A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. Requesting an order for an antiemetic may be necessary if the client continues to experience nausea, but it is not the first action the nurse should take. Before administering medication, the nurse should assess the client's vital signs and overall condition to determine the appropriate intervention.
B. While a dietitian consult may be beneficial to address the client's nutritional needs, it is not the first action the nurse should take in response to the client's symptoms of nausea and weakness. Assessing the client's vital signs and condition should be the priority.
C. Suggesting that the client rests before eating the meal may be helpful, but it does not address the underlying cause of the client's symptoms. The nurse should first assess the client's vital signs to determine the severity of the symptoms and any potential complications.
D. Checking the client's vital signs is the first action the nurse should take in response to the client's symptoms of nausea and weakness. Vital signs, including blood pressure, heart rate, respiratory rate, and temperature, can provide valuable information about the client's hemodynamic status and help identify any potential complications, such as dehydration or worsening heart failure. Based on the vital signs assessment, the nurse can then implement appropriate interventions, such as notifying the healthcare provider or providing symptomatic relief.

A. Black-colored stools: Black-colored stools are not an expected side effect of IV rifampin. Black stools can result from gastrointestinal bleeding or the consumption of certain foods or medications, but they are not directly related to rifampin administration.
B. Staining of teeth: Staining of teeth, often described as orange or red discoloration, is a well-known side effect of rifampin when taken orally. However, this side effect is typically associated with long-term oral use rather than IV administration. IV rifampin is not expected to cause staining of teeth.
C. Red-colored urine: Rifampin can cause red-orange discoloration of bodily fluids, including urine, sweat, saliva, and tears. This phenomenon is harmless and reversible but can be alarming to patients. It is important to educate clients about this potential side effect to alleviate concerns.
D. Constipation: Constipation is not a common side effect of rifampin. While gastrointestinal disturbances such as nausea, vomiting, and diarrhea can occur with rifampin therapy, constipation is not typically reported. If a client experiences persistent constipation while taking rifampin, other factors should be considered and evaluated.
