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.)

Answer and Explanation

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 C

Explanation

A. The client is unwilling to accept that treatment is needed.

This alone may not be sufficient to keep the client under a 72-hour hold. While a person's refusal to accept treatment may indicate a need for care, it might not meet the criteria for involuntary commitment unless there is an immediate danger to the individual or others.

B. The client states that she does not like the neighbor.

Disliking a neighbor is not typically a sufficient reason to place someone under a 72-hour psychiatric hold. The criteria for involuntary commitment usually revolve around a person's potential to harm themselves or others due to their mental state.

C. The client is a danger to herself or others.

Explanation:

In many jurisdictions, a 72-hour psychiatric hold, also known as an involuntary psychiatric hold or emergency detention, allows mental health professionals to detain a person who is considered a danger to themselves or others due to their mental condition. This is done to ensure the safety of the individual and those around them. The hold provides a brief period during which a psychiatric assessment can be conducted to determine the appropriate course of action for the person's mental health treatment.

D. The client states that she plans to move out of the state immediately.

While this statement might raise concerns about the client's stability, it generally would not meet the criteria for a 72-hour hold unless there is clear evidence that the client's immediate move would pose a risk to their own safety or the safety of others. The hold is more focused on imminent danger rather than potential future actions.

A. He will monitor your lithium levels closely while you are taking this medication." B. This medication is addictive, so you will need to discontinue it in six months." C. "Weight gain should be reported to your provider as an indication of lithium toxicity." D. "Your provider may prescribe a diuretic if you have trouble urinating while taking lithium."

Correct Answer is A

Explanation

Lithium is a commonly used medication for treating bipolar disorder, and therapeutic drug monitoring is crucial to ensure its effectiveness and prevent potential toxicity. Monitoring the client's lithium levels in the blood is important because lithium has a narrow therapeutic range, meaning that levels that are too low might not provide the desired therapeutic effect, while levels that are too high can lead to toxicity.

B) "This medication is addictive, so you will need to discontinue it in six months."

Lithium is not considered addictive. It's important to provide accurate information about the nature of the medication to avoid unnecessary concerns.

C) "Weight gain should be reported to your provider as an indication of lithium toxicity."

While weight gain can be a side effect of some medications, it's not a specific indicator of lithium toxicity. Lithium toxicity is characterized by a range of symptoms including tremors, confusion, nausea, vomiting, and excessive thirst, among others.

D) "Your provider may prescribe a diuretic if you have trouble urinating while taking lithium."

Diuretics are generally not recommended with lithium because they can increase the risk of lithium toxicity. Lithium can affect kidney function, and using diuretics may exacerbate this effect. The client should be advised not to use diuretics without consulting their healthcare provider.
