A newborn weighs 3400 grams.
The healthcare provider has ordered 0.2 mg/kg of atropine sulfate subcutaneously.
Based on the label below, how much will the nurse administer in mL? (Write in your answer).
The Correct Answer is ["1.7"]
Step 1: 2 mg/kg × 3400 g × (1 kg ÷ 1000 g) = 0.68 mg
Step 2: 68 mg × (1 mL ÷ 0.4 mg) = 1.7 mL.
The nurse will administer 1.7 mL.

Correct Answer is B
Explanation
Choice A rationale
A possible sign of pregnancy includes symptoms that are suggestive but not definitive, such as amenorrhea (absence of menstruation) or fatigue. These signs can have multiple causes and are not conclusive proof of pregnancy.
Choice B rationale
A positive sign of pregnancy includes objective evidence like fetal movement felt by the examiner, fetal heart sounds detected, or visualization of the fetus on ultrasound. These signs provide direct confirmation of pregnancy.
Choice C rationale
Presumptive signs of pregnancy are subjective experiences reported by the patient, such as nausea, breast tenderness, or quickening (feeling fetal movement). These signs are not confirmatory as they can occur in other conditions.
Choice D rationale
Probable signs of pregnancy include objective findings observed by a healthcare provider, such as uterine enlargement, but they are not definitive as they can also be caused by conditions like fibroids.
Correct Answer is A
Explanation
Choice A rationale
50% of the offspring have a chance of developing the disease from the affected parent. Autosomal dominant inheritance means that a single copy of the altered gene in each cell is sufficient to cause the disorder. Thus, each child of an affected parent has a 50% chance of inheriting the condition.
Choice B rationale
Diseases transmitted from a carrier mother to her son typically describe X-linked recessive inheritance, not autosomal dominant. In autosomal dominant conditions, both males and females can be affected, and it doesn't depend on the sex of the parent transmitting the gene.
Choice C rationale
All of the offspring will develop the disease is incorrect. In autosomal dominant inheritance, there is a 50% chance of passing the altered gene to the offspring, not 100%.
Choice D rationale
50% of the offspring will be carriers of the disease from the affected parent is incorrect for autosomal dominant inheritance. There are no "carriers" in autosomal dominant diseases; individuals either have the disease or they don't, based on whether they inherit the altered gene.
