Question 1 of 5
A client is prescribed levothyroxine (Synthroid) for hypothyroidism. When is the best time for the nurse to instruct the client to take this medication?
Correct Answer: C
Rationale: Levothyroxine replaces thyroid hormone, requiring optimal absorption for efficacy. Taking it on an empty stomach in the morning avoids interference from food (e.g., calcium, iron), which reduces uptake, ensuring consistent T4 levels. With breakfast or dinner , absorption drops due to dietary interactions, risking subtherapeutic effects. At bedtime is viable but less ideal if food was recent, and morning aligns with circadian thyroid function. This timing leverages levothyroxine's pharmacokinetics'long half-life but sensitivity to gut contents'maximizing bioavailability. Instructing this prevents treatment failure in hypothyroidism, where precise dosing matters, making C the best time for administration and client education.
Question 2 of 5
A student nurse was asked by the nurse instructor to explain the procedure for the administration of erythromycin ointment to the eyes of the newborn. Which of the following statements made by the student indicates a need for further research?
Correct Answer: D
Rationale: After administering erythromycin ointment to the eyes of the newborn, there is no need to flush the eyes. The ointment is meant to be left in the eyes to provide protection against eye infections that can be acquired during birth. Flushing the eyes after instilling the ointment may reduce its effectiveness and is not part of the standard procedure. The ointment should be applied directly to the conjunctival sacs without rinsing or flushing the eyes.
Question 3 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 can be given in infusions with other medications, such as saline or dextrose solutions, to manage acute conditions like acute myocardial infarction. Combining nitroglycerin with other medications in an infusion is a common practice to treat patients in critical conditions and optimize therapy. This allows healthcare providers to administer multiple medications simultaneously through the same IV line, ensuring prompt and effective treatment.
Question 4 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: Potassium supplements are contraindicated in patients with renal disease because impaired kidney function can lead to the inability to adequately excrete potassium. This can result in potentially dangerous hyperkalemia (high potassium levels) in the bloodstream, which can cause serious cardiac dysrhythmias. Therefore, patients with renal disease should be cautious when taking potassium supplements or may need to avoid them altogether to prevent complications.
Question 5 of 5
The nurse is reviewing the orders for a patient and notes a new order for an angiotensin-
Correct Answer: D
Rationale: Angiotensin-converting enzyme (ACE) inhibitors, a type of angiotensin inhibitor, may have a serious interaction with nonsteroidal anti-inflammatory drugs (NSAIDs). This interaction can potentially reduce the effectiveness of the ACE inhibitor in lowering blood pressure and may cause kidney damage in susceptible individuals. Therefore, it is crucial for the nurse to be aware of this potential drug interaction and to monitor the patient for any signs of adverse effects when these two drug classes are used together.
