A nurse is preparing to administer dextrose 5% in water (DW) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Do not use a trailing zero.)
The Correct Answer is ["8"]
To calculate the infusion rate for the IV solution, the nurse needs to use the formula:
Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
Plugging in the given values, we get:
Infusion rate (gtt/min) = 150 mL x 10 gtt/mL / 180 min
Simplifying, we get:
Infusion rate (gtt/min) = 8.33 gtt/min
Since the answer needs to be rounded to the nearest whole number, the final answer is:
Infusion rate (gtt/min) = 8 gtt/min

Explanation
Clindamycin is an antibiotic that can treat infections caused by staphylococci bacteria. It can be given by intermittent IV bolus, which means injecting the drug into a vein over a short period of time. To calculate the infusion rate for clindamycin, we need to use the formula:
Infusion rate (ml/hr) = Volume (ml) / Time (hr)
In this case, the volume is 50 ml and the time is 0.5 hr (30 min). Plugging these values into the formula, we get:
Infusion rate (ml/hr) = 50 ml / 0.5 hr
Infusion rate (ml/hr) = 100 ml/hr
Therefore, the nurse should set the IV pump to deliver 100 ml/hr of clindamycin.
Correct Answer is A
Explanation
A. Increased anteroposterior diameter of the chest
In emphysema, there is often hyperinflation of the lungs and destruction of the alveolar walls, leading to loss of lung elasticity. This results in increased air trapping and a characteristic "barrel chest" appearance, with an increased anteroposterior diameter.
B. Petechiae on chest:
Petechiae are small, red or purple spots caused by bleeding into the skin. They are not commonly associated with COPD and emphysema.
C. Oxygen saturation level 96%:
Oxygen saturation level of 96% is within the normal range. While oxygen saturation can be affected in COPD, the value provided is not indicative of severe hypoxemia.
D. Respiratory alkalosis:
Respiratory alkalosis is not typically associated with COPD and emphysema. In fact, respiratory acidosis is more commonly seen in these conditions due to impaired gas exchange and retention of carbon dioxide.
