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 C
Explanation
A. Explain to the client that the behavior was unacceptable: While addressing the behavior is important, it is more effective to first establish clear limits and boundaries to prevent further incidents.
B. Explore the truth of the client’s statements: This step involves assessing the client's statements and understanding their perspective, which is important but can be done after setting behavioral limits.
C. Set behavioral limits for the client: Establishing clear behavioral limits is crucial for maintaining safety and order in the psychiatric unit. It helps ensure that the client understands what is expected of them and the consequences of unacceptable behavior. This is particularly important if the client has exhibited aggressive behavior, as it helps prevent further incidents and maintains a safe environment for everyone.
D. Establish a client relationship: Building a therapeutic relationship is essential for effective treatment, but it should be done in the context of a safe environment where clear behavioral expectations have already been established.
Correct Answer is C
Explanation
A. A pretreatment electroencephalogram (EEG) will be done.
An EEG is not typically necessary when starting valproate for bipolar disorder. EEGs are more commonly used to assess brain activity in the context of epilepsy.
B. High serum sodium levels can cause toxic levels of valproate.
Sodium levels are not directly related to the toxic levels of valproate. The primary concern with valproate is its impact on liver function and potential for hepatotoxicity.
C. Liver function tests must be monitored.
Explanation: Valproate is an antiepileptic and mood-stabilizing medication commonly used to treat bipolar disorder. One of the potential side effects of valproate is hepatotoxicity (liver damage). Therefore, monitoring liver function tests (such as serum transaminases) is important to assess the medication's impact on the liver and to ensure the client's safety.
D. Thyroid function tests should be performed every 6 months.
While thyroid function tests might be important for some medications, monitoring thyroid function is not a primary consideration when using valproate. The main focus with valproate is on liver function monitoring.
