ATI Fluid and Electrolytes

1. What is the most abundant positive ion in blood plasma?

Correct answer: C

Rationale: The correct answer is C: Sodium. Sodium (Na+) is the most abundant cation in the extracellular fluid, including blood plasma. It plays a crucial role in maintaining fluid balance, nerve function, and is essential for various physiological processes. Choice A, Potassium, is also an important ion in the body but is predominantly found intracellularly. Choice B, Calcium, is an essential mineral in the body but is not the most abundant positive ion in blood plasma. Choice D is incorrect as sodium is the primary positive ion in blood plasma, with a much higher concentration compared to potassium.

2. A nurse is assessing a client who has an electrolyte imbalance related to renal failure. For which potential complications of this electrolyte imbalance should the nurse assess? (Select all that do mot apply.)

Correct answer: B

Rationale:

3. You are performing an admission assessment on an older adult patient newly admitted for end-stage liver disease. What principle should guide your assessment of the patient's skin turgor?

Correct answer: C

Rationale: Inelastic skin is a normal change of aging. However, this does not mean that skin turgor cannot be assessed in older patients. Dehydration, not overhydration, causes inelastic skin with tenting. Overhydration, not dehydration, causes the skin to appear edematous and spongy. Choice A is incorrect because overhydration is not common among healthy older adults. Choice B is incorrect because dehydration leads to inelastic skin, not sponginess. Choice D is incorrect as skin turgor assessment can be done in patients of any age, including those over 70.

4. A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation, which can be caused by extreme anxiety, is the most common cause of acute respiratory alkalosis. This leads to a decrease in PaCO2 levels. Respiratory acidosis, choice A, occurs in conditions like hypoventilation, leading to an increase in PaCO2 levels. Choice C, Increased PaCO2, is not the correct term for an acid-base imbalance related to hyperventilation. Choice D, CNS disturbances, is not directly related to the acid-base imbalance caused by hyperventilation.

5. A medical-surgical nurse is concerned about the incidence of complications related to IV therapy, including bloodstream infection. Which intervention should the nurse suggest to the management team to make the biggest impact on decreasing complications

Correct answer: A

Rationale:
