A nurse is preparing to administer heparin at 1,000 units/hr via continuous IV infusion to a client who had a coronary artery bypass graft. Available is heparin 25,000 units in dextrose 5% in water in 250 mL. The nurse should set the IV pump to deliver how many mL/hr? (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 ["10"]

The formula to calculate the IV flow rate is:

mL/hr =

(Desired dose (units/hr)×Total volume (mL))/ Available dose

Substituting the given values:

(1,000×250)/25000

= 250,000/25,000

= 10ml/hr

Correct Answer is D

Explanation

A. "You can take this medication with milk." This is incorrect because dairy products interfere with the absorption of tetracycline and should be avoided when taking the medication.
B. "You should take this medication at bedtime." This is incorrect because taking tetracycline at bedtime increases the risk of esophageal irritation. It should be taken with a full glass of water while sitting or standing upright.
C. "Constipation is an adverse effect of this medication." This is incorrect because tetracycline is more commonly associated with diarrhea rather than constipation.
D. "Light sensitivity is an adverse effect of this medication." This is correct because tetracycline can cause photosensitivity, making the skin more susceptible to sunburn. Clients should be advised to use sunscreen and wear protective clothing when exposed to sunlight.

A. Constipation B. Visual disturbances C. Dry mouth D. Irregular pulse

Correct Answer is D

Explanation

A. Constipation is a common side effect of risperidone due to its anticholinergic effects. However, it is not the priority because it is not immediately life-threatening.
B. Visual disturbances can occur with risperidone, but they are not as urgent as cardiovascular abnormalities.
C. Dry mouth is another anticholinergic side effect, but it is not a priority concern compared to an irregular pulse.
D. Irregular pulse is the priority finding because risperidone can prolong the QT interval, increasing the risk of serious cardiac arrhythmias, including torsades de pointes, which can be life-threatening. Therefore, this finding should be reported to the provider immediately.
