Nursing Elites

1. What fluid is found in spaces between the cells?

• A. Intracellular fluid
• B. Interstitial fluid
• C. Plasma
• D. Electrolyte

Correct answer: B

Rationale: The correct answer is B, Interstitial fluid. Interstitial fluid is the fluid that surrounds and occupies the spaces between cells, providing them with nutrients and removing waste. Choices A, C, and D are incorrect because intracellular fluid refers to fluid inside cells, plasma refers to the liquid component of blood, and electrolyte refers to substances that dissociate into ions in solution, affecting fluid balance but not specifically found in spaces between cells.

2. What percentage of body water can be as high as in a newborn?

• A. 80%.
• B. 70%.
• C. 60%.
• D. 90%.

Correct answer: A

Rationale: The correct answer is A: 80%. Newborns can have a body water content as high as 80% due to their higher total body water compared to adults. Choice B (70%) is incorrect because newborns typically have a higher body water percentage. Choice C (60%) is also incorrect as it underestimates the body water content in newborns. Choice D (90%) is incorrect as it overestimates the body water percentage in newborns.

3. Retention of electrolytes (especially sodium) in the interstitial fluid can result from:

• A. decreased aldosterone secretion.
• B. increased ADH secretion.
• C. increased aldosterone secretion.
• D. decreased ADH secretion.

Correct answer: C

Rationale: The correct answer is C: increased aldosterone secretion. Aldosterone, a hormone produced by the adrenal glands, increases sodium reabsorption in the kidneys, leading to retention of sodium and water in the interstitial fluid. Increased aldosterone secretion enhances the reabsorption of sodium, thereby increasing its retention. Choice A is incorrect because decreased aldosterone secretion would lead to less sodium reabsorption and increased excretion. Choice B is incorrect because increased ADH secretion primarily affects water reabsorption rather than sodium. Choice D is incorrect because decreased ADH secretion would lead to increased water excretion but not necessarily affect sodium retention.

4. Which substance dissociates into ions in a water solution?

• A. Intracellular fluid
• B. Interstitial fluid
• C. Plasma
• D. Electrolyte

Correct answer: D

Rationale: The correct answer is 'Electrolyte.' Electrolytes are substances that dissociate into ions when dissolved in water. Intracellular fluid, interstitial fluid, and plasma are not substances that dissociate into ions in a water solution. Intracellular fluid is the fluid inside cells, interstitial fluid is the fluid between cells, and plasma is the liquid component of blood. These choices do not dissociate into ions in a water solution, unlike electrolytes.

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

• A. Initiate a dedicated team to insert access devices
• B. . Require additional education for all nurses.
• C. Limit the use of peripheral venous access devices.
• D. Perform quality control testing on skin preparation products.

Correct answer: A
