Low molecular weight heparin (LMWH) is used for what type of patient?
Patients with. hypertension
Patients with asthma
Patients with diabetes
Patients with deep vein thrombosis (DVT)
The Correct Answer is D
A) Patients with hypertension
Low molecular weight heparin (LMWH) is not primarily used to treat hypertension. Hypertension (high blood pressure) is typically managed with antihypertensive medications like ACE inhibitors, beta-blockers, diuretics, or calcium channel blockers. LMWH is an anticoagulant, which works to prevent blood clots rather than controlling blood pressure.
B) Patients with asthma
LMWH is not typically used to treat asthma. Asthma is a chronic respiratory condition that is usually managed with bronchodilators (e.g., albuterol) and anti-inflammatory drugs such as corticosteroids. While patients with asthma may be at risk for blood clots under certain conditions (e.g., severe asthma exacerbations, immobility), LMWH is not a first-line treatment for asthma.
C) Patients with diabetes
While people with diabetes may be at an increased risk of developing blood clots, LMWH is not specifically used to treat diabetes. Diabetes is typically managed with insulin, oral hypoglycemic agents, lifestyle modifications, and other medications to control blood glucose levels. LMWH is an anticoagulant used for conditions that require prevention of clot formation, such as deep vein thrombosis (DVT).
D) Patients with deep vein thrombosis (DVT)
LMWH is commonly prescribed to patients with deep vein thrombosis (DVT). DVT occurs when a blood clot forms in a deep vein, usually in the legs. LMWH is a type of anticoagulant that prevents the formation of further clots by inhibiting factors involved in blood clotting. It is especially effective for patients with DVT or those at high risk for thromboembolic events, such as after surgery or during prolonged immobility. LMWH provides more predictable anticoagulation and requires less frequent monitoring than unfractionated heparin, making it ideal for outpatient management and in hospital settings.

Correct Answer is C
Explanation
Let's calculate the dosage using the provided information.
Information from the label:
Bumetanide concentration: 0.25 mg/mL
Available volume: 10 mL vial
Order: Bumex (bumetanide) 1 mg IV daily
Calculation:
Determine the desired dose: 1 mg
Use the formula:
Desired dose (mg) / Available concentration (mg/mL) = Volume to administer (mL)
Substitute the values:
1 mg / 0.25 mg/mL = Volume to administer (mL)
Calculate:
Volume to administer = 4 mL
Therefore, the correct answer is C. 4 mL
Correct Answer is D
Explanation
A) Antibiotics
Antibiotics are medications used to treat infections by killing or inhibiting the growth of bacteria. They do not have any direct effect on clot formation. Antibiotics work by targeting specific parts of bacterial cells, such as cell walls, proteins, or DNA, but they do not interfere with the blood coagulation system. Therefore, antibiotics are not a drug group that inhibits clot formation.
B) Analgesics
Analgesics are pain-relieving medications used to reduce pain, and they include both non-opioid (e.g., acetaminophen, NSAIDs) and opioid medications (e.g., morphine, oxycodone). While some analgesics, particularly nonsteroidal anti-inflammatory drugs (NSAIDs), can affect platelet function and may slightly influence clotting, their primary function is to relieve pain.
C) Antidepressants
Antidepressants are medications used to treat mood disorders, including depression, anxiety, and other psychiatric conditions. These drugs work by altering the balance of neurotransmitters in the brain, such as serotonin, norepinephrine, or dopamine. Antidepressants do not directly affect blood clotting mechanisms, although some classes, such as selective serotonin reuptake inhibitors (SSRIs), can have mild anticoagulant effects due to their impact on platelet aggregation.
D) Anticoagulants
Anticoagulants inhibit the coagulation cascade, a series of complex biochemical reactions that lead to the formation of a blood clot. Common examples of anticoagulants include warfarin, heparin, and the newer direct oral anticoagulants (DOACs) such as rivaroxaban and apixaban. Anticoagulants are primarily used to reduce the risk of clot formation in conditions such as deep vein thrombosis (DVT), pulmonary embolism (PE), and atrial fibrillation (AF), and they are essential in managing and preventing clot-related complications.
