The nurse is caring for a client who is receiving ondansetron IV. The nurse can be confident that treatment is effective when:

The client's heart rate falls to 65

The client's blood systolic blood pressure lowers to 118.

The client expresses hunger.

The client is no longer vomiting.

Answer and Explanation

The Correct Answer is D

A. The client's heart rate falls to 65: A heart rate of 65 bpm may be within normal range, but it is not a specific indicator of ondansetron’s effectiveness. Ondansetron is an antiemetic, and its success is measured by reduction in nausea and vomiting, not changes in heart rate.

B. The client's systolic blood pressure lowers to 118: While 118 mm Hg is a normal systolic reading, ondansetron does not have a direct therapeutic effect on blood pressure. Blood pressure changes are not a reliable measure of antiemetic treatment success.

C. The client expresses hunger: Expressing hunger could suggest relief from nausea, but it is a subjective and indirect sign. A client may still feel nausea or be reluctant to eat for other reasons, so hunger alone does not confirm effectiveness of ondansetron.

D. The client is no longer vomiting: Ondansetron works by blocking serotonin receptors in the chemoreceptor trigger zone and gastrointestinal tract. Its primary purpose is to prevent or stop vomiting, making cessation of vomiting the most direct and reliable sign of effectiveness.

Correct Answer is A

Explanation

A. "The different onsets and peaks of the two types provide better overall glucose control.": Regular insulin has a rapid onset and short duration, while NPH insulin has a slower onset and longer duration. When used together, they mimic the body's natural insulin release pattern, offering both immediate and sustained glucose control throughout the day.

B. "NPH prevents regular insulin from being broken down in the body, allowing the use of a lower dose.": NPH does not alter how regular insulin is metabolized. Each insulin type acts independently, and NPH does not preserve or enhance the activity of regular insulin.

C. "The combination negates the risk of adverse effects that would likely accompany a single, larger dose.": The primary reason for using two types is to align insulin activity with the body’s varying needs. Risk reduction from side effects is not the primary purpose.

D. "NPH stimulates the pancreas to produce more insulin, while regular insulin provides your body's short-term needs.": NPH insulin is synthetic and does not stimulate pancreatic insulin production. Clients with type 1 diabetes lack insulin production altogether, so both types must be provided exogenously.

A. decrease the amount of wastes excreted. B. improve and speed up the passage of the intestinal contents. C. increase the digestion of stomach contents. D. increase absorption of the contents of the intestines.

Correct Answer is B

Explanation

A. decrease the amount of wastes excreted: Laxatives do not reduce waste excretion; rather, they stimulate bowel movements to promote elimination. Their purpose is to relieve constipation by encouraging the evacuation of feces, not to decrease waste output.

B. improve and speed up the passage of the intestinal contents: Laxatives act by softening stool, stimulating peristalsis, or increasing water in the bowel to ease and hasten stool passage. This supports their use in treating constipation or preparing the bowel for procedures.

C. increase the digestion of stomach contents: Laxatives do not influence gastric digestion. Digestion involves enzymatic breakdown in the stomach and small intestine, while laxatives act primarily in the colon to facilitate stool movement and excretion.

D. increase absorption of the contents of the intestines: Many laxatives actually decrease absorption by accelerating transit through the intestines. The faster movement leaves less time for water and nutrients to be absorbed, often leading to looser stools.
