Nursing Elites

1. A nurse is caring for a client in preterm labor who is receiving magnesium sulfate. Which of the following is an indication of magnesium toxicity?

• A. Blood glucose of 160 mg/dL
• B. Urine output of 20 mL/hour
• C. Systolic BP of 140 mm Hg
• D. Respiratory rate of 20/min

Correct answer: B

Rationale: The correct answer is B: Urine output of 20 mL/hour. Urine output below 30 mL/hour is a sign of magnesium toxicity due to the risk of accumulation in the body. Choices A, C, and D are not indicative of magnesium toxicity. Elevated blood glucose, systolic blood pressure, and normal respiratory rate are not specific signs of magnesium toxicity.

2. A nurse is assessing four clients for fluid balance. Which of the following clients is exhibiting manifestations of dehydration?

• A. A client who has a urine specific gravity of 1.010.
• B. A client who has a weight gain of 2.2 kg (2 lb) in 24 hr.
• C. A client who has a hematocrit of 45%.
• D. A client who has a temperature of 39°C (102°F).

Correct answer: D

Rationale: The correct answer is D because an elevated temperature is a common manifestation of dehydration. Choices A, B, and C are not indicative of dehydration. A urine specific gravity of 1.010 is within normal range, weight gain suggests fluid overload, and a hematocrit of 45% is also within normal limits and not specifically related to dehydration.

3. A nurse should teach which of the following clients requiring crutches about how to use a three-point gait?

• A. A client who is able to bear full weight on both lower extremities.
• B. A client who has bilateral leg braces due to paralysis of the lower extremities.
• C. A client who has a right femur fracture with no weight bearing on the affected leg.
• D. A client who has bilateral knee replacements with partial weight bearing on both legs.

Correct answer: C

Rationale: The correct answer is C because a three-point gait is used when the client can bear full weight on one foot and uses crutches and the uninvolved leg to ambulate. Choices A, B, and D are incorrect because they do not meet the criteria for using a three-point gait. Choice A states that the client can bear full weight on both lower extremities, which does not require a three-point gait. Choice B mentions bilateral leg braces due to paralysis, which would not involve using a three-point gait. Choice D describes a client with bilateral knee replacements with partial weight bearing, which also does not align with the use of a three-point gait.

4. A healthcare provider is educating a client about the use of montelukast. Which of the following should be included?

• A. It is used for acute asthma attacks
• B. It is taken once daily in the evening
• C. It should be taken with food
• D. It has no side effects

Correct answer: B

Rationale: The correct answer is B. Montelukast is a leukotriene receptor antagonist that is typically taken once daily in the evening for asthma management. Choice A is incorrect as montelukast is not used for acute asthma attacks but rather for the prevention of asthma symptoms. Choice C is also incorrect because montelukast can be taken with or without food. Choice D is misleading as all medications, including montelukast, have potential side effects.

5. A nurse is assessing a client for signs of hypokalemia. Which of the following findings should the nurse look for?

• A. Muscle weakness
• B. Weight gain
• C. Elevated blood pressure
• D. Increased thirst

Correct answer: A

Rationale: Muscle weakness is a classic sign of hypokalemia. Potassium plays a crucial role in muscle function, and low potassium levels can lead to muscle weakness. Weight gain, elevated blood pressure, and increased thirst are not typically associated with hypokalemia. Weight gain can be seen in conditions like fluid retention, elevated blood pressure can result from various causes, and increased thirst may be a symptom of conditions like diabetes.
