A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 mg/mL How many mL should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.2"]

To calculate the volume of morphine sulfate to administer, we can use the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Plugging in the known values:

Dose = 2 mg
Concentration = 10 mg/mL

Volume (mL) = 2 mg / 10 mg/mL

Volume (mL) = 0.2 mL

Therefore, the nurse should administer 0.2 mL of morphine sulfate per dose.

Rounded to the nearest tenth: 0.2 mL

Correct Answer is ["0.5"]

Explanation

Let's convert the digoxin dosage from mcg (micrograms) to mg (milligrams) and then divide it by the amount of digoxin per tablet to find out how many tablets are needed.

Steps to solve:

Convert digoxin dose from mcg to mg:
- We know 1 mg is equal to 1000 mcg.
- Digoxin dose (mg) = Digoxin dose (mcg) / 1000 mcg/mg
- Digoxin dose (mg) = 125 mcg / 1000 mcg/mg
- Digoxin dose (mg) = 0.125 mg
Calculate the number of tablets required:
- Number of tablets = Digoxin dose (mg) / Digoxin per tablet (mg)
- Number of tablets = 0.125 mg / 0.25 mg/tablet

Since the result is 0.5, we need to round to the nearest tenth.

Answer: The nurse should administer 0.5 tablets per dose.

A. "My child was born with a birth defect due to an exposure I had overseas" B. "In my dreams, all I can see are the wounded reaching out and trying to grab me" C. "I check any rooms enter because the enemy is still after me and could be hiding anywhere" D. "I killed four enemy soldiers with my bare hands and saved my entire battalion"

Correct Answer is C

Explanation

A. This statement reflects guilt or concern over potential harm to the child, which may be distressing but does not specifically indicate symptoms of PTSD related to combat exposure.
B. This statement describes nightmares or intrusive thoughts related to traumatic events, which are common symptoms of PTSD. The content of the dreams suggests re-experiencing of traumatic events, which is characteristic of PTSD.
C. This statement reflects hypervigilance and paranoia, common symptoms of PTSD. The client's behavior of checking rooms for potential threats indicates a heightened state of arousal and persistent fear related to past combat experiences.
D. While involvement in combat and actions such as killing enemy soldiers may contribute to the development of PTSD, this statement does not directly reflect symptoms of the disorder. Instead, it describes a specific event from the client's military experience. Symptoms of PTSD typically involve re-experiencing, avoidance, negative changes in mood and cognition, and hyperarousal.
