What action would be most helpful to the nurse in determining whether the chest pain of a patient who has just entered the emergency department is cardiac in origin?

A.

Performing a 12-lead ECG

B.

Administering NTG to see if the pain goes away

C.

Gathering a complete medical history

D.

Asking the patient if performing a Valsalva maneuver reduces the pain

Answer and Explanation

The Correct Answer is A

A. Performing a 12-lead ECG: An ECG is the most definitive and immediate tool to determine if chest pain is cardiac in origin, as it can detect ischemic changes, arrhythmias, or other cardiac abnormalities.

B. Administering NTG to see if the pain goes away: While nitroglycerin (NTG) may relieve ischemic chest pain, it is not definitive for diagnosing the pain's origin and should not be the first step without further assessment.

C. Gathering a complete medical history: Although a medical history is important, it will not immediately determine if the pain is cardiac in origin.

D. Asking the patient if performing a Valsalva maneuver reduces the pain: The Valsalva maneuver is not a reliable method to differentiate cardiac from non-cardiac chest pain and could potentially worsen certain conditions.

Correct Answer is B

Explanation

A. Patient stopped smoking five years prior to hospitalization: Smoking cessation materials are typically targeted to current smokers or those who have quit very recently (usually within the last year). This patient may not need smoking cessation materials as they have been smoke-free for a significant period.

B. Patient smokes five cigars a week: Smoking cigars still carries health risks similar to cigarettes and indicates the need for smoking cessation materials.

C. Patient uses chewing tobacco: Chewing tobacco is a form of smokeless tobacco, and while harmful, it would require different educational materials focused on smokeless tobacco cessation rather than smoking cessation.

D. Patient smoked cigarettes any time during the last year prior to hospitalization: This indicates current or recent smoking behavior which is a significant risk factor that needs to be addressed.

Correct Answer is ["50"]

Explanation

Available: Octreotide 0.5 mg in 100 mL of fluid

Calculation:

Convert the available dose to mcg:

  • 0.5 mg = 500 mcg

Determine the concentration:

  • 500 mcg in 100 mL = 5 mcg/mL

Calculate the infusion rate:

  • Desired rate: 50 mcg/hour
  • Infusion rate (mL/hour) = Desireddose(mcg/hour)÷ Concentration(mcg/mL)

= 50 mcg/hour ÷ 5 mcg/Ml

= 10 mL/hour

The infusion rate of 10 mL/hour will deliver 50 mcg/hour of Octreotide, as prescribed.
