Nursing Elites

1. 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.

2. At 20 weeks gestation, a client is scheduled for an ultrasound. In preparing the client for the procedure, the nurse should explain that the primary reason for conducting this diagnostic study is to obtain which information?

• A. Sex and size of the fetus.
• B. Chromosomal abnormalities.
• C. Fetal growth and gestational age.
• D. Lecithin-sphingomyelin ratio.

Correct answer: C

Rationale: The primary reason for an ultrasound at 20 weeks gestation is to assess fetal growth, gestational age, and anatomical development. This evaluation helps ensure the fetus is developing appropriately and can detect any potential issues that may require intervention. Choices A, B, and D are incorrect because at 20 weeks, the primary focus of the ultrasound is not to determine the sex of the fetus, detect chromosomal abnormalities, or assess the lecithin-sphingomyelin ratio. While these factors may be evaluated in pregnancy, they are not the primary reasons for an ultrasound at 20 weeks gestation.

3. A breastfeeding infant, screened for congenital hypothyroidism, is found to have low levels of thyroxine (T4) and high levels of thyroid-stimulating hormone (TSH). What is the best explanation for this finding?

• A. The thyroxine level is low because the TSH level is high.
• B. High thyroxine levels do not normally occur in breastfeeding infants.
• C. The thyroid gland does not produce normal levels of thyroxine for several weeks after birth.
• D. The TSH is high because of the low production of T4 by the thyroid.

Correct answer: D

Rationale: High TSH and low T4 levels indicate that the thyroid gland is not producing enough hormones, which is a sign of congenital hypothyroidism. In this case, the high TSH is a compensatory response by the body to stimulate the thyroid to produce more T4. Choice A is incorrect because TSH does not directly affect T4 levels; rather, it is the other way around where low T4 levels lead to high TSH levels. Choice B is incorrect because high thyroxine levels are not expected in congenital hypothyroidism. Choice C is incorrect as the thyroid gland should be producing normal levels of thyroxine shortly after birth, making this explanation unlikely in the context of congenital hypothyroidism.

4. The nurse is caring for a client who experienced fetal demise at 32 weeks' gestation. After the fetus is delivered vaginally, the nurse implements fetal demise protocol and identification procedures. Which action is most important for the nurse to take?

• A. Create a memory box with the baby's footprint and photographs.
• B. Determine if the mother desires a visit from her clergy.
• C. Encourage the mother to hold and spend time with her baby.
• D. Explain the reasons for obtaining consent for an infant autopsy.

Correct answer: C

Rationale: Encouraging the mother to hold and spend time with her baby is crucial after a fetal demise at 32 weeks' gestation. This action can support the mother in the grieving process, facilitate bonding, and provide closure, helping her cope with the loss of the baby. Creating a memory box with the baby's footprint and photographs could be emotionally comforting but not as immediate and impactful as encouraging direct physical contact. While offering a visit from her clergy may provide spiritual support, the immediate need is to address the physical and emotional aspects of the situation. Explaining the reasons for obtaining consent for an infant autopsy is important, but it is secondary to the immediate emotional support needed by the mother.

5. The nurse is assessing a newborn who was precipitously delivered at 38 weeks' gestation. The newborn is tremulous, tachycardic, and hypertensive. Which assessment action is most important for the nurse to take?

• A. Perform a gestational age assessment.
• B. Obtain a drug screen for cocaine.
• C. Determine reactivity of neonatal reflexes.
• D. Weigh and measure the newborn.

Correct answer: B

Rationale: The correct answer is to obtain a drug screen for cocaine. Tremulousness, tachycardia, and hypertension in a newborn can be signs of neonatal abstinence syndrome, often caused by maternal drug use, such as cocaine. Identifying maternal drug use is crucial for appropriate management and treatment of the newborn.
