A nurse is preparing to administer Ringer lactate 500 mL intravenous (IV) bolus to infuse over 3 hours. The drop factor of the manual IV tubing is 2 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["56"]

To calculate the infusion rate, we'll use the following formula:

Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min)) Drop factor (gtt/mL)

First, calculate the total time in minutes:

3 hours 60 minutes/hour = 180 minutes

Then, calculate the volume per minute:

500 mL / 180 minutes = 2.78 mL/min

Finally, multiply the volume per minute by the drop factor:

2.78 mL/min 20 gtt/mL = 55.6 gtt/min

Therefore, the nurse should set the manual IV infusion to deliver 56 gtt/min.

Correct Answer is B

Explanation

A. Urinary output: While important, urinary output is not the immediate priority over assessing vital signs and consciousness.
B. Blood pressure: This is the priority assessment post-operatively to monitor for signs of bleeding, shock, or other complications.
C. Pain level: Pain management is important but secondary to ensuring stable hemodynamics immediately post-surgery.
D. Level of consciousness: This is also crucial, but monitoring blood pressure is a more direct indicator of immediate postoperative stability and potential complications.

A. Pantoprazole B. Isosorbide mononitrate C. Acetylsalicylic acid D. Atorvastatin sodium

Correct Answer is B

Explanation

A. Pantoprazole: This medication is a proton pump inhibitor used to treat acid-related disorders and does not interact adversely with sildenafil.
B. Isosorbide mononitrate: This is correct. Isosorbide mononitrate is a nitrate used to treat angina. Combining it with sildenafil can lead to severe hypotension due to their additive vasodilatory effects.
C. Acetylsalicylic acid: This is incorrect. Acetylsalicylic acid (aspirin) is used for pain relief and cardiovascular protection and does not contraindicate sildenafil use.
D. Atorvastatin sodium: This is incorrect. Atorvastatin is a statin used to manage cholesterol levels and does not contraindicate sildenafil use.
