Nursing Elites

1. A home health nurse knows that a 70-year-old male client who is convalescing at home following a hip replacement is at risk for developing decubitus ulcers. Which physical characteristic of aging contributes to such a risk?

• A. 16% increase in overall body fat.
• B. Reduced melanin production.
• C. Thinning of the skin with loss of elasticity.
• D. Calcium loss in the bones.

Correct answer: C

Rationale: Thinning of the skin with loss of elasticity is the physical characteristic of aging that contributes to an increased risk of developing decubitus ulcers. As individuals age, the skin becomes thinner and loses its elasticity, making it more susceptible to damage from pressure, leading to the formation of pressure ulcers. Choices A, B, and D are incorrect as they do not directly contribute to the development of decubitus ulcers in this context.

2. You organize community groups to participate in community activities. You can BEST motivate participation in the community health development program by:

• A. Conducting group work
• B. Instructing the people to agree with your plans
• C. Allowing the people to exercise decision-making
• D. Assigning people participative roles

Correct answer: C

Rationale: Allowing people to exercise decision-making is the best way to motivate participation in community activities. By involving the community in decision-making processes, you empower them and make them feel valued, which can lead to increased engagement and commitment. Choices A, B, and D do not foster a sense of ownership and empowerment among the community members, which are crucial for sustainable participation in community programs.

3. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). The nurse should monitor the client for which of the following laboratory values?

• A. Prothrombin time (PT)
• B. Serum potassium
• C. Blood urea nitrogen (BUN)
• D. White blood cell count (WBC)

Correct answer: A

Rationale: The correct answer is A: Prothrombin time (PT). Prothrombin time is monitored to assess the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors, including factors II, VII, IX, and X. Monitoring the PT helps ensure that the client's blood is clotting within the desired therapeutic range to prevent complications such as recurrent DVT or excessive bleeding. Choices B, C, and D are incorrect because serum potassium, blood urea nitrogen, and white blood cell count are not directly related to monitoring warfarin therapy in a client with a history of DVT.

4. Which individual has the highest risk of developing community-acquired pneumonia?

• A. A 40-year-old first-grade teacher who works with underprivileged children.
• B. A 75-year-old retired secretary with exercise-induced wheezing.
• C. A 60-year-old homeless person who is an alcoholic and smokes.
• D. A 35-year-old aerobics instructor who skips meals and eats only vegetables.

Correct answer: C

Rationale: The correct answer is the 60-year-old homeless person who is an alcoholic and smokes. This individual has the highest risk of developing community-acquired pneumonia due to factors such as homelessness, alcoholism, and smoking, which weaken the immune system and make them more susceptible to respiratory infections. Choice A is incorrect as working with underprivileged children, while potentially exposing the individual to various illnesses, does not directly increase the risk of pneumonia. Choice B is less likely as exercise-induced wheezing may suggest asthma but does not directly correlate with pneumonia risk. Choice D, an aerobics instructor who eats only vegetables and skips meals, does not have the same level of risk factors for pneumonia as the homeless person in choice C.

5. When caring for premature newborns in an intensive care setting, a nurse carefully monitors oxygen concentration. What is the most common complication of this therapy?

• A. Intraventricular hemorrhage
• B. Retinopathy of prematurity
• C. Bronchopulmonary dysplasia
• D. Necrotizing enterocolitis

Correct answer: B

Rationale: Retinopathy of prematurity is the most common complication in premature infants exposed to high concentrations of oxygen. This condition leads to abnormal blood vessel growth in the retina, which can potentially result in blindness if not managed promptly. Intraventricular hemorrhage, though a significant concern in premature infants, is not directly related to oxygen therapy. Bronchopulmonary dysplasia is primarily associated with mechanical ventilation and oxygen exposure over time, not specifically with oxygen concentration monitoring. Necrotizing enterocolitis is more linked to gastrointestinal issues and is not the most common complication of oxygen therapy in premature newborns.
