A nurse is collecting data from a client prior to administering metoprolol. For which of the following findings should the nurse withhold the medication?
Blood pressure 160/94 mm Hg
Oxygen saturation 95%
Heart rate 50/min
Respiratory rate 18/min
The Correct Answer is C
(A) Blood pressure 160/94 mm Hg:
Metoprolol is a beta-blocker commonly used to treat hypertension. A blood pressure reading of 160/94 mm Hg indicates hypertension, which is an indication for administering metoprolol, not withholding it.
(B) Oxygen saturation 95%:
An oxygen saturation of 95% is within the normal range and does not provide a reason to withhold metoprolol. Oxygen saturation levels are not directly impacted by this medication in a way that would warrant withholding it.
(C) Heart rate 50/min:
A heart rate of 50/min is bradycardia (a slow heart rate). Metoprolol can further lower the heart rate, so it should be withheld if the client is already experiencing bradycardia. The nurse should notify the healthcare provider for further instructions.
(D) Respiratory rate 18/min:
A respiratory rate of 18/min is within the normal range (12-20 breaths per minute) and does not provide a reason to withhold metoprolol. Respiratory rate is not typically a contraindication for this medication unless there are specific respiratory conditions or other related symptoms present.

Explanation
To find out how many aspirin tablets the nurse should administer, we can divide the prescribed dosage by the amount of aspirin per tablet:
Dosage m prescribed: 650 mg
Amount of aspirin per tablet: 325 mg/tablet
Number of tablets = Dosage prescribed / Amount of aspirin per tablet
Number of tablets = 650 mg / 325 mg/tablet = 2 (rounded to the nearest whole number)
Therefore, the nurse should administer 2 tablets.
Correct Answer is A
Explanation
A. "I will take my warfarin with a glass of water the night before my surgery":
This statement indicates a need for further teaching. Warfarin is an anticoagulant medication, and it should typically be discontinued or adjusted before surgery to reduce the risk of excessive bleeding. Taking it the night before surgery could increase the risk of bleeding during the procedure.
B. "I understand what risks I can expect with this surgery":
This statement suggests that the client has received information about the risks associated with the surgery, which is an essential component of preoperative education. There is no indication for further teaching based on this statement.
C. "I will take time to relax if I get nervous the night before surgery":
This statement demonstrates the client's awareness of the importance of managing stress and anxiety before surgery, which is a positive coping strategy. There is no need for further teaching based on this statement.
D. "I will have a glass of water the morning of my surgery":
This statement is generally acceptable. Clear fluids may be allowed up to a certain time before surgery, depending on the facility's protocol. However, specific instructions regarding fasting before surgery should be clarified with the healthcare provider or surgical team to ensure adherence to preoperative guidelines.
