. A nurse is preparing to administer 0.9% sodium chloride 1 L IV to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/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 ["31"]

Desired volume: 1 L = 1,000 mL

Infusion time: 8 hours = 480 minutes

Drop factor: 15 gtts/mL

Formula: (Volume (mL) ÷ Time (min)) × Drop factor (gtts/mL)

= (1000 ÷ 480) × 15

= 31.25

Rounded to the nearest whole number: 31 gtt/min

Correct Answer is D

Explanation

A. Headache: Headaches are not a common adverse effect of atenolol, a beta-blocker, though they can occur in some individuals. They are more frequently associated with other medications.

B. Cough: A persistent cough is usually associated with ACE inhibitors, not beta-blockers like atenolol.

C. Elevated Blood Pressure: Atenolol is an antihypertensive medication. Its purpose is to lower blood pressure, so elevated blood pressure would indicate therapy failure, not an adverse effect.

D. Bradycardia: Atenolol, a beta-blocker, slows down the heart rate and can lead to bradycardia (a heart rate that is too slow), which is a common adverse effect to monitor for.

A. Crackles B. Productive cough C. Hepatomegaly D. Dizziness

Correct Answer is C

Explanation

A. Crackles: Crackles in the lungs are a sign of left-sided heart failure, as fluid backs up into the pulmonary system.

B. Productive cough: A productive cough is also more commonly associated with left-sided heart failure, as it can result from fluid accumulation in the lungs.

C. Hepatomegaly: Hepatomegaly is a sign of right-sided heart failure, as blood backs up into the systemic circulation, leading to congestion in the liver.

D. Dizziness: Dizziness may occur in left-sided heart failure due to decreased cardiac output, but it is not a typical finding in right-sided heart failure.
