The physician orders Lanoxin elixir 90 mcg PO every morning.

Drug available: Lanoxin elixir 0.05 mg/mL

How many mL will be given?

Answer and Explanation

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. When conducting a physical assessment of the extremities, the most appropriate assessment would be to assess pulses, capillary refill, strength, edema, skin, and compare with the other extremity. This comprehensive assessment can help to identify potential issues with circulation, strength, and skin integrity, and can also provide a baseline for ongoing assessments. Rebound tenderness in both the arms and legs, skin turgor, and moisture (choice B) are not typically assessed during a physical assessment of the extremities. Assessing the measurements in centimeters of each extremity, pulses, and varicosities (choice C) may be appropriate in certain situations, but it is not a comprehensive assessment of the extremities. Assessing pulses, strength, range of motion, percussion, odor, and edema (choice D) is also not a comprehensive assessment of the extremities and may not provide a complete picture of the client's condition. Therefore, the most appropriate assessment when conducting a physical assessment of the extremities is to assess pulses, capillary refill, strength, edema, skin, and compare with the other extremity.

A. Positive air pressure holds the mouth open. B. Negative pressure holds airways closed. C. Delivery of oxygen facilitates expiratory effort. D. Alternating waves of air stimulate breathing.

Correct Answer is D

Explanation

The correct answer is choice D, alternating waves of air stimulate breathing. CPAP works by delivering a continuous stream of pressurized air through a mask, which is worn over the nose or nose and mouth while sleeping. This air pressure acts like a splint, holding the airway open and preventing it from collapsing during sleep. The alternating waves of air delivered by the CPAP machine help stimulate breathing, keeping the airway open and reducing the number of breathing pauses that occur during sleep. CPAP is a highly effective treatment for obstructive sleep apnea, a condition in which the airway becomes blocked during sleep, leading to breathing pauses and interrupted sleep. By keeping the airway open and stimulating breathing, CPAP helps to improve sleep quality, reduce daytime sleepiness, and improve overall health outcomes in people with sleep apnea.
