A nurse is preparing to administer 1 mg vitamin K to a newborn. The medication is available in 1 mg/0.5 mL. How much should the nurse administer?
(Round to the nearest tenth. Use a leading zero when applicable. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
Step 1: Determine the dosage required. Required dosage = 1 mg
Step 2: Determine the concentration of the available solution. Available concentration = 1 mg/0.5 mL
Step 3: Calculate the volume to be administered. Volume to be administered = Required dosage ÷ Available concentration Volume to be administered = 1 mg ÷ (1 mg ÷ 0.5 mL)
Step 4: Perform the division. 1 ÷ (1 ÷ 0.5) = 1 ÷ 2 = 0.5
Step 5: Round the answer to the nearest tenth. Rounded volume = 0.5 mL
The nurse should administer 0.5 mL.

Correct Answer is D
Explanation
Choice A reason:
Handrails are present in the bathroom: Handrails in the bathroom are actually a safety feature, not a risk. They provide support and stability, helping to prevent falls, especially for individuals with decreased vision or mobility issues.
Choice B reason:
Electrical cords are placed along the walls: Electrical cords placed along the walls can pose a tripping hazard, particularly for someone with decreased vision. However, if they are secured properly and not in walkways, the risk can be minimized.
Choice C reason:
Uses a microwave for cooking: Using a microwave for cooking is generally safe and convenient for older adults, especially those with decreased vision. It reduces the risk of burns and fires compared to using a stove.
Choice D reason:
Scatter rugs are present in the kitchen: Scatter rugs are a significant safety risk for older adults, particularly those with decreased vision. They can easily cause tripping and falls, which can lead to serious injuries. It is recommended to remove scatter rugs or ensure they are non-slip and securely fastened.

Correct Answer is A,B,C,D,E
Explanation
1. a) Inspect the abdomen for skin integrity: The first step in an abdominal assessment is inspection. The nurse should visually examine the abdomen for any abnormalities such as skin changes, scars, distention, or masses.
2. b) Ask the client about having a history of abdominal pain: Gathering a history of abdominal pain is crucial as it provides context for the physical findings. This step helps identify any underlying conditions that may influence the assessment.
3. c) Auscultate the abdomen for bowel sounds: Auscultation should be performed before palpation and percussion to avoid altering the bowel sounds. The nurse listens for the presence, frequency, and character of bowel sounds in all four quadrants.
4. d) Percuss the abdomen in each of the four quadrants: Percussion helps to assess the presence of fluid, air, or masses in the abdomen. The nurse taps on the abdomen to listen for sounds that indicate the underlying structures.
5. e) Palpate the abdomen gently for tenderness: Palpation is the final step and involves gently pressing on the abdomen to check for tenderness, masses, or organ enlargement. This step should be done last to avoid causing discomfort or altering the findings of the other steps.
