The nurse retrieves hydromorphone "4 mg/mL" from the electronic medication system, for a patient who is receiving hydromorphone 3 mg IM every 6 hours PRN for severe pain. How many mL should the nurse administer to the patient? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The nurse needs to administer hydromorphone 3 mg to the patient. The concentration of the hydromorphone solution is 4 mg/mL. To find out how many mL the nurse should administer, we can use the formula:
The Correct Answer is ["0.8"]
Amount (mg) ÷ Concentration (mg/mL) = Volume (mL)
Step 1: The amount of hydromorphone the patient needs is 3 mg. Step 2: The concentration of the hydromorphone solution is 4 mg/mL. Step 3: Substitute the values into the formula: 3 mg ÷ 4 mg/mL.
Step 4: Calculate the volume: 3 ÷ 4 = 0.75 mL. 0.8 rounded to the nearest tenth

Correct Answer is D
Explanation
The correct answer is choice D. Paper mask and gown.
Choice A rationale:
The stethoscope is not typically placed in a biohazard bag. It is cleaned and disinfected after each use, especially when used with a patient with an infectious disease like MRSA.
Choice B rationale:
Bed linens are usually placed in a designated linen bag, not a biohazard bag, even when the patient has an infectious disease. The linens are then laundered according to the healthcare facility’s infection control guidelines.
Choice C rationale:
A sputum specimen is typically placed in a designated specimen container, not a biohazard bag. The container is then sent to the lab for analysis.
Choice D rationale:
The paper mask and gown used while caring for a patient with MRSA should be placed in a designated biohazard bag before being removed from the room. This is because these items may have come into contact with the bacteria and could potentially spread the infection.
Correct Answer is A
Explanation
Choice A reason: An increased boundary of the wound suggests possible infection or inflammation. C-reactive protein (CRP) is an acute-phase reactant produced by the liver in response to inflammation. A CRP test can help assess the severity of inflammation or infection. The normal range for CRP is generally below 10 mg/L.
Choice B reason: While serum potassium and sodium levels are important electrolytes to monitor, they are not directly related to wound assessment or infection. Normal ranges for potassium are 3.6 to 5.2 mmol/L, and for sodium, 135 to 145 mEq/L.
Choice C reason: Neutrophils are white blood cells that respond to infection. While an elevated neutrophil count can indicate infection, it is not as specific as CRP for inflammation. The normal range for neutrophils is 2,500 to 6,000 cells/mcL.
Choice D reason: Platelets are involved in clotting and would not necessarily change due to wound infection or inflammation. The normal platelet count range is 150,000 to 450,000 platelets/mcL.
