1. The doctor orders 2% nitroglycerin ointment in a 1-inch dose every 12 hours. Proper application of nitroglycerin ointment includes:
- A. Rotating application sites
- B. Limiting applications to the chest
- C. Rubbing it into the skin
- D. Covering it with a thin paper dressing
Correct answer: A
Rationale: Proper application of nitroglycerin ointment involves rotating application sites to prevent skin irritation. It should be applied to the back and upper arms, not restricted to the chest, making option B incorrect. Rubbing it into the skin, as indicated in option C, is not recommended for nitroglycerin ointment as it can lead to faster absorption and potential side effects. The correct way is to cover it with a thin paper dressing, not gauze as mentioned in option D, to ensure proper absorption and prevent the medication from evaporating too quickly.
2. A client with cancer develops xerostomia. The nurse can help alleviate the discomfort associated with xerostomia by:
- A. Offering hard candy
- B. Administering analgesic medications
- C. Splinting swollen joints
- D. Providing saliva substitute
Correct answer: D
Rationale: Xerostomia is dry mouth, a common side effect in cancer patients. Providing a saliva substitute helps alleviate the discomfort associated with dry mouth by moistening the oral mucosa. Offering hard candy, as mentioned in choice A, can worsen xerostomia by increasing sugar content and potentially causing irritation. Administering analgesic medications, as in choice B, is not directly related to treating dry mouth. Splinting swollen joints, as in choice C, is irrelevant to xerostomia, which primarily affects the oral cavity.
3. A complication of total parenteral nutrition (TPN) is the development of cholestasis. What is this condition?
- A. an inflammatory process of the extrahepatic bile ducts
- B. an arrest of the normal flow of bile
- C. an inflammation of the gallbladder
- D. the formation of gallstones
Correct answer: B
Rationale: Cholestasis due to TPN administration is an intrahepatic process that interrupts the normal flow of bile. It is characterized by a reduction or stoppage of bile flow. Choice A, an inflammatory process of the extrahepatic bile ducts, refers to cholangitis, not cholestasis. Choice C, an inflammation of the gallbladder, describes cholecystitis, a different condition. Choice D, the formation of gallstones, is not correct as cholestasis is about the flow of bile, not the formation of gallstones.
4. While the client is receiving total parenteral nutrition (TPN), which lab test should be evaluated?
- A. Hemoglobin
- B. Creatinine
- C. Blood glucose
- D. White blood cell count
Correct answer: C
Rationale: When a client is receiving total parenteral nutrition (TPN), monitoring blood glucose levels is crucial as TPN solutions contain high amounts of glucose. This monitoring helps prevent hyperglycemia or hypoglycemia. Evaluating hemoglobin (choice A) is not directly related to TPN administration. Creatinine (choice B) is more relevant for assessing kidney function. White blood cell count (choice D) is important for evaluating immune function and infection, but not specifically tied to TPN administration.
5. In the United States, several definitions of death are currently being used. The definition that uses apnea testing and pupillary responses to light is termed:
- A. whole brain death.
- B. heart-lung death.
- C. circulatory death.
- D. higher brain death.
Correct answer: A
Rationale: The correct answer is 'whole brain death.' Most protocols for determining whole brain death require two separate clinical examinations, including the induction of painful stimuli, pupillary responses to light, oculovestibular testing, and apnea testing. This comprehensive approach ensures that all functions of the brain, including the brainstem, are evaluated to confirm the absence of brain function. Choices B and D are incorrect as they do not reflect the specific tests required for determining whole brain death. Choice C, 'circulatory death,' does not involve the evaluation of brain function and is not a current definition of death in the United States.
