A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously every 12 hr. The client's weight is 121 lb. Available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.6"]
Calculation: 1 mg/kg dose x 121 lb (weight) = 55 kg (approximately) 55 kg x 1 mg = 55 mg (dose required) Enoxaparin 60 mg/0.6 mL = 100 mg/mL Therefore, 55 mg / 100 mg/mL =
0.55 mL (rounded to 0.6 mL).

Correct Answer is B
Explanation
Choice A rationale: Furosemide isn't typically contraindicated with sildenafil use.
Choice B rationale: Nitroglycerin and sildenafil both lower blood pressure, and concurrent use can lead to severe hypotension, making nitroglycerin a contraindication for sildenafil use.
Choice C rationale: Indomethacin isn't generally contraindicated with sildenafil use.
Choice D rationale: Albuterol isn't typically contraindicated with sildenafil use.
Correct Answer is D
Explanation
Choice A rationale: Recurrent headaches might indicate the need for acetaminophen rather than warranting a provider notification.
Choice B rationale: Low blood pressure (BP 92/60 mm Hg) is not a contraindication for acetaminophen use.
Choice C rationale: Hypothyroidism might not directly impact the administration of acetaminophen.
Choice D rationale: Acetaminophen is metabolized by the liver and can cause hepatotoxicity in high doses or in clients who have liver impairment. A history of alcohol use disorder can indicate chronic liver damage and increase the risk of adverse effects from acetaminophen. Therefore, the nurse should notify the provider before administering the medication to this client.
