Correct Answer: C

Rationale: In this scenario, the colleague's action of informing the client that he will administer medication by injection if she refuses to swallow her pills constitutes assault. Assault is the act of threatening harm that causes fear of imminent harm. It does not involve physical contact but rather the apprehension of an imminent harmful or offensive act. Defamation, choice A, is incorrect as it involves harming someone's reputation through false statements. Malpractice, choice B, is also incorrect as it refers to professional negligence or misconduct in performing duties. Battery, choice D, is not the correct answer as it involves intentional harmful or offensive physical contact with the person.

Correct Answer: D

Rationale: The correct answer is D. When performing fecal occult blood testing, it is crucial to inform the client that the specimen must not be contaminated with urine to prevent false results. Choices A and B are incorrect because eating more protein is not required before testing, and multiple stool specimens may be necessary for accurate results, respectively. Additionally, regarding choice C, a red color change, not blue, indicates a positive test result, making it an incorrect option.

Correct Answer: C

Rationale: Calf swelling, redness, and tenderness are classic signs of thrombophlebitis. The swelling occurs due to the formation of a blood clot in the deep veins of the calf, leading to inflammation and potential obstruction of blood flow. Bladder distention (Choice A) is more indicative of urinary retention, decreased blood pressure (Choice B) can be seen in conditions like shock, and diminished bowel sounds (Choice D) may suggest gastrointestinal issues, none of which are directly related to thrombophlebitis.

Correct Answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.
