ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse teaches a client who is prescribed a central vascular access device. Which statement should the nurse include in this clients teaching?

A. You will need to wear a sling on your arm while the device is in place
B. There is no risk of infection because sterile technique will be used during insertion.
C. . Ask all providers to vigorously clean the connections prior to accessing the device.
D. You will not be able to take a bath with this vascular access device.

Correct answer: C

Rationale:

2. 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.

3. A nurse assesses a client who is admitted for treatment of fluid overload. Which manifestations should the nurse expect to find? (Select all that do not apply.)

A. Increased pulse rate
B. . Distended neck veins
C. Warm and pink skin
D. Skeletal muscle weakness

Correct answer: C

Rationale:

4. Which of the following is not considered an extracellular fluid?

A. Cerebrospinal fluid
B. The humors of the eye
C. Lymph
D. Cerebrospinal fluid and the humors of the eye

Correct answer: D

Rationale: The correct answer is D. Cerebrospinal fluid and the humors of the eye are not considered extracellular fluids. Extracellular fluids are fluids found outside the cells, such as interstitial fluid and lymph. Cerebrospinal fluid is found within the central nervous system, while the humors of the eye (aqueous humor and vitreous humor) are located within the eyeball, making them distinct from extracellular fluids.

5. A nurse is taking care of a 65-year-old female patient in a medical-surgical unit who is in renal failure; during the assessment, the patient complains of tingling in her lips and fingers. When the nurse takes her blood pressure, she has a spasm in her wrist and hand. The nurse suspects:

A. Hypophosphatemia
B. Hypocalcemia
C. Hypermagnesemia
D. Hyperkalemia

Correct answer: B

Rationale: The patient's symptoms of tingling in the lips and fingers along with the wrist and hand spasm are indicative of tetany, a characteristic manifestation of hypocalcemia. Hypocalcemia and hypomagnesemia can present with sensations of tingling in the extremities and around the mouth. The spasm in the wrist and hand when taking blood pressure could be due to slight ischemia of the ulnar nerve, further supporting the suspicion of hypocalcemia in this patient. Hypophosphatemia, hypermagnesemia, and hyperkalemia do not typically present with these specific symptoms and manifestations.
