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 C

Explanation

A. Dry skin:

Dry skin is not typically associated with respiratory alkalosis. Instead, it may occur in conditions such as dehydration or impaired skin integrity.

B. Diarrhea:

Diarrhea is not typically associated with respiratory alkalosis. Respiratory alkalosis primarily involves changes in the respiratory system, leading to alterations in blood pH and carbon dioxide levels.

C. Hyperventilation:

Hyperventilation is a characteristic finding in respiratory alkalosis. It is a compensatory mechanism where the client breathes rapidly and deeply to blow off excess carbon dioxide, attempting to restore acid-base balance.

D. Abdominal pain:

Abdominal pain is not typically associated with respiratory alkalosis. While some individuals with respiratory alkalosis may experience symptoms such as dizziness, lightheadedness, or tingling sensations, abdominal pain is not a common manifestation of this acid-base imbalance.

A. "This medication will help maintain a normal heart rhythm." B. "Warfarin helps prevent strokes in clients who have atrial fibrillation." C. "Warfarin dissolves clots in the bloodstream." D. This medication slows the response of the ventricles to the fast atrial impulses."

Correct Answer is B

Explanation

A. "This medication will help maintain a normal heart rhythm":

Warfarin is not typically used to maintain a normal heart rhythm in atrial fibrillation. It is primarily used for stroke prevention by anticoagulation.

B. "Warfarin helps prevent strokes in clients who have atrial fibrillation":

This statement is accurate. Warfarin is an anticoagulant medication that is commonly prescribed for clients with atrial fibrillation to reduce the risk of stroke by preventing blood clots from forming in the heart and traveling to the brain.

C. "Warfarin dissolves clots in the bloodstream":

Warfarin does not directly dissolve clots in the bloodstream. It works by inhibiting the production of clotting factors in the liver, thereby preventing the formation of new clots and reducing the risk of clot-related complications such as stroke.

D. "This medication slows the response of the ventricles to the fast atrial impulses":

This statement refers more to medications used for rate control in atrial fibrillation rather than warfarin. Warfarin does not directly affect the heart rate or the response of the ventricles to atrial impulses.
