Order, digoxin (Lanoxin) 0.25 mg IM daily. Available digoxin (Lanoxin) 0.5 mg/2 mL How many mL will the nurse administer?
The Correct Answer is ["1"]
To calculate the amount of mL the nurse should administer, we can use a proportion based on the available concentration of digoxin (Lanoxin) and the prescribed dose.
The available concentration is 0.5 mg/2 mL, which means there are 0.5 mg of digoxin in 2 mL of solution.
The prescribed dose is 0.25 mg.
Now we can set up the proportion:
0.5 mg / 2 mL = 0.25 mg / x mL
Cross-multiplying, we have:
0.5 mg * x mL = 2 mL * 0.25 mg
0.5x = 0.5
Dividing both sides by 0.5, we get:
x = 0.5 / 0.5
x = 1
Therefore, the nurse should administer 1 mL of digoxin (Lanoxin) to deliver a dose of 0.25 mg.

Correct Answer is B
Explanation
When discussing culturally competent care at a nursing staff inservice, the nurse should include information about the importance of focusing on clients’ cultures when providing care. Culture plays a significant role in determining when a client will seek medical care and how they will respond to treatment. Nonverbal communication is important in many cultures and can provide valuable information about a client’s needs and preferences. Nurses should strive to provide care that is respectful of and responsive to clients’ cultural beliefs and practices, rather than expecting clients to adapt to the care provided.
● “Culture plays no role in determining when a client will seek medical care.” This statement is incorrect because culture can play a significant role in determining when and how a client seeks medical care. Cultural beliefs and practices can influence a client’s understanding of health and illness, their attitudes towards healthcare providers, and their willingness to seek and adhere to treatment.
● “Nonverbal communication is important in few cultures.” This statement is incorrect because nonverbal communication is important in many cultures. Nonverbal cues such as body language, facial expressions, and gestures can convey important information about a client’s emotions, needs, and preferences. Understanding and responding to nonverbal communication can help nurses provide culturally competent care.
● “Nurses should expect clients to adapt to the care provided regardless of culture.” This statement is incorrect because it is not culturally competent to expect clients to adapt to the care provided without considering their cultural beliefs and practices. Nurses should strive to provide care that is respectful of and responsive to clients’ cultural beliefs and practices. This may involve adapting the care provided to meet the unique needs of each client.

Explanation
To determine the number of capsules the nurse will administer, we need to consider the dosage prescribed and the available strength of the capsules.
The prescription states: cephalexin (Keflex) 0.5 g p.o. qid (four times a day).
Given that the available strength of cephalexin capsules is 250 mg, we need to convert the prescribed dosage from grams (g) to milligrams (mg) to match the capsule strength.
1 g = 1000 mg
0.5 g = 0.5 * 1000 mg = 500 mg
Now we know that the prescribed dosage is 500 mg, and each capsule contains 250 mg.
To calculate the number of capsules needed, we divide the prescribed dosage by the strength of each capsule:
Number of capsules = Prescribed dosage / Capsule strength
Number of capsules = 500 mg / 250 mg
Number of capsules = 2
Therefore, the nurse will administer 2 capsules of cephalexin (Keflex) for each dose.
