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. Battery involves the unauthorized or harmful touching of another person without their consent. Restraint without proper justification could potentially lead to a charge of battery, but the situation described does not involve actual physical contact.
B. Assault involves the threat of bodily harm to another person, creating fear or apprehension that the harm will be carried out. While the threat of restraint might cause fear, actual restraint is necessary to constitute assault.
C. Invasion of privacy refers to the unauthorized intrusion into an individual's private affairs or the public disclosure of private information. It does not apply to the act of physically restraining a client.
D. False imprisonment occurs when an individual is unlawfully restrained or confined against their will. In this scenario, the provider's directive to restrain the client against her wishes constitutes false imprisonment if the restraint is not justified by the client's medical condition or pose an immediate danger to herself or others.
Correct Answer is C
Explanation
A. Take the medication with dairy products to increase absorption: Calcium carbonate antacids should not be taken with dairy products as they can reduce the absorption of calcium due to the formation of insoluble calcium salts. It's recommended to take calcium carbonate antacids between meals or with a light snack, but not with dairy products.
B. Decrease bulk in the diet to counteract the adverse effect of diarrhea: Calcium carbonate antacids can sometimes cause constipation rather than diarrhea. Increasing dietary fiber and fluid intake may help prevent constipation associated with the use of these antacids. Therefore, advising to decrease bulk in the diet is not appropriate.
C. Draw a glass of water after taking the medication: Calcium carbonate antacids should be taken with a full glass of water to ensure proper dissolution in the stomach and to prevent the risk of gastrointestinal irritation or obstruction. Water helps facilitate the dissolution and absorption of the medication, reducing the risk of adverse effects.
D. Reduce sodium intake: Calcium carbonate antacids may contain sodium, but reducing sodium intake is not a specific recommendation related to taking this medication. However, it's generally advisable to limit sodium intake for overall health, especially for individuals with conditions such as hypertension or heart failure.
