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
Remaining with the client provides support and ensures their safety. The client's behavior indicates distress, and having a nurse nearby can help the client feel more comfortable and secure.
B. Give the client a PRN sleeping medication:
Explanation: Administering a sleeping medication should not be the first response, especially if the client is agitated. It's important to address the underlying cause of the agitation and consider other interventions before resorting to medication.
C. Encourage the client to go back to bed:
Explanation: Encouraging the client to go back to bed might not be effective if they are experiencing significant distress or anxiety. It's better to address their emotional state first before suggesting any changes in activity.
D. Explore alternatives to pacing the floor with the client:
Explanation: This is a reasonable course of action. Exploring alternatives to the client's current behavior can help address their distress and find ways to manage their emotions more effectively.
Correct Answer is D
Explanation
A. "Tell me who you think doesn't care about you."
Explanation: This response might come across as confrontational or defensive, which could discourage the client from opening up further. It's important to offer support and understanding rather than putting the client on the spot.
B. "Of course people care. Your family comes to visit every day."
Explanation: While it's true that the client's family visits, depression often distorts perception and emotions. Telling the client that people care might not be fully effective in addressing their feelings of worthlessness.
C. "Why do you feel that way?"
Explanation: This response opens the door for the client to express their emotions and thoughts. It encourages further conversation and helps the nurse understand the underlying causes of the client's feelings.
D. "I care about you, and I am concerned that you feel so sad."
Explanation: Correct Answer. This response shows empathy and genuine concern for the client's well-being. It acknowledges the client's emotions, offers support, and validates their feelings.
