Correct Answer: C

Rationale: Elevated ammonia levels in a client with liver disease can lead to hepatic encephalopathy, requiring immediate intervention. Ammonia is a neurotoxin that can cause cognitive impairment and altered mental status. Elevated bilirubin levels (Choice A) are common in liver disease but do not require immediate intervention. Low albumin levels (Choice B) and low hemoglobin levels (Choice D) are also common in liver disease but do not pose an immediate threat compared to elevated ammonia levels.

Correct Answer: D

Rationale: The correct answer is to palpate the radial pulse in the left arm. When the antecubital insertion site is on the left side, it is important to assess the radial pulse on the same side to monitor circulation accurately. Palpating the brachial pulse in the right or left arm or the radial pulse in the right arm would not provide direct information about the circulation related to the catheterization site.

Correct Answer: A

Rationale: The correct answer is A. When taking ferrous sulfate, dark tarry stools can occur as a common side effect due to the iron content in the medication. This is a normal response to the medication and not a cause for concern. Choices B, C, and D are incorrect because increased bruising, reduced infections, and amber-colored urine are not expected side effects of ferrous sulfate.

Correct Answer: D

Rationale: The recommended approach for handling aggressive behavior in a mental health setting is to maintain eye contact, offer clear choices, and set boundaries. This approach can help de-escalate the situation by establishing communication and structure. Choice A is incorrect as encouraging physical activity may not be suitable during an aggressive episode. Choice B is incorrect because avoiding eye contact can hinder communication and resolution. Choice C is also incorrect as pharmacological interventions should not be the immediate go-to method for managing aggression unless absolutely necessary.

Correct Answer: C

Rationale: The correct answer is monitoring intake and output and checking for edema. Monitoring intake and output provides information about fluid balance in the body, while checking for edema helps assess for fluid overload. Lung sounds and signs of orthopnea are more indicative of respiratory issues rather than fluid balance. Daily weight measurement is useful to assess fluid status, but it alone may not provide a comprehensive evaluation of fluid balance.
