Correct Answer: C

Rationale: The correct answer is C: Activated partial thromboplastin time (aPTT). aPTT is specifically used to monitor and regulate heparin therapy as it assesses the intrinsic pathway of coagulation, which heparin affects. Options A and B, Prothrombin time (PT) and International Normalized Ratio (INR), are used to monitor warfarin therapy, not heparin. Option D, Fibrinogen levels, is not the primary test used to monitor heparin therapy.

Correct Answer: A

Rationale: Chlamydia is the correct answer. It is a sexually transmitted infection that is nationally notifiable, meaning healthcare providers are required to report cases to the state health department. This is crucial for disease surveillance, monitoring, and implementing public health interventions. Human papillomavirus, Candidiasis, and Herpes simplex virus are not nationally notifiable infectious diseases and do not require mandatory reporting to the state health department.

Correct Answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common response to acute pain due to increased sympathetic nervous system activity. Options A and B, Bradycardia and Hypotension, are unlikely findings in a client experiencing acute pain as pain usually triggers an increase in heart rate (tachycardia) and blood pressure. Option D, Hyperactive bowel sounds, is not typically associated with acute pain.

Correct Answer: A

Rationale: The correct answer is A: Constant bubbling in the water seal chamber. Constant bubbling in the water seal chamber can indicate an air leak, which compromises the integrity of the chest tube system and should be reported to the provider for immediate intervention. Choices B, C, and D are incorrect. Intermittent bubbling in the suction control chamber is an expected finding indicating that the system is working appropriately. Tidaling in the water seal chamber is a normal fluctuation of fluid level with inspiration and expiration, indicating that the system is functioning correctly. Drainage of 75 mL in the first 24 hours is within the expected range for chest tube drainage and does not require immediate reporting unless accompanied by other concerning symptoms.

Correct Answer: B

Rationale: The correct action for the nurse to take when caring for a client with Clostridium difficile infection is to place the client on contact precautions. This helps prevent the spread of the infection to other clients. Washing hands with an alcohol-based hand rub is important for infection control but is not specific to preventing the spread of Clostridium difficile. Wearing a mask may be necessary for airborne precautions but is not the priority for Clostridium difficile infection. Double-bagging linens is not a standard practice for preventing the spread of Clostridium difficile.
