Extract:
Question 1 of 5
The nurse is caring for a client with a complete heart block. The nurse should question which of the following orders?
Correct Answer: A
Rationale: Lidocaine suppresses ventricular activity, which could worsen complete heart block by reducing the ventricular escape rhythm. Options B, C, and D are appropriate: atropine increases heart rate, pacemakers treat persistent bradycardia, and isoproterenol supports severe bradycardia.
Question 2 of 5
An adult is admitted to the emergency room with a laceration on the forearm and BP=140/74, P=110, and R=36. The client also.adult is admitted to the emergency room with a laceration on the forearm and BP=140/74, P=110, and R=36. The client also complains of tingling around the mouth and in the fingers and toes. What should the nurse expect to do initially?
Correct Answer: B
Rationale: Tachypnea and tingling suggest hyperventilation causing respiratory alkalosis; breathing into a paper bag restores CO2 levels, correcting pH.
Question 3 of 5
A client receiving HTZ (hydrochlorothiazide) is instructed to increase her dietary intake of potassium. The best snack for the client requiring increased potassium is:
Correct Answer: D
Rationale: Hydrochlorothiazide is a diuretic that can cause potassium loss. Bananas are high in potassium, making them the best choice. Pears , apples , and oranges have less potassium.
Question 4 of 5
The nurse is caring for a client who is postoperative day 1 after a gastrectomy. Which of the following findings would be of GREATest concern to the nurse?
Correct Answer: A
Rationale: A temperature of 100.8°F suggests infection, a serious complication post-gastrectomy due to risk of anastomotic leak, requiring immediate evaluation. Options B, C, and D are expected: incision pain, NG tube output, and urine output 40 mL/hour are normal on day 1.
Question 5 of 5
The nurse is caring for a client with a history of chronic obstructive pulmonary disease (COPD).
Correct Answer: B
Rationale: Chronic COPD causes CO2 retention, leading to a compensated respiratory acidosis with low pH (7.32), high PaCO2 (50 mmHg), and low PaO2 (70 mmHg) due to impaired gas exchange. Normal or acute values are incorrect.
