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. Lower the patient back to the side of the bed, pivot her back into the bed, and assess the patient's vital signs. When a patient reports feeling faint while attempting to stand, it is important to take immediate action to prevent a fall and ensure patient safety. Lowering the patient back to the bed will help prevent injury in case of a fall. Then, the nurse should pivot the patient back into the bed slowly and safely. Once the patient is lying down, assess the vital signs, particularly the blood pressure and heart rate, to ensure that the patient is stable. This information can help the nurse determine if the patient is experiencing postural hypotension or other complications from surgery. After assessing the vital signs, the nurse can report the findings to the healthcare provider and implement appropriate interventions to help prevent future episodes of fainting.
Correct Answer is ["B","C","D"]
Explanation
The correct answer is choices B, C, and D.
When assessing respiratory rate, it is important to count for a full respiratory cycle, which includes both inhalation and exhalation. If the respiratory rate is regular, the nurse can count for 30 seconds and multiply by 2 to obtain the total number of breaths per minute. The nurse should also observe the depth and rhythm of the respirations, noting any abnormalities or changes. It is not recommended to pretend to take the radial pulse while assessing respiratory rate, as this can lead to inaccurate readings and is not a professional approach to care
