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

Answer and Explanation

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.

Correct Answer is B

Explanation

A. Increase in postoperative pain: Preoperative teaching typically includes information about pain management strategies, which should help to reduce, not increase, postoperative pain.

B. Reduced postoperative anxiety: This is correct. One of the key benefits of preoperative education is reduced anxiety. By understanding what to expect before, during, and after surgery, patients are often less anxious about the procedure.

C. Reduced postoperative respiratory function: Preoperative teaching usually includes instructions on deep breathing and coughing exercises to help prevent respiratory complications after surgery. Therefore, it should improve, not reduce, postoperative respiratory function.

D. Increased length of postoperative care in the health care facility: Preoperative education has been shown to reduce the length of hospital stay. By better understanding their surgery and postoperative care, patients are often able to recover more quickly and leave the hospital sooner

A. Respiratory alkalosis B. Metabolic acidosis C. Respiratory acidosis D. Metabolic alkalosis

Correct Answer is C

Explanation

Respiratory acidosis occurs when there is inadequate removal of carbon dioxide (PaCO2) by the lungs, leading to an increase in the partial pressure of carbon dioxide (hypercapnia) and a decrease in pH.

In this case, the pH is low (7.22), and the PaCO2 is elevated (68 mm Hg), indicating respiratory acidosis. The pH is below the normal range, suggesting acidemia.

The other ABG values (PaO2, oxygen saturation, and bicarbonate) are within or close to normal limits, which do not support the diagnosis of metabolic acidosis, respiratory alkalosis, or metabolic alkalosis.
