A nurse is preparing to administer ceftriaxone 200 mg IM. How many mL should the nurse administer? (TYPE NUMBERS ONLY. Round to the nearest hundredth. Use a leading zero if necessary. Do not use trailing zeros.)
The Correct Answer is ["0.57"]
Identify the desired dose: 200 mg
Identify the available concentration for IM administration: The package insert information states that "Each 1 mL of solution contains approximately 350 mg equivalent of ceftriaxone." So, the available concentration is 350 mg/mL.
Calculate the volume to administer (mL):
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 200 mg / 350 mg/mL
= 0.5714... mL
Round the answer to the nearest hundredth:
= 0.57 mL

Correct Answer is D
Explanation
A. Apply supplemental oxygen by face mask as needed: While oxygen therapy may be necessary for a client with pneumonia, it is a treatment intervention rather than an assessment activity. The nurse must first gather assessment data before deciding on interventions.
B. Document "impaired oxygenation" on the nursing care plan: This pertains to the diagnosis and planning phase of the nursing process. It is based on assessment findings and does not constitute an assessment activity in itself.
C. Collaborate with the client to form goals: This is part of the planning phase and involves setting mutually agreed-upon outcomes, which occurs after the assessment has been conducted.
D. Auscultate the chest for breath sounds: By listening to the lung fields, the nurse can detect abnormal sounds such as crackles or diminished breath sounds, which are commonly associated with pneumonia. This provides critical information about respiratory status and helps guide further care.
Correct Answer is A
Explanation
A. Obtain a new sterile dressing kit: If the patient touches sterile supplies, contamination has occurred, compromising the sterile field. To prevent infection, the nurse must discard the contaminated kit and use a new sterile dressing kit.
B. Wash the patient's hands: Washing hands improves hygiene but doesn’t re-sterilize already contaminated items. The dressing kit is no longer sterile, so washing hands alone is insufficient. Sterility must be restored with new supplies.
C. Continue changing the dressing: Proceeding with the contaminated supplies risks introducing pathogens into the wound, increasing infection risk. The sterile field must be maintained at all times.
D. Restrain the patient's hands: Restraining without assessing or explaining is not appropriate; it can cause distress and is not a first-line response to contamination during a sterile procedure.
