A client is to receive one liter of normal saline intravenously over six hours. The tubing delivers 15 drops per milliliter.
How many drops per minute should a nurse regulate the infusion to deliver?
42.
84.
100.
166.
The Correct Answer is A
Step 1 is: Convert 1 liter to milliliters 1 L = 1000 mL
Step 2 is: Convert 6 hours to minutes 6 × 60 = 360 min
Step 3 is: Calculate drops per minute using tubing drop factor (1000 mL ÷ 360 min) × 15 gtt/mL = (2.77 mL/min) × 15 = 41.66 drops/min
Step 4 is: Round to the nearest whole number Final answer: 42 drops per minute

Correct Answer is D
Explanation
This question evaluates the client’s understanding of the most important infection control measure for hepatitis A, which is hand hygiene. Hepatitis A is transmitted through ingestion of contaminated food and water or through direct contact with an infectious person’s feces.
Washing hands after using the toilet can prevent the spread of the virus to others and to oneself.
Choice A is wrong because eating raw shellfish is not a risk factor for hepatitis A unless the shellfish is contaminated with the virus from polluted water.
Choice B is wrong because cooking pork products does not affect hepatitis A transmission, as the virus is not found in pork or other meats.
Choice C is wrong because traveling out of the country is not a risk factor for hepatitis A unless the destination has poor sanitation and hygiene conditions.
Correct Answer is A
Explanation
Formed stool two times per day, every day, for one week. This indicates that bowel training is attaining the desired outcome because it shows regularity and consistency of bowel movements without the use of laxatives or enemas.
Choice B is wrong because soap sud enemas are not recommended for bowel training as they can irritate the bowel and cause fluid and electrolyte imbalance.
Choice C is wrong because continued use of laxatives can inhibit the natural defecation reflexes and cause dependency.
Choice D is wrong because a formed, soft stool at regular intervals without the use of a laxative is a normal defecation pattern, not an indication of fecal incontinence.
