ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?

A. Administer topical lidocaine to the site.
B. Place warm compresses on the site.
C. . Administer prescribed oral pain medication.
D. Massage the site with scented oils.

Correct answer: B

Rationale:

2. A nurse is assessing a client who has an electrolyte imbalance related to renal failure. For which potential complications of this electrolyte imbalance should the nurse assess? (Select all that do mot apply.)

A. Electrocardiogram changes
B. Slow, shallow respirations
C. Paralytic ileus
D. Skeletal muscle weakness

Correct answer: B

Rationale:

3. A nurse in the neurologic ICU has orders to infuse a hypertonic solution into a patient with increased intracranial pressure. This solution will increase the number of dissolved particles in the patients blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. This process is best described as which of the following?

A. Hydrostatic pressure
B. Osmosis and osmolality
C. Diffusion
D. Active transport

Correct answer: B

Rationale:

4. . A 73-year-old man comes into the emergency department (ED) by ambulance after slipping on a small carpet in his home. The patient fell on his hip with a resultant fracture. He is alert and oriented; his pupils are equal and reactive to light and accommodation. His heart rate is elevated, he is anxious and thirsty, a Foley catheter is placed, and 40 mL of urine is present. What is the nurses most likely explanation for the low urine output?

A. The man urinated prior to his arrival to the ED and will probably not need to have the Foley catheter kept in place.
B. The man likely has a traumatic brain injury, lacks antidiuretic hormone (ADH), and needs vasopressin.
C. The man is experiencing symptoms of heart failure and is releasing atrial natriuretic peptide that results in decreased urine output.
D. The man is having a sympathetic reaction, which has stimulated the reninangiotensinaldosterone system that results in diminished urine output.

Correct answer: D

Rationale:

5. You are performing an admission assessment on an older adult patient newly admitted for end-stage liver disease. What principle should guide your assessment of the patient's skin turgor?

A. Overhydration is common among healthy older adults.
B. Dehydration causes the skin to appear spongy.
C. Inelastic skin turgor is a normal part of aging.
D. Skin turgor cannot be assessed in patients over 70.

Correct answer: C

Rationale: Inelastic skin is a normal change of aging. However, this does not mean that skin turgor cannot be assessed in older patients. Dehydration, not overhydration, causes inelastic skin with tenting. Overhydration, not dehydration, causes the skin to appear edematous and spongy. Choice A is incorrect because overhydration is not common among healthy older adults. Choice B is incorrect because dehydration leads to inelastic skin, not sponginess. Choice D is incorrect as skin turgor assessment can be done in patients of any age, including those over 70.
