ATI Fluid Electrolyte and Acid-Base Regulation

1. The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?

A. Choose a hairless site if available.
B. Consider potential effects on the patients mobility when selecting a site.
C. Have the patient briefly hold his arm over his head before insertion
D. Leave the tourniquet on for at least 3 minutes.

Correct answer: B

Rationale:

2. Place a washcloth between the skin and tourniquet

A. Provide a bed bath instead of letting the client take a shower
B. Use sterile technique when changing the dressing.
C. Disconnect the intravenous fluid tubing prior to the clients bath.
D. Use a plastic bag to cover the extremity with the device

Correct answer: D

Rationale:

3. . 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:

4. A nurse is planning care for a client who is hyperventilating. The clients arterial blood gas values are pH 7.30, PaO2 94 mm Hg, PaCO2 31 mm Hg, and HCO3 26 mEq/L. Which question should the nurse ask when developing this clients plan of care?

A. Do you take any over-the-counter medications?
B. You appear anxious. What is causing your distress?
C. Do you have a history of anxiety attacks?
D. You are breathing fast. Is this causing you to feel light-headed?

Correct answer: B

Rationale:

5. The renin and angiotensin systems help to maintain the balance of sodium and water in the body. What other functions do these systems serve?

A. Regulating hemoglobin levels
B. Maintaining a healthy blood volume
C. Releasing platelets when tissues are injured
D. Lowering blood volumes

Correct answer: B

Rationale: The correct answer is B: Maintaining a healthy blood volume. The renin and angiotensin systems not only help to regulate sodium and water balance in the body but also play a crucial role in maintaining an adequate blood volume. This is essential for normal blood pressure regulation and overall cardiovascular health. Choices A, C, and D are incorrect because hemoglobin levels are primarily regulated by the bone marrow and erythropoietin, platelets are released in response to blood vessel injury by a different mechanism, and the systems do not focus on lowering blood volumes but rather on maintaining them.
