Question 1 of 5
A client is prescribed phenytoin (Dilantin) for seizures. Which statement by the client indicates effective teaching?
Correct Answer: B
Rationale: Phenytoin risks gingival hyperplasia, making oral hygiene vital'brushing and flossing prevent this, showing teaching success. Alcohol increases seizure risk and drug levels. Milk reduces absorption via calcium binding. Stopping after a month risks recurrence, as seizures require long-term control. Regular dental care mitigates a common, chronic side effect, aligning with phenytoin's long-term use and metabolism (CYP450 saturation). This statement reflects understanding of self-care, critical for adherence and complication prevention, making B the indicator of effective education.
Question 2 of 5
Which is not one of the rights of medication administration?
Correct Answer: C
Rationale: The five rights of medication administration are: the right patient, the right drug, the right dose, the right route, and the right time. These are essential principles to ensure safe and effective medication administration. The attitude of the healthcare provider is important for delivering care, but it is not included as one of the fundamental rights of medication administration. It is important for healthcare providers to approach medication administration with professionalism, compassion, and attentiveness, but it is not considered one of the primary rights in the context of medication administration protocols.
Question 3 of 5
A 17-year-old client is taking phenytoin (Dilantin) for the treatment of seizures. Phenytoin blood level reveals to be 25 mcg/ml. Which of the following symptoms would be expected as a result of the laboratory result?
Correct Answer: D
Rationale: Phenytoin is an antiepileptic medication that is used to treat seizures. It has a narrow therapeutic range, and a blood level of 25 mcg/ml is considered to be high. At this level, patients are at risk for developing symptoms of phenytoin toxicity. Nystagmus, which is an involuntary rapid eye movement, is a common symptom of phenytoin toxicity. Other symptoms of phenytoin toxicity may include ataxia, diplopia, slurred speech, confusion, and drowsiness. It is important to monitor phenytoin blood levels regularly to avoid toxicity and adjust the dose accordingly.
Question 4 of 5
With regard to oral anti-asthmatic agents:
Correct Answer: C
Rationale: Prednisone is intermediate-acting (12-36 hours), not long-acting like dexamethasone, so that's false. Methotrexate benefits some prednisone-dependent asthmatics, not all studies, making that false. Cyclosporin's toxicity (e.g., nephrotoxicity) limits its anti-asthmatic use, a true statement, despite immunosuppressive potential. Nifedipine has minimal effect on exercise-induced bronchoconstriction, unlike inhaled CCBs, so that's false. Macrolides show some benefit in asthma. Cyclosporin's limitation reflects its risk-benefit profile, restricting its practical use.
Question 5 of 5
When monitoring a patient for signs of hypokalemia, the nurse looks for what early sign?
Correct Answer: D
Rationale: One of the early signs of hypokalemia is muscle weakness. Potassium plays a crucial role in maintaining normal muscle function, including the contraction of skeletal and smooth muscles. A deficiency in potassium can lead to muscle weakness, cramping, and fatigue. It is important for the nurse to monitor any signs of muscle weakness in a patient at risk for hypokalemia as it can progress to more severe complications if left untreated. Seizures and cardiac dysrhythmias are more severe manifestations of hypokalemia that can occur if the condition is not promptly addressed. However, muscle weakness is often an early and noticeable sign that can alert healthcare providers to the need for intervention.
