1. A nurse assesses a client who is prescribed a medication that inhibits aldosterone secretion and release. For which potential complications should the nurse assess? (Select all that apply.)

A. Urine output of 25 mL/hr
B. Serum potassium level of 5.4 mEq/L
C. Blood osmolality of 250 mOsm/L
D.

Correct answer: A

Rationale:

2. . 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:

3. While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?

A. Grade 3 phlebitis at IV site
B. infection at IV site
C. Thrombosed area at IV site
D. infiltration at IV site

Correct answer: A

Rationale:

4. What happens first in dehydration?

A. Intercellular fluid volume drops first.
B. Plasma volume drops first.
C. Interstitial fluid drops first.
D. Neither interstitial nor intracellular fluid volume are affected.

Correct answer: C

Rationale: In dehydration, the body first draws fluid from the interstitial space to maintain blood volume, leading to a decrease in interstitial fluid volume. This is why choice C is correct. Choice A is incorrect because intracellular fluid is not the first to be affected. Choice B is also incorrect as plasma volume reduction typically occurs after interstitial fluid loss. Choice D is incorrect as dehydration impacts both interstitial and intracellular fluid volumes.
