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 ["A","C","D","E"]

Explanation

A. Rotavirus (RV): Rotavirus vaccine is routinely recommended for infants to protect against rotavirus infection, which can cause severe diarrhea and dehydration in young children. It is typically administered orally in multiple doses starting at around 2 months of age.
B. Human papillomavirus (HPV): The HPV vaccine is not routinely administered to infants at 1 year of age. It is typically recommended for preteens and adolescents to protect against HPV-related cancers and genital warts.
C. Measles, mumps rubella (MMR): The MMR vaccine is routinely given to infants around 1 year of age to protect against measles, mumps, and rubella (German measles). It is typically administered as a single injection.
D. Varicella (VAR): The varicella vaccine is routinely recommended for infants to protect against chickenpox (varicella) infection. It is typically administered as a single injection around 1 year of age.
E. Diphtheria, tetanus and acellular pertussis (DTaP): The DTaP vaccine is routinely given to infants to protect against diphtheria, tetanus, and pertussis (whooping cough). It is typically administered as a series of injections starting at around 2 months of age.

A. Blood B. Parasites C. Steatorrhea D. Bacteria

Correct Answer is A

Explanation

A. Blood: The purpose of a stool guaiac test is to detect the presence of occult (hidden) blood in the stool. This test is commonly used to screen for gastrointestinal bleeding, which may indicate various conditions such as peptic ulcers, colorectal cancer, inflammatory bowel disease, or hemorrhoids. The guaiac test relies on the chemical reaction between guaiac resin and the heme component of hemoglobin in blood, resulting in a color change when blood is present in the stool.
B. Parasites: Stool tests for parasites typically involve examining stool samples under a microscope to identify the presence of parasitic organisms, such as protozoa or helminths. These tests are used to diagnose parasitic infections, such as giardiasis, cryptosporidiosis, or intestinal worms, rather than detecting blood in the stool.
C. Steatorrhea: Stool tests for steatorrhea assess the presence of excess fat in the stool, which may indicate malabsorption disorders, pancreatic insufficiency, or other gastrointestinal conditions affecting fat digestion and absorption. These tests involve analyzing stool samples for the presence of undigested fat globules rather than detecting blood.
D. Bacteria: Stool cultures are used to detect the presence of pathogenic bacteria in the stool, which may indicate bacterial infections such as Salmonella, Shigella, or Campylobacter. These tests involve culturing stool samples on specific media to identify bacterial pathogens rather than detecting blood. Stool guaiac tests specifically target the detection of occult blood and are not designed to identify bacteria in the stool.
