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

• A. Potassium.
• B. Calcium.
• C. Sodium.
• D. Both potassium and sodium are in equal concentrations.

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 assesses a client who had an intraosseous catheter placed in the left leg. Which assessment finding is of greatest concern?

• A. The catheter has been in place for 20 hours.
• B. . The client has poor vascular access in the upper extremities.
• C. The catheter is placed in the proximal tibia.
• D. The clients left lower extremity is cool to the touch.

Correct answer: D

Rationale:

3. Which organ has the greatest effect on fluid output?

• A. Kidneys
• B. Lungs
• C. Skin
• D. Intestines

Correct answer: A

Rationale: The correct answer is the kidneys. The kidneys are primarily responsible for regulating fluid balance by filtering blood and adjusting the volume and concentration of urine. The lungs primarily regulate gas exchange, not fluid balance. The skin plays a role in temperature regulation and protection but is not the primary organ for fluid output. The intestines are mainly involved in the absorption of nutrients and water, rather than fluid output.

4. The nurse caring for a patient post colon resection is assessing the patient on the second postoperative day. The nasogastric tube (NG) remains patent and continues at low intermittent wall suction. The IV is patent and infusing at 125 mL/hr. The patient reports pain at the incision site rated at a 3 on a 0-to-10 rating scale. During your initial shift assessment, the patient complains of cramps in her legs and a tingling sensation in her feet. Your assessment indicates decreased deep tendon reflexes (DTRs) and you suspect the patient has hypokalemia. What other sign or symptom would you expect this patient to exhibit

• A. Diarrhea
• B. Dilute urine
• C. Increased muscle tone
• D. Joint pain

Correct answer: B

Rationale:

5. A nurse is caring for a client who has a serum calcium level of 14 mg/dL. Which provider order should the nurse implement first?

• A. Encourage oral fluid intake.
• B. Connect the client to a cardiac monitor.
• C. Assess urinary output.
• D. Administer oral calcitonin (Calcimar).

Correct answer: A

Rationale: The correct answer is to encourage oral fluid intake. With a serum calcium level of 14 mg/dL, the client is at risk of hypercalcemia. Encouraging oral fluid intake helps to promote hydration and can help prevent further elevation of calcium levels. Connecting the client to a cardiac monitor (Choice B) is important but not the first priority in this situation. Assessing urinary output (Choice C) is relevant but does not address the immediate concern of high serum calcium levels. Administering oral calcitonin (Calcimar) (Choice D) may be a treatment option later, but the first step should be to address hydration.
