Reviewing lab results for a client who reports bilateral pain and swelling in her finger joints, with stiffness in the morning- should recognize that an increase in which of the following lab values can indicate arthritis?

Correct Answer: B

Rationale: The correct answer is B: Rheumatoid factor. An increase in rheumatoid factor can indicate arthritis, specifically rheumatoid arthritis, as it is an autoantibody that targets healthy tissue in the joints. This is a key diagnostic marker for rheumatoid arthritis. A: Direct Coomb's test is used to detect antibodies on the surface of red blood cells, not specific to arthritis. C: Blood urea nitrogen (BUN) is a measure of kidney function and not typically associated with arthritis. D: Platelet count is unrelated to arthritis and is more indicative of clotting disorders or other conditions.

Correct Answer: D

Rationale: Iron is primarily absorbed in the duodenum, the first part of the small intestine. The duodenum is where iron is released from food and converted into a form that can be absorbed by the body. The acidic environment in the stomach helps to break down iron-containing compounds, but actual absorption occurs in the duodenum. The ileum and jejunum are also parts of the small intestine, but they are not the primary sites of iron absorption. The stomach is involved in initial digestion but not in the absorption of iron. Therefore, the correct answer is D, the duodenum.

Correct Answer: B

Rationale: World AIDS Day is celebrated on December 1st globally to raise awareness about HIV/AIDS. This date was chosen to honor those who have died from the illness and support those living with it. Option A, May 12th, Option C, July 4th, and Option D, April 1st, are incorrect as they do not correspond to the designated date for World AIDS Day.

Correct Answer: C

Rationale: Rationale: Antibiotics are ineffective in treating irritable bowel syndrome because IBS is not caused by bacterial infections. IBS is a functional disorder of the digestive system. Antibiotics do not target the underlying causes of IBS such as altered gut motility or visceral hypersensitivity. Therefore, using antibiotics to treat IBS would not address the root of the problem and would be ineffective. Other choices are incorrect because antibiotics are not the primary treatment for IBS, they are not used for pain relief in IBS, and there is no age restriction for prescribing antibiotics in IBS treatment.

Correct Answer: D

Rationale: The correct first nursing action is to apply an ice pack and compression dressings to the knee. This is to reduce swelling and control bleeding in the affected area, which is crucial for a client with hemophilia. Initiating an IV site for cryoprecipitate or type and cross-matching for transfusion may be necessary later, but the priority is to manage the immediate swelling and bleeding. Monitoring vital signs can wait until the initial intervention of addressing the knee swelling is done. This choice helps stabilize the client's condition and prevent further complications.
