Antiemetics and Antinausea Drugs

A patient on warfarin (Coumadin) tells the nurse they take ginger daily for nausea. Why is this concerning?

Match the following enteral nutrition formulations with their primary characteristic:

Which of these conditions indicates a potential need for feeding tubes and enteral nutrition?

A patient receiving enteral nutrition exhibits nausea, weakness, sweating and palpitations shortly after feeding. Which complication is most likely occurring?

A patient receiving enteral feeding exhibits signs of lactose intolerance. Which action is most appropriate?

List three potential components of a TPN formulation that address individual patient nutritional needs.

Peripheral TPN is typically used for short-term nutritional support, generally less than ______ weeks.

Match the following TPN administration routes with their typical duration of use:

Which of the following is a potential risk specifically associated with central TPN, but not typically with peripheral TPN?

If TPN is discontinued abruptly, there is a risk of rebound hyperglycemia due to the pancreas's continued high insulin production.

A nurse is monitoring a patient receiving TPN and notices symptoms such as headache, dehydration, and weakness. These findings are most indicative of which complication?

Which of the following antiemetic drug classes primarily targets the inner ear labyrinth to prevent transmission of nauseating stimuli to the chemoreceptor trigger zone (CTZ)?

Administering hydroxyzine intravenously is a safe and preferred method due to its rapid effect on reducing nausea.

What is the primary mechanism of action of prokinetic drugs in treating nausea and vomiting related to gastroesophageal reflux disease?

Serotonin blockers such as ondansetron are particularly effective in managing nausea and vomiting associated with ________ and postoperative conditions.

Match the following antiemetic drug types with their primary mechanism of action:

A patient is prescribed ondansetron intravenously. What is the recommended maximum dose and administration time to minimize the risk of dysrhythmia?

Tetrahydrocannabinoids (THC) relieve nausea and vomiting by directly activating dopamine receptors in the vomiting center.

When educating a patient about taking anti-nausea medications, which instruction is most important to include?

Why are antiemetics often administered 30 to 60 minutes before chemotherapy?

Taking antiemetics with alcohol may cause severe central nervous system stimulation.

What specific instruction should nurses provide to patients taking antiemetics to prevent hypotensive effects?

A patient taking ginger regularly should be monitored, especially if they are also taking ______ due to potential interactions.

Which type of enteral formula is most appropriate for patients with fully functional GI tracts and few specialized nutrient requirements?

Which of the following antiemetic drug classes works by inhibiting acetylcholine, thus preventing cholinergic stimulation in the vestibular and reticular areas?

Modular enteral formulas provide a complete nutritional profile in a single formulation.

A patient receiving enteral nutrition suddenly develops nausea, weakness, sweating, and palpitations. Which adverse effect is the most likely cause?

Prokinetic drugs work by blocking dopamine receptors in the chemoreceptor trigger zone (CTZ) and stimulating peristalsis in the GI tract.

What is a significant risk associated with the intravenous (IV) administration of promethazine?

Match the following enteral nutrition types with their appropriate usage:

Serotonin blockers, such as ondansetron, are primarily used to treat nausea and vomiting associated with ______ and postoperative states.

Match the antiemetic drug with its primary mechanism of action:

A patient with glaucoma should avoid which type of anti-nausea medication?

Which of the following statements is correct regarding the use of ondansetron (Zofran®)?

Ginger may decrease the absorption of oral medications.

A patient receiving enteral feeding exhibits signs of lactose intolerance. What is the most appropriate initial nursing action?

Parenteral nutrition requires the normal functioning of the gastrointestinal system for nutrient absorption.

What is a primary risk associated with administering peripheral TPN due to the lower concentration of dextrose?

Central TPN is preferred over peripheral TPN when nutritional support is needed for a period longer than ______ days.

Which of the following is NOT a typical indication for peripheral parenteral nutrition?

Match each potential complication with its corresponding sign or symptom in a patient receiving TPN:

A patient's TPN is abruptly discontinued due to unforeseen circumstances. Which intervention is most important to prevent rebound hypoglycemia?

Increased thirst is a sign of hypoglycemia in patients receiving TPN.
