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 B
Explanation
B. The correct angle for insulin injections is typically 90 degrees when administering into areas with adequate subcutaneous tissue, such as the abdomen or thigh.
A. Insulin injections should not be administered rapidly, as this can cause discomfort or bruising at the injection site. Additionally, a 20-gauge needle is too large for insulin injections, which typically require smaller gauge needles.
C. Insulin injections are typically administered using insulin syringes, not tuberculin syringes. Additionally, the recommended angle for insulin injections is 90 degrees, not 15 degrees.
D. The Z-track method is a technique used to minimize medication leakage or staining of the skin when administering certain medications, particularly those with irritating properties or medications given intramuscularly.
Correct Answer is B
Explanation
B. Headache, particularly a pounding headache or throbbing sensation, is a well-known side effect of nitroglycerin use. It occurs due to the vasodilatory effects of nitroglycerin, which can lead to dilation of blood vessels in the head and neck.
A. Ringing in the ears, also known as tinnitus, is not a common adverse effect of nitroglycerin. Tinnitus is typically associated with certain medications, exposure to loud noises, or underlying medical conditions such as inner ear disorders. It is not a recognized adverse effect of nitroglycerin.
C. Nitroglycerin is not known to increase blood pressure. In fact, it typically causes vasodilation and can lead to a decrease in blood pressure, especially when used sublingually or transdermally. Hypotension, rather than hypertension, is a potential adverse effect of nitroglycerin therapy.
D. Polyuria, or excessive urination, is not a recognized adverse effect of nitroglycerin. Polyuria may occur as a result of other medications or underlying medical conditions affecting renal function, but it is not directly associated with nitroglycerin use.
