A nurse in a clinic receives a telephone call from a client who has tuberculosis and was prescribed rifampin 3 days ago. The client reports, "My saliva and tears are red. What should I do?" Which of the following responses by the nurse is appropriate?

"This is an expected adverse effect of the medication.”

"Stop taking the medication. You are having an allergic reaction.

"This condition will only last a couple of days."

"Taking the medication with red meat will cause this adverse effect."

Answer and Explanation

The Correct Answer is A

A. "This is an expected adverse effect of the medication." Rifampin commonly causes red-orange discoloration of bodily fluids, including saliva, tears, urine, and sweat. This occurs due to the drug's excretion and is harmless. It does not indicate internal bleeding or organ dysfunction. Clients should be educated about this side effect in advance to prevent alarm and unnecessary discontinuation of the medication, as adherence to tuberculosis treatment is crucial.

B. "Stop taking the medication. You are having an allergic reaction." The red discoloration caused by rifampin is a known side effect, not an allergic reaction. A true allergic response would include symptoms such as rash, itching, swelling, or difficulty breathing. Stopping rifampin without medical advice could disrupt tuberculosis treatment, leading to drug resistance or treatment failure, making this an inappropriate recommendation.

C. "This condition will only last a couple of days." The discoloration of bodily fluids persists throughout the duration of rifampin therapy. Tuberculosis treatment can last several months, so the client should expect this effect to continue as long as they are taking the medication. Providing incorrect information may cause the client to worry unnecessarily when the discoloration does not resolve quickly.

D. "Taking the medication with red meat will cause this adverse effect." The discoloration is due to rifampin’s chemical properties and metabolism, not dietary intake. Red-colored foods, such as red meat or berries, do not influence this effect. Providing inaccurate dietary information may lead to unnecessary dietary restrictions, which are not needed for managing this side effect.

Correct Answer is B

Explanation

A. Tingling sensation. A mild tingling or paresthesia is a common side effect of sumatriptan due to its vasoconstrictive action. While it should be monitored, it is not typically harmful and does not require immediate medical intervention.

B. Hypertension. Sumatriptan works by constricting blood vessels to relieve migraine symptoms, but it can also cause a dangerous increase in blood pressure. Severe hypertension can lead to complications such as stroke or myocardial infarction. This is the priority finding that requires immediate reporting to prevent life-threatening cardiovascular events.

C. Dizziness. Dizziness can occur due to sumatriptan’s vasoconstrictive properties or from the migraine itself. While it can be uncomfortable, it is not an immediate threat to the client’s safety unless it is severe or associated with other neurological symptoms.

D. Flushing. Facial flushing is a known side effect of sumatriptan and is generally harmless. It occurs due to transient vasodilation in the skin and does not indicate a serious adverse reaction. Monitoring is appropriate, but it does not require urgent intervention.

A. Client is a vegetarian and takes a multivitamin daily B. Client reports having three to four alcoholic beverages a couple times per week C. Last menstrual period was 3 months ago D. Client takes diazepam as needed for anxiety E. Temperature 36.4° C (97.6° F) F. Respiratory rate 16/min G. Blood pressure 100/74mm Hg H. Oxygen saturation 99% on room air I. S1 S2 auscultated J. Client has full range of motion and is able to maintain flexion against resistance in all four extremities K. Last bowel movement was 3 days ago.

Correct Answer is ["A","B","C","D"]

Explanation

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.
