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.

Correct Answer: B

Rationale: The correct answer is B: Dyspnea on exertion. In older clients, dyspnea on exertion is often the earliest symptom of heart failure due to decreased cardiac reserve. This occurs when the heart cannot pump enough blood to meet the body's demands during physical activity. Increased urine output (A) is not typically an early symptom of heart failure. Swollen joints (C) are more indicative of arthritis or inflammation, not necessarily heart failure. Nausea and vomiting (D) are not typical early symptoms of heart failure and are more commonly associated with gastrointestinal issues.

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.

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.

Correct Answer: B

Rationale: The correct answer is B: Teach him to perform Kegel's exercises 10 to 20 times per hour. This is the appropriate action because Kegel's exercises help strengthen the pelvic floor muscles, which can improve urinary control and reduce dribbling post-TURP. Restricting fluid intake (A) is not necessary and may lead to dehydration. Reinserting the Foley catheter (C) is not recommended as it can increase the risk of infection. Reassuring the patient (D) without providing any intervention is not addressing the issue. Teaching Kegel's exercises is the most effective and non-invasive approach to manage post-TURP dribbling.
