The healthcare provider prescribes 1 liter of lactate Ringer's to infuse in 8 hours. The IV administration set delivers 15 gtt/mL. How many mL/hour should the nurse program the infusion pump? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["125"]

Calculation:

Convert the total volume from liters (L) to milliliters (mL).

Total volume = 1 L × 1000 mL/L

= 1000 mL.

Infusion time = 8 hours.

Calculate the infusion rate in milliliters per hour (mL/hour).

Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hour)

= 1000 mL / 8 hours

= 125 mL/hour.

Answer: 125

Explanation

Rationale:

The second paddle should be placed on the left lateral chest, specifically:

Below the left nipple
At the mid-axillary line
Over the apex of the heart

For anterior-lateral defibrillator pad placement, the standard positions are: Right of the sternum, just below the clavicle as shown in the image and left side of the chest, at the mid-axillary line, roughly at the level of V6 in ECG placement.

A. Any antianxiety medications. B. Over-the-counter oral antipyretics. C. Nonsteroidal antiinflammatory drugs. D. Other beta-adrenergic blocker agents. E. Oral and subcutaneous anticoagulants.

Correct Answer is ["C","D"]

Explanation

Rationale:
A. Any antianxiety medications: Antianxiety medications are not contraindicated with ophthalmic timolol. Unless they directly impact heart rate or blood pressure significantly, they are generally safe to continue in clients with glaucoma using topical beta blockers.

B. Over-the-counter oral antipyretics: Oral antipyretics like acetaminophen are not known to interact adversely with timolol. These medications can be used safely unless otherwise contraindicated for specific patient conditions like liver disease.

C. Nonsteroidal antiinflammatory drugs: NSAIDs such as ibuprofen, when used long-term with beta blockers like timolol or carvedilol, may blunt the antihypertensive effect and increase renal risk, especially in clients on diuretics like spironolactone. This triple combination increases the chance of nephrotoxicity.

D. Other beta-adrenergic blocker agents: Using timolol with systemic beta blockers like carvedilol increases the risk of bradycardia, hypotension, and heart block. Though timolol is topical, systemic absorption can still occur, requiring caution when combining with other beta-blockers.

E. Oral and subcutaneous anticoagulants: There is no direct contraindication between timolol and anticoagulants. Unless the client has bleeding risks associated with other therapies or conditions, concurrent use is generally acceptable.
