A community health nurse is teaching a group of older adults about risk factors for a hip fracture.
What statements indicate a correct understanding of these risk factors? Select all that apply.
“Men are more at risk for hip fractures than women.”.
“A history of osteoporosis is a risk factor.”.
“An increase in estrogen will weaken my bones.”.
“I am prone to a hip fracture if I’ve fallen in the past.”.
“I am more at risk as I get older.”.
Correct Answer : B,D,E
Choice A is wrong because women are more at risk for hip fractures than men.
This is partly because women lose bone density faster than men do, especially after menopause.
Choice C is wrong because an increase in estrogen will not weaken the bones. In fact, estrogen helps protect the bones from osteoporosis, which is a leading cause of hip fracture.
Some other risk factors for hip fracture include:
- Excessive alcohol and caffeine consumption
- Lack of physical activity
- Low body weight
- Tall stature
- Vision problems
- Dementia
- Medications that cause bone loss
- Cigarette smoking
- Institutional living, such as an assisted-care facility
- Increased risk for falls, related to conditions such as weakness, disability, or unsteady gait
Normal ranges for bone density vary by age and sex, but generally, a T-score of -1.0 or above is considered normal, while a T-score of -2.5 or below is considered osteoporotic. A T-score between -1.0 and -2.5 is considered osteopenic, which means low bone mass.

Correct Answer is D
Explanation
The question asks how many milligrams of the medication will be in 1 mL of D5W. To find this, we need to know the concentration of the medication in the solution.
Concentration is the amount of medication per unit volume of solution. We can use this formula:
Concentration = Mass / Volume
We know that 250 mg of the medication is diluted in 500 mL of D5W. So we can plug these values into the formula:
Concentration = 250 mg / 500 mL Simplifying, we get:
Concentration = 0.5 mg / mL
This means that there are 0.5 mg of the medication in every 1 mL of D5W. So the answer is
- To check our answer, we can use another formula:
Mass = Concentration x Volume
If we want to find the mass of the medication in 1 mL of D5W, we can multiply the concentration by the volume:
Mass = 0.5 mg / mL x 1 mL Simplifying, we get:
Mass = 0.5 mg
This matches our answer.
The other choices are wrong because they do not use the correct formula or values. Here is why:
Choice A is wrong because it uses the inverse of the concentration (1 / 0.5) instead of the concentration (0.5).
Choice B is wrong because it uses the mass of the medication (250 mg) instead of the concentration (0.5 mg / mL).
Correct Answer is B
Explanation
Interview the client privately and ask if anyone is harming her.
This is because the nurse has a duty to assess the client for possible elder abuse and report any suspicions to the appropriate authorities.
The nurse should not assume that the son is the abuser or that the client will disclose the abuse without being asked directly.
The nurse should also respect the client’s autonomy and privacy and not confront the son or provide an elder abuse brochure without the client’s consent.
Choice A is wrong because it may imply that the client is responsible for preventing the abuse or that the nurse has already made a judgment about the situation.
It may also be ineffective if the client is unable or unwilling to read the brochure or seek help. Choice C is wrong because it may delay the assessment and intervention for the client.
It may also be biased and unfair to observe the son without interviewing him or the client first.
Choice D is wrong because it may violate the client’s rights and preferences.
It may also be premature to report the abuse without confirming it with the client or obtaining more evidence.
