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. A client at 32-weeks gestation comes to the prenatal clinic with complaints of pedal edema, dyspnea, fatigue, and a moist cough. Which question is most important for the LPN/LVN to ask this client?

• A. Which symptom did you experience first?
• B. Are you consuming large amounts of salty foods?
• C. Have you traveled to a foreign country recently?
• D. Do you have a history of rheumatic fever?

Correct answer: D

Rationale: The correct answer is D. Rheumatic fever can lead to rheumatic heart disease, which may be exacerbated during pregnancy, causing symptoms like pedal edema and dyspnea. Asking about a history of rheumatic fever is crucial in this case to assess the potential impact on the client's current symptoms. Choices A, B, and C are less relevant in this scenario as they do not directly relate to the presenting symptoms and history of rheumatic fever.

3. A client addicted to heroin and newly pregnant asks a nurse about ensuring her baby's health while on methadone. What should the nurse advise?

• A. Sign up for group therapy sessions.
• B. Discontinue the methadone right away.
• C. Start prenatal care as soon as possible.
• D. Describe genetic testing protocol.

Correct answer: C

Rationale: Initiating prenatal care promptly is essential for monitoring the well-being of both the mother and the fetus, particularly in high-risk pregnancies involving substance use. Early prenatal care allows for timely interventions, education, and support to promote a healthier pregnancy and birth outcomes. Choice A is incorrect because while group therapy may be beneficial, initiating prenatal care is more crucial at this stage. Choice B is incorrect as abrupt discontinuation of methadone can be harmful and should be managed under medical supervision. Choice D is incorrect as genetic testing is not the immediate priority in this scenario.

4. A client in active labor is admitted with preeclampsia. Which assessment finding is most significant in planning this client's care?

• A. Patellar reflex 4+
• B. Blood pressure 158/80
• C. Four-hour urine output 240 ml
• D. Respirations 12/minute

Correct answer: A

Rationale: The correct answer is A: 'Patellar reflex 4+'. Hyperreflexia is a sign of severe preeclampsia and increases the risk of seizures, indicating the need for immediate intervention. Monitoring and addressing this finding are crucial in managing the client's condition and preventing complications.

5. In assessing a 9-year-old boy admitted to the hospital with possible acute post-streptococcal glomerulonephritis (APSGN), what information is most significant to obtain in his history?

• A. Back pain for a few days
• B. A history of hypertension
• C. A sore throat last week
• D. Diuresis during the nights

Correct answer: C

Rationale: A recent sore throat is most significant in this case as it could indicate a preceding streptococcal infection, which is a crucial factor in diagnosing APSGN. Streptococcal infection often precedes APSGN, and recognizing this history is essential for appropriate management and treatment. Choices A, B, and D are less relevant in the context of APSGN. Back pain and diuresis are symptoms that may not directly correlate with APSGN, while a history of hypertension, although important in general health assessment, is not as specific to the current scenario compared to a recent sore throat.
