1. A healthcare provider is preparing to administer a transfusion of a unit of packed red blood cells (PRBCs) for a client who has severe anemia. Which of the following interventions will prevent an acute hemolytic reaction?

A. Ensure that the client has a patent IV line before obtaining the blood product from the refrigerator.
B. Obtain help from another healthcare provider to confirm the correct client and blood product.
C. Take a complete set of vital signs before beginning the transfusion and periodically during the transfusion.
D. Stay with the client for the first 15 to 30 minutes of the transfusion.

Correct answer: B

Rationale: The correct answer is to obtain help from another healthcare provider to confirm the correct client and blood product. This action is crucial in preventing an acute hemolytic reaction, which is caused by ABO or Rh incompatibility. Verifying the correct client and blood product before the transfusion ensures that there are no errors in identification, reducing the risk of a potentially life-threatening reaction. Choices A, C, and D are important aspects of transfusion safety but are not directly related to preventing acute hemolytic reactions. Ensuring a patent IV line, monitoring vital signs, and staying with the client are all essential during transfusion but do not specifically address the risk of ABO or Rh incompatibility reactions.

2. A client has a new prescription for Methotrexate. Which of the following instructions should be included in the teaching?

A. Avoid drinking alcohol while taking this medication.
B. Take the medication with a high-fat meal.
C. Expect increased hair growth.
D. You should never stop taking the medication without consulting your healthcare provider.

Correct answer: A

Rationale: The correct instruction for a client taking Methotrexate is to avoid drinking alcohol. Methotrexate can cause liver toxicity, and alcohol consumption can increase this risk. It is important to emphasize the avoidance of alcohol while on this medication to prevent adverse effects and ensure treatment effectiveness. The other options are incorrect: Taking Methotrexate with a high-fat meal is not necessary as it can be taken with or without food. Increased hair growth is not an expected effect of Methotrexate; in fact, hair loss is a potential side effect. Stopping the medication without consulting a healthcare provider can be dangerous and may lead to worsening of symptoms or relapse, making option D incorrect.

3. Which of the following is a potassium-sparing diuretic?

A. Furosemide
B. Spironolactone
C. Hydrochlorothiazide
D. Bumetanide

Correct answer: B

Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.

4. Which of the following is not a known effect of the drug Clozapine?

A. Agranulocytosis
B. Antipsychotic
C. Used for Schizophrenia
D. Hyperactivity

Correct answer: D

Rationale: Clozapine is associated with side effects like agranulocytosis (a serious blood condition), sedation (not hyperactivity), and is used as an antipsychotic to treat schizophrenia. Hyperactivity is not a typical effect of Clozapine, making it the correct answer in this context.

5. A hospitalized client has an activated partial thromboplastin time (aPTT) greater than 1.5 times the expected reference range. Which of the following blood products should be prepared for transfusion?

A. Whole blood
B. Platelets
C. Fresh frozen plasma
D. Packed red blood cells

Correct answer: C

Rationale: Fresh frozen plasma is the appropriate blood product for a client with an elevated aPTT as it contains various coagulation factors that can help correct coagulopathies and prevent bleeding. Elevated aPTT indicates a deficiency in specific clotting factors, and fresh frozen plasma is rich in these factors. Whole blood, platelets, and packed red blood cells do not contain the necessary coagulation factors to correct an elevated aPTT, so they are not indicated in this situation.
