or heating pad may provide temporary relief but does not address the root cause of impaired skin integrity. B: Avoiding skin contact with water is not necessary and may not directly improve skin integrity. C: Phototherapy is not indicated for erythematous reactions to radiation therapy and may not address the issue.

Correct Answer: A

Rationale: The correct answer is A: Ewald tube. This tube is used for gastric lavage due to its large diameter and open end which allows for effective suction of gastric contents. The Ewald tube is specifically designed for gastric lavage and is ideal for removing toxins from the stomach. Summary of why the other choices are incorrect: B: Dobhoff tube is a small-bore feeding tube, not suitable for gastric lavage. C: Miller-Abbott tube is used for intestinal decompression, not gastric lavage. D: Sengstaken-Blakemore tube is used for esophageal varices, not gastric lavage.

Correct Answer: C

Rationale: The correct answer is C because primary brain tumors originate from cells within the brain itself. These tumors develop from abnormal growth of brain cells. Choice A is incorrect as primary brain tumors do not come from outside the central nervous system (CNS). Choice B is incorrect as primary brain tumors do not typically start in glands. Choice D is incorrect as primary brain tumors do not arise from nerve tissue elsewhere in the body. In summary, the nurse should explain to the patient that the tumor originated from cells within his brain to provide accurate information about the nature of primary brain tumors.

Correct Answer: A

Rationale: The correct answer is A: Liver function tests (LFTs). Yellow skin can indicate jaundice, a sign of liver dysfunction, often seen in patients with liver issues or chemotherapy-related liver toxicity. LFTs including bilirubin, ALT, AST, and ALP can help assess liver function. B: Complete blood count (CBC) and C: Platelet count are not directly related to yellow skin and would not provide information on liver function. D: Blood urea nitrogen and creatinine are tests for kidney function, not liver function. While kidney dysfunction can sometimes cause yellow skin, LFTs are more specific for assessing liver function in this context.

Correct Answer: A

Rationale: The correct answer is A: Utilize a pressure-reducing mattress. This intervention is crucial for preventing pressure ulcers in patients at risk for impaired skin integrity, such as those with HIV. By redistributing pressure, a pressure-reducing mattress helps to alleviate pressure on vulnerable areas, reducing the risk of skin breakdown. Limiting physical activity (B) can lead to muscle atrophy and worsen skin integrity. Applying antibiotic ointment (C) may not address the root cause of skin breakdown. Avoiding synthetic fabrics (D) may be helpful in some cases, but it is not as effective as using a pressure-reducing mattress.
