Correct Answer: A

Rationale: Distraction therapy involves directing attention away from pain towards positive stimuli, which can help reduce the perception of pain. Choice A is the correct answer as it accurately defines distraction therapy. Cognitive reappraisal (Choice B) involves changing the way one thinks about a situation to alter its emotional impact, which is different from distraction therapy. Choice C is incorrect because distraction therapy does not involve replacing images of pain with other images, but rather focusing on something unrelated. Choice D is incorrect as distraction therapy does not necessarily involve medication or meditation, but rather the redirection of attention.

Correct Answer: D

Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.

Correct Answer: C

Rationale: In cases of adenocarcinoma of the rectum with positive peritoneal lymph nodes, the most likely site of metastasis is the liver. Colon tumors commonly spread through the lymphatics and portal vein to the liver. While metastasis to the brain, bone, or mediastinum is possible, the liver is typically the first to be affected due to the anatomical pathways involved in colorectal cancer metastasis. Therefore, the correct answer is the liver. Metastasis to the brain, bone, or mediastinum would be less likely at this stage of colorectal cancer progression.

Correct Answer: D

Rationale: The correct answer is a five-year-old in skeletal traction. This task is within the scope of practice for an LPN and would need minimal assistance from an RN. The children with diabetic ketoacidosis, sickle cell crisis, and dehydration require close observation, good assessment skills, IVF needs, and medications that would be better managed by an RN. Reassigning the child in skeletal traction to an LPN ensures appropriate care while allowing the RN to focus on the more critical cases.

Correct Answer: D

Rationale: The correct answer is extension, flexion, inversion, and eversion. These exercises help assess the full range of motion of the ankles. Flexion and extension evaluate the bending and straightening movements of the ankle joint, respectively. Inversion and eversion assess the inward and outward movements of the foot at the ankle joint. Hyperextension, abduction, and adduction are not specific movements of the ankle joint, making choices A and B incorrect. External and internal rotation are movements more related to joints like the hip or shoulder, not the ankle, making choice C incorrect.
