Which patient is most at risk for postoperative na

Question 1 of 5

Which patient is most at risk for postoperative nausea and vomiting (PONV)?

A. The patient with a history of motion sickness B. The patient with a nasogastric tube C. The patient who recently experienced a weight loss of 50 pounds D. The patient who had minimally invasive surgery (MIS)

Correct Answer: A

Rationale: The patient with motion sickness is most at risk for PONV due to vestibular sensitivity. NG tubes , weight loss , and MIS have less direct impact. The rationale ties to physiology: motion sickness history predicts opioid or anesthetic-induced nausea, a PONV trigger. Nursing anticipates antiemetics, targeting this risk, distinct from procedural or nutritional factors.

Question 2 of 5

Which of the following statements is the correct way for patients to splint incisions when they cough?

A. Have the patient deep breathe while they provide medium pressure over the incision B. Hold both hands on top of each other strongly exerting pressure over the incision C. Put the palms of the fingers together and interlace the fingers snugly and place hands across incision D. Hold one hand gently directly over the incision and breathe deeply before coughing

Correct Answer: D

Rationale: The correct splinting method is holding one hand gently over the incision and breathing deeply before coughing . Medium pressure lacks specificity; strong pressure risks damage; interlacing is impractical. The rationale explains technique: gentle support stabilizes the incision, reducing dehiscence risk during coughing's strain, while deep breathing aids lung expansion. Nursing teaches this, ensuring comfort and safety, distinct from excessive force or awkward positioning, promoting healing.

Question 5 of 5

The nurse is preparing a patient for surgery prior to her hysterectomy without oophorectomy. The nurse is witnessing the patient's signature on a consent form. Which comment by the patient would best indicate informed consent?

A. I know I'll be fine because the physician said he has done this procedure hundreds of times. B. I know I'll have pain after the surgery but they'll do their best to keep it to a minimum. C. The physician is going to remove my uterus and told me about the risk of bleeding. D. Because the physician isn't taking my ovaries, I'll still be able to have children.

Correct Answer: C

Rationale: Informed consent requires the patient to understand the procedure, risks, benefits, and alternatives, as explained by the surgeon. Choice C shows the patient knows the uterus will be removed and acknowledges bleeding risk, indicating comprehension. Choice A relies on the surgeon's experience, not procedure details; B addresses pain but not specifics; D is factually incorrect hysterectomy prevents pregnancy despite retaining ovaries. The nurse ensures clarity, notifying the physician if more explanation is needed, per legal and ethical standards.
