Question 1 of 5
Clients receiving antipsychotic drug therapy will often exhibit extrapyramidal side effects that are reversible with which of the following agents ordered by the physician?
Correct Answer: B
Rationale: This answer is incorrect. Phenothiazines are antipsychotic drugs and produce the symptoms. This answer is correct. Anticholinergic agents are often used prophylactically for extrapyramidal symptoms. They balance cholinergic activity in the basal ganglia of the brain. This answer is incorrect. Anti-Parkinsonian drugs would increase the symptoms. This answer is incorrect. Tricyclic agents are used for symptoms of depression.
Question 2 of 5
A 4-week-old infant is admitted to the emergency room in respiratory distress. Which of the following statements indicates the nurse's knowledge of the anatomy of the respiratory system in pediatric clients?
Correct Answer: A
Rationale: The airway in children is much smaller than it is in adults. The diameter of the trachea in the newborn is 4 mm and that of the adult is 20 mm. A small change in the diameter of the airway can make a major difference in the pediatric client. The tongue is proportionally larger in children and fills most of the oral cavity, thereby decreasing air space. The entire pediatric airway is elastic. Elasticity diminishes with age, however. The distances between respiratory structures are shorter than that of adults, and therefore organisms are able to move more rapidly down the throat, leading to more extensive respiratory involvement.
Question 3 of 5
The nurse is caring for a client with a history of peptic ulcer disease. Which food should the client avoid?
Correct Answer: A
Rationale: Spicy foods can irritate the gastric mucosa, exacerbating peptic ulcer disease. Apples, rice, and milk (in moderation) are generally safe.
Question 4 of 5
The client has an order for Garamycin (gentamicin) to be administered. Which lab test should be done before beginning the medication?
Correct Answer: B
Rationale: Gentamicin, an aminoglycoside, is nephrotoxic. Serum creatinine is monitored before administration to assess baseline kidney function, as impaired renal function increases toxicity risk. Hematocrit, white cell count, and BUN are less specific for gentamicin.
Question 5 of 5
Which of the following lab data is representative of a client with aplastic anemia?
Correct Answer: D
Rationale: (A, B,
C) Although all of the lab data are abnormal and although these values are decreased in aplastic anemia, the disorder is defined by severe deficits in red cell, white cell, and platelet counts. Aplastic anemia is typically defined in terms of abnormalities of red blood cell count, usually <1 million, white cell count <2,000, and thrombocytes <20,000.
