A nurse is preparing to administer vitamin K 1mg IM to a newborn.
Available is vitamin K injection 1 mg/0.5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth.
Use a leading zero if it applies.
Do not use a trailing zero.).
0.5
1.0
2.0
0.6
The Correct Answer is A
Choice A rationale:
To calculate the amount of vitamin K (1 mg) to administer, you need to use the given concentration (1 mg/0.5 mL). This means that 1 mg is present in every 0.5 mL of the solution. To determine how many milliliters (mL) you should administer to get 1 mg, you can set up a proportion: 1 mg / X mL = 1 mg / 0.5 mL Cross-multiply and solve for X: X = (1 mg * 0.5 mL) / 1 mg X = 0.5 mL Therefore, the nurse should administer 0.5 mL, which can be rounded to 2.0 mL to the nearest tenth of a milliliter. Now, let's move on to the next question.

Correct Answer is D
Explanation
The correct answer is choice d. Use a postpartum depression-screening tool with the client.
Choice A rationale:
Arranging for counseling is important for long-term support, but the first step is to accurately assess the client’s condition using a screening tool.
Choice B rationale:
Requesting a prescription for an antidepressant may be necessary, but it should follow a proper assessment and diagnosis.
Choice C rationale:
Reinforcing teaching about rest and sleep is beneficial, but it does not address the immediate need to assess the severity of the client’s symptoms.
Choice D rationale:
Using a postpartum depression-screening tool is the first step to identify the severity of the client’s symptoms and determine the appropriate course of action.
Correct Answer is A
Explanation
Choice B rationale:
"I'll expect the penis to heal within 24 hours" is not an accurate understanding of circumcision care. Circumcision healing typically takes longer than 24 hours, and this statement could lead to unrealistic expectations. It's essential for the parent to understand that healing may take several days to a week, and they should watch for signs of infection or other complications.
Choice C rationale:
"I'll make sure his diaper is loose in the front" is not directly related to circumcision care. While keeping the diaper loose can help prevent irritation and discomfort, it does not address specific care for the circumcision site. This statement does not demonstrate an understanding of the key points of circumcision care.
Choice D rationale:
"I'll apply alcohol swab to his penis during diaper changes" is not recommended for circumcision care. Using alcohol swabs can be too harsh on the sensitive skin of a newborn and may lead to irritation. It's generally advised to clean the area with warm water and mild soap or simply allow it to air dry.
Choice E rationale:
"I wash his penis with warm water and mild soap each day" is a correct understanding of circumcision care. Keeping the circumcision site clean with warm water and mild soap is a recommended practice to prevent infection. However, it's important to avoid vigorous scrubbing or excessive cleaning, as this can also cause irritation.
