A nurse is caring for a client who is prescribed tetracycline 2 grams daily PO in four divided doses every 6 hr. Available is tetracycline 250 mg capsules. How many capsules 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 ["2"]
To calculate the number of capsules that the nurse should administer per dose, the nurse should first divide the total daily dose of tetracycline by the number of doses per day. This gives the dose per administration:
2 grams / 4 doses = 0.5 grams per dose
Next, the nurse should convert the dose from grams to milligrams, since the available capsules are in milligrams. There are 1000 milligrams in one gram, so the nurse should multiply the dose by 1000:
0.5 grams x 1000 mg/g = 500 mg per dose
Finally, the nurse should divide the dose in milligrams by the strength of each capsule, which is 250 mg. This gives the number of capsules that the nurse should administer per dose:
500 mg / 250 mg/capsule = 2 capsules per dose
Therefore, the nurse should administer 2 capsules of tetracycline every 6 hours to the client.

Correct Answer is ["2"]
Explanation
The nurse is preparing to administer benztropine 2 mg IM every 12 hours. The concentration of the available benztropine is 1 mg/mL.
To calculate the volume (mL) of the medication needed for the prescribed dose, you can use the formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Plugging in the values:
Volume (mL) = 2 mg / 1 mg/mL = 2 mL
So, the nurse should administer 2 mL of benztropine 1 mg/mL for each dose. Since we're looking for a whole number, we round to the nearest whole number, which is 2 mL.
Correct Answer is A
Explanation
A. "Tell me what is concerning you."
This response is the most therapeutic option. It invites the spouse to share their concerns and feelings, showing empathy and active listening. It opens the door for effective communication and understanding the spouse's perspective.
B. "Your husband is making really good progress."
While this response provides information about the husband's progress, it doesn't directly address the spouse's concerns or feelings. The spouse's emotional state needs to be acknowledged and explored before discussing the husband's progress.
C. "Did your husband say something to upset you?"
This response makes an assumption that the husband said something to upset the spouse. It might come across as accusatory or dismissive of the spouse's feelings. It's important to give the spouse the opportunity to express their emotions in their own words.
D. "Crying helps us let things out and we feel better."
This response offers a general statement about crying, but it doesn't directly address the spouse's concerns or invite further conversation. While it's true that crying can be cathartic, the focus here should be on understanding the spouse's specific worries.
