Nursing Elites

1. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

2. A client is receiving brachytherapy for treatment of prostate cancer. Which of the following actions should the nurse take?

• A. Cleanse equipment before removal from the client's room.
• B. Limit the client's visitors to 30 minutes per day.
• C. Discard the client's linens in a double bag.
• D. Discard the radioactive source in a biohazard bag

Correct answer: D

Rationale: When caring for a client receiving brachytherapy, it is crucial to handle radioactive sources appropriately. Discarding the radioactive source in a biohazard bag is essential to prevent exposure to radiation. Cleaning equipment before removal, limiting client's visitors, or discarding linens in a double bag are not specific to the management of radioactive sources in brachytherapy.

3. What is the initial technique used when examining a client's abdomen?

• A. Palpation
• B. Auscultation
• C. Percussion
• D. Inspection

Correct answer: D

Rationale: When examining a client's abdomen, the initial technique used is inspection. Inspection involves visually assessing the abdomen for any abnormalities, such as distention, scars, or rashes. This step allows the healthcare provider to gather valuable information before proceeding to other examination techniques like palpation, auscultation, and percussion. Palpation, auscultation, and percussion are secondary techniques used after visual inspection to further assess the abdomen for specific findings. Palpation involves feeling the abdomen for masses or tenderness, auscultation is listening for bowel sounds, and percussion is tapping the abdomen to assess for areas of dullness or resonance.

4. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.

5. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.
