A nurse is preparing to administer acyclovir 10 mg/kg IV to a client who weighs 132 lbs. Available is acyclovir IV injectable solution 30 ing/ind Hone many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["20"]

Step 1: Convert Weight to Kilograms

  • 1 lb = 0.4536 kg
  • 132 lb × 0.4536 kg/lb = 59.87 kg

Step 2: Calculate Total Dose of Acyclovir

  • Prescribed dose = 10 mg/kg
  • Total dose = 59.87 kg × 10 mg/kg = 598.75 mg

Step 3: Determine the Volume of Injectable Solution

  • Acyclovir IV concentration = 30 mg/mL
  • Volume = 598.75 mg ÷ 30 mg/mL = 19.96 mL

The nurse should administer 20 mL (rounded to the nearest whole number) of acyclovir IV injectable solution.

Related Questions

Correct Answer is C

Explanation

A. Stroke volume: While stroke volume is an important parameter in assessing cardiac function, it may not directly guide the titration of nitroprusside infusion. Blood pressure is a more immediate indicator of the drug's effect on vasodilation.
B. Urine output: Nitroprusside primarily affects the vascular system and is not directly associated with urine output. Monitoring urine output is crucial in assessing renal function, but it is not the primary parameter for titrating a nitroprusside infusion.
C. Blood pressure (Correct Answer): Nitroprusside acts as a direct vasodilator, and its primary effect is on blood vessels, leading to a reduction in blood pressure. Therefore, monitoring blood pressure is essential to titrate the infusion to achieve the desired therapeutic effect.
D. Cardiac output: While nitroprusside's vasodilatory effect may influence cardiac output indirectly, blood pressure is a more immediate and specific parameter to guide the titration of the infusion. Nitroprusside is often titrated to reach a target blood pressure range in hypertensive emergencies.

Correct Answer is A

Explanation

A. Nitroglycerin: Contraindicated with sildenafil due to the risk of severe hypotension. Both medications cause vasodilation, and their combined use can result in a dangerous drop in blood pressure.
B. Albuterol: Albuterol is not a contraindication for sildenafil. It is a bronchodilator used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD).
C. Furosemide: Furosemide is a diuretic and is not a contraindication for sildenafil. However, it is important to consider the overall health and medical conditions of the individual.
D. Indomethacin: Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) and is not a contraindication for sildenafil. However, individuals taking NSAIDs should be cautious due to potential interactions and side effects.
