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 A
Explanation
A. Weight gain and dry mouth: Weight gain and dry mouth are common adverse effects of lithium at therapeutic levels. They are not immediately dangerous but can affect compliance with the medication regimen.
B. Oliguria (reduced urine output) and muscle weakness are more concerning symptoms. They can indicate potential toxicity, especially oliguria, which suggests possible renal impairment, a serious concern with lithium therapy.
C. Hallucinations and blurred vision are more severe and typically associated with lithium toxicity rather than therapeutic levels. They indicate a need for immediate medical attention.
D. Coarse hand tremors and confusion: Coarse hand tremors and confusion are signs of lithium toxicity. At therapeutic levels, fine hand tremors can occur, but coarse tremors and confusion suggest higher serum levels.These symptoms are associated with toxicity and require urgent medical evaluation.
Correct Answer is C
Explanation
A. “Decreased startle response to loud noises.”: Individuals with PTSD often have an exaggerated startle response to loud noises or unexpected stimuli. This heightened startle response is a common symptom of hyperarousal associated with PTSD. Therefore, a decreased startle response would be unexpected in this context.
B. “Reports uninterrupted sleep of 10 to 12 hr each night.”: Sleep disturbances are common among individuals with PTSD. Symptoms can include difficulty falling asleep, staying asleep, or experiencing nightmares related to the traumatic event. Therefore, reports of uninterrupted sleep for 10 to 12 hours each night would be unexpected in someone with PTSD.
C. “Reluctance to discuss the event that precipitated the distress.”: Avoidance of trauma-related thoughts, feelings, or reminders is a hallmark symptom of PTSD. Individuals with PTSD often avoid discussing or thinking about the traumatic event to cope with distressing memories or emotions. Therefore, reluctance to discuss the precipitating event is a common manifestation of PTSD.
D. “Reports feelings of acute distress that began 2 weeks ago.”: PTSD symptoms typically develop shortly after experiencing a traumatic event, but the diagnosis of PTSD requires that symptoms persist for at least one month. Acute distress that began two weeks ago may indicate an acute stress reaction rather than PTSD. PTSD involves persistent symptoms beyond the acute phase of the trauma.
