Nclex Exam Cram Practice Questions
1. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?
- A. serotonin
- B. cortisol
- C. alcohol
- D. narcotics
Correct answer: A
Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.
2. An 85-year-old client is eligible for Medicare-reimbursable home care services. Referral is contingent on meeting which of the following criteria?
- A. homebound status, requiring skilled therapy care
- B. immediate previous hospitalization for acute care
- C. age
- D. requirement of nursing and social work support
Correct answer: A
Rationale: The correct criteria for Medicare-reimbursable home care services include the client being homebound and requiring a skilled service, such as physical therapy, occupational therapy, speech therapy, nursing, or social work. Choice A is correct because it aligns with these requirements. Choice B is incorrect as immediate previous hospitalization is not a prerequisite for home care services. Choice C is incorrect as age alone does not determine eligibility for Medicare-reimbursable home care services. Choice D is incorrect as the requirement of nursing and social work support alone is not sufficient for Medicare-reimbursable home care services.
3. The nurse is teaching a client about communicable diseases and explains that a portal of entry is:
- A. a vector.
- B. a source, like contaminated water.
- C. food.
- D. the respiratory system.
Correct answer: D
Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.
4. Hearing screening of prematurely born infants is an effective means of identifying disease and is an example of:
- A. Primary prevention.
- B. Secondary prevention.
- C. Tertiary prevention.
- D. Disability prevention.
Correct answer: B
Rationale: The correct answer is B: Secondary prevention. Hearing screening for prematurely born infants falls under secondary prevention, which aims to identify and treat a condition in its early stages to prevent further complications. Primary prevention (choice A) focuses on preventing the disease from occurring, while tertiary prevention (choice C) involves managing complications and preventing disability. Choice D, disability prevention, is not a recognized category of prevention. In this context, the screening helps in early identification of hearing loss, allowing for timely intervention to prevent further impairment or complications, aligning with the principles of secondary prevention.
5. Ethics committees typically do not handle which of the following issues?
- A. Nonpayment of bills.
- B. Euthanasia.
- C. Starting or stopping treatment.
- D. Use of feeding tubes.
Correct answer: A
Rationale: Ethics committees primarily focus on addressing ethical dilemmas in healthcare. Issues like euthanasia, decisions regarding starting or stopping treatment, and the use of feeding tubes for nutritional support involve complex ethical considerations related to patient care and end-of-life decisions, which are commonly deliberated by ethics committees. However, nonpayment of bills is a financial matter and falls outside the typical scope of ethics committees' functions.
