A client with peptic ulcer disease is prescribed sucralfate. What is the mechanism of action of this medication?
- A. Neutralizes stomach acid
- B. Decreases gastric acid secretion
- C. Covers the ulcer site and protects it from acid
- D. Improves gastric motility
Correct Answer: C
Rationale: The correct answer is C: Covers the ulcer site and protects it from acid. Sucralfate works by forming a protective barrier over ulcers, shielding them from stomach acid and promoting healing. Choice A, neutralizing stomach acid, is incorrect as sucralfate does not neutralize acid but acts as a physical barrier. Choice B, decreasing gastric acid secretion, is not the mechanism of action of sucralfate. Choice D, improving gastric motility, is unrelated to sucralfate's action on peptic ulcers.

A client who is receiving general anesthesia begins to demonstrate symptoms of malignant hyperthermia. Which intervention should the perioperative nurse prepare to implement first?
- A. Ensure patency of an indwelling catheter and measure hourly intake and output.
- B. Prepare for cessation of the anesthesia and the surgical procedure.
- C. Obtain specimens of ABGs and serum electrolytes.
- D. Initiate cooling measures using iced normal saline by nasogastric lavage.
Correct Answer: B
Rationale: The correct answer is B: Prepare for cessation of the anesthesia and the surgical procedure. Malignant hyperthermia is a severe reaction to certain medications used during general anesthesia. The immediate intervention to manage malignant hyperthermia is to stop the triggering agents, which include anesthesia and surgery. Ensuring patency of an indwelling catheter and measuring intake and output, obtaining specimens of ABGs and serum electrolytes, and initiating cooling measures are important interventions but should follow the immediate action of stopping the anesthesia and surgery to address the life-threatening condition of malignant hyperthermia.
Which instruction should be included in the discharge teaching plan for a client who has had a cataract extraction today?
- A. Use a metal eye shield on the operative eye during the day.
- B. Administer eye ointment after applying eye drops.
- C. Light housekeeping is safe to do, but avoid heavy lifting.
- D. Refrain from sexual activities until follow-up appointment.
Correct Answer: C
Rationale: The correct instruction to include in the discharge teaching plan for a client who has had a cataract extraction is that light housekeeping is safe to do, but heavy lifting should be avoided to prevent increased intraocular pressure. Choice A is incorrect as the eye shield is usually worn at night to protect the eye. Choice B is incorrect as eye ointment is usually applied after eye drops to avoid washing away the ointment. Choice D is incorrect as sexual activities should be avoided until the follow-up appointment to prevent complications.
Which is a long-term complication of cleft lip and palate?
- A. Cognitive impairment
- B. Altered growth and development
- C. Faulty dentition
- D. Physical abilities
Correct Answer: C
Rationale: The correct answer is C, 'Faulty dentition.' The older child with cleft lip and palate may experience psychological difficulties due to the cosmetic appearance of the defect, issues with impaired speech, and faulty dentition. This can lead to problems with dental alignment, crowding, missing or malformed teeth, and other dental issues. Choices A, B, and D are incorrect as cognitive impairment, altered growth and development, and physical abilities are not typically considered long-term complications of cleft lip and palate.
The nurse is teaching a client how to collect a sputum specimen. Which steps should the nurse instruct the client to follow when collecting sputum?
- A. Breathe deeply, followed by swallowing.
- B. Breathe deeply, followed by spitting into a cup.
- C. Breathe deeply, followed by coughing up the sputum.
- D. Breathe deeply, followed by clearing the throat.
Correct Answer: C
Rationale: The correct answer is to instruct the client to breathe deeply followed by coughing up the sputum. This method ensures that the specimen is collected from the lower respiratory tract and is not contaminated by saliva. Choice A (swallowing) does not result in sputum collection, while choice B (spitting into a cup) may lead to saliva contamination. Choice D (clearing the throat) is not an effective way to collect sputum as it may involve getting rid of saliva, not sputum.
A client with urolithiasis is preparing for discharge after lithotripsy. Which intervention should the nurse include in the client's postoperative discharge instructions?
- A. Report when hematuria becomes pink-tinged
- B. Use incentive spirometer
- C. Restrict physical activities
- D. Monitor urinary stream for a decrease in output
Correct Answer: D
Rationale: After lithotripsy, monitoring the urinary stream for a decrease in output is essential to identify any potential complications such as urinary retention or obstruction. Reporting pink-tinged hematuria is important, but monitoring the urinary stream for a decrease in output takes precedence as it directly assesses renal function and potential complications. Using an incentive spirometer is not directly related to post-lithotripsy care. Restricting physical activities may be necessary initially but is not the priority compared to monitoring urinary output.
