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?

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.

Correct Answer: D

Rationale: You should explain that fetal station is the level of the fetus's presenting part in relationship to the mother's ischial spines. Fetal station is measured in terms of the number of centimeters above or below the mother's ischial spines. When the fetus is 1 to 5 centimeters above the ischial spines, the fetal station is -1 to -5, and when the fetus is 1 to 5 centimeters below the level of the maternal ischial spines, the fetal station is +1 to +5. Choices A, B, and C provide incorrect information about fetal lie, presentation, and attitude, respectively, which do not align with the definitions of these terms in obstetrics.

Correct Answer: D

Rationale: Forming a peer workgroup to evaluate new products would be an excellent opportunity for collaboration among peers, management, and the purchasing department. When clinicians are engaged to work toward solutions that address patient care issues, they experience more empowerment and control over their work environments. Choice A is incorrect because using old stock from a previous company does not address the root cause of the faulty transducers from the current company. Choice B is incorrect as verifying cuff pressures every hour does not directly address the issue of faulty transducers. Choice C is less effective than forming a peer workgroup as it involves only notifying the risk manager without involving a collaborative effort to resolve the product issue.

Correct Answer: B

Rationale: Providing research-based information about the benefits of therapeutic hypothermia for their loved one will provide evidence that this is an established therapy with generally positive outcomes. Families are certainly not expected to be familiar with critical care interventions, and their concerns should be addressed with evidence-based data whenever possible. Option A is not appropriate as sharing patient information violates privacy laws and does not address the family's concerns directly. Option C may not directly provide the detailed information the family needs to understand therapeutic hypothermia. Option D involves unnecessary escalation by immediately involving the physician, when providing education and information should be the initial step in addressing the family's concerns.
