A client who had a knee replacement surgery receives a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL prefilled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.)
The Correct Answer is ["0.6"]
- Medication dose: 30 mg enoxaparin
- Medication concentration: 30 mg per 0.3 mL (prefilled syringe)
- Frequency: Every 12 hours
- Duration: 10 days
Calculation:
- Injections per day: Since the medication is given every 12 hours, the client will receive injections 2 times per day (24 hours / 12 hours/injection).
- Total medication per day: To find the total amount of enoxaparin needed per day, multiply the single injection dose by the number of injections:
Total enoxaparin/day = Dose per injection x Number of injections/day = 30 mg/injection x 2 injections/day = 60 mg/day
- Volume of medication per day: Now, we need to find the volume of solution needed to deliver the total daily dose (60 mg) based on the medication concentration (30 mg/0.3 mL). We can achieve this with a proportion:
Volume (mL) / Total dose (mg) = Concentration (mg/mL)
Volume (mL) = (Total dose (mg) x Concentration (mL/mg)) / Concentration (mg/mL)
Plugging in the values:
Volume (mL) = (60 mg x 0.3 mL/mg) / 30 mg/mL
Volume (mL) = 18 mL / 30 mL/mL
Simplifying:
Volume (mL) = 0.6 mL
Therefore, the practical nurse (PN) should administer 0.6 mL of enoxaparin each day.

Correct Answer is ["B","D","E"]
Explanation
A. Bacterial conjunctivitis is not a reportable infectious disease according to the CDC. While it is a common condition, it does not fall under the mandatory reporting requirements for public health.
B. Diphtheria is a reportable disease because it is a severe bacterial infection that can lead to outbreaks and severe health consequences. Reporting helps track and control the spread of this potentially life-threatening disease.
C. Pediculosis (head lice) is not a reportable disease by the CDC. It is a common parasitic infestation but does not require mandatory reporting for public health surveillance.
D. Anthrax is a reportable disease due to its potential for severe illness and its use as a bioterrorism agent. Reporting anthrax is crucial for monitoring and managing outbreaks and potential public health threats.
E. Tuberculosis is a reportable disease because it is a serious infectious disease that can spread in communities and requires public health measures to manage and prevent outbreaks.
Correct Answer is ["A","D","E"]
Explanation
A. Place the drink where the client can reach from her bed
Placing the drink where the client can easily reach it encourages regular fluid intake. Accessibility is key for clients who may be feeling weak or fatigued, especially when dealing with symptoms of illness like fever and cough. Ensuring that fluids are within reach minimizes barriers to drinking and supports better hydration efforts.
B. Encourage drinks with high sugar content
Drinks with high sugar content are not ideal for promoting adequate fluid intake. High sugar content can worsen symptoms like nausea or dehydration and may lead to increased thirst or gastrointestinal upset, which is counterproductive to encouraging fluid intake. Offering fluids with balanced electrolytes and moderate sugar content is more beneficial.
C. Only offer water or other clear drink
Offering only water or clear drinks can be too restrictive and may not meet the client's preferences or needs. While clear liquids are appropriate, incorporating a variety of fluids can improve hydration and patient satisfaction. It is beneficial to offer options that the client might find appealing.
D. Ask the client what her favorite drink is
Asking the client for her favorite drink engages her in the decision-making process and increases the likelihood of her consuming more fluids. Personal preferences can significantly affect fluid intake, and offering drinks she likes can help in achieving adequate hydration.
E. Offer both hot and cold drinks
Offering both hot and cold drinks can cater to the client’s preferences and provide comfort, which may encourage her to drink more fluids. Variety in temperature can make drinking fluids more appealing, especially if the client is feeling unwell or has specific preferences.
F. Suggest popular drinks like coffee or soda
Suggesting coffee or soda is not recommended due to their diuretic effects and potential for dehydration. Coffee and soda can also interfere with electrolyte balance and are generally not suitable for hydration in a clinical setting where the goal is to address fluid volume deficit
