Your answer: 2 An inpatient takes lovastatin 40 mg every 24 hours, and you need to use 20 mg tablets. To achieve the 40 mg dosage, you should put 2 of the 20 mg tablets in the med cart drawer.
Lovastatin is a medication used to lower cholesterol levels in the blood. It belongs to a class of medications called statins, which work by inhibiting an enzyme called HMG-CoA reductase, which plays a key role in the production of cholesterol in the liver. By blocking this enzyme, statins reduce the amount of cholesterol produced by the liver, which in turn lowers the overall cholesterol levels in the blood.The usual dose of lovastatin for adults is 20-80 mg per day, taken once daily with the evening meal. The starting dose is usually 20 mg, and the dose may be increased as needed to achieve the desired cholesterol-lowering effect. It is important to take lovastatin regularly and as directed by the healthcare provider, and to not exceed the prescribed dose.

The conduction system contains pacemaker cells, nodes, the ____ and the ____.
A) Purkinje fibers and bundle of His
B) Heart valves and purkinje fibers
C) Electrical system and bundle of His
D) Bundle of His and electrical system
The correct answer is A) Purkinje fibers and bundle of His.The conduction system of the heart is responsible for the coordinated contraction of its muscle fibers, which is essential for its proper function. The system comprises a network of specialized cardiac muscle cells that conduct electrical impulses throughout the heart, initiating each heartbeat and regulating its rhythm.
At the core of the conduction system are the pacemaker cells, which generate electrical impulses spontaneously and act as the primary source of cardiac rhythm. These cells are located in the sinoatrial (SA) node, which is located in the upper right atrium of the heart.From the SA node, the electrical impulses travel through specialized pathways of cells, including the atrioventricular (AV) node and the bundle of His. The AV node serves as a gatekeeper that slows down the impulses before allowing them to pass into the ventricles. The bundle of His then divides into right and left bundle branches, which deliver the impulses to the Purkinje fibers, the final conducting cells that spread the electrical signal throughout the ventricles, causing them to contract. In summary, the conduction system contains pacemaker cells, nodes (SA and AV), the bundle of His, and the Purkinje fibers, all of which work together to regulate and coordinate the electrical activity of the heart.

A nurse is caring for a newborn that is large for gestational age (LGA). What is an expected finding of a macrosomic infant?
A. Decreased subcutaneous fat
B. Dry, loose skin
C. Sluggishness, hypotonic muscles
D. Bronze skin discoloration
A macrosomic infant is one that is larger than average, typically weighing more than 8 pounds and 13 ounces at birth. While there may be some variation in size and weight, an LGA baby is usually born weighing over 9 pounds and 15 ounces.
When caring for a newborn that is large for gestational age, one of the expected findings is decreased subcutaneous fat. This is because the infant has had more time in the uterus to accumulate fat stores, making them larger in size.
However, dry, loose skin and sluggishness or hypotonic muscles are not expected findings of a macrosomic infant. Rather, these could indicate other underlying medical conditions or complications that should be further assessed by a healthcare provider. Bronze skin discoloration is also not typically associated with being macrosomic.It is important for healthcare providers to closely monitor and assess LGA infants, as they are at a higher risk for complications such as shoulder dystocia during delivery, neonatal hypoglycemia, and respiratory distress syndrome. Close observation and care can help ensure that these infants receive appropriate interventions and treatments as needed.

Which waveform is most likely to determine the beneficial effects of a bronchodilator treatment
The most likely waveform to determine the beneficial effects of a bronchodilator treatment is a flow-volume loop, which measures airflow during inspiration and expiration.
A flow-volume loop is a graphical representation of airflow during inspiration and expiration. It is commonly used to evaluate lung function and diagnose respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). In patients with these conditions, airflow is often obstructed, resulting in decreased lung function and symptoms such as shortness of breath and wheezing. Bronchodilator medications work by relaxing the smooth muscles of the airways, allowing for increased airflow and improved lung function.
By measuring the changes in airflow before and after a bronchodilator treatment, a flow-volume loop can help determine the effectiveness of the treatment and the extent of the patient's airway obstruction. Therefore, a flow-volume loop is the most likely waveform to determine the beneficial effects of a bronchodilator treatment.

1 part of 5%, 3 parts of 1%
1 part of 2%, 4 parts of 1%
5 parts of 1%, 2 parts of 3%
To prepare a lidocaine 2% cream using a lidocaine 1% cream and a lidocaine 5% cream, you need to use the concept of mixing ratios.
A 2% lidocaine cream contains 2 parts of lidocaine per 100 parts of cream, while a 5% lidocaine cream contains 5 parts of lidocaine per 100 parts of cream. To make a 2% cream from these two creams, we need to find the right proportion of each.
Let x be the number of parts of the 1% cream we need, and y be the number of parts of the 5% cream we need. Then we can set up the following equation:
2 = (x + y) / (x + y + 100)
This equation says that the total amount of lidocaine in the final cream should be 2% (or 2 parts per 100 parts of cream). We can simplify this equation by multiplying both sides by (x + y + 100):
2(x + y + 100) = x + y
Expanding the left side and simplifying, we get:
x = 3y
This equation tells us that for every part of the 5% cream we use, we need three parts of the 1% cream. Therefore, the correct answer is 1 part of 5% and 3 parts of 1%.

Which medication does the nurse plan to administer to a client before chemotherapy to decrease the incidence of nausea and vomiting?
A. Morphine
B. Ondansetron (Zofran)
C. Naloxone (Narcan)
D. Diazepam (Valium)
The nurse plans to administer Ondansetron (Zofran) to a client before chemotherapy to decrease the incidence of nausea and vomiting.
Ondansetron is a medication that belongs to a class of drugs called serotonin receptor antagonists. It works by blocking the action of serotonin, a chemical in the body that can trigger nausea and vomiting. The medication is typically given before chemotherapy to prevent these side effects from occurring.
Chemotherapy is a treatment that can be very effective in killing cancer cells, but it can also cause a range of unpleasant side effects, including nausea and vomiting. These side effects can be debilitating and can interfere with a patient's ability to continue with their treatment. The administration of Ondansetron before chemotherapy can help to alleviate these side effects, allowing the patient to continue with their treatment and ultimately improving their chances of a successful outcome.
