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.)
The Correct Answer is ["0.5"]
Let's convert the digoxin dosage from mcg (micrograms) to mg (milligrams) and then divide it by the amount of digoxin per tablet to find out how many tablets are needed.
Steps to solve:
- Convert digoxin dose from mcg to mg:
- We know 1 mg is equal to 1000 mcg.
- Digoxin dose (mg) = Digoxin dose (mcg) / 1000 mcg/mg
- Digoxin dose (mg) = 125 mcg / 1000 mcg/mg
- Digoxin dose (mg) = 0.125 mg
- Calculate the number of tablets required:
- Number of tablets = Digoxin dose (mg) / Digoxin per tablet (mg)
- Number of tablets = 0.125 mg / 0.25 mg/tablet
Since the result is 0.5, we need to round to the nearest tenth.
Answer: The nurse should administer 0.5 tablets per dose.

Correct Answer is D
Explanation
A. Take the medication with meals: Beclomethasone is an inhaled corticosteroid used to prevent asthma symptoms. It should be taken as prescribed by the healthcare provider, usually inhaled at specific times each day. Taking the medication with meals is not necessary, as it does not affect its efficacy or absorption.
B. Check the pulse after medication administration: Checking the pulse is not typically indicated after administering inhaled beclomethasone. Beclomethasone is a corticosteroid inhaler used for long-term control of asthma symptoms and is not associated with significant cardiovascular effects that would necessitate pulse monitoring.
C. Limit caffeine intake: Limiting caffeine intake is not specifically related to the administration of inhaled beclomethasone. However, caffeine can exacerbate some asthma symptoms in susceptible individuals, so general advice to limit caffeine intake may be beneficial for managing asthma symptoms overall. Still, it's not directly related to the administration of this medication.
D. Rinse the mouth after administration: This is the correct action. Inhaled corticosteroids like beclomethasone can cause local side effects such as oral candidiasis (thrush) or dysphonia (hoarseness) due to deposition of the medication in the mouth and throat. Rinsing the mouth with water after each dose helps minimize these side effects by reducing the amount of medication left in the mouth, thereby decreasing the risk of oral candidiasis and other local adverse effects.
Correct Answer is C
Explanation
A. Asking the client if they have talked to their parents about their anxiety may not be appropriate, as it assumes the client is comfortable discussing their concerns with their parents. It's important to establish rapport and trust with the client before delving into personal matters such as family dynamics.
B. Asking "Why do you think you are so anxious?" may come across as confrontational and put the client on the defensive. It's important to approach the client's concerns with empathy and understanding rather than seeking an explanation for their anxiety.
C. This response acknowledges the client's feelings and validates their experience, showing empathy and understanding. It opens the door for further exploration of the client's concerns and allows the nurse to provide support and assistance.
D. While assessing the duration of symptoms is important, asking "How long has this been going on?" as an initial response may feel dismissive to the client's current distress. Starting with an empathetic acknowledgment of the client's experience can help build rapport and trust before delving into more specific questions about the duration and severity of symptoms.
