A nurse is preparing to administer enoxaparin 5 mg/kg subcutaneous daily to a client who has deep-vein thrombosis. The client weighs 152 lb. Available is 120 mg/0.8 mL prefilled syringe. Calculate the dosage in mL that the nurse should administer. (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
The Correct Answer is ["2.3"]
1 lb = 0.453592 kg (conversion factor)
Weight in kilograms = 152 lb × 0.453592 kg/lb ≈ 68.946 kg
Calculate the total dosage based on the client's weight:
Total dosage = 5 mg/kg × 68.946 kg
≈ 344.73mg
Determine the volume of enoxaparin solution needed based on the concentration provided: Available concentration: 120 mg/0.8 mL
Dosage required: 344.73 mg Using the formula:
Volume (mL) = Dosage required (mg) / Concentration (mg/mL)
= 344.73mg / 120 mg/0.8 mL
= 2.3ml

Correct Answer is A
Explanation
A. Sore throat is a common side effect of carbamazepine. Carbamazepine causes agranulocytosis whose earliest sign is a sore throat.
B. Gingivitis is not a side effect associated with carbamazepine.
C. Urge incontinence, or the sudden, uncontrollable urge to urinate, is not a common adverse effect of carbamazepine.
D. Increased salivation is not a typical adverse effect of carbamazepine. While dry mouth is a possible side effect, increased salivation would be unusual.
Correct Answer is C
Explanation
C. Sublingual nitroglycerin is rapidly absorbed through the mucous membranes under the tongue, and its effects are usually felt within 1 to 5 minutes. Patients should experience relief from angina symptoms shortly after administration.
A. While sublingual nitroglycerin can be taken every 5 minutes for a maximum of three doses for acute angina attacks, it should not be taken every 10 minutes. Taking it too frequently can lead to excessive vasodilation and potentially harmful side effects.
B. Nitroglycerin primarily dilates blood vessels rather than affecting heart rate. While it may cause a transient decrease in blood pressure, it does not typically slow heart rate.
D. Sublingual nitroglycerin should be taken on an empty stomach for optimal absorption. Food can delay absorption and decrease the effectiveness of the medication.
