A nurse is caring for a client who is scheduled for a bone marrow aspiration. The client asks the nurse about the sites the provider might use for the procedure. Which of the following locations should the nurse identify as one of the sites used for this procedure?

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.

A. "Only take one nitroglycerin tablet for each episode of angina."

This instruction is correct. Sublingual nitroglycerin is typically administered as needed for the relief of angina symptoms, with one tablet being the initial dose. If the chest pain persists after 5 minutes, the client may take a second tablet, and if needed, a third tablet after another 5 minutes. However, if the pain is not relieved after three tablets, they should seek immediate medical attention.

B. "Place the nitroglycerin tablet between cheek and gum."

This instruction is incorrect. Sublingual nitroglycerin tablets should be placed under the tongue, allowing them to dissolve and be absorbed directly into the bloodstream. Placing the tablet between the cheek and gum is not the recommended administration route for sublingual nitroglycerin.

C. "Call 911 if you develop a headache following nitroglycerin use."

This instruction is partially correct. Headache is a common side effect of nitroglycerin due to its vasodilatory effects. Clients should be informed about this potential side effect, but not every headache following nitroglycerin use requires immediate medical attention. However, if the headache is severe, persistent, or accompanied by other concerning symptoms, the client should seek medical evaluation.

D. "See if rest relieves the chest pain before using the nitroglycerin."

This instruction is incorrect. Sublingual nitroglycerin is a rapid-acting medication used to relieve angina symptoms quickly. Clients should not delay taking nitroglycerin and wait for rest to relieve chest pain, as this can lead to worsening symptoms and complications.
