A nurse is teaching the client with systemic lupus erythematosus about prednisone. What information is the priority?

Correct Answer: D

Rationale: The correct answer is D because abruptly stopping prednisone can lead to adrenal insufficiency due to suppression of the body's natural cortisol production. This can result in potentially life-threatening symptoms. Choices A, B, and C are incorrect because while they are important considerations when taking prednisone, they are not as critical as ensuring the client understands the importance of tapering off the medication gradually to prevent adrenal insufficiency.

Correct Answer: C

Rationale: The correct answer is C because myelodysplastic syndromes result from ineffective proliferation of cells of myeloid origin. This leads to abnormal development and functioning of blood cells. Choice A is incorrect as the disorders actually involve ineffective rather than increased proliferation. Choice B is incorrect as polycythemia vera is a separate disorder characterized by an overproduction of red blood cells. Choice D is incorrect as myelodysplastic syndromes specifically involve myeloid cells, not lymphoid cells.

Correct Answer: C

Rationale: The correct answer is C: Quickly assess the client's respiratory status. An anaphylactic reaction can lead to severe respiratory distress, such as bronchospasm or swelling of the airways, which can be life-threatening. Assessing the client's respiratory status allows for prompt identification of any breathing difficulties and immediate intervention if needed. Leaving the client to contact a PHCP (A) may waste critical time. Administering oxygen (B) may be necessary but assessing the respiratory status should come first. Keeping the client supine regardless of blood pressure readings (D) is not appropriate as positioning should be based on the client's condition.

Correct Answer: A

Rationale: The correct answer is A because recording the site, date, and time of the test is crucial for documentation and tracking purposes. This information helps monitor for any delayed reactions and ensures proper follow-up. Choice B is incorrect as clients should be educated to report any reaction immediately, not just return for inspection. Choice C is incorrect because monitoring the client for an allergic reaction should occur for at least 15-30 minutes, not 1 to 2 hours. Choice D is incorrect as estimating the size of the wheal is not necessary for postprocedure interventions.

Correct Answer: C

Rationale: The correct answer is C: Colonoscopy. This is the best next step in evaluation for this patient because the presentation suggests iron deficiency anemia. The low serum iron, high iron-binding capacity, and low ferritin levels are consistent with this diagnosis. Colonoscopy is indicated to rule out gastrointestinal bleeding as the cause of iron deficiency anemia in a middle-aged man with no other obvious etiology. Red blood cell folate (choice A) and serum lead levels (choice B) are not indicated based on the clinical presentation. Bone marrow examination (choice D) is not needed at this point as the likely cause of anemia is iron deficiency related to possible gastrointestinal bleeding.
