A client presents with symptoms suggestive of rheumatoid arthritis. Which of the following laboratory tests should be ordered to confirm this diagnosis?

Correct Answer: B

Rationale: Rheumatoid factor is a specific marker for rheumatoid arthritis. It is often elevated in clients with this autoimmune condition, helping to confirm the diagnosis. Erythrocyte sedimentation rate (ESR) and antinuclear antibody tests can be supportive but are not specific for rheumatoid arthritis. Serum calcium levels are not typically used to confirm this diagnosis.

Correct Answer: C

Rationale: The correct answer is C: Flat affect. Negative symptoms of schizophrenia involve deficits in normal emotional responses or other thought processes. These symptoms include a flat affect (reduced emotional expression), social withdrawal, and avolition (lack of motivation). Hallucinations and delusions are characteristic of positive symptoms, which involve the presence of abnormal behaviors or experiences. Paranoia is more associated with delusions rather than negative symptoms.

Correct Answer: A

Rationale: The correct answer is A: Butterfly rash on the face. A butterfly-shaped rash across the nose and cheeks is a classic symptom of systemic lupus erythematosus (SLE), an autoimmune disease. Weight gain (Choice B) is not typically associated with SLE. Joint deformities (Choice C) are more commonly seen in conditions like rheumatoid arthritis. Increased hair growth (Choice D) is not a typical finding in SLE.

Correct Answer: C

Rationale: In acute pancreatitis, the nurse should expect elevated blood glucose levels. This is due to impaired insulin production by the inflamed pancreas. While serum amylase and lipase levels are typically elevated in acute pancreatitis, blood glucose levels are also affected due to the pancreatic dysfunction. Therefore, choices A and B are incorrect. Elevated calcium levels are not typically associated with acute pancreatitis, making choice D incorrect.

Correct Answer: D

Rationale: The correct answer is D: 'You may experience diarrhea with this medication.' Diarrhea is a common side effect of metformin, particularly when initiating the medication. It is important for clients to be aware of this potential side effect. Option A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Option B is not directly related to metformin use. Option C is incorrect as muscle pain is not a common side effect of metformin and does not warrant stopping the medication.

Correct Answer: A

Rationale: Administering oxygen is the priority intervention for a client with a pulmonary embolism. Pulmonary embolism can lead to impaired gas exchange, causing hypoxemia. Administering oxygen helps to maintain adequate oxygenation levels. Thoracentesis is not indicated for a pulmonary embolism, as it is a procedure to remove fluid or air from the pleural space, not a treatment for embolism. Elevating the client's lower extremities is not a priority in the management of a pulmonary embolism. Administering anticoagulant therapy is important in the treatment of pulmonary embolism to prevent further clot formation, but it is not the first intervention. Oxygen administration takes precedence to address the immediate oxygenation needs of the client.

Correct Answer: A

Rationale: The correct answer is A. Ibuprofen can increase the risk of bleeding when taken with warfarin, as both medications affect clotting. The client should use alternative pain relievers like acetaminophen. Choice B is correct as using an electric razor is a safe choice to prevent cuts that could lead to bleeding. Choice C is correct as warfarin interacts with vitamin K found in leafy green vegetables. Choice D is correct as regular blood level checks are necessary to monitor the effects and adjust the warfarin dosage if needed.

Correct Answer: C

Rationale: The correct action for the nurse to take before performing a closed intermittent bladder irrigation is to apply sterile gloves. Sterile gloves help maintain asepsis, reduce the risk of infection, and ensure patient safety during the procedure. Aspirating the irrigation solution from the bladder (Choice A) is not a standard step in closed intermittent bladder irrigation. Inserting the tip of the irrigation syringe into the catheter opening (Choice B) can introduce contaminants into the system. Opening the flow clamp to the irrigating fluid infusion tubing (Choice D) should only be done after ensuring all equipment is ready and the nurse is gloved to maintain sterility.

Correct Answer: C

Rationale: The correct recommendation for a patient receiving chemotherapy and experiencing nausea is to suggest eating dry, bland foods like cereal. These types of foods are often better tolerated as they are less likely to trigger nausea compared to aromatic or hot foods. Drinking liquids between meals, as suggested in option B, can be helpful to prevent dehydration but may not specifically address the nausea. Eating foods with a strong aroma, as in option D, may actually worsen nausea in patients undergoing chemotherapy.
