Nursing Elites

1. . One day after a patient is admitted to the medical unit, you note that the patient is oliguric. You notify the acutecare nurse practitioner who orders a fluid challenge of 200 mL of normal saline solution over 15 minutes. This intervention will achieve which of the following?

• A. Help distinguish hyponatremia from hypernatremia
• B. Help evaluate pituitary gland function
• C. Help distinguish reduced renal blood flow from decreased renal function
• D. Help provide an effective treatment for hypertension-induced oliguria

Correct answer: C

Rationale:

2. Where is the largest volume of water in the body located?

• A. Plasma
• B. The fluid inside the cells
• C. Interstitial fluid
• D. Lymph

Correct answer: B

Rationale: The correct answer is B. The largest volume of water in the body is found inside the cells, known as intracellular fluid. This fluid makes up the majority of the body's total water content. Choices A, C, and D are incorrect because while plasma, interstitial fluid, and lymph are important components of the body's fluid compartments, they do not contain the largest volume of water in the body.

3. Which negative ion is most abundant in blood plasma?

• A. Bicarbonate
• B. Chloride
• C. Hydroxide
• D. Phosphate

Correct answer: B

Rationale: Chloride (Cl-) is the most abundant anion in blood plasma. It plays a crucial role in maintaining osmotic balance and acid-base homeostasis. Bicarbonate (Choice A) is important for buffering acids in the body but is not the most abundant negative ion in blood plasma. Hydroxide (Choice C) is not typically found in high concentrations in blood plasma. Phosphate (Choice D) is an important anion in the body but is not as abundant as chloride in blood plasma.
