Nursing Elites

1. Which of the following components is associated with hypertonic dehydration?

• A. Plasma sodium levels above 150 mEq/L
• B. Fluid moves from extracellular space to intracellular space
• C. Water loss is greater than electrolyte loss
• D. Physical signs and symptoms are grossly apparent

Correct answer: C

Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.

2. Asepsis is defined as ________________.

• A. the absence of all microorganisms
• B. the absence of disease-causing germs
• C. a urinary infection
• D. a pathogenic infection

Correct answer: B

Rationale: Asepsis is defined as the absence of disease-causing germs. It is surgical asepsis that is defined as the absence of all microorganisms, including spores. A pathogenic infection is an invasion of the body by a pathogen, or disease-causing germ, and a urinary infection is only one type of infection.

3. 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.

4. A toddler has recently been diagnosed with cerebral palsy. Which of the following information should the nurse provide to the parents? Select one that doesn't apply.

• A. Regular developmental screening is important to avoid secondary developmental delays.
• B. Cerebral palsy is caused by injury to the upper motor neurons and results in motor dysfunction, as well as possible ocular and speech difficulties.
• C. Developmental milestones may be slightly delayed but usually will require no additional intervention.
• D. Parent support groups are helpful for sharing strategies and managing health care issues.

Correct answer: C

Rationale: The correct answer is 'Developmental milestones may be slightly delayed but usually will require no additional intervention.' This statement is incorrect as delayed developmental milestones in a child with cerebral palsy require interventions and constant follow-ups. Developmental monitoring is essential to track a child's growth and development over time. If any concerns are raised during monitoring, a developmental screening test should be conducted promptly to address any developmental delays or issues. Regular interventions, therapies, and support are crucial to optimize the child's development and well-being. Therefore, it is important for parents to be aware that additional interventions may be necessary to support their child's development.

5. Research participants are involved in a trial that incidentally separates them into two groups. One group receives an intervention, while the other group does not. Both groups are compared for outcomes. What type of research method is this?

• A. Experimental design
• B. Double-blind experiment
• C. Randomized controlled trial
• D. Repeated measures design

Correct answer: C

Rationale: A randomized controlled trial is a research method in which participants are randomly assigned to either a treatment or control group. This design helps eliminate bias and allows for the comparison of outcomes between the two groups. In this scenario, where participants are separated into intervention and non-intervention groups for comparison, it aligns with the characteristics of a randomized controlled trial. The key feature distinguishing it from the other options is the random assignment of participants to groups, ensuring that both groups are comparable at the start of the study. Double-blind experiments involve blinding both participants and researchers to treatment allocation, which is not explicitly mentioned in the scenario. Experimental design refers to a broader category that includes various types of research designs beyond just randomized controlled trials. Repeated measures design involves collecting multiple observations from the same participants over time, which is not the case described in the scenario.
