Dr. Smith orders a gram of human salt poor albumin product for a patient. The product is available in a 50-milliliter vial with a concentration of 25 percent. What dosage will the nurse administer?

Correct Answer: D

Rationale: A 25 percent albumin solution contains 25 grams of albumin per 100 milliliters. To administer 1 gram of albumin, the nurse would calculate the volume as follows: 1 gram ÷ 25 grams/100 milliliters = 4 milliliters. Therefore, the nurse will administer 4 milliliters of the 25 percent albumin solution to deliver the ordered dose of 1 gram. Using the entire vial or not using the product at all would be incorrect.

Correct Answer: B

Rationale: Before administering Digoxin, it is crucial for the nurse to count the patient's apical pulse for 1 minute. Digoxin is a medication commonly prescribed to manage heart conditions such as heart failure and certain irregular heartbeats. Since Digoxin works by helping the heart beat stronger and at a more normal rhythm, it is essential to monitor the patient's heart rate before administering the medication. Counting the apical pulse for 1 minute allows for an accurate assessment of the patient's baseline heart rate, which is crucial in determining whether it is safe to administer Digoxin. If the heart rate is too low (bradycardia), administering Digoxin could potentially cause further complications. Therefore, assessing the apical pulse beforehand is a critical step in ensuring the safe administration of Digoxin.

Correct Answer: D

Rationale: The statement "Dextran therapy can cause anaphylaxis or renal failure" is true. Dextran is a type of colloid solution that can cause allergic reactions such as anaphylaxis in some individuals. It can also lead to kidney damage, which is why monitoring for signs of renal failure is crucial when administering Dextran. As a result of these potential risks, dextran therapy should be used cautiously and patients should be closely monitored for adverse reactions.

Correct Answer: A

Rationale: Metoclopramide, a D2 antagonist, causes acute dystonia (e.g., oculogyric crisis). Procyclidine, an anticholinergic, rapidly reverses this IV, relaxing muscles, a suitable treatment. Benzhexol (trihexyphenidyl) works orally but is slower. Levodopa and bromocriptine, dopamine agonists, treat Parkinson's, not dystonia from dopamine blockade. Risperidone worsens it. IV procyclidine's speed is critical in acute settings, restoring normal movement effectively.

Correct Answer: A

Rationale: The correct way to teach a new staff nurse to obtain a blood sample from a patient with a Portacath is to provide step-by-step instructions and demonstration. Using a Portacath requires specific knowledge and technique to prevent complications such as clot formation or infection. It is important for the preceptor nurse to properly guide and supervise the new staff nurse to ensure patient safety and accurate sample collection.
