Nursing Elites

1. A nurse is caring for a client who is in preterm labor and is receiving magnesium sulfate via IV infusion. Which of the following findings indicates magnesium toxicity?

• A. Blood glucose of 150 mg/dL
• B. Urine output of 20 mL/hour
• C. Systolic blood pressure of 140 mm Hg
• D. BUN 20 mg/dL

Correct answer: B

Rationale: The correct answer is B. A urine output of 20 mL/hour is a sign of magnesium toxicity because decreased urine output can lead to accumulation of magnesium. Choices A, C, and D are not indicators of magnesium toxicity. Elevated blood glucose, high systolic blood pressure, and normal BUN levels do not specifically point towards magnesium toxicity.

2. A healthcare professional is assessing a client in the PACU. Which finding indicates decreased cardiac output?

• A. Shivering
• B. Oliguria
• C. Bradypnea
• D. Constricted pupils

Correct answer: B

Rationale: The correct answer is B: Oliguria. Oliguria (low urine output) is a sign of decreased cardiac output because the kidneys are not receiving enough blood to produce an adequate amount of urine. Shivering (choice A) is a response to hypothermia or the body's attempt to generate heat. Bradypnea (choice C) refers to abnormally slow breathing rate and is not directly related to cardiac output. Constricted pupils (choice D) are more indicative of conditions affecting the nervous system or medications.

3. A nurse is obtaining the medical history of a client who has a new prescription for isosorbide mononitrate. Which of the following should the nurse identify as a contraindication to this medication?

• A. Glaucoma
• B. Hypertension
• C. Polycythemia
• D. Migraine headaches

Correct answer: A

Rationale: Isosorbide mononitrate is contraindicated in clients with glaucoma due to its potential to increase intraocular pressure, which can exacerbate the condition. Hypertension, polycythemia, and migraine headaches are not contraindications for isosorbide mononitrate. In fact, isosorbide mononitrate is commonly used in the management of hypertension and certain types of angina.

4. A client with a new prescription for an albuterol metered-dose inhaler is being taught by a nurse. Which of the following instructions should the nurse include in the teaching?

• A. Inhale quickly when using the inhaler.
• B. Hold your breath for 10 seconds after inhaling the medication.
• C. Take a second puff of the inhaler immediately after the first.
• D. Exhale fully after using the inhaler.

Correct answer: B

Rationale: The correct instruction is to hold your breath for 10 seconds after inhaling the medication. This allows the medication to settle in the lungs and maximize its effectiveness. Choice A is incorrect as inhaling quickly may lead to improper medication delivery. Choice C is wrong because taking a second puff immediately after the first without waiting for the prescribed interval may cause an overdose. Choice D is also incorrect as exhaling fully after using the inhaler may result in the medication being exhaled rather than absorbed by the lungs.

5. A nurse enters a client's room and sees smoke coming from the trash can. Which of the following actions should the nurse take first?

• A. Close the window
• B. Evacuate the room
• C. Call the fire department
• D. Attempt to extinguish the fire

Correct answer: B

Rationale: The correct answer is to evacuate the room first. In a fire situation, the priority is safety, following the RACE protocol: Rescue, Alarm, Contain, Extinguish. Evacuating the room ensures the safety of both the client and the nurse. Closing the window (Choice A) can wait until after evacuation when there is no immediate danger. Calling the fire department (Choice C) is important but comes after ensuring personal safety and evacuating. Attempting to extinguish the fire (Choice D) is not recommended as it can put the nurse and the client at risk; firefighting should be left to professionals.
