Question 1 of 5
Which of the following drugs would be ordered by the physician to improve the platelet count in a male client with idiopathic thrombocytopenic purpura (ITP)?
Correct Answer: B
Rationale: The correct answer is B: Corticosteroids. Corticosteroids are commonly prescribed to increase platelet count in ITP by suppressing the immune system's attack on platelets. ASA (choice A) can actually worsen bleeding in ITP. Methotrexate (choice C) is used for other autoimmune conditions, not ITP. Vitamin K (choice D) is not effective in treating ITP as it is involved in the clotting process, not platelet production.
Question 2 of 5
Rico with diabetes mellitus must learn how to self-administer insulin. The physician has prescribed 10 U of U-100 regular insulin and 35 U of U-100 isophane insulin suspension (NPH) to be taken before breakfast. When teaching the client how to select and rotate insulin injection sites, the nurse should provide which instruction?
Correct Answer: B
Rationale: Step 1: Rotating injection sites helps prevent lipohypertrophy and ensures consistent insulin absorption. Step 2: Rotating within the same region allows for proper absorption without causing tissue damage. Step 3: Injecting into healthy tissue with large blood vessels can lead to erratic absorption. Step 4: Administering into areas of scar tissue or hypotrophy can alter insulin absorption. Step 5: Administering into sites above muscles before exercise can lead to rapid absorption and hypoglycemia.
Question 3 of 5
If a client requires a pneumonectomy, what fills the area of the thoracic cavity?
Correct Answer: C
Rationale: The correct answer is C because after a pneumonectomy, the pleural cavity is filled with serous fluids to prevent collapse and consolidate the region. This fluid helps maintain the integrity of the thoracic cavity structure and prevents the other organs from shifting. Choice A is incorrect because leaving the space filled with air would lead to a collapsed lung and inefficient breathing. Choice B is incorrect as filling the space with a gel would not serve any physiological purpose and could potentially cause complications. Choice D is incorrect as tissue from the other lung does not grow over to the other side to fill the empty space left by the removed lung.
Question 4 of 5
Francis with leukemia has neutropenia. Which of the following functions must frequently assessed?
Correct Answer: D
Rationale: The correct answer is D: Breath sounds. In a patient with neutropenia, there is a higher risk of developing respiratory infections due to low white blood cell count. Assessing breath sounds can help detect early signs of respiratory distress or infection, which can be life-threatening in this population. Blood pressure (A), bowel sounds (B), and heart sounds (C) are important assessments, but in the context of neutropenia, monitoring breath sounds is crucial for early detection and intervention in respiratory complications.
Question 5 of 5
During the administration of chemotherapy agents, Nurse Oliver observed that the IV site is red and swollen, when the IV is touched Stacy shouts in pain. The first nursing action to take is:
Correct Answer: C
Rationale: The correct answer is C: Immediately discontinue the infusion. This action is necessary to prevent further harm to the patient in case of an adverse reaction to the chemotherapy agent. Discontinuing the infusion will stop the administration of the potentially harmful drug and allow for prompt assessment and intervention. Notifying the physician (choice A) can be done after discontinuing the infusion. Flushing the IV line (choice B) may not address the underlying issue of the redness and swelling at the site. Applying an ice pack followed by warm compress (choice D) may provide temporary relief but does not address the need to stop the infusion immediately.
