A nurse is monitoring a client who received a local injection of lidocaine. Which of the following responses should the nurse expect?

Ventricular fibrillation

Tachycardia

Client reports of increased pain in the area

Client reports of numbness in the area

Answer and Explanation

The Correct Answer is D

A. “Ventricular fibrillation”: Ventricular fibrillation is a serious cardiac rhythm disturbance that can be life-threatening. It is not a typical response to a local injection of lidocaine.

B. “Tachycardia”: Tachycardia, or a rapid heart rate, is not a typical response to a local injection of lidocaine. Lidocaine is a local anesthetic and does not typically affect heart rate.

C. “Client reports of increased pain in the area”: Lidocaine is a local anesthetic used to numb a specific area of the body. It should not cause increased pain in the area. If the client reports increased pain, it could indicate a problem such as an allergic reaction or infection.

D. “Client reports of numbness in the area”: This is the expected response to a local injection of lidocaine. Lidocaine works by blocking nerve signals in the body, which results in numbness or loss of feeling in the area where it was injected.

Correct Answer is B

Explanation

A. “Increased level of consciousness”: While theophylline can have some stimulant effects, an increased level of consciousness is not the primary therapeutic goal of this medication. Theophylline is used to treat respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD), so its effectiveness is measured by improvement in respiratory symptoms.

B. “Decreased wheezing”: This is the correct answer. Theophylline is a bronchodilator, meaning it helps to open up the airways in the lungs. This can lead to a decrease in symptoms such as wheezing. Therefore, decreased wheezing is an indication that the medication is effective.

C. “Increased blood pressure”: Theophylline can potentially cause an increase in heart rate, which could lead to an increase in blood pressure. However, this is more likely to be a side effect of the medication rather than an indication of its effectiveness.

D. “Decreased urine output”: Theophylline does not typically affect urine output. Therefore, a decrease in urine output would not be an indication that the medication is effective.

A. Hydroxyzine B. Clozapine C. Linezolid D. Nortriptyline

Correct Answer is C

Explanation

A. Hydroxyzine: Hydroxyzine is an antihistamine medication commonly used to treat anxiety and allergic reactions. While it may have interactions with other medications, it is not specifically contraindicated with mirtazapine. However, caution should be exercised when combining medications with sedative effects.

B. Clozapine: Clozapine is an antipsychotic medication primarily used to treat schizophrenia in cases where other medications have not been effective. While it may have interactions with other drugs, it is not specifically contraindicated with mirtazapine. However, caution should be exercised when combining multiple psychotropic medications.

C. Linezolid: Linezolid is an antibiotic medication used to treat certain bacterial infections, including those caused by drug-resistant organisms. It is contraindicated with mirtazapine due to the risk of serotonin syndrome, a potentially life-threatening condition that can occur when serotonin levels in the brain become too high. Concurrent use of linezolid and mirtazapine can lead to serotonin syndrome due to their effects on serotonin levels.

D. Nortriptyline: Nortriptyline is a tricyclic antidepressant medication used to treat depression and various other conditions. While it may interact with other drugs, it is not specifically contraindicated with mirtazapine. However, caution should be exercised when combining multiple antidepressant medications due to the risk of serotonin syndrome.
