C: Intramuscularly This route is not ideal for phenytoin due to potential variable absorption rates and the risk of tissue irritation, which can hinder effective seizure management.
Correct Answer: D
Rationale: Phenytoin should be administered intravenously. This method ensures rapid therapeutic levels and effective seizure control, aligning with the guidelines for emergency treatment of seizure disorders, where immediate action is paramount.
A: Intradermally This method is unsuitable for phenytoin administration, as intradermal injections are primarily used for allergy tests and local anesthetics, not for systemic therapeutic effects.
B: Subcutaneously Subcutaneous administration is inappropriate for phenytoin, as it can lead to slow absorption and inadequate serum levels, compromising the medication's efficacy in managing seizures.
C: Intramuscularly This route is not ideal for phenytoin due to potential variable absorption rates and the risk of tissue irritation, which can hinder effective seizure management.
Question 23
Regular
The primary health care provider prescribes diazepam 10 mg IV to be administered to a client to control his seizures. The nurse would administer this drug over which time frame?
Correct!
Incorrect
The correct answer is: B
Rationale
B: The nurse would administer diazepam 10 mg IV over 2 minutes to ensure safe and effective delivery. This timing allows for proper absorption and reduces the risk of adverse reactions during administration.
A: 1 minute Rapid administration may lead to increased side effects or complications, such as respiratory depression, which is not ideal for a patient experiencing seizures.
C: 5 minutes Lengthening the administration time unnecessarily may delay seizure control, which could put the patient at risk for further neurological compromise during critical moments.
D: 10 minutes An extended administration timeframe could hinder the prompt therapeutic effect needed in urgent situations, especially when immediate seizure control is essential for patient safety.

Question 24
Regular
Assessment of a client receiving anticonvulsant therapy reveals the following: sore throat, chills, fever, gingival bleeding, and bruising. Which nursing diagnosis would the nurse most likely identify?
Correct!
Incorrect
The correct answer is: D
Rationale
Risk for Infection. The client's symptoms of sore throat, chills, fever, gingival bleeding, and bruising indicate a possible infection, particularly as these signs suggest a compromised immune response, likely due to the anticonvulsant therapy.
A: Risk for Impaired Skin Integrity. While bruising may suggest skin integrity issues, the more pressing concern of infection is highlighted by the systemic symptoms present in the client.
B: Impaired Oral Mucous Membranes. Although gingival bleeding points to oral issues, the overarching symptoms of fever and chills align more closely with an infection than with localized mucosal impairment.
C: Risk for Injury. The symptoms presented do not directly correlate with an increased risk of injury, as they primarily indicate a potential infection rather than concerns related to physical safety or harm.

Question 25
Multiple Choice
A nurse is developing a plan of care for a client receiving anticonvulsant therapy and identifies a nursing diagnosis of Risk for Injury. Which assessment findings would support this nursing diagnosis? Select all that apply.
Correct!
Incorrect
The correct answer is: B,C,D
Rationale
Reports of blurred vision, complaints of dizziness, and photosensitivity support the nursing diagnosis of Risk for Injury as these symptoms can lead to impaired coordination, visual disturbances, and increased sensitivity to light, heightening the risk of accidents.
A: Epistaxis This condition involves bleeding from the nose, which does not directly indicate an increased risk of injury related to anticonvulsant therapy side effects.
E: Scaling red rash While this may indicate an adverse reaction, it does not inherently suggest a risk of injury or impaired safety in the patient.

Question 26
Multiple Choice
A client comes to the clinic for a follow-up visit. The client is prescribed lamotrigine for seizure control. The nurse suspects that the client may be experiencing Stevens-Johnson syndrome based on which of the following?
Correct!
Incorrect
The correct answer is: A,B,C
Rationale
Lesions on the mucous membranes indicate a serious skin condition, such as Stevens-Johnson syndrome, which can occur as a side effect of lamotrigine. This symptom raises concern for potential life-threatening reactions, warranting immediate medical evaluation and intervention.
A: Complaints of muscle pain do not specifically indicate Stevens-Johnson syndrome, as this symptom is more general and could relate to various conditions unrelated to the medication.
D: Recurrence of seizure activity does not signal Stevens-Johnson syndrome. Instead, it suggests inadequate seizure control, which may necessitate dosage adjustments or alternative medications for better management.
E: Dizziness is a common side effect of many medications, including lamotrigine, and does not specifically point to Stevens-Johnson syndrome, failing to highlight the critical skin-related symptoms associated with the condition.
