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. pH 7.48:
A pH of 7.48 indicates alkalosis, not acidosis. Respiratory acidosis is characterized by a pH below the normal range (7.35-7.45).
B. pH 7.50:
Similar to choice A, a pH of 7.50 indicates alkalosis, not acidosis.
C. pH 7.31:
This pH value falls below the normal range (7.35-7.45), indicating acidemia. In respiratory acidosis, there is an increase in the partial pressure of carbon dioxide (PaCO2) in the blood, leading to an accumulation of carbonic acid and a decrease in pH.
D. pH 7.39:
A pH of 7.39 falls within the normal range (7.35-7.45), indicating a normal acid-base balance. It does not indicate acidosis.
Correct Answer is D
Explanation
A. Have the client place their head between their knees:
Placing the head between the knees may help alleviate symptoms of hyperventilation by promoting relaxation and reducing dizziness. This position can help increase venous return to the heart and improve cerebral blood flow, which may reduce symptoms associated with hyperventilation.
B. Plan to administer sodium bicarbonate to the client:
Sodium bicarbonate is not indicated for respiratory alkalosis. It is used to treat metabolic acidosis by increasing plasma bicarbonate levels. Administering sodium bicarbonate to a client with respiratory alkalosis may exacerbate the alkalosis by further increasing the pH of the blood.
C. Plan to administer insulin to the client:
Insulin administration is not indicated for respiratory alkalosis. Insulin is used to manage hyperglycemia in diabetes mellitus and does not address the underlying respiratory condition causing alkalosis.
D. Have the client breathe into a paper bag:
Breathing into a paper bag is a common intervention for managing hyperventilation associated with respiratory alkalosis. Rebreathing exhaled carbon dioxide helps increase carbon dioxide levels in the blood, which can reverse the alkalosis and alleviate symptoms of hyperventilation.
