A nurse is preparing to administer diazepam 2 mg twice daily via NG tube. Available is diazepam oral solution 5 mg/1 mL. How many mL should the nurse administer with each dose?
0.4 mL.
0.8 mL.
1 mL.
1.6 mL.
The Correct Answer is A
To calculate how many milliliters (mL) of diazepam oral solution should be administered, you can use the following formula:
Dose (mL) = Desired dose (mg) / Concentration (mg/mL)
In this case, the desired dose is 2 mg, and the concentration of the diazepam oral solution is 5 mg/1 mL.
Dose (mL) = 2 mg / 5 mg/mL = 0.4 mL
So, the nurse should administer 0.4 mL of diazepam oral solution with each dose. The correct answer is:
A) 0.4 mL.

Correct Answer is D
Explanation
Choice A rationale:
Dysrhythmia refers to irregular heart rhythms and is not associated with the carotid artery. It involves issues with the heart's electrical conduction system.
Choice B rationale:
A cardiac murmur is an abnormal sound heard during the heartbeat cycle, usually indicating turbulent blood flow across heart valves. It's not directly related to the carotid artery.
Choice C rationale:
Hypotension refers to low blood pressure, which might impact blood flow through the carotid artery but wouldn't directly cause the sound known as a bruit.
Choice D rationale:
A bruit heard while auscultating the carotid artery suggests a narrowed arterial lumen. A bruit is a whooshing or blowing sound caused by turbulent blood flow due to arterial narrowing or blockage.
Correct Answer is C
Explanation
Choice A rationale:
The walking gait test is used to assess a client's walking pattern and balance, particularly for identifying abnormalities in gait. However, it doesn't specifically evaluate sensory functions, making it an inappropriate choice for this scenario.
Choice B rationale:
The plantar reflex test, also known as the Babinski reflex test, assesses the neurological integrity of the corticospinal tract. It involves stimulating the sole of the foot to elicit specific reflex movements. While this test is important in assessing neurological function, it doesn't directly evaluate sensory functions as requested in the question.
Choice C rationale:
The finger-to-nose test is a part of the neurological examination used to assess a client's coordination and proprioception. In this test, the client is asked to touch their nose with their index finger while alternating between eyes closed and eyes open. This evaluates their ability to sense the position of their limbs in space (proprioception) and their coordination. It directly addresses the focus of the question, making it the correct choice.
Choice D rationale:
The Romberg test evaluates a client's balance and proprioception. It involves having the client stand with their feet together and their eyes closed to assess their ability to maintain balance without visual input. While this test is relevant to sensory functions, it primarily assesses proprioception and balance rather than coordination, which the question is specifically targeting.
