What is the most common cause of dementia among elderly persons?

A. Parkinson’s disease

B. Multiple sclerosis

C. Amyotrophic lateral sclerosis (Lou Gehrig’s disease)

D. Alzheimer’s disease

Correct Answer: D
Rationale: Alzheimer’s disease is the most common cause of dementia among elderly persons. It is a progressive neurodegenerative disorder that affects memory, thinking, and behavior. While Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis are serious conditions, they are not typically associated with dementia in the same way Alzheimer’s disease is. Therefore, the correct answer is D.

What is the most appropriate nursing order for a patient who develops dyspnea and shortness of breath?

• A. Maintain the patient on strict bed rest at all times
• B. Maintain the patient in an orthopneic position as needed
• C. Administer high-flow oxygen immediately
• D. Encourage the patient to engage in vigorous physical activity

Correct Answer: B
Rationale: Maintaining the patient in an orthopneic position as needed is the most appropriate nursing order for a patient experiencing dyspnea and shortness of breath. This position helps to optimize lung expansion, improve oxygenation, and alleviate breathing difficulties. It is a strategic intervention to enhance respiratory function in patients with respiratory distress. Choice A is incorrect because strict bed rest may not address the underlying respiratory issue effectively. Choice C is premature as administering high-flow oxygen should be based on a comprehensive assessment. Choice D is inappropriate as encouraging vigorous physical activity can exacerbate breathing problems in a patient experiencing dyspnea.

If a patient asks the nurse for her opinion about a particular physician and the nurse replies that the physician is incompetent, the nurse could be held liable for:

• A. Slander
• B. Libel
• C. Assault
• D. Respondent superior

Correct Answer: A
Rationale: In this scenario, if the nurse makes a false verbal statement about the physician being incompetent, it is considered slander. Slander is the act of making defamatory spoken statements or gestures. Libel, on the other hand, refers to defamatory statements that are written or published. Assault involves the threat of physical harm, and respondent superior is a legal doctrine holding an employer responsible for the actions of an employee in the course of employment.

While caring for a client in a clinic, a healthcare professional learns that the client woke up not recognizing their partner, surroundings, has chills, and chest pain worsening upon inspiration. What should be the healthcare professional's priority action?

• A. Obtain baseline vital signs and oxygen saturation.
• B. Obtain a sputum culture.
• C. Obtain a complete history from the client.
• D. Provide a pneumococcal vaccine.

Correct Answer: Obtain baseline vital signs and oxygen saturation.
Rationale: The priority action for the healthcare professional is to obtain the client's baseline vital signs and oxygen saturation. This will provide essential information on the client's current physiological status and help guide further assessment and intervention. Assessing the vital signs and oxygen saturation can help identify any immediate concerns like hypoxia or sepsis, which require prompt attention. While obtaining a complete history and considering a pneumococcal vaccine may be important in the overall care of the client, assessing the vital signs and oxygen saturation takes precedence to address the client's immediate physiological needs.

When caring for a toddler with acute lymphocytic leukemia, in which of the following activities should the toddler participate?

• A. Looking at alphabet flashcards.
• B. Playing with a large plastic truck.
• C. Using scissors to cut out paper shapes.
• D. Watching a cartoon in the dayroom.

Correct Answer: Playing with a large plastic truck.
Rationale: Toddlers with acute lymphocytic leukemia may have compromised immune systems and need to avoid activities that increase infection risk. Playing with a large plastic truck is a safe and engaging activity that does not pose a high risk of infection. This choice also promotes physical activity and creativity, which are beneficial for a toddler's development during illness.
