The physician orders Lanoxin elixir 90 mcg PO every morning.
Drug available: Lanoxin elixir 0.05 mg/mL
How many mL will be given?
The Correct Answer is ["1.8"]
First, let's convert 90 mcg to mg:
90 mcg = 0.09 mg
Next, we can use dimensional analysis to calculate the required mL: 0.09 mg Lanoxin x 1 mL/0.05 mg Lanoxin = 1.8 mL
Therefore, the nurse will give 1.8 mL of Lanoxin elixir.
Rounding to the nearest tenth, the answer is 1.8 mL.

Correct Answer is A
Explanation
The correct answer is choice A, low-calorie dense foods. Low-calorie dense foods are those that have fewer calories per unit of volume, such as fruits, vegetables, and lean protein sources. These foods can help the client feel full and satisfied while still consuming fewer calories, which is important for weight loss. High trans fat foods (choice B) and high-glycemic index foods (choice C) should be avoided or limited as they can contribute to weight gain and other health problems. Highcalorie dense foods (choice D) should also be avoided or limited as they can provide too many calories without providing enough nutrients.
Correct Answer is B
Explanation
: Bring a narrow beam of light from the side of the patient's face and briefly shine the light on the pupil, observing the pupil for constriction. This is the appropriate technique to assess pupillary reaction. The nurse should stand to the side of the patient and use a penlight or other focused light source to illuminate one pupil at a time. The light should be directed from the side of the eye, not directly in front of it, to avoid stimulating the accommodation reflex. The nurse should observe for constriction of the pupil, which should occur in response to the light. This assessment is important because changes in pupil size and reactivity can indicate neurological dysfunction or other medical conditions.
