The physician orders 500 mg PO of medication. The Medication is supplied as a suspension 125 mg/5mL. How many mL will the nurse administer for one dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Tizanidine is a sleep aid and used to promote sleep along with melatonin:

This is incorrect. Tizanidine is not classified as a sleep aid. While muscle relaxants like tizanidine may cause drowsiness as a side effect, its primary purpose is to reduce muscle spasms rather than to promote sleep. Using it in combination with melatonin for sleep would not be appropriate unless specifically prescribed by a healthcare provider.

B. Tizanidine is a muscle relaxant medication used to reduce muscle spasms:

Tizanidine is a centrally acting muscle relaxant that is commonly used to treat muscle spasms and spasticity. In clients with amyotrophic lateral sclerosis (ALS), spasticity can be a significant symptom, leading to muscle stiffness and discomfort. Tizanidine helps by relaxing the muscles and alleviating the muscle tightness associated with ALS. It works by inhibiting nerve impulses that cause muscles to contract, thus reducing spasticity and improving mobility. This medication is not intended for sleep promotion or pain relief directly, but rather to manage muscle spasms.

C. Tizanidine is an antibiotic medication used to treat bacterial infections:

This is incorrect. Tizanidine is not an antibiotic and has no role in treating bacterial infections. It is a muscle relaxant used for managing spasticity, not an antimicrobial drug.

D. Tizanidine is an opiate and is used to relieve severe pain:

This is incorrect. Tizanidine is not an opiate and does not belong to the class of opioids. It does not have the pain-relieving effects of opioid analgesics. While it may provide some relief from muscle discomfort, it is not used to treat severe pain in the way opiates like morphine or oxycodone are. Tizanidine’s primary purpose is to address muscle spasticity, not pain management.

A. Hand washing before and after client contact: The most important infection control guideline when caring for a client with acute respiratory distress syndrome (ARDS) who is on a ventilator is hand hygiene. This is because ventilated patients are at high risk for ventilator-associated pneumonia (VAP) and other infections. Hand washing is the most effective method of preventing the spread of pathogens that could lead to nosocomial infections. The nurse should perform proper hand hygiene both before and after any patient interaction, as this is critical in preventing the transmission of bacteria or viruses, especially in patients with compromised respiratory systems.

Explanation of each option:

B. Placement of an indwelling urinary catheter using sterile technique:
While using sterile technique when placing an indwelling urinary catheter is essential to prevent urinary tract infections (UTIs), it is not the top priority for infection control in this situation. The primary concern for infection in ARDS patients who are on mechanical ventilation is preventing respiratory infections, particularly ventilator-associated pneumonia (VAP). Although catheter-associated infections should be prevented, the most immediate concern is preventing respiratory-related infections.

C. Initiate neutropenic precautions:
Neutropenic precautions are important for patients who have immunocompromised conditions (such as those undergoing chemotherapy or with bone marrow suppression) to protect them from infections. However, ARDS does not necessarily compromise the immune system in the same way. The priority infection control measure for a patient on a ventilator with ARDS is preventing respiratory infections. Therefore, neutropenic precautions would not be the most relevant or highest priority in this case.

D. Clean technique with central IV line care:
Maintaining clean technique with central intravenous (IV) line care is important to prevent infections, such as central line-associated bloodstream infections (CLABSI). However, the most critical infection control measure for a patient on a ventilator with ARDS is still to focus on preventing respiratory infections, particularly ventilator-associated pneumonia (VAP). While IV line care is important, it is secondary to preventing respiratory tract infections in this scenario.
