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

Correct Answer is D
Explanation
A. Metabolic alkalosis with full compensation:
This is not the correct interpretation. Metabolic alkalosis is characterized by an elevated pH and elevated bicarbonate (HCO3-) levels. In this case, the pH is low (acidosis), and the bicarbonate level is within the normal range, suggesting a respiratory issue rather than a metabolic one.
B. Respiratory alkalosis with partial compensation:
This is not the correct interpretation. Respiratory alkalosis is characterized by an elevated pH and decreased PaCO2. In this case, the pH is low (acidosis), and the PaCO2 is elevated, indicating respiratory acidosis rather than alkalosis.
C. Metabolic acidosis with partial compensation:
This is not the correct interpretation. Metabolic acidosis is characterized by a low pH and decreased bicarbonate (HCO3-) levels. In this case, the bicarbonate level is within the normal range, and the elevated PaCO2 suggests a respiratory issue, not metabolic acidosis.
D. Respiratory acidosis with no compensation:
This is the correct interpretation. Respiratory acidosis is characterized by a low pH and an elevated PaCO2. The normal bicarbonate level indicates that compensatory mechanisms (such as the kidneys increasing bicarbonate reabsorption) have not fully corrected the pH imbalance, leading to respiratory acidosis with no compensation.
Correct Answer is ["2 "]
Explanation
To calculate the number of tablets that the nurse should administer with each dose, the nurse needs to use the formula:
D/H x Q = X
where D is the desired dose, H is the dose on hand, Q is the quantity of the drug, and X is the amount to give.
In this case, D is 250 mg, H is 125 mg, Q is 1 tablet, and X is unknown. Plugging these values into the formula, we get:
250/125 x 1 = X
Simplifying, we get:
2 = X
Therefore, the nurse should administer 2 tablets with each dose of amoxicillin.
