A nurse is caring for a client who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Available is heparin 25,000 units in 500 mL DSW. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["24"]
To calculate the infusion rate, use the formula:
(rate in mL/hr) = (desired dose in units/hr) / (available dose in units/mL)
In this case, the desired dose is 1,200 units/hr and the available dose is 25,000 units / 500 mL = 50 units/mL. Therefore,
(rate in mL/hr) = (1,200 units/hr) / (50 units/mL) = 24 mL/hr
Round the answer to the nearest tenth/whole number and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 24 mL/hr.

Correct Answer is A
Explanation
Planning to lower saturated fats to 10 percent of the daily calorie intake is a good dietary recommendation for a client who has hypertension, as it can help lower cholesterol, prevent atherosclerosis, and reduce the risk of cardiovascular complications.
a. "Limit your alcohol consumption to three drinks a day." is not correct, as it is too high for a client who has hypertension. The client should limit alcohol consumption to no more than one drink a day for women and two drinks a day for men, as alcohol can increase blood pressure and interfere with medication effectiveness.
c. "Diuretics are the first type of medication to control hypertension." is not accurate, as diuretics are not always the first choice of medication for hypertension. The choice of medication depends on the client's individual factors, such as age, race, comorbidities, and contraindications. Diuretics are one of the classes of antihypertensive drugs that can be used alone or in combination with other drugs.
d. "Reaching your goal blood pressure will occur within 2 months." is not realistic, as reaching the goal blood pressure may take longer than 2 months, depending on the client's baseline blood pressure, response to treatment, adherence to lifestyle modifications, and presence of other conditions. The client should monitor his blood pressure regularly and follow up with the provider as needed.
Correct Answer is D
Explanation
Hemorrhagic stroke is a type of stroke that occurs when a blood vessel ruptures in the brain, causing bleeding and increased intracranial pressure. The client's symptoms of sudden, severe headache, vomiting, seizure, and
unresponsiveness are consistent with hemorrhagic stroke. The client's elevated blood pressure and temperature are also risk factors for hemorrhagic stroke.
Thrombotic stroke is a type of stroke that occurs when a blood clot forms in an artery that supplies blood to the brain, causing ischemia and tissue damage. The client's symptoms are not typical of thrombotic stroke, which usually has a gradual onset and affects one side of the body.
Transient ischemic atack (TIA) is a temporary interruption of blood flow to the brain, causing neurologic deficits that resolve within 24 hours. The client's symptoms are not indicative of TIA, which does not cause loss of consciousness or permanent brain damage.
Embolic stroke is a type of stroke that occurs when a blood clot or other debris travels from another part of the body to the brain, causing occlusion and ischemia. The client's symptoms are not characteristic of embolic stroke, which usually has a sudden onset and affects one side of the body.
