Question 1 of 5
A client with dilated cardiomyopathy, pulmonary edema, and severe dyspnea is placed on dobutamine. Which assessment finding indicates that the drug is effective?
Correct Answer: A
Rationale: The correct answer is A: Increased activity tolerance. Dobutamine is a positive inotrope that increases cardiac contractility, leading to improved cardiac output and oxygen delivery. As a result, the client will experience increased energy levels and improved exercise tolerance. Absence of arrhythmias (B) is important but does not directly indicate the drug's effectiveness. Negative Homans' sign (C) is unrelated to dobutamine therapy. Blood pressure of 160/90 mm Hg (D) does not specifically reflect the drug's effectiveness in this context.
Question 2 of 5
The nurse is caring for a client who has just undergone cardiac angiography. The catheter insertion site is free from bleeding or signs of hematoma. The vital signs and distal pulses remain in the client's normal range. The intravenous fluids were discontinued. The client is not hungry or thirsty and refuses any food or fluids, asking to be left alone to rest. Which of the following is the nurse's best response?
Correct Answer: A
Rationale: The correct response is A: "You are recovering well from the procedure and resting is a good idea." This is the best response because the client's vital signs, distal pulses, and catheter insertion site are stable, indicating a good recovery. Encouraging rest aligns with the client's expressed preference, which promotes comfort and healing. Choice B is incorrect as walking may not be suitable immediately post-cardiac angiography. Choice C is incorrect as forcing fluids on a client who is not thirsty can lead to discomfort. Choice D is incorrect as focusing on leg exercises may not be the priority at this immediate post-procedure stage.
Question 3 of 5
The nurse is caring for a 2-month-old child with transposition of the great vessels. Which of these interventions has highest priority?
Correct Answer: B
Rationale: The correct answer is B: Maintaining proper caloric intake. In a case of transposition of the great vessels, ensuring adequate nutrition is crucial for the infant's growth and development. Without proper caloric intake, the child may experience complications. Providing comfort for parents (choice A) is important but not the highest priority. Reducing stressors for the infant (choice C) is also important but not as critical as ensuring proper nutrition. Documenting vital signs (choice D) is necessary but does not address the immediate need for nutrition in this case.
Question 4 of 5
A nurse is monitoring a patient newly admitted with acute heart failure (HF). Which of the following laboratory/diagnostic results would indicate the presence of significant HF?
Correct Answer: A
Rationale: The correct answer is A: BNP of 1000 pg/mL. B-type natriuretic peptide (BNP) is released by the heart in response to increased ventricular wall stress, which occurs in heart failure. A BNP level of 1000 pg/mL indicates significant heart failure. Choice B: Sodium of 150 is not specific to heart failure and could indicate dehydration or other issues. Choice C: Potassium of 5.7 mEq/L is elevated but not specific to heart failure. Choice D: pH of 7.30 could indicate acidosis, but it is not a direct marker of heart failure.
Question 5 of 5
A patient has a VVIR mode pacemaker. The nurse knows that this pacemaker is characterized by which of the following?
Correct Answer: C
Rationale: The correct answer is C because in VVIR mode: 1. Ventricular pacing occurs to stimulate the ventricles. 2. Atrial sensing is present to detect the heart's natural activity. 3. Triggered response to sensing means the pacemaker responds to the heart's activity. 4. Rate modulation adjusts the pacing rate based on the body's needs. Other choices are incorrect because they either do not match the features of VVIR mode or include incorrect components like atrial pacing or ventricular sensing.
