1. At 1200, the practical nurse learns that a client's 0900 dose of an anticonvulsant was not given. The next scheduled dose is at 2100. Which action should the PN take?
- A. Administer half of the missed dose immediately
- B. Administer the missed dose as soon as possible
- C. Give the missed dose with the next scheduled dose
- D. Withhold the missed dose unless seizure activity occurs
Correct answer: B
Rationale: Administering the missed dose as soon as possible is crucial in this situation. Missing an anticonvulsant dose can lead to breakthrough seizures, which are harmful to the client. Administering the missed dose promptly helps maintain the therapeutic level of the medication and reduces the risk of seizure activity. Giving half the dose may not provide adequate protection against seizures. Delaying the dose until the next scheduled time increases the time the client is without the medication, potentially increasing the risk of seizures. Withholding the missed dose unless seizure activity occurs is not recommended, as prevention is key in managing anticonvulsant therapy.
2. An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units in the morning. Which finding should the nurse document as evidence that the amount of insulin is inadequate?
- A. States that her feet are constantly cold and numb
- B. A wound on the ankle that starts to drain and becomes painful
- C. Consecutive evening serum glucose greater than 260 mg/dL
- D. Reports nausea in the morning but still able to eat breakfast
Correct answer: C
Rationale: The correct answer is C. Consistently high evening glucose levels indicate that the current insulin dosage is inadequate to maintain proper glucose control. Choice A is incorrect because cold and numb feet are more indicative of peripheral vascular disease rather than inadequate insulin dosage. Choice B describes a wound that may be related to poor circulation or neuropathy but not necessarily inadequate insulin dosage. Choice D suggests gastrointestinal issues that are not directly related to insulin dosage adequacy.
3. What is the primary cause of diabetic ketoacidosis (DKA)?
- A. Insulin deficiency
- B. Overhydration
- C. Excess carbohydrate intake
- D. Excess insulin
Correct answer: A
Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.
4. You are teaching students about how hyperosmotic agents (osmotic diuretics) are used to treat intracranial pressure. Which of the following is NOT one of the functions of hyperosmotic agents?
- A. Reduces brain metabolism and systemic blood pressure
- B. Reduces cerebral edema
- C. Dehydrates the brain
- D. Draws fluids from extravascular spaces into the plasma
Correct answer: A
Rationale: Hyperosmotic agents primarily work by reducing cerebral edema, dehydrating the brain, and drawing fluids from extravascular spaces into the plasma. However, they do not have a direct effect on reducing brain metabolism or systemic blood pressure. Therefore, the correct answer is A. Choice B is correct as hyperosmotic agents do help in reducing cerebral edema. Choice C is accurate as hyperosmotic agents dehydrate the brain. Choice D is also true as these agents draw fluids from extravascular spaces into the plasma.
5. An 8-year-old child is placed in 90-90 traction for a fractured femur. The nurse notices that the weights are touching the foot of the bed. What action should the nurse take?
- A. No bowel movement for two days
- B. Mother helps reposition the child
- C. Ensure weights are not touching the foot of the bed
- D. Child wiggles toes freely when tickled
Correct answer: C
Rationale: The nurse should ensure that the weights in traction are not touching the foot of the bed. This is crucial to maintain proper alignment and effectiveness of the traction. When the weights touch the bed, it can compromise the traction's function and delay healing. Choices A, B, and D are incorrect as they do not address the issue of ensuring that the weights are not touching the bed, which is essential for the traction to work effectively.
