A nurse is preparing to infuse 1,000 ml of a total parenteral nutrition solution IV over 24 hr.
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.)
The Correct Answer is ["42"]
Volume to infuse= 1000ml Duration= 24 hrs
Rate= volume/duration
=1000/24
= 41.67ml/hr
Rounded off to the nearest whole number = 42ml/hr

B. Eating bananas can be beneficial because they are rich in potassium, which can help replace electrolytes lost during diarrhea.
C. Drinking hot tea, especially caffeinated varieties, can act as a diuretic and may worsen dehydration.
D. Carbonated beverages can contribute to gas and bloating, which may worsen discomfort in someone experiencing diarrhea.
Correct Answer is A
Explanation
A. Vitamin C deficiency, also known as scurvy, can lead to impaired collagen synthesis, which is essential for maintaining the integrity of connective tissues, including the skin. Without an adequate supply of vitamin C, the skin becomes fragile and prone to breakdown, leading to the development of ulcers and wounds.
B. Hypertension is not directly associated with vitamin C deficiency. However, vitamin C deficiency may indirectly contribute to hypertension due to its role in maintaining blood vessel health and endothelial function.
C. Tachycardia is not directly associated with vitamin C deficiency. However, severe vitamin C deficiency (scurvy) can lead to fatigue and weakness, which may result in an increased heart rate as the body tries to compensate for reduced oxygen delivery to tissues.
D. Kidney stones are not typically associated with vitamin C deficiency. However, excessive intake of vitamin C supplements may increase the risk of kidney stone formation in susceptible individuals due to the conversion of vitamin C into oxalate, which can contribute to stone formation.
