Pharm CNS & Anti-bacterial Medications

Acyclovir sodium, also known as Zovirax, is indeed an antiviral medication that is commonly used to treat various types of herpes viruses. It works by inhibiting the replication of the virus, thereby reducing the severity and duration of the infection. This makes the statement "True" as it accurately describes the use of Acyclovir sodium as an antiviral for treating herpes viruses.

Lithium is known to commonly cause a metallic taste as a side effect. This is a common complaint among individuals taking lithium, and it can be an unpleasant and bothersome symptom. It is important for healthcare providers to be aware of this side effect and inform patients who are prescribed lithium about the possibility of experiencing a metallic taste.

Garamycin is effective in treating bacterial infections. It is an antibiotic medication that specifically targets and kills bacteria, making it an appropriate treatment for bacterial infections. It is not effective against fungal, viral, or parasitic infections, as these are caused by different types of organisms.

The nurse should first discuss with the patient their normal bedtime routine and attempt to follow it. This is because insomnia can often be caused by disruptions in a person's regular sleep schedule or routine. By understanding the patient's normal routine and attempting to follow it, the nurse may be able to create a more conducive sleep environment for the patient, potentially alleviating their insomnia. This approach is non-invasive and does not involve medication or external assistance, making it the most appropriate first step in addressing the patient's complaint.

The patient experiencing tongue protrusion, twitching, and eye spasms while taking Sinemet for Parkinson's disease requires immediate attention. These symptoms may indicate a condition called tardive dyskinesia, which is a potential side effect of long-term use of Sinemet. Tardive dyskinesia is characterized by involuntary and repetitive movements of the tongue, lips, face, and other body parts. It is important to address this side effect promptly to prevent further complications and adjust the patient's medication regimen if necessary.

Vancomycin is used to treat resistant staph infections. Staphylococcus aureus, commonly known as staph, can become resistant to many antibiotics, making it difficult to treat. Vancomycin is a powerful antibiotic that is effective against these resistant strains of staph. It works by inhibiting the growth of bacteria and preventing them from forming a cell wall, ultimately killing the bacteria. Vancomycin is often considered a last-resort treatment for staph infections when other antibiotics have failed.

Administering Aspirin to a patient c/o headache would cause a nurse to intervene because Zyloprim is a medication used to treat gout, and aspirin can worsen gout symptoms. Aspirin is known to increase uric acid levels in the body, which can trigger a gout attack. Therefore, it is contraindicated to administer aspirin to a patient receiving Zyloprim. The nurse should intervene to prevent any potential harm or adverse effects to the patient.

When administering a drug with a narrow therapeutic index, obtaining serum peak and trough levels is most important. This is because drugs with a narrow therapeutic index have a small margin of safety, meaning that the difference between a therapeutic dose and a toxic dose is minimal. Monitoring serum peak and trough levels helps to ensure that the drug is within the desired therapeutic range and not reaching toxic levels. By doing so, healthcare professionals can adjust the dosage or frequency of administration as needed to maintain the drug's effectiveness and minimize the risk of toxicity.

Aralen is a medication commonly prescribed for prophylactic use to prevent malaria. Malaria is a parasitic infection that is prevalent in certain regions, known as endemic countries. Therefore, individuals who are traveling to an endemic country are at a higher risk of contracting malaria and would be prescribed Aralen as a preventive measure. The other options, such as having a diagnosis of malaria, coming in contact with an infected person, or experiencing symptoms of parasitic infection, would typically require treatment with antimalarial medications rather than prophylactic use.

Celebrex selectively inhibits COX 2 enzyme, not COX 1. COX 1 and COX 2 are enzymes involved in the production of prostaglandins, which are responsible for inflammation and pain. Celebrex is a nonsteroidal anti-inflammatory drug (NSAID) that specifically targets COX 2 enzymes, reducing inflammation and pain without affecting COX 1 enzymes, which are involved in protecting the stomach lining and promoting platelet aggregation.

The patient who is experiencing nausea/vomiting, diplopia (double vision), and confusion takes priority because these symptoms may indicate a serious adverse reaction to Dilantin. These symptoms could be signs of toxicity or an overdose of the medication. Prompt assessment and intervention are necessary to prevent further complications and ensure the patient's safety.

Zidovudine (AZT) is classified as a nucleoside reverse transcriptase inhibitor. This type of medication works by inhibiting the reverse transcriptase enzyme, which is necessary for the replication of the human immunodeficiency virus (HIV). By inhibiting this enzyme, AZT prevents the virus from multiplying and spreading throughout the body. This class of drugs is commonly used in the treatment of HIV/AIDS to slow down the progression of the disease and improve the immune system function.

It would be appropriate to withhold a dose of AZT when the patient has a WBC count of 3,800/mm3. This is because AZT can cause bone marrow suppression, leading to a decrease in white blood cell count. Therefore, if the patient already has a low WBC count, withholding the dose of AZT can help prevent further suppression and reduce the risk of infection.

Remicade (Infliximad) is used to decrease abdominal cramping and blood in stools in a patient with Crohn's disease. Crohn's disease is an inflammatory bowel disease that causes inflammation in the digestive tract. Remicade is a medication that belongs to a class of drugs called biologics, which work by targeting and blocking a protein called tumor necrosis factor-alpha (TNF-alpha). TNF-alpha plays a key role in causing inflammation in Crohn's disease. By blocking TNF-alpha, Remicade helps reduce inflammation, alleviate symptoms such as abdominal cramping, and decrease the occurrence of blood in stools.

The nurse would withhold the dose of Zidovudine in a patient experiencing N/V (nausea/vomiting) and peripheral neuropathy. N/V can indicate gastrointestinal side effects of the medication, while peripheral neuropathy is a potential adverse effect of Zidovudine. Withholding the dose in this patient would be appropriate to prevent further discomfort or complications.

Dilantin is the correct answer because it is known to cause gingival hyperplasia, which is an overgrowth of the gum tissue. It can also cause decreased coordination and diplopia, which is double vision. Additionally, Dilantin has been associated with Stevens-Johnson syndrome, a severe skin reaction.

The maximum daily dose of Acetaminophen for a healthy adult is 4,000 mg. This is the recommended limit to avoid potential liver damage or other adverse effects. Exceeding this dosage can be harmful and may lead to serious health complications. It is important to follow the recommended guidelines and consult a healthcare professional if necessary.

Acetaminophen (Tylenol) is recommended to be used no longer than 10 days in order to avoid liver damage. Prolonged use of acetaminophen can lead to liver toxicity, as the drug is metabolized by the liver. Therefore, it is important to adhere to the recommended duration of use to prevent any potential harm to the liver.

Mestinon is a medication used to treat myasthenia gravis, a neuromuscular disorder. It works by improving muscle strength and reducing muscle weakness. Contradictions for Mestinon include conditions that may worsen the side effects or interactions with the medication. Diabetes is not a contraindication for Mestinon as it does not have any direct negative effects or interactions with the medication.

The adverse reaction that is NOT listed when taking Isoniazid (INH) is Pancreatitis. Pancreatitis is inflammation of the pancreas and its symptoms include abdominal pain, nausea and vomiting (N/V), high fever, and increased liver enzymes. However, this adverse reaction is not associated with the use of Isoniazid (INH).

A patient experiencing symptoms of hyperglycemia, metabolic acidosis, and vitamin B6 deficiency is likely suffering from side effects of isoniazid. Isoniazid is an antibiotic used to treat tuberculosis, but it can cause these side effects. Hyperglycemia refers to high blood sugar levels, which can occur as a result of isoniazid's effect on glucose metabolism. Metabolic acidosis is an imbalance in the body's pH levels, which can be caused by isoniazid's effect on the body's acid-base balance. Vitamin B6 deficiency can also occur as isoniazid can interfere with the body's ability to absorb and use this vitamin.

The patient complaining of headache, dizziness, and decreased reflexes should take priority because these symptoms may indicate a serious adverse reaction to Aralen, such as neurotoxicity. Neurotoxicity is a potential side effect of Aralen, and it can cause neurological symptoms such as headache, dizziness, and decreased reflexes. It is important to assess and monitor this patient closely to ensure their safety and well-being. The other symptoms reported by the other patients, such as tingling and numbness, urine discoloration, weakness, and fatigue, may also be concerning, but they do not necessarily indicate an immediate life-threatening condition like neurotoxicity.

Redness, swelling, loss of function, heat, and pain are all cardinal signs of inflammation. Redness occurs due to increased blood flow to the area, swelling is caused by fluid accumulation, loss of function refers to impaired movement or use of the affected area, heat is a result of increased blood flow and metabolic activity, and pain is a common symptom of inflammation. These signs indicate the body's response to tissue damage or infection and are essential for diagnosing and treating inflammatory conditions.

A serum salicylate level of 16 mg/dL would indicate a therapeutic range because it falls within the desired range for treating certain conditions. Salicylates, such as aspirin, are commonly used as analgesics and antipyretics. However, they can also be toxic at high levels. A therapeutic range ensures that the medication is effective without causing harm. In this case, a level of 16 mg/dL is within the desired range, suggesting that the medication is being appropriately utilized.

The patient waiting to receive already prepared Ativan via IV takes priority because Ativan is a medication used to treat anxiety and seizures, and the patient may be in need of immediate relief. Administering the medication promptly can help alleviate their symptoms and prevent any potential complications. The other situations mentioned may also require attention, but they do not involve an immediate need for medication administration.

The correct answer choices for the discharge of a patient taking Doxycycline (Vibramycin) are explained as follows:
- Taking the dose with 8 ounces of water, 1 hour before lying down helps prevent ulceration, as Doxycycline can cause irritation to the esophagus.
- Storing the medication out of light and extreme heat ensures its stability and effectiveness.
- Taking the medication around the clock helps to maintain consistent blood levels, which is important for its therapeutic effect.

When checking pupil changes and reaction, pinpoint pupils may indicate Morphine overdose.

Acyclovir (Zovirax) works by decreasing the amount and duration of herpes exacerbations. This means that it helps to reduce the frequency and severity of herpes outbreaks. While it does not cure the infection or prevent transmission, it can significantly improve the quality of life for individuals with herpes by minimizing the frequency and duration of symptoms.

Give at least 6 hours before bedtime, 30-45 minutes before meals

Bananas are high in tyramine, which is a naturally occurring compound found in certain foods. Tyramine can interact with certain medications, such as Sinemet, and may cause an increase in blood pressure. Therefore, it is advised to avoid consuming tyramine-rich foods like bananas while taking Sinemet to prevent any potential adverse effects.

Aralen is classified as an anti-malarial medication. This drug contains chloroquine, which is commonly used to treat and prevent malaria. It works by killing the parasites that cause the disease. Zovirax is an antiviral medication used to treat herpes infections. INH is an antibiotic used to treat tuberculosis. Diflucan is an antifungal medication used to treat various fungal infections.

Aspirin's drug-lab interactions can lead to increased PT and INR levels, indicating potential blood clotting issues. Additionally, it can cause a decrease in potassium levels, which can affect various bodily functions. However, there is no evidence to suggest that aspirin has an effect on uric acid or T3 and T4 levels.

Carisoprodol (Soma) is a muscle relaxant medication commonly used to treat conditions such as stroke, spinal cord injury, multiple sclerosis, and cerebral palsy. It helps to relieve muscle spasms and stiffness associated with these conditions, improving mobility and reducing discomfort. However, Carisoprodol is not indicated for the treatment of Parkinson's disease, rheumatoid arthritis, or myasthenia gravis.

The patient education for a patient taking oral suspension Risperidone (Risperdal) should include teaching them to take their blood pressure and advising them to report any drop of 30 mmHg. This is important because Risperidone can cause hypotension, and monitoring blood pressure can help detect any significant changes. They should also be instructed to store the medication in a light-resistant container and avoid contact with skin during preparation to prevent degradation and potential adverse effects. Additionally, emphasizing the importance of good oral hygiene is necessary to maintain oral health while taking the medication. Lastly, patients should be educated to avoid high heat environments, as Risperidone can increase the risk of hypotension, and heat exposure may exacerbate this effect.

The positive symptoms of schizophrenia are characterized by an excess or distortion of normal functioning. Delusions, paranoia, hallucinations, and incoherent speech are all examples of positive symptoms. These symptoms involve the presence of abnormal thoughts, beliefs, perceptions, and speech patterns. Poor self-care, poverty of speech, and social withdrawal, on the other hand, are considered negative symptoms of schizophrenia, which involve a loss or absence of normal functioning.

The side effects or adverse reactions listed for Nubain include urinary urgency, bitter taste, respiratory depression, and clammy skin. These side effects can occur as a result of taking Nubain.

Haloperidol (Haldol) is an antipsychotic medication that is commonly used to treat schizophrenia, Tourette syndrome, delirium, and hiccups. It is not typically used to treat manic depression or bipolar disorder.

Flagyl is a medication that is used to treat various infections. Renal disease is a contraindication because the drug is primarily eliminated through the kidneys and may accumulate in the body, leading to toxicity. Blood dyscrasias, which refer to disorders of the blood, are also contraindications as Flagyl can potentially worsen these conditions. Contracted visual fields and narrow-angle glaucoma are contraindications because the drug can cause optic neuropathy and worsen glaucoma. PUD, which stands for peptic ulcer disease, is a contraindication because Flagyl can increase the risk of gastrointestinal side effects. Anemia, a condition characterized by a low red blood cell count, is not mentioned as a contraindication for Flagyl.

The contraindications for using Imitrex include a history of myocardial infarction (MI), diabetes, hypertension, smoking, and silent ischemia. These conditions can increase the risk of cardiovascular events and therefore should be considered before prescribing Imitrex. Hypotension and stable angina are not listed as contraindications for using Imitrex.

The side effects of Flagyl include furry tongue, metallic taste, concentrated urine, depression, retinal edema, and peripheral neuropathy. These side effects can occur when taking Flagyl.
