Nursing Elites

1. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?

• A. 5
• B. 10
• C. 15
• D. 20

Correct answer: A

Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.

2. A client prescribed warfarin is being taught about dietary modifications by a nurse. Which statement by the client indicates understanding of the teaching?

• A. ''I need to avoid foods high in vitamin C.''
• B. ''I should eat a consistent amount of vitamin K each day.''
• C. ''I can eat as many leafy greens as I want.''
• D. ''I should not worry about any changes in my diet.''

Correct answer: B

Rationale: The correct answer is B. Consistency in vitamin K intake is crucial for clients on warfarin to maintain stable anticoagulation levels. Option A is incorrect as vitamin C does not directly interact with warfarin. Option C is incorrect because although leafy greens are high in vitamin K, excessive consumption can affect warfarin's effectiveness. Option D is incorrect as any changes in diet, particularly in vitamin K intake, can impact the efficacy of warfarin.

3. Following morning care, a client with C-5 spinal cord injury who is sitting in a wheelchair becomes flushed and complains of a headache. Which intervention should the nurse implement first?

• A. Check for any kinks or obstructions in the client’s Foley tubing
• B. Assess the client’s blood pressure every 15 minutes
• C. Administer a prescribed PRN dose of hydralazine (Apresoline)
• D. Educate the client on recognizing symptoms of dysreflexia

Correct answer: B

Rationale: In a client with a C-5 spinal cord injury experiencing flushing and a headache, the priority intervention is to assess the client's blood pressure every 15 minutes. These symptoms could indicate autonomic dysreflexia, a potentially life-threatening condition. Assessing the blood pressure is crucial to identify and address this emergency situation promptly. Checking for kinks or obstructions in the Foley tubing (Choice A) is important but not the priority in this scenario. Administering hydralazine (Choice C) without knowing the blood pressure could be harmful as it may lead to a sudden drop in blood pressure. Educating the client on recognizing symptoms of dysreflexia (Choice D) is important for long-term management but is not the immediate action needed in this acute situation.

4. Which client requires careful nursing assessment for signs and symptoms of hypomagnesemia?

• A. A young adult client with intractable vomiting from food poisoning
• B. A client who developed hyperparathyroidism in late adolescence
• C. A middle-aged male client in renal failure following an unsuccessful kidney transplant
• D. A female client who is overzealous with her intake of simple carbohydrates

Correct answer: A

Rationale: The correct answer is A. Vomiting can lead to significant loss of magnesium, causing hypomagnesemia. In this scenario, the young adult client with intractable vomiting from food poisoning is at higher risk of developing hypomagnesemia due to the loss of magnesium through vomiting. Choices B, C, and D are less likely to present with hypomagnesemia. Hyperparathyroidism (B) is associated with hypercalcemia, renal failure (C) can lead to hypermagnesemia, and overconsumption of simple carbohydrates (D) is not directly linked to magnesium imbalances.

5. While flushing the proximal port of a triple lumen central venous catheter with heparin solution, the nurse meets resistance. What action should the nurse take?

• A. Remove the cap and apply direct gentle pressure with the syringe
• B. Contact the healthcare provider regarding the need for a chest x-ray
• C. Cover the cap with tape and label the port as being obstructed
• D. Remove the catheter while applying gentle pressure at the insertion site

Correct answer: B

Rationale: When encountering resistance while flushing a central venous catheter, it is crucial to contact the healthcare provider regarding the need for a chest x-ray. This resistance may indicate a blockage within the catheter, a kink, or other issues that could compromise the integrity of the catheter or pose a risk to the patient. It is essential to assess the situation through imaging to determine the appropriate course of action. Option A is incorrect because applying direct pressure could cause damage to the catheter or dislodge any potential blockage. Option C is incorrect as labeling the port as obstructed without further assessment may delay necessary interventions. Option D is incorrect as removing the catheter without proper evaluation can lead to complications and should only be done under the guidance of a healthcare provider.
