A nurse is caring for a client with hypertension that is prescribed metoprolol due at 0900.
The nurse took the client's blood pressure at 0855, and it was noted to be 80/60. The client also notes that he feels dizzy and weak.
What is the next intervention for the nurse?

Choice A rationale

Lactated Ringers (LR) is an isotonic solution, which means it has the same osmolarity as blood plasma. This property makes LR suitable for rehydrating patients without causing a significant shift of fluids between compartments, maintaining the balance of electrolytes.

Choice B rationale

0.45% Sodium Chloride is a hypotonic solution, meaning it has a lower osmolarity compared to blood plasma. This type of solution would cause fluid to move into cells, potentially leading to cellular swelling.

Choice C rationale

Dextrose in Lactated Ringers is a hypertonic solution because the added dextrose increases the osmolarity. This solution can cause fluid to shift out of cells, leading to cellular shrinkage, which is not ideal for rehydration.

Choice D rationale

None of the above is incorrect because Lactated Ringers (LR) is indeed an isotonic solution.

Choice A rationale

Ondansetron (Zofran) is an anti-emetic medication used to prevent nausea and vomiting by blocking serotonin receptors in the chemoreceptor trigger zone and the gastrointestinal tract.

Choice B rationale

Acetaminophen (Tylenol) is an analgesic and antipyretic medication used to relieve pain and reduce fever, but it is not an anti-emetic.

Choice C rationale

Prochlorperazine (Compazine) is an anti-psychotic and anti-emetic medication used to treat nausea and vomiting, as well as certain mental/mood disorders.

Choice D rationale

Morphine Sulfate is an opioid analgesic used to relieve moderate to severe pain but does not have anti-emetic properties.
