A nurse is caring for a client who is receiving heparin 3,800 units subcutaneously daily. Available is heparin 5,000 units/mL. How many mL should the nurse administer? Round to thenearesttenth

Answer and Explanation

The Correct Answer is ["0.8"]

To calculate the volume of heparin to administer subcutaneously, you can use the following formula:

Volume (mL) = Desired dose (units) / Concentration (units/mL)

In this case:

Desired dose = 3,800 units

Concentration = 5,000 units/mL

Volume (mL) = 3,800 units / 5,000 units/mL ≈ 0.76 mL

Rounded to the nearest tenth, the nurse should administer approximately 0.8 mL of heparin subcutaneously daily.

Correct Answer is C

Explanation

A. Initiate cardiopulmonary resuscitation (CPR): CPR is not indicated in this scenario unless the client experiences a cardiac arrest. Chest pain during an exercise stress test does not automatically warrant CPR.

B. Administer sublingual nitroglycerin to allow the client to finish the test: Nitroglycerin is typically used to relieve angina (chest pain) associated with myocardial ischemia. However, in this case, the exercise stress test should be stopped to evaluate the cause of the chest pain before administering nitroglycerin.

C. Stop the test and monitor the client closely: This is the correct action. Chest pain during an exercise stress test may indicate myocardial ischemia (lack of blood flow to the heart muscle), and stopping the test allows for further assessment and evaluation of the client's condition.

D. Administer analgesia and slow the test: Administering analgesia (pain medication) is not appropriate without first determining the cause of the chest pain. Slowing the test may not address the underlying issue and could potentially worsen the client's condition if they are experiencing cardiac-related chest pain.

A. The blood was infused too quickly and overwhelmed the client's circulatory system. B. The donor blood was incompatible with that of the client. C. The client had a sensitivity reaction to a plasma protein in the blood. D. Antibodies to donor leukocytes remained in the blood.

Correct Answer is B

Explanation

A. The blood was infused too quickly and overwhelmed the client's circulatory system:

While infusing blood too quickly can lead to circulatory overload and related complications like heart failure or pulmonary edema, it is not the cause of an acute hemolytic transfusion reaction. Acute hemolytic reactions occur due to immune responses against incompatible donor blood.

B. The donor blood was incompatible with that of the client:

This is the correct answer. An acute hemolytic transfusion reaction happens when there is an incompatibility between the donor's blood and the recipient's blood. This can occur due to mismatched ABO blood types or Rh factor, leading to the recipient's immune system attacking and destroying the transfused red blood cells.

C. The client had a sensitivity reaction to a plasma protein in the blood:

Sensitivity reactions to plasma proteins can occur, but they typically result in different types of transfusion reactions, such as allergic reactions or febrile non-hemolytic reactions. These reactions are caused by antibodies to specific plasma proteins and are not the cause of acute hemolytic transfusion reactions.

D. Antibodies to donor leukocytes remained in the blood:

This option refers to febrile non-hemolytic transfusion reactions, which occur due to antibodies against donor leukocytes. However, this type of reaction is distinct from acute hemolytic reactions, which are primarily caused by ABO or Rh incompatibility.
