1. A 70-year-old woman has difficulty with driving, and she has been frequently getting lost. Her husband said she has also been acting strange and seems to want to sleep a lot. He said the other night she kept saying she was seeing animals such as lions in her room. He says her memory is not too bad, but he is very concerned about her health. Physical examination reveals an alert woman with stable vital signs. Bradykinesia and limb rigidity are noted. These findings are consistent with:
- A. Alzheimer's disease.
- B. Vascular dementia.
- C. Dementia with Lewy bodies.
- D. Frontotemporal dementia.
Correct answer: C
Rationale: The symptoms described in the scenario, such as visual hallucinations, fluctuations in cognition, and parkinsonism (bradykinesia and limb rigidity), are classic features of dementia with Lewy bodies (DLB). DLB is characterized by the presence of Lewy bodies in the brain, which are abnormal protein deposits. Alzheimer's disease (Choice A) typically presents with memory loss as a predominant symptom, which is not a major concern in this case. Vascular dementia (Choice B) is associated with a history of cerebrovascular disease and is not supported by the symptoms described. Frontotemporal dementia (Choice D) usually presents with changes in behavior and personality, rather than the symptoms described in the scenario.
2. Which of the following is the most likely indication for the use of immunosuppressant agents?
- A. Intractable seizure disorders
- B. Increased intracranial pressure
- C. Organ transplantation
- D. HIV/AIDS with multiple drug resistance
Correct answer: C
Rationale: The correct answer is C: Organ transplantation. Immunosuppressant agents are commonly used in organ transplant recipients to prevent organ rejection by suppressing the immune system. Choices A, B, and D are incorrect. Intractable seizure disorders are often managed with antiepileptic drugs, increased intracranial pressure is managed through various means like surgery and medications, and HIV/AIDS with multiple drug resistance is typically treated with antiretroviral therapy, not immunosuppressant agents.
3. During a follow-up visit, a patient being treated for latent tuberculosis mentions inconsistent drug intake. What should subsequent health education focus on?
- A. The importance of adhering to the treatment regimen to reduce adverse effects
- B. The necessity of consistently taking the prescribed drugs for TB cure
- C. Matching drug dosages carefully to signs and symptoms
- D. The consequence of nonadherence leading to antiretroviral use
Correct answer: B
Rationale: The correct answer is B because consistent intake of prescribed drugs is crucial for curing tuberculosis. By emphasizing the necessity of following the treatment plan, the patient is more likely to achieve a successful outcome. Choice A is incorrect because it focuses on the risk of adverse effects rather than the primary goal of TB cure. Choice C is incorrect as it does not address the issue of inconsistent drug intake. Choice D is also incorrect as it introduces a different treatment (antiretrovirals) not relevant to latent tuberculosis.
4. A nurse is conducting an assessment on a client who presents with symptoms that are characteristic of amyotrophic lateral sclerosis (ALS). What assessment finding would be expected in this client?
- A. Reduced reflexes in all four limbs
- B. Decreased cognitive function
- C. Involuntary muscle contractions
- D. Hyperreflexia
Correct answer: D
Rationale: The correct answer is D: Hyperreflexia. In amyotrophic lateral sclerosis (ALS), hyperreflexia is a common assessment finding due to the degeneration of upper motor neurons. This results in an overactive reflex response to stimuli. Reduced reflexes in all four limbs (choice A) are not typically seen in ALS; instead, hyperreflexia is more common. Decreased cognitive function (choice B) is not a primary characteristic of ALS. Involuntary muscle contractions (choice C) are more indicative of conditions such as dystonia or myoclonus, not ALS.
5. During surgery, the anesthesia personnel notice the client is having a steady rise in end-tidal carbon dioxide level. At this time, the nurse anesthetist begins to assess the client for malignant hyperthermia. The initial (priority) assessment for this disorder may include:
- A. measuring serum potassium levels.
- B. monitoring for muscle rigidity.
- C. evaluating renal function.
- D. checking arterial blood gases.
Correct answer: B
Rationale: The correct answer is B: monitoring for muscle rigidity. Muscle rigidity is a hallmark sign of malignant hyperthermia, a life-threatening condition triggered by certain anesthetics. Monitoring for this sign is critical in the early identification of the condition. Choices A, C, and D are not the initial priority assessments for malignant hyperthermia. Measuring serum potassium levels, evaluating renal function, and checking arterial blood gases are not specific initial assessments for malignant hyperthermia and would not aid in its early identification.
