Nursing Elites

1. A healthcare professional is reviewing the medical record of a client scheduled for a CT scan with contrast media. The healthcare professional should identify which of the following findings as a contraindication to the procedure?

• A. White blood cell count of 6,000/mm³
• B. Urine specific gravity of 1.025
• C. History of asthma
• D. History of allergy to shellfish

Correct answer: D

Rationale: The correct answer is D, a history of allergy to shellfish. A known allergy to shellfish is a contraindication for the use of contrast media in a CT scan due to the potential risk of an allergic reaction, which could be severe and life-threatening. Choices A, B, and C are not contraindications to the procedure. A normal white blood cell count, urine specific gravity within the normal range, and a history of asthma do not typically interfere with the administration of contrast media for a CT scan.

2. A nurse is assessing a client who has a history of seizure disorder and is receiving phenytoin. Which of the following findings should the nurse identify as an adverse effect of the medication?

• A. Bradycardia.
• B. Ataxia.
• C. Tachycardia.
• D. Insomnia.

Correct answer: B

Rationale: The correct answer is B: Ataxia. Ataxia, which refers to uncoordinated movements, is a common adverse effect of phenytoin, a medication used to manage seizure disorders. Bradycardia (Choice A) is not typically associated with phenytoin; instead, it may cause tachycardia (Choice C) as a side effect. Insomnia (Choice D) is not a common adverse effect of phenytoin.

3. 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.

4. A client at 10 weeks of gestation reports frequent nausea and vomiting. Which of the following instructions should the nurse include?

• A. Eat high-protein foods.
• B. Lie down after meals.
• C. Drink water with meals.
• D. Eat dry carbohydrates before getting out of bed.

Correct answer: D

Rationale: During early pregnancy, nausea and vomiting are common. Instructing the client to eat dry carbohydrates like crackers before getting out of bed can help alleviate these symptoms. This recommendation helps prevent an empty stomach, which can worsen nausea. High-protein foods (Choice A) may be harder to digest and could exacerbate nausea. Lying down after meals (Choice B) may increase gastric reflux and worsen symptoms. Drinking water with meals (Choice C) may make the client feel fuller, potentially worsening nausea.

5. Which electrolyte imbalance is most concerning in a patient on furosemide?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: B

Rationale: The correct answer is Hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion by increasing its excretion in the urine. Hypokalemia is a common and concerning side effect of furosemide therapy. Hyperkalemia (Choice A) is less likely as furosemide tends to lower potassium levels. Hyponatremia (Choice C) is more commonly seen with thiazide diuretics. Hypercalcemia (Choice D) is not directly associated with furosemide use.
