Question 1 of 5
What is the unlabeled use for Propranolol?
Correct Answer: A
Rationale: While Propranolol is commonly used to treat conditions such as hypertension and certain heart-related issues, it is also used off-label for the treatment of post-traumatic stress disorder (PTSD). Propranolol has shown efficacy in reducing the intensity of emotional memories and symptoms associated with PTSD by blocking the effects of stress hormones. It is believed to help alleviate symptoms such as anxiety and hyperarousal in individuals with PTSD. However, it is important to note that the off-label use of Propranolol for PTSD should only be done under the guidance and supervision of a healthcare professional.
Question 2 of 5
A 66-year-old man with a history of recurrent pulmonary infections and hypertension is managed with ethacrynic acid, which controls his hypertension well. He is often hospitalized and placed on gentamicin for his recurrent pulmonary infections. Which of the following adverse effects must the treating physician be keenly aware of?
Correct Answer: B
Rationale: Gentamicin, an aminoglycoside, risks ototoxicity-hearing loss , especially with repeated use. Ethacrynic acid, a loop diuretic, also has ototoxicity potential, compounding risk. Dizziness , nausea , vertigo , and vomiting (E) occur but are less specific. Monitoring hearing is critical in this scenario.
Question 3 of 5
What is the expected outcome for Valproate?
Correct Answer: D
Rationale: Valproate is an anticonvulsant medication commonly used to treat seizures, epilepsy, and bipolar disorder. It works by increasing levels of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) in the brain and also affects other neurotransmitters. Therefore, the expected outcome of taking Valproate is to decrease seizure activity by stabilizing abnormal electrical activity in the brain.
Question 4 of 5
Lorraine who is on chemotherapy has a history of cardiac disease. The client is at risk for cardiac complications because:
Correct Answer: B
Rationale: Chemotherapy can cause anemia, which reduces the oxygen-carrying capacity of the blood due to decreased red blood cells or hemoglobin. For a patient with a history of cardiac disease, this is particularly concerning because the heart must work harder to deliver oxygen to tissues, potentially exacerbating cardiac conditions. Reduced white blood cells increase infection risk, but this does not directly affect cardiac function. Sodium levels and hematocrit are not the primary concerns in this context. Therefore, reduced oxygen-carrying capacity is the correct answer.
Question 5 of 5
The patient has been prescribed oxymetazoline (Afrin). What medication information should the nurse provide?
Correct Answer: D
Rationale: Oxymetazoline acts fast; adherence prevents rebound . Days is wrong. D ensures safe use, making it key.
