A nurse is preparing to administer dextrose 5% in water 350 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 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.)
The Correct Answer is ["19"]
Drip rate (gtt/min) = (Volume to be infused in mL × Drop factor) ÷ Time of infusion in minutes
Given:
Volume to be infused = 350 mL Drop factor = 10 gtt/mL
Time of infusion = 3 hours = 180 minutes
Plugging these values into the formula:
Drip rate = (350 mL × 10 gtt/mL) ÷ 180 min Drip rate ≈ (3500 gtt) ÷ 180 min
Drip rate ≈ 19.4 gtt/min
Rounding to the nearest whole number, the drip rate is approximately 19 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver 19 gtt/min.

Correct Answer is B
Explanation
A. Insomnia: Pioglitazone is not typically associated with insomnia as an adverse effect.
Insomnia is more commonly associated with stimulant medications or certain medical conditions.
B. Fluid retention: Pioglitazone, a thiazolidinedione, can cause fluid retention as an adverse effect. This can lead to peripheral edema and exacerbation of heart failure, particularly in
susceptible individuals. Monitoring for signs and symptoms of fluid retention, such as peripheral edema and weight gain, is essential.
C. Tinnitus: Tinnitus is not a commonly reported adverse effect of pioglitazone. Tinnitus is more commonly associated with medications such as certain antibiotics, NSAIDs, and ototoxic drugs.
D. Orthostatic hypotension: Orthostatic hypotension is not typically associated with pioglitazone.
It is more commonly associated with medications that affect blood pressure regulation, such as antihypertensives and alpha-blockers.
Correct Answer is D
Explanation
A. Taking theophylline with coffee may increase its absorption and risk of adverse effects due to caffeine's effects on metabolism, so this statement is not appropriate.
B. Theophylline is a bronchodilator that may cause dehydration as a side effect, so limiting fluid intake is not recommended.
C. Theophylline sustained-release capsules should not be opened, crushed, or chewed, as it can alter the drug's release characteristics and increase the risk of adverse effects.
D. Monitoring blood levels of theophylline is essential to ensure therapeutic effectiveness and avoid toxicity, so the client's understanding of the need for blood level monitoring indicates comprehension of the teaching.
