A nurse is preparing to infuse 1 liter of 0.9% sodium chloride IV over 8 hr with a tubing set that delivers 15 gtts/mL. The nurse should set the manual IV infusion to deliver how many drops/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 ["31"]
The correct answer is 31 gtts/min. To calculate the infusion rate, the nurse should use the following formula:
Infusion rate (gtts/min) = Volume (mL) x Drop factor (gtts/mL) / Time (min)
Plugging in the given values, we get:
Infusion rate (gtts/min) = 1000 mL x 15 gtts/mL / 480 min
Infusion rate (gtts/min) = 31.25 gtts/min
Rounding to the nearest whole number, we get 31 gtts/min.

Correct Answer is B
Explanation
Choice A: Striae gravidarum are stretch marks that appear on the abdomen, breasts, or thighs during pregnancy. They are caused by the tearing of the connective tissue in the dermis due to rapid growth or weight gain.
Choice B: Linea nigra is a dark vertical line that runs from the umbilicus to the pubic area. It is caused by increased melanin production due to hormonal changes during pregnancy. This is the correct choice because it matches the description in the question.
Choice C: Vascular spiders are dilated blood vessels that appear on the skin as red or purple spider-like lesions. They are caused by increased estrogen levels and blood volume during pregnancy. They are usually found on the face, neck, chest, or arms.
Choice D: Melasma is a condition that causes brown or gray patches on the face, especially on the forehead, cheeks, nose, or upper lip. It is caused by increased melanin production due to sun exposure and hormonal changes during pregnancy. It is also known as chloasma or the mask of pregnancy.
Correct Answer is B
Explanation
Choice A Reason: This is incorrect because ambivalence is a mixed or contradictory feeling towards something or someone. It may occur in some women during pregnancy, especially if the pregnancy was unplanned or unwanted. However, it is not the most likely emotional response in the first trimester.
Choice B Reason: This is correct because emotional lability is a rapid and exaggerated change in mood or affect. It may occur in many women during pregnancy due to hormonal fluctuations, physical changes, and psychological stressors. Emotional lability may manifest as increased irritability, anxiety, sadness, or crying spells.
Choice C Reason: This is incorrect because introversion is a personality trait that indicates a preference for solitude and inward focus. It may be present in some women before or during pregnancy, but it is not an emotional response that is specific to the first trimester.
Choice D Reason: This is incorrect because acceptance is a positive attitude that indicates a willingness to embrace the reality of something or someone. It may develop in some women during pregnancy as they adjust to their new role and identity as mothers. However, it is not the most likely emotional response in the first trimester.
