Nursing Elites

1. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

2. A client who fell 20 feet from the roof of his home has multiple injuries, including a right pneumothorax. Chest tubes were inserted in the emergency department prior to his transfer to the intensive care unit (ICU). The nurse observes that the suction control chamber is bubbling at the -10 cm H20 mark, with fluctuation in the water seal, and over the past hour, 75 mL of bright red blood is measured in the collection chamber. Which intervention should the nurse implement?

• A. Increase wall suction to eliminate fluctuation in the water seal.
• B. Give blood from the collection chamber as autotransfusion.
• C. Add sterile water to the suction control chamber.
• D. Manipulate blood in tubing to drain into chamber.

Correct answer: C

Rationale: The correct intervention for the nurse to implement is to add sterile water to the suction control chamber. This action helps maintain the proper functioning of the chest tube system by regulating the negative pressure. Increasing wall suction is not recommended as it could lead to excessive negative pressure. Giving blood from the collection chamber as autotransfusion is inappropriate and poses a risk of complications such as air embolism. Manipulating blood in the tubing is also unsafe as it could introduce air into the system, increasing the risk of complications for the client.

3. 4 hours after administration of 20U of regular insulin, the client becomes shaky and diaphoretic. What action should the nurse take?

• A. Encourage the client to eat crackers and milk
• B. Administer a PRN dose of 10U of regular insulin
• C. Give the client crackers and milk
• D. Record the client's reaction in the diabetic flow sheet

Correct answer: C

Rationale: The correct action for the nurse to take when a client becomes shaky and diaphoretic after insulin administration, indicating hypoglycemia, is to provide the client with carbohydrates like crackers and milk. Carbohydrates help raise blood glucose levels quickly. Encouraging the client to eat crackers and milk (Choice A) is the appropriate immediate action to address the hypoglycemia. Administering more insulin (Choice B) would worsen hypoglycemia, and recording the reaction (Choice D) is important but not the immediate action needed to treat the hypoglycemia.

4. The nurse is preparing to administer a tuberculin skin test (TST). Which area of the body is the preferred site for this injection?

• A. Deltoid muscle
• B. Inner forearm
• C. Abdomen
• D. Thigh

Correct answer: B

Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.

5. A client with a history of seizure disorder who is receiving phenytoin (Dilantin) is being discharged. Which instruction should the nurse provide?

• A. Take the medication at bedtime.
• B. Monitor drug levels regularly.
• C. Avoid alcohol while taking this medication.
• D. Take the medication at the same time every day.

Correct answer: B

Rationale: The correct answer is to instruct the client to monitor drug levels regularly. This is crucial for phenytoin (Dilantin) to ensure that the medication levels are within the therapeutic range and to prevent toxicity. Choice A, taking the medication at bedtime, is not specifically required for phenytoin administration. Choice C, avoiding alcohol, is generally a good practice with medications but is not as critical as monitoring drug levels for phenytoin. Choice D, taking the medication at the same time every day, is important for consistency but does not address the specific monitoring needs of phenytoin.
