Chapter 11 Questions
Question 1 of 5
A nurse teaches clients at a community center about risks for dehydration. Which client is at greatest risk for dehydration?
Correct Answer: C
Rationale: Older adults, because they have less total body water than younger adults, are at greater risk for development of dehydration. Anyone who is cognitively impaired and cannot obtain fluids independently or cannot make his or her fluid needs known is at high risk for dehydration.
Question 2 of 5
A nurse is caring for a client who exhibits dehydration-induced confusion. Which intervention should the nurse implement first?
Correct Answer: D
Rationale: For a client with dehydration-induced confusion, the priority is to address the dehydration by increasing fluid intake to restore hydration status, which may help resolve confusion. Measuring vital signs, assessing cognitive status, or applying oxygen may be secondary actions but do not directly address the underlying cause of dehydration.
Question 3 of 5
A nurse assesses a client who is prescribed a medication that inhibits angiotensin I from converting into angiotensin II (angiotensin-converting enzyme; [ACE] inhibitor). For which expected therapeutic effect should the nurse assess?
Correct Answer: A
Rationale: ACE inhibitors will disrupt the renin-angiotensin II pathway and prevent the kidneys from reabsorbing water and sodium. The kidneys will excrete more water and sodium, decreasing the client's blood pressure.
Question 4 of 5
A nurse is assessing clients on a medical-surgical unit. Which adult client should the nurse identify as being at greatest risk for insensible water loss?
Correct Answer: A
Rationale: Insensible water loss occurs through the skin, lungs, and stool. Clients with fever and rapid respirations lose more water through increased respiratory rate and perspiration, putting them at greatest risk for insensible water loss.
Question 5 of 5
A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia?
Correct Answer: A
Rationale: Clients receiving 5% dextrose in water (D5W) contains no electrolytes. Because the client is not taking any food or fluids by mouth (NPO), normal sodium excretion can lead to hyponatremia.
