A nurse is preparing to administer 1,000 mL of lactated Ringer's IV over 6 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 ["28"]
To calculate the IV infusion rate in drops per minute (gtt/min), you can use the following formula:
IV infusion rate (gtt/min) =(Total volume (mL)×Drop factor (gtt/mL)) / Total time (min)
Given:
Total volume = 1000 mL
Drop factor = 10 gtt/mL
Total time = 6 hours = 6 hours × 60 minutes/hour = 360 minutes
Substitute the given values into the formula:
IV infusion rate (gtt/min) = (1000mL×10gtt/mL)/360 min
IV infusion rate (gtt/min) = 10,000/360
IV infusion rate (gtt/min)≈27.78gtt/min
Rounding to the nearest whole number, the IV infusion rate is approximately 28 gtt/min

Correct Answer is B
Explanation
A) Chronic diarrhea:
Overuse of laxatives is more likely to lead to chronic constipation rather than chronic diarrhea. Laxatives are typically used to treat constipation by promoting bowel movements, but overuse can disrupt normal bowel function and result in long-term constipation.
B) Chronic constipation.
Overuse of laxatives can lead to dependence on laxatives for bowel movements and can cause the smooth muscle in the colon to become less responsive to normal stimuli, resulting in decreased muscle tone. This can eventually lead to chronic constipation, where the colon becomes less effective at moving stool through the digestive tract, resulting in infrequent or difficult bowel movements.
C) Frequent vomiting:
Overuse of laxatives does not typically lead to frequent vomiting. Vomiting is more commonly associated with conditions affecting the upper gastrointestinal tract, such as gastroenteritis, gastritis, or other gastrointestinal disorders.
D) Chronic nausea:
Overuse of laxatives may cause gastrointestinal discomfort or upset stomach, but it is not typically associated with chronic nausea. Chronic nausea may be caused by various factors such as gastrointestinal disorders, medications, or other underlying medical conditions unrelated to laxative use.
Correct Answer is ["B","C","D","E"]
Explanation
A. Wheezing: Wheezing is not a typical symptom of allergic rhinitis. It is more commonly associated with asthma or other lower respiratory conditions.
B. Sneezing: Sneezing is a common symptom of allergic rhinitis. It is often triggered by exposure to allergens such as pollen, dust mites, or pet dander.
C. Watery eyes: Watery eyes, also known as allergic conjunctivitis, frequently accompany allergic rhinitis. This symptom occurs due to inflammation of the conjunctiva in response to allergen exposure.
D. Nasal congestion: Nasal congestion, or a stuffy nose, is a hallmark symptom of allergic rhinitis. It occurs as a result of inflammation and swelling of the nasal mucosa in response to allergens.
E. Urticaria: Urticaria, commonly referred to as hives, may occur in some individuals with allergic rhinitis. However, it is more commonly associated with other types of allergic reactions, such as food allergies or drug allergies.
