Nursing Elites

1. A client is receiving warfarin for atrial fibrillation. Which of the following laboratory tests should the nurse expect to be ordered to monitor the effect of warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Prothrombin time (PT)
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). When a client is on warfarin therapy, the INR is monitored regularly to assess the anticoagulant effects of the medication. A therapeutic INR range for most indications is between 2.0 to 3.0. Choices A, C, and D are not typically used to monitor the effect of warfarin. Platelet count assesses the number of platelets in the blood, PT measures the clotting time of plasma, and PTT evaluates the intrinsic pathway of coagulation.

2. The healthcare provider is reviewing the medical record of a client who is requesting combination oral contraceptives. Which of the following conditions in the client's history is a contraindication to the use of oral contraceptives?

• A. Hyperthyroidism
• B. Thrombophlebitis
• C. Diverticulosis
• D. Hypocalcemia

Correct answer: B

Rationale: Thrombophlebitis is a condition characterized by inflammation of a vein, which increases the risk of blood clots. The use of oral contraceptives further elevates the risk of clot formation, making them contraindicated in individuals with thrombophlebitis. Hyperthyroidism (Choice A), diverticulosis (Choice C), and hypocalcemia (Choice D) are not contraindications to the use of oral contraceptives.

3. When managing blood pressure at home, which statement by the client indicates an understanding of the teaching provided by a nurse for hypertension?

• A. I will take my medication only when I feel dizzy.
• B. I will check my blood pressure at least once a week.
• C. I will stop taking my medication once my blood pressure is within normal range.
• D. I will sit quietly for 5 minutes before measuring my blood pressure.

Correct answer: D

Rationale: The correct answer is D because sitting quietly for 5 minutes before measuring blood pressure ensures an accurate reading and helps monitor hypertension. Choice A is incorrect as medications for hypertension should be taken as prescribed, not based on symptoms like dizziness. Choice B is not ideal as blood pressure should be checked more frequently, preferably daily. Choice C is incorrect as stopping medication abruptly once blood pressure is normal can lead to rebound hypertension.

4. While caring for a client with an arterial line, which of the following actions should the nurse take?

• A. Level the transducer with the client's phlebotomy site
• B. Flush the arterial line every 8 hours
• C. Obtain a blood sample for arterial blood gases
• D. Keep the client's hand elevated above the heart level

Correct answer: C

Rationale: Obtaining arterial blood gases is a crucial nursing action when caring for a client with an arterial line. This procedure helps assess the client's oxygenation status and acid-base balance accurately. Leveling the transducer with the client's phlebotomy site (A) is important for accurate pressure measurements, but it is not the primary action in this scenario. Flushing the arterial line every 8 hours (B) is a routine maintenance procedure and not the immediate priority. Keeping the client's hand elevated above the heart level (D) is a good practice to prevent swelling, but it is not directly related to the arterial line care in this case.

5. A nurse is reviewing the medical record of a client who has chronic kidney disease. The client's potassium level is 6.5 mEq/L. Which of the following actions should the nurse take?

• A. Administer sodium bicarbonate
• B. Administer sodium polystyrene sulfonate
• C. Administer calcium gluconate
• D. Administer calcium carbonate

Correct answer: B

Rationale: The correct answer is B: Administer sodium polystyrene sulfonate. Sodium polystyrene sulfonate is used to treat hyperkalemia by promoting the excretion of potassium. Choice A, administering sodium bicarbonate, is incorrect as it is not used to treat hyperkalemia. Choice C, administering calcium gluconate, is incorrect as it is used to treat hypocalcemia, not hyperkalemia. Choice D, administering calcium carbonate, is incorrect as it is used to treat conditions like osteoporosis and indigestion, not hyperkalemia.
