Question 1 of 9
In infants and children, the side effects of first-generation over-the-counter (OTC) antihistamines, such as diphenhydramine (Benadryl) and hydroxyzine (Atarax) include:
Correct Answer: C
Rationale: First-generation antihistamines can cause paradoxical central nervous system (CNS) stimulation in children, leading to hyperactivity, agitation, and insomnia. This is contrary to their sedative effects in adults. Reye's syndrome is associated with aspirin, not antihistamines. Cholinergic effects and gastrointestinal symptoms are less common in children.
Question 2 of 9
What patient could potentially take the drug Senna?
Correct Answer: B
Rationale: Senna is a stimulant laxative commonly used to treat constipation. It works by irritating the lining of the intestines, thereby promoting bowel movements. Patients who have not passed stool in several days may benefit from taking Senna to help relieve constipation and promote regular bowel movements. Patients with conditions such as eating disorders, anal fissures, or hemorrhoids may also benefit from stool softeners or other laxatives, but Senna specifically targets constipation due to its stimulant properties. It is essential to consult with a healthcare provider before starting any laxative therapy to determine the appropriate treatment plan for each individual.
Question 3 of 9
A patient has received an IV dose of adenosine, and almost immediately the heart monitor shows
Correct Answer: D
Rationale: Adenosine is a medication commonly used to treat certain types of irregular heartbeats, such as supraventricular tachycardia. One of the common side effects of adenosine administration is transient asystole or a brief pause in the electrical activity of the heart. This can cause the heart to stop beating momentarily, leading to a drop in blood pressure and a feeling of lightheadedness in the patient. Therefore, in this scenario where the heart monitor shows an immediate abnormality after adenosine administration, the nurse should prepare to administer cardiopulmonary resuscitation and be ready to intervene if the patient's heart rhythm deteriorates further. It is crucial to be proactive and prepared to respond quickly to any adverse effects of the medication to prevent potential harm to the patient. Regular monitoring should also continue to assess the patient's condition and response to treatment.
Question 4 of 9
In infants and children, the side effects of first-generation over-the-counter (OTC) antihistamines, such as diphenhydramine (Benadryl) and hydroxyzine (Atarax) include:
Correct Answer: C
Rationale: First-generation antihistamines can cause paradoxical central nervous system (CNS) stimulation in children, leading to hyperactivity, agitation, and insomnia. This is contrary to their sedative effects in adults. Reye's syndrome is associated with aspirin, not antihistamines. Cholinergic effects and gastrointestinal symptoms are less common in children.
Question 5 of 9
A patient is taking infliximab and asks the nurse what side effects/adverse reactions to expect from this drug. The nurse lists which side effects? (Select all that apply.)
Correct Answer: D
Rationale: Infliximab is a biologic medication used to treat autoimmune conditions like rheumatoid arthritis and Crohn's disease. Common side effects include fatigue and headache, which are generally mild but can affect the patient's quality of life. Chest pain is a less common but serious side effect that may indicate cardiovascular complications or infusion reactions. Nausea is not typically associated with infliximab. Nurses should educate patients about these potential side effects and advise them to report any severe or persistent symptoms, such as chest pain, immediately.
Question 6 of 9
When starting a patient on antidysrhythmic therapy, the nurse will remember that which problem is a potential adverse effect of any antidysrhythmic drug?
Correct Answer: D
Rationale: While it may seem counterintuitive that starting a patient on antidysrhythmic therapy could potentially cause dysrhythmias, it is important to remember that antidysrhythmic drugs can have proarrhythmic effects. Proarrhythmia refers to the development of new or more severe dysrhythmias as a result of the medication intended to treat dysrhythmias. This can occur due to various mechanisms, such as altering the electrical conduction system of the heart or disrupting the normal rhythm. Therefore, dysrhythmias are a potential adverse effect that the nurse should monitor for when initiating antidysrhythmic therapy in a patient. It is crucial for the healthcare team to closely monitor the patient's cardiac rhythm and adjust the medication regimen as needed to minimize the risk of proarrhythmia.
Question 7 of 9
Drugs that produce stupor
Correct Answer: A
Rationale: Sedatives are a type of drug that depresses the central nervous system and can induce a state of calmness and relaxation. In higher doses, sedatives can lead to stupor, which is a state of near-unconsciousness or insensibility. Stupor is often characterized by a marked decrease in alertness and responsiveness. Examples of sedatives include benzodiazepines, such as Valium and Xanax, as well as non-benzodiazepine sedatives like Ambien and Lunesta.
Question 8 of 9
Liquid preparation of vegetable drugs prepared by percolation and contains alcohol
Correct Answer: B
Rationale: In this context, a liquid preparation of vegetable drugs prepared by percolation and containing alcohol is known as a fluid extract. Fluid extracts are concentrated herbal extracts that are typically made by percolating a solvent, such as alcohol, through the plant material to extract its active constituents. This process results in a liquid extract that contains the medicinal properties of the plant. Fluid extracts are commonly used in herbal medicine due to their potency and ability to preserve the therapeutic compounds of the plant.
Question 9 of 9
The nurse is caring for a patient with colorectal cancer who is to receive fluorouracil. Which symptom will be most important for the nurse to report to the health care provider?
Correct Answer: C
Rationale: Fluorouracil, an antimetabolite chemotherapy drug, can cause myelosuppression, leading to a decrease in platelets (thrombocytopenia). Bleeding gums is a sign of low platelet counts and potential bleeding risk, which can be life-threatening if not addressed promptly. Nausea, decreased appetite, and constipation are common side effects of chemotherapy but are not as urgent as bleeding gums, which indicates a potential hematologic emergency. The nurse should report this symptom immediately to the healthcare provider for further evaluation and intervention, such as platelet transfusion or dose adjustment.
