A health care provider prescribes 50 mg of a drug. The drug is only available in a 20 mL vial that contains 20 mg/mL of the drug. How much solution must the nurse administer for each dose?
The Correct Answer is ["2.5"]
To calculate the amount of solution needed for each dose, we need to use the formula:
Amount of solution (mL) = Dose (mg) / Concentration (mg/mL)
Plugging in the given values, we get:
Amount of solution (mL) = 50 mg / 20 mg/mL
Simplifying, we get:
Amount of solution (mL) = 2.5 mL
Therefore, the nurse must administer 2.5 mL of the solution for each dose.

Correct Answer is ["A","C","E"]
Explanation
A. Bradycardia
Bradycardia (slow heart rate) is a symptom of cholinergic crisis. Excessive stimulation of acetylcholine receptors can lead to bradycardia.
B. Rash
Rash is not typically associated with cholinergic crisis. Instead, it may be associated with other conditions or drug reactions.
C. Vomiting
Vomiting is a symptom of cholinergic crisis. Excessive stimulation of the gastrointestinal tract by acetylcholine can lead to increased gastrointestinal motility and nausea/vomiting.
D. Fever
Fever is not typically associated with cholinergic crisis. Instead, it may suggest an infection or other inflammatory condition.
E. Drooling
Drooling is a symptom of cholinergic crisis. Excessive stimulation of salivary glands by acetylcholine can lead to increased salivation and drooling.
Correct Answer is C
Explanation
A. Blood cultures will need to be drawn.
Blood cultures are not typically used for diagnosing H. pylori infection. Instead, specific blood tests, such as serology or antibody tests, may be employed to detect antibodies against H. pylori.
B. A biopsy of the stomach will be done.
While a biopsy may be taken during an upper endoscopy to examine the stomach lining for ulcers and H. pylori infection, it is not the primary method for detecting the presence of H. pylori. The biopsy may be used for confirming the infection and assessing the severity of damage.
C. A breath test will be performed.
This is the correct choice. The breath test is a common and non-invasive method used to detect the presence of H. pylori. The patient drinks a solution containing a substance that H. pylori can break down, and the detection of carbon dioxide in the patient's breath indicates the presence of the bacteria.
D. Computerized scanning will identify if H. pylori is present.
Computerized scanning, such as computed tomography (CT) scans, is not a primary method for detecting H. pylori. Imaging studies are not typically used for H. pylori diagnosis, and the methods mentioned earlier, like breath tests and endoscopy, are more commonly employed.
