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: C

Rationale: Step 1: Malnourishment often leads to iron deficiency anemia, causing spoon-shaped nails (koilonychia). Step 2: Koilonychia is a classic sign of chronic malnutrition and iron deficiency. Step 3: Moist lips (A) and pink conjunctivae (B) are not specific to malnourishment. Step 4: Not easily plucked hair (D) is more related to hair health rather than malnutrition.

Correct Answer: B

Rationale: The correct answer is B: Vulvodynia. Vulvodynia is characterized by chronic vulvar pain or discomfort, including stabbing pain and burning, without an identifiable cause. In this case, the young girl is experiencing these symptoms despite not being sexually active, ruling out other conditions like vulvitis (inflammation of the vulva), vaginitis (inflammation of the vagina), and Bartholin's cyst (fluid-filled swelling near the vaginal opening). The absence of sexual activity suggests that the pain is not related to an infection or trauma, further supporting the diagnosis of vulvodynia.

Correct Answer: B

Rationale: The correct answer is B because giving a hypertonic solution enema to a patient with fluid volume excess can worsen the condition by drawing more fluid into the colon. This can lead to further fluid volume overload and electrolyte imbalances. The other choices are incorrect because: A: Normal saline enema is appropriate for constipation. C: Kayexalate enema is used to treat hyperkalemia, not hypokalemia. D: Oil retention enema is indicated for constipation to soften stool.

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.
