The practical nurse (PN) is preparing the prescribed dose of diazepam 5 mg IM STAT for a client in delirium tremens. The available concentration is 10 mg/2mL. How many milliliters should the PM administer to the client? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.0"]
Identify the prescribed dose and the available concentration.
Prescribed dose = 5 mg
Available concentration = 10 mg per 2 mL
Calculate the volume in milliliters (mL) to administer.
Volume (mL) = (Prescribed dose (mg) / Available concentration (mg)) x Available volume (mL)
= (5 mg / 10 mg) x 2 mL
= 0.5 x 2 mL
= 1.0 mL.

Correct Answer is C
Explanation
A. On the same side as the affected extremity: Placing the cane on the affected side reduces stability because the weaker side does not provide sufficient support. This increases the risk of falls and improper gait.
B. Approximately one foot away from the body to stabilize balance: Holding the cane too far from the body can compromise balance and coordination. Proper cane placement should maintain stability close to the body while allowing natural movement.
C. On the opposite side of the affected extremity: The cane should be held on the side opposite the weaker or affected limb. This provides optimal support and balance during ambulation, allowing the client to bear weight safely while stepping forward with the affected leg.
D. In front of the body to lean on while stepping forward: Leaning on the cane excessively shifts weight forward and can destabilize the client. The cane is intended to provide lateral support rather than function as a crutch for leaning.
Correct Answer is D
Explanation
A. Document the client's loss of memory in the record: Documentation is important, but it is not the first or only action needed when a new onset of confusion is observed. The PN should first provide orientation and supportive interventions before recording findings.
B. Encourage the client to rest during the day: While adequate rest is beneficial, excessive daytime sleep can worsen confusion, especially in new environments. Promoting normal sleep–wake cycles is more effective than simply encouraging daytime rest.
C. Notify the family of the change in the client's condition: Informing the family may be appropriate if confusion persists or worsens, but the priority is to support and reorient the client directly. Immediate family notification is not necessary for mild, situational disorientation.
D. Remind the client what day of the week it is: Gentle reorientation helps reduce confusion and anxiety commonly seen with relocation or unfamiliar surroundings. Providing frequent orientation cues supports cognitive function and adjustment in newly admitted older adults.
