What is the primary advantage of using low molecular weight heparins (LMWHs) over heparin?
LMWHs produce a more stable effect on coagulation; thus, fewer lab tests are needed.
LMWHs may be given by the oral route
LMWHs have a short duration of action
LMWHs possess greater anticoagulant activity
The Correct Answer is A
A. LMWHs produce a more stable effect on coagulation; thus, fewer lab tests are needed: Correct LMWHs have a more predictable anticoagulant response compared to unfractionated heparin, resulting in a more stable effect on coagulation. Because of their predictable response, routine monitoring of coagulation parameters, such as activated partial thromboplastin time (aPTT), is typically not required with LMWH therapy, unlike with unfractionated heparin.
B. LMWHs may be given by the oral route: Incorrect. LMWHs are administered by the subcutaneous route.
C. LMWHs have a short duration of action: Incorrect. LMWHs have a longer duration of action compared to unfractionated heparin.
D. LMWHs possess greater anticoagulant activity: incorrect. LMWHs generally have less potent anticoagulant activity compared to unfractionated heparin, but their more predictable response and longer half-life make them advantageous in many clinical scenario

Explanation
To find the volume of amoxicillin solution the nurse needs to administer, we can divide the desired dose (300 mg) by the concentration of the solution (250 mg/5 mL).
Here's the calculation:
Amoxicillin volume (mL) = Desired dose (mg) / Concentration (mg/mL) Amoxicillin volume (mL) = 300 mg / 250 mg/5 mL
Since we're dividing by a fraction, it's mathematically equivalent to multiply by the reciprocal of the fraction. The reciprocal of 250 mg/5 mL is 5 mL/250 mg.
Amoxicillin volume (mL) = 300 mg * (5 mL / 250 mg)
Cancel out the milligrams (mg) units:
Amoxicillin volume (mL) = 300 mg / 250 mg * 5 mL
Amoxicillin volume (mL) = 1.2 mL (rounded to one decimal place)
However, since we are dealing with medication, it's best to round to the nearest whole number for accuracy in administering the dose.
Therefore, the nurse should administer 6.0 mL of amoxicillin oral solution.
Correct Answer is B
Explanation
A. Have suction equipment at the bedside. Clopidogrel is an antiplatelet medication that inhibits blood clot formation. While it does not typically increase the risk of bleeding to the extent that requires constant suctioning, it's prudent to have suction equipment readily available for any patient who may be at risk of bleeding due to their underlying condition or concurrent medications. However, the administration of clopidogrel alone does not necessitate the need for constant suctioning.
B. Monitor the client for black, tarry stools. This is the correct answer. Clopidogrel, like other antiplatelet medications, increases the risk of bleeding, including gastrointestinal bleeding. Black, tarry stools can indicate gastrointestinal bleeding, which can be a serious complication of clopidogrel therapy. Therefore, monitoring for this symptom is essential for early detection of potential bleeding complications.
C. Administer the medication with each meal. Clopidogrel can be administered with or without food, as it is not significantly affected by food intake. However, there is no specific recommendation to administer it with meals. The timing of administration may vary based on the prescriber's instructions or patient preferences, but it does not need to be consistently administered with meals.
D. Initiate contact precautions. Clopidogrel therapy does not require contact precautions. Contact precautions are typically implemented for patients with contagious infections that spread via direct or indirect contact. Clopidogrel does not pose a risk of transmission to others and does not warrant contact precautions.
