The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. Total volume after reconstitution is 2.5 mL. After reconstitution, how many mL should be administered to the client? (Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).
The Correct Answer is ["1"]
This is the correct answer because the concentration of cefazolin after reconstitution is 1 gram/2.5 mL, which is equivalent to 400 mg/1 mL. Therefore, to administer 400 mg of cefazolin, the PN should draw up 1 mL of the reconstituted solution. This can be calculated using the formula:
Desired dose / Available dose = Volume to administer
400 mg / 1000 mg = x mL / 2.5 mL
x = (400 x 2.5) / 1000
x = 1 mL

Correct Answer is ["A","B","C","H"]
Explanation
Choice A rationale:
A Speech Therapist is crucial in this case. The patient presented with garbled speech, which indicates a possible speech impairment. A speech therapist can evaluate the patient’s speech and language skills and provide therapy to improve any deficits, which can significantly enhance the patient’s quality of life.
Choice B rationale:
A Case Manager is essential in coordinating the patient’s care. They ensure that the patient’s healthcare needs are met and that the patient is receiving appropriate treatments. They also coordinate with various healthcare professionals and may assist with insurance issues or discharge planning.
Choice C rationale:
A Physical Therapist can help the patient regain physical strength and mobility that might have been affected by the stroke. They can provide exercises and treatments to improve balance, coordination, and muscle strength, which can help the patient regain independence in their daily activities.
Choice D rationale:
A Pharmacy Technician is not typically involved in direct patient care or recovery. Their role is more focused on assisting pharmacists with dispensing medication and other administrative tasks in a pharmacy setting.
Choice E rationale:
The Chief Nursing Officer (CNO) is a high-level executive role that oversees nursing staff across an entire healthcare organization. While they play a crucial role in ensuring quality nursing care, they would not be directly involved in individual patient recovery.
Choice F rationale:
A Respiratory Therapist could be helpful if the patient had respiratory issues or complications related to the stroke, but given the information provided, it does not appear that respiratory therapy is needed in this case.
Choice G rationale:
A Medical Assistant typically performs administrative and clinical tasks in healthcare settings but does not specialize in rehabilitation or recovery care for stroke patients.
Choice H rationale:
An Occupational Therapist is vital for stroke recovery. They can help the patient regain skills needed for daily living activities that might have been affected by the stroke, such as eating, dressing, and bathing. They can also provide strategies to compensate for any lasting deficits from the stroke. In summary, for a comprehensive recovery plan for this patient who has had a stroke, an interdisciplinary team involving a Speech Therapist (A), Case Manager (B), Physical Therapist ©, and Occupational Therapist (H) would be most beneficial.
Correct Answer is D
Explanation
Choice A rationale:
An altered level of consciousness is not a typical finding in Alzheimer's disease. This condition is characterized by cognitive decline and memory impairment, but consciousness itself is not directly affected.
Choice B rationale:
Rapid mood swings can occur in individuals with Alzheimer's disease due to the changes in brain structure and function. These mood swings are a common behavioral symptom. However, the more distinctive hallmark of Alzheimer's disease is the cognitive decline rather than mood swings.
Choice C rationale:
Excessive motor activity is not a prominent feature of Alzheimer's disease. Instead, individuals with Alzheimer's disease often experience a decline in motor skills and coordination as the disease progresses.
Choice D rationale:
Failure to recognize familiar objects is a common symptom of Alzheimer's disease. This is referred to as agnosia, where individuals may struggle to recognize familiar people, objects, or places. It results from the progressive damage to brain regions responsible for memory and sensory processing.
