Correct Answer: C

Rationale: The correct answer is C. Colorectal cancer screening for individuals at average risk typically begins at age 50. One of the recommended options for routine screening is a fecal occult blood test done annually. Choice A is incorrect as blood samples are not used for routine colorectal cancer screening. Choice B is incorrect because colonoscopies usually start at age 50, not 60. Choice D is incorrect as sigmoidoscopies are recommended every 5 years, not every 10 years, for individuals at average risk for colon cancer.

Correct Answer: D

Rationale: The absence of breath sounds on the affected side is a critical finding that may indicate a tension pneumothorax, a life-threatening condition requiring immediate intervention. This situation can lead to a shift of the mediastinum and impaired ventilation. Bubbling in the water seal chamber is an expected finding in a chest tube drainage system and indicates proper functioning. Drainage greater than 70 ml/hour is a concern but does not require immediate reporting unless it continues at a high rate or is associated with other symptoms. Tidaling in the water seal chamber is a normal fluctuation and indicates the chest tube system is patent and functioning correctly.

Correct Answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.

Correct Answer: A

Rationale: The correct answer is A. Stress typically increases blood glucose levels due to the release of stress hormones like cortisol and adrenaline. Elevated blood glucose helps provide energy for the body to cope with the stressful situation. Choice B is incorrect because intestinal peristalsis, the movement of the intestines, is more likely to decrease under stress due to the 'fight or flight' response. Choice C is incorrect as peripheral blood vessels' diameter may vary in response to stress, with both constriction and dilation possible. Choice D is incorrect as urine output may increase or decrease depending on individual differences and the specific stress response, but it is not a typical or direct physiological response to stress.

Correct Answer: B

Rationale: In this scenario, the nurse should choose option B, which is to document the client's condition and communication with the surgeon. By documenting the client's condition and the communication with the surgeon, the nurse ensures legal protection and maintains continuity of care. This documentation serves as evidence of the actions taken, communication exchanged, and the rationale behind decisions made. Option A, notifying the nursing manager, may not be necessary at this stage unless there are specific institutional protocols requiring it. Administering additional fluids without further clarification may not be appropriate and could worsen the client's condition if not indicated. Calling the surgeon back immediately (option D) may disrupt the agreed-upon plan of action and fail to follow the surgeon's instructions of reassessment after an hour.
