A nurse is providing teaching for a client diagnosed with depression.
Which of the following should the nurse identify as a primary risk factor for this disorder?
Recent history of stressful, positive life events.
Being male and over the age of 80.
Being an only child.
Having elevated levels of serotonin.
The Correct Answer is B
Choice A rationale
A recent history of stressful, positive life events is not a primary risk factor for depression. While any significant life change can trigger stress and potentially contribute to depression, it is typically negative or traumatic events that are most strongly associated with an increased risk of depression.
Choice B rationale
Being male and over the age of 80 is a primary risk factor for depression. Older adults, particularly those with chronic medical conditions, are at an increased risk of depression. Additionally, while women are more likely than men to experience depression at younger ages, the gender gap narrows with age.
Choice C rationale
Being an only child is not a primary risk factor for depression. While family history can play a role in depression risk, it is typically a history of depression in first-degree relatives that is most strongly associated with an increased risk.
Choice D rationale
Having elevated levels of serotonin is not a primary risk factor for depression. In fact, it is typically low levels of serotonin that are associated with an increased risk of depression. Informed consent Explore

Correct Answer is D
Explanation
Choice A rationale
Betamethasone, a corticosteroid, is not known to weaken uterine contractions. It is often administered to pregnant women at risk of preterm delivery to enhance fetal lung maturation and reduce complications associated with prematurity.
Choice B rationale
Betamethasone can potentially increase blood glucose levels, not decrease them. This is particularly relevant in women with gestational diabetes, as corticosteroids can exacerbate hyperglycemia.
Choice C rationale
Betamethasone does not typically decrease the fetal heart rate. Instead, it is used to help mature the lungs of the fetus.
Choice D rationale
Betamethasone is administered to pregnant women at risk of preterm delivery to enhance the production of surfactant in the fetal lungs. Surfactant is a substance that prevents the small air sacs in the lungs from collapsing, thereby aiding in the baby’s ability to breathe after birth.
Correct Answer is B
Explanation
Choice B rationale
The umbilical cord normally contains two arteries and one vein. The arteries carry deoxygenated blood and waste products from the fetus to the placenta, and the vein carries oxygenated blood and nutrients from the placenta to the fetus.
