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
Deep-vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, usually in the legs. Bed rest is often recommended for clients with DVT to reduce the risk of the clot dislodging and causing a pulmonary embolism. By minimizing movement and keeping the leg elevated, the nurse can help prevent further complications.
The other options listed are incorrect:
- Massage the affected extremity every 4 hours: Massaging the affected extremity can dislodge the clot, increasing the risk of a pulmonary embolism. It is contraindicated and should not be performed in clients with DVT.
- Apply an ice pack to the affected extremity for 20 minutes every 2 hours: While applying cold compresses or ice packs may be useful in some situations to reduce swelling or pain, it is not recommended for clients with DVT. Heat application or cold application should be avoided because they can promote blood circulation and potentially dislodge the clot.
- Administer aspirin for pain: Aspirin is not typically used for pain management in DVT. Anticoagulant therapy is the primary treatment for DVT, and specific anticoagulant medications are prescribed to prevent further clot formation and reduce the risk of complications.
Correct Answer is B
Explanation
Hypertensive crisis is a severe increase in blood pressure that can lead to organ damage or other complications. Prompt assessment and intervention are necessary to prevent further escalation of blood pressure and potential complications.
While all the clients mentioned require attention, the client with elevated blood pressure and a headache poses a higher immediate risk. The nurse should assess the client's blood pressure, evaluate for signs of target organ damage, and initiate appropriate interventions, which may include administering antihypertensive medications as prescribed and monitoring closely for any changes in the client's condition.
The client who is postoperative and reports intermittent nausea can be assessed and managed after addressing the client with the elevated blood pressure and headache.
The client scheduled for surgery in 2 hours can be addressed according to the scheduled timeline.
