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 A
Explanation
A. "Are you thinking of harming yourself?": Correct
This is the priority response because it directly addresses the client's statement about being better off gone, which raises concerns about potential suicidal thoughts. Asking this question allows the nurse to assess the client's risk of self-harm or suicide and take appropriate actions to ensure their safety.
B. "Do you really think your family would be better off without you?": Incorrect
While this response attempts to engage the client in a conversation, it doesn't directly address the immediate concern of suicidal thoughts. It's important to prioritize assessing the client's safety before exploring their feelings about their family's perspective.
C. "When did you first start feeling this way?": Incorrect
While understanding the client's history and the onset of their feelings is important, it's not the priority response in this situation. Assessing the client's risk of harm takes precedence over gathering historical information.
D. "Tell me what is happening right now.": Incorrect
This response doesn't directly address the client's statement about being better off gone and doesn't assess the immediate risk of self-harm or suicide. While understanding the client's current situation is valuable, safety concerns should be addressed first.
Correct Answer is ["0.75"]
Explanation
To calculate the volume (ml) of haloperidol decanoate needed for a dose of 75 mg, you can use the following formula:
Volume (ml) = Dose (mg) / Concentration (mg/ml)
Given:
Dose = 75 mg
Concentration = 100 mg/ml
Plugging in the values:
Volume (ml) = 75 mg / 100 mg/ml
Volume (ml) = 0.75 ml
Rounding to the nearest hundredth:
Volume (ml) = 0.75 ml
So, the nurse should administer 0.75 ml of haloperidol decanoate for the dose of 75 mg.
