Nursing Elites

1. The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for a client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?

• A. 150 mL/hour
• B. 250 mL/hour
• C. 50 mL/hour
• D. 275 mL/hour

Correct answer: A

Rationale: To calculate the infusion rate, first, determine the total volume to be infused (6 grams of magnesium sulfate) over a specific time frame (20 minutes). Then, calculate the concentration of magnesium sulfate in the IV bag to determine the mL/hour rate. The IV bag contains 20 grams of magnesium sulfate in 500 mL of solution, which means there are 4 grams of magnesium sulfate per 100 mL. Since 6 grams are required, the nurse should set the pump to deliver 150 mL/hour to infuse the prescribed dose over 20 minutes. Choice B, 250 mL/hour, is incorrect because it miscalculates the amount of magnesium sulfate infused per hour. Choice C, 50 mL/hour, is incorrect as it is too slow to deliver the required dose in the specified time frame. Choice D, 275 mL/hour, is incorrect as it overestimates the infusion rate and would deliver the dose too quickly.

2. In caring for a 4-year-old boy recently diagnosed with Duchenne muscular dystrophy (DMD), which characteristic of the disease is most important for the nurse to focus on during the initial teaching?

• A. Lower legs become progressively weaker, causing a waddling, unsteady gait.
• B. Growth and development have been abnormal since birth.
• C. Muscular strength can be regained with physical exercise and therapy.
• D. Respiratory dysfunction and aspiration are prime concerns at this stage of the disease.

Correct answer: A

Rationale: In Duchenne muscular dystrophy, a key characteristic is the progressive weakness in the lower legs, leading to a waddling, unsteady gait. The nurse should focus on teaching about this aspect as it helps in understanding the disease's progression and managing the symptoms effectively.

3. A 6-year-old child is diagnosed with rheumatic fever and demonstrates associated chorea (sudden aimless movements of the arms and legs). Which information should the nurse provide to the parents?

• A. Muscle tension decreases with fine motor skill projects, so these activities should be encouraged.
• B. The chorea or movements are temporary and will eventually disappear.
• C. Permanent lifestyle changes are not needed to promote safety in the home.
• D. Consistent discipline is not directly related to controlling the movements.

Correct answer: B

Rationale: Chorea, or sudden aimless movements associated with rheumatic fever, is temporary in nature and will eventually disappear on its own. It is important for the nurse to reassure the parents that these movements are part of the condition and typically resolve over time without the need for permanent lifestyle changes or strict discipline. Providing accurate information and reassurance to the parents can help alleviate concerns and promote understanding of the condition's course. Choices A, C, and D are incorrect because muscle tension, permanent lifestyle changes, and consistent discipline are not directly related to the resolution of chorea in rheumatic fever.

4. After two miscarriages, a client is instructed to increase her daily intake of foods that include folic acid. The client does not like green leafy vegetables and states she is allergic to soy. Which food should the nurse suggest that the client eat to obtain folic acid?

• A. Strawberries.
• B. Yogurt.
• C. Collard greens.
• D. Whole milk.

Correct answer: C

Rationale: Collard greens are a good source of folic acid, which is important for preventing neural tube defects, especially in clients with a history of miscarriages. Since the client does not like green leafy vegetables, collard greens could be suggested as an alternative source of folic acid. Yogurt and whole milk do not contain significant amounts of folic acid, and while strawberries are a healthy choice, they are not a high source of folic acid compared to collard greens.

5. A 28-year-old client in active labor complains of cramps in her leg. What intervention should be implemented?

• A. Massage the calf and foot.
• B. Extend the leg and dorsiflex the foot.
• C. Lower the leg off the side of the bed.
• D. Elevate the leg above the heart.

Correct answer: B

Rationale: During active labor, if a client complains of leg cramps, extending the leg and dorsiflexing the foot can help relieve the muscle cramps by stretching the affected muscles. This intervention promotes circulation and can alleviate discomfort associated with leg cramps.
