Nursing Elites

1. A loading dose of terbutaline (Brethine) 250 mcg IV is prescribed for a client in preterm labor. Brethine 20 mg is added to 1,000 mL of D5W. How many milliliters of the solution should the nurse administer?

• A. 45
• B. 15 mL
• C. 4
• D. 13

Correct answer: D

Rationale: To calculate the amount of terbutaline to administer, first convert the dose to the same unit. 250 mcg = 0.25 mg. Next, set up a proportion: 20 mg is to 1000 mL as 0.25 mg is to X mL. Cross multiply and solve for X: 20 × X = 0.25 × 1000. X = (0.25 × 1000) / 20 = 12.5 mL. Therefore, the nurse should administer 13 mL of the solution. Choice A is incorrect as it does not reflect the correct calculation. Choice B is incorrect as it does not consider the accurate conversion and calculation. Choice C is incorrect as it is not the result of the correct proportion calculation.

2. A 4-year-old boy presents with a rash and is diagnosed with varicella (chickenpox). What is the most appropriate intervention to manage this condition?

• A. Administer oral acyclovir.
• B. Apply calamine lotion to soothe itching.
• C. Encourage scratching to relieve itching.
• D. Encourage bed rest to avoid spreading the rash.

Correct answer: B

Rationale: The most appropriate intervention for managing varicella (chickenpox) in a 4-year-old child is to apply calamine lotion to soothe itching. Calamine lotion helps alleviate the itching associated with the chickenpox rash, providing relief to the child. It is important to discourage scratching to prevent complications such as scarring or secondary bacterial infections. Encouraging bed rest can be beneficial for comfort but is not the primary intervention to manage chickenpox.

3. The healthcare provider prescribes terbutaline (Brethine) for a client in preterm labor. Before initiating this prescription, it is most important for the LPN/LVN to assess the client for which condition?

• A. Gestational diabetes.
• B. Elevated blood pressure.
• C. Urinary tract infection.
• D. Swelling in lower extremities.

Correct answer: A

Rationale: The correct answer is A: Gestational diabetes. Terbutaline (Brethine) is known to cause hyperglycemia, so it is crucial to assess for gestational diabetes before administering it. Assessing for elevated blood pressure (choice B), urinary tract infection (choice C), or swelling in lower extremities (choice D) is not directly related to the potential side effect of terbutaline in causing hyperglycemia.

4. When should the LPN/LVN encourage the laboring client to begin pushing?

• A. When there is only an anterior or posterior lip of the cervix left.
• B. When the client describes the need to have a bowel movement.
• C. When the cervix is completely dilated.
• D. When the cervix is completely effaced.

Correct answer: C

Rationale: The LPN/LVN should encourage the laboring client to begin pushing when the cervix is completely dilated to 10 centimeters. Pushing before full dilation can lead to cervical injury and ineffective labor progress. By waiting for complete dilation, the client can push effectively, aiding in the descent of the baby through the birth canal. Choices A, B, and D are incorrect because pushing before complete dilation can be harmful and may not effectively help in the descent of the baby. The presence of an anterior or posterior lip of the cervix, the urge to have a bowel movement, or complete effacement of the cervix are not indicators for the initiation of pushing during labor.

5. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperneic. Which action should the nurse implement first?

• A. Place the infant in a knee-chest position.
• B. Administer morphine sulfate.
• C. Start intravenous fluids.
• D. Provide 100% oxygen by face mask.

Correct answer: A

Rationale: In a tetralogy of Fallot situation, placing the infant in a knee-chest position is the initial priority to help increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation. This position can assist in optimizing oxygen levels before considering other interventions. Administering morphine sulfate (choice B) is not the first-line treatment for tetralogy of Fallot crisis. Starting intravenous fluids (choice C) may be necessary but is not the priority in this situation. Providing 100% oxygen by face mask (choice D) may not fully address the underlying issue of decreased systemic vascular resistance that leads to cyanosis in tetralogy of Fallot.
