Correct Answer: B

Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.

Correct Answer: D

Rationale: The correct answer is D: Inspect feet daily for cuts or sores. Daily foot inspection is crucial for clients with diabetes to detect early signs of injury or infection. Soaking feet in warm water daily (choice A) can lead to skin maceration, making the skin more susceptible to breakdown. Applying moisturizer between the toes (choice B) can increase moisture and the risk of fungal infections. While wearing cotton socks (choice C) is beneficial for diabetic foot care, it is not as crucial as daily foot inspections to prevent complications.

Correct Answer: D

Rationale: In managing GERD, dietary modifications play a significant role. Avoiding spicy and fatty foods helps reduce irritation, while eating small, frequent meals prevents overeating, which can trigger reflux. Avoiding meals before bedtime allows for better digestion and reduces the likelihood of acid reflux during the night. Therefore, all of the options (A, B, and C) are crucial in managing GERD symptoms, making choice D the correct answer.

Correct Answer: D

Rationale: In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This finding indicates impaired liver function affecting the synthesis of clotting factors, leading to an increased risk of bleeding. Elevated AST and ALT levels (Choice A) indicate liver cell damage but do not directly correlate with the risk of bleeding. A decreased albumin level (Choice B) is common in liver disease but is not the most concerning in terms of bleeding risk. Elevated bilirubin levels (Choice C) are seen in liver disease but do not directly reflect the risk of bleeding as PT/INR values do.

Correct Answer: C

Rationale: The correct answer is C. LPNs are trained to provide basic nursing care such as wound care. Providing wound care for a stage III pressure ulcer falls within the LPN's scope of practice. Administering IV medication (choice A) requires a higher level of skill and is usually the responsibility of registered nurses. Conducting initial client assessments (choice B) demands more advanced training and is typically performed by registered nurses. Teaching a diabetic client about insulin administration (choice D) involves patient education and is usually within the scope of registered nurses or other healthcare professionals with specific training in diabetic care.
