Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. Enalapril maleate is an angiotensin-converting enzyme (ACE) inhibitor. 2. ACE inhibitors like enalapril maleate block the conversion of angiotensin I to angiotensin II. 3. By inhibiting the formation of angiotensin II, enalapril maleate decreases the levels of angiotensin II. 4. Angiotensin II is a potent vasoconstrictor, so decreasing its levels leads to vasodilation and decreased blood pressure. Summary of why other choices are incorrect: - Choice B: Enalapril maleate primarily dilates arterioles by decreasing angiotensin II levels, not veins. - Choice C: Enalapril maleate does not directly adjust extracellular volume; it primarily affects the renin-angiotensin-aldosterone system. - Choice D: Enalapril maleate

Correct Answer: A

Rationale: The correct answer is A because clients with Parkinson's, Huntington's diseases, or epilepsy often experience emotional challenges such as depression and anxiety due to the impact of their conditions on their daily lives. Emotional counseling helps address these issues. Additionally, these clients may struggle with basic self-care activities due to motor and cognitive deficits, making it crucial for nurses to assist them in performing daily tasks. Choice B is incorrect as clients with these conditions may experience paralysis or motor impairments, but it is not a universal symptom. Choice C is incorrect because the question does not mention bone issues in Parkinson's, Huntington's diseases, or epilepsy. Choice D is incorrect as aggression and violence are not common symptoms in clients with these neurologic deficits.

Correct Answer: A

Rationale: The correct answer is A: Liver. The liver is a common site for metastasis because it receives blood from various organs, making it a prime location for cancer cells to travel and establish secondary tumors. Additionally, the liver has a rich blood supply and provides a favorable environment for cancer cells to thrive. In contrast, B (Reproductive tract) and C (Colon) are not as common sites for metastasis compared to the liver. Choice D (White blood cells) is incorrect as metastasis involves the spread of cancer cells to distant organs, not within the blood cells themselves.

Correct Answer: A

Rationale: The correct answer is A: Use aseptic technique for the insertion site. Aseptic technique is crucial for preventing infection when accessing or caring for an invasive monitoring system like a subdural intracranial pressure monitoring system. Aseptic technique involves maintaining a sterile field, washing hands, using sterile gloves, and using sterile supplies to minimize the risk of contamination. This is essential to prevent introducing harmful microorganisms into the patient's system. Using clean technique (B) or sterile technique only when cleansing the insertion site (C) may not provide adequate protection against infection. Closing leaks in the tubing with tape (D) is not an appropriate method for preventing infection and can lead to complications.

Correct Answer: C

Rationale: The correct answer is C because pronation-supination of the hand and forearm is a characteristic movement in Parkinson's disease called "pill-rolling tremor." This movement interferes with normal hand activities due to involuntary shaking. A is incorrect because exaggerated muscle flaccidity does not lead to frequent falls in Parkinson's disease. B is incorrect as hyperextension of the back and neck is not a characteristic movement of Parkinson's disease. D is incorrect as it combines all options, which is not accurate.
