1. A nurse is assessing clients who have intravenous therapy prescribed. Which assessment finding for a client with a peripherally inserted central catheter (PICC) requires immediate attention?

A. The initial site dressing is 3 days old.
B. The PICC was inserted 4 weeks ago.
C. A securement device is absent.
D. Upper extremity swelling is noted.

Correct answer: D

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. A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause

A. Respiratory acidosis
B. Respiratory alkalosis
C. Increased PaCO2
D. CNS disturbances

Correct answer: B

Rationale:

4. 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.

5. What is the fluid inside the cell called?

A. Plasma
B. Intracellular fluid
C. Interstitial fluid
D. Plasma and intracellular fluid

Correct answer: B

Rationale: The correct answer is 'Intracellular fluid.' Intracellular fluid refers to the fluid contained within the cells, constituting a significant portion of the body's total water content. Choices A, C, and D are incorrect. Plasma is the liquid component of blood outside the cells, interstitial fluid is the fluid surrounding cells in tissues, and the combination of plasma and intracellular fluid is not the specific term for the fluid inside the cell.
