A nurse is assessing a client prior to administering atenolol. Which of the following findings should prompt the nurse to withhold the medication?
Correct answer
D
Rationale
The correct answer is D: Heart rate 46/min. Atenolol is a beta-blocker that slows down heart rate. A heart rate of 46/min indicates bradycardia, which is a contraindication for administering atenolol. Oxygen saturation of 95% (A) is within normal range, respiratory rate of 18/min (B) is also normal, and blood pressure of 160/94 mm Hg (C) may be high but not a reason to withhold atenolol. In summary, bradycardia is the key factor in withholding atenolol, as it can further decrease heart rate and lead to adverse effects.
