The nurse is caring for a client diagnosed with amyotrophic lateral sclerosis (ALS). The client was given a medical prescription for tizanidine. What information would the nurse provide regarding this medication? Tizanidine is
a sleep aid and used to promote sleep along with melatonin.
a muscle relaxant medication used to reduce muscle spasms.
an antibiotic medication used to treat bacterial infections.
an opiate and is used to relieve severe pain.
The Correct Answer is B
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.

Correct Answer is D
Explanation
A. Resume smoking initially to help manage stress and anxiety:
Smoking is a significant risk factor for cardiovascular disease and can worsen the prognosis after coronary artery bypass graft (CABG) surgery. Smoking increases the risk of coronary artery disease and impairs healing after surgery. Therefore, advising the client to resume smoking, even temporarily, is unsafe and completely contrary to health recommendations for post-CABG care. Smoking cessation should be emphasized as a key part of the recovery process.
B. Consume a high-fat diet to promote weight gain and energy:
A high-fat diet is not recommended for individuals with coronary artery disease, especially after CABG surgery. Consuming a diet high in saturated fats and cholesterol can lead to further plaque buildup in the coronary arteries, increasing the risk of atherosclerosis and cardiac events. After CABG, patients are typically encouraged to follow a heart-healthy diet that is low in saturated fat, high in fiber, and rich in fruits, vegetables, and lean proteins to support overall heart health and recovery.
C. Avoid physical activity and rest as much as possible:
While rest is essential immediately following surgery, complete avoidance of physical activity is not advisable long-term. In fact, early and gradual physical activity is a key component of rehabilitation after CABG surgery. A sedentary lifestyle can increase the risk of complications such as blood clots, muscle weakness, and weight gain, while physical activity helps improve circulation, heart function, and overall recovery. The nurse should encourage the client to gradually resume physical activity according to the guidance of their healthcare provider, often starting with light walking and progressing as tolerated.
D. Continue taking all prescribed medications as directed: Following coronary artery bypass graft (CABG) surgery, it is essential for the client to continue taking all prescribed medications, including antiplatelets, statins, beta-blockers, and any other medications ordered by the healthcare provider. These medications play a critical role in preventing blood clots, controlling blood pressure, reducing cholesterol levels, and preventing future cardiac events. Stopping or altering medications without consulting a healthcare provider could increase the risk of complications or recurrent cardiac events.
Correct Answer is B
Explanation
Explanation of each option:
A. Respiratory rate of 10 breaths per minute:
A respiratory rate of 10 breaths per minute would be too slow in a patient with ARDS and hypoxemia. In response to hypoxemia, the body typically increases the respiratory rate to improve oxygenation. A respiratory rate of 10 breaths per minute would not be expected in this situation.
B. Respiratory rate of 32 breaths per minute: The arterial blood gas (ABG) results indicate respiratory alkalosis with hypoxemia, which is a common finding in patients with acute respiratory distress syndrome (ARDS). pH 7.59: This is alkalotic, meaning the body is experiencing respiratory alkalosis.
PaCO2 29 mmHg: The PaCO2 is low, indicating hyperventilation, which is a compensatory response to the alkalosis in an attempt to reduce carbon dioxide levels.
PaO2 55 mmHg: This is severely low, indicating hypoxemia (low oxygen levels in the blood), a hallmark of ARDS. HCO3 22 mEq/L: The bicarbonate is normal, suggesting that the metabolic component has not yet compensated for the respiratory alkalosis, or that it is in the early stages of compensation. Given these ABG results, the body is attempting to compensate for hypoxemia by increasing respiratory rate (tachypnea), which leads to hyperventilation and further reduction in PaCO2. Therefore, an expected assessment finding in this scenario would be a high respiratory rate (such as 32 breaths per minute), which is a compensatory response to hypoxemia.
C. Blood pressure 86/42 mmHg:
While hypotension can occur in severe cases of ARDS due to impaired oxygenation and circulation, it is not directly reflected by the ABG results provided. Hypoxemia and alkalosis would more likely lead to tachypnea and compensatory mechanisms like tachycardia, rather than significant hypotension unless there is another contributing factor, such as shock or sepsis. Therefore, hypotension is not the most expected finding based on these ABGs.
D. Heart rate of 45 beats per minute:
A heart rate of 45 beats per minute is bradycardic, which would be unusual in a patient with hypoxemia and respiratory alkalosis. Tachycardia is a more common compensatory response to hypoxia, as the heart works harder to improve oxygen delivery to tissues. A heart rate of 45 beats per minute would be more suggestive of a different underlying condition, such as vagal stimulation or cardiac conduction issues, but it is not the expected response in this case.
