Which of the following is stated correctly using metric abbreviations and rules?

A.

Ampicillin 500 mg

B.

ampicillin mg 500

C.

ampicillin 500 MG

D.

ampicillin 500.0 mg

Answer and Explanation

The Correct Answer is A

A) Ampicillin 500 mg
This is correctly written using metric abbreviations and follows standard rules for medication dosage. In the metric system, the drug name is followed by the dose, with the unit of measurement ("mg" for milligrams) written in lowercase. The correct usage of the unit abbreviation "mg" and proper spacing between the medication and the dose makes this option correct. Additionally, no trailing zeros are used, which is important for avoiding confusion in clinical settings.

 

B) ampicillin mg 500
This is incorrect because the unit of measurement ("mg") should follow the dose, not precede it. The correct format places the drug name first, followed by the numerical dose, and then the unit of measurement (in this case, "mg"). The unit abbreviation should be lowercase and placed after the dose. This structure is standard in pharmaceutical and medical documentation.

 

C) ampicillin 500 MG
While this provides the correct drug name and dosage, the unit abbreviation "MG" is written in uppercase, which is incorrect according to standard guidelines. Unit abbreviations should be written in lowercase letters unless they are the first word in a sentence. Writing "MG" in uppercase can lead to confusion and does not follow the convention for unit symbols.

 

D) ampicillin 500.0 mg
This is also incorrect because of the unnecessary trailing zero after the decimal point. In medication dosage, a trailing zero (e.g., 500.0 mg) is considered a potential error, as it can be misinterpreted. For example, a dosage of "500.0 mg" may be misread as a higher dose (e.g., 500 mg vs. 500.0 mg), and this could lead to medication errors. Standard practice is to avoid using trailing zeros unless they are required to prevent ambiguity (e.g., 0.5 mg).

Correct Answer is D

Explanation

Given:

Ordered dose of Lithium: 300 mg

Available Lithium capsules: 150 mg/capsule

Step 1: Calculate the number of capsules required:

Number of capsules = Desired dose (mg) / Strength of each capsule (mg/capsule)

Number of capsules = 300 mg / 150 mg/capsule

Number of capsules = 2 capsules

Correct Answer is D

Explanation

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.
