A nurse is preparing to administer haloperidol 0.5 mg by mouth to an older adult client. The amount available is haloperidol oral concentrate 2 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.25"]
To calculate the amount of haloperidol oral concentrate the nurse should administer, we can use the following equation:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 0.5 mg and the concentration of the haloperidol oral concentrate is 2 mg/mL.
Volume (mL) = 0.5 mg / 2 mg/mL
Volume (mL) = 0.25 mL

Correct Answer is B
Explanation
By using short, simple sentences, the nurse can effectively communicate with the client who is exhibiting signs of agitation and anxiety. This communication style can help reduce stress and confusion for the client and promote understanding.
Asking the client if they would like to watch television: While providing options for activities can be beneficial, it is important to address the client's current state of agitation and anxiety before suggesting any specific activities.
Allowing the client to have 1 hour of time alone in their room: While some clients may prefer solitude, in this case, the client's pacing and hand-wringing indicate signs of distress and may require therapeutic interventions rather than isolation.
Moving the client to a table where other clients are playing cards: This option may not address the client's current state of anxiety and pacing. Placing the client in a social setting with other clients might increase their distress and agitation.
Correct Answer is B
Explanation
Explanation
B.Hypertension
Tranylcypromine is a monoamine oxidase inhibitor (MAOI) used to treat depression. One of the potential adverse effects of MAOIs is hypertensive crisis, which can be triggered by the consumption of foods high in tyramine. Tyramine-rich foods, such as aged cheeses, cured meats, certain wines, and fermented products, can cause the release of norepinephrine, leading to a sudden increase in blood pressure.
Monitoring the client for hypertension is crucial because a hypertensive crisis can be life-threatening. Signs and symptoms of hypertensive crisis may include severe headache, chest pain, palpitations, blurred vision, anxiety, and shortness of breath. If these symptoms occur, immediate medical intervention is required.
The other options are not specifically associated with the adverse effects of tranylcypromine:
Hyperglycemia in (option A) is not typically associated with tranylcypromine. However, it is important to monitor blood glucose levels in clients with pre-existing diabetes, as tranylcypromine can affect blood sugar control.
Hematuria (blood in the urine) in (option C) is not a common adverse effect of tranylcypromine.
Tinnitus (ringing in the ears) in (option D) is not a commonly reported adverse effect of tranylcypromine.
