Question 1 of 5
A patient has been started on therapy of a continuous infusion of lidocaine after receiving a loading dose of the drug. The nurse will monitor the patient for which adverse effect?
Correct Answer: D
Rationale: Lidocaine is a local anesthetic drug that can lead to central nervous system (CNS) toxicity when given in excessive doses. Symptoms of lidocaine toxicity include drowsiness, confusion, visual disturbances, muscle twitching, seizures, and, in severe cases, cardiovascular collapse. Among the options provided, convulsions are the most concerning adverse effect associated with lidocaine toxicity. It is essential for the nurse to closely monitor the patient for any signs or symptoms of CNS toxicity and promptly report any concerning findings to the healthcare provider to prevent potentially serious complications.
Question 2 of 5
The patient is discharged home and returns to the emergency department 4 days later. The patient is admitted to the ICU with acute decompensated HF with dyspnea at rest. The nurse anticipates administration of which medication?
Correct Answer: D
Rationale: Nesiritide, also known as Natrecor, is a medication commonly used in the treatment of acute decompensated heart failure (ADHF) with dyspnea at rest. It is a recombinant form of B-type natriuretic peptide (BNP) which helps to improve cardiac function and alleviate symptoms of heart failure, such as dyspnea. Nesiritide works by promoting vasodilation and increasing diuresis, which can help reduce the workload on the heart and improve cardiac output. Therefore, in the case of a patient with acute decompensated heart failure and dyspnea at rest, the nurse would anticipate the administration of Nesiritide to help improve the patient's condition.
Question 3 of 5
The nurse is monitoring for adverse effects in a patient who is receiving an amiodarone
Correct Answer: A
Rationale: Adverse effects of amiodarone include QT prolongation and gray coloring of the skin on the face, arms, and neck.
Question 4 of 5
What is the therapeutic use of levothyroxine?
Correct Answer: C
Rationale: Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It is primarily used for the treatment of hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone. By providing exogenous levothyroxine, the medication helps to restore the normal hormonal balance in the body. This can alleviate symptoms such as fatigue, weight gain, cold intolerance, and other issues related to an underactive thyroid gland. Levothyroxine is not used for the suppression of seizure activity, decreased frequency of migraines, or treatment of ulcers.
Question 5 of 5
The primary beneficial action of epinephrine when performing root end surgery is which of the following?
Correct Answer: C
Rationale: Epinephrine primarily acts on beta1 adrenergic receptors in the alveolar mucosa during root end surgery. This results in vasoconstriction, which reduces bleeding in the surgical field by constricting blood vessels. With decreased bleeding, the surgical site becomes clearer, allowing for better visualization and manipulation during the procedure. Additionally, epinephrine may also prolong the duration of anesthesia by reducing systemic uptake of the local anesthetic solution, thus enhancing its effect locally.
