Nursing Elites

1. When can a woman who thinks she may be pregnant use a home pregnancy test to diagnose pregnancy?

• A. A home pregnancy test can be used right after your first missed period.
• B. These tests are most accurate after you have missed your second period.
• C. Home pregnancy tests often give false positives and should not be trusted.
• D. The test can provide accurate information when used right after ovulation.

Correct answer: A

Rationale: The correct answer is A. Home pregnancy tests detect hCG, a hormone produced during pregnancy, and are most accurate after the first missed period when hCG levels are higher. Testing too early may result in a false negative. Waiting until after the first missed period increases the reliability of the test results. Choice B is incorrect as waiting until after the second missed period is unnecessary and may delay seeking appropriate healthcare. Choice C is incorrect as home pregnancy tests are generally reliable when used correctly. Choice D is incorrect because ovulation occurs before the period, and testing immediately after ovulation may not provide accurate results.

2. The healthcare provider prescribes Amoxicillin 500mg PO every 8hrs for a child who weighs 22 pounds. The available suspension is labeled Amoxicillin Suspension 250mg/5ml. The recommended maximum dose is 50mg/kg/24hr. How many mL should the nurse administer in a single dose based on the child’s weight?

• A. 10mL
• B. 15mL
• C. 7.5mL
• D. 5mL

Correct answer: A

Rationale: To calculate the dose for the child weighing 22 pounds, first convert the weight to kg: 22 lbs ÷ 2.2 = 10 kg. The maximum dose based on weight would be 10 kg × 50 mg/kg/24hr = 500 mg/24hr. Since the medication is prescribed every 8 hours, the dose for each administration would be 500 mg ÷ 3 doses = 166.67 mg. As the available suspension is 250mg/5ml, the nurse should administer 166.67 mg ÷ 250 mg/mL = 0.67 mL per dose. However, since it's not practical to administer a fraction of a milliliter, the nurse should round up to the nearest appropriate dose, which is 10mL.

3. The nurse instructs a laboring client to use accelerated-blow breathing. The client begins to complain of tingling fingers and dizziness. What action should the nurse take?

• A. Administer oxygen by face mask.
• B. Notify the healthcare provider of the client's symptoms.
• C. Have the client breathe into her cupped hands.
• D. Check the client's blood pressure and fetal heart rate.

Correct answer: C

Rationale: Tingling fingers and dizziness are symptoms of hyperventilation, which can occur with accelerated-blow breathing. Instructing the client to breathe into her cupped hands can help rebreathe exhaled carbon dioxide, which can alleviate the symptoms by restoring the proper balance of oxygen and carbon dioxide in the blood. This intervention can be effective in managing the client's hyperventilation without the need for additional medical interventions at this point.

4. Just after delivery, a new mother tells the nurse, 'I was unsuccessful breastfeeding my first child, but I would like to try with this baby.' Which intervention is best for the LPN/LVN to implement first?

• A. Assess the husband's feelings about his wife's decision to breastfeed their baby.
• B. Ask the client to describe why she was unsuccessful with breastfeeding her last child.
• C. Encourage the client to develop a positive attitude about breastfeeding to help ensure success.
• D. Provide assistance to the mother to begin breastfeeding as soon as possible after delivery.

Correct answer: D

Rationale: The correct intervention is to provide immediate assistance to the mother to begin breastfeeding as soon as possible after delivery. This approach helps initiate bonding and successful breastfeeding. Taking action promptly can address the mother's desire to breastfeed and promote positive outcomes for both the mother and the newborn.

5. A 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?

• A. 75ml/hr
• B. 100ml/hr
• C. 50ml/hr
• D. 25ml/hr

Correct answer: A

Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.
