A nurse caring for a cut is who has a deep vein thrombosis and is prescribed heparin by continuous infusion at 1,200 U/hr. Ava A 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 number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["24"]

To calculate the mL/hr for the heparin infusion, you can use the formula:

mL/hr = (Total units required per hour) / (Units/mL in the solution)

Given:

Total units required per hour = 1,200 U/hr

Units/mL in the solution = 25,000 U / 500 mL = 50 U/mL

Plugging in the values:

mL/hr = (1,200 U/hr) / (50 U/mL)

mL/hr = 24 mL/hr (rounded to the nearest tenth)

Therefore, the nurse should set the IV pump to deliver 24 mL/hr for the heparin infusion.

Correct Answer is A

Explanation

A.Lithium is excreted through the kidneys, and dehydration and sodium depletion increase the risk of lithium toxicity. A client who runs 4 miles outdoors every afternoon is at risk of excessive sweating and fluid loss, which can lead to dehydration and sodium depletion. This reduces lithium excretion, leading to toxic levels in the blood.

B. Anormal sodium intake helps maintain lithium balance. A low sodium intake increases lithium retention, but 2-3 grams/day is within the normal recommended range.

C. Adequate hydration helps prevent lithium toxicity. Clients on lithium should drink 2–3 liters of fluid daily to promote kidney function and lithium excretion.
D. Tyramine-rich foods (e.g., aged cheese, cured meats) are a concern for clients on monoamine oxidase inhibitors (MAOIs), not lithium. Tyramine does not affect lithium levels.

A. “I need to make sure that the potential victim is warned." B. "I need to keep the information confidential due to the client's right to privacy." C. “I can only discuss the client's threats with a court order." D. "I should verbally report this information to the psychiatrist."

Correct Answer is A

Explanation

A. "I need to make sure that the potential victim is warned."

Explanation: Correct Answer. When a client threatens to harm a specific individual, it's important to take steps to ensure the safety of both the client and the potential victim. Warning the potential victim or taking appropriate measures to protect them is an important action to take.

B. "I need to keep the information confidential due to the client's right to privacy."

Explanation: While respecting a client's right to privacy is important, when there's a threat of harm to an individual, it becomes a matter of safety that takes precedence over confidentiality.

C. "I can only discuss the client's threats with a court order."

Explanation: This statement is incorrect. When there's a credible threat to harm an individual, waiting for a court order is not an appropriate or timely response. Immediate actions should be taken to ensure safety.

D. "I should verbally report this information to the psychiatrist."

Explanation: While involving the psychiatrist is important for the client's overall care, it's essential to take more immediate steps to ensure the safety of the potential victim, such as notifying the appropriate authorities or taking appropriate precautions.
