Nursing Elites

1. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

• A. A non-rebreather can provide an FiO2 of 40%.
• B. A client should breathe through his or her mouth when using a non-rebreather.
• C. A non-rebreather offers a reservoir from which the client inhales.
• D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

2. The nurse is assessing a 3-year-old child for symptoms of autism spectrum disorder (ASD). Which assessment finding should lead the nurse to question the diagnosis?

• A. Inability to react appropriately to social cues
• B. Engages in repetitive behaviors
• C. Comprehends language well beyond the complexity expected for age
• D. Displays self-destructive behavior

Correct answer: C

Rationale: The correct answer is 'Comprehends language well beyond the complexity expected for age.' Children with autism spectrum disorder typically struggle with language and communication skills, so comprehending language well beyond their age level would not align with the diagnosis of ASD. This finding could indicate other developmental strengths or delays. Choices A, B, and D are more commonly associated with ASD - the inability to react appropriately to social cues, engaging in repetitive behaviors, and displaying self-destructive behavior are typical manifestations of autism spectrum disorder.

3. The priority goal for a family who practices Chinese medicine would be to:

• A. Achieve harmony
• B. Maintain a balance of energy
• C. Respect life
• D. Restore yin and yang

Correct answer: D

Rationale: In Chinese medicine, the concept of yin and yang represents the balance of opposing forces in the body. When there is an imbalance between yin and yang, it can result in illness. Therefore, the priority goal for a family practicing Chinese medicine would be to restore the harmony and balance between yin and yang. Choices A, B, and C are not the priority goal in Chinese medicine. While achieving harmony, maintaining a balance of energy, and respecting life are important aspects of Chinese medicine, the fundamental principle revolves around maintaining the equilibrium of yin and yang for optimal health.

4. As a nursing supervisor in a long-term care facility, you prioritize strict infection control prevention measures due to the understanding that the normal aging process weakens the body's defenses. Which theory of aging supports the necessity of strict infection control prevention measures?

• A. The Programmed Longevity Theory
• B. The Immunological Theory of Aging
• C. The Endocrine Theory
• D. The Rate of Living Theory

Correct answer: B

Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.

5. Which of the following is a local sign of infection?

• A. Swelling
• B. Rapid pulse
• C. Fever
• D. High white blood count

Correct answer: A

Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.
