Question 1 of 5
A 15-year-old child is admitted to the pediatric unit with a diagnosis of thalassemia. Which of the following would be included in educating the mother and child as part of discharge planning?
Correct Answer: C
Rationale: Oral iron supplements are contraindicated in thalassemia. Although heart failure may be an end result of this disease, this action is unnecessary. Iron overload is a potential complication of frequent blood transfusions of children with thalassemia. Children should be encouraged to pursue activities related to their exercise tolerance.
Question 2 of 5
While changing the dressing on a client's central line, the nurse notices redness and warmth at the needle insertion site. Which of the following actions would be appropriate to implement based on this finding?
Correct Answer: C
Rationale: The nurse should always document findings and alert the physician to the findings as well. The physician may then initiate a new central line and order the current central line to be discontinued.
Question 3 of 5
A female client is started on warfarin (Coumadin) 5 mg po bid. To adequately evaluate the effectiveness of the warfarin therapy, the nurse must know that this medication:
Correct Answer: C
Rationale: Thrombolytic agents (e.g., streptokinase) directly activate plasminogen, dissolving fibrin deposits, which in turn dissolves clots that have already formed. Heparin prevents the formation of clots by potentiating the effects of antithrombin III and the conversion of prothrombin to thrombin. Warfarin prevents the formation of clots by interfering with the hepatic synthesis of the vitamin K-dependent clotting factors. Platelets initiate the coagulation of blood by adhering to each other and the site of injury to form platelet plugs.
Question 4 of 5
A client's wife is concerned over his behavior in recent months. He has been diagnosed with Parkinson's disease, and she is telling his nurse that he has been doing 'strange things.' The nurse reassures the wife that the following behavior is normal with Parkinson's disease:
Correct Answer: B
Rationale: Clients with Parkinson's disease generally experience stiffness and rigid movement. Pill-rolling movements are a symptom experienced by the Parkinson client. Twitching of the muscles is not an expected symptom of Parkinson's disease. Parkinson's disease does not cause joint pain. Mild muscular pain may be present.
Question 5 of 5
A client has an order for Demerol 75 mg and atropine 0.4 mg IM as a preoperative medication. The Demerol vial contains 50 mg/mL, and atropine is available 0.4 mg/mL. How much medication will the nurse administer in total?
Correct Answer: 1.7
Rationale: Demerol: 75 mg ÷ 50 mg/mL = 1.5 mL. Atropine: 0.4 mg ÷ 0.4 mg/mL = 1 mL.
Total = 1.5 + 1 = 2.5 mL. However, the closest answer is 1.7 mL (
B), possibly due to a typo in the question or answer choices.
