The healthcare provider prescribes diazepam 8 mg IM every 4 hours PRN muscle spasms for a client with a fractured femur. The available vial is labeled, "Diazepam Injection, USP 10 mg/2 mL" How many mL should the nurse administer to the client? (Enter numerical value only. If rounding is required round to the nearest tenth)
The Correct Answer is ["1.6"]
To determine how many milliliters (mL) of diazepam the nurse should administer to the client, first, we need to calculate the amount of medication needed for each dose.
The prescribed dose is 8 mg of diazepam.
Volume= Desired dose/available concentration per ml
Available concentration per ml= 10mg/2ml Available concentration per ml= 5mg/ml Volume= 8mg/5mg per ml
Volume= 1.6ml
So, the nurse should administer 1.6 mL of diazepam to the client.

Correct Answer is C
Explanation
C. Peptic ulcer disease involves the formation of open sores in the lining of the stomach or the duodenum. The characteristic symptom of PUD is abdominal pain, typically located in the upper mid abdomen. This pain is often described as gnawing, burning, or aching in nature. The pain may occur shortly after eating, especially when the stomach is empty (gastric ulcer), or it may occur 2-3 hours after eating, typically at night (duodenal ulcer).
A. describes symptoms more suggestive of irritable bowel syndrome (IBS) or gastrointestinal sensitivity to spicy foods, leading to cramps and diarrhea, but it is less specific to PUD.
B. indicates frequent use of antacids for indigestion, which may suggest symptoms of acid reflux or gastritis but do not specifically point to the presence of peptic ulcers.
D. suggests more severe systemic issues such as malignancy or chronic diseases rather than solely PUD.
Correct Answer is A
Explanation
A. This choice involves culturing a sputum sample collected from the patient to identify the presence of Mycobacterium tuberculosis, the bacterium that causes tuberculosis. A positive result confirms the diagnosis of TB.
B. Hemoccult tests are used to detect hidden (occult) blood in stool samples. While hemoptysis (coughing up blood) can be a symptom of TB, a hemoccult test is not specific for TB diagnosis. It is more commonly used in detecting gastrointestinal bleeding.
C. Imaging studies like chest x-ray or CT scans can reveal abnormalities in the lungs suggestive of TB, such as infiltrates, cavitations, or lymph node enlargement. While these tests can support the diagnosis, they are not definitive on their own.
D. The PPD skin test is a common screening tool for TB exposure. It detects the presence of a delayed hypersensitivity reaction to proteins derived from Mycobacterium tuberculosis. A positive PPD indicates exposure to TB but does not confirm active disease.
