A nurse is caring for a client who is receiving haloperidol 2 mg IM every 6 hr. Available is haloperidol 5 mg/mL. How many mu should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
To find out how many milliliters (mL) the nurse should administer, we first need to determine the total dose required per administration. The client is receiving haloperidol 2 mg IM every 6 hours.
First, let's calculate the total dose required per administration:
2 mg (total dose) / 1 dose = 2 mg
Next, we need to determine how many milliliters (mL) of the medication solution contain this dose. The concentration of the haloperidol solution is 5 mg/mL.
We can set up a proportion to find the volume of the solution:
2 mg (dose required) / x mL (volume to administer) = 5 mg/mL (concentration)
Cross-multiplying:
2 mg * 1 mL = 5 mg * x mL
2 mL = 5x
To isolate x (the volume to administer), we divide both sides by 5:
x = 2 mL / 5
x = 0.4 mL
So, the nurse should administer 0.4 mL of haloperidol

Correct Answer is D
Explanation
A. A client who has new-onset delirium: Delirium is characterized by acute confusion and changes in cognition, often due to underlying medical conditions. Assertiveness training may not be appropriate for someone experiencing delirium, as their cognitive impairment may interfere with their ability to participate effectively in the therapy session.
B. A client who is experiencing auditory hallucinations: Auditory hallucinations involve perceiving sounds or voices that are not actually present. Assertiveness training may not directly address the underlying cause of auditory hallucinations, which typically require other therapeutic approaches such as medication management and cognitive-behavioral therapy.
C. A client who is experiencing mania: Mania is a state of elevated mood, increased energy, and often impulsivity. While assertiveness training could potentially be beneficial for individuals with bipolar disorder during periods of stability, it may not be appropriate during acute manic episodes when the client's judgment and insight may be impaired.
D. A client who has somatic symptom disorder: Somatic symptom disorder involves experiencing distressing physical symptoms that are disproportionate to any identified medical condition. Assertiveness training could be helpful for individuals with somatic symptom disorder to effectively communicate their concerns with healthcare providers and advocate for appropriate care.
Correct Answer is B
Explanation
A. Polyphagia: Polyphagia refers to excessive hunger or increased appetite. Cocaine use is not typically associated with increased appetite; in fact, it often suppresses appetite. Therefore, polyphagia is not an expected finding.
B. Fever: Cocaine use can lead to an increase in body temperature due to its stimulant effects on the central nervous system. Therefore, fever is a possible finding associated with cocaine use.
C. Bradycardia: Cocaine use is more commonly associated with tachycardia, an elevated heart rate, rather than bradycardia. Stimulants like cocaine typically increase heart rate and can cause palpitations and arrhythmias.
D. Oliguria: Oliguria refers to decreased urine output. While cocaine use can have various effects on the body, it is not typically associated with oliguria. Instead, it can lead to increased urinary frequency due to its stimulant effects.
