The clinical manifestations of Parkinson’s disease (bradykinesia rigidity and tremors) is directly related to a decreased level of:
- A. Acetylcholine
- B. Serotonin
- C. Dopamine
- D. Phenylalanine
Correct Answer: C
Rationale: The correct answer is C: Dopamine. Parkinson's disease is primarily caused by a deficiency of dopamine in the brain, leading to the characteristic symptoms of bradykinesia, rigidity, and tremors. Dopamine is a neurotransmitter involved in movement control. Acetylcholine (Choice A) is not directly related to Parkinson's disease, although its imbalance can contribute to other movement disorders. Serotonin (Choice B) and Phenylalanine (Choice D) are not primarily involved in the pathophysiology of Parkinson's disease.

In assessing clients for pernicious anemia, the nurse should be alert for which of the following risk factors?
- A. Positive family history
- B. Infectious agents or toxins
- C. Acute or chronic blood loss
- D. Inadequate dietary intake
Correct Answer: A
Rationale: The correct answer is A: Positive family history. Pernicious anemia is an autoimmune condition where the body attacks its own intrinsic factor, leading to vitamin B12 deficiency. Genetic predisposition plays a significant role in the development of pernicious anemia. Family history is a key risk factor as individuals with a family history of pernicious anemia are more likely to develop the condition.
Summary of why the other choices are incorrect:
B: Infectious agents or toxins do not directly cause pernicious anemia, although they can lead to other types of anemia.
C: Acute or chronic blood loss can result in iron-deficiency anemia, not pernicious anemia.
D: Inadequate dietary intake of vitamin B12 can lead to vitamin B12 deficiency anemia, but pernicious anemia specifically involves the body's inability to absorb B12 due to intrinsic factor deficiency, not dietary intake alone.
A staff development nurse is providing an inservice for other nurses to educate them about the Nursing Interventions Classification (NIC) system. During the inservice, which statement made by one of the nurses in the room requires the staff development nurse to clarify the information provided? “This system can help medical students determine the cost of the care they provide to
- A. patients.” “If the nursing department uses this system, communication among nurses who work
- B. throughout the hospital may be enhanced.” “We could use this system to help organize orientation for new nursing employees because we can better explain the nursing interventions we use most frequently on our
- C. unit.” “The NIC system provides one way to improve safe and effective documentation in the
- D. hospital’s electronic health record.”
Correct Answer: A
Rationale: The correct answer is A because the Nursing Interventions Classification (NIC) system is not designed to help medical students determine the cost of care. The NIC system focuses on standardizing and categorizing nursing interventions to improve communication, documentation, and patient care. Choice B is incorrect because it correctly identifies one of the benefits of using the NIC system - enhancing communication among nurses. Choice C is incorrect because it suggests a valid use of the NIC system for organizing orientation and explaining nursing interventions. Choice D is incorrect because it accurately states that the NIC system can improve documentation in the electronic health record, which is one of its purposes.
A client seeks care for hopeless that has lasted for 1 month. To elicit the most appropriate information about this problem, the nurse should ask which question.
- A. “Do you smoke cigarettes, cigars or pipe?”
- B. “Have you strained your voice recently?”
- C. “Do you eat a lot of red meat?”
- D. “Do you eat spicy foods?”
Correct Answer: B
Rationale: The correct answer is B: “Have you strained your voice recently?” This question is relevant to the client's symptom of hopeless, as vocal strain can contribute to this issue. Asking about voice strain helps to identify a potential cause and guides further assessment and intervention.
Choice A is not directly related to the client's primary concern and does not address the underlying cause of hopeless.
Choice C is unrelated to the client's symptom and does not provide information that is pertinent to addressing the issue at hand.
Choice D is also unrelated to the client's symptom of hopeless and does not address potential contributing factors.
At the present time, the best treatment for cancer is complete __________ before metastasis occurs:
- A. Chemotherapy
- B. Radiation
- C. Surgical removal
- D. All of the above
Correct Answer: C
Rationale: The correct answer is C: Surgical removal. Surgical removal of the cancerous tumor is the best treatment before metastasis because it physically removes the cancer cells. Chemotherapy and radiation are used to treat cancer after it has spread, not as the primary treatment. Choice D is incorrect because not all types of cancer can be effectively treated with all three options.
The nurse is instructing a client with newly diagnosed hypoparathyroidism about the regimen used to treat this disorder. The nurse should state that the physician probably will prescribe daily supplements of calcium and:
- A. Folic acid
- B. Potassium
- C. Vitamin D
- D. Iron
Correct Answer: C
Rationale: The correct answer is C: Vitamin D. In hypoparathyroidism, there is a deficiency of parathyroid hormone leading to low calcium levels. Vitamin D helps in the absorption of calcium from the intestines, thus aiding in maintaining normal calcium levels. It is often prescribed along with calcium supplements to support bone health and prevent complications. Folic acid (A) is not directly related to the treatment of hypoparathyroidism. Potassium (B) is not typically prescribed for this condition and can be harmful in high levels. Iron (D) is not directly involved in calcium metabolism and is not part of the standard treatment regimen for hypoparathyroidism.
