Question 1 of 5
When applying transdermal nitroglycerin patches, which instruction by the nurse is correct?
Correct Answer: A
Rationale: The correct instruction by the nurse when applying transdermal nitroglycerin patches is to "Rotate application sites with each dose." This is important to prevent skin irritation and tolerance to the medication. It is recommended to apply the patch to a different, clean, hairless area of skin for each dose to ensure proper absorption and effectiveness of the medication. Additionally, rotating application sites helps reduce the risk of skin reactions such as redness, itching, or rash.
Question 2 of 5
The nurse is giving intravenous nitroglycerin to a patient who has just been admitted because of an acute myocardial infarction. Which statement is true regarding the administration of the intravenous form of this medication?
Correct Answer: D
Rationale: Intravenous nitroglycerin is commonly administered in infusions along with other medications, such as heparin and morphine, to manage acute myocardial infarction. By giving it in infusions, healthcare providers can control the dosage and titrate it to the patient's response while also minimizing the risk of sudden drops in blood pressure. Additionally, administering nitroglycerin in infusions allows for precise and continuous delivery of the medication to achieve the desired therapeutic effect.
Question 3 of 5
When reviewing the health history of a patient, the nurse will note that a potential contraindication to potassium supplements exists if the patient has which problem?
Correct Answer: C
Rationale: Patients with renal disease may have difficulty excreting potassium properly. If a patient with renal disease takes potassium supplements, it can lead to hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can be dangerous and may result in cardiac dysrhythmias and other serious complications. Therefore, patients with renal disease should avoid potassium supplements unless directed otherwise by their healthcare provider.
Question 4 of 5
Which is not one of the rights of medication administration?
Correct Answer: C
Rationale: The five rights of medication administration are: the right patient, the right drug, the right dose, the right route, and the right time. These are essential principles to ensure safe and effective medication administration. The attitude of the healthcare provider is important for delivering care, but it is not included as one of the fundamental rights of medication administration. It is important for healthcare providers to approach medication administration with professionalism, compassion, and attentiveness, but it is not considered one of the primary rights in the context of medication administration protocols.
Question 5 of 5
A patient is taking the urinary antiseptic methenamine for a urinary tract infection (UTI). The nurse understands that this drug should not be given concurrently with which other drug to avoid crystalluria?
Correct Answer: D
Rationale: Methenamine is a urinary antiseptic that works by converting to formaldehyde in the urine, creating an inhospitable environment for bacterial growth. Trimethoprim-sulfamethoxazole is a sulfonamide antibiotic that can potentiate the formation of crystals in the urine (crystalluria). Therefore, giving methenamine and trimethoprim-sulfamethoxazole concurrently can increase the risk of crystalluria. It is important to avoid combining these two medications to prevent potential adverse effects on the urinary tract.
