A nurse is caring for a client who has a prescription for metoprolol. The nurse measures the client's vital signs and notes that the client's apical heart rate is 49/min. The nurse should prepare to administer which of the following medications?
Diltiazem
Atropine
Digoxin
Carvedilol
The Correct Answer is B
A. Diltiazem: Diltiazem is a calcium channel blocker used to treat high blood pressure and heart rhythm disorders. However, it can further lower the heart rate, which is not desirable in this case as the client’s heart rate is already low.
B. Atropine: This is correct. Atropine is often used to treat bradycardia (low heart rate). It works by blocking the action of the vagus nerve on the heart, which increases the heart rate.
C. Digoxin: Digoxin is used to treat heart failure and atrial fibrillation1. However, one of its side effects is that it can lower the heart rate, so it would not be appropriate to give to a client who already has a low heart rate.
D. Carvedilol: Carvedilol is a beta-blocker used to treat high blood pressure and heart failure1. Like other beta-blockers, it can lower the heart rate, so it would not be appropriate to give to a client who already has a low heart rate.

Correct Answer is C
Explanation
A. Cerebral edema:
Cerebral edema is not typically associated with hyperkalemia. It is more commonly seen in conditions such as hyponatremia or cerebral trauma.
B. Hypoactive bowel sounds:
Hypoactive bowel sounds are not typically associated with hyperkalemia. They may occur in conditions such as paralytic ileus or intestinal obstruction.
C. Decreased deep tendon reflexes:
Decreased deep tendon reflexes (hyporeflexia) are a common manifestation of hyperkalemia. High potassium levels can impair neuromuscular function, leading to decreased reflexes.
D. Wheezing:
Wheezing is not typically associated with hyperkalemia. It may occur in conditions such as asthma or chronic obstructive pulmonary disease (COPD).
Correct Answer is A
Explanation
A. Check the client's distal pulses in both legs:
Checking the client's distal pulses in both legs is crucial to ensure that there is adequate blood flow and no signs of arterial occlusion or complications from the catheterization. This is an important assessment to detect potential vascular complications, such as a hematoma or an arterial blockage.
B. Keep the client overnight:
Keeping the client overnight is not typically required for all cardiac catheterization procedures. The need for an overnight stay depends on the individual case and any complications or comorbidities. Routine catheterizations often allow for discharge on the same day with appropriate monitoring.
C. Keep the client on bed rest for 12 hr:
Keeping the client on bed rest for 12 hours is excessive. Typically, bed rest is required for 2 to 6 hours following the procedure to allow the puncture site to stabilize and reduce the risk of bleeding. The exact duration of bed rest depends on the approach used and the patient's condition.
D. Restrict the client's oral fluids:
Restricting the client's oral fluids is generally not appropriate. In fact, increasing fluid intake is often encouraged to help flush out the contrast dye used during the procedure and to prevent renal complications. Monitoring for fluid balance is important, but outright restriction is not typically indicated unless there is a specific medical reason.
