ATI Fluid Electrolyte and Acid-Base Regulation
1. A client with a serum potassium of 7.5 mEq/L and cardiovascular changes needs immediate intervention. Which prescription should the nurse implement first?
- A. Prepare to administer sodium polystyrene sulfate (Kayexalate) 15 g by mouth.
- B. Provide a heart-healthy, low-potassium diet.
- C. Prepare to administer dextrose 20% and 10 units of regular insulin IV push.
- D. Prepare the client for hemodialysis treatment.
Correct answer: Prepare to administer dextrose 20% and 10 units of regular insulin IV push.
Rationale: In a client with a serum potassium level of 7.5 mEq/L and cardiovascular changes, the priority intervention is to lower the potassium level quickly to prevent life-threatening complications like arrhythmias. The correct answer is to prepare to administer dextrose 20% and 10 units of regular insulin IV push. This combination helps shift potassium from the extracellular to the intracellular space, reducing serum potassium levels rapidly. Administering sodium polystyrene sulfate (Kayexalate) by mouth may take several hours to work, making it a less effective immediate intervention. Providing a heart-healthy, low-potassium diet is important for long-term management but is not the most urgent action in this situation. While hemodialysis is a definitive treatment for hyperkalemia, it is not the first-line intervention for acute management of high potassium levels with cardiovascular manifestations.
2. What is the main concern with collective bargaining?
- A. Create tension among nurses.
- B. Reform health care.
- C. Secure economic security.
- D. Unite the nurses.
Correct answer: A
Rationale: The main concern with collective bargaining is that it can create tension among nurses. The bargaining process may lead to divisions between staff nurses and management, rather than uniting them. This tension can arise from differing priorities, goals, or interests between the two groups, potentially impacting the effectiveness of the bargaining process. Choices B, C, and D are incorrect because the primary focus of the concern is on the potential negative impact on nurse relationships, not on reforming healthcare, ensuring economic security, or uniting nurses.
3. Which should the nurse teach to parents regarding oral health of children? (Select all that apply.)
- A. Fluoridated water should be used.
- B. Early childhood caries is a preventable disease
- C. All options are correct
- D. Dental hygiene should begin with the first tooth eruption
Correct answer: C
Rationale: Fluoridated water helps prevent caries, early childhood caries is preventable, and dental hygiene should start with the first tooth eruption.
4. A client with heart failure is prescribed digoxin. Which of the following findings should the nurse identify as an adverse effect of digoxin?
- A. Constipation
- B. Blurred vision
- C. Nausea
- D. Headache
Correct answer: B
Rationale: Blurred vision is a common adverse effect of digoxin and can indicate toxicity. Monitoring for visual changes is essential to prevent serious complications in clients taking digoxin.
5. How does genetic predisposition influence mental health?
- A. Genetic predisposition guarantees the development of mental disorders.
- B. Genetic predisposition plays a role but is not the sole determinant of mental health.
- C. Genetic predisposition does not influence mental health.
- D. Genetic predisposition determines mental health without exception.
Correct answer: B
Rationale: Genetic predisposition indeed plays a significant role in influencing mental health by increasing the risk of developing certain disorders. However, it is crucial to note that it is not the sole determinant. Mental health is also influenced by various environmental factors, lifestyle choices, and individual experiences. Option A is incorrect because genetic predisposition does not guarantee the development of mental disorders; it only predisposes individuals to a higher risk. Option C is incorrect as genetic predisposition does have an influence on mental health. Option D is incorrect because mental health is a complex interplay of genetic, environmental, and other factors.
