Question 2 of 5
The health care provider (HCP) provides education to an adult client about an upcoming surgical procedure. The client states, 'I'm not clear on what is included in the low-fat diet that I'll be on after the cholecystectomy.' What action should the nurse take?
Correct Answer: C
Rationale: Providing dietary education addresses the client's question directly. Family consent is inappropriate, postponing discussion delays clarification, and procedure education doesn't address diet.
Question 3 of 5
Joan is at lunch in the hospital cafeteria with a nurse coworker. Joan is very allergic to nuts and always carries her anaphylactic kit with her. Joan tells her coworker that there must have been nuts in something she ate because she is having increasing difficulty breathing. What should the nurse do immediately?
Correct Answer: B
Rationale: Administering the anaphylactic kit medication (epinephrine) is the immediate action to reverse anaphylaxis, prioritizing airway patency.
Question 4 of 5
The client presents to the unit with complaints of shortness of breath. A tentative diagnosis of respiratory acidosis related to pneumonia is made. Which finding would support this diagnosis?
Correct Answer: B
Rationale: Respiratory acidosis is characterized by a low pH (<7.35) and elevated CO₂ (>45 mmHg) due to impaired gas exchange, as in pneumonia. Option B (pH 7.35, CO₂ 46, HCO₃ 27) is closest to this profile, with slight compensation. Options A, C, and D show normal or alkalotic pH or low CO₂.
Question 5 of 5
An elderly client is severely dehydrated. Which is the best way to assess the effectiveness of fluid restoration therapy?
Correct Answer: B
Rationale: Daily weights provide an objective measure of fluid restoration, as 1 kg approximates 1 L of fluid. Skin turgor is less reliable in elders, thirst is subjective, and intake alone doesn't confirm absorption.
