Question 1 of 5
The nurse is caring for a client with atrial fibrillation who is being treated with a variety of drugs. The nurse administers which of the following drugs in combination with quinidine that may result in an increased level of the drug?
Correct Answer: B
Rationale: Quinidine with digoxin (B) can double digoxin levels due to reduced clearance, risking toxicity. Others (A, C, D) don’t have this interaction.
Question 2 of 5
Which type of blood cell is involved in the clotting mechanism of blood?
Correct Answer: D
Rationale: Platelets (thrombocytes) are critical for blood clotting, aggregating at injury sites and releasing clotting factors. Neutrophils and eosinophils fight infection, and lymphocytes are immune cells, not directly involved in clotting.
Question 3 of 5
A client with atrial fibrillation is receiving digoxin (Lanoxin). It is MOST important for the nurse to?
Correct Answer: A
Rationale: Digoxin slows heart rate in atrial fibrillation; measuring the apical pulse before administration ensures it’s not below 60 bpm, preventing bradycardia toxicity. Other actions are useful but secondary to this safety priority.
Question 4 of 5
The nurse auscultates bibasilar inspiratory crackles in a newly admitted 68 year-old client with a diagnosis of congestive heart disease. Which of the following symptoms is MOST likely to occur?
Correct Answer: B
Rationale: Bibasilar crackles indicate pulmonary edema from left-sided congestive heart failure, often accompanied by peripheral edema due to fluid retention from right heart failure. Chest pain is less specific, and clubbing is linked to chronic hypoxia, not acute CHF.
Question 5 of 5
A patient is admitted to the hospital for a carotid angiogram with stent placement. The patient's spouse states, 'I don’t want my spouse to find out there is a risk of a stroke connected with this procedure because they won’t sign the consent form.' The cardiac-vascular nurse’s most appropriate action is to:
Correct Answer: A
Rationale: The nurse must ensure the patient’s informed consent by assessing their understanding of risks (e.g., stroke), benefits, and alternatives, respecting autonomy. B misleads, C avoids full disclosure, and D is procedural, not ethical.
