A nurse is teaching a client who has a new prescription for cimetidine to treat peptic ulcer disease. Which of the following statements by the client indicates an understanding of the teaching? (Select all that apply)
I will take this medication when I need it for pain.
I should expect my stools to turn black.
I can take this medication with or without food.
I will eat five small meals each day.
I will take this medication with an antacid.
Correct Answer : C,D
Choice A reason: Cimetidine, an H2 receptor antagonist, reduces gastric acid secretion and is taken regularly to prevent ulcer recurrence, not as needed for pain. PRN dosing is ineffective for maintaining consistent acid suppression, which is necessary for ulcer healing and preventing acid-related damage to the gastric mucosa.
Choice B reason: Black stools typically indicate gastrointestinal bleeding, often due to ulcer perforation, not a normal effect of cimetidine. Cimetidine reduces acid to promote ulcer healing, preventing bleeding. Black stools require urgent evaluation, as they suggest melena, potentially from hemoglobin oxidation in the digestive tract.
Choice C reason: Cimetidine’s absorption is minimally affected by food, allowing administration with or without meals. This flexibility ensures consistent acid suppression, as it blocks histamine receptors on parietal cells, reducing hydrochloric acid production, which promotes ulcer healing and symptom relief regardless of meal timing.
Choice D reason: Eating five small meals reduces gastric acid demand and prevents stomach distension, which can exacerbate ulcers. This dietary approach minimizes acid secretion spikes, allowing cimetidine to maintain a stable gastric pH, promoting mucosal healing and reducing irritation from excessive acid exposure.
Choice E reason: Taking cimetidine with antacids can reduce its absorption, as antacids alter gastric pH, potentially decreasing bioavailability. Cimetidine’s acid suppression is sufficient alone, and concurrent antacid use may interfere with its pharmacokinetics, reducing efficacy in treating peptic ulcer disease.

Correct Answer is A
Explanation
Choice A reason: In Kohlberg’s social contract stage (Stage 5), individuals recognize that rules are social agreements that can be challenged if they infringe on individual rights or societal welfare. This post-conventional stage involves critical thinking about justice, balancing personal ethics with societal laws, and advocating for change when rules violate fundamental human rights or fairness.
Choice B reason: The good boy-nice girl stage (Stage 3) focuses on conforming to social expectations to gain approval. Individuals adhere to rules to maintain relationships and be seen as “good,” not to challenge rules. This conventional stage prioritizes social harmony over questioning unjust laws, making it incorrect for this scenario.
Choice C reason: The punishment and obedience stage (Stage 1) involves adhering to rules to avoid punishment, not challenging them. Individuals at this pre-conventional stage follow rules out of fear of consequences, lacking the moral reasoning to question rules that violate rights, making this an incorrect choice for Kohlberg’s theory.
Choice D reason: The law and order stage (Stage 4) emphasizes upholding societal rules and authority to maintain order. Individuals adhere to laws as a duty, without questioning their fairness or impact on rights. This conventional stage does not involve challenging unjust rules, making it incorrect for the described moral development stage.
Correct Answer is A
Explanation
Choice A reason: Checking the airway is the priority in post-anesthesia care, as anesthesia can cause respiratory depression or obstruction due to reduced pharyngeal muscle tone. Ensuring airway patency prevents hypoxia, maintaining oxygen delivery to vital organs, critical for patient safety and stabilization post-surgery.
Choice B reason: Level of consciousness is assessed after ensuring airway and breathing, as anesthesia (e.g., propofol) depresses the central nervous system. While important for neurological status, it is secondary to airway patency, as hypoxia from an obstructed airway poses an immediate life-threatening risk in the post-anesthesia period.
Choice C reason: Blood pressure monitoring is crucial to assess hemodynamic stability post-anesthesia, as hypotension may result from anesthetic agents or blood loss. However, airway obstruction causes hypoxia faster than cardiovascular instability, making airway assessment the first priority to ensure oxygenation before addressing circulatory parameters.
Choice D reason: Pain assessment is important for patient comfort and recovery but is not the first priority. Uncontrolled pain may increase sympathetic activity, affecting heart rate, but airway compromise causes rapid hypoxia, posing a greater immediate threat, requiring airway evaluation before addressing pain levels.
