A nurse manager is discussing social services for older adults during a staff meeting in a long- term acute care (LTAC) facility. Which statement about Medicare made by one of the employees requires correction by the nurse manager?

Medicare covers people under 65-years who have end-stage renal disease.

Low-income people who have Medicare can also qualify for Medicaid.

People who qualify for Medicare will have no out-of-pocket medical expenses.

Medicare is federally-funded health insurance for people 65-years or older.

Answer and Explanation

The Correct Answer is C

A.   Medicare does cover individuals under 65 years old who have end-stage renal disease (ESRD) and meet certain criteria.
B.   There are programs that allow individuals with both Medicare and low income to qualify for Medicaid, which can help cover additional healthcare costs that Medicare may not fully cover.
C.   While Medicare does provide significant coverage for healthcare services, it is not entirely free of out- of-pocket costs. Medicare Part A typically covers hospital stays, skilled nursing facility care, hospice, and some home health care services with no premiums for most people.
D.   Medicare is indeed federally-funded health insurance primarily for individuals aged 65 and older. It also covers certain younger individuals with disabilities and those with ESRD.

Correct Answer is C

Explanation

A. A vegetarian diet typically does not directly contribute to bronchoconstriction. In fact, a diet rich in fruits and vegetables may provide antioxidants and anti-inflammatory compounds that can be beneficial for respiratory health. Therefore, this option is less likely to be a cause of the client's bronchoconstriction.
B. Rosuvastatin (and other statins) are generally well-tolerated, but some individuals may experience respiratory side effects, including cough or shortness of breath. However, bronchoconstriction as a direct side effect of statins is uncommon and typically not a primary concern unless there is a rare hypersensitivity reaction.
C. Propranolol is a non-selective beta-blocker that can lead to bronchoconstriction, particularly in individuals with asthma or other respiratory conditions. Beta-blockers can block beta-2 receptors in the lungs, potentially causing constriction of the airways and worsening of respiratory symptoms.
D. Acetaminophen (paracetamol) is generally considered safe and does not typically cause bronchoconstriction. It is a non-steroidal anti-inflammatory drug (NSAID) that works differently from medications like beta-blockers, which directly affect the airways.

A. Maintaining specialized cell functions B. Loss of contact inhibition C. Ability to repair DNA damage D. Orderly cell cycle progression

Correct Answer is B

Explanation

A. Cancer cells typically lose their specialized functions and characteristics that normal cells have. This loss of differentiation is known as dedifferentiation, where cancer cells become less specialized and more primitive in nature. This allows them to proliferate rapidly and invade surrounding tissues.
B. Contact inhibition refers to the normal process where cells stop dividing when they come into contact with neighboring cells. In cancer cells, this mechanism is disrupted, leading to uncontrolled cell growth and proliferation. Cancer cells continue to divide and grow even when they are in close contact with other cells, which contributes to tumor formation and progression.
C. Cancer cells often acquire mutations that impair their ability to repair DNA damage effectively. This can lead to an accumulation of genetic mutations over time, which is a hallmark of cancer development. While some cancer cells may still have mechanisms to repair DNA damage, they are often less efficient compared to normal cells, leading to genomic instability and further mutation accumulation.
D. Normal cells follow a tightly regulated cell cycle with specific checkpoints that ensure orderly progression through phases such as G1, S, G2, and M phases. In contrast, cancer cells often have dysregulated cell cycle control. They may bypass checkpoints that normally control cell division, leading to uncontrolled proliferation and growth.
