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.

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.

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.

Correct Answer: C

Rationale: It is important to remove the transdermal Nitroglycerine patch for 10-12 hours every night to prevent the development of tolerance. Tolerance can occur when the body becomes less responsive to the medication over time, reducing its effectiveness. By allowing a break in Nitroglycerine administration overnight, tolerance development can be minimized, ensuring the medication remains effective for the patient when needed. This nursing intervention helps to maintain the efficacy of Nitroglycerine in managing anginal attacks for the patient.

Correct Answer: C

Rationale: Albuterol is a medication commonly used as a bronchodilator. It works by relaxing the muscles in the airways and increasing airflow to the lungs. This medication is commonly used to treat conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory issues where bronchodilation is needed to ease breathing difficulties. Warfarin is an anticoagulant used to prevent blood clots, Lovastatin is a statin medication used to lower cholesterol levels, and Valproate is an anticonvulsant used to treat seizures.
