The nurse is working with a graduate nurse to prepare an intravenous dose of potassium. Which statement by the graduate nurse reflects a need for further teaching?

Correct Answer: D

Rationale: The statement "The intravenous potassium dose will be given undiluted" reflects a need for further teaching. Potassium should always be diluted before administration to reduce the risk of causing irritation or damage to the veins. Administration of concentrated potassium solution can lead to serious complications, including local tissue damage, phlebitis, and even cardiac arrest. It is essential to dilute intravenous potassium solutions to ensure safe administration and minimize the risk of adverse effects.

Correct Answer: D

Rationale: Glargine insulin, commonly known by the brand name Lantus, is a long-acting type of insulin. It is designed to provide a steady level of insulin over an extended period, usually lasting up to 24 hours. This type of insulin is often used as a basal insulin to help control blood sugar levels between meals and overnight. In contrast, Lispro (Humalog) is a rapid-acting insulin used to manage blood sugar spikes after meals, NPH (Humulin N) is an intermediate-acting insulin, and Regular insulin (Humulin R) is a short-acting insulin.

Correct Answer: C

Rationale: Albuterol is a bronchodilator medication commonly used to treat bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease (COPD). Albuterol can be given in various forms, including extended-release tablets for oral use, inhalation solutions for nebulization, and oral syrups. However, albuterol is not typically administered intravenously because it can cause severe cardiovascular side effects, such as tachycardia and arrhythmias, when given directly into the bloodstream. For this reason, intravenous administration of albuterol is contraindicated in most cases and is not a common route of administration for this medication.

Correct Answer: D

Rationale: Nitroglycerin is a medication commonly used in the treatment of angina pectoris (chest pain) and heart failure. Its primary action is to dilate the coronary arteries, which are the blood vessels that supply the heart muscle with oxygen and nutrients. By dilating these arteries, nitroglycerin helps to increase blood flow to the heart and reduce the workload on the heart muscle, thereby relieving chest pain and improving overall heart function. This vasodilatory effect of nitroglycerin also helps in reducing blood pressure and increasing oxygen supply to the heart. Therefore, the correct action of nitroglycerin is to dilate the coronary arteries.

Correct Answer: D

Rationale: Ondansetron is typically administered orally, commonly in the form of tablets, orally disintegrating tablets, or liquid solution. The medication is absorbed through the gastrointestinal tract when taken orally, making it an effective route of administration for managing nausea and vomiting. SubQ (subcutaneous), sublingual, and buccal routes are not typical routes of administration for ondansetron.
