ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for clients with electrolyte imbalances on a medical-surgical unit. Which clinical manifestations are correctly paired with the contributing electrolyte imbalance? (Select all that do not apply.)

Correct answer: B

Rationale:

2. A home care nurse prepares to administer intravenous medication to a client. The nurse assesses the site and reviews the clients chart prior to administering the medication: Client: Thomas Jackson DOB: 5/3/1936 Gender: Male January 23 (Today): Right uppe

Correct answer: B

Rationale:

3. When selecting a site on the hand or arm for insertion of an IV catheter, the nurse should:

Correct answer: B

Rationale: When selecting a site for insertion of an IV catheter, the nurse should choose a distal site, not a proximal site. Opting for a distal site ensures that upper veins remain available for future cannulations. Instructing the patient to hold their arm in a dependent position can enhance blood flow, aiding in the procedure. It is crucial never to leave a tourniquet on for more than 2 minutes as prolonged restriction can lead to complications. Choice A is incorrect because a proximal site is not preferred for IV insertion. Choice C is incorrect as having the patient hold their arm over their head is not necessary and may impede proper blood flow. Choice D is incorrect as leaving the tourniquet on for at least 5 minutes is excessive and can be harmful.

4. 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.

5. A nurse is caring for a client who is experiencing excessive diarrhea. The clients arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3 16 mEq/L. Which provider order should the nurse expect to receive?

Correct answer: B
