The Correct Answer is ["A","B","C","D"]
- Client reports having three to four alcoholic beverages a couple times per week. Phenytoin metabolism is significantly affected by alcohol consumption. Chronic alcohol use increases phenytoin clearance, leading to subtherapeutic drug levels and seizure breakthrough. Conversely, acute alcohol intake inhibits phenytoin metabolism, increasing the risk of toxicity. The client should be counseled to avoid alcohol while on phenytoin therapy.
- Client takes diazepam as needed for anxiety. Diazepam is a CNS depressant that interacts with phenytoin, increasing sedation and the risk of respiratory depression. Both medications can cause drowsiness, dizziness, and impaired coordination, raising the risk of falls and injury. The provider should assess whether diazepam should be discontinued or adjusted when initiating phenytoin therapy.
- Last menstrual period was 3 months ago. Phenytoin is Pregnancy Category D, meaning it poses a significant teratogenic risk, including fetal hydantoin syndrome. The missed menstrual period suggests a possible pregnancy, which must be evaluated before starting phenytoin. A pregnancy test should be performed, and alternative antiseizure medications may need to be considered if pregnancy is confirmed.
- Client is a vegetarian and takes a multivitamin daily. Phenytoin interferes with the absorption of folic acid and vitamin D, both of which are crucial for bone health and red blood cell production. Vegetarians are already at higher risk for folate and vitamin B12 deficiency, making supplementation essential. However, multivitamins containing calcium, magnesium, or iron can decrease phenytoin absorption, reducing its effectiveness. The provider should review the multivitamin’s composition and adjust dosing schedules to prevent interactions.
- Temperature 36.4°C (97.6°F), oral. The client’s temperature is within normal range and does not indicate infection or systemic concerns that would affect phenytoin therapy.
- Heart rate 75/min, Respiratory rate 16/min, Blood pressure 100/74 mm Hg, Oxygen saturation 99% on room air.
All vital signs are stable and do not indicate hemodynamic instability, respiratory depression, or cardiovascular issues that would contraindicate phenytoin administration. - Skin color is consistent with genetic background. No rashes or lesions. The client has varicose veins. There are no signs of drug hypersensitivity reactions or dermatologic conditions that would require stopping phenytoin therapy.
- S1 S2 auscultated. No murmurs. All peripheral pulses 2+. Lung sounds clear bilaterally.
There are no cardiopulmonary concerns that would indicate contraindications to phenytoin. - Abdomen soft, nontender. Normoactive bowel sounds in all 4 quadrants. Last bowel movement was 3 days ago. Voids four to five times a day. Urine is clear, yellow, and odorless. Mild constipation is noted, but this is not a contraindication for phenytoin. The client should be encouraged to increase fiber and fluid intake to prevent worsening constipation, which can sometimes be a side effect of phenytoin.
- Alert and oriented to person, place, and time. Client has full range of motion and is able to maintain flexion against resistance in all four extremities. There are no neurological deficits requiring immediate intervention, and the client's baseline mental status is intact.

Related Questions
Correct Answer is A
Explanation
A. Baker's yeast. The hepatitis B vaccine is contraindicated in individuals with a severe allergy to baker’s yeast. This is because the vaccine is produced using Saccharomyces cerevisiae (baker’s yeast), which can trigger an allergic reaction in susceptible individuals. Symptoms of a yeast allergy may include rash, difficulty breathing, and anaphylaxis, requiring the vaccine to be withheld and an alternative plan considered.
B. Nuts. Nut allergies are not related to the hepatitis B vaccine, as it does not contain nut-derived ingredients. While nut allergies can be severe and cause anaphylaxis, they do not pose a specific risk in the administration of this vaccine. Therefore, the presence of a nut allergy alone does not require withholding the immunization.
C. Wheat. A wheat allergy is not a contraindication for the hepatitis B vaccine. Wheat allergies primarily cause reactions to gluten-containing foods or products but do not have any connection to the components used in the production of the vaccine. The vaccine can be safely administered to individuals with wheat allergies.
D. Egg yolk. While some vaccines, such as the influenza vaccine, may be derived from egg proteins, the hepatitis B vaccine is not produced using egg-based components. An allergy to egg yolk does not pose a risk for adverse reactions to this vaccine, so it should not be withheld in individuals with an egg allergy.
Correct Answer is D
Explanation
A. Add the medications to the enteral feeding bag. Medications should not be mixed with enteral feeding formula as this can alter drug absorption, cause tube clogging, or result in medication interactions. Each medication should be administered separately to ensure proper effectiveness.
B. Check for gastric residual 15 min after administering the medications. Gastric residual volume (GRV) should be checked before medication administration to assess delayed gastric emptying. Checking it after administration is unnecessary and may disrupt medication absorption without clinical benefit.
C. Keep the client's head elevated 15° while administering the medications. The head of the bed should be elevated at least 30–45 degrees, not 15 degrees, to reduce aspiration risk and promote medication passage. Insufficient elevation increases the likelihood of regurgitation and aspiration pneumonia.
D. Flush the tube with 30 ml of water between each medication. Flushing with 30 mL of water between medications prevents tube clogging and ensures each drug is properly delivered. It also minimizes drug interactions by preventing medications from mixing within the tube.
