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. Brief Patient Health Questionnaire (Brief PHQ):
The Brief PHQ is a screening tool used to assess symptoms of depression. While it may be relevant to assess mood and emotional well-being, it is not specific to evaluating cognitive functioning or cognitive disorders.
B. Abnormal Involuntary Movements Scale (AIMS):
The AIMS is used to assess involuntary movements, particularly in individuals taking antipsychotic medications. It is not directly related to assessing cognitive disorders.
C,. Mental status examination (MSE)
Explanation:
When admitting an older adult client with a suspected cognitive disorder, including a mental status examination (MSE) as part of the assessment is crucial. The MSE is a structured assessment of a client's current cognitive functioning, emotional state, and thought processes. It helps to evaluate memory, attention, language, perception, orientation, mood, and other cognitive and emotional domains.
D. Scale for Assessment of Negative Symptoms (SANS):
The SANS is used to assess negative symptoms in individuals with schizophrenia. It focuses on features such as affective blunting, alogia, anhedonia, and other negative symptoms. While it may provide important information about a client's mental state, it is not primarily used to assess cognitive disorders.
Assessing cognitive function is a key component when evaluating older adult clients for cognitive disorders such as dementia or other cognitive impairments. The MSE provides valuable information to guide diagnosis and treatment planning for these conditions.
Correct Answer is ["0.5"]
Explanation
To calculate the amount of ziprasidone 10 mg IM from the available concentration of 20 mg/mL, you can use the formula:
Amount (mL) = Desired Dose (mg) / Concentration (mg/mL)
Amount (mL) = 10 mg / 20 mg/mL
Amount (Ml) = 0.5 mL
Therefore, the nurse should administer 0.5 mL of ziprasidone per dose.
